Title: Improvements in and relating to the stabilisation of polymeric materials
Inventor: LAMBERT ARTHUR
IPC: C08L21/00
Filed: 1955-03-04
Abstract: The resistance to oxidative degradation of polyethylene and the non-rubbery copolymers of styrene or methyl methacrylate with butadiene-1,3 is improved by incorporating a 2-a -alkylcyclo alkyl-4,6-dimethyl phenol in which the alkyl group has not more than 4 carbon atoms, and the cycloalkyl is cyclopentyl or methylcyclopentyl, cyclohexyl or methyl cyclohexyl.  From 0.0001 per cent to 10 per cent by weight may be used and the compositions may be shaped as articles and films.  Copolymers of 75 to 95 per cent styrene and 25 to 5 per cent butadiene-1,3 and of 50 to 72 per cent methyl methacrylate and 50 to 28 per cent butadiene-1,3 are referred to.  The antioxidants may be incorporated on heated rolls, by mixing or by adding an aqueous dispersion or a solution, e.g. in ethylene glycol to a copolymer latex.  In examples: (1) polyethylene is heat softened at 140 DEG  C. on rollers, the 2-a -methylcyclohexyl-4,6-dimethyl phenol added and the milling continued.  (2) A latex of butadiene-1 : 3-methyl methacrylate copolymer is prepared by aqueous emulsion polymerization in an autoclave in two stages with sodium lauryl sulphate and potassium persulphate, chloride and hydroxide present in the first stage and sodium lauryl sulphate and the disodium salt of methylene dinaphthalene sulphonic acid in the second stage.  A solution of 2 - a  - methylcyclohexyl - 4,6 - dimethylphenol in ethylene glycol is added at a temperature of 50 DEG  C., and films are cast from the latex.  (3) A latex of butadiene-styrene copolymer was prepared under pressure in an autoclave using sodium lauryl sulphate and n-dodecyl mercaptan, and a dispersion of 2-a -methylcyclohexyl-4,6-dimethylphenol in a 5 per cent aqueous solution of sodium lauryl sulphate added.  The latex is coagulated with aluminium sulphate and a composition of the stabilized copolymer, pale crepe rubber, coumarone resin, zinc oxide, stearic acid, dibenzthiazyl and tetramethylthiuram disulphides, paraffin wax and sulphur is prepared on rollers at 50 DEG  C.

Title: Improvements in or relating to carbon brushes for electrical machines
IPC: C04B41/83
Filed: 1964-02-17
Abstract: 991,692. Impregnating permeable materials to form bearing surfaces. SOC. LE CARBONELORRAINE. Feb. 17, 1964 [Feb. 18, 1963], No. 6487/64. Heading F2A. In a method of manufacturing carbon brushes for electrical machinery wherein individual brushes or blanks therefor are impregnated with a thermosetting resin comprising a copolymerizable mixture of non-saturated polyester resin and an arylvinylic monomer, the impregnation being effected in the presence of a small quantity of a setting catalyst, and the mixture being then set by heating, a small quantity of a plasticizer compatible with the polymer is added to the impregnating mixture. The method may be applied to the partial impregnation of a brush or blank for effecting a uniform distribution of the resin in the carbonized materials, a mixture of a polyester, a monomer and a plasticizen being suspended in a suitable solvent, the evaporation of which does not tend to take with it the copolymers or the agents necessary for the copolymerization, and is self-containing the polymerization catalyst. In an embodiment, an impregnating mixture is made of the following norsodyne 66 (polyester of phthalic and maleic acids and polyethyleneglycol) 62% styrene monomer 3À5%, didecyl phthalate 2%, methylethylketone 30%, benzoyl peroxide at 50% in styrene 2.5%. The different components of the impregnating mixture correspond to the polyester resin, the arylvinylic monomer, the plasticizer, the solvent and the catalyst respectively. The catalyst is suspended in the styrene. The brushes or blanks are dried in air to evaporate the solvent, the mixture is polymerized by heating it for three hours to a 120‹ C., and for 24 hours to 180‹ C. The plasticizer acts as a lubricant and other resins may be used including stratyl resin all-stratyl A28-norsodyne 69-crystic 191- crystic 182-norsodyne 85.

Class 17(1) A shoe upper conforming machine having means for supporting an upright Veldtschoen, a plurality of grippers 11 to pull the upper U down 'to the last L, toe embracing wipers 13 to move downwardly and, on release of the upper by the grippers, to close so as to unge the upper into the crease angle between the last and a projecting portion of a sole member I to form a flange, and means for pressing together the sole margin and the flange, has a pad 2 to move downwardly with the wipers to press the upper against the last in the region of the toe cap line, and a band-like member 10 to move downwardly with the pad and perform a heightwise wiping action on the upper around the toe whilst shielding the upper from engagement with the edges of the wipers. The machine is generally similar to those described in Specifications 598,164 and 621,322, with heated wipers &c. The shaped rubber pad 2 is moved down yieldably with the wipers and engages and holds the upper before the wipers reach their lowest level, the flexible member 10 preventing marking of the upper by the heated wipers. Member 10 which is formed of heat resisting plastic material, e.g. hard rubber, is of U- shape and is chamfered at the lower edge 20. The member is positioned heightwise by engagement with plate 4 which carries pad 2, and is yieldably clamped to pad 2 by means of a rod 12 passing through the pad, springs 18 permitting the member to conform to the outline of the shoe. Member 10 extends below pad 2 and below the initial position of wipers 13 relative to the pad, and as it moves down wipes the upper and prevents contact of the wipers with the upper. When member 10 comes to rest the wipers continue to move downwardly, and finally close inwardly, just beneath member 10, to form the crease. Member 10 may be reinforced and held in a somewhat pointed condition by leaf springs pressing outwardly against its inner surfaces.
