In the 30 examples examined (for segments of declining and rising free seepage sur- face and for the case of a rising slope of the impervious foundation), which com- prise the more typical actually possible cases, the divergence of the results con- stitutes less than 30/6; only for i I = 30 m does it attain 5~6. It is demonstrated that the inconsistencies between the results obtained by the methods of N. N. Pavlovskiy and Chzhan Chzhun-in' would remain of the same -magnitude for any ground-water flow with the same permeability coefficients, the same flow thick- nesses, and the same values of the product i I (the elevation of the high point ofthe impervious'foun*fttion above its low poind A methodical refinement of the con- struction of the line of seepage according to the Chzhan Chzhun-inl method is proposed. An analysis is performed of the relative differences of the results obtained by means of the approximate formula of G. N.

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.

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).

Therefore, -he u 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.

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- SOV-113-58-0.1-8/19 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.

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.

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 Card 1/3 33340 S/181/62/004/001/006/052 Pecubsrities in the growth... B102/B138 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.
