I, Moscow, Fizmatgiz, 1958, pp.,63-109 TEXT: This is a description of the mathematical apparatus of programming for oomputers whose computing elements perform addition and substraction (additive machines). The matrix calculus is the mathematical basis of this apparatus. Many of the facts, established f6r additive machines by means of the matrix ap- paratus, can be applied to machines of any type. Command and program operators, input operators and program cycles (homogeneous and inhomogeneous ones) are con- sidered. A definition of the homogeneous computing problem is given and con- ditiDns of programability of its solution by a homogeneous program cycle are formulated. It is shown that the problem can be programmed on a given machine if functions obtained in the machine coincide with the sought for functions in a L/ JV Card 1/2 S/112/t5g/000/015/033/068 On Some General Problems of Programming A052/AO02 certain given beforehand set. An example of using the programability conditions for solving a homogeneous computing problem by an inhomogeneous program cycle is considered. Possibilities of widening the class of operators solvable by program cycles are analyzed. The author gives a method of calculating the input function which must be put into the machine and with which the solution of a problem starts. The problem of programability of the solution of an Inverse problem (negative powers of an operator) is considered. The possibility of solving an inverse problem without inverting the operator Is established, which is im- portant when a computing problem is given in an implicit form. Conditions are discussed under which a simultaneous solution of several different computing problems can be realized in a machine by means of one program cycle. There are 16 references. E.A.G.

In the paper are considered different methods of speedinf-up operations in digital computers. Methods of accelerating the digit by digit multiplication by overlapping in time the operations of ad,41tion and shift; the method of the "travelling wave" when the addition of several partial prodvets is affected simultaneously, etc. For speeding-uO thedivision operation a method is recommended by which the infor- mation contained in the c6de of the next remeinder is used for determininq in one step the group of the quotient consecutive digits. Are considered the adv,,,ntages, from the point of view of operation speeding-up, of storage of codes in not normalized condition and representntion of negr-tive numbers in the machine in reverse code (with Introduction of code feature).

Methods are described for 3peeding-up the addition elementpry operation, which ensuke single-shot operation of each component of the add circuit, as well as the methods of speeding up the group shift by means of a special shifter designed in the form of a f errite matrix.

In-ta gorn. dela AN UkSSR, 1956, Nr 4,(13), pp 100-107 ABSTRACT: The author describes the results of 87 experimental explosions in limestones kritical point of compression 600 kg/cn,2 to 1)400 kg/cm ), made by exploding charges 7 m to 22 m long in drill holes with diameters of 150 mm and 200 mm. The degree of crushing was determined by sieve analysis and was evaluated by the percentage of material remaining on the screen (Pn). The relation- Card 1/3 ship (W) between Pn and tne computed radius of 15-57-10-14877 The Influence of the Basic Technical Parameters (Cont.) fracturing (CRF) was determined. Experiments were conducted to determine the relationship between P and-the spacing of the charges. When the length of charges were 7 m ~o 22 m, for a constant value of (CRF), only the index measuring the spacing of the charges varied, and for these experiments this index amounted to 0.6 to 1.0 times the value of (CRF). The relationship between (CRF) and the length of charge was also shown by experimental explosions indicating that it is possible to determine the necessary value of (CRF) in respect to the diminution of length of charge so as to produce a minimum of coarse particles. An analysis of the results leads to the following conclusions. With an increase in the value of (CRF), there is a .considerable increase in the coarse fraction. The greatest crushing 1s obtained when the charge spacing is within the interval of 0.6 and 0,7. The size of the drill hole shows no relationship to the amount of rock crushing. 'The minim= size of'the hole which still. elimates ledges at the bottom of the charge depe-nds on the value of (CRF) and is about equal to 0.2 W. The optimum value of the coef- ficient of compaction (k) occurs within the limits of 0.8 (CRF) to 1.0 (CRF). To obtain the minimum coarse fraction it is necessary Card 2/3 15-57-10-14877 The Influence of the Basic Technical Parameters (Cont.) to choose a charge of such length, before lowering, that its extent in the bore hol'e be approximately equal to H - k-W.

