Title: Improvements in or relating to shock absorbers
IPC: F16F9/26
Filed: 1940-03-13
Abstract: 541,201. Shock absorbers. JOHNSON, E. W., and VANDERVELL PRODUCTS, Ltd. March 13, 1940, No. 11047/41. Divided out of 541,179. [Class 108 (iii)] In a hydraulic shock absorber in which an arm on a rocking shaft reciprocates a piston, the operating connection includes two arms straddling the piston and having on their inner faces bosses which are embraced by bearing members located between guides on the pistons and subjected to spring pressure to take up wear. In the arrangement shown in Figs. 1, 2 and 5, pistons 30, 31 operate in cylinders 28, 29 mounted on a housing 16 containing fluid to make up deficiencies in the cylinders. The restriction between the cylinders is provided between a fixed metering rod 42 and a sleeve 32 which extends through the pistons and is sealed thereto by the flared end 33 and by packing 34, this packing being pressed home by a spring 36 serving also to press the two pistons towards one another to engage the bearing members. The two arms 57, 58 on the rocking shaft 21 are fixed to a barrel shaped sleeve 56 splined to the shaft. Each arm carries on its inside a boss 59 adapted to receive a split bearing 62, 63 having flat sides to bear against facing guide plates 61 on the pistons. A spring 65 retains the split bearing parts together during assembly. End movement of the rocking shaft 21 is prevented by a crossbar 66 mounted between the arms 57, 58 and engaging pins 67 on the container, the cover 17 of which is secured by a screw 68 to the crossbar. In the modification shown in Fig. 6, the two pistons are rigidly connected and wear between the lug 82 on the ends of the rocking arms and the guides 83 on the pistons is taken up by tapered 'bearing strips 85 which are pressed upwards by a spring 86.

Abstract: 1535716 Sealing strip DRAFTEX DEVELOPMENT AG 15 Oct 1975 [20 Nov 1974] 11074/78 Divided out of 1535715 Heading EIJ A channel section sealing strip comprises a metal carrier member 18 completely embedded in flexible material; all the flexible material on the inside surface of the carrier is relatively soft 112 and defines gripping ribs 114, 116, the flexible material 110 on the outside of the carrier is relatively hard; a beading 16 of the softer flexible material is provided. The relatively harder flexible material may be plastics e.g. PVC and the softer material may be rubber. The strip may be formed by first extruding soft material on to the carrier blank and forming the beading, then extruding the harder material and finally bending the strip into channel form.

Abstract: 674,843. Feeding sheets. BACKHOUSE, H. T. April 22, 1949 [April 22, 1948], No. 11098/48. Drawings to Specification. Class 100 (i). Sheets are separated from a pile by means of a suction gripper moved to engage and lift the top sheet of the pile, the movements of the gripper being effected or controlled by a valvecontrolled suction-operated piston-and-cylinder or equivalent bellows or diaphragm arrangement, and the cylinder being oscillated to forward or assist in forwarding the separated sheets in a direction transverse to the height of the pile; the cylinder is continuously connected to a source of suction the application of which is controlled by a pivoted flap valve sealing a port in the cylinder wall and co-operating, during the movement of the cylinder, with a stop which opens the valve to atmosphere to destroy the suction at the appropriate time in the movement of the cylinder. The apparatus is identical with that described in Specifications 674,842 and 674,844.

Filed: 1941-09-02
Abstract: 551,719. Fuzible cut-outs. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 2, 1941, No. 11204. Convention date, Sept. 19, 1940. [Class 38 (i)] A current limiting fuse comprises a block 14 of resistance material such as carbon, carborundum, &c., arranged in parallel with arc-establishing means such as a fuse wire 10, in a channel of restricted crosssection, and a fuse wire 18 in series with the combination. The wire 10 is laid in a screw thread on a carrier 8 which screws loosely into the tube 2 made of material such as fibre or synthetic resin that evolves an arc-extinguishing gas. The wire is sealed in the base of the screw thread by a viscous paint applied before the parts are screwed together, the paint containing a gas-cooling material in a cellulose acetate or ethyl cellulose solution. A multiplethread screw allows several fuse wires to be mounted in parallel if required. The fuse 18 is looped through one end of a toroidal spring 26 that draws the wire back through a filling 32 of powder which may be a gas-evolving material such as boric acid, gypsum &c. In a modification a metal partition is inserted between the resistor 14 and the wire 18, a block of gas evolving material replaces the powder 32 and a tapered helical spring lies in a cavity outside the end of the cap 6 instead of the spring 26. A disc carried on the external spring acts as an indicator.

Abstract: 527,725. Surface hardening metal articles. NATIONAL CYLINDER GAS CO. April 13, 1939, No. 11274. Convention date, April 16, 1938. [Class 72] In the surface hardening of a metal article 10 by progressively advancing a sheet-like flame produced by an elongated nozzle 30 of an oxyacetlylene torch 25 to heat successive portions of the surface to the critical temperature and then chilling such portions immediately by a stream of water directed thereon from a nozzle 32 fitted into a supply pipe the heating and melting of the boundary edges of the surface is prevented by the application of a coating of heat resisting material 20 to the marginal surfaces at an angle to the surface treated. The heat resistant material may comprise an alkaline metal silicate used alone or as a binder, plumbago or other fire-resisting substances such as fireclay, alundum cement, silicon carbide, magnesite, asbestos, silica and porcelain powders such as sillimanite, made into a paste solution or suspension with binders such as sodium or sodium aluminium silicate, dextrine, glue, glucose or isinglass.

Abstract: 1,136,843. Casting metals. COMPAGNIE POUR L'ETUDE ET LA REALISATION DE COMBUSTIBLES ATOMIQUES. 15 March, 1966 [15 March, 1965], No. 11323/66. Heading B3F. In a process for producing a plurality of metal castings simultaneously in moulds 22 supplied with molten metal from a distributer 10 positioned above the moulds, the metal is supplied to the moulds 22 through respective orifices 24 and at least one auxiliary orifice 30 into an auxiliary mould 28, the auxiliary orifice 30 being at a lower level than the other mould orifices 24. When casting molten metal discharged from the crucible 11 passes into the distributer and through the respective orifices into the moulds. The orifice 30 of the auxiliary mould may be smaller than the orifices 24 of the other moulds or the capacity of the auxiliary mould may be greater than the other respective moulds so that the mould 28 fills more slowly and also any metal remaining in the distributer when the moulds 22 have been filled, passes due to the lower level of the auxiliary orifice 30 into the auxiliary mould. The metal cast in the auxiliary mould may be subsequently remelted. The process may be carried out in a vacuum.

Abstract: 638,349. Grinding twist drills. GANZ, J. April 12, 1946, No. 11360. Convention date, April 13, 1945. [Class 60] An appliance for grinding twist drills is characterized in that the support for the drill to be ground comprises a bar of circular cross-section including a longitudinal groove of angular form with plane faces to take the drill to be ground and positioned obliquely in relation to the grinding surface to grind the point of the drill to a required cone angle, said bar being so mounted that a clearance is ground behind the cutting edge by a swinging movement of the bar. A drill 13 is held in a longitudinal angular groove 5 in a cylindrical bar 3 by a clamping spring 15, Fig. 3, tensioned by a nut 16, and is adjustable therealong by a step member 18, an inclined positioning lip 10 on the bar 3 bearing against a cutting edge of the drill.
