ABSTRACT: The mechanical properties of large-scale thin-walled castings used as
panels were investigated at the MVTU foundry. Sample panels, 370 mm bY 35 mm,
and 4 to 1.5 mm in thickness, were cast from various aluminum aW magnesium
alloys (e.g. AI2, A14, AS15, ML15, etc.). Before pouring the k4terial ', the mold
was covered by hexachloroethane (C2C16) for aluminum alloys and with acetylene
carbon black for the ML15 alloy. The aluminum alloy specimens had a strength
with P2 the GOST 2685-55 standard.

ACCMSION NRt AP4030361
Lowering the specimen thickness to below 2 mm revealed a definite reduction In
mechnical properties of the cast. The microstructure of the panels showed no
observable effects caused by minimum or maximum superheat conditions. However., there
was a noticeagle increase in nonuniform porosity for very thin-walled specimens cast
from V15 and AL19 alloys. There was considerable scatter in the measured strength
of various specimens, caused primarily by a nonuniform temperature distribution in
the casting during the pouring of the alloy in the mold. It is shown that the melt
temperature distribution in the mold, the method of pouring the melt 'in the mold,
and the method of feeding the alloy during the hardedning process are'significant
factors contributing to the nonuniformity between specimens and within the given
specimen itself. A detailed comparison is made between casting in sandstone molds
and a pressing-out methos to enhance uniform temperature distritutions in the
molten alloy. In general, the two methods yield similar data scatter in the
strength of the casting. Orig. art. has: 7 figures

ABSTRACT: The authors consider defects of a gaseous origin In thin-walled large-
size panel-type castings with a body thickness of 2.5 - 3 mm and a surface area
of up to 2 square meters. Such defects are conditionally divided into three
groups: gas-shrinkage porosity, gas blisters In the body of the casting, and
gas hollows or depressions on the surface. The Importance of the degassing of the
alloys (normally aluminum and manganese) of which these castings are generally
manufactured Is discussed, and techniques which may be used for this purpose are
described. The relationship of the process of filling and ventilating the sand
mold to the formation of gas defects in thfn-walled panel-type castings when the
latter/ire poured Into such molds, is analyzed. The failure of efforts to remove

the gas and air from the cavity of the mold by Improving the gas-permeability of
the mold mixture Is discussed on the basis of certain experlments which were car-
ried out along these lines. The technique of cutting escape channels along the
joining plane of both half-sections of the mold, In order to provide an escape
passaqe for the gases and air, is considered by the authors to be a reasonably
effective procedure. The use of various special coverings on the mold surface In
order to secure improved filling qualities (hexachlorethane aad acetylene black,
In particular) Is analyzed and experimental results are given. Certain other
chemical solvents are also discussed in this connection. The authors consider the
difficultl3s encountered In pouring thin-walled castings whose design Incorporates
bosses and fluted sections Into sand-clay molds because of the Increased danger of
the formation of gas-originated defects. Controlled temperature conditions during
the filling of the mold are recommended In this case. Problems arising EPROM the
Improper position of the casting In the mold and Improper design of the o1old It-
self are discussed as they relate to the type of defect under consideration when
squeeze-pouring panel-type castings. Attention Is also called to the IIM)ortance of
the correct selection of the die for the metallic half-forms of the mold, when
pouring thin-walled castings by the extrusion method, since In many cases this may
,be the direct cause of the formation of gas defects on the casting surfa:e and a
source of gas saturation of the metal. IlEn Ineer L. P. Kashlrtsey-took part In the

