iABSTRACT: Experimental data are given on the velocities of fluid flow in the inter-
iwheel clearances of a-single-stage hydraulic coupling with centrifugal turbine wheel
iand radial-axial reactor. The hydraulic coupling is shown in the figure. The
;numerals indicate the points at which measurements were taken, P is the pump impeller,
.:T is the turbine wheel and R is the reactor. The angles of all blade rims are con-
'Istant with respect to width. Testa using transformer oil at a temperature of 800C
and a pump vlocity of 1500 rpm showed a maximum efficiency of 0.83 at a transmission
ratio of 0.61. The starting conversion factor is 3.65. Spherical probes 5 mm in dia-
meter with 0.1 mm channels were used for measurements at transmission ration of 0
0.3, 0.54, o.61, 0.8 and 1.0. The experimental data for each of the five cross s;C-

tions are considered separately. The results show a complex interwheel flow structure--
in the hydraulic coupling. Tests under rated operating conditions show an approxi-
mately uniform distribution of the meridian components of velocity after outlet from
':the turbine wheel and reactor, and before inlet into the reactor. The distribution
of these velocity components is potential before inlet into the pump impeller, and
antipotential between the impeller and the turbine wheel. The distribution of peri-
pheral velocity components under these same operating conditions is potential before
~!inlet into the pump and close to uniform in the remaining cross sections. Under
;severe operating conditions, the curves for velocity distribution are distorted with
the most noticeable effect observed after outlet from the reactor and before inlet into,
the pump impeller. Under rated operating conditions, the angles of attack on the
;outer stream lines of the input edge of the pump impeller are equal to 400. To reduce
ilosses, the blades of the impeller should be profiled with a variable angle at the
!inlet to take care of the actual velocity distribution. When the blade angle is held
constant, efficiency may be improved by locating the input edge of the pump impeller
~in the radial section of the working cavity and reducing the width of this edge.
Under severe operating conditions, the angles of attack at the inlet to the reactor
reach considerable values varying from +660 for a transmission ratio of 0 to -56* when
Ithe transmission ratio is 1.0. The range of transmission ratios with high efficiencies-
'may be extended by profiling the reactor blades vith increased nose thickness or by I
,using deflectors e. the inlet. Orig. art. has: 8 figures, 1 fomula.

ABSTRACTt In 1956, time studies showed that workatoppage in ex-
cavation and development of stopes was extremely high due
to poor transportation means and badly organized loading
points.
The following reasons for the inefficiency of the under-
ground transportation is given. Of all electric locomotives,
22% are low-powered, 2-ton locomotives, 60% are contactor
and battery-powered electric locomotives with an adhesion
weight of 7-8 tons, 17% are 10-ton, and only 1% 14-ton
electric locomotives. Three quarters of all tubs have a
small holding capacity and tubs with automatic couplers have
not as yet been introduced. Conveyors, the most effective
transportation meam, are insufficiently used with only
17-0 of the all underground transportation being carried
Card 1/2 out in this way. Mainly Used, are belt conveyors of the

Goal Mines
LKU-250 type, with an output of 250 tone per hour. In 1957,
the serial output of more powerful conveyors of the KRU-350
and KRU-260 types was started. The following recommenda-
tions are given to solve the problem of mining transportations
1) a widespread introduction of powerful uninterrupted trans-
portation means, such as conveyors or hydraulic devices,
2~ more useful load and higher speed for underground trains,
3 smooth transport and 4) mechanization of all auxiliary
transportation processes and introduction of automation and
remote control.

