ABSTRACT: The object of the investigation, described,'in the present
paper, was to explore the possibility of providing a
protective atmosphere during heat treatment of watch
parts (balance springs) by using titanium hydride as
the source of pure hydrogen. There are two methods
of preparing titanium hydride.vl One consists in heating
metallic titanium in hydrogen to 9000C and cooling it
to room temperature in the same atmosphere.. Diffusion
of hydrogen, slow in the,initial stages of the process,
becomes quiie rapid when cracks have appeared in.the
metal; when the saturationpoint has been reached, a
large quantity of hydrogen becomes adsorbed,on the
surface of the grains, as a result.,of which the Iquantity
Card 1/8 of this gas absorbed by the metal after thistreatment is

higher than that indicated by the stoichiometric.formula
of titanium hydride In the other method, which is more
economical, titanium hydride is obtained by reduction.
of Ti02 with metallic hydrides such as calcium hydride.
It has been postulated that the composition of titanium
hydride is given.by the formula TiHl '-; the TiH2 phase,
richer in ydrogen, has face-centre 8Nic crystal lattice
(a = 4.48 In the absence ofla conclusive proof.of
an existence of a hydride with the formula,TiH?,.it is
probable that this phase consists of TiHl 7 with some
excess of dissolved hydrogen. Titanium -*2ride has
density of 3.912 9/cm-'~., is stable at room temperature,
and not hygroscopic. One volume of titanium can.re.tain
at room temDerature 1800 'volumes of hydrogen; on
heating, most of this hydrogen is liberated but
complete liberation takes place only at relatively
high temperatures (800 to,10000C). The balance,springs
whose heattreatment was,the object.of the present
investigation, are made of-two tWes of-Elimvar alloysi

experiments, the heat treatment of these com-ponents was
carried out at 640 to 7000C, in the protective atmospheres
of town gas, dissociated ammonia, commercial grade
helium, nitrogen, and hydrogen. Although all gases,
were passed through a drying and purifying train, they-
failed to prevent oxidation of the heat-treated parts.
The attempts to heat-treat these components in vacuum were
also unsuccessful; springs, made of alloy N35KhMV,
retained their bright surface but lost,some of their
elasticity, evidently due to the surface layer becoming
depleted of carbon; vacuum heat-treated alloy N4lKhTA
acquired a matt surface, most likely owing to the . ,
precipitation of titanium on the alloy surface; similar
effects were observed,in the case of venadium- and
molybdenum-bearing alloys. In the next stage of the
investigation hydrogen, obtained by dissociation of
titanium hydride, was used (titanium hydride contained
C). The

approximately 10---' mm Hg, sealing it off and heating in

time, no significant quantity of hydrogen is liberated

cooling cycles. Regarding the protective properties
of the atmosphere obtained by this method, it was found
-that to preserve the.bright surface of the created
articles, hydrogen pressure of 3 to 4 kg/cm had to be
attained in the container at the heat-treatment
temperature. Owing to the ability of titanium hydride
to liberate hydrogen on heating, and to re-absorb
it on cooling, one and the same charge of titanium
hydride can be used more than once; it was established,
experimentally, that 8 to 10 g titanium hydride (TiHo)
was sufficient'to heat-treat 12 to 15 batches, each
containing 400 balance springs. In the next series
of ex-Deriments, an attempt was made to produce hydrogen
by dissociation of titanium hydride store it in a

then use it for heat-treatment when necessary.. The parts
to be heat-treated were placed in the container which
was then evacuated filled with the cylinder hydrogen,
sealed off and heated to the required temperature.
Although the pressure in the container at ~he heat-
treatment temperature reached 5 to ? kg/cm , the heat
treated parts became slightly oxidized. It was inferred
that from this that full protection against oxidation
is given only by hydrogen obtained directly from.
titanium hydride. It was also proved, experimentally,.
that when titanium hydride is used to provide-the
protective atmosphere, full protection against oxidation
can be ensured_~y evacuating the container to vacuum no
better than 10 mm Hg. The bright surface,of the
0
heatu-treated components can be preserved even without
preliminary evacuation of the container, but in this
case, three times more titanium hydride have to be
used to ensure favourable ratio of the partial pressure

not less than 2.5. In the last stage of the present
investi-ation, the application of titanium.hydride in
heat-treatment of soft magnetic alloys was studied. A
trial batch of electro-mechanical filter resonators,
in the form of flat plates (6 x 8.5 x 0.2 mm), made of
\~Permendur alloy K5QF2 was placed in the container,.
together with 6 g of titanium hydr de (TiH2). The
container was evacuated to 2 x 1P mm Hg, heated to

