Abstract I Casting in jacket-type split moulds is considered one of the progress-
ive foundry processes. The numerous advantages of split mould casting,,
in comparison with the ordinary casting in raw sand forms, are listed.
The requirement for moulding and core materials for such type casting
is reduced by 80%. Split mould casting offers the possibility of cast-
ing thin-walled ob4cats, considerable reduction in machine weight and
metal economy. Graphs; drawings; illustration.

ABSTRACT: NIITAvtoprom (NIITAvtoprom), and its branch in Minsk,
have studied shell-mold casting in the machine building
industry and c&me to the conclusion that its effectiveness
depends largely on special equipment and the level of me-
chanization and automation of the casting process. Among
the equipment suggested, is a mixer for the preparation
of the sand-resin mixture (fig. 1), an automatic machine
for the manufacture of shell half molds (fig. 2), a machine
for the manufacture of shell cores (fig . 3), a high-fre-
quency press for cementing the shell half molds together
(fig. 5), a device for pushing out the castings (fig. 7)
and a setup for the regeneration of the quartz sand (fig.
8). The devices are described in detail and performance
data is given. In the development of the technological

TOPIC TAGS: nitroglycerine powder, powder combustion rate., nitro-

ABSTAACT: The question of how the gaseous phase of burning powder
inflIences the combustion rate-is yet unclear. Therefore, -he

authors undertook testsl burning two thin rectangular plate-s of
nitro:glycerine powder or of pyroxylin separated by a gap of 1 x 10
rwn and sandwiched between two plexiglass plates. The two plates
were placed in a bomb with nitrogen and ignited with black powder.
Burning was recorded on a movie fiLra. I-. was found that when -Lhie
gap was small (it"i width-less than twice the'distance from the
surface to the maximum temperature zone) there was a dec~-,;~.;fn- --ate
of burning as compared to the normal rate-which is by the

PERIODICAL: Avtomobilfnaya promyBhlennost', 1958, Nr 9, pp 19-23 WSR)
ABSTRACT: The heat exchange processes in internal combustion engines
are important for theory, design and exploitation, since 50
to 602o' of the heat generated at fuel combustion takes part
in the heat exchange. But these processes are not suffi-
ciently co.nsidered in engine design and construction. In
order to clarify the character and degree of the influence
of diverse exploitation factors and dimensions of the cylin-
der on the thermal state of its parts, experimental investiga-
tions of the thermal state of pistons and cylinder heads of
3 engines of diverse dimensions were made. The test en-
gines ZIL-121, GAZ-51 and MZMA-401 had the same compression
degree of 6.1. The aluminum cylinder head of the GAZ-51
engine was exchanged for a cast-iron one so that the 3 en-
gines would be uniform. Uniformity of testing and measuring
Card 1/3 equipment was provided. The basic design data of the com-

An Investigation of the Thermal State of Cylinder Heads and Pistons of
Automobile Carburetor Engines
bustion charibers of the engines is tabulated (Table 1). The
mean temperature in each engine was measured at four points
of the piston and the cylinder head (Figure 1). The fixing
depth of the thermocouples in the parts from their surfaces
on the side of the combustion chamber was 1-5 mm with the
ZIL-121, 1.2 mm with the GAZ-51 and 1 mm with the MZMA-401-
The influence of the thermal inertia of the parts was ex-
cluded by.measuring only after a continuous thermal value of
5 minutes. The temperature was determined by the zero
method; in the cylinder heads by aid of an ordinary potentio-
meter, in the pistons by thermocouples with periodical
switching-in. The results are represented in Figures 3-9-
The character of the temperature exchange, depending on the
coefficient of excess air, is the same for all 3 engines.
Evaluation of cooling water influence, inertia of parts at
changed engine operation and diverse dimensions is presented
Card 2/3 by formulae.

pulling germanium monocrystal in the specified way, with p-n junc-
tions the methods reduce to the gro~-m-junction method. A study is
made of the electrical parameters of structures of p+ -n-n+ and
n+ _P_p+ which are indispensable for preparing high sensitivity
devices with carrier-injection in the space-charge region. The dis-
tribution of impurities in the intermediate layer is evaluated by
curves of junction-capacity against potential. Evaluation of the
width of the intermediate layer and the distribution of electric
field in the neighborhood of the locking layer of a p-n junction is
made by potential distribution curves. The specific resistivity of
the germanium in this layer lies in the range 5 to 20-30 ohm.cm.
The width of this layer is about 20-40 microns. FAbstracter's

TEXT: The optimum conditions for growing long dendritic germanium
crystals were studied. The twin structure of real dendrites was deter-
mined and complete agreement was found between the twin structure of needs
and of crystals grown from them. Impurity segregation coefficients and
the distribution of impurities were measured. The dendrites were grown by
the Czochralski method (rate of linear growth 10 - 15 cm/min) and were
150 - 300 thick, 1.5 - 3 an wide and 400 mm long. They were produced
with varyipng impurity concentrations, surface perfection and thickness.
They could be divided into 4 groups according to twinning propertiess
(1) Homogeneous twin structure right aoross; (2) homogeneous twin struc-
ture, but only in the middle of the dendrite; (3) cross-sectional twin

structure but becoming simplified toward the edges; (4) cross-sectional
twin structure which becomes more complex toward the edges; up to 32 twins
were observed at the edges. Sillig's proposition (Act& Metall., 5, No. 1,
1957) that twinning maybe caused by impurities was not confirmed:
impurity concentrations of up to 1020CM-3 caused no additional twinning
effects. However, a higher impurity has an unfavorable influence on the
quality of the dendrites. The segregation coefficients were measured for
In, Ga, Sb, and B in dependence on their concentration in liquid phase.
In each case 5 - 7 measurements wore made in the following ranges of con-
centrations: In:2-10 14 4.10 19 ca-3, Gatl-1014 _ 6-1o 18 em-3, Sb:6_i013
- 2-10 20 cm-3, B:1.1014 4-10 19 cc-3. In, Ga, and Bb show anomalously high
segregation coefficients (K off >1) at concentrations of 1014CM-3, which
fall smoothly with increasing conaentration. At 10 18 - 10 20 Koff of Go
coincides with the equilibrium values K Of B reaches 0-5 at 10 14

impurities was determined from the potential distribution, measured by
