contradict the similarity in dimensions of isotactic and atactic chains
of polystyrene and polypropylene, but indicates a considerable difference.
in the temperature dependence of their macromolecular dimensions. The I
theoretical data for'isotactic polysty.Lene show that d 1n hT/d In T= -1,:

0
data for atactic polystyrene show that d In h,,/d kn Tc--0-5 it follows
that atactic polystyrene contains comparable numbers of.isotactic and
syndiotactic monomer units. This confirms the stereospecific effect due
to the end of the gro%ing chain according to J. Fordham (J. Polymer Sci.,
39, 321, 1959).

TEXT: The static electric strength of a high voltage rectifier
with no current drawn at Hg vapor pressure within the limits 1-2
microns Hg, is determined by the laws of breakdown in vacuo. When
the rectifier is loaded'. the pressure observed at the walls and side-
regions of the anode structure is 3-4 microns Hg, so that mercur
condensation may occur at surfaces having a tempei~ature of 30-40XC. 1-r
The condensate drops, falling on to the more heated parts, may in-
troduce short duration (up to I sec) increases in pressure - up to
6-8 microns Hg at the anode end. In these conditions the breakdown

The influence of intermediate... D201/D302
is determined by the ignition of the working glow discharge, In-
vestigations have shown that the presence of intermediate electrodes
- inserts in the anode assembly increases the value of the break-
down voltage with increasing vapor densities, The effect becomes
more pronounced with the decrease of the exposed surfaces of inserts
and with the increase of their thickness. For a number of inserts I<
greater than two, the breakdown voltage remains practically constant
and independent of their numbers, provided their geometrical dimen-
sions remain the same. In the presence ol inserts the breakdown
voltages for vapor of Hg, air and H2 remain constant; in intervals,
without the inserts., the breakdown voltages decrease with the ey-p-
eriment being reper-ited. Pre-ageing by means of a glow discharge
in an inert gas seems to be the most effective method of cleaning
the surfaces. The pre-ageing conditions are given together with
the curves of breakdown voltage characterising a well pre-aged rec-
tifier. 4 references. L/-Abstracter's note: Complete translation_7

TITLE-. Measuring the mercury-vapour density in the anode spot

TEXT. In high-voltage mercury valves -intended for
transmitting d.c. power there are considerable -fariations in the
distribution of mercury-vapour density. The vapour density was
measured in different parts of an operating valve by measuring
voltage variations on a small probe. In its initial form this
method was suitable only for measuring the density in the
immediate neighbourhood of the main are. However, it is of great
Interest to measure the vapour density in the trans-anode region
which has an important influence on the electric strength of the
valve. For such measurementsl V.I. Yemellyanov developed a small
probe with local ionisation, with an incandescent cathode and art
additional annular anode. The discharge current in the

additional anode circuit was mainta-ined at 70 � 5 mA. A" full
load the vapour density in the trans-anode region was found to be
3.5 microns in valve type BP -9 (VR-9) and 4.1 microns in valve
type BPH -58 (VRN-58) instead of the value of 1.2 microns whi-ch
corresponds to the cooling oil temperature. The high vapour-
density is apparently associated with the circumstance that the
dis,charge is acaompanied by longitudinal and transverse pressure
gradients. The cathode chamber walls being at comparatively low
temperature, large drops of mercury condense on them. on falling,
these drops can lead to a temporary rise in the vapour density
and to reduction in "he electric strength of the valve. The
::-eliability of high-voltage valves should be in--reased by raising
the wall temperature of the anode spot as --ompared with existing
designs, for example, by additional external heating.

