Abstract: 1371598 Electric battery lamps UNION CARBIDE CORP 30 Aug 1973 [31 Aug 1972] 40851/73 Heading F4R A portable fluorescent lantern comprises a first casing 10 adapted to receive a fluorescent tube 13 and a second casing 11 adapted to contain one or more high-voltage batteries, the casings being detachably joined together so that the lantern can be operated with the casings either connected to form a single assembly or separated and disposed at spaced locations and the casings being electrically connected by a flexible cable (72). The first casing 10 incorporates a flexible reflector 14, which when bent and engaged resiliently behind shoulders 34, 35 at the sides of the front opening of the casing has a parabolic cross-section, and a transparent lens 12 which also engages behind the shoulders 34, 35, the sides 19, 20 of the casing being joined by strengthening ribs 25, 26, 27 which are parabolic in shape to support the reflector in its proper configuration. The rear of the casing is closed by a base 40 which is secured by screws 28 passing through apertures in the ribs 25, 27 and comprises top and bottom walls 42, 43 carrying the lamp holders 69, 70 and a back wall 41 carrying integral panels 47, 48, 49 which divide the base into four compartments. The upper compartment contains the switch (54) having switch buttons 57 58, 59, together with a resistor (61) and a capacitor (65), the left-centre compartment (51) contains a ballast transformer (68), and the right-centre compartment contains the flexible cable (72) when the casings are joined together. The second casing 11 has an integral back wall 80 and is closed at the front by an insert 89, which carries a sliding latch 122 for joining the two casings, and a removable battery cover 98. The insert also carries a receptacle (115), to receive the prongs on a plug (73) at the end of the cable (72), and a partition wall 92 which supports metal leaf springs, for making electrical engagement with the battery terminals, and a stabilizing resistor (119). The impedance of the ballast transformer (68) matches the value of the resistance (119) so that the lantern may if desired be connected directly to an A.C. mains supply. The circuit components mounted in the first casing may alternatively be installed in the second casing.

Abstract: 1321853 Hydrogen absorbing in cells UNION CARBIDE CORP 26 Aug 1970 [27 Aug 1969] 40964/70 Heading H1B A self-supporting hydrogen absorbing body is formed by a solid compound consisting of a material which reacts chemically with hydrogen gas, a catalyst for the hydrogen gas reaction, and a binder. The body is encased within a gas permeable but liquid impermeable, sheath. In a preferred composition for the body the chemical reactant is powdered electrolytic manganese dioxide, the catalyst is palladium-catalysed carbon and the binder is a mixture of Portland cement, actylene black and steel wool fibres, the reactant and catalyst being intimately mixed and dispersed through the binder. These mixed constituents in the form of a paste are applied to a mould and dried in an oven to obtain self-supporting hydrogen absorbing pellets of a desired shape. The outer sheath may be of polyethylene film. Alternative reactants are manganic oxide, manganese hydroxide and housmannite, cupric oxide, silver oxide, mercuric oxide, manganese phosphate, bismuth trioxide, m-dinitrobenzene, and quinone. Alternative catalysts are platinum, rhodium, nickel boride, and Raney nickel. Alternative binders are polyethylene, and starch. Low density carbon powder may be included in the pellet mixture so that the pellet may float on the electrolyte of an electrochemical cell. Fig. 1 shows a re-chargeable manganese dioxide-zinc alkaline battery incorporating a hydrogen absorbing pellet 34, having an outer sheath 36, situated within a tubular current collector 14 fixed by a rivet 42. The rivet is insulated from an inner metal bottom 38 by a seal 40 but the rivet head makes electrical contact with outer metal bottom 28 through a spring 44. A separator basket 32 of a non- woven fabric of regenerated cellulose and vinyl chloride is between a gelled anode 12 of powdered zinc and a cathode 16 of manganese dioxide. A potassium hydroxide electrolyte 18 is contained within the current collector 14 and throughout the anode 12. A metal jacket 22 insulated by a jacket 24 from the external metal can 20, is connected to a metal cover 26. A Leblanche battery, Fig. 2, includes a ring shaped hydrogen absorbing body 68 situated above the manganese dioxide-carbon depolarizer mix 54 surrounding the carbon cathode rod 52. The mix 54 is spaced from zinc can 56 by a separator 58, the can being enclosed in a plastic jacket 62. A plastic top 64 is capped with a metal terminal 66 and a lead-plated steel member 60 seals the bottom.

Abstract: 1,247,074. Loom gear transmission mechanism. TSUDAKOMA INDUSTRIAL CO. Ltd. 18 Aug., 1969 [7 Sept., 1968], No. 41126/ 69. Heading D1E. A loom gear transmission mechanism comprises an eccentric circular gear 13 on a main shaft 12 meshing with an eccentric circular gear 8 on a crankshaft 1 on which an eccentrically mounted gear 9 meshes with an elliptical gear 11 on a tappet shaft 2. The gears 13, 8, have the same peripheral length while gear 9 has half the peripheral length of gear 11 and the phase relationship is such that during shuttle travel the teeth on gear 13 nearest shaft 12 mesh with these on gear 8 furthest from shaft 1 whilst during picking motion the teeth on gear 9 furtherest from shaft 1 mesh with the teeth on gear 11 nearest shaft 2. The offset of this is that picking motion is carried out when the angular velocity of the crank shaft, and hence the velocity of the slay, is at its lowest whilst that of the tappet shaft and hence the acceleration of the shuttle is at its highest.

Abstract: 1,181,310. Separating krypton and xenon. LEUNA-WERKE WALTER ULBRICHT. 8 Sept., 1967, No. 41156/67. Heading B1L. A mixture of 55% Kr, 5% Xe and 45% N 2 , O z  and A in gasholder 17 is drawn by compressor 5 through valve 3 into line 4 and thence to activated carbon adsorption column 7. Before breakthrough, this gas flow is stopped by switching valve 3 to allow only H 2  as carrier gas, to flow from gasholder 1 along lines 2 and 4 to column 7. As the H 2  passes through column 7 the N 2 , O 2  and A are entrained first through line 8, valve 9 and line 20 to liquid N 2  trap 23 where they are liquefied; the H 2  carrier passes on through heat exchanger 22 and line 24, back to gasholder 1. When first Kr and then Xe emerges in the carrier gas from column 7, they are detected by thermal conductivity cell 19. The Kr fraction is passed by line 10, valve 11 and line 12 to freeze trap 14. The Xe fraction is driven off from column 7 by heating to 70‹C., and is conveyed by line 10, valve 11 and line 25 to freeze trap 27. The effluent H 2  carrier gas from traps 14 and 27 are returned to gasholder 1 by line 16. The Kr and Xe fractions are subsequently removed by lines 44 and 45 respectively.
