Title: Method of and device for manufacturing hollow panels
Inventor: KULAKOVSKY VLADIMIR ALEXANDROV
IPC: B32B27/00
Filed: 1965-08-10
Abstract: 1,060,813. Laminating. SPETSIALNOE KONSTRUKTORSKOE BYURO PO OBORU. DOVANIYU DLYA PROMYSHLENNOSTI STROITELNYKH MATERIALOV. Aug. 10, 1965, No. 34217/65. Heading B5N. A method of manufacturing hollow panels comprises feeding a web 8 to interweave between parallel cores I to produce an internal corrugated layer for the panel, feeding two other webs 9, 10 along opposite sides of the cores to form the outside walls of the panel, pressing the said webs with the cores therebetween, moving forward the pressed webs with the cores, and returning the cores one at a time to their initial positions so that the pressed webs are not returned to their initial positions. In a device described for performing the method the cores 1, which may be heated, extend between vertically reciprocable pressing plates 2 mounted on a reciprocable bogie 3 and acting via endless metal belts 6. In operation the webs 9, 8 and 10, which are of thermoplastic material, are fed above, between, and below the cores 1 respectively and are fed forward with the cores 1 as these travel forward under the action of hydraulic cylinders 7. The plates 2 are then pressed together to press the webs and the bogie 3 moves forward together with the plates 2 which carry along the cores and the material being pressed. After pressing the plates 2 are separated and returned to their initial positions. At the same time all but one of the cores 1 are again moved forwardly to feed more material to the pressing plates, the odd one core being moved back at 6 to 10 times the speed of forward movement of the other cores. The cycle of operations is then repeated with each core being moved back in turn.

Title: Electro-pneumatic door opening and closing apparatus
IPC: E05F15/00
Filed: 1959-10-09
Abstract: 879,445. Door operating appliances. WESTINGHOUSE BREMSEN-G.m.b.H. Oct. 9, 1959 [Oct. 11, 1958] No. 34271/59. Class 65(1). An electro-pneumatically controlled door-operating apparatus comprises a main pneumatically actuated door-operating piston the door closing movement of which is impeded and cushioned by a trapped volume of compressed fluid and is completed only after the release of the trapped fluid, the trapped fluid being connected to a supply reservoir and bounded by an auxiliary piston which is mounted in the path of travel of the main piston and the end position of which is determined by a stop. The apparatus of Fig. 1 is shown in the "door open" position, the auxiliary piston 28 being mounted on the piston rod 18 of the main piston 17 and held in the end position, which is determined by stop 28a, by the pressure of the trapped fluid in the cylinder space 30 and by a spring 29. During the opening operation compressed fluid, e.g. air, is supplied through a pipe 6, and passes to the space 30 through an annular by-pass pipe 32, magnetically releasable non-return valve 12 (Fig. 3, not shown), and port 33, and to the space 35 between the pistons 17, 28 through a chamber 34 and passage 36 between the piston 28 and the piston rod 18. Fluid in the chamber 20 in front of the piston 17 is evacuated through a pipe 5, the final stage of the opening movement being damped by the means 22, 23. When the door is to be closed compressed fluid is supplied through the pipe 5 and moves the piston 17 until its motion is impeded by the auxiliary piston 28, fluid in the space 35 evacuating through the passage 36 and pipe 6. The final closing movement occurs when the trapped fluid is released by the magnet valve 12 which is operated after a predetermined time-lag by a time-switch relay 9 (not shown) brought into operation by the pressure in the pipe 5. Alternatively the magnet valve 12 may be operated by a manual switch. A modified apparatus is described (Fig. 2, not shown) in which the main piston rod moves out of its cylinder to effect the door-opening operation. Two electro-pneumatic control circuits are also described.

Title: Process for producing hydrocarbons of high anti-knock value and boiling within motorfuel boiling range from olefinic gases
IPC: C07C2/18
Filed: 1937-12-10
Abstract: 511,181. Polymerizing olefines ; hydrogenating olefine polymers. UNIVERSAL OIL PRODUCTS, CO. Dec. 10, 1937, No. 34274. Convention date, Aug. 23. Drawings to Specification. [Class .2 (iii)] Motor fuel hydrocarbons are produced by catalytic polymerization of a continuously flowing stream of normally gaseous olefinic hydrocarbons which, while in direct contact with the catalyst under elevated temperature and pressure, are brought into indirect heat exchange with a normally liquid cooling medium of substantially constant boiling point which boils under controlled superatmospheric pressure at the desired polymerization temperature by heat transferred thereto from said polymerization, whereby a substantially uniform temperature is maintained. C4 fractions are preferably polymerized with pre-calcined mixtures of phosphoric acids and siliceous adsorbents at 115-215‹C. and' 33-51 atmos. or more to give iso-octenes. These are hydrogenated in reactors wherein reaction heat is removed as indicated above. The olefinic charge is purified as by alkali washing and passed over the catalyst, if desired together with recycled butanes. The catalyst is contained in a bundle of vertical tubes terminating in upper and lower headers, and surrounded by a chamber for the boiling cooling medium which communicates with a drum for separating entrained liquid from vapour, and a condenser for returning condensed vapour, such apparatus forming the subject- ,matter of Specification 511,349. The product 'is debutanized, fractionated to remove higher boiling hydrocarbons, and the octenes hydrogenated in two stages at about 150-215‹C., for example, with nickel carbonate precipitated. on kieselguhr and reduced at 400‹C. with hydrogen. Recycling of hydrogen in the second stage may be employed so that an excess is present. The hydrogenating apparatus is similar to the polymerization apparatus referred to above and also forms the subject-matter of Specification 511,349. In an example, a C4 fraction is passed through a solid phosphoric acid catalyst, the inlet temperature and pressure being 146‹C. and 44 atmos., and the outlet pressure 42.2 atmos. Water boiling under an excess pressure of about 3.2 atmos. is the cooling medium. The iso-octene fraction is hydrogenated at 190‹C. first at 4, then at 6.1 atmos. The cooling medium is water boiling under an excess pressure of 11À35 atmos.

