Abstract: 409,882. Kinematograph apparatus. PAILLARD ET CIE SOC. ANON., E., St. Croix, Vaud, Switzerland. March 24, 1933, No. 8935. Convention date, April 16, 1932. [Class 97 (i).] Guides for use in forming the film loops during threading are hinged about the axes of the sprocket shafts, and guides within the loops are dispensed with ; the movable part of the gate may be mounted on a member which is moved to turn the guides, and the pivot of a feed claw may also be carried by this member so that the claw is free from the film track during threading. As shown, film guides 4, 10 are carried by arms 4<a>, 10<a> turning about the axes of sprockets 2, 11, and are moved by teeth which engage racks 14, 15 on a member 7 movable horizontally by rotation of a lever 13. The member 7 carries the spring-pressed aperture plate 6 of the gate, and also a pivot 19 upon which the carrier 16 for a claw 17 is reciprocated by a cam 18. The parts are in the position shown during threading, and, after threading, rotation of the lever 13 through 180‹ raises the guides 4, 10, closes the gate, and moves the pivot 19 so that the claw 17 engages the film. The fixed aperture plate 5 of the gate has a depression 22 into which the film may be pressed by the claw if the claw does not enter a perforation when the gate is first closed, and film guides 3, 12, movable from the sprockets by means of finger buttons 20, 21, may also be provided.

Abstract: 940,713. Plasticized synthetic polymers. FARBENFABRIKEN BAYER A.G. March 8, 1962 [March 11, 1961], No. 8966/62. Headings C3P and C3R. Plasticized elastic synthetic materials are prepared by admixing (A) a copolymer of ethylene and vinyl acetate and/or vinyl propionate, said copolymer containing 10 to 70% by weight of vinyl acetate and/or vinyl propionate, with 5 to 50% by weight of the mixture of (B) a polyether containing at least 10 units and having a molecular weight of at least 500. The polyether may be polyethylene oxide, polypropylene oxide, polytetrahydrofuran or reaction products of alkylene oxides such as ethylene oxide or propylene oxide with phenols, alcohols, carboxylic acids or amines, or of polyalkylene oxides with carboxylic acids and anhydrides, organic isocyanates and ketones, many of such reactants being listed. The compositions may be formed by direct mixing, or by mixing solutions of the components, e.g. in benzene, toluene, xylene, chlorinated benzenes, dichloroethylene or trichloroethylene; and may contain fillers, e.g. silicic acid and carbon black, dyestuffs and antioxidants. The compositions may be cross-linked by high energy radiation or vulcanised with the aid of conventional free radical forming catalysts such as peroxides and azo compounds. Vulcanisation is preferably effected in the presence of a cross-linking agent which is a compound of molecular weight below 1,000 which contains at least two non-conjugated carbon to carbon double bonds, and/or sulphur or a compound which splits of sulphur under the conditions of vulcanisation. Examples describe the preparation of compositions comprising (4) ethylene-vinyl acetate copolymer and polypropylene oxide; (5b) ethylene-vinyl propionate copolymer and polytetrahydrofuran dissolved in benzene; and of vulcanisates from (1) ethylenevinyl acetate copolymer, polypropylene oxide, stearic acid, silicic acid, dicumyl peroxide and triallyl cyanurate; (2) ethylene-vinyl acetate copolymer, polypropylene oxide, stearic acid, carbon black, sulphur, t-butyl cumyl peroxide and triallyl phosphate; and (3) ethylene-vinyl propionate copolymer, polypropylene oxide, stearic acid, silicic acid, 2,5-bis (t-butylperoxy)-2,5-dimethyl hexane and triallyl cyanurate. The compositions may be used for coating paper, glass, metals and textiles, or for making foils and shaped articles. In Example 5(a) a composition comprising an ethylene-vinyl acetate copolymer and polyvinyl isobutyl ether dissolved in toluene is described. Specification 843,974 is referred to.

Title: Improvements in and relating to the manufacture of isovaleric acid
Inventor: BING HEINZ
IPC: C07C51/29
Filed: 1948-03-31
Abstract: Isovaleric acid is obtained by oxidizing methyl isobutyl ketone with an alkali metal hypobromite or hypochlorite, preferably the latter, with subsequent acidification of the aqueous portion of the reaction mixture.  Bromoform or chloroform are also obtained. The hypohalite may be prepared in situ from the necessary halogen and aqueous alkali.  The reaction takes place essentially as represented in the following equation in which X=Br or Cl. (CH3)2CH.CH2.CO.CH3+3NaOX= (CH3)2CH-CH2.COONa+CHX3+2NaOH.  In examples: (1) commercial sodium hypochlorite (s.g. 1.25; 14-15 per cent available chlorine) is slowly added to methyl isobutyl ketone at 7-10 DEG  C., stirred for five hours at this temperature and for two at room temperature when after standing overnight the lower layer containing chloroform and unchanged ketone is separated and the aqueous layer after concentration and acidification with dilute sulphuric acid deposits the required acid which is collected and purified by distillation; (2) the above reaction is effected first at 45 DEG  C., then after addition of excess sodium hypochlorite at about 60 DEG  C., the reaction mixture being treated as before except that excess hypochlorite is removed by addition of sodium bisulphite to the aqueous layer; (3) methyl isobutyl ketone is suspended in aqueous caustic soda solution at 0 DEG  C., chlorine passed until the requisite quantity has been absorbed at 0-3 DEG  C. the reaction mixture then stirred for two hours and allowed to reach room temperature when after standing overnight it is treated p  as before except that the aqueous layer is heated in the water bath to remove chloroform and excess ketone and acidified without concentration; (4) is conducted in a similar manner to (1), sodium hypobromite being used at 10 DEG  C.; and (5) is similar to (3) using bromine in place of chlorine at - 1 DEG  C. to \sR1 DEG  C.