Mercury Rectifier
PERIODICAL: Radiotekhnika i elelctronika, 1959, Vol 4, Nr 8,
PP 1278 - 1283 (USSR)
ABSTRACT: Investigation of the influence of the intermediate
electrodes on the ignition of gas discharges (mercury
discharge, in particular) was carried out by means of
the rectifier shown in Figure 1. The anode input of this
tube is surrounded (see the figure) by the concentric
cylinders of a capacitive voltage divider, the inter-
cylinder insulators being made of steatite.. The
intermediate transverse electrodes or so-called "inserts",
in the form of discs provided with ring slots and
circular holes in the middle, were attached to the end
of the concentric cylinders. All the components of the
rectifier, except the insulators, ivrere made of high-
quality steel, the principal insulator being of porcelain.

Influence of the Intermediate Electrodes on the Ignition Voltage
of a Self-sustaining Discharge in a High-voltage Mercury Rectifier
Full details of this tube can be found in the authors'
earlier work (Ref 1). The Paschen curves for mercury
vapour and various gases were taken at a voltage of
300 kV. The measurements were first carried out while
the tube contained four transverse electrodes or inserts.
The inserts were then taken out and the sharp ends of the
capacity-divider cylinders were provided with ring flanges.
The results of the measurements are shown in Figures 2
and 3, where the ignition voltage U s is plotted as a
funct7ion of P 0d where P. is the gas pressure referred
to 0 OC and d is the distance between the grid and the
anode (this was equal to 15 cm). Figure 2 shows the
curves for the case of mercury vapour, while those of
Figure 3 are for the rectifier filled with air. Curves I
of Figures 2 and 3 were taken for a discharge gap
without the intermediate electrodes, while Curves 2 were
measured in the presence of the inserts. It is seen that
Card2/3 in the latter case, the curves are shifted to the right,

SUBMITTED:
relatively to the curves of a "free" gap. At a mercury
vapour pressure of 4 x 10-3 mm Hg, the breakdown voltage
of a rectifier without inserts is about 70 kV, while in
the presence of the inserts, it is about 250 kV. The
effect of the geometrical dimensions on the inserts was
also investigated: this is illustrated in Figures 3, where
Curve 3 was taken for the tube with one insert, whose
thickness was 1.5 cm; Curve 4 was taken when the insert
had a thickness of 3 cm. It is seen that by increasing
the thickness of an in~sert, the Paschen curves are again
shifted to the right. There are 6 figures and 6 Soviet
references.

Aleksandrov, D.D., N.F. Olendzeskaya, and S-V. Ptitsyn . Investigation of
Electric Strength of High-voltage Kercurj ~Rectifiers_ 5
Experimn~al investigation of mercury rectifiers was extensively carried'
out recently by NIIPT of NES (Direct-Current Scientific Research Insti-
tute of USSR Ministry of Electric Power Stations) in substations of the
Kashira-Moscow and Stalingrad-DonbaBs eiectric transmission systems. The
"Circulation m-nometer", recently developed by NIIPTmade it possible to
investigate the effect of foreign gas admixtures in mercury vapor on the
electric strength of a high-voltage rectifier. The results of this in-
vestigation have now been introduced in practice. There are 9 diagrams
and drawings, and 13 references, of which 5 are Soviet, 5 Fnglish and
3 French.

Experimental investigation of cathode spot firing carried out in the
laboratories of NIIPT has proved that dielectric ignitors are free of
the many disadvantages characteristic of semiconductor ignitors.
Dielectric ignitors are recommended for use not only 1h mercury recti-
fiers, but also in various gas-discharge devices where forced repetitive
firing is required. There are 9 diagrams and drawings. and 7 refer-

Investigations carried out by V.D. Andreyev and B.G. Mendelev in _.
1949-1950 at VEI on voltage distribution in the plate circuit of a type
V-1(VR-50/120) mercury rectifier showed considerable unevenness of
distribution. The recommendation was to increase the power of the
plate voltage divider. In 1953 at the Electrovacuum Laboratory of
NI= a series of measurements was completed by V.A. Dolgikh, I.G.
Goloshchekin and N.I. Lavrov (and in 1954 V.A. Ivanchenko) on the
dependence of voltage distribution on operating conditions. The
measurement method was developed by L.N. Volkov and D.D. KnyRzev and
was based on the use of an oscillograph and a capacitive voltage-
divider. In conclusion, the authors recommend some changes in operat-
ing practice and in design. There are 3 tables of oscillograms,
4 diagrams and 5 Soviet references. -

