PURPOSE: This book Is intended for design engineers, scientific workers and students. COVERAR: The book contains a description of an approximate method of stress analysis in critical sections of complex components. The method is based Card 1/6 Determination of Stresses in Critical Sections (cont.) 8oo on the nonplane (angular, cylindrical, spherical) section hypothesis. Analytical for=las are given for'the determination of stress concentra- tion factors for flat, rectangular, and circular bars of variable crosB secti"on subjected to tension, flexure and torsion. Results are presented of an experimental study of stress distribution in samples of variable sections having different dimension ratios. Illustrative examples of the analysis of beading and tension of a flat plate having symmetrical and asymmetrical cutouts and shoulders are given and examples'of tension, torsion, and bending of a shaft with cutouts and shoulders are also presented. There are 29 references, of which 24 are Soviet, 3 are English and 2 are German. TABIR OF COMM.

TITLE: The Ultrasonic Defectoscopy of Tire Casings PERIODICAL: Kauchuk i Rezina, 1960., No. 7, PP. 12 20 TEM In most Soviet plants the quality check of tire casings has been conducted until recently by external examinations and knocking. This method was satisfactory due to its subjective nature. The ultrasonic defectoscopy method is recommended. Figure 1 represents the operation principle of an ultrasound ap- paratus. The NIIShP of the Soviet Union has designed an apparatus which is de- scribed in great detail. It has 6 channels plus an extra receiver and.genrerator to ensure continuous operation 0 cases of a channel break-down. Figure 2 is an external view of the apparatus-P The circuit diagram (Fig. 3) of the apparatus contains a block of feeders, a generator, receivers and transmitters. The feed- ing block has its own regulators, located on the front panel of the casing. M. The circuit diagram of the feeding block is shown in Figure 4, and that of the gener- ator in Figure 5. The circuit diagram of the receiver Is given in, Figure 6. A diagrammatic cross-section of the transmitter is seen in Figure 7. The emitter Card 1/3 S/138/60/000/007/005/010 The Ultrasonic Defectoscopy of Tire Casings A051/AO29 contained in the metal body is made of barium titanate. The thickness of the bar- ium titanate plate is caloulated,from the formula 2200 2200 t 44, 50 so.that it can function at a frequency of 50 and 150 Mc. In the formula t is the thickness of the plate in mm, tP - the resonance frequency in Mc. The casings be- ing tested must be clean. Otherwise the defectoscope may give false readings. Water-is used as wetting liquid with additions of 10 - 15% ethyl alcohol to ensure more uniform wetting of the casing. The authors tested casings of various sizes, starting at 5.60 - 15 to 12-00 - 20. The number of correct readings represented 93% of the total tested. There were different defects present, such as imination, porosity, airbubbles, foreign bodies, destruction of the casing. The results of the tests conducted with the defectoscope are listed in Table 3. As a result of the experiments and tests carried out by the authors, several conclusions were drawn: 1) The defectoscope operating with 50 kc can detect defects in casings of small dimensions compridnga thin-walled body (5-60 - 15), as well as in massive casings with thick-walled bodies (12-00 - 20). 2) The size of the smallest de- feats detected with the apparatus on an equivalent surface was 7 - 8 mm in diame- ter, which shows that the apparatus has a high sensitivity. False data in most Card 2/3 S/138/60/000/007/005/010 The Ultrasonic Defectoscopy of Tire Casings A051/AO29 cases meant the detection of "false" defects. 4) The reliability of the apparatus in operation is high. DurIng-its functioning period (one year) no damages in the electrical part of the apparatus were observed. 5) The apparatus described can be installed in tire plants as a laboratory and production apparatus for selec- tive, total or combined flaw detection, as well as in automobile and tire-repair plants. 6) The drawback of the defectoscope is the absence of a recorder of the defects shown. The duration of the testing of one casing will be 4 min when an automatic recorder and a perfected tub are introduced into the design of the de- fectoscope. There are 3 tables, 4 circuit diagrams, 2 diagrams, 1 graph, I pho- tograph and 3 English references.

The tire cover is submerged into the liquid, the ultrasound emitter is introduced Jato the cover and the receivers of.the ultrasonic vibrations are placed tround the part of the cover to be tested..The emitter applied may operaia at frequenoies of 90 and 156 ko/sec. The vibrator of the emitter is a ring-shaped barium titanate piezo element which is placed in a cylindrical plexiglass casing. An oil film between piezo element and casing is used as acoustic contact. The electrodes are applied to the inner and outer surface by means of Card 1/2 Ultrasonic Quality-Control of Tires S/032/6o/o26/O11/P15/O35 BO15/B066 silver paste. The vibrator of the receiver consists of a rectifier, a piezoelectric crystal plates and:a reflector. The m,chanioal part of the testing instrument consists of a container for the -'iquid and auxiliary mechanisms. Tires of any dimension can be tested. By means of the mechanism the tire can be rotated with a speed of 2 rpm. Tests with pure water, 15% alcohol in waterg 0.5% solution of "nikal" in water and 0-5% solution of the 0f1-10 (OP-10).wetting agent. 'In water disclosed that wetting with water and with thealcoholic solution is irsufficient..' that, however,the wetting agent solutions considerably foam, so that a suitable contact liquid had to be selected.