ABSTRACT; At present the production and delivery of some now photoelectron-
-multipliers (FEV) worked out by the authors were begun on an in-
dustrial scale. They are shortly described here. 1.) The production
of the special multiplier for the scintillation-sDectrometers
45B Y -29 was recently begun. It ha3 a good amplitude-dissolving
power which is guaranteed by the comparatively high sensitivity of
the cathodes of 1the device. The integral sensitivity is higher
than 30 ~L A lm~ , on the average 40 - 45 p A Im-1 , the "blue" one
is higher than 6 p A m1-1 which cogresponds to a quantum discharge
of more than 9 ~ at X ';v 4000 )L. Besides the electron-optics
at the entrance of the multiplier guarantees a good taking over
of the electrons from the cathode to the dynode, as well as mini-
mum losses in the first cascades. The amMtude of the noise, mea-

impulse see- I- level, is not higrher than 5 + 8 keV. The light-cha-
racteristic is linear up to the amBlitude of the initial impulse
7 - 8 V at a load of about 50 1 and a parasitic capacity of
\< 10pF, with the method of operation given in the pass filter
of the device. The most important operation-parameter of any FEV io
the stability. Most of the (~ S)y -29 under the usual conditions
in the gamma-spectrometers work sufficiently stdie. Experiments
with dynodes of different alloys are now made for improving the
stability. At the same time thqinfluence of technological factors
and the construction of4ynodes upon the 'stability of the FEV is
also experimentally investigated.
2.)FEV Yrith enlarged cathode. According to the preliminary data
these multipliers have the following average static parameterst
integral sensitivity of the cathode 35 - 40 p A lm-1, the "blue"
sensitivity - 7 p A lm-1. Amplification about (2 + 5).lo5 at full
voltage of 1400 - 1500 V. At much higher voltages it can attain
107. The density of Vle heat flow from the cathode on the averaze
amounts to 5.10-15 Acm-2.
3.) "Time"-FEV. Beside the "general" parameters the minimum scat-
tering according to the time of passage of the "electron-parcel"
through the multiplier in the case of a maximum steep front of the
Card 2/4 initial impulse is also demanded of it. After the modelling of many

,New Industrial Types of Photoelectron Multipliers

variants a system was found which guarantees good focusing of the
electrons and minimum scattering of the time of flight. The cal-
culations of the maximum time-of-flight gradient in this multi-
plier system with grid. yielded a quantity of 4,4.10-10 see (at a
voltage of 100 V/cascade) whidi is 3 - 4 times less than tn the

-range of 5500 to 8000 1 is given by the bismuth-silver-cesium ca-
thodes. The experimental samples of multipliers with such cathodes
are produced in two sizes: that of the (D 3Y -2Q and in a smaller
size. The multipliers have 11 cascades. Their integral sensitivity

ABSTRACT. The multiplier is fitted with an anti mony-caesium cathode,
which is suitable for the operation with light beams hav~mg
a diameter of about 2 mm. The emitters are also Sb-Cs-coated
and are constructed in the shape of a box (see Fig.2a). There
are 7 emitters and a special anode which is in the form of a
grid, parallel to the surface of the last emitter (see Fig.26).
Dimensions of the multiplier are 58 mm in height-and 22 mm iff
diameter. Overall sensiti-Xity of the multiplier,,~-was measured
at a-light flux of 3 x 10-t Lm and the sensitivity of the
cathodes was investigated at 3 x 10-5 im, the diameter of the
light beam being 2.15 mm in each case. Results of the measure-
ments on 20 laboratory samples of the photo-multiplier are
shown in Te-,,le 1 on p.423. It was found that the average
cathode sensitivity was 28 ILAIIm. This'was thought to be
satisfactory for most practical applications., The average
Cardl/3 amplification of the photo multipliers was 101 at the overall

supply voltage of 900 V; the voltage per stage was thus 113 V
and the amplification 5.2. If t ~e overall voltage was 800 V,
-,a total amplification was 5 x 10 - Voltage current character-
istics of the multipliers were also measured and two typical
curves are shown in Fig.4; Curve M represents the overall
amplification as a*function of the inter-stage voltage, while
Curve IT represents the dark current as a function of the
voltage. lioise and threshold sensitivity of the 20 samples
were also measured and the results are reported in Table 2 on
p.424; the threshold sensitivity, as a function of the voltage
per stage, is shown in Fig.5. Anode characteristics of the
multipliers for two different valm of the output current are
given in Fig.6. The construction of the multiplier is such
that the anode current is dependent on the position of the
light spot on the surface of the cathode. It was of interest,
therefore, to investigate this effect. A beam having a diameter
of 1.05 mm was used for the purpose and the sensitivity curves
obtained by this means are shown in Fig.?. It is seen that
the edge portions of the cathode have the highest sensitivity.
This effect is thought to be due to the presende of two angles
Card2/~t the edges of the cathode. This was confirmed by the fact

