Title: Production of organosilicon compounds
Inventor: PIERPOINT EDWARD KEITH
IPC: C08G77/00
Filed: 1960-11-07
Abstract: Organosilicon compounds are made by reacting together a silicon compound containing a silicon-bonded hydrogen atom and an unsaturated compound in the presence of a complex of a platinous salt and an olefin.  The silicon reactant may be a halogenosilane, organohalogenosilane, polysilane, polysiloxane or polysilcarbane, in which the organic radicals may be alkyl, alkenyl, aryl or haloaryl radicals, but must contain at least 1 Si atom having at least 1 and not more than 2 H atoms bonded thereto, e.g. methyldichlorosilane, dimethylchlorosilane, trichlorosilane, diphenylsilane, methylphenylchlorosilane, 1:4-bis(dimethylsilyl) methylhydrogenpolysiloxanes and siloxanes containing both -Si(CH3)O-and -Si(CH3H,O- units.  The organic reactant can be any unsaturated compound except aliphatic amines, aldehydic compounds and compounds having a cyano group on an unsaturated C atom, and may be a purely organic compound or an organosilicon compound, numerous examples of which are given. The silicon compound may contain both the H and the unsaturated radical.  The catalysts specified are complexes of ethylene, propylene, butylene, cyclohexene and styrene with platinous chloride.  The reaction is preferably effected with the range of 10 DEG  to 150 DEG C. at normal or super-atmospheric pressure.  In examples, polymers were made (1, 2 and 7) by polymerizing methylphenylvinylsilane in presence of the platinum complexes, or (3, 10, 11 and 12) by reacting siloxanes containing Si-H with unsaturated compounds; and addition products were made by the above process from (4) methyldichlorosilane and vinylacetate; (5, 13) 1.3.5.7-tetramethylcyclo-tetrasiloxane and styrene or methylmethacrylate; (6, 8) methyldichlorosilane and allylcyanide or commercial diisobutylene; (9) trichlorosilane and commercial diisobutylene; and (14) methylphenyl-vinylchlorosilane and diphenylchlorosilane.

Abstract: 1,182,863. Measuring liquid level electrically. BENDIX CORP. Aug. 12, 1968 [Sept. 11, 1967], No.38496/68. Heading G1N. An electrical liquid-level gauge comprises means for establishing an electrical potential gradient e.g. a resistor, 28, extending from the minimum depth of liquid to be gauged to its maximum depth, an electrically conductive probe 18 situated in the liquid adjacent to the resistor and circuit means for determining and indicating the potential of the probe. By virtue of the ion currents flowing through the liquid between the probe and the resistor the probe potential is midway between that of the resistor at the liquid surface and that of the container, which defines the minimum liquid depth. Since the potential at the liquid surface is directly related to the depth of the liquid the probe potential maybe used to give a required indication. A detailed construction of the gauge, in which the resistor 28 is arranged in the form of a helix with the probe 18 extending along its axis, is described with reference to Figs. 1 and 2 (not shown).