.furnace at-the rate of 50OC/h. No evidence of oxidation
was found on the parts treated in this manner, whereas

ABSTRACT, At the Moscow Machine Tool Manufacturing Works
"Krasnyy �,roletariy-', "Imeni A.I.Yefremova'.. a gear
wheel automatic production line, the first in the
world, was set to work in May 1958. The equipment
was constructed by the "Stankokonstruktsiya;'.Works
in Moscow with the collaboration of the following
members of the ENIMS staff, Kup-tsov, A., Abank-in, V.7
Belov, V., Sitnikov, A., Arni., B., Shcherbakov,, V.,
Krukovets, L., Zillbergleyt, V., Kolodnyy, Ya.9 and

sizes was an.essential condition. The line is intended
for the machining of all the gears in the engine and
screw cutting lathe, model lK62, namely 120,000 wheels
per annuin. Ten-different single rim, boars (sketches
and main clim nsions included in Table of the second
grade of accuracy and.noise are in the production
programme. The gears,have outside diameters betweea
88 and 220 mm and modules between 1.75 and 4 mm, Each
batch consists of 1000 components. The time for
re-setting from one wheel to another is 4.5 hours.
The line is serviced by 3 setters among whom the senior
setter is responsible for his shift. A finished gear
is produced, on the average, every 1.5 min. The blank
is a pierced forging obtained in.a mechanical-forging
press after electric rr gas heating. The blank has
undergone induction heat treatment and de-scaling.
The orIgInally projected finish stamping of the gear
faces has not yet proved possible and they are machined
in the production line. The automatic line performs
machining but not flash removals, cleaning or inspection.
Card 2/5 A flash removal machine is being developed. The setters

150 million gear wheels made in the Soviet Union, one
half are single rim. gears.between 90 and 300 mm
diameter producible by an automatic line such as that
described. An electric truck supplies blanks to the
automatic magazine. The blanks are stacked on pins
mounted on a frame which is placed under-the magazine.
A mechanical, arnL lift s a blank from the pin and thereby
begins the cycle of manufacture. The lay-out of the
production line in elevation (Fig~l) illustrates the
Longitudinal horizontal transporter of the bar type.
This moves each component from.the platform.of the
loading and-unloadIng device of each machine to the
platform of the next device. The transporter
reciprocates by hydraulic power attached at the end of
the line. When reciprocating, hinged-flaps either
slide over the components (in the reverse direction)

ABSTRACT: The article gives the results of developing and testing
systems of speed control for diesel units based on :-
a combination of mechanical governor and an electrical.
system that reacts to changes in the electrical load.
The results of investigation are given of a two-pulse
system of speed control for IC,engines marine and steam
turbines which were carried out at the Leningrad
Polytechnical Institute. It is shown that the standard
type of speed governors have a number of.disadvantages
which can be overcome largely by applying a 2-impulse:
regulator which responds to the electrical load Fig.1,
p.20, shows the basic scheme for an additional ;egulator
which responds -to the load of the diesel-driven generator
investigeved at the Automatics and Telemechanles School

of the Leningrad Polytechnical institu-Ie. The funda-
mental part of the regulator is a phase sensitive bridge
fed basically with the system voltage (3-phase) and
introducing into the central conductor a voltage
generated by the load current. If the load is a pure
reactance. the voltage drop across resistance R, in
the neutral lead of the rectifying circuit will.be
shifted by 900 relative to the main voltage u ; the
resulting voltages U3 and U4 fed into the rectifiers
will then be equal and the circuit will be in equili-
brium. As soon as there is an active generator load,
there will be an active component of the voltage drop
across resistance R, and the circuit will no longer.
be In equilibrium and, thereby, the controls will be
actuated. Fig.2, p.21, shows experimentally obtained

The authors recorded the lines of the inner conversion on the
K shells as well as on the L- and X-subshella of the SM152 and
SM154 by means of a prism-p-spectrometer of great resolving ca-
pacity and determined the ratios of the conversion coefficients
at the energies 122 and 123,2 keV of the transitions. The re-
solving capacity of the prism spectrometer used here, was in..~
creased by the following measures: 1) Shielding of the tubes of
the spectrometer against extraneous magnetic fields by iron
rings. 2) The straight gap of the registering device was re-
placed by a slightly.curved gap. 3) A certain nodification of
the feeding of.the magnet and of the lens of the sp*ctroneter.