109-3-15/23
A Miniature Photo-electron Multiplier with a Bulky Cathode
that, if an additional angle (threshold) was placed in the
middle of the cathode, the sensitivity had an additional
maximum in the centre of the cathode. On the basis of Figs.
7 and 8, it is concluded that the reason for the increased
sensitivity of the cathode in the regions close to the angles
is the focusing of the photo-electrons on to that portion of
the first emitter which directs the highest possible number
of the electrons on to the second emitter.

ABSTRACT: In the conference (Ref 1) last year preliminary data on the
new 13-cascade multiplier (FEU -photoelectronic multiplier -
FEM) were communicated. Tbib* aevice serves for the investigation
of nuclear processes with a fas-u sequence. The investigations
of the parameters and of the of the FER-33
recently carried out by the authors yielded the following
results: according to the technical assumptions the integral
sensitivity of the cathodes of the FEM-33 as well as of the
FEM-29 should riot be below 30 *&LA lm-1, The mean integral
sensitivity of the multiplier cathode which was dey,31oped in
Card 1/3 the last two months amounted to 40ptA lm-1 . The dependence

of the amplification of the supply voltage of three specimens
of the FEM-33 are given in figure 2 (continuous curves). For
comparison the oharacteriStiOB of three 14-ca5cade multipliers
RCA-6810 are given with dotted lines~ These curves were taken
under the same conditions. Measurements of the amplitude re-
solution of the FEM-33 showed that it is by no means inferior
to other FEM's. The noise level of the FEM-33 according to the
scale of the NaJ-(Tl)-GS137 is of the order 3 - 4 keV (at a
counting rate of 50 pulses per sec). The classification of 50
specimens of FEM-33 according to the pulsed output current is
given in figure 3. The weakest currents equaled 0,3 A, the
highest about I A. Investigations of the linearity of the
output currents at a voltage of the order of 4 kV showed that
on the average the FEM-33 operate linearly up to 0,5 A. The
deviations range from 0,4 to 0,8 A (Fig 8). The width of the
coincidence curve of specimens of FEM-33 with a crystal and
with a preparation CoEO in the coincidence circuit is between
the limits of 2 to 4 microcculomb . seo (at a counting efficiency
Card 2/3 of 50%). The data obtained by oscillographs showed that the

to produce spectrometers FEM with a better resolution, it was
attempted to produce spectrometeTa FEM with multialkali
cathodes (as, for 6xample Sb-N&-:K,, or Sb-Na-K-Ca oathode3)
(In figure 3 the characteristics of these cathodes are given).
The FEM-24 went into series produo-lion in the last year (Ref 1).
The authors carzied out exper-iments with good p~~oapects with a
multiplying system with torcidal dynodes of AI-Mg-alloya~ One
of the new types of midget spectzometera FEM is desa-ribid as
follows: cathode diameter 25 mm,, maximum accket dfameter

is equipped with a h4gh-res4ia'anoR potentiometer. From the table
can be seen that the resolztion of therse multipliers is of the
same order as that of M-29. The basic features of the design
of the FEM-31 are given in reference 3. The spectrometric re-
solution of the FEK-31 which was measured with a crystal with
a diameter of 14 mm. was within the limits of 8,5 - 14- An FEM

TEXT: Two new types of photoelectronic multipliers ~3Y-35 (F-lU-35) and
~)Y-29 (FEU-29), as applied to scintillation spectrometers, were worked
out by the authors. Full particulars are given of FEU-35, less of
FEU-29. The cathode diameter of FEU-35 is 25 and 34 mm for 108 mm length.
To improve electron-optical properties of the input a focusing cylinder
(of Fig.1) is applied. This cylinder permits better combination between
the*axial-symmetric inlet of the multiplier and the inevitably asymmet-
rical first cascade of the multiplier system. The new inlet system
secures a good energy resolution. As much as 600 FEU-35 devices were
checked for amplitude resolution (Fig.2) and for the amount of the
energetic noise equivalent (Fig-3). Fig.4 illustrates the average

