Filed: 1921-02-28
Abstract: 179,358. Roe & Co., Ltd., A. V., and Chadwick, R. Feb. 28, 1921. Planes, construction of; regulating altitude.- A plane having variable camber comprises longitudinally divided hollow wing spars, the parts of which are hinged together at their lower edges and are adjusted by mechanism housed within the spars. The fixed part 2 of a front spar is attached to the main portion of the plane, and the movable part 2a carries a nose 1<a>. The hinges 5 are preferably piano hinges. Adjustment is effected through pivotally-mounted bolts 6, 10, which engage, by oppositely-handed screwthreads, a barrel 15 carrying a sprocket-wheel 16. An endless chain passes alternately over and under these sprocket-wheels, being prevented from jumping off by guards 33, and is adjusted by a sprocketwheel 22 on a shaft 20 carried in the cock-pit of the machine. The trailing edges of the planes are adjusted in a similar manner by chains 23 passing over a sprocket-wheel 21 on the shaft 20. The shaft 20 is rotated through bevel-gear by a hand-wheel 17.

Filed: 1974-02-14
Abstract: 1454028 Vinyl chloride BASF AG 14 Feb 1974 [15 Feb 1973] 6676/74 Heading C2C Vinyl chloride is produced by cleavage of dichloroethane to form a product mixture of vinyl chloride and HCl together with unreacted dichloroethane and unsaturated impurities, removal of the HCl formed, and adding 0À01-1 wt. per cent of Cl 2  (based on the dichloroethane originally used) to the reaction mixture after the cleavage reaction to react with unsaturated impurities and subsequently recovering the vinyl chloride by separation from the dichloroethane and chlorinated impurities. The Cl 2  is preferably dissolved in some of the unreacted ClCH 2 CH 2 Cl after separation from the vinyl chloride and the resulting mixture is added to the reaction mixture after removal of HCl. Alternatively Cl 2  may be added prior to the removal of HCl. The reaction with Cl 2  may be performed at 20 to 100 C. using 0À1-0À6 wt. per cent Cl 2 , in order to react with butadiene, chloroprene and monovinylacetylene impurities in the vinyl chloride.

Abstract: 787,802. Moulding capsules. FARBWERKE HOECHST AKT.-GES. VORM. MEISTER, LUCIUS & BRUNING. March 12, 1954 [March 12, 1953], No. 7334/54. Class 87(2). [Also in Group XVII] Capsules filled with liquid or paste are produced by positioning sheets or webs 1 and 2 of synthetic thermoplastic material between a lower fixed clamping frame 3 and an upper vertically-movable clamping frame 4 in which are slidably mounted gridlike electrodes 5 and 6 fitted with moulding elements 7, 8 defining opposed cavities. The frame 4 is then moved downwardly to clamp the edges of the sheets, the electrodes are moved inwardly to the position shown and a filling nozzle 9 is moved to the right into sealing engagement with edge portions of the sheets which overlie a conical charging opening formed by mating recesses in the frames 3, 4. The liquid or paste, which may be heated, is then forced between the sheets through the nozzle so that the sheets are expanded into the moulding cavities, the electrodes are moved further inwardly to expel excess material which escapes through a valve 10, the nozzle 9 is retracted and, if desired, the upper frame 4 is moved upwardly a short distance. Welding of the sheets is then effected by applying a high-frequency voltage to the electrodes and moving them inwardly a further short distance to compensate for the difference between the combined thicknesses of the unwelded sheets and the thickness of the weld. The filled capsules thus formed are separated or partially separated by knives 11 operating in recesses 12 in the electrodes or cutters formed on the electrodes, after which the electrodes and upper frame 4 are retracted to allow the capsules to be removed or ejected. If the capsules are formed from webs and are not completely separated, reciprocating grippers may be used to remove the chains of capsules from between the frames and at the same time feed fresh portions of the webs into position for filling and welding. The elements 7, 8 are preferably made of dielectric material and formed with air escape passages 15 which may also be used for the supply of compressed air to eject the filled capsules. The elements 8 may be provided with adjustable spring-loaded buffers 14 which determine the volume of excess filling material displaced when the electrodes engage the sheets. Alternatively, the elements 7 and 8 may be made of metal and suitably embossed or engraved so that designs or indicia are formed on the surfaces of the capsules. The sheets 1 and 2 may be preheated and, in the case of thick sheets, premoulded by the admission of compressed air before the filling operation.

Title: Improvements in or relating to means for controlling searchlights from a distant station
Filed: 1919-03-25
Abstract: 157,481. Willans, P. W. March 25, 1919. Order-type apparatus.-In apparatus for moving searchlights at one or more distant stations so that their beams always intersect the searchlight beam or the sighting line of a telescope at the controlling station at a predetermined height, electrical connexions are provided for checking the movement of the block controlling the searchlight at a distant station relatively to the movements of a corresponding block at the controlling station. In the arrangement shown, the blocks Q, q at the controlling and distant station P, p respectively are movable along guides B, b which are movable along guides A, a at right-angles to the guides B, b. The guides B, b carry brushes D, d moving over rheostats C, c parallel to the guides, and the blocks Q, q carry brushes F, f moving over rheostats E, e carried by the guides B, b. The rheostats are all connected in parallel so that the galvanometers G, g inserted in connecting leads D, d and F, f indicate whether the block q is in the position corresponding to the block Q. Any necessary adjustment of the block q may be made by hand, or the galvanometers may be replaced by polarized relays which bring into operation motors actuating the guide b and block q or operating indicators to show the direction of motion required. The movements of the blocks Q, q may be equal or proportional to one another. An adjustment to vary the height of intersection of the beams may be effected without altering the position of the searchlights by adding electrically to the brushes D, F, Fig. 2, potential differences inversely proportional to the height of intersection and diminishing the potential gradients of the rheostats c, e relatively to the rheostats C, E by an amount inversely proportional to the height of intersection. The connections necessary in the case of the rheostats C, c are shown and described in the Specification.

[Class 4] A de-icing apparatus for aircraft is characterised by the fact that it comprises a plurality of catalytic heaters adapted to heat the parts to be protected, to which heaters fuel is supplied from a distance. A tank 1 containing liquefied propane or other liquefied combustible gas is connected to a compensated pressure-reducing valve 2, a pressure gauge 3 and a manifold 4 from which extend tubes 5-9, each connected to a catalyst element 10-14 respectively. Each catalyst element comprises a metal casing 15 fitted with a perforated fuel-supply pipe 20 and provided internally with a frame 16 having a grid 17 and an asbestos or similar filler 18 covered by a layer of asbestos cloth 19 impregnated with an oxidation catalyst such as platinum salts and exposed to atmospheric air. Embedded within the cloth 19 is an electric resistor wire 21 for priming the catalytic combustion of the fuel by causing a preliminary heating of the cloth 19. The power supply 22 is connected through a switch 23 and a shunt indicator lamp 27 to one end of the resistor 21, the other end of which is connected to a thermostat switching device which is arranged to connect to the power source through a lead 25 for priming purposes and, when the temperature due to the chemical reaction reaches an optimum value, to disconnect the resistor and connect the lead 25 to a lead 29 in series with a lamp 28 to indicate that the catalyst is functioning. The electric primary system may be replaced by or combined with means for supplying to the fuel supply system a small amount of gas of great catalytic response such as hydrogen. The apparatus may be adapted to operate with hydrocarbon fuels by lining the bottom of each casing with an absorbent material.