The authors assumed that a reduction of chlorine to HC1 takes place,

TITLE. Mobility of catalyst modifying additives introduced
into silver catalyst
PERIODICAL: Kinetika i kataliz, v.2, no-5, ig6i, 684-689
TEXT: The activity of many catalysts can be profoundly modified
by the presence of even minute quantities of various elements or
compounds and especially of halides. Because the selectivity of
the catalytic action of pure silver in the synthesis of ethylene
oxide is usually very low, it was thought desirable to investigate
the effect of various catalyst-modifying additives on the
selectivity of silver in the above reaction. The investigation
was based on the use of tracer technique, in which the radio-
isotopes C136 '1131 and s35 were introduced as chloride, iodide or
sulphate ions into pure silver catalyst. Pellets of the modified
silver catalysts were heated in a stream of reactants and the
mobility of the additive substances were determined from changes in
the radioactivity counts. Preliminary tests showed that silver
chloride, silver iodide and silver sulphate formed during the

reactions were present on the surface of the catalyst pellCts only.
The tests were made in a stream of nitrogen, air and a
35'0' ethylene/air mixture, the reaction time being up to 5 hours.
The results showed that the catalyst additives are progressively
reduced during the reaction and removed from the silver catalyst
surface which, in the authors' opinion, may be responsible for the
low selectivity of the catalyst in the synthesis of ethylene oxidle.
Similar results were obtained in tests with iodide and sulphate
tracers, An increase of the reaction temperature and the use uf
higher concentrations of the reactant were found to favour the
process of additive reduction and thereby diminish the catalyst*.-,

ABSTRACT: Mie results of an experimental investigation of diffuser grates are pre-
sented for strongly curved (by 600) profiles with different density and
at small angle of Incidence (t 50). The effects of the roughnes's, of the
Reynolds number and of the relative aspect ratio on the efficiency of the
diffuser grate are considered. The performed Investigation has shown the
possibility of applying diffuser grates made of strongly curved profiles
to axial engines.

TITLE Extending the region of stable operation of an axial
~,ompressor stage
PERIODICAL: Teploenergetika, no.2, 1962, 41-44
TEXT~ A typical form of instability in axial compressors
operating at low speeds is the formation of rotating zones of
breakaway of fluid from the blades, These zones of breakaway
usually begin only at the blade roots or tips but ircrease as the
amount, of throttling is increased and, at -very low rates offlow,
may :over the entire blade length. In multi-stage axial
compressors running below the rated speed, critical angles of
incidence occur mainly on the first stages or on stages immediately
beyond air bleeding points. Total breakaway may occur on a few
stages but may sometimes occur on all with great loss of efficiency.
The trouble can be overcome by increasing the flow through the early
stages but this is wasteful. Attention to blade design cannot

give muh improvement, Theoretical investigations of the stability
of an axially symmetrical flow indicate that when stability is lost~
flow may take one of two formag with the formation of rotating
zones of breakaway, or with an axially symmetrical annular zcne
of breakaway, or annular swirl, associated with the occurrence of
a counter flow, The relative stabilities of these two kinds of
flow vary ac.:~ording to circumstances but, by promoting annular
swirl. it is in principle possible to prevent completely the
formation of rotating zones of breakaway. Tests were made with
compressor stages in which various measures had been taken to
promote annular swirl., namely, cutting annular slots in the casing
just ahead of and just beyond the tips of the blades-, installing
an annular step or ridge in the casing just in front of the ring of
blades, also, blowing air into an annular slat located just ahead
of the blades, All of thecae measures were found to extend the
zone of stable operationj however, the most convenient and
structurally simple is that of blowing air through an annular slot,
With this stage, tested when air was blown in at a head two or
three times greater than that of the 5tage, the boundary of stable

OUtpUt,5 and the maximum energy of pulsation in the zone of
breakaway was reduced by 40%. The amount of air blown in was about
2.5% of the minimum flow necessary to ensure stable operation,
Additional. tests have shown that the effect of blowing in air in
thI5 way differs for the different stages, There are 6 figures and

ABSTRAM This Author Certificate presents a genrator-vector meter for determining th
amplitude-phase frequency characteristics (AFCKKH) of quad ipoles. The device contain
an infralow frequency generator (for producing two 900 phase-shifted voltages) and a
ferrodynamic system vector meter. It is designed to make possible the use of the
device for determining the AFCHKK in the lower part of the infralow frequencies by
measuring the instantaneous values of the amplitude and phase of the signals. The
vector meter is provided with a sliding system which has a small moment of inertia and
a large opposing moment. The vector meter in also provided with an air damper with a
small damping coefficient, and with flat extensions for insuring two-dizerAianal
freedom of the sliding system and for producing the opposing moment. In order to

