Patent GB-1094480-A (GB)
Title: Laminated sheet material
Inventor: RASMUSSEN OLE-BENDT
IPC: B29C65/48
Filed: 1964-03-03
Abstract: 1,094,480. Laminates. METAL CONTAINERS Ltd. March 2, 1965 [March 3, 1964], No. 8967/64. Heading B5N. To improve the tear resistance of laminates of films of polythene, crystalline polypropylene, polyamides, polyvinylidene chloride and polyethylene terephthalate undirectionally oriented films are secured together, with their directions of orientation differing in adjacent plies, by a combination of spot welding and a viscous lubricating material applied in areas not spot welded The lubricating material may comprise 60-80% lubricating oil, 5-15% polythene (M.W. 5000-15,000) and 10-20% polyisobutylene (M.W. 15,000) and may be applied in stripes, 2-20 times the widths of the welds, by printing apparatus, the strips preferably being at an angle bisecting that formed by the directions of orientation in adjacent films. Spot welding may be affected by the application of hot xylene vapour as described in Specification 1,084,721 to the areas between the stripes. The invention may be applied to three-ply laminates of high density polythene the middle layer of which is oriented longitudinally, the outer layers being oriented at 60 degrees to the right and left respectively.

Title: Glass feeder plunger-operating mechanism
IPC: H01R33/08
Filed: 1952-04-08
Abstract: 693,276. Glass manufacture. CORNING GLASS WORKS. April 8. 1952 [May 23, 1951], No.8993/52. Class 56. In a reciprocating plunger glass feeding mechanism for use with a molten glass container having a bottom outlet, the plunger is supported by the movable element of a fluidoperated unit, the fluid supply to which is controlled by a cam-actuated tracer valve, and a linkage is provided between the element and the valve which operates the valve to restrict the movement of the element once it has commenced. In the form shown, a feeder plunger 10, which controls the formation of gobs from an outlet 13 of a bowl 15, is attached by an arm 11 to a cylinder 16 which is raised or lowered on a rod 20 provided with a piston 22 by the admission to either side of the piston of an operating fluid supplied via passages 23 and 24. These passages extend to the outlet ports of a tracer valve 30, the movement of the slider of which directs fluid under pressure from a pump 31 to one side or other of the piston. The slider is actuated against a return spring by a lever 47 attached to a rack 51 engaged by a pinion 52 carried on a bar 53 which is raised or lowered by a lever 67 actuated by a follower 66 bearing on a cam 60. At its other side, pinion 52 engages a second rack 54 which is connected by an adjustable lever 55 to a rod 59 secured to cylinder 16 by an arm 50. The arrangement allows the plunger 10 to follow exactly the movement determined by the cam contour. For example, when follower 66 is raised by the cam 60, the arm 53 is lowered and, since rack 54 is initially stationary, the pinion 52 revolves and lowers rack 51 and lever 47, depressing the slider of valve 30 to admit fluid under pressure to the upper side of piston' 22, so raising cylinder 16 and the plunger 10. Bar 59 is also raised and acts through lever 55 to lower rack 54 and revolve pinion 52 in the reverse direction so that the valve slider is returned to its normal position almost immediately the movement due to the cam has stopped.

Abstract: 417,171. Washing-machines. HELLMICH, E., 26, Brucknerstrasse, Botnang, Stuttgart, Germany. March 22, 1934, No. 9020. [Class 138 (ii).] The drive is transmitted from the motordriven shaft 1, Fig. 5, to the gear-wheel 19 on the washing receptacle shaft 20 through a wormwheel 3 fast on a shaft 4 and a spring 5 anchored at one end to the wormwheel and at the other to a projection 6<1> on a sleeve 6 which operatively engages a hollow shaft 9. A gearwheel 8 is formed on one end of the shaft 9 and engages gear-wheels 16, 17, Fig. 1, carried by shafts 14, 13 parallel to the shaft 4 and carried by a plate 11 which is rocked about the shaft 4 to bring the gear-wheel 17 and another gearwheel 18 which is driven by the gear-wheel 16 alternately into engagement with the gear-wheel 19. The rocking of the plate 11 is effected by the engagement of cams 44, 45 with arms 29, 30 yieldingly connected to the plate, the cams being carried on the opposite faces of a disc 46 which is slowly rotated in a constant direction from the motor shaft 1 through a double Geneva mechanism. The plate 11 may be held in the inoperative position shown by the engagement of a latch 27 with an arm 23 projecting from the plate. In another form, the reversing mechanism is omitted and in order to disconnect the drive the receptacle shaft may be raised vertically or moved axially by manually-operated eccentrics or the intermediate drive shaft may be moved similarly.

