Title: Improvements in or relating to rubber solutions and cements
IPC: C08K5/25
Filed: 1936-09-11
Abstract: The viscosity of solutions of rubber in aliphatic solvents is reduced by the addition of an alcohol and an asymmetrically substituted hydrazine or derivative thereof, or mixtures of these compounds.  The term alcohol includes polyhydric alcohols and alcohols having ketone, ether, carboxyl and amino groups. Specified hydrazine derivatives are phenyl hydrazine and its oxalate, o-tolyl-, a -naphthyl-, o-xenyl-, 2 : 5-dichloro phenyl-, m-nitrophenyl-, p-nitrophenyl-, and cyclo-pentamethylene hydrazines, asymmetrical diphenyl- and dilauryl hydrazines, the benzoyl derivative of phenyl hydrazine, the phenol and a -naphthol and o -phenyl dithio carbazinic acid salts of phenylhydrazine, phenyl hydrazine-CO2 addition product, o-tolyl hydrazine-SO2 addition product, p-tolyl hydrazine-zinc chloride salt and methyl propylketone phenyl hydrazone.  As solvents, the hydrocarbons from hexane to dodecane, hexylenes to dodecylenes, cyclohexane or straight-run or cracked petroleum or petroleum naphtha may be used.  The rubber may first be treated with the hydrazine and dissolved in a mixture of hydrocarbon and alcohol, or dissolved in hydrocarbon and the solution treated with the alcohol and hydrazine. Fillers may be added to the cement; carbon black and sulphur should be added after the viscosity has been reduced.  Warmth promotes the action of the thinners.  The cements may be used for adhesives, impregnating, dipping or spreading, binders for wood flour, cork, cotton linters, wood or asbestos, or for the preparation of rubber isomers or derivatives. British Specification 480,178 and U.S.A. Specifications 2,018,643, 2,018,644, and 2,018,645 are referred to.

Abstract: 506,978. Windscreen-cleaners. AUTO UNION AKT.-GES. Aug. 25, 1938, No. 25058. Convention date, Aug. 25, 1937. [Class 138 (i)] A windscreen-wiper mechanism comprises both mechanical and manual driving means, and clutch means such that either driving means; when brought into operation, is automatically clutched to the wiper actuating gearing without the other driving means being affected, and that the manual means may be operated concurrently with the mechanical means so as to supplement the latter. As shown, Figs. 1 and 2, a pinion 1 driven by an electric or fluid motor or from the vehicle engine is rotatable on a shaft 8 and is fast with the member 2 of a free-wheel device 2-4, of which the driven member 4 is also rotatable on the shaft 8 and is fast with the driven member 5 of a second free-wheel device 5-7. The driving member 7 of this device is pinned at 15 to the shaft 8, which carries a manual operating crank 14. A rack 10 which drives the wiper shaft 13 is loosely and eccentrically mounted on the shaft 8 so as to be reciprocated by the driven members 4, 5. If the pinion 1 is driven, the members 2 and 4 are' clutched together by the balls 3, so that the rack 10 is operated. The member 5, however, rolls freely over the balls 6. If, alternatively, the crank 14 is operated, the 'members 5 and 7 are clutched together, while the member 4 rolls on the balls 3. Since the direction of driving rotation of both free-wheel devices is the same, the pinion 1 and crank 14 may be operated concurrently. In a modification Fig. 6, the driving member of each clutch device is in the form of a ratchet 22 co-operating with a pawl 21 carried by the,driven member 20. In another modification, one clutch device is a free-wheel device as shown in Fig. 2, and the other a ratchet-and-pawl device as shown in Fig. 6.

Title: Preparation of polymers of ª‰-lactones
Inventor: POLLOCK JOHN MACLELLAND
IPC: C08G63/82
Filed: 1961-07-12
Abstract: Poly-(beta-lactones) are made by reacting a 1:2-epoxide with carbon monoxide at a super-atmospheric pressure below about 500 atm., at a temperature below about 150 DEG  C. and in the presence of a metal carbonyl as catalyst. Specified epoxides are ethylene-, propylene- and styrene-oxide.  Suitable carbonyls are those of iron, cobalt, nickel or chromium.  The yield may be increased by the presence of a metal halide (e.g. potassium iodide or mercuric chloride) or a quarternary ammonium halide. The tendency of the epoxides to polymerize may be diminished by adding a base (e.g. pyridine). Catalytic amounts of water, methanol or hydrogen which assist the formation of the carbonyl halide (a possible intermediate catalyst) may also be present.

