Patent GB-1159764-A (GB)
Title: Fuel Cells and Electrodes therefor.
IPC: H01M4/38
Filed: 1967-08-10
Abstract: 1,159,764. Rechargeable fuel cell. GENERAL MOTORS CORP. 10 Aug., 1967 [7 Nov., 1966], No. 36790/67. Heading H1B. A fuel cell comprises an electrode assembly in which: a reservoir holds a liquid reactant and an electrolyte electrolytically dissociable into the liquid reactant and a gaseous reactant; an electrically conductive penetrable element in a wall of the reservoir and in contact with the cell electrolyte provides communication between the inside and outside of the reservoir; a path admits electrolyte to the reservoir during discharge, so permitting the liquid reactant to remain in contact with the penetrable element; an electrically conducting conduit extends from below the electrolyte level in the reservoir to a point above the cell electrolyte and forms an " air-lift " type pump during recharging, so maintaining a pressure drop across the penetrable element towards the reservoir interior, the conduit being insulated from the reservoir and connected electrically to the electrode generating the gaseous reactant during recharge. In the Li/LiCl/Cl 2  cell illustrated the cell container 1 is of carbon lined with ceramic 16 in a stainless steel casing 2; during discharge Cl 2  is supplied to the annular electrode 11 and Li floats in the molten LiCl against the penetrable element 5 which defines with a stainless steel casing the reservoir 3 which is electrically connected to the outer casing 2; as Li is consumed LiCl enters the reservoir through element 5 or via a capillary. The carbon tube 4 is insulated from the reservoir and cell electrolyte by a ceramic layer 9 and lined with a ceramic layer 6 which is wet by LiCl; during discharge Cl 2  is generated at the exposed base of tube 4 which is connected to the chlorine electrode via carbon container 1 and forms a " gas-lift " pump; the pressure differential across element 5 ensures that Li there formed is retained inside the reservoir. Reference has been directed by the Comptroller to Specification 1,123,133.

Title: Improvements in water craft having hydrofoils
IPC: B63B1/24
Filed: 1960-10-26
Abstract: 946,465. Hydrofoil vessels. G. PIAZZA. Oct. 26, 1960 [Nov. 16, 1959], No. 36825/60. Heading B7A. An hydrofoil 10 (Fig. 5) is secured to one arm 2 of a lever pivoted at 4 so that the lift acts behind the pivot. The lift is balanced by a spring 7 at the end of the other arm of the lever, with the result that, if the lift increases, the incidence of the hydrofoil is reduced, or, if the lift decreases, the incidence is increased. The hydrofoil may be inclined upwardly, outwardly and forwardly as in Fig. 8, so that as the depth of immersion increases, and the waterline rises from N-N to A-A the centre of lift changes from n to a and the moment arm of the lift is reduced from x to z. Conversely, as the water line falls, the moment arm is increased. Hydrofoil units in the same transverse plane on opposite sides of the craft may be connected together. A water craft may be supported by two or more pairs of hydrfoils (see Figs. 9-12, not shown).

Abstract: 1317757 Centrifugal pumps WORTHINGTON CORP 30 July 1970 [31 July 1969] 36892/70 Heading F1C A single-inlet centrifugal pump of the type in which change of direction is imparted to fluid before it reaches the impeller comprises means adapted to effect a distribution of streams of sucked fluid along a substantially circumferential or spiral path with respect to the impeller axis, to effect a uniform inward deviation of the streams radially towards the axis and subsequently gradually and continuously to withdraw the fluid streams and convey them to the impeller in the direction of the axis in such manner that tangential velocity components are removed and a substantially uniform distribution of the axial velocity of the streams is effected. Liquid enters the pump via a volute 10 having a tangential inlet (not shown), the cross-sectional area of the volute being reduced progressively in the direction of rotation of the liquid about the volute axis by means of a reduction of either the radial depth of the volute or, as shown, the axial dimension. The liquid is progressively withdrawn from the volute through at least one row of blading 14 which produces a radially inward and axial deflection. As shown, the impeller (not shown) may be preceded by an inducer rotor 21. A chamber 15, exhausted via a port 17, may be provided for collecting gas and vapour from the liquid via an annular gap 16 between two castings 18, 19.

Abstract: 1,009,700. Tying bag necks. FMC CORPORATION. Sept. 25, 1963 [Oct. 5, 1962], No. 37643/63. Heading B8C. [Also in Division B3] After the neck 20a (Fig. 2) of a bag has been gathered against a stop 68, a tie 100 is applied to the neck by movement in the same direction as the bag to overtake it. In the form illustrated the tie 100 is carried by a double-armed lever 70 which also carries notches 68 forming the stop. When a mechanical sensing device indicates that the package 20e has reached the position where the bag neck is fully gathered, the arm 70 is rotated through half a revolution to apply the tie 100 : immediately before this a spring-biased stop 96 is positioned against the gathered bag neck. The package is carried on an endless belt (not shown) and the neck is flattened and fed firstly by guides 54 and subsequently by rollers 50, 52 whose peripheral speed is the same as that of the belt. One of the rollers may be grooved to fit into the other, which may be surfaced with a friction material. The tie is subsequently twisted by jaws 110 (see Division B3) which advance towards the tie, grip it and twist it, release it, and are then retracted and rotated in the opposite direction. Each tie may consist of a wire 194 (Fig. 13) sealed between two strips 196, 198 of paper. The ties are fed from stock 192 (Fig. 2) by rollers 202, 204, to lie across the notch 102 in the lever 70. The tie is then cut from the stock by a guillotine 244 and immediately afterwards is pressed into the notch 102 by a shaping finger 262. The devices for feeding the tie stock, and for applying and twisting it, together with the equipment for gathering the bag neck, may be formed as a unit separate from the conveyer carrying the filled bags, and the unit may be pivoted to permit its use in conjunction with a laterally inclined conveyer.