ABSTRACT: The problem of the abrasive and piercing effects of micrometeoritic col-
lisions with spaceships and satellites is investigated. The dependence of the ratio
of maximum penetrable barrier thickness to the depth of the crater on the velocity
of collision is analyzed. On the basis of experimental determination of several of
the physical parameters involved in the theoretical estimates, the maximum penetrable
thicknesses are computed for several particle-barrier pairs for collision velocities
of 1UlOO km-sec-1. The problem of the penetration of several barriers by a nonde-
forming particle is examined, and, after certain assumptions are'made, the penetra:-
tion of a second barrier by a deformed particle and stream of fragments is evaluated.
On the basis of the solution obtained and information gathered from rocket and satel-
lite flighW, an estimate is made of the rate of annual surface abrasion resulting
from collisions with meteoric particles at various heights above the earth.' Re- F

lying heavily on the findings of Wursthorn, Whipple, and Fireman, the author con-
cludes that a layer of aluminum shielding having a thickness of 0.22 mkm, such as
was used on Echo 1, remains intact for at least one year. The maximum annual wear
of the aluminum surface at a height of 2000 km does not exceed 1.6.10~3 mkm. It is
noted that the return to earth from space of specimens of materials with known prop-
erties that had been subjected to micrometeoritic bombardment helps in establishing
the dust spectrum with respect to mass and velocity. Orig. art. has: 30 formulas,

ABSTRACT: The author notes that a unique solution to the prob lern of the steady-state
movement of a viscous liquid In a certain volume Is possible onli If the boun
y
on the surface limiting the given volume are known. Since the boundary conditions are
conditioned by the very form of the movement, the problem loses its specificity. In many.1
cases, the boundary conditions are not given completely, and an infinite number of math-
ematically equivalent forms of movement may be realized within the volume of liquid con-
sidered. In order to approximate the actually existing form. It becomes essential either to
postulate additional suppositions or to apply some criteiria which make It possible to select;_~

realized. Variational principles of maximum consum~ption, maximal flow of meci-tanical
energy, its minimum dissipation, etc. are occasionally employed as ouch criteria. In
recent years, the author has conducted studies Into the variational criteria of stability
with respect to turbomachines. 11iis research has resulted in the establishment of the
principle of the maximum flow of mechanical energy. Its application, as well as the use
of a particular case - the minimum dissipation of mechanical energy - permits a new
approach to the study of the movement In the flow-through section of turbines under all op-
erating condlUons( including non- steady-state modes). By way of example, in the present
article, the author considers the possibility of applying the principle of the minimum
dissipation of mechanical energy to the solution of the problem of the equalizing action of a
grid located In a stream with regular non-uniformity. In the solution (See Figure 1. of the
Enclosure), it was assumed that there are no tangential stresses beEween the jets and
between the jets and the walls as the liquid travels in the tube at different speeds. The
following parameters were considered constant: 1. the static pressures in the tube
sections located far in advance and behind the lattice array; 2. the axial velocities for the.
section of each current tubing, in view of the smaU initial non-uniformity and the smallness -
of the transverse velocities In comparison with the axial; 3. the resistance factor of the

ABSTRACT: For second order systems with vai7ing load moment and a number
or limitations (on moment and motor speed),, it is shown to be possible to
work out fixed displacements in regimes near optimal. A method is presented,
for evaluation of the error of the process and selection of a motor with
these control procodures. The control process selected utilizes linear
i~orrection of path or movement time to produce the required displacement of
,the controlled object in minimal time with maximal accuracy,, under condi-

PERIODICAL: Mashinostroitell, 1958, # 2, P 32-33 (USSR)
ABSTRACT: This special face mill, devised b# N.P. Rubtsov, is designed
for cutting teeth on self-centering three-Jaw chucks of machine
tools. The mill is to be used on lathes. It will be fixed In
tfie lathe spindle ("Alirl-200" or "AH-300 11 -Inthe), and the
Jaw to be cut will be clamped in the tool-holder. The upper
saddle will be set for full Jaw tooth height, the spindle
switched on low speed (12 to 20 rpm).
After the mill has passed the entire Jaw blank, the Jaw
teeth are ready cut and relieved.
The mill increases the efficiency of the operation by more
than 400 %, improves the jaws'self-centering accuracy, and
increases the life of jaws.

