IPC: F02G1/044
Filed: 1946-01-14
Abstract: 605,992. Driving-gear; hot gas engines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Jan. 14, 1946, No. 1192. Convention date, May 8, 1941. [Classes 7 (i) and 7 (ii)] A hot gas reciprocating engine has opposed cylinders 1 arranged in pairs in a ring round the power shaft 6 and the ends of the pistons roll through rollers 3 on a pair of sinusoidal cam discs 4 mounted on the shaft 6, and angularly adjustable relatively to each other to alter the phasing of the pistons and effect reversal of the engine. The rollers 3 are preferably tapered as shown. A coil 11 is energized during running by a small generator to ensure that at all times the rollers 3 remain in engagement with the tracks 4. Between each pair of cylinders is located an assembly comprising a regenerator 12, heater 13, and cooler 14. The regenerator is preferably. of porous material of good heat conductivity, high capacity and minimum resistance to the medium flowing through; it may be of the kind described in Specification 535,553. The cooling medium may be air or water. If air is used, the cooler may be used as a preliminary heater for combustion air or for heating the building or vehicle in which the engine is mounted. If water is used, the steam formed may be used for driving one or more auxiliary units or for central heating. In the form shown, the pistons of one ring lead those of the other by 90 degrees and the shaft 6 makes one revolution for every two complete piston strokes. This ratio may be increased in cases where a slow shaft speed is required.

Title: Improvements in and relating to a rectifying filter for a telephone fee meter
IPC: H04M15/28
Filed: 1958-01-14
Abstract: 837,160. Automatic exchange systems. SODECO SOC. DES COMPTEURS DE GENEVE. Jan. 14, 1958 [Jan. 22, 1957], No. 1280/58. Class 40 (4). Metering at a substation is effected by burats of 16 kc/s. pulses and the invention is concerned with accurate response to metering burats. A resonant circuit passes pulses of the required frequency to a rectifying and voltage doubling circuit 5, 6, 7, 8 which feeds the emitter-base circuit of a transistor 9, the collector circuit of which includes the winding of a meter 10. The end of the burat of pulses produces an immediate cessation of current through the meter. If the substation is close to the exchange the voltage on the line may be high. Gas tube 4 then ignites, so detuning the filter circuit which passes on a limited amount of current. The tube 4 may be in parallel with condenser 2 and the transistor circuit may be modified in detail (Figs. 2 and 5, not shown). The transistor may be replaced by a resonant circuit 11, 12, Fig. 3, which produces a rapid discharge of condensers 7, 8 at the end of the burst of pulses.

Abstract: 130,354. Bradley, P. R. Jan. 25, 1918. Coating-machines. - In a method of applying dope and other liquids to parts of aircraft, the parts are first dipped bodily in tanks containing the dope and then removed to an airtight drying-oven from which the vapours of the solvent are drawn off and condensed. Fig. 1 shows, in plan, the arrangement of the building in which the operations are performed. The building is divided into a workroom 1, a tank-room 2 having a door or airlock room 10, a loading and unloading room 3, a dipping-room 8 having a door or air-lock room 9, and a drying-oven 6 to which a condensing-plant C is connected. An overhead track 7 is positioned as shown, and carries cars B supporting the aeroplane parts, which can be lowered into tanks 13 containing the dope &c. The tanks 13 are supported on rails 12 in a pit 11, whereby they can be moved into position beneath the track 7. The cars 13 can be operated by a cable 14. Fig. 3 shows the pit 11 with one of the tanks 13 and a car B with its device for holding and lowering the areoplane parts into the tank 13. The car comprises a frame 15 having wheels 16 which run on the track 7. The holding and lowering means comprise a frame 17 carrying racks 18 which can be raised and lowered by gears connected to an operating-shaft 25 carrying a clutch 28 adapted to be connected to, and disconnected from, a corresponding member on a power shaft. A friction band 27 round a brake wheel 26 on the shaft 25 enables the frame 17 to be held at any height. The aeroplane sections to be dipped are held in frames 31 suspended from the frame 17. When the parts have been dipped, the cars are moved into the drying-oven, from which the vapours are removed by a condensing-plant shown in Fig. 2. A pump 33 is connected by pipes 34 to the oven and leads into a coil 35 surrounded by a steam jacket 36. The vapours then pass into a condensing-coil 39 connected with a receiver 44 from which the solvents are withdrawn into a container 45. The wings of aeroplanes to be dipped are provided with drain-holes bored through the wood frames and provided with metal sockets. The wings are kept in the tank until the dope has penetrated the fabric, the dope inside the wings being drained off through the openings, which are subsequently plugged. After the requisite number of coats of dope have been applied, the tank is replaced by one containing varnish. The door between the drying-oven and dipping-room is then opened to raise the temperature of the latter to about 90‹ F.

Abstract: 1423817 Laminates; fabric covered foam resin articles BRIDGTOWN INDUSTRIES Ltd 9 1973 [13 Jan 1972 21 April 1972 15 Dec 1972] 1744/72 18581/72 and 57886/72 Headings B5N and B5A [Also in Division A4] A padded article, e.g. a car seat, roof lining or door trim, is produced by providing a piece of permeable fabric 1 with a backing comprising a layer of preformed flexible and resilient foam 2 material and a flexible film 7 of impermeable material, the layer being between the piece of fabric and the film, and forming a flexible and resilient foam material 8 behind the backing which adheres to the backing. The permeable fabric may be woven, knitted or non-woven, e.g. a warp-knitted brushed-nylon fabric. The layer of foam material, which may be not more than 15 mm. thick and may be a polyurethane foam, may be bonded to the fabric by means of an adhesive or by flame bonding. The flexible film of impermeable material, e.g. polyurethane, may be applied as a liquid by a blowing process in which the liquid is extruded through a narrow slit and forms a film, e.g. of thickness 0À002-0À005 mm., which becomes bonded to the fabric. The foam behind the backing which is preferably a polyurethane foam, may be formed in a mould in which the backed fabric, which may have a non-planar contoured shape, is an insert. The hardness and density of the foam material formed behind and adhering to the backing may be greater than those of the foam material constituting the layer. A skirt or border may be attached to an edge of the fabric or its backing or both before the foam material is formed so that the foam material adheres to the skirt or border. The skirt or border may be a piece of fabric or PVC sheet which may be formed in situ by pouring the liquid polymer into an embossed border mould adjacent to the backed fabric or by spraying PVC on to the border mould. Alternatively the skirt or border may be attached to the assembly by means of a strip of thermoplastic material, by an RF welding process or sewing. In Fig. 11 after the backed fabric has been shaped to provide ribs by means of heated tools in a manner such that a compressed band is provided around its periphery and positioned on base 37, intermediate hinged mould part 39 is lowered, foam forming material is introduced and hinged lid 41 closed.
