Title: Method of sealing thermoplastic film
Inventor: GATES WILLIAM ELLIOTT FREW
IPC: B29C65/40
Filed: 1962-07-13
Abstract: 963,614. Seaming non-metallic sheet material. IMPERIAL CHEMICAL INDUSTRIES Ltd. July 1, 1963 [July 13, 1962], No. 26999/62. Heading B5K. At least two layers of thermoplastic film 7 are sealed together by applying to the line or area of the seal to be made, on one or both outer surfaces of the film assemblage, a bead or ribbon 1 of molten polymeric material on an inert carrier medium 4, said molten polymeric material being at such a temperature that the film layers 7 will melt and fuse together; applying sufficient pressure to cause the seal to be made; and causing or allowing the sealed portions of the film 7 to cool to a temperature below the softening point of the thermoplastic film. In one embodiment, Fig. 1, for forming a lap seal, the molten ribbon 1 is fed from a slot die 2 secured to a screw extruder 3 on to a carrier tape 4 supplied from a reel 5. The tape 4 and ribbon 1 pass over supporting rollers 6 and the film 7 is laid on top. The assembly passes over rollers 8 and between a pair of rollers 9 to form the seal. The sealed film 10 is then cooled either by cooled nip rolls or an air blast and then the tape 4 and ribbon 1 may be stripped from the film 10. In an alternative embodiment, Fig. 2, for forming a cap seal, i.e. seals in which the assembled edges are bound together by the ribbon, the tape 4 and the ribbon 1 are folded to V-shape by a channel guide 8. The edges of the film 7 are introduced into the V-shaped channel and passed between nip rolls 9 to press the folded tape 4 and molten ribbon 1 against the outer surfaces of the film assemblage. The sealed film is then cooled, stripped and trimmed as required. Examples of film which may be sealed by this process specified are polythene, polypropylene, polyvinyl chloride, polycarbonates, cellulose acetate or copolymers thereof. The molten bead or ribbon may be made from the same material as the films to be sealed or it may be made from another polymer which is preferably of higher melting point and not compatible with the film to be sealed. Specified examples are polythene, polypropylene, nylon and polyethylene terephthalate. The tape 4 may be made of paper, polyethylene terephthalate film or aluminium foil and must be chosen so as not to melt or disintegrate at or below the temperature of the molten bead or ribbon.
Patent GB-270377-A (GB)
Abstract: 270,377. Wall, G., Trelford, W., Cartwright, R. P., Dunton, A. R., and Metropolitan-Vickers Electrical Co., Ltd. Feb. 2, 1926. Moulding gums and resins. -Motor meters, particularly of the mercury type described in Specifications 245,536 and 245,707, [both in Class 37, Electricity, Measuring &c.], have substantially the whole of one or more permanent magnets 13 moulded into a body of insulating material, the setting or curing temperatures of which are such as will not injuriously affect permanent magnets. The parts are assembled within a mould and the moulding- material is poured or forced in and cured to form a solid body. A slot 29 and recess 30 are formed to accommodate the disc and spindle; recesses for the electrodes and a dowel-hole for positioning the unit on the cover of the mercury trough are also formed. The maximum temperature required for curing the moulding material should be not more than 100‹ C. in order not to affect the magnets injuriously. The material may be a phenolic condensation product which may be poured as a thick liquid into the mould, with or without a small amount of filler; or it may be a cured or partly cured phenolic condensation product dissolved in acetone alcohol, methylated spirit, etc.; or it may be a thiourea condensation product or a natural or synthetic resin capable of being hardened and cured below 100‹ C. The preferred material is a mixture of " Haefely C vaxnish," glycerine, water, and hydrochloric acid. with wood flour as filler. The material is poured down the sides of the mould when an open mould is used, or forced into an enclosed mould by means of a ram, pump, or air pressure from the bottom of the mould. The filled mould is immersed in an oil bath at between 90‹ and 100‹ C., which causes the material to set. It is removed at about 60‹ C. and subsequently cured at a moderate temperature.