Title: Cathode ray tubes for television apparatus
IPC: H01J29/02
Filed: 1934-11-30
Abstract: 445,372. Discharge apparatus. SHORNEY, A. B., Shebbear, Beaworthy, Devon. Nov. 30, 1934, No. 34410. [Class 39 (i)] A cathode-ray tube for television transmitting apparatus has a photo-electric screen consisting of a cellular anode 8, Fig. 1, and a cellular photo-electric cathode member 7, an insulated conductor 12 extending into each pair of cells 9, 14, the anode cells 14 being closed by a plate 15 which is impervious to actinic rays and is provided with apertures closed by material 16 pervious to X-rays but not to cathode rays, the arrangement being such that when the screen is scanned by cathode rays, X-rays are produced in the anode cells and discharge the energy stored in those cells. The cathode member 7 may be of glass with conical or pyramidal cells, the lower ends of which are each formed with an aperture. The walls of each cell 9 are silvered and coated with sodium, the part near the aperture being left free of coating. In a modification, the deposits are formed only on the inner surface of the cover plate 13 and in the upper ends of the walls, connection between the cells and a terminal being obtained by metal strips 17, Fig. 3. The conductors 12 are of wire coated with lead glass, and are secured in the apertures by enamel, a part of the glass coating being removed by chemical action. The anode 8 consists of a sheet of lead or lead alloy with rectangular cells, and is closed by a metal plate. The apertures containing material 16 pervious to X-rays are in line with the conductors 12. The anode cells may contain gas or a metallic oxide which becomes conductive on exposure to X-rays. A thin film of metal may be deposited on the outer surface of the plate and of the material 16. The parts of the conductors inside the cathode cell acquire a positive charge as the other ends are negatively charged by induction from the anode. A picture focused on the cathode produces electrons which pass to the conductors, and the charge on the conductors is caused to leak through the gas &c. filling by X-rays produced in the anode cells by the scanning cathode rays. In another arrangement, the cathode member 7 is of metal and is insulated from the anode.

Title: Improvements in a method of and means for the manufacture of cartridge cases for firearms
IPC: F42B5/30
Filed: 1954-11-29
Abstract: 765,502. Moulding cartridge c ases. LEFEBVRE, J. M. Nov. 29, 1954 [Nov. 30, 1953], No. 34485/54. Class 87(2). [Also in Group XXI] A cartridge case comprising a base and a thin tubular portion is moulded in one piece from thermoplastic material, e.g. ethyl cellulose, by slowly injecting the material at a temperature below 200‹C. at a level in the mould corresponding to the base of the cartridge, the mould being cooled to a temperature below 25‹C. The mould comprises an upper part 1 and a bottom 5 which is movable and closes the mould under pressure, the magnitude of such pressure being less than usually necessary in injection moulding machines due to the lower injection pressure. Fig. 1 shows part of a multi-cavity mould. The material is injected through a main conduit 6 and is dispersed through secondary conduits 8 to inlets 7 spaced round the part of the cavity 1b in which the base, including the rim of the cartridge is moulded. This dispersion permits the injection of viscous material and avoids the formation of a seam in the tubular wall of the moulded cartridge case, since the material flows up the wall of the cavity 1a, in which the tubular portion is moulded, from several points in the cavity 1b and tends to solidify in concentric layers. The inside of the cartridge case is shaped by a core 2. Coolant, e.g. mains water, is circulated through a cavity 17. The crosssections of the secondary conduits 8 may be proportional to their length. The cavity la may have a slight draw taper. The relatively low moulding temperature is favourable to the incorporation of a primer, Fig. 3, during the moulding process, since it reduces the risk of explosion. The end of the primer fits in a bore 2a in the centre of the core 2 and a pin 3, slidable in the bore 2a, abuts the end of the primer. When the mould closes the movement of the bottom 5 through the distance d crushes the end of the primer against the end of the pin 3 and against the surface of the bore 2a, so providing a seal against the entry of injected plastic material, and the squeezing of the primer and the pressure of the injected material cause the wall of the primer to cave in, Fig. 4, resulting in the primer being firmly incorporated in the moulded cartridge case. To minimize the risk of explosion a plastic heat insulating ring 16 may cover the primer. The pin 3 operates as an ejector when the mould is opened, in which function it may be assisted by a tubular member 4 which fits between the core 2 and cavity 1a and, during the injection moulding operation, defines the top edge of the moulded cartridge case.