Abstract: 381,690. Plug couplings. ARNOLD, C. L. and M. K. ELECTRIC, Ltd., Wakefield Street, Edmonton, London. Sept. 11, 1931, Nos. 25537/31 and 1031/32. [Class 38 (i).] Combined with switches.-A switch and wall connector has means operatively connected to the switch mechanism which, when the switch is moved to the "on" position, will be moved to engage and cut into the pin of a plug part and prevent withdrawal of the plug until the switch is moved to the " off " position. The switch and socket part are mounted on the plate 1, and a metal L- shaped member 7 is carried at the end of one arm by a pin 8 mounted on the rear of the plate. The switch lever 5 extends through a slot 10 in the member 7, which is normally held in a catch 15 by the spring 12 connected at 14 to one arm. The other arm is bent at right-angles at 17, then at right-angles parallel to the plate at 18, again towards the plate at 19, and then parallel to the plate at 20, the part 18 being cut away to accommodate the plug. When the triple pin plug is inserted in the sockets 1, 2, 3 the third pin 26 passes through the socket tube 4 and, engaging the projecting part 22 of the member 7, releases the catch 15 and the switch lever can then be moved to the " on " position and in so doing moves the knife-edge 24 into engagement with the surface of the pin, thus preventing withdrawal of the plug. In the modification shown in Fig. 6, the catch mechanism comprises an arm 27 pivoted at 28, extending through a slot 29 into the socket tube and having a projection 30 engaging a slot in the member 7. Insertion of the pin releases the projection 30 so that the switch lever can be moved to the. " on " position. In another modification (not shown), the arm is moved transversely to the direction of the pin and releases a projection from engagement with a cut-away portion of the member 7. Specification 249,006, [Class 38 (i), Electric couplings &c.], is referred to.

Abstract: 782,176 Means for imparting double twist to yarn. POLLARD, H. Sept. 5, 1955 [Sept. 3, 1954], No. 25579/54. Class 120 (2) In a machine for imparting a. double twist to yarns, of the type in which . the supply of yarn is carried in a holder at the upper end. of a vertical twisting spindle, the yarn package holder is prevented from movement by a pair of sliding catches or bolts mounted on the yarn. package holder each adapted to engage a corresponding fixed bracket or the like, the catches being controlled by a cam or eccentric carried by the vertical spindle, the contour of the cam or eccentric being such that one or the other of the catches or bolts is always in engagement with its corresponding bracket and a gap is always left for the upward passage of the yarn. As shown the invention is applied to a doubling frame having two sets of spindles A disposed on either side of a central driving cylinder B and driven therefrom by endless driving belt C. The twisting head for imparting the double twist is indicated at D and the yarn supply package holder at E. Yarn from the package E1 may pass either through a wetting trough H or over damping rollers H1 to a yarn take-up package G1 on a spindle g carried by an arm g1. Each spindle A has a central axial passage a down which the yarn y passes, .the latter then. passing through a radial passage to a hole d in a horizontal flyer disc D1. The supply package support E is supported by ball bearings at the upper end of the spindle A secured to a downwardly extending member c2, which surrounds the spindle A and carries at its. lower end a disc E3. Mounted on the underside of the disc E3 are two sliding catches F which are reciprocated under the action of a cam or eccentric A1 and springs a3 as the spindle rotates. Outside the disc E3, fixed stops or brackets f are arranged each having a horizontal hole f1 adapted to receive the end of the corresponding catch F so that as the spindle A rotates first one catch F and then the other is engaged in its respective hole in the brackets f. The contour of the cam A1 and the distance which each catch F enters its hole is such that one or other of the catches is always in engagement with the brackets f so that the supply package E is always held stationary and further the distance between the ends of the catches F and the brackets f is such that there is a free passage between them for the upward travel of the yarn when the catches are withdrawn. The disc E3 may be replaced by a pair of arms and each catch F may be connected to a sheath of eccentric form on the spindle A so as to give them a direct reciprocating movement. Embodiments are described in which the supply package is a single horizontally mounted cheese; a number of horizontally mounted packages or a vertically mounted cone type package.
