TEYT: Literature data indica-,e the possibility of ohtaining beryltium-
zinc alloys, but there is no information available on the nature of interaction
of these elements and on the properties of their alloys. The authors studied the
nature of interaction of berryllium and zinc at temperatures up to I,OCOOC. Alloys
of these elements were obtained by electrolysis of berryllium-containing melts with
liquid zinc cathode permitting the accurate regulation of the allay composition
and of the rate of supplying one component to the surface of the other one. Alloys
from a molton ohloride bath were obtained in a closed electrolytic cell (Figure 1)
with a molten zino cathode. 1ho olootroLytf) tomperature was 700 + 10oC. Prior to
electrolysis the melt was blown through with dry hydrogen ohkjrldt~. rxt,or tfirmtna-
tLon of the experiment the alloy was cooled either together with the eleetrolyte,

or in air, by pouring the content of the electrolytic cell on a stainless steel
griddle. Thermal decomposition of tile alloy was studied by placing it into an alun-
dum crucible on the bottom of a hi?rmeticaily sealed 2quartz 3tube in a siLlt neating
furnace. At a constant pressure in tile tube of 10 - _ lo- mm Hg, t.t,e temperalure
in the furnace increased at a rate of 3500C per h. After 3 h holding at 1,000 -
1,0500C the unit was cooled down to room temperature. Zino-beryllium alloys were
also prepared by direct alloying of the metals by introducing a piece of beryllium
metal. into the molten zinc at 800 - 8500" and holding for 9 - 70 h. It was found
that at 700 - 9000C beryllium wa.- well wetted with liquid zinc and dissolved in It
in small amounts; tne solubility of zinc in solid beryllium could not be establish-
ed. The experiments proved the possibility of preparing bi-phase Zn-Be alloys by
deposition of beryllium on a liqu.1d zinc cathode from molten salt electrolytes; it
is shown that such alloys are composed of beryllium particles suspended in liquid
zinc. Their fluidity is preserved at a content of up to 6 weight % Be. The ex-
periments on tile chemical and thE'rmal decomposition in a vacuum of zinc-beryllium
alloys show that at over 1,OOOOC Zinc may be entirely sublimatad in a vacuum and
pure beryllium powder may be obtained. There are 6 figures and 9 references: 4

TITLF: The effect of thorium on electrode potentials of bismuth in alkali-

TEXT: To investigate the effect of the cation of a streng complex-forming
salt upon bismuth behavior in alkali metal chloride melts, eqiailibrium potentials
of bismuth were measured in such melts, containing thorium and bismuth, at various
tempc-ratures (950 - 1,100 K). An equimolar mixture of potassii4m and sodium
chlovides with 3.1 weight percent ThC14 and 1.7 weight percent BIC1 was used as
an eLectroly-te. After inelting the mixture wasrefined by electrolysh. The emf
of the cell were measured every 25 - 30 minutes for 6 - 8.5 hours. The electro-
lyte temperature was maintained within 700 - 850*50C. After the experiment the
thorium and bismuth content of the electrolyte were analyzed. For compari-son,
the temperature dependence of a bismuth electrode without TW14, determined pre-

viously, is given. It appears that bismuth potentials in a KC1-NaCl-ThC14-BIC13
melt are by about 80 mv more positive than corresponding values in the same
melts without thorium tetrachloride. The introduction of a strong complex-form-
ing agent,such as thorium affects the interaction of B13+ and Cl- ions, which
becomes weaker. The BIC12 + 2C1 BiC14 equilibrium is shifted to the left.
Consequently the Bi potential in such melts becomes more positive. There is
1 figure.

ABM~ACT: The authors discuss problems in designing low frequency magnetic induction
ro-ceivers. Losses due to the ferromagnetic core of the coils may be calculated from
the known magnetic permeability of the fern3magnetic core. 7wo cases are considered:
Me

the coix! within the frame as well as its internal magnetic field are neglected. In
into account. It iv shown vathematically

that the expected efficiency of the passive coil exceeds 4y many times the value ob-
ta.ned experimentally. On the other hand, the theoretical efficiency of the active
coil is nearly that obtained experimentally. Orig. art. has: 26 fbimulas, 1 figure,

ABSTRACT: A method for determining the critical ratio of length to diameter, (i.e.
relative length) of cylindrical ferromagnetic cores, is discussed with respect to
the design of low frequency magnetic receivers. TT-e critical relative length is
that length at which the specific permeability of the core reaches an asymptotic
value. This value is always smaller than the chosen value of relative length. It
is shown that the cri'tical value can he determined from a formula for the diamagneti-
zation coefficient (which is relative-length dependent) and from the value of

material permeability. The method use:3 the asymptotic valLes of specific permeabil-
ity and leads -to an expression for the critical relative length. Because the re-
sulting equations am in transcendental form, a graphic method of solution must be
employed. For material permeability 1(..tss than l04, an approxination formula has
been derived to replace the graphic method. Orig. art. has. 3 figures, 5 formulas.

late demagnetization coefficients of' such cores. Analytic c-quations used for'solid

equations are graphed to show the relationship bEtween varicus design parameters.
Several examples are c .onsidered where the use of these parimreter-s. is made and the

these on the process cart be studied experimentally by me&-ns of

and fitted with a vacuum rubber sealing. The hood can be raised
or lowered on guides 2 by means of screw 3 and handle 4. A vacuum
is obtained with the aid of pump type RVN of 200 1/min capacity
and a second stage pump type TsV'Yt-1003 of 10C 1/sec: capacity. Va-
cuum of 1 - 10:; mm Hg can be reached and is measured by valve 5
type LT-2 down to jo-3 mm Hg and by an electro-magnetic manometer

ABSTRACT: Specimens of VT1-1 commercir.l-grade tiLanijui were diffusion bonded In a
vacuum of 10-1-10-" tor at a temperature of 650-IOOUC under a specific pressure of
0
-1 25 min and cooled to 100-400C in vacuum.
.1 5 kg/mm2 with a holding time of I-,.
,The results of tension tests showed that the joints bonded in a vacuum of 10-3 tor in j
the 750-950C range under a specific: pressure of 0.2-0.85 kg/mm2 have a tensile
strength of 55-57 kg/mm2, equal to that of the base metal annealed at the respective
bonding temperature. The maximum tensile titrength (00 kg/inm2) was achieved With
bonding in a vacuum of 10-3 tor at 800C under a specific prensure of 0.7 kg/nM2'
ia holding time of B-10 min, and cooling to 200C in vacuum. The strength of the
Ijoint is determined mainly by the specific I '3ressure and temperature of the bonding
1process. Generally, the specific pressure is 60-70% of the yield strength atithe

,use in other countries as well as the Rumanian equipment with
...which the masts would be used in Rumania and analyzes the
design, operation, yield and safety of some variants of 53-
