Title: Improvements in electric lighting installations
IPC: H05B41/10
Filed: 1936-02-22
Abstract: 456,803. Supply systems for discharge and incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Feb. 22, 1936, No. 5392. Convention date, Feb. 23, 1935. [Class 38 (iv)] A lighting unit comprises a discharge lamp 14 in parallel with an incandescent lamp 15 and supplied from a transformer 10 the primary of which is traversed by a constant current. The discharge device starts at a low voltage which gradually builds up to the normal operating value at which it operates also as a voltage regulator for the incandescent lamp. Should the device fail to start through being too cold the voltage in the circuit rises to a value sufficient to operate a relay 16 which connects a further incandescent lamp 20 in parallel. When the device does start the drop in voltage de-energizes the relay 16. In a modification of this the lamp 15 is in series with the operating winding of a relay which controls the connection of the discharge device 14 and relay 16 so that failure of the lamp 15 causes de-energization of the circuit. A film cut-out is connected across the transformer secondary to short circuit it when such a break-down occurs. In a further modification the lamps 15, 20 are connected to a lower voltage tapping and the relay in circuit with the lamp 15 has double contacts.
Patent GB-975506-A (GB)
Title: An improved method of fabricating aluminium articles by the hot rolling of aluminiumpowder
IPC: B22F3/18
Filed: 1961-02-14
Abstract: In a rolling process of forming sintered aluminium sheet, aluminium powder having a minimum particle size of 1 mm. and coated with a film of alumina, is heated prior to rolling to a temperature above the melting point of the aluminium but not so far above that the oxide layer is broken, or that the aluminium remains liquid during rolling. The alumina film is formed by heating the aluminium particles in an air stream and the particles are then fed either horizontally or vertically into the rolling mill.  Alternatively the particles may be enclosed in a sheath and fed into the mill. The alumina film prevents sintering and coalescing of the particles prior to rolling and forms a dispersed phase in the sintered sheet which may be further rolled and annealed.

Title: Manufacture of a web or mat from glass fibre
IPC: D04H1/72
Filed: 1962-02-13
Abstract: 961,631. Forming fibre laps; agglutinated fibrous fabrics. W.H.W.SCHULLER. Feb. 13, 1962 [Feb. 14, 1961; May 6, 1961], No. 5420/62. Headings D1F, D1N and D1R. In the continuous production of (bonded) glass fibre mats by a method in which staple glass fibres are carried in an air stream from a position of manufacture to a position of deposition on a conveyor belt on which the fibres are accumulated in superposed relation to form the mat, the entrained fibres are controlled by regulating the air stream so as to carry the fibres individually and separately in a zone close to the base of a conduit of inverted U-section extending between the positions. The manufacture of fibres may be as described in Specification 805, 551, the air generated by a drawing drum being used, in part at least, to convey the fibres. As shown in Fig. 1, the air carrying fibres from drum 2 moves in the direction of arrow A into a stationary, tapered, deflection nozzle 4 which reverses the direction of flow to carry the fibres near the wall 7. Fibres flowing from nozzle 4 are guided to an air-pervious belt 5 e.g. wire netting (to the underside of which suction is applied) and distributed thereon at 15 by a reciprocating guide member 13 (of inverted U-section). A series of such apparatus may be arranged successively and/ or alternately on one or both sides of the belt and, optionally, at an angle thereto and the members 13 thereof synchronously driven through chains and sprockets from a single central shaft, Figs. 2 and 3 (not shown). if one or more such apparatus fail to deliver fibres e.g. when glass rods are being replaced, the speed of the belt 5 and the reciprocating speed of members 13 are correctively reduced so that the fibre density and thickness of the mat are maintained. In a modification, Fig. 5 and Figs. 6 and 7 (not shown) for making mats at least two metres wide, the member 13 slides over stationary and mobile duct sections 28 and 29, the latter sliding over the former in synchronism with the movement of member 13. If the air flow provided by drum 2 is insufficient, additional air may be injected through a socket 38 provided with a throttle flap 39 which is controlled by the member 13 or section 29 so that it opens and closes with the telescopic system 13- 29-28: alternatively, the drum may be replaced by a fan or blower. Excess solvent of a bonding agent for the fibres may be removed in a drying oven and the agent set in a curing chamber, Fig. 3 (not shown) or the mat may be wound into a roll without setting the agent.

