Title: Covers for cells or batteries
IPC: H01M50/147
Filed: 1976-11-08
Abstract: 1501059 Cell or battery covers GOULD Inc 8 Nov 1976 [17 Nov 1975] 46348/76 Heading H1B A cover for a case of an electric storage battery or cell comprises an inner surface engageable with portions of the case for closing the cell or battery, a fill and vent opening extending therethrough, and a rib on its inner surface for directing liquid to the opening when the cell or battery is inverted and rocked from side to side. In one embodiment, an inverted battery 10 from which liquid is being drained comprises a cover 12, the inner surface of which is shown in Fig. 2, and includes a shallow peripheral groove 21 in which the side walls of the case fit with the upstanding flange 22 overlapping the side walls of the case. The recess or channel 16 (Fig. 1) in which the vent holes 13 are located is formed by two raised step-like shoulders 25 and 26; the holes also include integral collars 27 and extensions 28 which project into battery case 11. A plurality of integral guide upstanding vanes or ribs 31 concentrate and direct liquid over the step 25 and into the collar 27 and then into vent hole 13. The vanes may extend completely to the wall 12 of the cover (Fig. 2, middle cell compartment) or they may stop short of the wall (outer cell compartments). As shown in the lowest cell compartment (Fig. 2) an integral guide vane 35 concentrates and directs the reverse flow of liquid over step 26 and around 28 during the rocking cycle. Alternatively, a single rib 37 (Figs. 6-8, not shown) may be integrally formed in the front portion of the cell area extending from the front edge of 12 to collar 27. In another embodiment the concentrating means (Figs. 11 and 12, not shown) include a series of three integrally formed ribs 40, 41 and 42 defining progressively smaller channels 43 and 44 leading to vent hole 13. The battery case and cover may be of hard rubber or thin wall plastic material (e.g. polypropylene or ethylene-propylene copolymers); and the battery is preferably of a lead-acid secondary type.

Title: Production of aluminium from aluminium chloride
IPC: C22B21/00
Filed: 1973-10-16
Abstract: 1419450 Producing Al from AlCl 3  TOTH ALUMINUM CORP 16 Oct 1973 [16 Oct 1972] 48120/73 Heading C7D Aluminium is produced by reacting liquid or gaseous aluminium chloride with solid, preferably powdered, manganese at temperatures and pressures at which the reactants maintain their respective phases, the preferred range being 180 to 600C 1 to 30 atmospheres. Although aluminium metal is normally separated from the product it is possible to produce an Mn-Al alloy ingot by this method. The reactions may be carried out with the AlCl 3  in gaseous form by passing the gas through a bed of Mn particles, Fig. (not shown); if the AlCl 3  is liquid it is added to a charge of Mn particles, Fig.2 (not shown), the process being adapted for batch operation Fig.3 (not shown) or continuous operation, Fig.4 (not shown). Inert metal salts, e.g. NaCl, CaCl 2 , KCI, MgCl 2  or BaCl 2  may be added to lower the vapour pressure of the AlCl 3 .

Title: Photo-responsive detectors
IPC: G08B17/103
Filed: 1975-11-26
Abstract: 1529473 Smoke detectors CHLORIDE BATTERIJEN BV 26 Nov 1975 [27 Nov 1974 9 Oct 1975] 48613/75 Heading G1A A detector Fig. 2 comprises: first and second photo-resistive cells C1, C3 placed to receive light originating at a source 18, the first cell C1 only after reflection by a test medium; means R1, A1 responsive to a decrease in resistance of C1 to a predetermined resistance to actuate, SCR, a signalling device A; and control means R2, A2, T1 responsive to a change in the resistance of C3 to adjust the source 18 to an intensity at which C3 is continuously exposed to that intensity which causes its thermal resistance coefficient to be substantially equal to that of Cl when exposed to the light intensity at which its resistance is equal to the predetermined value. In a smoke detector Fig. 1 a block 10 houses a LED 18 directing a beam via a lens 20 through a first aperture 12, and a first photo-resistive cell C1 viewing, via a lens 22 and aperture 14, light forward-scattered by any smoke in the beam. A second photo-resistive cell C3 in the block 10 receives, via a light guide 24, light in the beam path which may have been attenuated by the smoke. A manual screw 26 regulates the amount of light received by C3. A further photosensor C2 monitors the source 18 to actuate a warning lamp L, Fig. 2 in case of failure. The cells C1, C3, Fig. 2, having matched characteristics and temperature coefficients, are connected in series with respective equal resistances R1, R2, the junction points Jl, J2 each being connected to an amplifier A1, A2 arranged to change its output state when its input crosses a potential equal to half the supply voltage. The first amplifier A1 is connected to trigger a SCR actuating an audible warning device A. The second amplifier A2 controls the LED 18 so that the light received by C3 is just sufficient to maintain its resistance equal to R2 and therefore equal to the resistance which Cl will have at the alarm point. The arrangement is especially advantageous in maintaining the sensitivity and accuracy of the detector in the presence of black smoke having high attenuation and poor reflectivity.