Title: Improvements in or relating to plugs or closures
Inventor: GUIVER DENNIS WILLIAM
IPC: F16L55/11
Filed: 1960-03-16
Abstract: 886,630. Reactor pressure vessels. FLIGHT REFUELLING Ltd. March 16, 1960 [March 16, 1959; Feb. 17, 1960], Nos. 9036/59 and 5663/60. Drawings to Specification. Class 39(4) [Also in Group XVIII] The stack-pipe closing plug of a nuclear reactor is locked in the pipe by a series of balls which are mounted round the plug circumference so as to engage a groove in the pipe inner surface. The balls are carried in apertures in a sleeve surrounding, and slidable on, the plug, and relative displacement of the sleeve and plug causes the engagement of each ball with a cam to produce radial displacement of the balls. The plug is extracted by a tool which effects the relative displacement of the sleeve and plug and permits the radially inward movement of the balls from the plug groove to unlock the plug. A plunger sensitive to the fluid pressure difference across the plug prevents the displacement of the balls inwards from the groove and thus maintains the locking action when the pressure is greater on the inner side. In a second embodiment, the fluid pressure difference across the plug maintains the sleeve and plug relatively displaced so as to hold the balls in the locked position. In a further embodiment, release of the balls is effected by a rotation of the sleeve round the plug followed by a longitudinal displacement.

Title: Improvements in or relating to generation of nuclear power
Inventor: STRATFORD WILLIAM MALCOLM
IPC: G21D3/08
Filed: 1953-04-08
Abstract: 749,064. Nuclear reactors. TEXACO DEVELOPMENT CORPORATION. April 8, 1953, No. 9521/53. Class 39 (4). [Also in Group XXVI] In a nuclear reactor the fissionable material is maintained in a fluidized phase or is used to fluidize a moderator. The reactor 11 contains particles of compounds comprising U<SP>235</SP>, U<SP>238</SP> and/or Pu, fluidized by a gas pumped at 34 through 37 and extracted at 18 through a cyclone separator, fines being returned at 21 from this separator and at 29 from an ultrasonic or electrostatic, separator 28. The fluidizing medium may be air, hydrogen, deuterium or helium. A coolant is preheated at 23, and then heated in a coil 38 to drive a turbine 42. Alternatively or in addition to this system, a coolant in tubes 38a in the reactor walls passes through a heat exchanger 40. Na, K, Bi, Pb and Sn in their molten phases, water and/or heavy water, diphenyl, He, and H are described as suitable coolants. Particles of graphite or beryllium may be included in the reactor if the fluidizing medium is not of itself sufficient as a moderator, and particles of Zr, Mg, or A1 may be included to improve the heat transfer. In response to temperature rises at 47, 48, 49 or increase in radiation at 51, 51, rods 14, 16 of Cd or B are advanced into the reactor; or the rate of flow or the pressure of the fluidizing medium is increased, or the proportion of hydrogen to deuterium in this medium is increased, thus controlling the nuclear reaction. A part of the fluidizer stream is processed at 32 to extract radio-active isotopes. The vertical rods 16 retard the reaction rapidly if the flow of fluidizer ceases and the fissionable particles fall. Uranium hexafluoride gas may be used to fluidize moderator particles of graphite or beryllium oxide. The coolant may also be used as the fluidizer, Fig. 2 (not shown). The reacting particles may be fluidized mechanically, Fig. 4, by helically pitched blades 164, with the aid of a fluidizing medium admitted at 185 and removed through filters 188, the reactor and blades 164 being cooled by a coolant admitted at 153, 156, 159, 169. In heat exchangers 176, 194, heat is extracted from the coolant and from the fluidizer.