dence of the output signal amplitude on the I-quantum energy is secured
up to amplitudes of the magnitude 10 v for 50 k92 and 10 pF. The sensi-

second multiplier (FEU-29) suitable for y-spectrometry has a cathode
with the dimensione 38-48-190 mm- Its amplitude resolution is given
with 7-5 - 1 Wa. It exhibits an especially low noise level (1 - 2 kev)
in the 50 imP/Sec level. To test the stability of the photoelectronic
multipliers under work conditions*a special device was constructed,
permitting measurement of the change with time of the Cs137 photopeak

TEXT: A large number of photo-electron multipliers was analysed and the
characteristics of their photocathodes were investigated. rhe
photomultipliers were of the standard industrial or laboratory type.
First the spectral characteristics of a number of multistage photo-
electron multipliers with bismuth-silver-cesium cathodes and
aniimony-cesium emitters, as well as Al-Mg alloy emitters were
investigated experimentally. Some of these are shown in Fig.1,
where the wavelength is shown on the abscissa in microns. Some
spectral characteristics of the multipliers with oxide-silver-
cesium cathodes were also investigated and the results are given
graphically. It is concluded that the shape of the characteristics
of the tubes with antimony-cesium emitters is due to the strong
ads tion of cesium by the emissive layer, so that a film of free

Photo-electron Multipliers
The secondary emission coefficient of the photomultipliers was
investigated at a fixed voltage and it was found that it varied
considerably from sample to sample, depending on its processing
conditions. The average efficiency characteristics of the
secondary-emission surfaces were also investigated. The efficiency
coefficient is defined as the average gain of the multiplier per
stage; this was obtained by measuring a large number of samples and
determining the voltage and sensitivity distribution for the cathodes
(I.Ya.Breydo et al., Ref.1). In general, the distribution curves
have thi form of the normal Gaussian distribution. The average
gain coefficients per stage for a number of standard multipliers
produced in 1959 with various emitters were investigated by the
above method and the results are given in a figure, while the
details of the multipliers are shown in a table. The same figure
shows also the gain of some of the American tubes (made by RCA).
From the experimental data given in the figures it is seen that
for the same interstage voltages the gain of the multipliers with
antimony-cesium emitters is much higher than that of the tubes with

alloy-type emitters; the highest gain is obtained in the multipliers
with a lateral optical input. The efficiency of various multiplier
systems is approximately identical but the coefficient of the
secondary emission as a function of voltage differs considerably.
The effect of the presence of alkali metals on the secondary
emission coefficient of alloy-type emitters was also investigated.
According to N. Schaetti (Ref.3), M. Biermann and W. Kz:;iger (Ref.4)
and Ye. G. Kormakova and V. G. Pavlovskaya (Ref-5), the presence of
cesium leads to an increase in the secondary emission coefficient 0.
This effect was investigated for the Al-Mg emitters for the
multipliers provided with a heated cathode. The overall gain of the
multipliers was measured during various processing stages and the
average gain was then calculated. The results of these measure-
ments are given in Figs. 4 and 5- These show the gain per stage
as a function of the interstage voltage; curves 1 and 2 in Fig.4
illustrate the effect of thermal activation, curves 11and 21
represent the processing with K-Na, while curves 111 and 211 illustrate
the Influence of Cs processing. Curves 1,2 and 3 in Fig-5 show

the gain after the thermal activation, while curves 11,21 and 31
illustrate the effect of Cs processing; in both figures the same
emitters made of Al-Mg alloy were used. The dark current of the
multipliers, which determines their sensitivity, was also investi-
gated. It was found that the spread of this parameter, at a given
sensitivity, in the standard commercial tubes was very considerable
(several orders) and was much higher than the spread of other
parameters. It was found that oxide-c,*Aum cathodes give a
constant thermal component of the dark current, which does not
Increase when the cathode is illuminated. On the other hand, an
Sb-Cs cathode, operating with antimony-cesium emitters, has a very
low thermal current. The multipliers with various other types of
cathodes and with Al-Mg emitters give almost identical results an
regards the thermal current. It is thought that the reason for
the comparatively high dark currents in the multipliers with Sb-Cs
cathodes and alloy-type emitters, as compared with other cathodes
and emitters, is the luminescence of the alloy-type emitters.