Berlin, Ye.M. Current Regulator for H-V D-C Transmission Lines - 201
A current regulator, developed by Tekhbyuro MRS and installed in the
Kashira-Mscow d-c line, proved tobe too-complicated and not sufficiently
reliable because of the great number of tubes-requIred'(sbout 20). An-
other type of current regulator ( a contactless type developed in 1944-
by Professors I.L. Kaganov and A.A. SELkovich) also was found unsuitable
due to its lag and narrow zone of regulation (500-6oo). The author was
commissioned to design a "tubeless" current regulator, which he completed
in 1952. Experimental investigations on it proved that the previous di&-
advantages were removed. There are 5 diagrams and 3 Soviet references.

Capacitors For D-C Transmission Lines 282
The author describes a method of reducing tke cost of capacitor batteri6s - *
operating in ripple voltage circuits by using cable paper in their taanufac~-
ture. Cable paper costs 10 times less than coawntior*1 capacitor paper
but its electric strength also is less and theretore its thickness mut be
greater. In determining the cost of Irva capacitors the author draws on
the experience of the high-voltage laboratory of LPI (Leningradskiy poll-
tekhnicheskiy institat) where cable-paper capacitors for d-c and ripple
voltages have been produced on a semi-industrial scale since 1938. The
technical editor suggests that plants manufacturing capacitors consider
the author's results when producing capacitors for the above-mentioned
conditions. He notes, however, that the cost relationships advanced by
the author cannot yet be considered justified owing to the lack of operating
experience which would indicate a long service life of cable-paper capacitors
in comparison with conventional capacitors. In his comparisons the
author used 35-40 n/mm as the working voltage density. There are 2
diagrams and 4 Soviet references.

TITLE-. The Electric Strength of a High-Voltage Valve (Elektriches=

PERIODICAL& Zhurnal Tekhnicheskoy Fiziki, 1956, Vol. 28, Nr 4,
pp~ 896-907 (USSR)
ABSTRACT. The electric strength of a standard valve in a static state
without load current in dependence on the pressure of mer=
cury-vapor, hydrogen, helium and air in the valve as well
as on the interelectrode-distance was investigated here.
It is shown that the electric strength of a high-voltage
valve is determined by the rules governing the high-vacuum-
breakdown. This law is observed in the case of an inter-
electrode-distance equal to 15 cm up to pressures of the
order of magnitude 4-5-16"3mm torr in the case of air and
mercury-vapors. 7-8-10-Imm torr in the case of hydrogen
and 12-18,161 mm torr in the case of helium. The transi

The Electric Strength of a High-Voltage Valve 57-28-4-34/39
which follows Paschen's law takes place over a certain
intermediate domain where the breakdown voltage decrease
with a rise of pressure and with a reduction of the inter.
electrode.-distance Under the conditions eXiBting here the
magnitude of the breakdown-voltage is influenced by the shape
of the applied voltage., A pulsating voltage with a frequency
of 50 cycles increases the value of its breakdown in the do-
main of the vacil-um-breakdown, in comparison to the direct
voltage, by almost 5o%.

Abstract An experiment was carried ot ~.t orri two groups of lactating
Cows of the Kholinogory breed. The first group received
in its daily ration an average of 25.5 kg of cora-clover
silage, 3.1 kg of hay., 4 kg of oilcake and 19.3 kg of
turni s- the second group was fed rations co osed of
P MP
22.3 kg of all-corn silage., 3.9 kg of hay., 4.5 kg of oil-
cake and 16 kg of turnips. Inclusion of corn-clover sila-
ge into the rations aided better utilization of digestible
nitrogen of the feeds (by 9.4$), Ca (by 9%), P (by 6.7%),
and increased energy metabolisn (by 3,376 kcal.).
