Title: Method for producing laminar articles
IPC: B29C43/18
Filed: 1974-10-17
Abstract: 1529433 Thermoplastic coatings IMPERIAL CHEMICAL INDUSTRIES Ltd 29 Sept 1975 [17 Oct 1974] 45030/74 Heading B2E [Also in Division B5] A method for coating the surface of a substrate with a thermoplastic material, by pressing the material against the substrate surface with a die heated to a temperature above the softening point of the material to fuse the material and cause it to flow and form a coating layer conforming to the shape of the die, and then cooling the layer to harden it before removing the die, wherein the substrate is infusible at least under the conditions existing during the coating operation, and the thermoplastic material initially has a cellular structure which becomes destroyed as the material fuses and flows to form the coating layer, and the cellular thermoplastic material is formed by emulsifying water in a water immiscible, polymerisable liquid to form a reverse emulsion, polymerising the said liquid while maintaining the emulsion and then removing the water. The substrate may be chipboard, blockboard, high softening or infusible plastics foam, e.g. of urea-formaldehyde resin or a stiff fibrous butt. The cellular material may be polymethylmethacrylate or a copolymer of methyl methacrylate with 2-ethyl hexyl acrylate and may be applied to the substrate in the form of a preformed sheet or block or as coarse particles e.g. chips or beads. The method may be used for forming a layer on a single substrate surface, on selected surfaces e.g. one face and all edges, or to completely encapsulate the substrate. Figs. 1, 3 and 5 show sections of open moulds used for encapsulation, each mould comprising two relatively movable discs in the form of platens 1, 2 having heating means (not shown) contacting glazing plates 3, 4. In the embodiment shown in Fig. 1, mould tools comprising two superimposed edge-defining members 5, 6 surrounded by a bolster 7 enclose an area between the dies, the core 10 being interposed between two sheets 11, 12 of cellular material and blocks 13 of the cellular material being arranged around the edges of the core and located between the edgedefining members 5, 6. In the embodiment shown in Fig. 3, a single edge-defining member 31 bounded by two bolsters 32, 33 biased against their adjacent glazing plate e.g. by spring 34 are used, the sheets 11, 12 of cellular material extending over the edge defining member. In the embodiment shown in Fig. 5 a drawer front having an integrally moulded finger grip 71 (Fig. 7) is produced, the finger grip being formed by the shape of the edge defining member 51 which is in the form of a rectangular sectioned block 51 having a rebate 52, 53 along the two edges of one face, the surfaces of the chipboard core 10 being covered by cellular sheets 54, 55 one sheet 55 extending slightly beyond the core, the other sheet extending over the edge-defining member 51 which is supported on a block 56 of cellular material located on the deeper of the two rebates 53.

Abstract: 1,273,495. Portable containers. PORTERLANCASTRIAN Ltd. 22 Sept., 1970, No. 45038/70. Heading B8D. [Also in Divisions F1 and F2] A container for storing and dispensing carbonated beverages, e.g. beer, comprises a body shell consisting of interconnected cupshaped parts 11 and 12, a flexible lining bag 13 secured at its mouth to a beer inlet/outlet fitting 14 fastened to an aperture in the domed end wall of the lower shell part 11, and radiallyspaced interconnected inlet/outlet parts 21 and 24 in the domed end wall of the shell part 12 for charging and discharging compressed air between the shell and the bag. In the filling of the container, the bag is entered into the shell in the collapsed condition and the shell interior is filled with compressed air. Beer is fed through the fitting 14 into the bag and erects the bag against the air pressure which is progressively relieved through the ports 21 and 24. The provision of two air inlet/outlet ports permits the release of air from shell during filling from one of the ports in the event of the other port being marked off by the bag on the inflow of the beer. After filling, compressed air is again fed between the shell and bag to facilitate dispensing and to maintain the carbon dioxide in the beer in solution. The ports 21 and 24 are connected to a pipe 22 having a self-sealing coupling 26 by fittings 23 and 25 respectively, the latter incorporating a pressure relief valve. The beer inlet/ outlet fitting 14 comprises a tubular spigot 29a sealingly secured to a support plate 14c which is bolted to the lower shell part. The external end of the spigot terminates in a self-sealing coupling 29. A liquid level indicator in the form of a reflecting tape is provided on the shell inner surface and is visible through one or more inspection ports. The container may be provided with a jacketed cooling system.

