Title: Improvements in electric lampholder adaptors and the like
IPC: H01R33/94
Filed: 1924-04-09
Abstract: 221,910. Collie, J. H. April 9, 1924. Holders; caps.-In electric lamp-holder adapters &c. the conductors pass through inclined wedgeshaped grooves in opposite sides of the partition which separates the terminals, as shown in Fig. 2, such that they grip the conductors more tightly as the pull on the conductors increases. The contact members, each of which may be made of one piece secured against rotation, as shown in Fig. 3, by means of a steady pin or the like, are inclined at their contact faces so that when the adapter is inserted in a lamp-holder the spring plungers of the holder are deflected sideways and are thereby caused to make good contact with their housings. Lamp caps may be made with similarly inclined surfaces for deflecting the contact pins.

Title: Improvements in copolymer articles
Inventor: LAST ANTHONY GRAHAM MARSHALL
IPC: B29C44/50
Filed: 1965-04-30
Abstract: A film or board of foamed copolymer is obtained by copolymerizing a mixture of styrene and maleic anhydride while forcing the mixture forward, adding a blowing agent to the initial or polymerizing mixture or to the copolymer formed and extruding through a die.  The mixture which is copolymerized may contain at least one other monomer in an amount from 0.1-35% by weight. Examples of the latter are straight chain olefins having 3-36 carbon atoms, e.g. propylene, n-octene and n-octadecene; aliphatic vinyl ethers having 6-18 carbon atoms, e.g. cetyl vinyl ether.  Alternatively a "rubbery" polymer or copolymer of low molecular weight may be added in an amount from 0.1-25% by weight, e.g. polyisobutylene, atactic polypropylene, and copolymers from butadiene and styrene, isoprene, methyl methacrylate or acrylonitrile.  The copolymerization may be catalysed by a peroxide or hydroperoxide with an accelerator, an azo compound or a soluble redox system.  At least part of one of the monomers may be heated with a catalyst until homopolymerization has started and then added to the other components of the mixture.  The blowing agent may be a gas, e.g. air, carbon dioxide or nitrogen or a low boiling liquid which is not a solvent for the copolymer e.g. pentane, acetone, ethylene dichloride, methyl ethyl ketone or a fluorohydrocarbon or a solid or mixture of solids which on heating produce a gas, e.g. malonic acid or sodium carbonate/citric acid mixture.  A nucleating agent e.g. finely divided metals, may be used with a gaseous blowing agent.  Fillers, e.g. mica, may be added in an amount up to 30% of the total weight of the film.  The films or boards have at least 20% of their cells open to the surface.  An apparatus for carrying out the process consists of a screw extruder into which styrene, nucleating agent, catalyst and filler are fed through one hopper and molten maleic anhydride through another hopper.  The polymerization takes place in the second part of the extruder which is cooled.  Compressed air is injected into the melt which is extruded through a slit die as a foamed sheet which is carried on a conveyer belt and cooled by jets of air.  The cooled sheet is slit into three thinner sheets by knives and the thinner sheets are then compressed between rollers.  Alternatively, the melt may be extruded through an annular die of a twin screw extruder.  The extrudate passes over a hemispherical mandrel coated with polytetrafluoroethylene, air is supplied to the interior of the tubular film to inflate it and the foamed film is cooled.  The foamed, inflated film is collapsed between rollers and slit through its thickness.  The slit film is compressed in both cases by subjecting it to a pressure of from 10 p.s.i.-100,000 p.s.i.

Filed: 1958-06-12
Abstract: 875,389. Making bearings. SCHAEFFLER, W., and SCHAEFFLER, G. June 12, 1958 [June 14, 1957], No. 18887/58. Class 83 (2). A method of arranging balls, rollers or needles in or on cages, races or temporary holders in the assembly of a bearing comprises drawing by air suction the balls &c. against holes in the required positions and maintaining the suction while the balls &c. are engaged by the races &c. In Fig. 2, a cage 8 is located over the suction nozzle 30 and the windows 9 aligned with the suction holes 12, Fig. 3, in the - nozzle. The rollers 10 are thus drawn into the windows and retained by the outer race 11. If the windows are wider than the rollers, the bearing is removed from the nozzle on to an inner race or a pasteboard sleeve to prevent inward escape of the rollers. Instead of providing holes in the suction nozzle, suction may be applied direct to the ball-cage 14, Fig. 4, which is mounted on the end of the nozzle. In Fig. 5, air is drawn from the open end of the nozzle, outwardly through the windows 24 of the roller cage 22 and between the axial fingers 28 of a ring 23 to enter the pipe through openings 29 at the circumference of a plug 20. Thus the rollers 25 are drawn outwardly into the cage in which they are held by the inner race 27. If the cage does not prevent outward escape of the rollers, it is withdrawn direct into the outer race 30. The rollers of a flat or conical thrust-bearing may be assembled and the needles of a universal joint (Figs. 7 and 9, not shown). In the latter case, an end-ring with an inner lip supporting the needles is positioned on the nozzle before the needles are attracted.

Abstract: 1337821 Cutting apparatus GERBER GARMENT TECHNOLOGY Inc 4 June 1971 [3 Dec 1970] 19029/71 Heading B4B An apparatus for cutting sheet material 12, e.g. fabric material, comprises a cutter 16 movable relative to a supporting surface 20 on which the material is laid, the supporting surface comprising a bed 18 of a penetrable material on which is superimposed a layer 20 of a material which is restorable through the action of a restoring medium to heal cuts therein after having been penetrated and cut by the cutter during a cutting operation. The cutter 16 is reciprocated by a motor in a carriage 13 movable mounted on guide bars 2 supported on a main carriage 25. The supporting surface is formed from a bed of penetrable material, e.g. felt or foamed plastics secured to a base 19 and covered by a sheet of thermoplastic material 21. In order to cause the cuts in the upper sheet 21 to heal, heat is applied by a number of lamps 30, Fig. 1, mounted on the carriage 25 for movement therewith; alternatively, the lamps may be mounted on a separate carriage. In a modification the top sheet 21 is replaced by a sheet of material that is readily soluble by a suitable solvent applied by nozzles (33), Fig. 5 (not shown). In a further modification, the upper sheet may be of a material that when subjected to ultrasonic wave energy, turns to a semiliquid state so that the cut areas flow together and, after the wave energy is terminated, the material re-solidifies. A second sheet may be placed over the existing upper sheet and caused to weld thereto by the application of heat or be bonded thereto by an adhesive. Instead a sheet being laid over the bed, a hardenable liquid may be applied thereto, e.g. an epoxy resin. The heat may be applied by an electric element (62), Fig. 8 (not shown), incorporated in the bed in place of the lamps. The material 12 to be cut may be held down on the bed by means of a vacuum applied to a chamber in the table of the apparatus, Fig. 9, the suction being drawn through holes 38 and blocks of air permeable material, e.g. foamed plastic; a sheet 36 of air impervious material, e.g. plastics, is placed over the material 12.
