Title: Foamable styrene polymer compositions and production thereof
Inventor: BEAULIEU RAYMOND DENNIS
IPC: C08J9/00
Filed: 1962-10-10
Abstract: Foamed polystyrene is produced from compositions which compromise (a) a styrene polymer (as defined), (b) a volatile non-reactive organic foaming agent of boiling point between 10 DEG C. and the softening point of the styrene polymer and which has little or no solvent action on the polymer, and (c) a minor proportion of a three-component system comprising (1) an acid salt of alkali metal, alkaline earth metal (including magnesium) or ammonium polyacid phosphates, (2) a neutral salt of an alkali metal or alkaline earth metal (including magnesium) of a mono-or polycarboxylic acid, and (3) an alkali metal, alkaline earth metal (including magnesium) or ammonium bicarbonate or carbonate.  The foamable composition may comprise 92-95 parts of (a), 8 to 5 parts of (b), and a minor amount of (c) wherein said components are in the ratio 0.20 to 0.80 parts of acid phosphate salt, 0.50 to 1.00 parts neutral salt, and 0.20 to 0.60 parts of bicarbonate/carbonate.  The three component system may be present in amount 0.5 to 5.0 parts per 100 parts of the combination of styrene polymer and foaming agent but preferably 0.9 to 2.4 parts per 100 parts. The styrene polymer may be a homopolymer of a styrene or copolymer thereof but containing at least 50% of said styrene and having M.W. of 40,000 to 80,000. The styrene may be copolymerized with conjugated 1,3-dienes, e.g. butadiene or isoprene, a  and b  unsaturated carboxylic acids and derivatives thereof, e.g. acrylic acid, methyl, ethyl, butyl and 2-ethylhexyl acrylates, acrylamide and acrylonitrile and the corresponding methacrylic acid derivatives. Blends of the styrene polymer with other polymers may also be used, e.g. styrene polymer and rubbery diene polymer or a composition obtained by polymerizing styrene monomer in the presence of a rubbery diene polymer. All or part of the styrene may be replaced by a -methyl styrene, o-, m-, p-methyl and ethyl styrenes or 2,4-dimethyl styrene. The foaming agent is preferably an aliphatic hydrocarbon of boiling range 10 DEG  to 80 DEG C., e.g. pentane, hexane, heptane, cyclopentane, cyclopentadiene and petroleum ether, but may also be specified low boiling alcohols, aldehydes, ketones, esters, ethers, chlorohydrocarbons and chlorofluoroalkanes or mixtures thereof. The three component systems used specifically, comprise monobasic sodium, calcium or ammonium phosphate, sodium citrate or potassium sodium tartrate and sodium bicarbonate, the preferred system being monobasic sodium phosphate, sodium citrate, and sodium bicarbonate. Other constituents for the three component system are also specifically mentioned including acid phosphate salts obtained by partially neutralising polybasic phosphoric acid such as ortho and pyro phosphoric acid with hydroxide. Foamed products may be made by extruding the composition at elevated temperature and pressure, e.g. 120 DEG  to 205 DEG C. and at a mechanical pressure of 150 to 3200 p.s.i.

Title: Improved control system for a power transmission mechanism
IPC: F16H47/08
Filed: 1957-12-11
Abstract: 819,418. Endless track vehicle steering gear. GENERAL MOTORS CORPORATION. Dec. 11, 1957 [Dec. 28, 1956], No. 38496/57. Class 79(2) [Also in Groups XXIV] A transmission for a tracked vehicle comprises a torque converter 10, Fig. 1, driving a three speed unit 11 which in turn drives through a cross-shaft 12 a pair of reversing units 14, 15 for a p a i r of driven shafts 72. The three speed unit 11 comprises two epicyclic trains the annulus gears of which are braked at 39, 44 to give low speed and intermediate speed respectively whilst a direct drive is obtained by a clutch 48. The reversing units 14 15 each comprise two epicyclic trains, the annulus of one being held by a brake 78 for forward drive whilst the carrier of the other is held for reverse drive by a brake 67. Each output shaft 72 is also provided with a brake 81. The brakes 39, 44 and clutch 48 of the three speed gear are operated by pressure fluid to actuating pistons under control of a manually operable selector valve 121, Fig. 2, movable into neutral, low, intermediate or high positions. The pressure fluid is supplied from a pump 93 through a regulating valve 101 to a supply line 104 and to the converter 10. The line 104 also supplies pressure fluid to operate the forward and reverse brakes of the reversing units 14, 15 under control of selector valves 167, 171, Fig. 3, respectively. The supply to the selector valves 167, 171 is also controlled by a neutral control valve 161 which has two valve members 182, 183 normally allowing the free passage of the pressure fluid to the selector valves 167, 171 respectively. Pressure fluid is also supplied through an orifice restriction 194 in valve member 183 to a line 174 leading to a pressure release valve 173 which is controlled by the manual actuation of the respective one of the brakes 81. Operation of this brake moves an actuating ring 349 axially against the plates of brake 81 and in so doing opens the valve 173 to relieve the pressure in line 174. This relief of pressure causes valve member 183 to move to close off the supply to selector valve 171 and exhaust the latter Thus neither the forward or reverse brake can be engaged whilst the respective brake 81 is operating. The valve member 182 of the neutral control valve 161 is controlled by the brake 81 associated with the other reversing unit to cut off the pressure supply to the selector valve 167 when this brake is applied. Thus the two output shafts 72 are separately controlled for forward or reverse drive or braking to the vehicle tracks for steering control in addition to normal forward and reverse driving. Trimmer valves 166, 169 are provided associated with the selector valves 167, 171 to regulate the rise in pressure in the lines supplying them.