TEXT: Some properties of the monocrystalline photoolectronic multipliers
of type ~3y -36 (FEU-38) and Oy -51 (FEU-51 ) with s emi-trans parent
Sb-Na-K-C3- photocathodes are described. The author's completed the
development stage of these multipliers'in 1961 and series production is ni)w
being planned. The FEU-51 multiplier for light measurements has a cathode
of 25 mm diameter and 11 multiplying cascddes. The basket-shaped emitters
were produced from the activated 6p6-2 (BrB-2) alloy and activated before
the multiplying system was mounted. The alkaline metals were prepared by
heating tablets of the chromates of K, Na, Cs and of well purified pow-
derized'titanium (reducing agent). The logarithms of the sensitivities
and the dark ourrent increase almost linearly with the voltage. For FEU-38
this inorease is steeper than for FEU-51. FEU-38 and FEU-51 are Densitive

TITLE: On the Part Played by the Surface in Thermal Propane Decomposi-
tion
PERIODICAL: Zhurnal fizicheskoy khimii, 1959, Vol 33, Nr 10, pp 2259 - 2263
(USSR)
ABSTRACT; The fact that thermal deoomposition-in never completely inhibit-
ed by various inhibitors is asoribed by Kinshelwood (Ref I) to
the two parallel mechanisms of decomposition, namely, the chain
mechanism (inhibited by the inhibitor) and the molecular mecha-
nisis (which in not inhibited at all). This assumption is, how-
everp irreconcilable with experimental results obtained from the
cracking of hydrocarbons in the presence of deuterium-bearing
molecules. Hinshelwood (Ref 9) found that the rate of
thermal decomposition of 2-methyl pentane was independent of a
variation in the ratio S:Y (S - surface of the reaction vessel,
V - its volume)* Rice and Herzfeld (Ref 10) have, howeverp shown
that.the absence of any dependence of the reaction rate on the
ratio S:V is not indicative of the homogeneity of a chain forma-
Card 1/3 tion or destruction. Since the hypothesis of a homogeneque

Decomposition
mechanism of chain formation or destruction could not explain
experimental observations# V. V. Voyevodskiy and V. 1. Poltorak
(Ref 11) assumed that the formation and destruction of the
chains be heterogeneous processes and the observations are to be
attributed to variations in the surface of the reaction vessel.
Consequently, they suggested a definite aourse of this prooesso
In order to check this hypothesisp the authors investigated
systematically the influence exerted by the ratio S:V on the
kinetics of propane craokinge Further, they examined the pos-
;!k~lity of intoxicating or activating the vessel surface. The
action rate was determined from the pressure rise (measured
by means of a diaphragm gauge) at a propane pressure of 25 torr
and a temperature of 610 C. For this purpose, they used a quarts
tube with and without content (twelve-fold variation of the S:V
valued When the S:V value was increased by twelve timest the
reaction rate dropped to one-=fourtho Experimental pretreatment
of the vessel surface with various salt solutions indicated that
an Xg(ClO 4)2 solution increases the reaction rate (Fig 4)o In-

Decomposition
of NO + H 25 indicates that at the beginning the reaction pro-
ceeds like an inhibited reaction, is then accelerated and
finally passes through a maximum (Fig 3). In order to explain
the problem as to whether the afore-mentioned hypothesis is
correct$ or whether the influence exerted by the surface of the
reaction vessel upon the thermal decomposition should be ex-
plained in another way, further investigations are needed. There
are 4 figures and 12 references, 4 of which are Soviet.

