TEXT: 1) Germanium rectifiers. - The author presents the. main technical
data concerning the germanium rectifiers manufactured to-day in the Soviet Union,
and particularly at the "Elektrovypryamitell" Plant. These data are grouped in
four tables. The author reproduces the recommendations of the Commission of Con-
version Technique at the GNTK USSR concerning new classifications of germanium
rectifiers: a) - classification according to the permissible amplitude of the re-
verse voltage. There are seven classes, specified in a table. b) - classifica-
tion according to the voltage drop (forward voltage drop in single-phase, half-
-wave current flows through the rectifier). There are five groups, specified in IV
a table. c) - The germanium rectifier types ("VG-5" to "VGV-1000") are limited
to eight groups: five with air cooling ("VG") and three with water cooling ("VG-V")
A table shows the voltage drop and the permissible amplitude of the reverse vol-
tage for all these types. 2) Silicon rectifiers. - The author presents some gene-

ral considerations. He states that thi Laboratory "VEI Imeni V. I. Lenin" has
designed silicon rectifiers: "VK-10" for 10 amp and 50 - 200v; "V. 50" for 50 amp
(without radiator) and for 100 amp (with radiator) -50 - 200 v; "V-K-100" for 100
amp, 50 - 200 v (all these types are with air cooling), and "VKV-200" for 200 amp
with water cooling. These designs have been put into production. The main tech-
nical data of these silicon rectifier types are presented in two tables. (Sili-
con rsatifiers for 400 milliamp. 100, 200, 300 and 400 v are also manufactured.1
The new classifications recommended by the "GNTK" Commission for silicon recti-
fiers arei a) - classification according to the permissible amplitude of the re-
verse voltage. There are ten classes, specified in a table. b) - classification
according to the voltage drop. There are five groups, specified in a table. 0 -
The Silicon rectifier types "W-10" to "VKV-1000" are limited to nine groups: six
with air cooling ('W") and three with wxter cooling ("VKV). A table shows the
voltage drop and the permissible amplitude of the reverse voltage for all these
rectifi,sr'tYPes. 3) Controlled rectifiers. The author presents the parametors
of four manufactured variants of controlled reotifier as follows: the average for-
ward current at t = 650 C is 15 9mP; the half-wave current pulse is 150 amp; the
temperature rang- is from -650 and 4150OC; the maximum forward voltage drop i-s

0.75 v; the maximum reverse current is 5 milliamp; the maximum control current
for unblocking is 25 milliamP; the maximum control voltage for unblocking is 3 V;
the holding current is 10 milliamp; the forward breakdown voltage (four variants)
is 25, 75, 150 or 300 v. There are 15 figures, 13 tables and 3 Soviet-bloc re-
ferenoes.

speech characteristics obtained by circuits containing Schmidt triggers. Such circuits
separating out threshold speech characteristics can be found in a paper by G. L Tsemell
(Problemy peredachi informatsii, vyp. 18, M. Izd-vo AN SSSR, 1964) who also dis-
cussed optimum speech characteristics. The present paper discusses in conside

Abstract Before and beginning wit.% the 2nd to 14th days after rem-
val of the pancreas (P), cliolinesterase (CE) activity with-
in smooth muscle org-,ns of froas was deterriined. T1,e sto-
mach's muscular layers, abdoridnal aorta tissue, lun,,; pa-
renchyma, and urine bladder were used as specimens f.-)r the
investiLgation. DurinG Uilc fall and winter seasons, CE ac-
tivity was constant in intact animals. It became sharply
intensified in sprinr,, during March and April, and then
a&-iin returned to its initial magnitude. After P was reno-
vcd, CE activity of smooth muscle orCpns became more inten-

Normalization then followed 10-12 days after the opera-
tion. If acetylcholine was introduced to the aninals on
days when CE content deviate%'- most from the norm (6--~tii.
day), CE activity was o-f normal magnitude, or somewhat
lo'w3r. It is assumea that hidier intensity of CE activ~_-
ty is connected with quantitative decreases of acetylelioli-
no which forms within the or_-Anism, and that this plionone-
lion presents one of the c5sential factors responsible for
the Cisruption of parasyrapatlactic and somatic nervous sys-
tem activities in animals w1ioso pancreas has been removed