(MIRA 16:n) "A Mechanical Method for the Production of-New Types of Polymers," by V. A. Kargin, B. M. Kovarskaya, L. I. Golubenkova, M. A. Akutin, and G. L. Slonimakiy, Rhimicheskaya Promyshlennost', No 2, Mar 57, PP 77-79 Equipment similar to rubber masticators has been designed for breaking down plastics by the exertion of mechanical force,, so that the fractional parts of chain molecules which are then formed and which possess the properties of free radicals may react with other chain molecules or parts of chain molecules, forming block polymers, or combine with monomers., forming grafted polymers. The equipment in question consists of two circular corrugated plates between which the material is triturated when the lower plate is rotated against the upper plate that remains stationary. Two different types of plates are described: one has a rectangular groove vith the contour of an Archimedes spiral and a depth gradient and the other a groove which possesses the same contour but exhibits a uniform depth and is cut in such a manner that a ridge with a profile corresponding to that of a- Whitworth screw winding results. The first type of. pUte vas found to be best suited for the copolymerization of low-molecular brittl e resins with elastomers and the second for combining different types of elastomers with each other. By applying the method of mechanical disintegration, block polymers representing combinations in different proportions of nitrile rubber with phenol-formaldehyde novolacs, epoxy-resins, and refined coal-tar pitch were obtained. The time required for the experimental preparation of the block polymers was 4-5 minutes.- Samples weighing 10-20 g were used., and the mechanical disintegra- tion was carried out in an atmosphere of inert gas. . The authors conclude on the basis of the results described by them that the mechanical method of producing block polymers and grafted polymers is superior to chemical methods. They add that an ,appar&tus for the continuous production of block polymers and grafted polymers by the mechanical method is being developed at the Scientific Research Institute of Plastics, and that the avail- ability of this apparatus will make possible the industrial produc- tion of such polymers by the method described. The authors of the article exp !--in the significance of the work on block polymers as follows: "At present requirements of a complex nature are put in various branches of the industry to products made of high-molecular compounds.- These requirements comprise superior heat stabilii;y, improved mechan- ical and dielectric characteristics, stability to the action of vatero chemical stability, retention of the original characteristics aft-r prolonged use of the products,, and stability at low temperatures com- bined with a resistance to the action of gasoline and oil. However, none of the available types of polymers can completely satisfy all the requiruments mentioned above. For that reason it has become necessary to combine different types of polymers in such a manner that the materials resulting frizz their interaction vill possess all ~the desired properties," (U) ld,IJTIII, 11.

TITLEt Thermomechanical Investigation of Epoxide Resins (Termomekha- nicheskoye issledovaniye epoksidnykh smol) FERIODICALt Kolloidnyy Zhurnal, 1958, Vol. xx, # 1, pp 34-37 (USSR) ABSTRAM Epoxide resins may be either thermoplastic or thermoreactive, depending on the initial diphenyl propane and epichlorohydrine components. Thermoreactivity begins at a molar ratio of I s 1.5 of the initial components and at a further decrease of the epichlorohydrine content. The thermomechanical curves of the initial resins were obtained on a dynamometric scale. The solidified specimens were measured on a consistometer. Epoxide resins are low-molecular, i.e. they pass from the vitrified condition into a viscous-fluid one. The vitrification tempera- ture varies between 5-50 0C. Solidified resins are prepared by using a hardening agent, polyethylenepolyamine, for 30-45 days. The reduction of the epichlorohydrine content to a ratio of 1 1 1.2 and a 10-hour heating at 2000C produces the resin type ED-15, which is elastic at increased temperatures. Card 1/2 Resins with 10WOT numbers of epoxide groups are more elastic Thermomechanical Investigation of Epoxide Resins 69-20-1-5/20 at increased temperatures than those with higher numbers. Thermoreactive resins, solidified without addition of a har- dening agent, have a higher heat resistance and have a better appearanos than those solidified by amines and resol resins.