ultraviolet radiation
PERIODICAL: Plasticheskiye massy, no. 1'1, 1962, 3-6
TEXT: Films of polystyrene (PS) and of its copolymers OV4-10 (SN-10) and
C4-28 (8N-28) containing 10 and 28~ polyacrylonitrilet respectively,
were irradiated with ultraviolet liPt from a*mercury lamp
(4 - 2463-5770 %; 0. - 0-0152 cal/cm. -min) -at 25-300C. The film thickness
was 50-100 g, the molecular weight 118,000-194,000, the time of irradia-
tion about 400 hra. The &mount of the resulting insoluble fraction and
the intrinsic viscosity (ILI of the soluble fraction were determined.
Results: (1) The amount of insoluble fraction rose with increasing
acrylonitrile content, and even more co after reprecipitation.
(2) Molecular weight and [V dropped rapidly within the first 50 hrs, and

approached a constant value after 200 hra. The content of acrylonitrile
did not affect the course of these curves. Samples of high molecular
weight were destroyed faster than samples of low molecular weight.
(3) After 400 hrs irradiation, the content of peroxide-oompounds was
m6% in Ps and 0.08% in SN-28. (4) The spectra of the irradiated PS
films showed a formation of carbonyl groups (1700 om-1 band); further, a
weak band appeared at .-3400 cm-1 (OH groups), and a broad one at
1100-1300 am-1. In SN-28, a 1720 cm7l band was observed which may due to
aldehydes, ketones, or aromatic ethers. (5) Formation of volatile
products was not observed after 60 hrs irradiation at 60-700C. Here,
the cxygen content in PS increased from 0.2 to 2%. Addition of
0-5 mole% of benzoyl peroxide increased the degree of destruction to the
6-8fold without any change in the spectra. An attempt was then made to
stabilize SN-28 by adding substances having an absorption maximum at
300-400 mg. Results: (a) 0.5 mole% admixtures of P-naphthyl salicylate,
disalicylidene ethylene diamine, its copper salt, 4-propene oxide-2,4-
dihydroxy benzophenone, 2,4-dibenzoyl resorcinol, a reaction product of

PERIODICAL: Kauchuk i rezina, 10,59, Nr 2, pp 38-40 (USSR)
ABSTRACT: This technique enables hoses of any length to be
produced, whereas those wound on mandrels are usually
limited to 20 metres., The layout of the plant is
shown in a diagram. The --rubber-mix i4s fed into a screw
extruder to produce a tube which is then cooled. The
extruded tube is taken through two braiding machines
with intermediate impregnation and drying. The braided
pipe, after being coated with a rubber cement, is given
,an outer covering of rubber applied by a beva-1led head
screw extruder. The pipe is then cooled and the outer
covering is perforated so that the air in the braid can
be vented before the next stage. This stage involves
sheatEng the pipe temporarily with lead. Before the
lead is applied the pipe'is dusted, preferably with
graphite,,to prevent adhesion of the lead to the outer
Card 1/3 rubber covering. The temporary lead sheath with a wall

pressure, and its ends are sealed. The sheathed pipe,
filled with waterl is rolled onto a drum carried on
a trolley and put into a vulcanizing chamber. On
conclusion of vulcanizing the lead sheathing is stripped
and re-used. Particular points mentioned are: the
necessity for accurate tension control of the braiged 0
threads (at about 500 9). lay up Qf the braid at 3 to 5
less than the optimum angle of 54u441 since the pitch
of the first braid will increase 5 to 8 mm during
subsequent operation. Introduction of a supplementary
pull through roll between the two braiding machines, and
another after the second braid is applied, were found
essential. Separate speed control of the braiding

necessary to prevent cver--stretchiiv, of the inner
rubber tube. During the braiding aLd impregnating sta6es
the internal pressure in the tube, which plays the part
of a soft mandrel, should be between G,10 and 0.15 atm.
Less pressure leads to reduction in diameter of the hose
during braiding, over prensirs leads to swellings and
porosity. The internal pressure can be raised to
4 atm. while the out-er rubber cover is applied. At the
present time two plants are in operation producing
pneumatic tubing 18 mm internal diameter hr working
pressure of 10 atm, and a third plant for 9 ram diameter
pipe. The cost of the mandrelless process is not at
present less thar- by the normal method, b-ut it is
expected that with further improvement of the process
this will be redu~~ed. There is one figure.
