TEXT: The temperature dependences of the coefficient X of heat conduction,
electrical conductivity 6, thermo-emf a, and Hall constant of p-type CdSb
single crystals were measured in the range of 77-4200K. x was measured
with thermocouples in a steady flow of heat (Ye. D. Devyatkova, I. A.
Smirnov. ZhTF, 27, 1944v 1957). At low temperatures heat conduction is
mainly due to the phonon mechanism. This was confirlmed by the hyporbolic
K-versus-T curves. At high temperatures, however, a rise in x of CdSb
single crystals was observed. This appears to be due to the transmission
of infrared light at high temperatures. There are 6 figures Prd 1 table.

ABSTRACT: The author describes how his (unidentified) airport
has automated three of its 4 corridor homing radio-
stations by using the transmitter of its distant
homing radio-station, which, for this purpose, trans-
mits a signal of a certain frequency and duration. This
eliminates the necessity of having an extra transmitter
and secures a high quality of the signal. Then the
author provides a general description of the contents
and functioning of the employed PTU-2 remote control
attachment to the available PAR-? transmitters, illus-
trating it by a block-diagram; he briefly mentions how

A33TRACT: In connection with the problem of switching the operation of
calculating machines from numerical computations to those
denoted by letters, a method is i,eeded to discriminate be-
tween the identically true and false formulae of bivalent
logic, which can be applied automatically by a machine.
For this purpose, a set of algorithms should be found, from
which the optimum algorithm could be chosen for mechanical
performance. The author locked for the rules on the basis
of which various algorithms could be construed for determin-
ing identically true and false formulae of the calculus of
assertion formulae of bivalent logic. He has found five
sets of rules which make it possible to determine this
by means of logical operations of one of the 16 combinations
Card 112 of these operations. The rules are designed for transform-

ation into logarithms which can be used in calculating ma-
chines. These rules differ in a number of peculiarities
from those of the known method of determininr identical
truth or falsity of formulae, and this makes them more
effective for using in calculating machines. There are
2 tables and 2 Soviet references.

CALCULATION OF A TURBINE STAGE (USSR)

A simple method is given for design calculation of a modern high -temperature
aircraft turbine stage with a conical meridional flow and variable inlet param-
eters. The same assumptions are made as in hypothetical cylindrical. flow in
regard to constant heat capacities, radial displacement of the flow line, vari-
ation of the velocity coefficient, and the effect of end losses. Equations are
deduced for the motion of gases in the blade clearance, and parameters are
established for the outlets from the nozzles and the rotor. A calculation method
for checking a turbine stage is also given, by means of which all parameters
can be determined on the basis of the given turbine-stage geometry. [ACI
