The study was made with the help of radioisotope tracer technique using carbon monoxide labelled with C14 carbon (9000 pulse/min per me). In the tests, a mixture of Cl4kO + H2 (in the 1:1 by volume ratio) was passed over freshly prepared iron catalyst heated to 295 OC, the reaction was allowed to proceed for various periods and the products were then separated. The radioactivity of the separated hydrocarbons was then plotted against the reaction time and the number of carbon atoms in the synthetiBed hydrocarbons. The results obtalned indicated that both the condensation and polymerisation mechanisms are involved in the synthesis of the products. The actual mechanism prevailing at any stage of the reaction was found to depend on the experimental conditions. A general scheme was formulated for the various reactions that can occur when a stream of carbon monoxide/hydrogen mixture is passed over iron catalyst heated to about 300 OCS Card 2/4 I M9, 33496 On the mechanism of chain growth ...

The samples were annealed at 850C for 2 hrs and were stretched in the 1144-P testing machine at room temperature and at the deformation velocity of 2%/minute. The electrical resistivity of the samples was measured for the first time after this treatment, and then was measured again after the samples were annealed at 4500 for 4 hours. The metal structure was studiedwith the H3X-8 'microscope and with the Tesla BS-242 electron microscope. The results showed that 1/2 AccEssioN NR: AP4ol983.2 the deformation of Armco iron led to the accumulation og crystalline lattice defects and to the formation of subnicrocracks 400-900 A long, The process of cracking started at the residual elongation of 7-9% under the force of 32-33 kg/mm!2. The accumulation of dislocations,, and the development of cracks produced a vatiation in specific electrical resistivity and in the length of the curved section corresponding to the plastic region of the metal. At certain critical values of the residual elongation and of the stress applied, the metal plasticity I was lowered due to the appearance of submicrocenters of metal failure. These critical values have to be accounted for during the selection of mechanical and thermomechanical methods of working the material, Orig, art., hass 2 figures.

This led to their hypothesis that the appearance of the first contin- uity of the breakdowns of the material in the form of submicroscopic cracks became established in advance of the final breakdown. The results were presented in a ,table. It was fo'und that during static tension of technically-pure aluminum, copper, nickel,.and iron, the first submicroscopic cracks arose long before the final dis- Xuptio":n of-the samples with residual expansions equal to 0.15-0.30 from the expan- ision value attained at the moment of breaking down* The critical values were estab-; Card _1/2 ACCESSION NR: AP4029833 lished for the applied tensile stress and the elongation in which the first sub- microcracks arose in slip bands at the places of dislocation build-up near obstacles. The experimental by determined values of the tensile stress and the length of the submicroscopic cracks agreed with the theoretically calculated values. During defor- mation in the supercritical region, the recrystallization annealing of the deformed - samples did not lead to a completeireturn of the density of aluminum,copper, nickel,, and Armco iron.

TITIE: Increasing the light resistance-of plasticized polyvinyl chloride resins SOURCE: Plasticheskiye massy, no. 9, 1965, 64-65 TOPIC TAGS: polyvinyl-chloride, light aging, stabilizer additive, resin I ABSIRACT: Several organic compounds containing keto and hydroxy groups wem studied as stabilizers for plasticized polyvinyl chloride resins. Film samples of the latter were tested fortensile strength and elongation as a function of the amount an* nature of the light stabilizers added. Whle the tensile strength was not appreciably affected by the additives, the elongation was, indicating that structural changes took place in the polymers. Based on the change in elongation, one can select the most effective light stabilizer and establish its optimum amount which insures a constant elongation. As a result of the teetsti.- the light stabilizers can bearranged in the following order of decreasing stabilizing effectiveness: 2-hydroxy-4-methoxybenzophenone; tetrahydroxysebaco- phenone; 2,4-dihydroxysebaeophenone; diphenylolpropane; 2,47dihydroxyacetophenone;! ethyll orcinol; dihydroxyphenylcyclohexAne, "All the compounds tested were I-Card ------- --- - L 2677-66 ACCESSION NR-.

