M-1ATIONi A vacuum system was constructed for obtaining semitranparent dielectric
and tetal-dielectric mirrors with interference control of the optical thickness of
of the layer during the time of operation. A method was developed for obtaining
metal-dielectric mirrors for Fabry-Perat interferometers, having favorable optical
parameters in the ultraviolet region. With the aid of the prepared interferometers
the authors measured the isotopic shifts in several ultraviolet lines of Cd II and
Zn II and the electric qiwArupole momenta of the stable isotopes Sb12-1 and Sb'23.

ABSTRACT: RE1301 microwave spectromoters~. used irk the observation of electron para-
magnetic resonance (E?R) signals, have a low sensitivity due to the zero drift. InstzL-
ment sensitivity can be improved by decreasing the zero drift through additional modu-
lation of the magnetic field with a frequency of 50 cps. These conditions produce a
signal voltage with a frequency of 50 cps at the output of the first synchronous detec-,
tor. The signal voltage is being amplified in a low-frequency amplifier and detected ;-
in a second synchronous detector. At the outlet of the second synchronous detector the
voltage,, being close to the second derivative of the absorption line, is amplified an~j

TITLE: Tho Preparation of Ion Exchange Resins by Pearl
Polycondensation - Relation Between the Basic Hydrodynamic
Parameters and the Size of the Apparatus

ABSTRACT: The authors investigated conditions for the pearl
polycondensation of the ion exchanj',,e systems FV, MFD
and L, and derived as first approximation the rule of
the required number of rotations of the agitator. The
method of the experime nt was described in an earlier
publication (Ref 10). The same type ol' r-:3acLor and

The Preparation
Relation Between
the Apparatus
of Ion Exchange Resins by Pearl Polycondensation -
the Basic Hydrodynamic Parameters and the Size of
between 350 litre and 1 200 litre but the ratio of the
agitator to the reactor remained constant. Experimental
results show that a constant value of the Frouae number
should be maintained for mixing systems with a "vortex"
motion of the liquid mixture,, The initial value should
be verified in a reactor with a minimal diameter of
300 mm. A more satisfactory distribution of the Eranules
is obtained in larger apDaratus. Temperature conditions
during polycondensation can be adjusted by decreasing
the temperature and extendin6 the reaction time, These
rules are not applicable in general, but give useful
indications for the regulation of suspension polyconden-
sation reactions. There are 6 fiGures and 13 references,
8 of which are English and 5 Czech,,

TEXT: The liquid components and the gas are continuously forced into
the reaction vessel where the mixture passes through a system of perforated
baffles (PB) with holes of gradually decreasing size, thus forming a foam.
A propeller-type agitator is used to form vort.ices in the flow; this being
necessary to mix up the components and prevent damage to the foam. During
the time of passage through the reactor the condensation reaction sholuld
reach a stage such that the emergent product is a liquid but stable foam.
.The foam is poured into molds where polycondensation is completed and
excess solvent drains off the product. Example. The following are 2
forced into a 1-litre reactor having 10 PB with 1 - 0-05 mm holes (2 cm
hole area per PB): (a) 1 1 air, 5 9 5A aqueous solution of dibutyl

ABSTRACT: Th order to overcome the disadvantages of preivious methods of eliminating
-I inWbitore from monomers before polymerization (e.g. by distillation, leaching with
alkali or acid solutions, the vacWM method, eto.), the authors suggent the use of ton
exchange resinscapable both of Ionic reactions and adsorbiag weakly Ionizable and noa-
Ionizable substances. When saturated with Inhibitors, the resin is converted to a Cl,
form by a dilute bydrochloric acid oolutfoa, and then to an Off-form by an aqueous
bydroxidesolution. The experiments described here employed a 3% IICI solution in the

TITLEs Fick's diffusion equation
PERIODICALs Inzhenerno-fizicheskiy zhurnal, v- 5, no. 2, 1962, 101 - 103
TEXT3 The system nitrogen - carbon dioxide has been studied in the light
of Fick's equation near the critical point. At 150C and 105 at, the voluBv
is largely dependent on the composition in a certain range of concentraticna
(Fig. 1a). This dependence of volume on the molar fraction of the compo-
nent results in a complex dependence between it and the volume concentra-
tion (Fig. 1b). In the section AB, the component diffuses from B to A, L/Y
which requires a negative diffusion coefficient in Fick's equation dm/dt
-DSgradC, where m is the amount of substance diffusing in time t, D is
diffusion coefficient, S is the diffusion area, and C is the volume con-
centration of the diffusing substance. According to Fick's equation, the
rate of diffusion should be zero at point A; however, since diffusion also
takes place here, the diffusion coefficient would become infinitely great.
These difficulties can be overcome by regarding not the gradient of volume