TITLEs The Method of Heterogeneous Polycondensation PERIODICALt Plasticheskiye massy, 1960, No, 2, pp. 14-17 TEXT: The authors *studied the possibi.lity of obtaining polyamides on the interface, with and without mixing of the heterogeneous systems L. A. Sakharova, S. A. Gershkokhen, and L. P. Nekrasova participated in the ex- perimental work. Their results confirmed those obtained by V. V. Korshak and correspond to the reaction mechanism proposed by him, at which a re- action component present in abundance does not inhibit the reaction of the end groups with other initial substances, so that the polymer chain con- tinues to develop. If the polymer is formed on the interface as a film which pre-rents further development of the polymer chaint the interface must be continuously set free. This is done either by mixing the hetero- geneous system or by continuous polymer extraction at the interface, the latter process having been performed by means of the mechanical instal- lation by M. P. Shapenko, which also permits to vary the extraction rate Card 1/2 The Method of Heterogeneous Polycondensation B/191/60/000/002/003/012 13027/BO58 from 0-5 to 12 m/min. Individual factors influencing the yield and molecular weight of the polymers were also studied, e.g., the addition of certain salts (Ref. 8) to the aqueous phase and of surface-active sub- stances during mixing; an increase of the polymer yield up to 75-90% was thus obtained, It was also found that a certain feed rate of the reagents must correspond to a certain extraction rate. Polycondensation on the interface took place at 220C + 20; an increase above 20 to 250C is not suitable since the diffusion of the reagents increases. Polymers with different physical and chemical properties are manufactured by the above method, according to the initial componental i.e. diamine and diacid anhydride. Phthalamides an(l polyamides without hydrogen bonds are of interest, as well as the production of copolymers with given properties; furthermore, polymers may be obtained on the basis of products such as ethylene diamine, which at present is not used for the production of high-molecular polyamides according to the homogeneous method.

Glass Textolite on the Basis of Polyvinyl Butyral PERIODICAL: Plasticheskiye massy, 1960, No. 3, PP- 48 - 49 TEXT: -The authors report on their studies of methods of producing glass textolite from polyvinyl butyral (PVB) with glass fabric of the type ACTT (6) (ASTT (.b)),as-a filler. They used A-type PVB, and found that PVB embrittles at high temperatures, and loses its elasticity and solu- bility. Also its impac t strength decreases, whereas hardness and bend- ing strength increase., At high temp *eratures, PVB decomposes, becomes sticky, and its mechanical strength decreases. This was ascribed to a change in molecular structure, which changes from linear to steric with numerous cross links (Refs. 2,3). In glass textolite, the PVB content dropped to 4% after impregnating the glass fabric with an 18% PVB solu- tion after drying at high temperature. Glass textolite was produced for Card 1/2 87655 Laminated Plastics on the Basis of Glass Fiber. S/191/60/000/003/008/013 Report VII. Glass Textolite on the Basis of B016/BO54 Polyvinyl,Butyral experimental purposes a) by molding at different pressuresand b) by de- formation in vacuo. The authors studied the effect of temperature, PVB content, and deformation pressure on the properties of glass textolite. They found that a change in the PVB content has no great influence on the quality of glass textolite. A pressure of more than 45-50 kg/cm2or howevery effects a decrease in strength with the use of most kinds of resint probably due to destruction of the filler. It is shown that with the use of PVB a much higher pressure can be applied, without d.etri- mental consequences, than with the use of other resins. Further$ the authors found that PVB glass textolite deformed in vacuo has a lower strength than phenol glass textolite produced in vacuo. Experimental results.show that the increased specific pressure endured by PVB products improves their quality. The properties of PVB glass textolite can be changed by additional heat treatment.