TITLE: A Comparison of the Production and Quality of Tube Ingots Cast in Open and Closed Moulds q3 PERIODICAL: Kohaoszati lapok, 196o,/,No.lO, pp-456-459 TEXT: The production of tube ingots of 332.5 mm diameter and 1400 mm length in A35-29CsB quality rimmed steel presents many difficulties. The introduction of closed-end moulds led to improvements in quality and recovery and the purpose of the present study is to compare advantages and disadvantages of closed versus open end moulds. The first criterion of a good tube ingot is the formation of a minimum 15 min thick sound skin. The depth of the skin is - in otherwise identical steel cast into a given mould - a fraction of the pressure acting at the zone of solidifi cation. The pressure is the sum of atmospheric and ferrostatic pressures and, in the case of closed moulds, ii is increased by the pressure of CO that is liberated in the zone of blowhole formation during solidification and partially trapped under the lid. This reduces the thickness of skin especially near the top Card 1/3 Y, A Comparison of the Production H/014/60/000/010/004/004 E190/E580 if the gap between lid and mould is partially blocked by frozen steel. For this reason, the 0 concentration of the melt should be increased; from experience it was found that the slag of open- hearth charges should contain 15% FeO against the 13% maintained when making steels for open-ended moulds. Sulphur segregation reaches 300-400% under the head of ingots cast in open moulds and may cause internal cracks in the rolling of steels with 0.05% S (i.e. thepermissible maximum). By restricting the time of solidification U.e. from the end teeming to the end of rimming) to 1.5-2 min in closed moulds, sulphur segregation can be limited to 120%. The distribution and composition of non-metallic inclusions is discussed with reference to H. Hoff, H. Lessing and G. Masing. Experience showed that the surface of ingots cast in closed moulds is more likely to show defects and inclusions which lead to fine surface-cracks in the piercing process. This, and the larger number of inclusions, the iron loss in slags of higher FeO content and higher mould maintenance costs are more than offset by the 25% increase in recovery of tube. Further improve- ments were obtained by after-desoxydation with aluminium powder. Card 2/3 A Comparison of the Production H/ol4/6o/ooo/oio/oo4/oo4 E190/11380 Too small (less than 0.15-0-18 kg/ton) aluminium addition Increases the viscosity of the steel and results in an ingot with heavy segregations, too high (more than 0.24-0.30 kg/ton) addition desoxydizes instantly, the steel behaves like killed steel and a deep pipe is formed. By adding the optimum 0.18-0.24 kg Al/ton steel, the depth of pipe is negligible, sulphur segregation is less than 70% and, since open ended moulds are used, surface quality Improves. The method has been used in this form for casting sheet material and recovery increased from 67.6% to 77.5%. At present, 0.1 kg Al/ton steel is used in tube ingot production primarily as a control over time of solidification in closed-end moulds and, as a result, recovery improved.

PURPOSE AND COVERAGE: The book has been prepared for engineers specializing in power units for cutters; it will also prove useful to students in higher education- al institutions. Problems are presented in the design and testing of power plants for cutters. The types of power plants now used in high-speed cutters are high- speed diesels, carburetor engines, and gas turbines. A brief description of the basic designs of cutter engines, reversing and reducing gear, and flexible couplIngs is given. Design considerations of the shafting, with specifies on high-speed and water-jet-propelled cutters, are presented. Other problems dis-- cussed include: depreciation of machinery on plastic cutters; noise and vibration damping; maintenance of individual mechanical units such as lubricating, cooling, and heating systems; remotecontrol systems; and the synchronization of separate support systems. The author expresses appreciation to A. A. Rikhter, 0. S. Rozhanskiy, and A. M. Radov for their review and comments. There are 24 references, 20 of which are Soviet. uDc: 629.124.82-8 TAKE OF COMMM (Abridged): Preface - 3 Introduction - 5* Explanatibn of symbols - 6 Ch. 1. Layout and.selection of mechanisms 8 Ch.

It is assumed that the oscillator is designed on the basis of an extended two-transformer oscillator cirenjit. The equivalent circuit and input equations describing the operation of such i an osciiLazz6r. are developed. The magnetization curve of the switching transformer core in the oscillator is approximated by a linearly broken curve, and the input characteristics by a set of parallel straight lines, which is accurate enough for the majority of power transistors. It is shown that the dependence of frequency on load is minimal when the following relationship is satisfied Card'l'/2 UDC: 621.373.42:538.56 ACC NR AR6035209 n,j, Vi interconnecting the load current Im, the power supply voltage E, the collector resistance rk, and the characteristics of the core material (through coefficient f, which characterizes the inclination of the hysteresis-loop branches of the switching transformer). One of the methods of satisfying this equality is to connect an additional resistance into the collector circuit. In oscillators whose oscillation period increases with an increase in load, the frequency stability can be improved by increasing the primary-winding resistance. Experimental results are given showing that with variation in load current from zero to the rated current it is possible to produce power -oscillators with a frequency stability of not less than 1-2016.
