in a noticeable saving of non-ferrous inetals. 4) fly-
drogen cooling of terminal buses may also be used.
In this case, hydrogen circulates inside the buses,
since such circulation between the envelope and the
bus is not advantageous, since it presents sealing
probleme. In addition, the spacing between bus and
envelope must be incroasod. The author conaiders the
problem of determining losses in envelopes and the
thermal calculation of enclosed terminal buE,e*s. For
this purpose an experimental investigation of envelope
models was used /Re-f g, which shows that the distribu-
tion of circulating currents is practically independent
of the length. For investigating the induced currents
and the losses in envelopes of enclosed busea, the au-
thor manufactured a model of such terminal buses, shown
in figure 1. For the calculationag he used the follow-
ing conditions: a) the envelope has am infinite length,
and b) the circulating currents are evenly distributed
Card 3/5 on the envelope. The author uses for his calculations

in Onvelopou of lartO dialuete-re. The analysis of the
formulae cited in ief g shows that some of them will
not produce a fini~Fe_ result for those envelope dia-
meters used for high-ampere buses. The measurements
performed by the author show that the current distri-
bution in a three-phase bus system, located in one
plane, is different for all three buses and depends on
the phase sequence order. The currents between enve-
lopes may attain several thousand amperes undi~r actual
conditions. The results of the investigation of los-
ses in envelopes were compiled in tables 1 and 2.
The author then presents formulae for the thermal cal-
culation of enclosed terminal buses, using the Stefan-
Boltzman formula. In his conclusion, the author
states: 1) Losses in bus envelopes are commensurable

degree on the distances between the axoti of the phases
which should be taken into consideration when design-
ing terminals. 2) The heat losses of buses inside an
envelope are smaller than the heat losses of buses in
free apace by 30-50%, which leads to a reduction of
the continuously permissible currents by 16-30%.
3) The theoretical and experimental investigations show
that models may be used for the development of new bus
designs, which may be used in combination with control
measurementson experimental buses. 4) Econonical and
reliable buses may be obtained by using oil or hy-
drogen cooling. There are 4 graphs, 1 diagran, 2

ABSTRACT: A case.of a mechanic who became intoxicated with methylchloride while
repairing a refrigeration system is described. After that event he suj'fered from
~eDresqions, and with ebrietas simplex. After 2 weeks a depressive and amentia
syndrome evolved. Reserpine treatment improved the patients's condition in 8 da3m.

ABSTRACT: All of tho current industrial methods for production of mel-
amine from dicyandiamine according to the reaction
3H2C2N4 _4 2JI 6C3N6 are discontinuous. Tho reaction volume
shows a low specific output. - On the basis of the phase dia-
gram of the melamine-ammonia systemp a continuous process
was evolved in 1955 - 1958, which is characterized by the
fact that the temperature is raised beyond the critical
1 0C(to 500 - 5500C), so that rielamine is formed,

TITLE% Chromatographic separation of inicrograin quantities

KY-1 (KU-1) and K'J-2 (KU-2)
PERIODICAL; Radiokhimiya, vA, no.2, 1962, 181-184
TEXT: The object of the work was to develop a method of
chromatographic separation of Np-237 and Pu-239 uijing S'oviet
cation exchangers. The experimonts were carried out by reducing
a cation-exchanger (0.5 9) with 502 in 0.25 N 11CI containing a
known amount of Np, and Fu. The filtered resin wait placed in a
column and eluted with 0.02-N HF. The method devolopee. gave thet
separation coefficient >, 103.Np and Pu could be itsolatcd from
their mixtures in 98 t 2% purity. Conditions for the
quantitative sorption of Np on the resins were found and
distribution coefficients for Np and Pu on resin KV-1 itere
determined for HF solutions of various concentrations. NP was
eluted with 0.02 N HF and Pu with 0.5 N HF. It was found that

the resin used (0-3-0-4 mm) was too coarse for small
chromatographic columns. Consequently the experiments vere A"
conducted under-conditions in which equilibrium.could not-be
reached. The authors concluded that the use of a more finely
divided renin ifould lead to thp elution under equilibrimin
conditiong.
There are 3 figures and 4 tables.

