Title: Improvements in or relating to parachutist's equipment
Inventor: PRAGNELL JOHN JAMES MUIR
IPC: B64D17/32
Filed: 1959-04-22
Abstract: 880,499. Parachute equipment for aircraft ejection seats. IRVING AIR CHUTE OF GREAT BRITAIN Ltd. April 21, 1960 [April 22, 1959], No. 13733/59. Class 4. Parachutist's equipment includes an ejector seat 1 and a parachute pack associated with a barometrically controlled release unit which during an ejection bale out is adapted to be armed pursuant to the parachutist becoming separated from his seat by means of an arming cable 13 extending from the seat to the barometric unit, characterised in that means are provided for bringing about the automatic disconnection of the arming cable from the seat pursuant to the user leaving the seat without making an ejection bale-out whilst enabling the connection to be maintained if the user makes an ejection bale-out. A cone 11 is mounted on a notched plate 7, attached to seat 1 and supporting a cone 6 extending from plate 5, which is attached to the parachutist's harness by a strap 3. Cones 6 and 11 each have a transverse opening through which one leg of spring pins 8 and 14 respectively can pass. Cable 13 is anchored to seat 1 by cone 6 and pin 14, the latter having a ring-like head which is positioned on cone 6 before pin 8 is inserted. The pin 8 is attached to a static line 9, fastened to aircraft structure 2 and incorporating a spring 10 so that pin 8 has a limited freedom of movement. In an ejection bale-out, line 9 will withdraw pin 8 from cone 6 allowing pin 14 to slide from this cone. In this position, pin 14 still engages cone 11 so that cable 13 remains attached to the seat and will arm the release unit when the parachutist separates from his seat. In a manual bale-out, the parachutist releases seat safety harness 4 and rises, so that strap 3 draws plate 5 and cone 6 away from plate 7, thereby withdrawing pin 14 from cone 11 and releasing arming cable 13. As soon as line 9 becomes taut, pin 8 withdraws from cone 6 and the parachutist will be free to bale out and release his parachute manually.

Abstract: 900,169. Packaging machines. PNEUMATIC SCALE CORPORATION Ltd. April 20, 1960, No. 13819/60. Class 94(1). A machine for closing by heat sealing the open bases of tubular thermoplastic containers comprises means for clamping a row of the containers adjacent the base edges, for exposing the edges to radiant heat and for pressing the heat activated edges into coalescing contact during setting. Containers such as filled collapsible tubes 290 are placed in holders 278 on a slide 280 which is then moved manually below the closing means. Opposed jaws 150, 152 having water cooled tubes 270, 272 beneath them are moved to clamp the tube ends, by slides 156, 176 and a link 204 on a shaft 198 operated by a hand lever 202. The jaws are held closed by a ball and notch catch 222, 224 and the carriage 154 on which they are mounted is raised by a pneumatic motor 260, Fig. 1, so that the exposed edges of the tubes are brought adjacent to radiant heating means 106, 110. After a timed delay, jaws 60, 72, operated by slides 42, 62, a link 120 and a pneumatic motor 142, move towards each other to press the heated material, the heaters being raised clear by members 98, 100 on the slide 62. The jaws 60, 72 have associated cooling tubes 76, 78. During sealing, the slide 280 is withdrawn to be re-charged and when the sealed containers are released by the jaws 60, 72, they fall through an aperture 288 on to a conveyer, &c., not shown. The machine is adjustable for various tube lengths, the whole of the sealing mechanism being vertically slidable relative to the slide 280 in guides 338,340.

Title: Improvements in or relating to welded thin sheet metal articles and method for making the same
IPC: B23K20/00
Filed: 1960-04-25
Abstract: 922,700. Making cars ; welding by pressure. CONTINENTAL OIL CO. Inc. April 25, 1960 [Feb. 29, 1960], No. 14447/60. Classes 83 (2) and 83 (4). In an article made from thin sheet metal and having a welded joint formed by a diagonal weld interface, the weld is formed by forge welding without the formation of molten metal, the metal of the joint is generally metallurgically homogeneous and free from weld nuggets and only welded edge portions of the metal sheet are heat affected. The article may be formed of two separate strips or a thin metal strip, e.g. 0.004-0.011 inch thick, may be formed into an open tube B, Fig. 1, having opposed edges 5, 6. The open tube is fed at e.g. 300 ft. per min. between forming rolls 7, 8 where the edges are caused to converge and overlap and the edges are heated by current of high frequency, e.g. 450 kc. per sec. or as low as 10 kc. per sec., supplied through contacts 13, 14 in contact with the edges which latter are held spaced ahead of the rolls 7, 8 by a wheel W. A magnetic core comprising magnetic rods 17 is arranged within the tubing. The edges are heated to plastic condition and are then passed between a concave surfaced roll 18 outside the tube and a convex surfaced roll 19 supported on a member 21 within the tube to forge weld the edges with a diagonal weld interface 26, Fig. 6, and to reduce the thickness of the overlapped edges to between 1 and 1.5 times the tube wall thickness. Back-up rolls 23-24 are provided diametrically opposite the rolls 18, 19. The weld does not involve molten material but only a recrystallized structure at and surrounding the weld interface. In the case of a tube joint formed from tinplated steel strip the heat affected zone extends 0.1 inch from the unaffected zones 30, Fig. 6, the zones 31 comprising partial solution of carbides in austenite, with substantially unchanged ferrite matrix, the intermediate zones 32 comprising complete solution of carbides and diffusion of carbon in austenite with the ferrite enlarged and zones 33 comprising complete solution of carbides in austenite. The weld interface is not visible as such even when greatly enlarged since ferrile crystals have grown across the interface. The tin coating 35 remains on the strip about # inch from the weld but adjacent the weld, the tin melts and is removed by the forging. The tube may be cut into short lengths to form can bodies-in this case the tube blank is decorated in advance- and the ends of the short lengths are flanged at both ends. Alternatively, individual can bodies may be welded. The strip may be of steel coated with tin, zinc, stainless steel, titanium, zirconium, aluminium, cadmium, copper, brass, nickel, chromium, lead, cobalt or manganese, of aluminium, copper, brass, nickel, nickel base alloys or aluminium base alloys and may be of the above metals enamelled. For welding aluminium strip the frequency of the current supplied to the contacts should be less than 100 kc. per sec.

Abstract: 1413937 Locking nuts MATRIX SCIENCE CORP 3 April 1974 14798/74 Heading F2H [Also in Division H2] Two electrical connector members are secured together by screwing a self-locking nut 32, captive on a sleeve 12 of one member, or toa threaded sleeve 102 of the other member. A ring 62, urged against an annular flange 22 of the sleeve 12 by an undulating spring washer 68, has protuberances 64 to engage in recesses 26 of the flange 22, and is keyed to the nut 32 by lugs 66, 67 engaging in slots 44 of the nut. A snap ring 74 in the nut provides an abutment for the spring washer 68. The nut is tightened, increasing the spring force on the ring 62, until the lugs 66, 67 are aligned with ridges 54 on the nut exterior to indicate correct locking. The protuberances may be on the flange 22 and the recesses in the ring 62 in an alternative arrangement. In a modification, Figs. 4-6, not shown, an additional ring (226) carries the recesses or protuberances instead of the flange 22, and has lugs (234) projecting axially to engage slots (222) in the flange to key the ring (226) to the flange.