Abstract: 842,784. Animal stocks. HOOTON, R. H. Feb. 19, 1959 [Feb. 20, 1958], No. 5482/58. Class 81(2). A holding device for a cattle crush comprises a gate 17 extending approximately halfway up the height of the crush, pivoted at one side to an upright 12 and having a latch 26 at the other side. The upper rail 28 of the gate has a recess 29 to receive the animals neck, the recess co-operating with a further recess 37 in a transverse member 36, which is vertically slidable on a frame 33 pivoted to the top bar of the door frame by hinges 31. The frame 33 is sufficiently long to engage behind the gate 17 and be securely held by the latter when it is closed. When the gate is released, however, the frame 33, and yoke member 36, are free to pivot about the upper transverse member so that the animal is released. The vertical position of the yoke member 36 is determined by a pin 47 engaging one of a number of holes in a vertical slide 38 attached to the member 36. Inadvertent upward movement of the yoke is prevented by engagement of a pawl 42 with teeth 41 on the rod 38.

Abstract: 469,834. Coking processes; cooling coke. GRIGGS, A. R. Feb. 24, 1936, No. 5559. [Classes 51 (ii) and 55 (i)] In apparatus comprising a coking chamber 1 and a cooling chamber 2 for the re ception of the coke from a previous charge the fuel is carbonize( by the passage there through of a mixture o the products of combus tion of a considerable part of the distillation gases and the remain der of the distillation gases, the gases with drawn from the coking chamber by a fan 7 be ing delivered, after cooling, by a pipe 6 to the coke chamber 2 whence they return, by conduit 9, to the coking chamber for further combustion and recirculation through the system. Combustion is effected in a chamber 1a at the upper end of the chamber 1 by air supplied at 14, while the circulation system is provided with valved outlets 15 through which any surplus gas may be taken off. Valves 11, 12, 13 enable the coke chamber 2 to be cut out of the circuit when carbonizing the first charge or when the cooling operation is completed before the charge in the chamber 1 is fully carbonized. A modification is described in which the circulating gases pass upwardly through both the coke chamber 2 and the carbonizing chamber 1. The gases employed for the carbonizing of a charge in the chamber 1 need not be the gases produced in that chamber, but may be constituted, wholly or in part, by gases from another similar chamber. A single coke-cooling chamber may serve a number of coking chambers the charges from which may be cooled either simultaneously or in succession.