Title: Improvements relating to a quick service bulb and quick service valve for graduated release valves
Inventor: SIMMONS ARTHUR WILLIAM
IPC: B60T15/30
Filed: 1962-10-11
Abstract: 1,019,714. Fluid pressure brakes. WESTING- HOUSE BRAKE AND SIGNAL CO. Ltd. Sept. 18, 1963 [Oct. 11, 1962], No. 38530/62. Heading F2F. A quick-service bulb having a quick-service valve for use with a graduated release valve 19 for a direct-release triple valve at 1 in a braking system is arranged so that a portion 9 of the quick-service bulb is rendered ineffective if, during reapplication of the brakes, pressure in the brake cylinder is in excess of a predetermined value. The bulb portion 9 connects through passages 13 and 16 with another bulb portion 3 with a passage 17 to the triple valve which, in the application position, connects the bulb portion 3 to the brake pipe and, in the release position, connects it to atmosphere. On one side of a diaphragm 5 a chamber 4 connects with the brake cylinder exhaust passage of the triple valve and a chamber 6 on the other side connects at 14 with the atmosphere. A stem 10 is pressed against the underside of the diaphragm 5 by a spring 7 and extends down, through a gland 8, to form a valve with a seating 12 which can close the passage 13 between the bulb portions 3 and 9 when the diaphragm 5 is depressed against the spring 7. With the brakes released and the triple valve in the release position there is no pressure in the chamber 4 so that the passage 13 is open. When the brakes are applied the triple valve connects the brake pipe with passage 17 and the brake pipe air flows quickly into bulb portions 3 and 9 giving normal quick-service operation. On release of the brakes the triple valve connects brake cylinder exhaust passage 20 to chamber 4 causing the diaphragm 5 and stem 10 to move down to close the valve 11/12 so that the bulb portion 9 does not vent as, simultaneously, the bulb portion 3 is connected to atmosphere. Subsequent partial release and application of the brakes gives rise to a very small drop in the brake pipe pressure as the bulb portion 9 remains closed and bulb action is limited to the portion 3. When the brakes are nearly completely released the brake cylinder pressure in the chamber 4 falls to an extent that the spring 7 can open the valve 11/12, putting the whole quick-service bulb ready for the next application of the brakes. The invention can also be applied to vacuum-operated brake systems.

Abstract: 1366303 Lubrication testing G A VINNICOMBE 11 Nov 1971 [11 Aug 1970] 38598/70 Heading G1S An apparatus for testing the lubricity of a fluid or the wear properties of a bearing material comprises a pair of relatively movable members each having a substantially plane bearing surface 4, 9, respectively, one of the members having an undercut 11 adjacent its bearing surface so that relative movement of the two members causes deformation adjacent the undercut as shown in Fig. 4 to produce a wedge 13 of fluid. In the embodiment of Figs. 1, 3 three pins 8 each having a pair of undercut bearing surfaces 9 are held stationary by a flexible spider 1 Fig. 2 (not shown). Two rotors 2 are driven by a shaft 5 and each have a bearing surface 4 engaging the pins. Lubricating fluid is contained in the chamber 12, and the pressure between the bearing surfaces is adjusted by a screw 10. In a modified form of the apparatus only one rotor is provided, and load is applied through an air thrust bearing. In another modification, the pins are carried by the rotors and a single stator is provided between the rotors. In another form, a planar rotor is set between two sets of stationary pins. In use the wear produced in the members during a run may be compared with the wear produced with a standard fluid if fluid testing, or with standard wearing surfaces if wear is being tested. Alternatively the friction may be measured during the tests by means of strain gauges 14 Fig. 2 (not shown) provided on the flexible spider 1. In this case, the friction is measured against speed, the apparatus is run at a constant speed for a pre-set time, and the friction again measured against speed.

Abstract: 1,112,327. Electrical control systems. LEUNA-WERKE "WALTER ULBRICHT" VEB. Sept.5, 1966, No.39644/66. Heading G1N. A control system for electrical apparatus enclosed in an atmosphere of a protective gas comprises means sensitive to the internal gas pressure to cut off the power supply in the event of a gas fault. As shown (Fig. 1), when the door of the housing is closed a switch 5 is operated to allow gas from a supply 1 to enter. The gas flow is measured at 3 and produces an electrical signal at 4 which is supplied to an AND gate 11. The internal gas pressure is measured at 8, and produces a signal at 9 which is also fed to gate 11. When both signals appear, the gate 11 initiates a timer 13 which closes the main supply 16 at the end of a predetermined period. If either input signal to the AND gate fails, timer 13 causes switch 16 to disconnect the power supply. In one modification (Fig. 4), the internal pressure gauge 8 initiates the timer 13 through a lower value preset switch 12. After a predetermined scavenging period, the timer 13 closes an exhaust valve 19 and the internal pressure rises to energise a higher value preset switch 15, which actuates the main supply switch 16. Other modifications are described.
