ABSTRACT., --This p~a_ r Is; devoted to the, results of the measurement~of the thermal conduct-
ivity and specific heaAlf molybdenum at high temperature,4 (10W-2000K), 'and to the values
of heat __Uu_ s. This or
con HIM75`6tained from the result w ~%ts part of the program of investiga-
tions of the thermal properties of solid and liquid metals- being conducted at the Chair of
Molecular n:s1cs, Pkvsi s DTartment, MGU (kafedr olekulyarnoy fizEd fizicheskogo
fakullteta MGU). The experimental set-up, the methods used, and the specimens are describ-
ed. The values of the heat conductivity of molybdenum and density are presented in graphs to-
gether with the data of other authors. The values of the Lorentz num determined from tha
heat conductivity val S, monotonically decreasing with a rise in temperature from 3.17*yol`~W
1at 1000K to 2. 88- 1 7 j~'e2000K. The appreciable difference of the ]Wrentz number from
the theoretical va:lue 2.45* ir v/dee- testifies to the presence in the molybdenum, of a consid-
erable lattice heat conductivity, amounting to about 15-20% of the electrotlAc. The absolute
-value-of the lattice heat conductivity decreases with a rise In temperature as I/T

examined. It is pointed out, in particular, that tacheometrical surveyirg can
be used .5uccessfully-for drawing up planning projects concerning the kolkhoz
and :.-ovkhoz ecianomic centers and for determining drainage areas in the constru

P-nd the order -of the observations-in'main tacheometrical traverses and in
determining picket points is described. The requirements set on tacheometrical

ABSTRAC'n. A description is presented of the results of investigations
conducted for the purpose of developing a rational procedure,
for extracting Au from the ore. It is established that the most
efficient method with this ore is cyanidation, permitting recov-
ery of up to 9576 of the Au. Two methods of crushing the ore
before cyanidization are suggested: 1) a method involving
washing oi the fines before the second crushing and delivery
thereof to a pulverizing cycle, and 2) a method employing a
rod mill instead of a cone crusher for stage 2 crushing, fol-
lowed by a pulverizing cycle. The possibility of using the sol-
titions after cyanidation (after they have been deoxidized and the
gold has been precipitated) to treat subsequent portions of the

of the kinetics of the accumulation of Cu in return solutions and of the de&ndence
of the -Cu-concentration on the quantity-of return solution. Calculations show
that it is possible to make use of cyanidation return solutions, as the con-

TITLE: 'Indoor Public_-Addresa Systems (Zwk0ftatkya pomeahchieniy)
-PERIODICAL: Radio, 1957, Nr 3, pp 47-50 (USSR)
ABSTRACT: - Public-address systems.in rooms, and halls. find increasingly wide ap-
plication. For good performance of a-public -address system, high-quality-
equipment, accurate observance of technical requirements, and allowance for
acoustic pecularities of the hall are necessary. Practical problems of choice
and placement of equipment in a hall are discussed in the article. Microphones Vith
.1da:Lfordt frequency response are desirable as they are less liable to acoustic
.feedback. Also, a directional pattern and a low sensitivity are desirable. Al-
-though the Soviet-make electrodynamic type SDM microphone can function tuider
-widely variable temperature, humidity'and mechanical -shock conditions, it is
hardly suitable for indoor usage as its frequency response is irregular within
_2100 - 3. 000 - cps, it ha--q an omnidirectional -characteristic, and an 025 mv/bar
sensitivity. Other electrodynamic microphones, e.g., MD-30, may have bet-
ter characteristics, but they area still unsuitable for indoor service Band,
Card 1/4

107-5711:3-51/64
Microphones ML- 10 -and ML. 10B have a much, better frequency response.
They have a figure-eight directional characteristic and are not so sensitive as
the electrodynamic types. Their tendency to accentuate lower frequencies can
be. easily corrected in',the amplifier section. The most suitable for indoor
public-addreIme application Is the 10-A'I microphone, which has a cardiod di-
ret.-tional characteristic andAn adequate frequency response. The performance
