Thermal treatment in a laboratory cracking unit of continuous operation at 300-5000 and 30 atmospheres pressure, was applied to the 205-2940 and 276-3650 fractions of Tuymazinsk Devonian petroleum and this petroleum as such containing 1-787% sulfur.

It was shown that antigens with different periods of acetylation are insoluble in water, not toxic, Card 11.2 /141croblcl.gy Microbes Pathcg&1jjc to and Animals Abs jOur, Referat, Zh.

These CI reduce the rate of corrosion of ferrous metals by 70 - 95 % and of tin brass ~y 90416VIu. At present sulfosodium salts' of shale tar and nitrogenous petroleum compounds are the most available CI. Introducing ammonia up to pH 7 - 9 reduces the CI condumption to 1/10 - 1/20. Data are given on the rate of corrosion of various metals in the condensation system of an atmospheric-vacuum pipe still during the processing of Tuymazino oil and on tae efficiency achieved as a result of CI introduc- tion. A particularly sharp fall in corrosion was found for Al, for which 99 ~ protection was obtained. LAbstracter's notes Complete translation.] Card 1/1 SHATTIOVA, A.M.) SAPOZHNIKOVA, Ye.A.

The .static magnetic properties, the magnetie'viscosity, and the electric properties of these garnets were previously investigated by one- of the authors (Yefimov Abstract of Candidaie"s Dissertation MGU, 1962). The dynamic hysteresis loop was displayed on an oscilloscope screen at a frequency of 50 cPso using a type Y-542 ferrometer, Plots are presented of.the temperature dependence ofthe coercive force and oscillograms of Card 1/2 L 29299-66 ACC NRt AP601245,3 the hystiarOsis loops are given for the limit cycle of YIG at dIfferent temperatur0s.

Below 12'jK instabilities of the reversal of magnetizat~,on appear on the hysteresis loop.. Withfurtber decrease in temperature, the degree of squareness of the hysteresis loop increases. The perndnTrar effect appears at temperatures below approximately 140K. In the case of high resistance garnets, the coercive force increases slightly with decreasing temperature from 273 to 78K.

TITLE: Temperature dependence of static magnetic and electrical properties of some garnet-type ferrites PERIODICAL: Fizika tverdogo tela, v. 4, no. 2, 1962, 361-365 TEXT: The temperature dependences of coercive force, H residual induction, B., magnetic permeability,)x, and differential magnetic permeability, Ad , of garnet.type Dy, Ho, Er, Tu, Y, and Lu ferrites was measured, and the electrical conductivity of Er, Tu and Y garnets. The specimens, whose size and production technology have been given earlier (R. V. Telesnin, A. M. Ovchinnikova. VMU, ser. 111, 1, 1961) were of almost X-ray density and had very high electrical resistivity, From the results, which are shown graphically, it can be seen that in Dy, Ho and Er ferrite-garnets H c, Br' JAmax and N behave typically near the max compensation point. All theae parameters have a zero minimum at this Card 1/3 A225 S/18 62/004/002/008/05~, Temperature dependence of static... B102YB138 point, H c has peaks on both sides of this minimum. At this compensation point (which is e.g. for 5Fe 203*3DY203 at 2100K) the hysteresis loop is a straight line, crossing the origin. This degeneracy was observed not only with the ballistic apparatus but also with an oscilloscope (500 cPs)~ Electrical volume resistivity was measured on a MOM-4 (MOM-4) device for R,>106 ohm~cm, and with a d-c MT8 (MTV) bridge for R 410 6ohm-cm. The specimens were in a cryostat (constancy of + 20). The curves logQ = f(I/T) were linear with a break at the Curie point for Er and Tu ferrite-garnets., Ye. A. Turov and Yu. P. Irkhin (FMM, 1, 9, 1959) have obtained the same results. This break is attributed to the exchange interaction of inner and outer electrons; the variation Ln inclination is proportional to the exchange interaction energy, Such breaks were observed not only at Curle point, but also at 3480K for Er and Tu, and 3230K for Y, garnets, At low temperatures the activation energy calculated from the inclination was 0.27 ev for Er and Y garnets; at high temperatures it was 1.6 ev (Y), 1~61 ev (Er) and 1.3 ev (Tu). I., I. Mirer took X-ray diffraction pictures of the ferrite-garnets investigated, and determined the lattice con3tants.