Title: Improvements in or relating to shock-resistant mounting means for frangible electrical conductors
IPC: G01K7/06
Filed: 1956-02-27
Abstract: 826,841. Thermo-electric devices. MINNESOTA MINING & MANUFACTURING CO. Feb. 27, 1956 [April 8, 1955], No. 6033/56. Class 40 (1). [Also in Group XXXVI] In thermo-electric devices, shock-resistant mountings for conductive elements of a frangible material such as lead-selenium-tellurium alloy provide cushioning, which may be combined with compression of the frangible elements. As shown, Figs. 1, 2, a frangible cylindrical thermocouple element 11 is resiliently maintained coaxially within a stainless steel sheath 13 by at least 3 thin flat metal strips 12 which form the other thermocouple element, being electrically connected to element 11 through contact electrode 22, but otherwise insulated from it. Element 11 is electrically connected to the inner conductor of a coaxial cable 18 via a contact electrode 23 and a conductor 25, whose flexibility permits differential thermal expansion between the element 11 and the metal strips 12 which are connected to the outer conductor of cable 18 within an extension tube 16 which aids cooling. Spaces between the elements are preferably filled with an inert gas to prevent oxidation of element 11. Fig. 3 (not shown) depicts a modification wherein the metal strips 12 serve only as shock-absorbent cushions, being replaced as a thermocouple element by the sheath 13, a flexible conductor connecting the contact electrode 22 with the tip portion 15 of sheath 13. In Fig. 5 (not shown) the metal strips 12 are replaced by a tubular bushing of insulating and cushioning material, e.g. glass fibre, a part of the surface area of the element 11 being exposed to permit heat transfer by radiation. In Fig. 4, compression by a resilient disc 39, located between the contact electrode 23b and an insulating washer 38 against shoulder 37 in the extension tube 16b is combined with cushioning by metal strips 12b, the ends of which remote from tip 15 are interposed between sheath 13b and extension tube 16b. In Fig. 6, element 11d which is cushioned by insulating material 41d is axially bored to accommodate a second thermocouple element 43, which is placed in tensile stress by a resilient disc 39d. An insulating seal 32 (Fig. 1) between the outer and inner conductors of coaxial lead 18 at the end remote from the device is compressed against an insulating spacer 29 by the action of a connector nut 26 engaging a threaded socket 33 having a terminal tip 34 insulatedly mounted therein for electrical connection to the inner conductor through contact 28. The metal strips 12 (Fig. 1) may be of austenitic stainless steel or beryllium copper alloy; the use of constantan is also mentioned. Contact eleectrodes 22, 23 may be of iron or carbon. Specifications 765,884, 766,999, 775,970, 826,842 and 826,843, [all in Group XXXVI], are referred to.

Abstract: 910,280. Electric heating panels. OLIN MATHIESON CHEMICAL CORPORATION. Feb. 20, 1961 [March 9, 1960], No. 6187/61. Class 39 (3). In a method of inserting a sheathed electric heating element into a multidirectional conduit 15, formed, for example, between two metal plates by welding them together in a known manner, one free end of the heating element 20 passes through tube 10 into one end 17 of the conduit, inclined to the tube 10 and connected thereto is a side tube 8 through which is directed a pulsating stream of fluid-e.g. air, water, steam, which passes over and past the element in unobstructed flow through the conduit whereby the element is caused to pass through the conduit until its free end 22 emerges at end 16 of the conduit. In an alternative arrangement the pulsating fluid is applied through nozzle 23 in the wall of housing 19 in which the heating element is initially located, and the side tube 8 is dispensed with. The conduit may have any desired cross-sectional shape but the heating element must be of such diameter that it is freely movable within the conduit. A preferred form of heating wire consists of a nickel-dichrome alloy wire wound on an asbestos core and covered in an electrically insulating but heat-conducting silicone rubber sheath. The heating apparatus may be used as a skirting board heater, or an evaporator plate for use in defrosting refrigerators. Specification 759,804 is referred to.

Abstract: 752,249. Cold separation of gas mixtures. PETTINGILL, T. K. O. Oct. 5, 1954 [March 4, 1954], No. 6312/54. Class 8(2). Cooling of at least part of a gas mixture e.g. air prior to rectification in a column 10 and prior to it being brought to its maximum pressure is effected by a cold separated constituent e.g., nitrogen in a line 13 traversing a heat exchanger 3 ; a major portion of the cold compressed air being further cooled by expansion in an engine 9 prior to entry into the column 10, where it is joined by any remaining air having been throttled to a lower pressure. As shown filtered air leaving the exchanger 3 at -190‹C. and atmospheric pressure is compressed adiabatically in a compressor 4 to 70 atmospheres at 15‹C. and is joined by an uncooled portion of air in a line 6 having also been compressed to 70 atmospheres in a compressor 7 having an aftercooler for reducing the temperature to 15‹C. The united air stream is then compressed isothermally to 400 atmospheres in a compressor 5, cooled to -40‹C. in a refrigerator 8, expanded to 5 atmospheres in the engine 9 and the resulting partially condensed air at -175‹C. is fed into the column 10. In a modification the refrigerator is eliminated and the air enters the engine at 800 atmospheres and 15‹C. Liquid oxygen is discharged through an outlet.
