Abstract: 1,238,178. Moulding sheet material; laminates. TAKIRON KAGAKU K.K. 21 Aug., 1968, No. 40095/68. Headings B5A and B5N. Resinous sheet material is simultaneously surface finished, e.g. embossed, and laminated by pressing it between members heated by the passage of a direct or alternating electric current. In one embodiment (see Fig. 2, not shown), thermoplastic sheet material comprising a plurality of individual layers is pressed between polished and/or embossed metal plates backed by coolable platens and connected in series to a suitable current source. In operation, the plates are first pressed lightly against the sheet material and are then heated to the required temperature after which the current is discontinued. The plates are then pressed firmly against the material and the platens cooled to set the pressed material. Finally, the cooling is discontinued and the platens retracted to allow removal of the sheet. In an alternative embodiment the sheet material is passed between a pair of metal bands, each of which is backed by a coolable press platen, the bands being connected in series and to a source of power by shoes which contact opposite edges of the bands. In operation, the sheet is indexed between the platens by the belts, the belts stopped the pressing effected as described above, and the bands restarted to index the pressed sheet from between the platens. PVC sheets may be laminated together in this manner and polypropylene cover sheets may be laminated to a plywood core in similar fashion.

Abstract: 1314015 Joint making and packing; pipe joints BRITISH ROPES Ltd 22 June 1970 [2 July 1969] 33488/69 Headings F2B and F2G A sealing means for providing a fluid-tight connection between a pair of hollow members (e.g. pipes), comprising an annular housing arranged to be rigidly secured to one of the pipes, a floating ring adapted to be mounted in the housing for limited radial and axial movement relative thereto and arranged to make sealing contact with the other of the hollow members, the minimum internal diameter of the floating ring being less than the minimum internal diameter of the housing, the housing having an annular recess for receiving projections on the floating ring and being adapted for retention of said projections in the recess thereby to retain the floating ring in the housing, and a first resilient annular sealing member located between the housing and the floating ring. The floating ring is defined as a ring which is not rigidly attached to the housing or either of the hollow members.  As shown (Fig. 3) the annular recess 2 in the housing 1 has a plurality of circumferentially spaced plates 8 welded thereto so that the floating ring 3 may be engaged bayonet fashion, a bolt 3f being subsequently inserted in the housing to abut a projection on ring 3 to prevent rotation (and thereby prevent removal of the ring 3 from the recess 2). A resilient seal 4 is secured to the housing and is shown in its relaxed state in Fig. 3. In practice the sealing surface 6 abuts face 5 of ring 3. A further resilient seal 7 on the ring 3 is arranged to abut a further hollow member (not shown) so as to provide a fluid tight joint which will tolerate some degree is misalignment between the housing and said further hollow member. The geometry of ring 3 is such that when fluid under pressure is conveyed through a pipe joint incorporating the sealing means, the pressure acts to urge the ring 3 firmly against said further hollow member.

Abstract: 1320561 Transmit-receive circuits, echo suppressors, gating circuits INTERNATIONAL COMPUTERS Ltd 1 Jan 1971 [28 Jan 1970] 4054/70 Headings H3T H4L, and H4R In a system in which signals are fed to a load which at times acts as a source of signals, the signals from the load are derived via a field effect transistor amplifier, current flow in which is disabled when the signals are being fed to the load. The use of such a transistor arrangement reduces noise. In the circuit shown, which is applicable to transmit/receive arrangements in a radio or line system and in a common read/write recording head system, a pulse from 8 which enables a signal source 1 feeding load 2, passes inverted to the transistors 4 and 5 associated with the pre-amplifier 3 to disconnect its current path and so prevent direct feed-through from the source to the amplifier output. One of the transistors 4 and 5 may be omitted or they may be replaced by mechanical contacts. Inductors and resistors may be connected in series with the gates of the transistors to reduce voltage spikes. Transistors 4 and 5 may be switched to different FET circuits.

Abstract: 1320684 Feeding sheets G J COKE [trading as GECO MFG CO] 21 Oct 1970 [21 Oct 1969] 51630/69 Heading B8R In apparatus of the kind known as a suspension feeder which operates by suction to lift a top panel from a stack and hold it suspended against an endless conveyer by which the suspended panel is transported to a processing machine, a vertically-movable switch-actuating rail 40, Fig. 3, extends along the length of a suction box and is lifted, at least, at one end by a suspended panel being transported and drops when the rear edge of the panel clears the rail, the dropping of the rail causing the switches to be actuated so as to restart a lifting operation of the stack table. A suction box 25 connected to a fan 12 and having suction nozzles 29 is supported at its corners by springs 14 and has at its ends brackets 33 supporting rollers 31 around which pass the conveyer belts 34, there being one belt between two adjacent rows of nozzles 29. As the stack table 50 is raised, e.g. by mechanism as described in Specification 1,107,622, the top sheet of the stack is engaged and held by the suction nozzles 29 and the structure 13 comprising the box 25 and belts 31 is raised against the action of springs 14. This causes plates 20 at the corner supports to actuate switches (19, Fig. 2) which first stop the stack raising and then cause a slight lowering of the stack, so that the top of the stack does not interfere with forward movement of the separated sheet. If there is more than one stack on the table 50, a sheet is separated from each of the highest stacks of the same height. The separated sheet or sheets engages and lifts the rail 40 from the position shown dotted, Fig. 3, to the full line position. Near its ends, the rail 40 is attached to rods 41 carrying plates 47 each of which operates a switch 48 so arranged that when the sheet is held by suction against the belts 34, a motor 37 is actuated to drive the belts and feed the sheet to a conveyer 17. When the trailing edge of a sheet (or the trailing edge of the last sheet of simultaneously separated sheets if there is more than one stack) passes beyond the rail 40, the rail drops to actuate all the switches 49 causing the drive to the conveyer belts to be stopped and the stack-raising devices to be rendered operative to start another cycle of operations. The table 50 may be one of a pair which can be slid alternately on rails 52 into feeding position or into a reloading position. Means, not described, may be provided to avoid jamming if an underneath panel sticks to that panel separated by the suction devices, by stripping off the adhering panel or stopping the feeder.
