These methods are based on thermal and optical quenching of the photocurrent. They enable all the parameters of r-centers in CdS, CdSe, and partially Card 1/2 L 20396-66 ACC NR: AP5022470 Cd(S, Se) to be determined. These parameters include the concentra- tion and energy centers, and their cross sections for electron and hole capture. The method also gives the cross sections for absorption and photons with energies of 0.9 and 1.4 eV, these photons trans- ferring a hole from an r-center to an excited level, and to the valence band, respectively. The occupation of r-centers by holes under weak illumination and the probabilities of hole capture by r- and s-centers can be obtained. The experiments for determining the parameters of r-centers were carkied out and discussed by the authors! together with their collaborators Lubtchenko, A. V. (CdS) and Gorodetsky, I. Ya. and Yermolovich, I. B. (CdSe). The authors wi sh to thank them greatly. -Urig. art. 15-as: 5 figures,-,19 formulas and 1 table.

Since the earlier investigations were confined to homogeneous semiconductors, 'the authqrs investigate rd -Ca V2 'lag L 18764-66 ACC NR: Ap6oo3775 the magnitude and spectrum of the noise and the pbotoresponse spectra in single-crystal CdS containing inbomogeneities at frequencies I 4000 cps. A simultaneous study was made of the distribution of the optical resistance and the relaxation times of the photocurrent along the samples. In some samples the inhomogeneities of resistance were introduced artificially. The photosensitive CdS single crystals were ,produced by several methods, and were illuminated weakly with light of wavelength -520 or ~,630 nm from which the infrared component was cut out. Most measurements were made at room temperature and in air,-,', although some were made in vacuum and at other temperatures. The spectral-measurement apparatus was described elsewhere (UFZb v. 10, 27, 1965). The results show that the resistance and relaxation-time inhomogeneities of the pbotocurrent greatly influence the form of the spectrum and the spectral distribution. The noise spectrum exhibits characteristic peaks which are due to the presence of a narrow high- resistance region near one of the electrodes, and such an inbomogene- ity leads to bigh values of (AN2)IN >> 1. There is no clear-cut ex- planation of these peaks as yet. The authors thank V.-Ye. Lgshk=e-Y, J.. for interest in the work and a discussion. Orig. art. has,: 5 figures., 4 formulas, and 1 table.

To measure Hall effect, speci- mens shaped as a parallelepiped (15 x 4 x 1 mm) were used; for other investigations, specimens 4 x 3 x 1 mm were used. The neutron irradia- tion was carried out in a VVR-11-type reactor at a temperature 'below 70C. Tho.gamma-ray.irradLation was ca'rried out in a cobalt installs- tion at a temperature below 20C. To determine the 'character of the Card 1/ 2 A ACC NR, AP6012459 defects appearing in CdS single crystals due to neutron and gamma-ray irradiation, the following crystal characteristics were investigated before and after irradiation: dark resistance, photosensitivity to white light, spectral distribution of photoconductivity, spectra of infrared quenching, Hall mobility of majority current carriers and Its dependence on temperature, concentration and depth of occurrence of capture levels, characteristics of recombination centers, and lumi- nescence spectra at 300 and 77K. Hobility and spectral distribution of photoconductivity were measured in a cryostat at a vacuum of the order of 10-4 mm Hg. All other characteristics were measured in Ithe, air. It was found that gamma-irradiation primarily creates acceptor- type defects. In CdS. the simplest acceptors can be Cd vacancies or S atoms in interstices. Neutron irradiation creates donor-type defects. The simplest donors can be either Cd atoms in interstices or S vacancies. In addition, the products of nuclear transformations can also be donors.

By measuring the frequencies corresponding to the two transitions and by measuring directly the fraction of the released holes as a function Of the temperature, it becomes possible to determine the ratio of the- the 1probabilities of the two processes and the excitation energy of lexcitation level. The results can be reconciled,w1th theoretical calculations only by assuming the presence of the two simultaneous Capture mechanisms. It is pointed out that this demonstrated possi- bility of simultaneously realizing two different carrier capture Mechanisms by the center should be taken Into account both during the interpretation of the recombination and luminescence processes on impurity centers in semiconductors, as well as in the study of the properties of different F and V centers in alkali balide crystals.

