Title: Device for collecting the fumes given off during the production of aluminium in a fused bath electrolysis cell with a continuous anode
IPC: C25C3/22
Filed: 1975-04-08
Abstract: 1503985 Fume removal in fused bath electrolysis ALUMINIUM PECHINEY 8 April 1975 [11 April 1974] 14338/75 Heading C7B An Al-producing S÷derberg cell is characterized by the provision of two displaceable panels 16 along its long sides which sealingly engage the anode sheath 4 at their upper edges and which are spaced at their lower edges from the side of the cell to allow air ingress, and at each end a fixed panel 17 which is sealingly closed laterally by the panels 16. The space enclosed by the panels covers the electrolyte surface, and is connected at least at one end of the cell to a suction and gas-treatment device. Fig. 2 shows the fixed panel and gas collection devices; Fig. 4 is a transverse part-section partelevation, the references with apostrophes showing the panels 16 displaced for cell access. Each panel is pivoted on an arm 21, 22 and is lifted by a crank arm 29 connected to a jack 33, 34. Part 36 is a tubular stiffener extending the length of each panel. Parts 19 are seals. Each panel 16 has a lateral extension 46 which in use forms an extension of the panels 17. A counterweight 25 balances panels 16. A horizontal gas collection channel 55 with orifices 50 extends the length of the anode sheath 4 and is connected at least at one end to a gas collector 18, Fig. 2. The anode sheath 4 may have a skirt 12 around its base for collection of anode fumes, which are drawn off at 15. These fumes may be consumed in a burner 13 inside the hooded space, the hood gases forming the combustion support gases for this by way of orifices 14. The gases may be collected in concentric channels which are common to pairs of adjacent cells.

Title: Improvements in rotary tools actuated by compressed air
IPC: B23B45/04
Filed: 1944-07-27
Abstract: 580,931. Lubricating air-driven vane motors of rotary tools. VICTOR PRODUCTS (WALLSEND), Ltd., MANN, R. W., and WILES, R. C. July 27, 1944, No. 14381. [Class 12 (iii)] A lubricating arrangement for a compressedair rotary tool driven by a sliding-vane motor consists in branching part of the air supply to the vane slots with such air passing a lubricant supply element comprising an exposed partlength of wick through which the air flows while the remainder of the wick extends through a compressing gland into a closed lubricant chamber. The air pressure slowly leaks into the lubricant chamber so that on stoppage of the motor this air will force a greater quantity of lubricant into the exposed length of wick, whereby on restarting the motor a richer supply of lubricant is entrained during the initial stage. As shown, the main part of the air supply passes by ports f' in a sleeve of a spigot member f to a chamber b leading to the admission side of the sliding-vane motor, but a small portion (about one-fiftieth) passes by a restricted port f<2> into an exposed length of a tubular oil wick g and through the material thereof to a chamber m having a duct u leading to a channel u' formed in the interior side face of the motor casing which channel communicates with the inner ends of the vane slots, whereby the vanes d are forced outwardly; the entrained oil lubricates the vane slots and passes to other bearing surfaces. The near end of the wick has an inserted perforated sleeve h to maintain it extended and thereafter the wick passes through a compressing gland p, where it is bound with wire r, into a closed oil chamber n filled through a plug q. Specification 559,772 is referred to.

Abstract: 403,430. Projectile fuzes. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Magyar Fem-es Lampa-Aru Gyar Reszveny-Tarsasag; Budapest.) May 20, 1932, No. 14427. [Class 9 (i).] The firing-mechanism of a hand grenade is held at safe by means of a concavo-convex spring disc 4 with a bent edge 4a holding a disc 3 tightly against a washer 3a in a socket 2 on the grenade body 1, thereby confining a flap 7 pivoted at 6 and bearing over a head 9 carrying pins 10 which lock balls 12 against the edge of a sleeve 14 of one member 13 of a percussion fuze constituted by two members 11, 13 held against conical seats 18, 17 by a spring 19. The disc 4 is pressed in position by pressure on a ring 5. Before use, the disc is loosened by finger pressure on its centre and removed. Then when the grenade is thrown, the flap 7 swings out and the head 9 falls off with the pins 10, leaving the balls 12 free to move inwards. On impact, the fuze is fired by the approach of the members 11, 13 towards each other. A ring 20 supported by a spring 21 is provided for safety in case of a premature fall as described in Specification 403,675.