TITLE: Aspects of using phototransistors
PERIODICALi Tekhnika kino i televideniya, 1960, no. 12, 56-62
TEXT: The authors furnish the results of investigations of the basic para-
meters of phototransiators, made from n6 (P6) transistors. More than 50%
of the phototransistors produced from a batch of transistors sclected at
randon had a photosensitivity of more than la/Im. The maximum sensitivity
in some specimens ranged between 8 and 10 a/lm. The following parametersi
were investigated: (a) transistor current photosensitivity (b)
resistance to alternating OUTrent in the dark (Ri0i (c) permlssible vo:.-
tage at the collector (d) mean value of the dark'current at the
slanting section of the vAt-ampere characteristic (1,,,t). These paramet,i-To
were graphically determined from the static and dynamic volt-ampere charic-
teristics; the former.were determined using a voltmeter and an ammeter,

whilst the latter were determined with a 50-Hz alternating current by means
of a "characteriograph" which permitted the volt-&Apere characte-Tistics to
be simultaneously read,in the dark, and at any preset illumination of the
phototransistor on the screen of an MO-I (ENO-1) oacillograph., The mean
paramotara that wore found for phototransistors with a "floating" base
ohowed that such photo brans to torn would be Ineffialant if used -for rooord-
ing amall light fluxtic with auboo(juont AMPIMOI.AtIon. Thorefor'o,the para-
motors had to be controlled eitha'~ by a wonk connootion tetw"n the b;'Isr;
and the emitter through a high resistance of 0.1 + I K-ohm, or by using,%
positive fixed bias or aelf-bima in relation to tho amitter in the base
circuit. At an optimum bias of 0.5 V, fed through a rasiat&noa of 100 k-
ohm, the phototransistor's basic parameters h n as followds 1,
from c a Is t decreaIes
50 ("floating" base) to 5,^A(Ilbound" R increases from 10
it
to 1o7 ohms; Ucd increases from 6 to 12 V (d.diode); and fi decreases from
8 ~ 0 4 a/lm. The graphic calculation and the experiment showed that by

phototransistors were investigated by means of a wide-band audio frecuency
m,easuring amplifier with a large input resistor and a equare-law detector at
the output. It was revealed that in both systems ("floating" and "bound"
base) an increase in photosensitivity entails a tenfold increaso in.the Big-
nal-to-noise ratio, provided that the optimum operating conditions are Cho-
sen. At a sign -to-noise ratio equalling 10 the minimum flux that can be
measured is 10- lm (11floating'i base) and 10-1 im ("bound" base). The fre-
quency.response of phototransistors was investiga:ted with a neon laTap fed
from an audio frequency generator. It was found that by using U "bound"
base cirouitp the frequency properties of' the phototransintore ean be im-
proved by approximately I order. Investigations showed that industrial
plants producing P6 transi3tors can start the production of phototransis-
tors without considerably changing the production technology. ~!he photo-
transistors are not suitablo for measuring small illuminances, due to their
working, ourfaco (2 mm2). The minivium illuminance at a silynal-to-

Abstract Paperiments were conducted in 1954-1956 on two collective
farns of the Omsk district on an area of 1000 hectares.
7he bushes were cut down by a cutting machine or were bur-
ned down. The lifting of the upper layer was done by a
bush plouEh with diske of 2 to 3 tracks or by mill:Lng.
Milling gave best-results. Before sowing, the soil was
rolled by waterspraying rollers. The sowing took place
in June. On peat bog soils the oat harvest yielded 16 to
18 centners per hectare, sunflower for silage, 150-210
centners per hectare, turnips, white cabbage, 350~500 cen-
tners per hectare. On sections with a lighter layer of
