The rate of dis- solution was determined from the weight loss of the germanium plate dur ing the experiment. Up to about 0.3 N K3Fe(CN)6 the process is of the first order. The addition of alkali up to 0,7 N KOH increases the rate of the reaction, but with further increase of the concentration of al- kali the rate of the process decreases. Stirring affected only those alkaline solutions in which the rate of dissolution increased up to about 1800 rpm* The rate of dissolution was identical for both the p- and for the n- type germanium.

Stable generation or amplification of oscillations in the centimeter and millimeter wavelength ranges is produced by placing the semiconductor diodes in a resonance or waveguide system, connecting them in a DC circuit and selecting their parameters and working points on the voltage- current curve in such a way that the resistance of the diodes on direct current and on frequencies below the working frequencies is positive while the resistance in the working frequency range is negative and greater than the resistance of losses in the diodes and in the high-frequency circuit.

Viscosity decreased with increasing temper- ature and rheological properties changed in direction to Newtonian flow; the trans- formation occurred in plasticized melts at lower temperature than in pure polymer.

An Y_Vr7H (UZD-7N) ultrasonic flaw detector of TeMITMASh design was used. The investiga- t'ions wort conducted with h-f oscillatious.of 2.5 MG, with prismatic feelers prod- ucing a 300 sound beam angle, one feeler performing the functions of both trans- mitter and receiver. Silicon oil was used on the specimen surface, which ensured a dependable contact at temperatures about 1500C. Butt welds were prepared in 14 mm thick 35X3H3M (39".3M) medium-alloyed steel with straight edges and single- bead welds. The shape was chosen for conveniencefor cold cracks in such welds usually develope at about right angles to the surface, and the reflection is clear.

However, vertical internal cracks in metal do not produce such an effect, and it was not possible to watch and record slight in- .creases of cracks of this kind. It is emphasized that also other flaws than cracks (cold shuts, notches) are being reflected, and preparatory experiments are neces- sary with specimens of the chosen geometric shape to spot and determine the other reflections before the tests. The lengthof cracks is determined as usual in such flaw detection, i.e. by two positions of' the fee'ler being moved to and fro. The depth of cracks was judged by the changing amplitude of reflected signal. The amplification was correspondingly reduced, for otherwise the signals would reach beyond the screen. A graph was plotted by which the depth of cracks may be deter- mined with *0,5 mm accuracy. Error is bighest at about 1 mm Crack depth. At low -ions from notches were crack depths the accuracy increases to tO.2 mm. Reflect different from reflections from cracks. The data show that initial microscopic cracks are starting at both ends of the seam at the boundary with the base metal in 20 - 25 min after termination of welding, when the metal temperature is about 14o - 1300C, and the depth of initial cracks is below one millimeter. The number of initial cracks reached up to ten in 3 lirs. The crack propagation was different - some cracks remained stable for a long time *1d then propagated rapidly, and some vice versa.

A number of reports dealt with x-ray and gamma, ray flaw detection and new trends in this field. 0.M. Ignatlyev, and D.S. Gerchikov, Zh.V. Ostapenko, V.I. Mak-Mak, and V.M.

The Tcmakiy politekhnichaskiy institut (Tomsk Polytechnic Institute) has developed a new design for a small and light 25 mev betatron. Betatrons are intended for inspecting welds in high-pressure vessels (reports by A~A. Vorobtyevp V.I. Gorbunov, and G.N. Kok). The reports of M.N. Mikheyev, G.S. Tomilov and R.S.

Otdeleniye khimicheskikh nauk, 1959, Ur 8, pp 1421-1424 (USSR) ABSTRACT: The present paper discusses the synthesis and properties of some of the compounds mentioned in the title. The properties of the synthesized materials are given in table 1. Nearly all substances crystallize at low temperatures; only 2,4-di- methyldecane and 3,5-dimetbyldodecane.vitrify at much lower temperatures than do their isomers or adjacent homologs. Besides reference 3 investigations aiming at an explanation of these phenomena have also been carried out by Petrov (Ref 4)- It was assumed that the characteristic feature of vitrification of the two compounds mentioned is due to their structure. Various investigations were carriee out to prove this assumption (determination of viscosity as a function of temperature (Table 2) and determination of nolecular weight). From the results it is seen that the influence of Card 1/2 the structure on the vitrification effect cannot be limited.

Official opponents - Doctor of Teclunical Scipncos Professor I. L. Kaganov, and Candidate of Technical Sciences Docent V. G. Komar. So: Elektrichestvo, No 4, April 1947, pp 90-94 ( U-5577, 18 Fobniary 1954 A highly developed critique was given of the simple mathematical methods of calculatin,c; hard rectifiers and of the methods of tabulating solutions with the aid of load norms. The principal shortcomings of these methods lay in misinterpretin,-, the lawa existing, between!ho varicus par,%netors of the rectifier circuit and the operating conditions. Erronom,2 poaftlates which had been adopted in the normatives were shown. A recomendation was made of a~graphlc-analytic method of calculat'!ng selenium rectifiers for admissive and. non-admissive mritching in of these rectifiers. Using., the method recommended the problems were investigated of using selenium rect- ifiers in single-phase surply circuits with a load in the form of a pure counter- electromotive force, without taking into account the active and reactive resistances of the power source. As a result of the investigation the circuits were classified into four basic groups on the principal of similarity from the point of view of operation of the selenium rectifiers.