At low temperaturesp a strong dependence of ~L photoelectric proper- ties on the conditions of cooling and illumination of the samples was observed. This is shown to be due to the photochemical formation of new types of trapping centers (t-centers) and sensitizing recombination centers (r-centers), as in the case of Odso which was studied earlier. The main parameters of these centers were determined. The forbidden gap width, hole mobility, spectral and temperature characteristics of the photocurrent, temperature dependences of the dark current, ate. were measured. It is concluded that the formation of new types of r-centers in CdS and 1n4S5 provide information of the nature of "ordinary" r-centersp since their properties - small cross section of capture of majority carriers and large ratio of capture cross sec- tions of carriers of both signs - are similar. authors thank V* To.

Grade 600 concrete can be used where greater Gtrength is desired in conjunction with the use of lesser amounts of ,,eoncrete, such as in slotted columns with 12-meter spans for buildings with over- head cranes., 24-meter-span trusses for loads of 350 kg/m2 and higher (with 12- meter spans), 30-meter trusses with uniform loading, 3 x 12-meter slabs. Although grade 800 concrete can be used for various sections, such as 30-meter trusses, 3 x 12-meter slabs and 18-meter girders with some decrease in :.the volume of concrete, tests have shown that concretes of grade 700 and higher are not feasible for -Wido~'u�6 in prefabrication techniques becaiise of unsatisfacto technology and manufacturing procedures. For this reagon further research wit higher-grade concretes must be undertaken. (Yrig. art. has: 4 figures and 5 t SUB CODE: 11 / SUBM DATE: none . .

Fig. 3 shows the design of Card i/2 Thermal Treatment of Oil Wells 92-58-8-9/36 the electric heater installed under the pumping unit, and used for continuous heating of the bottom-hole. While In oilfields of the Stanislavneft' organization the bottom-hole heating increased the petroleum flow 1.5 - 3 times, in some wells of the Sakhalin oil- fields it speeded the petroleum flow up to 13 times. Moreover, in some cases wax deposits were melted not only in bottom-holes, but also in pressure pump tubes,and thereffect of heating lasted several months. On the basis of experiments it can be said that the use of a mobile 25-30 kwt heater suitable for 8".. 6"1 or 411 wells is desirableand that a temperature around.150* C must be maintained at the bottom-hole. An i:ndependent, durable and flexible cil gas resistant wire rope shoi;ld be employed to suspend the electric heater. There are 3 figures and 3 tables.

TITLE: Depth Heaters (Glubinnyye nagrevatellnyye ustroystva) PERIODICAL: Neftyanoye khozyaystvo, 1958,~Nr 8, pp. 46-53 (USSR) ABSTRACT: The article presents data on Soviet and American depth heaters for oil wells. Stepanchikov's burner (Ref. 11, operating on the principle of flame propagation, is of limited capacity and lacks direct temperature control. It is also inclined to produce soot and contaminate the well. The American model of gas burner for underground generation of heat, presented by Fig. 1, fades out and ignites easily at low depths [Ref. 2]. Another American model presented by Fig. 2 and tested in a depleted forma- tion has markedly increased the yield of the formation [Ref. 31. The Institut nefti AN SSSR (Petroleum Institute, Academy of Sciences, USSR) has designed a gas burner which is supposed to satisfy most of the requirements. This Card 1/4 Depth Heaters SOV/93-58-8-10/15 burner, shown in Fig. 3, operates on the kinetic principle of fuel burning and its special feature is that the air-gas mixture which is introduced to the combustion area is prepared In advance. A triple cable of the KTSh-2 type delivers the electric power to the Ignition and transmits the data recorded by the thermocouple which is located at the cutlet of the burner. This burner has been subjected to laboratory bench, and'industrial tests. The laboratory tests have shown that a burner 1,000-mm. long at 30 atm.and 3000 can have a heat capacity of 190,000 -' 380,000 kilocalories/hr. and a volumetric capacity of 2,000 ~ 4,000 normal cu. m.//hr. They have also determined that the change in heat capacity and volu- metric capacity is directly proportional to changes in the length of the burner or in the pressure. The bench tests have disclosed that combustion proceeds Card 2/4 Depth Heaters SOV/93-58-8-10/15 evenly without explosions and without drastic pressure rise in the system, and it is characterized by tem- perature jumps. During the tests the air was delivered by means of a UPK-80 compressor. The bench test results are shown in Table 1 and Fig. 4. The industrial tests have shown that it is expedient to employ this type of burner under fixed conditions at a time when the entire formation has been stimulated and heating substances injected in it. The temperature curve during the burner operation under industrial conditions is shown in Fig. 5. The Petroleum Institute 'Academy of Sciences USSR in cooperation with Giproneftemash has also designed a depth burner (Fig. 6) for preventing paraffin and tar deposition in the well. This unit was tested at the YablonoV3kiy oilfield of the Kinellneft' NPU and the results are shown in Tables 2 and 3. The tests have shown that this unit satisfies the industrial require- ments. The Institute has designed another burner Card 3/4 Depth Heaters SOV/93-58-8-10/15 (Fig. 7) for installation in the well under a deep well pump so that the bottom hole heating and ,oil production proceed simultaneously.