TI"LTE: Riser with an air gap in the wall
PERIODICAL: Metallurg, no. 5, 1961, 15 - 18
TEXT- Risers used at "Azovatal'" for delayed cooling of feed head metal.
are lined with chamotte bricks. The lining is 120 mm thick. Heat Insulating
conditions can be Improved by employing Insulated bricks, and the best means of
insulation for this purpose is air. Investigations were made to use tho heat
insulating properties of an air gap In the lining of risers. The use of shaped
bricks, which Is the simplest method employed at the KKK, was not possible at
Azovstal' due to the lack of a ceramic shop. Therefore., standard brick dimensions
and shapeshad to be employed. The existing design of risers was modified by
two methods: 1. In the shell of a conventional riser, 8 - 10 mm thick steel
sheets were inserted and fastendd by electric welding process in such a manner,
that an internal shell was formed that was separated from the external shell by
a 70 mm wide gap. The gap was lined with chamotte bricks. 2) A special riser
was employed with horizontal ribs in the center of the shell height, supporting

Riser with an air gap In the wall AO(ZIA101
the bricks, Between the brick lining and the shell there was a 60 mm wide air
gap. Heat balances were drawn up for conventional and experimental risers and
for this purpose the distribution of temperature along the wall thickness of the
risers was determined. Heat losses in the risers are characterized as follows:

Improved heat insulation reduces the metal volume In the feed head and increa6cz
the ingot weight. The upper section of the ingot which in moot contaminated with
non-inetallic impurities, can thus by cut off, Experimental*castings made with
the new risers showed satisfactory results. However, their large-scale production
was impeded by the low stability of the lining. Therefore, a new variant of the
risers was designed (Figure 3) where thd uniform suspension of the ingot over the
whole perimeter of the mold and riser butt line, is assured by an excess of' the
cross section of the riser (885 x 790) over that of the mold (865 x 770). Grooves,
50 mm wide, in the riser shell prevent the falling out of the upper rows of the
lining, and 50 mm - diameter apertures are provided in the walls for the elimina-
tinn of gases from interdal cavities. Experiments showed that risers lined with
straight bricks were not less stable than those lined with shaped bricks. Their
use will reduce rejects due to contamination3 with non-metallic Impurities. There
are 3 figures.

ro CT 2233-43 (GOST 2233-43) 14.5-16.5% Si. 0.5-0.8% C, 0-30-0-8G% Mn and
less than 0.1% P and 0.07% S. The plant uses the green sand molding method,
the castings are shoken out at 750-8000C, the inner stresses are removed by Y
soaking the castings in annealing furnaces of identical temperatures for 2
hours and then having them to cool. After annealing 'the castings are clean-
ed and subjected to hydraulic tests at 5 atm. Among the most frequent de-
fects are gas cavities. An analysis showed that the greater part of the gas-
es during induction smelting is added to metal by ferrosilid. Therefore,
according to the new method, only ferrosilid is subjected to pre-melting, all

other ingredients, i.e. pig iron, carbon steel,etc., are prepared as usual.
This reduced the quantity of recast material and the costs and increased the
productivity. Another defect occurring frequently were hot cracks. These
decreased rapidly after the temperature of the furnace was raised to 1 1 460-
1,4800C. Teats revealed that, if ferrosilid is overheated to lo460-1,14800C
duringsmelting, variations between 1,240-1,5600C of pouring temperature do
not cause hot cracks in castings. These experiments showed that overheating
of ferrosilid to i,4800C prevents the formation of gas cavities and hot
cracks. A considerable amount of rejects was caused due to cold cracks by
intense partial overheating during emery cleaning. Castings are water-cooled
during this process and no more cold cracks originated. A specific defect
of ferrosilid castings was fine kish which appeared after final abrasion.
This was due to the displacement of carbon by silicon. It was established
that at an amount of 0.60% C (at 15-15.5% Si) there are no rejects due to
kish. Less than 0.55% C increases the brittlenese of castings. The work
carried out in respect to new smelting method for ferrosilid, determination
of the necessary quantities of carbon (0-55-0.6VIa) and water cooling of cast-
ings during emery cleaning aided to decrease the amount of rejects caused by
