Title: Improvements relating to organopolysiloxanes
IPC: C08G77/06
Filed: 1960-01-08
Abstract: A benzene-soluble organopolysiloxane having an intrinsic viscosity in benzene, when measured at 25 DEG C., of at least 0,4 decilitre per gram, is composed of from 90 to 100 mol per cent of units of the formula RSiO 3/2 , any remaining units having the formula R1R11SiO, R1[CN(CH2)m] SiO, R111SiO 3/2 or CN(CH2)mSiO 3/2 , wherein R is an aryl radical, R1 and R11 are each an aryl, alkyl or alkenyl radical, R111 is a lower alkyl radical of 1 to 4 C atoms, and m is 2, 3, or 4. The polymers may be made by forming a prepolymer of the above unit or units, as by conventional hydrolysis or copolymerization, and heating the prepolymer, e.g. at 200 DEG  to 325 DEG C., in the presence of a solvent therefor and an alkaline rearrangement catalyst, e.g. an alkali metal hydroxide or silanolate, the concentration of the solvent during the reaction being at the most 30% of the total weight of the solvent and siloxane.  Solvents specified are diphenyl, diphenyloxide, methylphenylether, ethylphenylether, cyclohexane, benzonitrile, mesitylene, durene and m-dimethylbenzene.  In Examples (1 to 3), C6H5SiCl3 in ether was hydrolyzed with water at a temperature not exceeding 25 DEG C., and heated to yield a syrup to which benzene was added and the water was then removed azeotropically to yield a benzene solution of the prepolymer which contained residual silanol groups; diphenylether and KOH in methanol were added and the mixture was heated to 250 DEG C. to yield, after removal of ether, water and benzene, a white solid which, on purification to remove catalyst, yielded long white fibres. Other Examples describe (4) the preparation of silanol-free phenylsiloxane prepolymer; (5) the preparation of phenylsiloxane precopolymers and (C6H5SiO1-5)8 as a by-product; (6) the conversion of the pre-copolymers of (5) to the desired polymers; (7) the preparation of biphenyl- and naphthylsiloxane polymers; (8) the preparation of methyl-b -cyanoethylsiloxane polymer; (9) the preparation of the desired polymers using different solvents.  Uses: they may be dissolved in solvents, e.g. benzene, and used (i) to coat and insulate metal conductors, (ii) to render textiles, especially inorganic fibrous materials, heat resistant, (iii) for bonding surfaces together, (iv) as coating compositions by admixing therewith fillers, e.g. silicas (fume, aerogel and precipitated), C black.  A1 powder and TiO2, dyes, pigments and plasticizers; (v) in making laminates (see Group VIII) and (vi) for coating mufflers and tail pipes of cars, and ovens; the solutions may also be cast on flat surfaces to provide films for use as slot liners and as end turn winding insulation in motors; the polymers may be mixed with 10 to 50% (by wt.) of (C6H5SiO1,5)12 and used for moulding. U.S.A. Specification 2,482,276 is referred to.

Title: Electrical assembly of which a three phase generator forms one element
Inventor: LINDRE JAAN
IPC: H02J7/14
Filed: 1968-01-05
Abstract: 1,202,791. Vehicle electrical systems. FORD MOTOR CO. Ltd. 5 Jan., 1968, No. 749/68. Heading H2H. A vehicle electrical system comprising a threephase star-connected alternator 1 charging a battery 23 by way of a rectifier 11 is provided with a lamp 31 which is illuminated when the alternator is not charging but which is extinguished when the alternator output is above a predetermined limit. When the alternator is not being driven closure of an ignition switch 33 connects the lamp 31 to the battery 23 and, since a transistor 29 is non-conductive when the alternator 1 is not generating, the lamp 31 is illuminated. As the output of the alternator increases the base of the transistor receives an increasing signal from the star point of the alternator whereby the transistor becomes increasingly conductive. Thus, when the output of the alternator is above a predetermined amount, the transistor 29 is fully conductive and the lamp 31 extinguishes. The transistor may be replaced by a thermistor or the lamp connected across a diagonal of a resistance bridge one arm of which includes the transistor. Alternatively two arms of the bridge may be formed by batteries. If desired, a voltage regulator may be incorporated into the system in which ease the star point of the alternator is disconnected from the base of the transistor for part of each charging cycle.

Abstract: 425,070. Coin-freed liquid-dispensing apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, PEARSON, E. J. B., and STOPFORD, C. W., c /o General Electric Co., Wembley, Middlesex. Jan. 9, 1934, No. 830. [Class 27] [See also Groups XIII and XX] In apparatus for heating and storing water in a tank, means are provided for measuring the average temperature of water in the tank, and coin-freed means are arranged so that after insertion of a coin, hot water can be withdrawn up to an amount which reduces said average temperature by a predetermined amount. Cold water enters the tank, which has a heater 5 and thermostat 6, by inlet 9 and displaces hot water at 10. The average temperature in the tank is measured by a gas-filled tube extending the whole length of the tank, or by a rod 1 and tube 2, the rod being of non- expanding metal and the tube of brass. The coin-freed means comprises two rods 14, 15 hinged at 16 and both resting on the rod 1. On insertion of a coin, the rod 14 is locked and enables a tap to be opened to withdraw hot water. The entering cold water lowers the average temperature, whereon the rod 1 sinks carrying with it the rod 15 ; and when the latter has sunk through a predetermined angle, the tap automatically closes. Further water can be obtained only after the rod 15 has risen.

Title: Reversible step motor and method of controlling the same
Inventor: GUERIN YVES
IPC: H02K37/16
Filed: 1993-03-11
Abstract: The motor comprises a stator with three pole pieces having pole faces which define a cylindrical space, two windings which are magnetically coupled to the first and the second pole piece, and to the first and the third pole piece respectively, a rotor which is concentric with respect to the cylindrical space and which comprises a first permanent magnet, and a second permanent magnet coupled with the first magnet for holding the rotor, in the absence of any other influence, in a position in which the magnetic axis of the first magnet coincides with a rest axis. The field produced in the cylindrical space by the flow of a current in any one of the windings is at an obtuse angle to the rest axis. The rotor performs 360 DEG steps in response to pairs of current pulses, the first of which is applied to one of the windings and the second is applied to the other of the windings. Those pulses have always the same direction, and the order in which they are applied to the windings determines the direction of rotation of the rotor. The motor can be used in particular in an electronic timepiece.