ABSTRACT: Following a suggestion made by the manager of the oxygen station
of the "Kamsomolets" machine-building plant of Tambov, the attempt
was made to increase production figures by increasing the number
of revolutions of the apparatus. For this purpose the driving disk
of 370 usn diameter on the electromotor w&s exchanged for one
having a diameter of 407 mm. In this way the compressors performed
440-444 revs. per minute instead of the f9mer 398-402 revs.
Originally, the compressor supplied 180 nP/h air; pressure in the
heat exchanger amounted to 100 qtm. excess pressure and the out-
put of the apparatus rzas - 30 m-~/h. Under the new cond3.tions the
compressor supplied 200 m3/h air, pressure in the appamtus was
reduced to 50-55 atm. excess pressure, and the output of the appa-
ratus increased to 34-35 m3/h oxygen. Also the time needed for
starting the apparatus became shorter. Such a KG -30 forced type

where weed 6Towth was studied. The descriptions of the
sites and slopes included cora?utations of the amount
of shoots of the cultivated plants, the floristics of
the weeds taking account of their altitude, story,
abundance and phenological conditions, with a calcula-
tion of the weed stems. On the basis of this data the
weeds were divided into three Croups:
1. The broadly adaptable species which are encountered
equally at all relief elenents.
2. The mesophytics, adapted to depressions in the relief.
3. The species which are abundant at mininal mi3tiwo
at heightened relief elements. The coefficients of on-
k counterability were computed for the last two groupG of
weeds as well as the percentage of weed choking at -~"-hc
various relief elements. On the convex slope: the
watershed had 10.6%, the top of the slope 26.9%, the mid-
Ole of the slope 47.4, the bottom part of the slope -16%;

weed development appeared as an indicator of the capaci-
ty to seed production) and moreover the seed washout
with higher relief was adapted to the depression, since
the weed choking is hi&%er in the depressions. The ef-
fect of relief on the yield of cultivated plants was
seen in a reduced harvest from the watershed dowmmrds
to the convex slopes and an increased harvest to the
bottom part of the slope with a hiGh index for the val-

partly differ considerably. Whereas, eag.v according to

K, but he also showed that in some BiPt-alloys supercon-

ductivity does not occur down to 1,3 0K (Refs 293), As shown
by reference 4t BiPt crystallizes only in one form viz. hexa-
gonally with the parameters a - 4.20 and c - 5.55 1 (NiAs-struc-
ture). Radiographical investigations carried out by the authors
of this "Letter to the Editor" gave the same result. Tempera-
ture investigations also showed that it crystallizes in NiAs-
structure; and the thermal expansion coefficients (parallel and
perpendicular to the hexagonal axis) were determined as amount-

On the Problem of the Superconductivity of the SOV/56-37--3-55/62
-Compound BiPt
The authors investigated several BiPt-alloys of different com-
position also stoichiometrical ones, and subjected them to
different types of thermal treatment. It was, however, found
again that in all cases the BiPt-phase in an AsNi-structure
crystallizes, and the lattice parameters were determined as
amounting to a - 4.315 and c - 5.490 4 0-005 k. The alloys
were investigated radiographically ty means of the powder meth-
od, and the maximum change of the volume of an elementary cell
was found to amount to -0.8% as against the 3toichiometric com-
position (48.3% by weight Pt). This reduction of the elementary
cell was found at 45-/. by weight Pt. The change of the size of
the elementary cell and the herewith connected variation of the
distance between two Bi-atoms might be responsible for the va-
riation of Tc ; already in a previous paper (Ref 7) it was shown
that a decrease of the minimum interatomic Bi-Bi distances
leads to an increase of T . The authors thank Professor
