Title: Improvements in or relating to the manufacture of new saponaceous materials from organic isocolloids containing unsaturated high molecular acids
IPC: C11D9/02
Filed: 1928-05-08
Abstract: 321,723. Auer, L. May 8, 1928. Divided on 321,691. Fatty oils; soaps, processes for making.-Fatty oils are heated at elevated pressure, in the absence of water, with alkali metals, their oxides or hydroxides, with or without an alkaline earth peroxide, to yield saponaceous compounds to be used as such or in the form of an aqueous emulsion in the manufacture of soap, or after vulcanization as a substitute for rubber. The reaction mass may be treated with radiations, e.g. X-rays, or with gases, e.g. nitrogen, carbon dioxide, oxygen, and may be vulcanized by treating with sulphur dioxide and hydrogen sulphide alternately, using benzoquinone as accelerator or by a separate vulcanization process. The dissolution of the alkali metals or compounds may be assisted by addition of metal-free organic compounds such as phenols, arylamines, hydrocarbons, ketones, formaldehyde, benzidine, or quinoline. Specifications 14571/14 and 321,722 are referred to.

Filed: 1971-07-05
Abstract: 1361272 Light-sensitive polymeric materials INTERNATIONAL BUSINESS MACHINES CORP 5 July 1971 [31 Aug 1970] 31355/71 Headings C3P and C3R [Also in Division G2] Light-sensitive polymeric materials comprise a cinnamoyl, substituted cinnamoyl or diazoketo-naphthalenesulphonyl derivative of a polymer which is formed by addition copolymerization of a vinyl ketone of the formula and an acrylate ester of the formula in the presence of an alkaline agent. In the above formulae R is hydrogen or α monovalent hydrocarbon group with 1 to 10 carbon atoms having no aliphatic unsaturation (e.g. alkyl, cyclohexyl or phenyl); R<SP>111</SP> is a monovalent hydrocarbon group, preferably alkyl, cycloalkyl or phenyl; R<SP>11</SP> is hydrogen or C 1 -C 5  alkyl; and R<SP>1</SP> is hydrogen, alkyl, cycloalkyl or phenyl. The base polymers are normally prepared by polymerizing the monomers in an inert diluent and in the presence of the alkaline agent e.g. sodium methoxide. The base polymers are believed to contain repeating units of the structures: and the light-sensitive derivatives repeating units of the structures:  where R, R<SP>1</SP>, R<SP>11</SP> and R<SP>111</SP> are as defined above and D is a cinnamoyl or substituted cinnamoyl radical or a quinone diazide sulphonyl radical derived from a diazo-keto-naphthalenesulphonic acid. The base polymers are converted to the light-sensitive derivatives by reaction with an appropriate acylating agent, e.g. cinnamoyl chloride, o-chlorocinnamoyl chloride, m-nitrocinnamoyl chloride, α-phenylcinnamoyl chloride, naphthaquinone-1,2-diazide-5-sulphonyl chloride and naphthaquinone-1-diazo-4-sulphonyl chloride. The polymers are used in lightsensitive layers of image-forming elements, optionally in combination with an alkalisoluble resin such as shellac, a styrene/maleic anhydride copolymer or a phenol-formaldehyde resin. In Examples V and VI a m-cresol/formaldehyde resin is used with the light-sensitive polymer.

Abstract: 372,238. Counters of scoring-type. LEONIDAS WATCH FACTORY, Vve Constant Jeanneret-Droz, St. Imier, Berne, Switzerland. Nov. 13, 1931, No. 31490. Convention date, Dec. 17, 1930. [Class 106 (i).] A watch-shaped golf scorer with dials and pointers in which the adjusted numerals are made visible behind small windows in the dial, by means of radially arranged numeral wheels operated by a pusher pin is characterized in that the wheel axes, arranged parallel to the baseplate are seated within a groove concentrically arranged with regard to the central pointer arbor. An operating or pusher pin 12, when depressed by the operator, actuates a pivoted plate lever 34, and by means of a link 32 and pin 28 rotates a ratchet wheel 27 through one step. The ratchet wheel engages a pin 48, Fig. 3, on a pair of spring-controlled levers 45, 47, and by means of a fork 53 and sliding pawl 51 rotates the relevant numeral wheel 3 through one step to display the next numeral through the dial plate. The arbors of the numeral wheels are mounted in a concentric groove 4<2>. The operating pin 12 carries a pinion 14 engaging a gear wheel 15 so that by rotating the operating pin the sliding pawl 51 may be brought into co-operation with any of the numeral wheels 3, at the same time setting a pointer 23 to indicate the relevant numeral wheel. A restoring plate 18, Figs. 3 and 4, which is also rotated by the rotation of the operator pin, actuates by means of a bevelled edge 54 and a spring 55, the heart hammers 7, Fig. 4, for zeroizing the numeral wheels.
