For the purpose of excludinE tne error arising by this effect (which becomes considerable near Curie point), measurements are not carried out immediate- ly after the application of the field (adiabatic measurement), but only some time later. when the temperalure equilibrium between specimen and the surroundin6 medium has been est-!%blia5ied (Isot~lermal measurerner.''

It is now shown that the conclusions drawn by Zaveta are incorrect. TIE' paper by Zaveta (FTT, 2, 106, 19bU) is first discussed in detail, '-or trie change in state 6ue to applyin6 the field. Zaveta gave tfl~e fulliwing formula: IR/R = aH 2/5 + bH; fiere the first term makes tne contribution of the "true" galvanomagnetic effec,, and the second makes tne contribution of the "wrong" galvanomagnetic effect.

Current is regulated by a liquid rheostat and a high current transformer.(Figure 1). The current density A is calculated from A = I/st , where I is the current, s the feed in mm/rev and t the depth of cut in mm. Tests were made, cutting 18KhGT steel at 100 to 300 m/min with s from 0.07 to 0.29 mm/rev and t from 1 to 3 mm. Maximum tool life is obtained only with optimum current density which will vary with cutting speed. At 150 m/min, A was 120 A/mm and at 2 150 - 300 m/min, A was 6OA/mm Figure 2 shows the micro-roughness (microns) of the surface against speed and against feed for various current densities.

The ingots with a diameter of 300-40C mm and a length of 1,000 - 1,rCIC mm are stripped on special turning lathes by cutters made from steel R18 with a cutting speed of 3-5 m/min and abundant cool- ing. As a lubricating and cooling licuid, a water solution of 10 % emulsol and 15 1/c kerosene is used. If the surply of cool- ing liquid stops for a moment, the cutter is heated and gets out of order (Figure 1). The mechanical processing of heAt- resistant steels is very difficult because of structural changes during plastic deformations and their low heat con- ductivity. The ingots have a hard casting skin on the siirface and slag inclosures at a depth of 20-30 mm with hifr~i abrasivp properties. In order to increase the productivity of the work and the resistance of the cutters, a special construction Card 1/2 (Figure 2) has been developed. The steel used in the cutters A Cutter for the Stripping of Ingots of Heat-Resisting Steel SOV-1 17-r P-8-12/28 is RK15.

For evaluation of the wear the method of radioactive isotopes was used. The investigations were carried out by means of a counting- rate meter developed by the author, which enables a -apid determination of small changes in the wear of the LZ ring A schematic diagram of the apparatus is given. Diagrams showing the dependence of the weai of the upper compression ring according to its height on the engines' load for different advancement angles of fuel injection, on the number of turns of the crank-shaft and on the temperature of the exhaust gases are included There are 4 figures.

A study was made of the topography of the basen~ent in order to find large out croppings and structures of the subsalt stratum and upheavals of the platform type.' The seismological characteristics of the region are presented. The cord I / 3 UDC: 550. 834. 3 ACC NR: AR7001772 methodology of refraction correlation observations 'consisted in a continuoi.~.s longitudinal profiling with a system of counter and overtaking hodographs, wh-,Cn ensured a complete correlation of reference waves, and also in a nonlongitudinal profiling, used only for mapping of the basement relief. In longitudinal profiling, each 5. 7 and 11. 4 km long station was surveyed from 13-15-21 explosion points. The hodographs were 30 km long and in the area of tracking of the refracted wave, they were 70 km long. On nonlongitudinal profiles, the station was 11. 4 km long, and the distance from the explosion point to the profile (on the perpendicular) was 50-60 krn. Waves were recorded by SPEN-1 seismographs (100 m from each i other) and a 60 channel PSL-l refraction correlation station with a filtralLion opening toward Hr, and with a steep right cut of the 27-cps frequency curve. Or-, the territory of the traiis-Volga area or Saratov, four main waves were found:- Ti from the surface of the salt; T from th -2 subsalt bed to the depression; T -Irorr, t h e 2 3 surface of the basement (?); T4 from the interface in the thickness of the basement [SIC]. Structural diagrams over two horizons were composed: The surface of the carbonaceous sediments of Lower Permian age, which has a monoclynal dip to the South and the South East toward the Caspian depression; the surface of the basement, characterized by a rather sharp dislocation with a general dip to the C.,d 2 / 3 ACC NR* AR7001772 South. On the whole, the outer part of the border zone shows an irregular dip of the basement toward the Caspian depression, while the inner part is a salt dome tectonic formation. T. Polyakova.