Title: Electro-optical displays
IPC: G02F1/1339
Filed: 1975-04-09
Abstract: 1487890 Controlling light RANK ORGANISATION Ltd 24 March 1976 [9 April 1975] 14545/75 Heading G2F [Also in Division G5] An electro-optical cell, e.g. for a nematic liquid crystal display, comprises two walls spaced by conducting or insulating spacing elements bonded to adhesive which can be softened, e.g. by heat, so as to seal the cell while the thickness of the spacing elements determines the spacing. If conducting elements 6 are formed on the inner face of one wall in the form of 7 bar displays as in Fig. 4, opposing a conducting film on the inner face of the other wall, the metallic spacer elements 3 may be bonded to a thermoplastic layer 4, e.g. by application to the layer as a printed circuit, to make contact where they are interrupted by window 5 with the conducting elements, while an additional element 3 (not shown) contacts the opposing conducting film. When layer 4 is softened by heat it seals the cell and allows elements 3 to set the spacing at their own thickness. Alternatively, if other means provide connection, the spacer may be a high melting point thermoplastic film coated, e.g. from a chloroform solution Fig. 6 (not shown) with lower melting point layers, so that the cell may be sealed by heating to soften these layers, Fig. 5 (not shown).

Each upright comprises a unitary structure having the same number of spigots extending from its upper and lower ends. The shelves have through holes 22 which receive the spigots. Adjacent shelves 21 are interconnected with each other by double uprights, each having a pair of spigots at the upper and a pair of spigots at the lower end thereof. Supports are provided for mounting the assembly on a kiln car, each support comprising a disc 23 with an upstanding spigot 24 which engage within a shelf hole 22. In a modified support assembly, the uprights 28, 29, Fig. 9, (in addition to having spigots which enter through-holes in the shelves 21) have supports 26, 27 for shelves 31 intermediate the shelves 21. Details of the uprights 10, 15, 28 and 29 are illustrated in Figs. 1 to 4, 6 and 7 (not shown). The upright 10 comprises a tube with a pin cemented therein. The pin ends form the spigots. The double upright 15 comprises two structures, similar to the uprights 10, held together by members (19) which are cemented in position. The support assembly may have muffles in the form of hinged doors fixed between the uprights to avoid the need to muffle the kiln.

Abstract: 609,014. Converting. SUBMARINE SIGNAL CO. (LONDON), Ltd., and BIRD, W. G. May 14, 1946, No. 14571. [Class 38 (ii)] [Also in Group XXXVIII] A voltage-doubling impulse generator for exciting a vibrator 10 in a submarine echo sounder (see Group XXXVIII), comprises condensers 7 and 8 which are connected in the circuit of the vibrator and through rectifiers 3 and 4 to an A.C. source such that on completing the circuit through the switch 11, a pulse discharge at twice the individual potentials of the condensers relative to earth is generated. The centre point of the winding of the vibrator is connected to earth; alternatively, if no centre tapping is provided, a pair of high resistances is connected in series across the winding and the junction connected to earth, Figs. 3 and 4 (not shown). As shown, a rotating cam 12 causes the periodic closing of the switch 11. In an alternative embodiment (Fig. 2, not shown) a periodically triggered gas discharge tube is used as the switch. Resistors 5, 6 and 17 are inserted in the circuit to reduce the current surges which occur during the discharge through the vibrator 10 and they may be omitted if the circuit is designed suitably. A safety switch 18 discharges the condensers when the lid of the apparatus is removed.
