IPC: B60R11/00
Filed: 1919-08-06
Abstract: 153,648. Cowey, L. E. Aug. 6, 1919. Addition to 123,904. Attachments for carrying and holding articles. -The parent Specification describes a bracket or support for speed indicators or similar instruments on which one end of the bracket is mounted on the handle-bar of a cycle and the other end is formed as a ring which is clamped over the stem of the instrument by means of a sleeve divided into two parts along a plane inclined to its axis. The two parts of the divided sleeve are forced firmly against the bracket ring by a screwed lock-nut. When this is slackened, the split sleeve can be rotated in order to vary the angle of inclination of the stem of the instrument relatively to the bracket. According to the present invention, the end b<1> of the bracket B instead of being secured to the handle-bar of a cycle is mounted in a conically-bored lug a<1> formed on a plate A, which is fixed by means of screw holes a to any convenient part of a motor or other vehicle. By slackening the nut b<3> the inclination of the bracket B can be varied as desired. The stem of a speed indicator, soundhorn, or other instrument is passed through the ring b, and is adjustably secured by means of the divided sleeve previously described.

Title: Chain terminated polycarbonates
IPC: C08G64/18
Filed: 1961-05-30
Abstract: Linear polycarbonates are chain-terminated by reaction with a monofunctional alcohol, mercaptan or silanol, the silanol being formed in situ by the hydrolysis of a monohalosilane. The polycarbonates are made by dissolving a diol in aqueous sodium hydroxide, adding an organic solvent for the polycarbonate resin, passing phosgene into the reaction mixture, adding up to 0.01 mole of the chain-terminator per mole of diol, and then agitating the reaction mixture until the polymerization is complete. A further portion of diol may be added to the partial reaction product of the diol and the phosgene. The chain-terminators may have the formula: (a) R-X-H where R is a hydrocarbon radical free of aliphatic unsaturation (e.g. alkyl, cycloalkyl or aralkyl) and X is oxygen and sulphur and is attached to an aliphatic or cycloaliphatic carbon atom; (b) <FORM:0965457/C3/1> where R is a hydrocarbon radical free of aliphatic unsaturation (e.g. alkyl, cycloalkyl or aryl), each R1 is an alkyl radical and n is 1-3; (c) <FORM:0965457/C3/2> where R is an alkylene or cycloalkylene group containing 2-9 carbon atoms and each R1 is hydrogen or an alkyl radical containing 1-4 carbon atoms; (d) H-(CF2CF2)n-CH2OH where n is 1-8; (e) <FORM:0965457/C3/3> where X is chlorine, bromine or iodine and each R is a hydrocarbon radical containing 1-16 carbon atoms (e.g. alkyl, cycloalkyl, phenyl or alkylphenyl). Preferred diols are bis-phenols of formula: <FORM:0965457/C3/4> where B is alkylene, alkylidene, aralkylene, oxygen or sulphonyl and each R is hydrogen, alkyl, cycloalkyl, aryl or halogen. The polycarbonate forming reaction is preferably effected in the presence of quaternary ammonium compound as catalyst. Examples describe the manufacture of chain-terminated bisphenol-A polycarbonates. The polycarbonate may be used in the manufacture of films, fibres, tubes, rod, bottle caps, gears, laminates and coating compositions.