TITLE: Distortionlof the Modulation of High-p 19 During the Propagation%in the Ionosphere (Experimental Investigation). Part I. PERIODICAL: Izvestiya vysshilch uchebnykh zavedeniy, Radiofizika, 196o, Vol. 3, No. 3, pp. 367 - 374 TEXT- An investigation of the change of the modulation depth of an amplitude-modulated wave at the carrier frequency of 200 kc/s was carried out by J.W. King (Ref 6). It is considered, however, that the results obtained by J.W. King are not fully satisfactory V( since they cannot be used in studying the dependence of the amplitude distortion on distance. Consequently, a more detailed study of the problem was undertaken. The measurements of the modulation depth were carried out simultaneously at three different points by means of three specially prepared measurement sets. One of the sets was situated in the vicinity of the transmitter and measured the modulation depth produced by the transmitter; the second was situated at a distance of 2 000 Ian (point 4) while the third set could be situated at various distances from the transmitter Card 1/4 82447 s/i4l/60/003/03/002/oi4 E122~Eabjjo Distortion of the Modulation of High-po e a Waves During the Propagation in the Ionosphere (Experimental Investigation). Part 1. (points 1.2,3). Since the antenna system of the transmitter produced practically no vertical radiation component, it could be assumed that the receiver situated in the vicinity of the transmitter received only the surface wave whose modulation depth was the same as that of the transmitter. In order-to secure the measurement 0f the modulation changes with an error of 0-50% it is necessary to employ the measuring sets of very high stability. The measurement of the carrier level was performed by means of a linear voltmeter employing a copper oxide rectifier. The voltage obtained at the out- put of the rectifier circuit was applied to a 2-stage low-frequency amplifier, fitted with RC filters. These bandpass filters were tuned to frequencies of 40, 80, 160 and 600 cps, The output of the amplifier was fed to a peak voltmeter which was measuring the magnitude of the envelope of the �nvest�gated signal. The modulation depth was determined by comparing the readings of the linear and the peak voltmeters. The experimental investigation of the Card 2/4 82447 s/141/60/003/03/002/014 Ela2~EAffio Distortion of the Modulation of High-po e a Waves During the Propagation in the Ionosphere (Experimental Investigation). Part I. amplitude distortion due to the propagation of the waves in the ionosphere was conducted during the period from April 24, 1959 to June 18, 1959. A powerful radio station operating at the frequency of 236 kc/s was employed as the transmitter, the modulation frequencies being 80, 160 and 600 cps. The modulation depth was approximately 80%. During the above period 30 observations were effected at night-time,) the duration of each being 15 minutes (5 minutes for each audio frequency). All the 30 transmissions were received at the distance L = 2100 lun (point 4). Ten trans- missions were observed at the distances of 400, 700 and 1500 km from the receiver. The experimental results are given in Tables 1, 2, 3 and 4 and in Figures 1, 2 and 3. Tables 1, 2 and 3 shows the average relative values of the modulation changes. From the tables it is seen that while the modulation changes for any one observation did not exceed 2%. the differences between various observations are quite considerable. Table 4 shows the average relative values Card 3/4 82b47 s/141/60/003/03/002/014 EJR2~E~82 Distortion of the Modulation of Hig - o er Radio Waves During the Propagation in the Ionosphere (Experimental Investigation).

The dependence of the modulation distortion on frequency is illustrated in Fig. 1, while Fig. 2 shows its dependence on dis- tance. The nonlinear dependence of the magnitude of the distortion on the power of the transmitter is illustrated in Fig. 3. The authors express their gratitude to G.S. Kharitonov, S.I. Volosnikov, B.I.

It is presumed that both the telluric field and the field of radio stations in a remote zone are identical, in relatively small areas, to the field of a quasiplane vertically polarized wave, and the fundamental properties of the field in a stratified medium are discussed.

When observing tellurio currents, the problems of the structural and geological mapping of the orig.Lna-; rocks which occur under conducting deposits lying horizontally with a thickness up to hundreds of meters, can be solved successfully. It is pointed out, that the study of the phase relations in the telluric field may turn out to be of interest for the geological Interpretation of anomalies.