TITLE: A Block Copo3ymer of Epoxy- and Dimethyl Resorcine Resins as Binding Agent-for Glass-reinforced Plastics PERIODICAL: Plastiche6kiye massy, 1960, No. 5, PP. 10 - 11 TEXT: This paper discusses a study of block copolymers obtained from epoxy resins of the A-5 (ED-5) and 39-6 (ED_ 6) types, and dimethyl resorcine resins. The epoxy resins were obtained from diphenylol propane and epichloro hydrine in alkaline medium, and contained 18 - 20 rit of epoxy groups. Dimethyl resorcine resin was obtained by condensation of dimethyl resorcine with formaldehyde in the presence of mono- or polyValent alcohols. A combination of 70 % epoxy resin and 30 % dimethyl resorcine showed the best properties: Brinell hardness 30 - 34 kg/mm2, heat resistance according to Vicat 115 - 1250C, compressive strength 1300 kg/cm2. Glass fabric was steeped with the unhardened copolymer, dried at 70 - 600C, and then pressed. The binding agent content was (~O�2)%.

I TITLE: Production of Block Polymeraland Grafted Polymers by Means of Spark Dischar e i a Liquid .PERIODICAL: Plasticheskiye massy, 1960~ No. 6, ppc 2 5 TEXT: The authors report on experiments made with an apparatus ache- matically shown in Fig. 1. Spark discharges were generated in a vessel (Fig. 2) filled with the substances to be polymerizedl a shaping spark gap was connected in series with the spark gap in the vessel. The con- denser potential attained 60 kv, the energy stored was about 100 joulest the discharge frequency was about 0.5 - 1.5 cps. The authors discuss the effects of the spark (hydraulic and cavitation surgeg formation and re- composition of,free radicals), as well as the influence of aperiodic discharges on the transformation of electric energy into mechanical energy.

After 5 hours of spark discharges at 20OCp the authors performed a heating to 1000C, a precipitation of the oyclohexane and the methyl methaerylate not having reacted by means of ethanol, and an extraction of the poly- methyl methacrylate and the polymer with a low content of polyvinyl chloridekk LP' by means of glacial acetic acid. The insoluble fraction contained Pkknd grafted polymer with a high content of vinyl chloride. A comparison with a solution not treated with sparks (Table) showed that in this case the injpoluble fraction contained only 37 molecules of methyl methaerylate'iper 100 molecules of vinyl chloride whereas in the Fle r7ra-cri-on of a spark-treated solution 100 molecules of vinyl chloride contained 63 molecules of methyl methacrylate. Thus, the yield in grafted polymer was doubled. Block polymers were produced from 5% solutions of PVC and ethyl cellulose (1 : 1) in equal parts of ethyl acetate + cyclohexane under the same conditions as the grafted polymers. The chlorine content of the insoluble fraction was 45%. There are 2 fig- ures~ 1 table, and 13 references: 9 Sovietv I British, 1 Belgian, and 2 German.

TITLE: Synthetic Thermosetting Resins on the Basis of Low-molecular Liquid Butadiene - Styrene Copolymers PERIODICAL; Plasticheskiye massy, 1960, No. 10, pp. 6-8 TEXT: The results of experiments conducted for obtaining low-moleoular butadiene-styrene copolymers are described. These copolymers were examined for their usability in the production of thermosetting rosins. Divinyl and styrene copolymers were produced by a method developed at the kafedra sinteza polimerov MITKhT im. Lomonosova (Chair of Polymer Synthesis of the Moscow Institute of Fine Chemical Technology imeni Lomonosov) (Ref. 10). [Abstracter's Note: The method is not described here). The initiators used were benzoyl peroxide, diphenyl ethane hydroperoxide, cumene hydwoperoxide. The yield obtained under optimum conditions was 60-65% referred to the monomers. The copolymer contained 20% styrene.

