Title: Improvements in or relating to non permeable coatings
IPC: C08J7/048
Filed: 1933-03-21
Abstract: The gas-retaining qualities of heat-vulcanized rubber are improved by applying thereto a composition comprising a synthetic resin of the polyhydric alcohol-polybasic acid type diluted with glycerol or other polyhydroxy compound or compounds and gelatine. The diluting polyhydroxy compound may be added in the manufacture of the resin. The elasticity of the product may be improved by the addition of a drying oil, agar, starch acetate or cellulose esters.  The adhesion may be improved by the addition of an adhesive such as that described in Specification 395,430, [Group V].  The resistance to water of the composition after application to the rubber may be increased by treatment with formaldehyde. The coated rubber may be used in the manufacture of inner tubes for tyres, balls and air cushions and coated rubberized fabrics may be used for airship envelopes.  In examples, (1) a solution of gelatine in water is mixed with a condensation product of glycerol, succinic acid and phthalic anhydride; (2) a solution of a condensation product of glycerol, succinic acid and phthalic anhydride in glycerol is mixed with a solution of gelatin in water; (3) a solution of a condensation product of glycerol, triethanolamine, phthalic anhydride and m-butane-1-4-dicarboxylic acid in glycerol is mixed with gelatin and water; (4) a solution of a condensation product of polyglycerol, glycol, phthalic anhydride and N-butane-1,4-dicarboxylic acid in glycerol is mixed with a solution of gelatin in water to give coating compositions for rubber.  Specification 376,929, [Group V], is referred to.  The Provisional Specifications refer also to the use of compositions comprising a synthetic resin derived from a polyhydroxy compound and a polybasic acid diluted with glycerol (in the First Provisional Specification) and other polyhydroxy compounds (in the Second Provisional Specification) with or without the addition of a drying oil, agar, starch acetate, or cellulose esters.ALSO:Synthetic resins are prepared from polyhydric alcohols and polybasic acids with, if desired, an excess of polyhydric alcohol. In examples the following ingredients are condensed together (1) glycerol, succinic acid and phthalic anhydride; (3) glycerol, triethanolamine or glycol, phthalic anhydride and n-butane-1 : 4-dicarboxylic acid.ALSO:The gas-retaining qualities of heat-vulcanized rubber are improved by applying thereto a composition comprising a synthetic resin of the polyhydric alcohol-polybasic acid type diluted with glycerol or other polyhydroxy compounds and gelatine with or without the addition of a drying oil, agar, starch acetate or cellulose esters or an adhesive. The coating may be subsequently treated with formaldehyde to increase its resistance to water.

Title: Improvements in or relating to field time-base circuit arrangements
Inventor: ATTWOOD BRIAN ERNEST
IPC: H03K3/313
Filed: 1965-03-02
Abstract: 1,076,093. Semi-conductor saw-tooth generator circuits. MULLARD Ltd. Nov. 22, 1965 [March 2, 1965], No. 8849/65. Heading H3T. The saw-tooth drive voltage for the semiconductor output stage of a saw-tooth generator is converted into frequency modulated pulses before application to the output stage so as to operate the latter in a switching mode. As shown, the conversion is effected by a relaxation oscillator R1, C2, Ds fed from the output of the saw-tooth driving circuit RV1, C1, SW, the gap between the output pulses and thus the pulse frequency increasing as the drive voltage increases. If the breakdown voltage of the diode D s  is near to the peak drive voltage the frequency is very sensitive to drive voltage amplitude. If, however, the current through R1 and R2 approaches the diode holding current and if R2 is relatively large a component of width modulation is added. Resistor R2 serves to ensure that Ds does not operate during the fly-back but commences to operate immediately the scan recommences. Ds could be replaced by a unijunction device and SW may be a blocking oscillator or a PNPN device. The output stage operates in the manner described in Specification 1,076,092.