Abstract: 1,269,150. Coating with metals. BRITISH STEEL CORP. Sept. 21, 1970 [Oct. 9, 1969], No.49614/69. Heading C7F. The spot-welding characteristics of a ferrous substrate are improved by hot-dip coating it and directing particles of metallic iron or iron-based alloy on to the coating before it solidifies, so that they are retained at or near the surface of the coating during solidification. The substrate may be a ferrous strip, e.g. of low alloy steel containing Cu and Cr, subjected to a grease burn at about 400 C., subjected to a reducing atmosphere at about 700 C., and then continuously moved through the hot-dip bath, excess molten coating being removed by a pair of rolls or a controlled air-blast. The coating metal may be zinc, aluminium, or an alloy thereof, e.g. Zn-Al, Al-Mg, or Al-Si. The said particles preferably are -200 mesh, and arrive at the strip at no more than 500 ft/min., preferably 300-500 ft/min., in an amount of 1-3 g/sq.ft., and for heavy gauge, e.g. > 0À048 inch, strip, a second supply of particles may also be used, at higher velocity and in lower quantity than the first, e.g. at 500- 1000 ft. /min. and 0À1 to 0À2 g/sq.ft. The particles may be Fe, mild steel, or 80Fe-20Zn. The coated product may be coated overall with a layer of iron, either electrolytically, or preferably, by immersion plating in a FeCl 2  solution containing 56 g/l Fe at pH 2À2 and 40C. for 5 seconds.

An apparatus comprising two cylinders 1 and 2 in which the seals between pistons 3 and 4 and the cylinders 1 and 2 are formed by rolling diaphragms 9 and 10 respectively, has annular spaces 11 and 12 each filled with liquid under the diaphragms respectively, a supply duct 13 for the liquid connected to the space 11 and a control device 16 which maintains a constant pressure difference across each rolling diaphragm. The spaces 11 and 12 communicate with one another through a duct 14 and the pressure control device 16 allows liquid to flow away from the apparatus to maintain the constant pressure difference across the diaphragms as the pistons vary the volumes of the working spaces 7 and 8.

Abstract: 505,715. Fluid-pressure servomotorcontrol systems. CERINI, L. April 23, 1938, No. 12238. Convention date, April 24, 1937. [Class 135] [Also in Group XX] The gyroscope 1 is caused to process into alignment with a disc 12, repeating the in indications ofa magnetic compass, by differentially controlled air nozzles 13 oppositely directed onto a series of vanes 14 carried by the rotor bearing ring 3. The supply of air to the nozzles 13 is controlled by a valve 10 operated by differential air pressure created by the variable obturation by the disc 12 of a vent pipe 11 leading from the valve 10 and carried by the vertical ring 5. As shown in Fig. 3, the valve 10 comprises a double-headed piston moving in a cylinder provided with an aperture 17 at one end and connected to the vent pipe 11 at the other. Air is supplied to the cylinder through a central pipe 9 and may leak through holes 15, 16 in the piston. Changes in the degree of obturation of the pipe 11 cause the piston to move and allow the air to pass to one or other of the nozzles 13. The spin axis is maintained perpendicular to the vertical ring 5 by a radial air jet 19 co-operating with a pair of oppositely inclined blades 18 on the ring 3 to provide a torque about the vertical axis 6, 7 when spin axis deviates.
