[Also in Divisions B3 and B6] Articles are moulded from sheet material by drawing the sheet between a rigid die and a die comprising a laterally confined body of resilient material such as rubber or polyurethane. The sheet may comprise a single layer, a plurality of superimposed layers separable after forming to produce a series of articles (see Figs. 5 and 6, not shown), a plurality of superimposed layers which are mechanically interlocked during the forming to give a multi-walled article, or a laminate comprising bonded layers. The material used may be polypropylene, polystyrene, P.V.C., cellulose acetobutyrate, an A.B.S. copolymer, polymethylmethacrylate or polycarbonate. Laminates that may be formed comprise an acrylic-polystyrene composite or a composite comprising metal foil sandwiched between two outer plastics layers. In the example shown in Fig. 2, a sheet 10 is drawn between a rigid male die 3 and a confined flexible body 2. In the example shown in Fig. 4, the sheet is gripped between rings 19 and 20 and drawn into the cavity in the multi-layered resilient body 16, 17, 18 by a rigid male die 11. In an alternative embodiment the sheet may be embossed by using a suitably configured plate instead of a male die.

Title: Electrical networks for the suppression of echoes and the like in electrical signalling systems
IPC: H04B3/40
Filed: 1947-11-14
Abstract: 639,164. Impedance networks. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Nov. 14, 1947, No. 30308. [Class 40 (viii)] A wave-form correcting network for suppressing two or more echo signals comprises a first and second delay network or line 16 and 17 connected in cascade and having inserted between them an impedance 18 such that the impedance presented to the first delay network by the combination of impedance 18 and network 17 differs from the impedance of network 16, whereas the impedance presented to network 17 by the combination of impedance 18 and network 16 is equal to the impedance of network 17. The terminal 11 is connected to the signal line by a matching impedance 12 and terminal 13 is a termination. A signal in the line will then produce reflections at impedance 18 and terminal 13 which will give delayed signals which can be adjusted to cancel out echo signals. No reflection occurs at impedance 18 for a signal passing from right to left and thus the setting up of a long series of reflections is avoided. Reflections with phase reversal can be obtained by making the termination 13 a short instead of an open circuit and placing the impedance 18 in shunt instead of in series. By using two impedances 18 one in shunt and one in series it is possible to obtain the desired matching without requiring networks 16 and 17 to be different. Specifications 630,022, [Group IV (a)], 630,200, [Group XL (c)], 635,287 and 635,381 are referred to.

Title: Improvements in or relating to fluid pressure operated jacks
IPC: B64D1/04
Filed: 1936-11-11
Abstract: 486,955. Retractable alighting gear for aircraft. AUTOMOTIVE PRODUCTS CO., Ltd., and PARKER, S. M. Nov. 11, 1936, No. 30801. [Class 4] [Also in Group XXIX] The undercarriage of an aircraft is retracted and extended by a plurality of fluid-pressure jacks operating in unison, each jack having end position locking means released by the fluid-pressure and means for preventing operation until all the other jacks are freed by their locking means so that all the jacks commence operation together. In the Figure, the plungers 12, 13 of a pair of jacks 10, 11 are locked in retracted position by pairs of locking levers 20 engaging under flanges 18 on the plungers. Pressure fluid is supplied by a pipe 40 to valve cylinders 29, 29a on each jack, each cylinder having a piston 26, 26a for operating the locking levers 20 and for controlling a pair of mushroom valves 31, 34. Pipe connections 46, 46a supplying pressure fluid to the upper ends of the jacks are connected in each case to the valve cylinder of the other jack, the admission openings to these pipes being initially closed by the valves 34. Considering first the action of the valve mechanism on jack 10, admission of pressure fluid by the supply pipe 40 lowers piston 26 to open the locking levers 20. At the moment when the jack plunger is released, valve 31 seats in an aperture 20 and cuts off the pressure supply to piston 26, and valve 34 admits fluid to connection 46 to apply pressure to the head of jack 11. Similarly, pressure is not applied to jack 10 until the levers 20 have released jack 11. Consequently, neither jack can operate until both are released, and both commence operation together. To contract the jacks, fluid is applied to their lower ends by a pipe 41, the flanges 18 snapping past the locking levers 20 when fullycontracted. If the jacks are locked in both end positions, the interlocking valve systems are duplicated. In an arrangement of four jacks, the jacks are connected together in pairs as in Fig. 1, and the pairs are similarly interconnected by supplementary valve devices associated with each pair. The application of the invention to jacks having locking means as described in Specification 434,493 is also described.
