Filed: 1960-05-17
Abstract: 952,460. Joint-making packing; pipe jonts. MARENGO S.p.A. May 17, 1960 [July 20, 1959], No. 17426/60. Headings F2B and F2G. A gasket for a pipe joint, preferably where the pipes are glass-lined, is constituted by a fluorocarbon resin, such as polytetrafluoroethylene or polychlorotrifluoroethylene, enveloping a core of compressible material, the joint-making surfaces of the gasket being treated with a solution of anhydrous ammonia and metallic sodium to increase the frictional resistances of such surfaces in engagement with the parts of the pipes being joined. The gasket is made from a tape 11 which is formed to make it take up the form of a closed ring of U-shaped cross-section, the contacting edges being buttwelded together; welding is effected by disposing the ends of the tape between heated pressure blocks which extend for a substantial distance on either side of the join to minimise the reduction in thickness at the weld. One surface of the ring, namely that which in use is to provide the jointing surfaces, is then roughened by treating it with the above-mentioned solution. After washing, the treated ring is finally assembled about an inner core formed of one or more rings. The rings 17, 18, 19 may be of asbestos with the central ring harder than the outer rings. As described in U.S.A. Specification 2,580,546, the annular core may be formed of corrugated metal with or without asbestos in the corrugations, rubber, ebonite, spirallywound steel ribbon interposed with asbestos strip, or compressed asbestos covered with soft woven asbestos cloth. Specification 765,284 also is referred to.

Title: A Method of and Means for Hydraulically Weighing Loads Suspended from Cranes.
Inventor: HANSER CHARLES ALFRED
IPC: G01G19/16
Filed: 1919-07-14
Abstract: 129,981. Hanser, C. A. July 19, 1918, [Convention date]. Apparatus fitted to cranes; hydrostatic apparatus.-Relates to hydraulic means for weighing loads suspended on cranes before or after hoisting or when arrested during the hoisting operations, and comprises means for temporarily transferring the weight of the load (for the purpose of weighing only) to a carrying device which is hydraulically mounted on a suspension device connected to the crane. The invention is described in connexion with a crane employing a grab which is operated by four cables, namely two hoisting cables 28 normally bearing the main part. of the load and two gripper cables 29 adapted to suspend the grab when unloading it and to open it by paying out the hoisting cables. The crane arm 1 is provided with an extension 3 supporting two suspension devices 7 each of which carries a hydraulic cylinder 12. The pistons 13 of the cylinders support a carrying device 17 on which are mounted two pairs of copper-lined clamping irons 19 each controlled by links 20, 22, lever 23, draw bar 37, and a hauling cable 26. The gripper cables 29 carry a clamping stop 30. When it is desired to weigh the load on the crane, the cable 26 is hauled by the attendant, thus bringing the clamping irons 19 against the cables 28 which slide slowly downward until the clamping stop 30 rests upon a bridging-piece 34 which has been moved into a horizontal position by the hauling movement of the cable 26. The operation results in the whole load being imposed upon the gripper cables 29 and through the clamping stop 30 to the hydraulic cylinders 12. The attendant admits pressure fluid to the cylinders and' reads off the weight on one or more pressure gauges. The hydraulic cylinder is shown in Fig. 3, and comprises an inlet 45 for the pressure fluid and a leather packing 41 which is bolted to the piston 13, and is clamped between the cylinder 12 and cover 43. When the piston has risen to a certain height a bent lever 54 is actuated by a stop 56 on the cylinder so as to open a valve 50 and allow the superfluous pressure fluid to escape. The top of the piston 13 is hollowed to receive a coneshaped pivot 15 on the carrying device.

Abstract: 710,110. Condensers. DUBILIER CONDENSER CO. (1925), Ltd. July 29, 1952, (July 31, 1951.] No. 18107/51. Class 37. An electrical capacitor is manufactured by inserting a capacitor unit into a tubular or potshaped moistureproof container, inserting an insulating closure washer which is spaced from an open end or side of the container, inserting into the space between the washer and the container end or side a mass of thermosetting polymerizable material, and baking it in situ until it has hardened by polymerization to an insulating plug adhering to the container. In Fig. i a rolled or stacked capacitor unit A (which may be of the kind described in Specification 611,900), is inserted in a container B so that one end of the unit is spaced from the open end of the container and an insulating (e.g. mica) closure washer C encircling the terminal lead D is pressed into the container after which a thermosetting polymerizable resinous material (which may be a polymerized or condensation 'ethoxylene resin or a polyarylethylene resin) is introduced, either molten or in solution into the recess E and cured in situ at e.g. 100-120‹C. for 12 to 24 hours to form a hermetically sealed plug. The other end of the container is then sealed by inserting an insulating washer G and a metal washer H connected to the terminal lead I and to a projecting tab K of the capacitance unit after which the whole is impregnated and the container is closed by solder J. The terminal lead D may be crimped to grip the resinous plug. In a modification (Fig. 2) the closure washer C is located within the container and a tubular metallic eyelet is inserted there-through after which the resinous plug F is introduced and cured in situ at 150‹C. for a shorter period. The capacitance unit A is then inserted in the container with its terminal lead D passing through the eyelet, and the open end is closed by soldering as above. The capacitance unit may be impregnated through the eyelet, which is finally closed by soldering to the terminal lead D at M. In further modifications Figs. 3, 4 (not shown) a rectangular container for rolled or stacked capacitor units is similarly closed by a thermosetting resinous plug superimposed on an insulating plate through which the terminal leads are directly passed, impregnation being effected through a central eyelet later closed by soldering, alternatively the leads are passed through metallic eyelets carried by the insulating plate, and after impregnation through the eyelets the leads are soldered thereto so as to seal the container.