Title: Improvements in or relating to Perforating Appliances.
Inventor: RUEDGISCH EDGAR VON
IPC: B26D5/22
Filed: 1967-10-09
Abstract: 1,179,130. Perforating-appliances. E. V. RUDGISCH. 9 Oct., 1967 [8 Oct., 1966], No. 46062/67. Heading B4B. A pneumatically-operable hand controllable portable appliance for perforating stencils of paper or plastics foil comprises a perforating tool 51 fastened to a piston 56 movable in a cylinder 16 by compressed air supplied by a line 18 in which is located a valve 24, a grooved plate 58 being connected to one end of a lever 62 pivotable about a bolt 70 against the action of a spring 76, the other end of the lever 62 being connected by a wire 78 to a microswitch 22 of the valve 24. The bolt is movable in a slot 72 in the casing of the appliance. The swivel movement of the lever 62 is limited by a stop 82 adjustable in a casing slot 80 by a screw 86. The lever 62 is connected to a spring-influenced lever 64 to which is connected a lever 66 pivotable about a fixed fulcrum 68; the free arm of the lever 66 projecting into the cylinder 16. The piston 56 comprises a plate 30 which sits on a tappet 28 movable in a bushing 34 against the action of a spring 40. A punch 42 is connected to the tappet 28 by means of a screw-threaded bolt 44 and has circumferential slots 46 into which a key can be inserted for adjusting the punch and into one of which projects a bolt 48. The punch has the tool 51 removably secured thereto and a bore 53 in the tool communicates with a transverse bore 54 for removing punchings. On the plate 30 sits the upper portion of the piston 56 surrounded by an annular groove 57 to which compressed air can be supplied. In operation, during displacement of the appliance, the plate 58 remains adhered to the material of the stencil 60. This causes the lever 62 to turn counterclockwise about the bolt 70 and the wire 78 to close the microswitch 22 to open the valve 24 so that compressed air acts on the upper portion of the piston 56 to drive the tappet 28 and the tool 51 downwards. The working stroke is completed when an elastic ring 32 impinges on the top of the bushing 34. During the working stroke, the upper portion of the piston 56 impinges on the free end of the lever 66 and turns it counterclockwise about its fulcrum 68. Thereupon, the lever 64 is lifted and lifts the lever 62 with it. This raises the plate 58 which then swivels clockwise, under the action of spring 76, to its starting position. At the same time, the tool 51 has punched a hole. The spring 40 returns the piston 56 and tool 51 to their original positions. Also, the lever 66 pushes the lever 64 downwards which in turn pushes the lever 62 and plate 58 downwards so that the plate again adheres to the material of the stencil 60.

Title: Pressure hose and method of making it
IPC: B29D23/00
Filed: 1967-10-16
Abstract: 1,205,450. Method of making a pressure hose. DUNLOP CO. Ltd. 16 Oct., 1967 [17 Oct., 1966], No. 47008/67. Heading F2P. A method of making pressure hose comprises the steps of forming a body tube of rubber, placing a selected length of the tube on a straight mandrel which is a neat fitting within the tube, tightly encasing the mandrel-mounted piece of tube with an open-mesh braid, openmesh meaning that the exposed area of rubber should be at least 50% of the total outside cylindrical surface of the body tube, externally coating the braided piece of tube with a liquid rubber adhesive medium, encasing the adhesive coated piece of braided tube within a cover sleeve, and finally curing the sleeved piece of tube. The cover sleeve, which is circumferentially contractile, or expansible, is knitted with a mesh close enough to leave substantially none of the adhesive-coated surface of the braided tube uncovered by the sleeve. The term rubber includes natural and synthetic rubbers and plastics or other materials commonly used as equivalents of ordinary rubber. The curing may be carried out with the straight mandrel still inside the tube or, the straight mandrel may be replaced by one which is not straight. To form a straight circumferentially ribbed hose the body tube, of greater length than finally required, is, e.g., tightly wound, while still on the mandrel, with a wire with a helical pitch, e.g. twice as much as the finished ribbing, the tube then being compressed axially to its required length and cured while still on the mandrel. The helical wire may be left on the hose for reinforcement. The ribs may be formed by removing the mandrel and supplying the interior of the tube, having the wire wound thereon, with air under pressure. The helical wire may be replaced by a number of axially-spaced rings, and the rings, or wire, may be made of cotton or rayon, and be applied to the tube before the covering sleeve. Although the latter is preferably formed of closemesh fabric, it may be of rubber or other suitable material. The helices of the braid may be multi-start.

Title: Tension levelling of strip
IPC: B21D1/05
Filed: 1973-10-09
Abstract: 1447781 Tension levelling strip; rolling WEAN UNITED Inc 9 Oct 1973 [6 Nov 1972] 47127/73 Heading B3E and B3M Flat metallic strip 10 is produced by subjecting the strip to a substantial total tension below its yield point, passing the tensioned strip around a series of strip flexing rolls which subject the strip to reverse flexing sufficient to impart a small amount of elongation to the strip, varying the unit tension transversely of the strip to vary the transverse unit tension of the strip portion subjected to the flexing operation, determining the transverse flatness profile of the strip, and reducing the non-flatness in the strip by changing at least one of the total tension, flexing or unit tension operations. The strip flexing operation may include a simultaneous rolling and flexing of the strip. The strip 10 passes through strip tension bridle units 12, 14 each having driven rolls 16, 18, 20, 22 and a pinch roll 24 for subjecting the strip to total tension up to the yield point of the strip. A housing 32 includes two sets 28, 30 of rolls for flexing or rolling and flexing the strip. Roll set 28 includes an adjustable back up roll 34 which engages a roll 36 nested between roll 34 and rolls 38, 40. A piston cylinder assembly 46 is used for vertically positioning a bearing chock assembly 42. Thus, the penetration of roll 36 into the space between rolls 38, 40 can be varied from a rolling condition where the strip is both flexed and compressed by rolls 36, 38, 40 to a flexing condition where the roll 36 is spaced from rolls 38, 40. The set 30 functions as set 28 but is inverted so that the roll 36 contacts the opposite surface of the strip 10. Either side of the roll sets 28, 30 there are positioned deflecting rolls 56, 58 which are vertically tiltable and angularly adjustable. Also, the rolls are mechanically shaped to change the crown of the rolls. These rolls are used to vary the unit tension of the strip in the roll bite of roll sets 28, 30. Shape detecting rolls 60, 62 are provided to detect the horizontal transverse flatness profile of the strip passing from roll sets 28, 30. A control computer (64), Fig. 2 (not shown), receives signals from the detecting rolls 60, 62 of the non-flatness of the strip from units (66), (68), and signals of tension values from the tension bridles 12, 14 from units (70), (72), and signals from piston and cylinder assemblies 46, 52. The data received is then used to remove totally or partially the non- flatness from the strip by changing the tensioning and/or flexing operations.
