Title: Variable intensity illumination apparatus
IPC: H05B37/02
Filed: 1973-06-12
Abstract: 1391406 Lamp brightness control circuits SPERRY RAND CORP 12 June 1973 [29 June 1972] 27805/73 Heading H2H Variable intensity illumination apparatus comprises a lamp 49, a monostable multivibrator 35 and an astable multivibrator 33 coupled to drive the monostable multivibrator from a stable state into a quasi-stable state in response to a selected edge of the astable multivibrator output pulses. The brightness of the lamp may be increased by moving the adjustable arm of a potentiometer 53 towards the right thereby increasing and decreasing the series resistance of the resistance-capacitance networks of the multivibrators 33 and 35 respectively. This movement reduces both the pulse repetition frequency of the multivibrator 33 and the duration of the output pulses of the multivibrator 35. The trailing edges of the pulses from the multivibrator 33 trigger the multivibrator 35 and the output pulses from the complementary output terminal Q of the multivibrator 35 have an increased duration so that the lamp is bright. Opposite movement of the potentiometer arm reduces the duration of the pulses supplied to the lamp and the lamp is therefore dimmed. The multivibrators are formed as an integrated circuit and the leading edge of the astable multivibrator pulses may be used to trigger the monostable multivibrator.

Title: Manufacture of hardened artificial masses
IPC: C08G8/32
Filed: 1928-10-01
Abstract: 298,085. Groves, W. W., (I. G. Farbenindustrie Akt.-Ges.). Oct. 1, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 1 1928]. Boards and compound poper.-Phenolformaldehyde condensation products containing carboxylic groups are produced by reacting a phenolformaldehyde resin with a halogen fatty acid or its salt or by reacting a phenoxyfatty acid with formaldehyde or a substance yielding formaldehyde. Hardened masses are produced by heating an ammonium or amine salt of the resin acid with or without a polyhydric alcohol to above 100‹ C. A filling-material such as paper-pulp, asbestos, sawdust, wood-pulp, infusorial earth, or powdered horn may be mixed with the aqueous solution of the ammonium or amine salt of the resin carboxylic acid, the mixture being pressed in a mould and hardened by heat; or paper web may be impregnated with the aqueous solution, a number of such webs being superposed and formed into a mass by heating. The polyvalent alcohols mentioned are glycerine, glycol, mannitol, pentaerythritol, polyvinyl alcohol (made by saponification of polyvinyl acetate) and soluble carbohydrates. In the examples cresol-formaldehyde resin is dissolved in caustic soda and chloracetic acid is added, the reaction product being precipitated by hydrochloric acid, washed, and dissolved in ammonia solution; it may be used for impregnating paper pulp or animal or vegetable tissues or for preparing lacquers. A similar product may be obtained by using aqueous pryridine instead of ammonia. The condensation product of cresoxyacetic acid and paraformaldehyde in presence of hydrochloric acid is dissolved in aqueous methylamine. The condensation product of commercial tricresol and formaldehyde in presence of an alkali is mixed, additional alkali and sodium chloracetate is added; the product is precipitated by hydrochloric acid and dissolved in ammonia solution. The phenol-formaldehyde resin known as '' Bakelite A " is reacted with chloracetic acid and the product dissolved in ammonia solution; glycerine is added and the mixture is kneaded with paper pulp to a pasty mass, from which a part of the solution is removed by pressing, after which the mass is moulded and heated. The Specification as open to inspection under Sect. 91 (3) (a) states that the resin-carboxylic acid may be hardened by heating with a polyhydric alcohol to above 100‹ C. This subject-matter does not appear in the Specification as accepted.
Patent GB-701066-A (GB)
Title: Production of closed cell cellular bodies from thermo-plastic masses
IPC: C08J9/04
Filed: 1951-11-30
Abstract: Closed - cell cellular thermoplastic masses of e.g. polyvinyl chloride, polystyrene or cellulose acetate are made by dissolving gases in the hot mass under high pressure in a closed mould, heating the mass until it gelatinizes, reducing the pressure whilst preventing escape of material to obtain a 1/5 to 2/5 increase in volume, then cooling the mass and finally completely relieving the pressure.  Final expansion of the mass is obtained by reheating without pressure.  The gas may be forced into the powdered thermoplastic material or a blowing agent such as azoisobutyric dinitrile may be incorporated in it.  The material may be confined in hermetically sealed mould having a movable upper die, the mould being placed between the heated platens of a hydraulic press.  The die is raised to obtain the desired expansion.  Alternatively, a rigid mould or autoclave partly filled with the thermoplastic material and partly filled with an inert gas, such as nitrogen, under pressure, is used. Pressure is relieved to produce the desired expansion by allowing some of the inert gas to escape.  Specification 527,951 and 578,513 are referred to.ALSO:Closed cell cellular thermoplastic masses of, e.g. polyvinyl chloride, polystyrene or cellulose acetate, are made by dissolving gases in the hot mass under high pressure in a closed mould, heating the mass until it gelatinizes, reducing the pressure whilst preventing escape of material to obtain a 1/5 to 2/5 increase in volume, then cooling the mass and finally completely relieving the pressure.