Title: Improved pressure die-casting machine
IPC: B29C45/67
Filed: 1945-10-16
Abstract: 605,203. Casting-machines. PLASCO, Ltd. Oct. 16, 1945, No. 27111. Convention date, Jan. 26. [Class 83 (i)] [Also in Group V] In a pressure casting-machine having a pair of dies each movable towards and from the other, air actuating means for closing the dies and holding them in closed position is controlled by a common valve. This may be done by using low and then high pressure air. Casting composite articles ;moulds ; extracting castings.-In a machine for casting fastener elements of a sliding-clasp fastener on to a tape 85, this is held by grippers 86, Figs. 2 and 3, which are closed by plungers 110 forced apart by high pressure air controlled by a valve 33 which is rotated by a power-driven belt 31, but can be rotated by a hand wheel 32. Continued rotation of the valve 33 then admits low pressure air to adjustable cylinders 70 behind spring-returned pistons 71 to close two water-cooled dies 23 on the tape, the shock being taken by rings 73. Then high pressure air is admitted to the cylinders 70 to hold the dies firmly closed. Each die, in closing, engages a lever 96 to move an adjustable valve 87 to closed position and, if either die does not make a full stroke, the corresponding valve 87 does not close. The valve 33 then admits air pressure to the valves 87 and, if either is open, the air actuates a switch to stop the machine. A cam 139 on the spindle 38 of the valve 33 then opens a valve 140, Fig. la, if the machine has not been thus stopped, to admit air pressure to the gooseneck and thus force casting-material through a nozzle 83, Fig. 2, into the die. Continued rotation of the valve 33 then exhausts the pressure in the gooseneck, thus allowing the casting material to flow back, in the cylinders 70, thus allowing springs 77 to open the dies 23, in the space 111, Fig. 3, thus allowing a spring 115 to open the grippers 86, and in a space in a cylinder 117 above a piston 118, Fig. 2, thus allowing a spring 119 to move up the piston 118 and the whole gripping device 101, carried thereby, to the position shown. Finally, the valve 33 admits air pressure to the space 111 and cylinder 117, thus causing the grippers 83 to close on the tape 85 and feed it down through a distance regulated by a detachable spacing block 123. The spindle 38 drives, through worm gearing 39, 40, a chain 43, Fig. la, so that it advances one link for each cycle of operations. Trip plates 142 are attached to some links, each of these acting on a lever 143 to stop the valve 140 from being opened by the cam 139 so that no casting is made during the corresponding cycle of operations. Each cylinder 70 is adjustably mounted in a slide 69 which can be moved outwardly from its normal position shown by an eccentric 133 and handle 132 and the cylinder 117 is pivoted at 116 and secured by lugs 127 and bolts 129 so that the tape-feeding mechanism can be swung out of the way when required. The die-cavities may be shaped as 81, Fig. 5, to produce undercut elements 84 and, to facilitate extraction, they may move angularly one to the other instead of in the same line.

Abstract: 1401581 Automatic control of deceleration ROBERT BOSCH GmbH 8 June 1973 [9 June 1972] 27363/73 Heading G3R [Also in Division F2] An anti wheel-locking control system for a fluidpressure operated wheel brake comprises a pulse tachogenerator 10 connected to a frequency/D.C. voltage converter 11, and a first threshold value switch 13 whose input is connected to the converter by way of a differentiator 12, a first timing circuit 14 being arranged between the threshold switch and a transistor switch 23 for supplying a solenoid 24 of a pressure reducing valve with current via a NOR gate 22 and releasing the current flow thereto after the threshold switch has responded and interrupting the current flow after a first predetermined interval has expired, even upon the failure of a reset signal. A signal from the converter 11 is also passed to a first input of an adding circuit 19 and to a vehicle velocity simulator 15 the output of which is fed to a further input of the adding circuit 19 via an inverting amplifier 17, Fig.2 (not shown), thereby giving an indication of slip. The output of circuit 19 passes to a second timing circuit by way of a further threshold valve switch which responds at a given slip value to pass a signal via NOR gate 22 to transistor 23 to relieve braking pressure. Thus transistor switch 23 is responsive to either a deceleration threshold value by means of switch 13 or a slip threshold value by means of switch 20. A cut-out circuit 26 is described which if transistor 23 malfunctions blocks current flow to solenoid 24 after a second predetermined interval so that the brake pressure cannot drop any further. A lamp 32, Fig. 4 (not shown), gives a warning of malfunction. A single timing circuit may be provided for the two threshold valve switches 13, 20. Circuits are described for simulator 15, adding circuit 19, switch 20, timing circuit 21, NOR gate 22 and cut-out circuit 26.