The rheobase and the chronaxie were measured 30 min after irradiation. The receptors in- vestigated were either irradiated or nonirradiated, the latter being in functional.connection with the organs irradiated, or not. While the results for the threshold of susceptibility were inconclusive, the chronaxie wa:s always reduced after irradiation.'-~,' This reduction was approximately symmetric and amounted to 59.5ff/z max'~'-in the irradiated zones. The lowest values were observed for the optical chronaxie (13-7 and 20%). Since the chronaxie'reflecte the functional state not only of the nerve itself but also of the centers of.the nervous system, its reduction in nonirradiated Card 1/2 6/24 62/000/011/002/005 Early chronaxie changes of...

Expressed ir. terms of quantum meahanios this means that the mo- dulated amplitude of the wave function of electrons moving in the conduction zone attains its maximum values near nodes occu- pied by positive ions, while its lowest are attained near the negatively charged nodes. For holes in a nearly completely fill- ed zone the opposite is the case. Therefore electron mobility is considerably reduced by the distortions of the "positive sub- lattice", and hole mobility is considerably reduced by those of the "negative sublattice".

TITLEg On the Scq~ttering Mechanism of Carriers in Some Solid Solutionsv~ on the Basis of Lead- and Bismuth Telf~r_ides PERIODICAL: Fizika tverdogo tela, 1959, Vol 1, Nr 9, Pp 1325 - 13,32 (USSR) ABSTRLCT: The present paper supplies a store of experimental material concerning the relation between mobility of electrons.and holes on the one handp and the composition of various lead- tellurium and bismuth-tellurium alloys on the other. The first part of the paper deals with the dependence of the free-path time of electrons and holes on the position of the impurity atoms in the lattice. Following suggestions by A. V. loffe and the scattering of neutral impurities was investigated with the aim of increasing the efficiency of thermocouples. The results obtained by several previous investigations on this subject are briefly discussed and next, the mobility-to-Gomposition curves of the systems Bi 2 Te 3-Sb2Te,, Card 1/4 q 67383 On the Scattering Mechanism of Carriers in Some Solid SOV/181-1-9-1/31 Solutions on the Basij of Lead- and Bismuth Tellurides Bi 2Te 3-Bi2s39 and PbTe-PbSe (Figs 1-3) are dealt with. The abscissa is given by the concentration (in atom%) of thf. second component, while the ordinate is given by the mobility of holes (Curve 1) and electrons (Curve 2). In the first case, the hole mobility rises with concentrationg whereas the elec- tron mobility drops; in the second case, the hole mobility drops, while the electron mobility.remains about constant, In.the third case, finall y, the two mobility curves have a flat minimum at about 50'P~' PbSe. This is indicative of the fact that electrons move toward the cation sublattice, and the holes toward the anion sublattice. The relation be'~'ween mobility and composition in thi; Pyatoffin B1 2To 3-111201) (Fig. 4) and PbTe-SnIle (Fig 5) is more complicated, In the first cage both curves have a minimum, in the second case the hole mobility has a minimum with low SnTe-concentration and there- upon rises steeply, while the electron mobility drops monottin- ously. The electron mobility in biamuth telluride in about four times lees than in bismuth selonide, and the hole mobil- Card 2/4 1 - 67383 On the Scattering Mechanism of Carriers in Some ~0'1'id SOV/181-1-9-1/31 Solutions on the Basis of Lead- and Bismuth Tellurides ity in Bi Te is by the 1.5 fold less than in Bi Se Condit- , 2 3 2 Y ions in PbTe-SnTe (Fig 5) are even more complicated. The hole mobility rises after a minimum, while the electron mobility drops after a maximum. In a similar manner, the second part of the paper investigates the dependence of the free-path time on the carrier energy. A number of diagrams afe shown and dis- cussed. Thus, figure 7 shows the-temperatur'e dependence of mobility for pure PbTe and for PbTe + 5% PbSe with equal carrier concentration (n - 4 1.1019); figure 8 shows the temper- ature dependence ofVn.i.
