Title: Improvements in or relating to the manufacture of pure retort carbon
IPC: C01B31/00
Filed: 1921-02-07
Abstract: 158,891. Szarvasy, I. Feb. 28, 1914, [Convention date]. Carbon; hydrogen.-Pure retort-carbon is produced by decomposing methane in an internallyheated retort containing pieces of carbon obtained in a previous operation. The decomposition is preferably effected in a tube-furnace. inclined slightly to the horizontal so that the carbon filling fed in at the upper end is discharged automatically at the lower when the tube is rotated. The pieces are thus also kept in motion so that they do not become joined together by the carbon deposited. The tube is heated internally, either by the passage of an electric current through the carbon pieces, or by burning therein hydrogen or some of the methane when an oxidizing gas such as air must be supplied. The heating of the tube, when this is done by combustion of hydrogen or methane, and the decomposition of the methane, may be effected alternately. The hydrogen produced by the decomposition may be used to heat the methane before it is supplied to the furnace. Specification 15071/09 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) is not confined to an internally heated retort. This subject-matter does not appear in the Specification as accepted.

Filed: 1942-04-02
Abstract: 556,438. Electricallyreleased switches. ARROW ELECTRIC SWITCHES, Ltd. April 2, 1942, No. 4394. Convention date, April 12, 1941. [Class 38 (v)] A thermally-released circuit-breaker which can be operated manually on and off by a snap-action spring, comprises a pair of movable spring-contacts 44, 46 arranged one behind the other and in separate compartments of an insulating base 10. The hand-lever 12 is pivoted by means of pin 16 guided in slots 18 in the walls of recesses 10s and has a hooked end anchoring one end of a dead-centre spring 20, the other end of. which is fixed to the yoke of a U-shaped member 22. The free ends of member 22 are bifurcated at 22a to engage holes on either side of a part 26b on an adjustment plate 26. A lever 30 pivoted at 28 to member 22 is formed with a detent surface 32 engageable with a bimetal member 34, and with a part 38 adapted to engage a guided insulating plate 40. To close the contacts, by moving from the Fig. 1 to the Fig. 2 position, the lever 30 first moves with member 22 until its surface 32 engages the bimetal 34 and then rotates clockwise using 32 as a fulcrum-point, to raise plate 40. When 34 deflects on overload, the springiness of the contacts causes them to open and return lever 30 to the Fig. 1 position. An adjustment which avoids stressing the bimetal, is provided by means of a screwed rod 80 which moves plate 26, and hence the mechanism itsself, bodily up or down so as to vary its position with respect to the strip. The latter and contact 44 are secured by means of a hollow rivet 50 and a terminal screw 51 therein is connected to one end of a heater coil 60 in a heat-casing 62. The other end of coil 60 is connected to a circuit terminal so as to carry the load in one of the poles.. A terminal 54 and one similar to 50 for contact 44 constitute terminals for the other pole.

Abstract: 1365511 Lift tracks CONVEYANCER Ltd 4 May 1972 [11 Feb 1971] 4438/71 Heading B8H [Also in Division H2] A system for returning energy to the battery (not shown) of, for example, an industrial lift truck, comprises an electric motor 1 supplied by the battery and adapted to drive an hydraulic pump 8, and control valves 15, 20 which direct hydraulic fluid from the pump to a jack 16 of the truck or allow fluid to return from the jack to the pump to drive it and the motor so that the motor restores energy to the battery. In order to raise the jack, a lever associated with the valve 15 is moved to close contacts 2 and set the swash plate angle of the pump by means of an actuator 21. The motor 1 therefore drives the pump 8 which supplies fluid from a reservoir 9 via valves 10, 15, 14, 18 to the jack. To lower the jack, the lever is moved to open a diverter valve 20 and to set the valve 15 so that as the potential energy of the jack drives the pump the fluid is returned via conduits 13, 19 to the reservoir. The lever also causes opening of the contacts 2 and changes over a switch 6 connected between series and shunt field coils 3 and 5 respectively. The pump therefore drives the armature 4 of the motor 1 as a generator and supplies charging current to the battery via a diode or thyristor 7.

Title: Fluorine-containing silanes and their hydrolysis products
IPC: C08G77/24
Filed: 1956-02-14
Abstract: The invention comprises silanes of the general formula <FORM:0802358/IV (a)/1> where R is monovalent hydrocarbon radical free from aliphatic unsaturation, one X is chlorine or fluorine, the other being CF3-, C2F5-, CF2=CF-, or CFCl=CF-, Y is a halogen and n is 0, 1 or 2, and their corresponding siloxanes.  The silanes are prepared by reacting vinyl silanes of the formula CH2=CHSiRnY3-n with the appropriate ethylenic fluorocarbon such as perfluoropropene, perfluorobutene, perfluorobutadiene, 1-chloro-1,2,3,4,4 - pentafluorobutadiene, 1,4 - dichloro-1,2,3,4 - tetrafluorobutadiene, 1 - chloro - pentafluoropropene and 1 - chloroheptafluorobutene.  The reaction is best effected under pressure and at a temperature of at least 125 DEG  C.  Mixtures of isomers are usually produced. Examples of the R groups are methyl, octadecyl, phenyl, benzyl and xenyl.  The siloxanes are prepared by hydrolysing the silanes, if desired, in the presence of an inert solvent such as benzene, toluene or ether.  They may be copolymerized with other siloxanes by cohydrolysing the corresponding silanes or by catalytic copolymerization.  The polymers may be made in the form of liquids, greases, elastomers or resins, the copolymers with dimethylsiloxanes being particularly suitable for compounding with vulcanizing agents, such as organic peroxides, and fillers and curing to elastomers.  In the examples: (1) perfluorobutene-1,2 is reacted with ViMeSiCl2 to give a mixture of the isomers <FORM:0802358/IV (a)/2> On hydrolysis, an oily copolymer is produced.  (2) Perfluorobutadiene-1,3 is reacted with ViMeSiCl2 to give the compound <FORM:0802358/IV (a)/3> The corresponding liquid siloxane is produced by hydrolysis.  (3) The compound <FORM:0802358/IV (a)/4> is prepared from ViMeSiCl2 and 1,4-dichloro-1,2,3,4-tetrafluorobutadiene-1,3, and is hydrolysed to a liquid siloxane.  (4) The compound <FORM:0802358/IV (a)/5> is obtained from perfluoropropene and ViEtSiCl2 and is hydrolysed to a liquid siloxane.