TITLE; Thermal and Tensimetrical Investigation of the System NbC1 _FeC1 NaCl 5 3 PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy. Khimiya i khimicheskaya tekhnologiya, 1959, Vol 2, Nr 4, PP 485 - 4aq (usn) ABSTRACT: The investigation of the subject mentioned in the title is of interest with regard to the preparation of easily fusible melts containing niobium as well as to the purification of KbCl from FeCl 3. The system mentioned in the title is part of the q ater- nary system NbC1 5_FeC1 3-AlC1 3-NaCl. A thorough investigation of the latter will make it possible to produce melts with a crystallization temperature lower than that of the adjacent ter- nary systems (Ref 2). In the treatment of raw material c.ontaining niobium by chlorine a simpler condensation device is sufficient for easily fusible melts. The binary lateral systems adjacent to the system mentioned in the title have already been investigated earlier (Refs 3-5). In order to investigate the ternary system, Card 1/3 five inner sections were made, and several mixtures determined Thermal and Tensimetrical.

The authors investigated the interaction of thorium chloride with chlorides of sodium, potassium, cesium and cerium in melts, for the purpose of- completing the knowledge about-the physical and chemical nature of a6mbe techno- logical processes of thorium chloride preparation. Thorium chloride was prepared by oblorination of thorium dioxide mixed with charcoa from sugar,, by gaseous chdorine at 1,000-1,0500C. The melting temperature of the chloride obtained was 7500C. Vapor tension of thorium chloride corresponding to its melting tempera- ture was about 80 mm Hg. Cerium chloride was prepared by the method described in Rereren,3e 16. The melting temperatures of chlorides of addlien, potassium, cesium and cerium were 800, 776, 646 and 802'c, respectively.

The authors of the present .Card I/rb s/149/61/0oo/oo1/0o3/013 Study of Fusibility of the NiCl _TiCl2-NaCl System A006/AOOI article studied fusibility of the TiC13-NaCl system and of the TiC13-TIC12-NaCl system within the concentration range of lower titanium chlorides determined by the electrolyte composition for Ti refining. Trichloride of Ti was obtained by reducing tetrachloride of Ti with Ti metal by a method described in Ref. 10. Sodium chloride was preliminarily remelted. Investigations of fusibility were carried out by the method of thermal analysis; the curves were registered on a N.S. Kurnakov type pyrometer.. The temperature was measured with a platinum-plati- num rhodium thermocouple. Melting of the salt system was performed in Stepanov's quartz glass and in stainless steel containers. The salt mixtures were prepared by a method described in Reference 7. Cooling curves were obtained for molten mix- tures containing up to 49.8 mol % (72.4 weight %) TiCl 3` Results of thermal ana- lysis, given in a diagramP are in agreement with data of Reference 8 and differ considerably from data of Reference 7 at a TiCl concentration of over 25 mol.%. This is explained by the Imperfect investigatiog method employed by Markov and Chernov, who melted the mixtures in open crucibles. According to data obtained by the present investigation, the components of the system form an incongruently melt- ing NajTiC14 chemical compound; the temperature of peritectic transformation is 5430C.. ~ Eut'40tics, formed by the chemical compound and titanium trichloride, has a composition of 43 mol% TiCl 3 and,57% NaCl, and melts at 4600C.

This shows that the system Is not a strictly binary one. Fusibility of the ternary TiC13- TiC12-NaCl system was studied within a small range of lower titanium chloride con- centrations. Previous studies had shown that in alkali metal melts, containing lower T1, chlorides, an equilibrium between bi- and trivalent titanium was estab- lished.

Eleatroconduativity of the system was studied on melts contain-';+'" ing up to 9.2% titanium chlorides, in the 820 - 9500C range. The method and equip.,,"'_~ ment, described in Reference 6, were used. It was found that the eleotroconduc- .0. tivity of the system decreased at the given temperatures at aoooncentration of titanium chlorides raised from 0 to 9.2%,and increased with higher temperatures. J'The results must however be considered as approximate, since it was stat6d,l that the platinum electrodes employed for the experiments were partially.-dissolved in the electrolyte. 72 Card+ 3/5 VOLYNSKIY, Aleksandr Yakovlevich; BAZILEVY N.P.; nauchn. red.; SIROTINAP S,L.p reds; 1010~ V.I., red.

TITLE: The Equilibrium of an Elastic Cylinder of Finite Length (Ravnovesiye uprugogo tsilindra k6nechnoy dliny) PERIODICAL: V sb.: Issledovaniya po teorii sooruzheniy. Nr 7, Moscow, Gos- stroyizdat, 1957, pp 413-436 ABSTRACT: The paper discusses the problem of the elastic equilibrium of a hollow cylinder of finite length. Following the method of M.M. Filo- nenko-Borodich (Prikl. matern. i mekhan., 1951, Vol 15, Nr 2), the author constructs a stress tensor consisting of three tensors, namely, the fundamental, the supplementary, and the corrective tensors. The components of the fundamental tensor must satisfy the equilibrium equations in the absence of body forces and the given end conditions on the surface of the cylinder; several specific instances of surface loads are discussed: 1) Normal face stresses, 2) tangential face stresses, and 3) inner and outer pressure. The supplementary stress tensor is a special solution of the equation of equilibrium which Card I /Z leaves the cylinder surface free from stresses; a supplementary SOV/124-58-3-3133 The Equilibrium of an Elastic Cylinder of Finite Length tensor is constructed for the centrifugal force and for the gravity force. The corrective ten5or satisfies the uniform equations of equilibrium and the uni- form end conditions of the cylindrical surface and contains a number of arbi- trary constants which are determined from the condition of minimum poten- tial energy (the suggested solution does not satisfy Castigliano's theorem of compatibility). The author suggests that the corrective tensor be constructed in the form of atriple series'of the products of cosine-binomes and plain trigonometrical functions of the variables r, 0, and z V. K.