The low-molecular copolymers obtained were examined for their molecular weight, their double bond content, and their 1,4-bonds (by means of perbenzoic acid), and their hardening capacity was tested at 130-1801C. The copolymers obtained by means of sodium (molecular weight 4000-6000, 21-23% 1,4-bonds) are hardened within 8 hours to form a resin which is insoluble to 94%. The substances polymerized in emulsion molecular weight 3000-i-5000) and in solution (molecular weight 1500-3000) 50-52%, 1,4-bonds) remained elastic after 40 hours of hardening and ~ contained only 83-90% of insoluble substances. The glass reinforced plastics produced therefrom were resistant to humidity and had a breakdown voltage of 18.9-32 kv m; bending strength of 1080 kg/cm2 and a Brinell hardness of 8.9 kg/mm~m . Epoxidation by means of peracetic acid or perbenzoic -.aid yielded resins which contained 3-5.8% epoxide groups, hardened on heating within a few hours and were insoluble to 96-98%. S. S.

TITLEs Interfacial polycondensation PERIODICALs Plasticheskiye massy, np..I, 1961, 10 - 11 TEXTt A study has been made of the acceleration of condensation of epoxy resin with dephenylol propane (DPP) by interfacial polycondensation, "sing diphenylol propane (melting pointp 153-1560 C) and commercial 97% ~,qichlorohydrin (EPC). The DPPtEPC ratio was 10.25, 10.5, lt2.3, or 10. The end of the reaction was ascertained from the DPP content of the aqueous alkaline solution. The percentage of epoxy groups, Vo at 1&l.25, rose to 2C% at la8. Fig. 2 shows that the optimum concentrations of the sodium salts of DPP and EPC are obtained in the aqueous and organic phase, re- spectively. At this concentration, a resin with maximum content of epoxy groups is obtained. Besides$ the content of epoxy groups depended on the organia solvent used for the purpose. Solvents in which the forming reCJA was unsoluble, yielded resins with a lower content of epoxy groups.

The highest content of epoxy grouj)B was obtained from n-butanol at any ratio. Polycondensation could be shortened by thorough mixing and an inorea3e of temperature from 35 to 9000. Mixing, temperature increase, and condensation time had no effect on the content of epoxy groups. The reaction time of interfacial polyoon- densation was 15-50 min as compared to a time of 120-360 min required to perform polycondensation by fusion of the components.

L., Yemellyanova, TITLE: Polyamide epoxy resins.-as initial products for glass-reinforced plastics PERIODICAL, Plasticheskiye massyt no. 2, 1961, 17 - 22 TEXT: No data have been published as yet on the use of polyamide resins as binding agents for glass-reinforced plastics because of their poor ad- hesion to glass. Methylol polyamide resins are distinguished by very high adhesive power, but glass-reinforced plastics made with them are insuffi- oiently hard and of low resistance to water. On the basis of the good ad- hesion of epoxy resins, their stability against water, their hardness and brittleness, the authors considered it to be convenient to combine these resins with the high-elastic polyamide resins, and to examine vhether the resulting polymer can be used as a binding agent.

B118YB203 lol polyamide resins was unsuccessful since the mixture did not solidify on heating. Only by synthesizing the polyamides via the intermediate stem of methylol polyamides and reacting them with diphenylol propane and epi- ohlorohydrin it was possible to obtain a grafted polymer. On heating, the resulting redin passes over into an unmeltable and insoluble state. Con- densation and hardening of resins were studied in different variations; the reactions of diphenylol propane with formaldehyde, of epichlorohydrin with formaldehyde, and of diphenylol propane with methylol polyamide were investigated. The studies confirmed the assumption of the character of reaction of these resins. The analysis showed that the following scheme holds for methylol polyamides resulting from the reaction of formaldehyde with polyamides via the methylol groups with the epoxy groups of the epoxy resin and with the methylol groups of the diphenylol propane radical in the epoxy resin; Card 2/~ Polyamide epoxy resins ...