123,2 keV on the subahelle of the Sm152 and Gd'54. The condi-
tions under which the lines war* obtained as well as the be-

conversion coefficients agree with the here measured ratios.
The M-eubshells of samarium: A further diagram demonstrates
the sphere of the :-spectrum with the lines which are pro-

The authors found the following ratio of the coefficients of
the conversion on the U-subshells: VI:xII :M11I ,1:(3,4+0,1)-.
:(3,3+0,2). This corresponds to the conclusions from the
approximated calculations of the relative conversion coeffi-
cients. Furthermore L/M - 4,5+0,1 (L-L,+L,I+Lllll

TITLE: A Photoelectric Method Used to Discover the Depth
Inhomogeneity of a Semiconductor
PERIODICAL: Fizika tverdogo tela, 1960, Vol,, 2, No- 11, pp~ 2689 2692
TEXT. A knowledge of the depth inhamogeneity of semiconductors is of
importance for a number of problems as, e.g., for the diffusion of
impurities. The authors have developed a method for determining the
"depth dependence" of the carrier lifetime. First, it is shown
theoretically that by studying the frequency dependence of the complex
amplitude of photoconductivity (especially of T efd~ the depth
inhomogeneity of T may be found and studied, for T (w) -,I- are tanip(w)j
eff
where ~(&)) is the phase delay of the photocarriers with respect to the
;exciting light, The theoretical solution of the problem is.restricted to
small gradients of T(z)- For the purpose of experimentally verifying the
above-described rules, some Ge specimens were examined. Fig,! shows T eff(W)

as a getter, The specimens were 1.8 mm thick, the lifetime gradient being
Ld d1nT/dz::L0.2. An inhomogeneous function -r(z) may also easily be
achieved by using specimens in which T depends on the time of exposure.,
by constant unilateral exposure T becomes a function of z~ Fig.2 shows

TEXT: The present paper was read at the 10th All-Union Conference on
Nuclear Spectroscopy, which was held in Moscow from January 19 to
January 2[, 1960. The authors investigated the relative intensities of the
conversion lines by means of a spectrometer with double focusing, a line
half-width of from 0.25-0.35%. and a solid angle of 0.1-0.2%. Lutecium
fraction, which had been separated from a Ta target irradiated with
660-Mev protons was used as a source, Table 1 shows the energies and the
relative intensities of conversion lines in the Yb172 spectrum and the
energies and relative intensities of the ~'-lines, which had been taken
from a paper by Dilman et a!. (Ref. 2). On the basis of these data, the
internal conversion coefficients for a number of transitions were calcu-
lated, and the multiplicities of these transitions could be estimated,

There follows a detailed discussion of these data, and a discussion of
experimental results, which the authors consider to be in need of
improvement, The investigations of the transition energies and the Con-
version electron intensities of yielded rather inexact results,
Partly, the occurrence of a large nu~_ter of weak lines with short half-
lives in the conversion electron spectrum is to blame for this. Table 5
gives the transition eneTgies and the intensities of the conversion lines
of Yb170' the doubtful data being shown in brackets.. A possible variant

TEXT: The present paper was read at the 10th All-Union Conference on
Nuclear Spectroscopyj which was held in Moscow-from J'anugry 1~1 To 171
January Zf, 19W. The converS20n electron spectra of Lu 9 and Lu were
investigated by means of a ~-spectrometer with double focusing, the
relative line width amounted to 0.25-0-35~4. The two sources were obtained
by irradiation of Ta targets with 660.-Mev protons on the synchrocyclotron
of the OIYaI (Joint Institute of Nuclear Research), the Lu fraction was
separated by ion exchange and applied onto an Al foil. As the Lu 169 and
LU170_half-lives are nearly equal, the lines of these isotopes could not be:
separated. Table 1 shows the relative intensities of the conversion lines
