Title: Sound absorbtion materials
IPC: E04B1/86
Filed: 1975-11-11
Abstract: 1514530 Non-woven structure; Sound absorption material MONTEDISON SpA 11 Nov 1975 [14 Nov 1974] 46452/75 Headings D1R and D2B  A sound absorption material having an apparent density of 0.04 to 0.5g/cc comprises thermoplastic polymer fibrils having a surface area greater than 1m<SP>2</SP>/g held together by a binder, the weight ratio of fibrils: binder being 95:5 to 50:50. The fibril forming polymer may be polypropylene, an ethylenepropylene or ethylene-alkylacrylate copolymer, polyamide, polystyrene, polyoxymethylene, polyacrylonitrile, polyacrylate or polyvinyl chloride. It may contain kaolin, silicon, calcium sulphate, talc, calcium carbonate or titanium oxide as filler. The binder may be a thermoplastic polymer of lower melting point than the fibrils, e.g. polyethylene, polyvinyl alcohol or polyvinyl acetate, epoxy resin, unsaturated resin or an animal or vegetable glue. It may be incorporated as fibrils (ex. 1-4) 50-500 micron particles (5) or an aqueous or non aqueous solution or dispersion (6). It is mixed with the fibrils in the dry state, e.g. in a mixer or carding machine, or in the wet state, e.g. by stirring or disc refining an aqueous dispersion of polypropylene fibrils and polyethylene binder fibrils (ex. 2, 3). The dry or water dispersed mixture is introduced into containers formed of fine metal mesh heated to remove the water (if any) and soften the binder and optionally pressed. Flexible, semi rigid and rigid panels may be obtained.

Filed: 1970-09-30
Abstract: 1356926 Graft polymerization process BP CHEMICALS Ltd 8 Sept 1971 [30 Sept 1970] 46602/70 Heading C3G A rubber reinforced polymer is produced by mixing the rubber in the form of an aqueous latex with monomeric material in the presence of a water soluble cellulose derivative, destroying the stability of the rubber latex, allowing the rubber particles protected by said derivative to pass into the monomeric material and polymerizing said material as a suspension in water stabilized by the addition of a suspension stabilizer. The latex may be stabilized by a carboxylic acid salt emulsifying agent, which is later destroyed by addition of a relatively strong acid, or by a salt of a heavy metal or aluminium. In the examples, the rubber, monomer, cellulose derivative, emulsifying agent and emulsifier destroying agent are as follows; (a) polybutadiene, styrene and/or methyl methacrylate, or styrene and acrylonitrile, hydroxyethyl cellulose, rosin and fatty acid salts and phosphoric acid or acetic acid, the suspending agent added later being hydroxyethyl cellulose, or polyvinyl alcohol and mineral oil being added in one instance before the phosphoric acid; (b) polychloroprene, styrene, hydroxyethyl cellulose, rosin acid salt, sodium salt of alkyl aryl polyether sulphonate and of methylene dinaphthalene sulphonic acid and acetic acid, polyvinyl alcohol being added later as suspending agent; and (c) butadiene-acrylonitrile rubber, styrene, hydroxyethyl cellulose, salts of dodecylbenzene sulphonic acid and naphthalene formaldehyde sulphonate and acetic acid, polyvinyl alcohol being used as suspending agent.

Title: An Electrically Controlled Time Signal-Producing System
IPC: G04C21/06
Filed: 1967-10-13
Abstract: 1,164,728. Time switches; momentary-contact switches. FABRIQUE D'HORLOGERIE LA VEDETTE and JAZ S.A. 13 Oct., 1967 [25 Oct., 1966], No. 46883/67. Heading H1N. [Also in Division G3] A switch operated by a timepiece movement for energizing an electronic circuit to produce signals at predetermined times, e.g. for actuating an electromagnetic clock striking mechanism, comprises a shaft 66, Fig. 8, driven by the timepiece movement and carrying a cam 67 against which is urged by a spring 74 a pin 68 on a trigger 69 pivoted on a shaft 70 and carrying a switch contact 10. At predetermined intervals the cam 67 permits the pin 68 to fall abruptly so that the contact 10 engages the abler switch contact 11, on a resilient blade 72 so urged by a lateral projection 71 on the cam 67, when the latter is in a switch operating position, that the contact 11 can be engaged by the moving contact 10. The duration of each engagement of the contacts 10, 11 is predetermined by controlling the movement of the trigger 69 by means of a toothed sector 78 thereon which rotates a pinion 79 carrying a vane 80 retarded by air resistance, inertia, magnetic braking or other means. When the trigger 69 is raised from its lowermost position by the cam 67 the projection 71 no longer displaces the blade 72, and the contact 10 passes the contact 11 without engaging it. In an alternative construction the shaft 66, Fig. 10, carries a cam 83 having an outer section acting upon the pin 68 on the trigger 69 and an inner section against which is drawn by a spring 88 a projection 87 on a pivoted lever 84 carrying the contact 11. Before the trigger 69 is permitted to fall the cam 83 permits the lever 84 to turn anticlockwise so that when contact 10 moves it engages the contact 11; and before the trigger 69 is lifted from its lowest position the cam 83 rotates the lever 84 clockwise so that the contacts 10, 11 do not engage when the trigger 69 is raised. The fall of the trigger 69 is time controlled by an escapement comprising a balance 93, a return spring 98, and pallets 95, 96 cooperating with teeth 97 on the trigger 69. The switch can be rendered inoperative during desired periods by adjustment of a cam 114 driven by the timepiece movement and arranged to prevent falling of the trigger 69 during such periods.

A process for preparing a water-dispersible meat (the term "meat" includes poultry and fish) flavour and aroma composition comprise liquefying the meat by heating it in the presence of moisture above 330‹F. and at superatmospheric autogenous pressure to hydrolyse the meat protein so that visible discrete meat fibres substantially disappear and immediately cooling said liquified meat to a temperature less than the atmospheric boiling point of the liquified meat. The liquified meat may be concentrated or spray dried to a powder. The meat may be obtained from cattle, hogs, sheep, chicken and fish and may be beef, pork, skin, liver, cheeks, tongues and hearts. The meat may be ground and charged together with water, salt, lactic acid, oleaginous material (e.g. beef tallow, lard and cottonseed oil) and emulsifiers, into a steam or electrically heated autoclave, heated, cooled, homogenised and spray dried.

Various unsaturated monomers may be used to cross-link the polyester resin, including vinyl compounds such as styrene, alphamethyl styrene, vinyl-toluene, vinyl acetate, diallyl phthalate, diacetone acrylamide, methyl acrylate, methyl methacrylate, chlorostyrene, divinyl benzene, triallyl cyanurate, and mixtures thereof. 5 to 10% by weight of hexamethylmethoxy melamine may be used to aid copolymerisation and the blend of resin and cross-linking monomer will preferably include suitable catalyst such as peroxy compounds, and accelerators, as well as flow control agents. A solution of the cross-linked resin is applied to paper by dipping or spreading. Optionally a non-woven sheet of a spin-bonded polyester fibre is bonded to the back of 'the polyester resin-impregnated sheet prior to applying hotmelt glue. After curing, the polyester resinimpregnated sheet is coated with the hot-melt glue using a gravure roll to a thickness of 10-12 microns. The hot melt glue may be a polyamide, ethylene-vinyl acetate copolymer or polyvinyl acetate. The edging material is cut into strips and then may be applied to any suitable substrates such as plywood, gypsum board, lumber, particle board, hardwood, metal, flakeboard, cement asbestos board, or composition board.
