Patent GB-618444-A (GB)
Title: Improvements relating to valve-controlling mechanism particularly for liquid-filling nozzles
IPC: B67D7/48
Filed: 1946-05-10
Abstract: 618,444. Valves. TECALEMIT, Ltd., and LE CLAIR, C. C. S. May 10, 1946, Nos. 14226 and 15426. [Class 135] In a nozzle device, e.g. for filling liquid fuel tanks, having a liquid supply valve manually actuated through mechanism incorporating a toggle device and a chamber connected to an extraneous suction pump or other vacuumproducing means and to an air passage having an open outer end near the outlet of the nozzle, the vacuum produced in the chamber, when the liquid level in the tank rises above the open outer end of the air passage, acts on a flexible member to collapse the toggle device and to bring about closure of the supply valve. The operating handle 48, Fig. 5, abuts against a shaft 60 carrying a pivoted toggle link 65 engaging the stem 55 of the liquid supply valve 54 which controls liquid flow through a passage 40 to a nozzle extension 41, Fig. 6. A bracket 75 sliding on the shaft 60 is rigidly linked to the stem 55 and carries a seating member 76 for a vacuum valve 84 connected to an air valve 81 and controlling the communication between the chamber 53 and a flexible pipe 89 connected to the vacuum pump. The chamber 53 is normally in free communication with the atmosphere through the air valve and also through the air passage 93, 42 which has an open end near the nozzle outlet. Movement of the handle 48 to open the supply valve and fill the tank shuts the air valve 81 and opens the vacuum valve 84. Owing to the restricted aperture in the seating member 76, the pressure in the chamber 53 -remains substantially atmospheric until the liquid level in the tank rises above the open end of the air passage 42, Fig. 6. The resulting pressure drop in the chamber then causes a bellows 86 to displace the toggle link 65 and the supply valve is spring-closed against the action of a dashpot 59. Simultaneously, the vacuum valve closes and the air valve opens and any liquid in the pipe 42 drains into the tank. Release of the handle 48 allows the toggle link to be returned by a spring to its operative position. In a simplified construction, the air valve is dispensed with and the bellows is replaced by a diaphragm. Specification 524,840 is referred to.

Filed: 1970-03-24
Abstract: 1284631 Knitting-machines WILDT MELLOR BROMLEY Ltd 19 April 1971 [24 March 1970] 14244/70 Heading D1C A needle selection arrangement similar to that described in Specification 1029373 in which spring jacks 5 are pressed by pressers 8 movable by raising or lowering cams so that a patterning butt 9 or 9' co-operates with a different pattern disc, includes a modified lowering cam. At a height selection station the lowering cam 18 is positioned to act on the butt 15 above and spaced from the rail 16 to bring it to engage the top of the rail. The station also includes a raising cam 17 and a slatted guide 20, operative if selection is not required. The cams and guide are mounted on individual slides 22-24. Pegs 26, 27 on the cam slides co-operate with a pivoted notched disc 28 so that movement of one to the operative position renders the other inoperative. Guide 20 is mounted further forward on its slide, which has a peg 32 cooperating with slide projections 30, 31, so that when projected it displaces the inoperative cam slightly which withdraws the operative cam a similar amount. The slides are moved at the dictates of pattern mechanism via bell cranks e.g. 24b which are locked in operative position by a latch 25 as described in Specification 1284632.

Abstract: 141,232. Vickers, Ltd., and Baerlocher, F. R. June 5, 1919. Transformers. - In transformers intended for intermittent use during short periods, such as the auto-transformers used for starting alternating-current motors, the cores are composed of plain iron castings bolted together so as to form a central stem and an outside portion, leaving a space for the windings between them. In the construction shown in Fig. 3, two annular castings united by bolts B constitute a hollow stem A<1> and an outside portion A<2>. The winding occupies the space C. In another construction, one casting is a deep cup with a central bolt, and the other casting is a flat cover which closes the cup and touches the bolt. In a two-phase transformer, Figs. 6 and 8, two end castings A<6> butt against a middle casting A', leaving space for two windings C<2>, C<3>. Threephase cores may be similarly constructed. Cast iron of high electrical resistance may be chosen, and a fire-proof material such as enamel may be used to insulate the windings. The castings may have ventilating holes, or may be immersed in oil.

Abstract: Polyorganohalosilanes are prepared by reacting at an elevated temperature an organic compound containing a double bond between adjacent carbon atoms, e.g. a hydrocarbon, with an organohalosilane having hydrogen and halogen atoms directly attached to silicon.  The reaction temperature may be below 600 DEG  C., e.g. between 200 DEG and 550 DEG  C.  The preferred temperature range when using an olelinic hydrocarbon is between 200 DEG  and 300 DEG  C., and when using an aromatic hydrocarbon between 300 DEG  and 550 DEG  C. Super-atmospheric pressures may be employed, e.g. at least 100 or 200 pounds per square inch.  Suitable organohalosilanes given are phenyldibromo-, ethylmethylchloro-, propyldichloro-, methyldichloro-, octadecyldichloro-, ethyldibromo- and p-methylphenyldichloro-silanes. Suitable hydrocarbons may contain one or more double bonds and may be aliphatic, alicyclic, aromatic or mixed aliphatic-aromatic hydrocarbons, e.g. ethylene, propylene, butene, hexene, octene, decene, tetradecene, octadecene, cyclohexene, styrene, butadiene, hexdiene, unvulcanized rubber, benzene or toluene.  Olefinic hydrocarbons may be formed in situ by employing saturated alkyl halides instead of a hydrocarbon containing a double bond.  In examples: methylethyl-, phenylethyl-, phenylpropyl-, methylpropyl-, phenylmethyl-, methyl-n - octyl-, methyl - 2 - octyl -, methyloctadecyldichlorosilanes, methylphenylpropyl- and diethylpropyl-chlorosilanes are prepared.  Similarly ethylpropyl- and ethyloctadecyl-dichlorosilanes diphenylpropyl chlorosilane and methylpropyl- and methyldodecyl-dibromosilanes may be prepared.ALSO:Polyorganohalosilanes are prepared by reacting at an elevated temperature unvulcanized rubber and an organohalosilane having hydrogen and halogen atoms directly attached to silicon.

[Also in Group XVII] A liquid or paste-filled container of plasticised thermoplastic material, e.g. p.v.c., has its inner walls coated with a thin layer of an oily substance, e.g. liquid paraffin, to isolate the plasticiser from the liquid or paste. If the container has double walls, an additional layer of oily substance may be introduced between the walls. The coating may be applied to the sheet material from which the container is formed or, in the case of containers formed by filling and subdividing a length of extruded tubing, the latter may be coated internally before filling by introducing a small quantity of the oily substance at one end and passing the tubing through compression rollers so that the substance is caused to flow through the tubing to the other end. Alternatively, the tubing may be inclined upwardly and the substance introduced at the lower end which is then connected to means for filling the tubing with liquid or paste under gravity or other pressure, the filling material pushing the substance before it as it fills the tubing. The oil may be heated to a temperature below the softening point of the thermoplastic material to facilitate its application. Specification 599,174, [Group XVII], is referred to in the Provisional Specification.
