Title: Improvements in or relating to Electrochemical Cells
IPC: D03D49/52
Filed: 1966-12-13
Abstract: 1,176,487. Metal/air batteries having apertured intercell spacers. LEESONA CORP. 13 Dec., 1966 [30 Dec., 1965], No. 55795/66. Heading H1B. A battery comprises a plurality of metal-air or metal-oxygen cells, each containing an envelope cathode comprising a hydrophobic polymer membrane, coated on the inner surface with a catalytic layer, surrounding a metal anode and separated therefrom by an electrolyte layer, and spacers between adjacent cells having openings therein to permit access of air or oxygen to said cathodes, and end plates at each end of said plurality of cells, and means for retaining said cells, spacers and end plates in operable association. The cells are preferably those described in Specification 1,176,486. Suitable spacers are described, e.g. in Figs. 8c, 9 and 10. The units may be held together, e.g. by a U-shaped clamp having an adjustable bar across its mouth, or by cam-type clamps operating upon the end-plates in association with a battery casing having openings therein permitting access of air or oxygen, which openings may be opened and closed by apertured slides. This last feature, whereby the air supply is controlled, is the subject of Specification 1,176,488, divided from the present one.

Title: Sprung self levelling pick up hitch
IPC: B62D53/06
Filed: 1972-12-11
Abstract: 1370363 Spring pick-up hitch W S H TAYLOR ENG DEVELOPMENTS Ltd 11 Dec 1972 [3 Dec 1971] 56114/71 Heading A1P An arrangement for the attachment of a hitch to a towing vehicle, is characterised in that the height of the hook is self-adjusting to suit the height of the connection to the trailer, both statically and when moving over irregular ground, at the same time providing a substantially constant vertical force at the connection. A frame 11 is rigidly attached at its rear end to the vehicle rear axle 16 by cross member 11d and two vertical members 11e and pivotably attached to cross member 10 by pin 10a. Supported by two side arms 11a, of the frame is a cylinder unit 13 which has a first piston 13e coupled to a transverse leaf spring 14, the ends of which are carried by cross member 11d. The second piston 13e is connected to a U member 12j, comprising cross piece 12j" and two side arms 12j'. The swinging arm 12a carrying the hitch 12b is connected to the U member by levers 12h and connecting arms 12i. The cylinders 21 and 22 are connected hydraulically by port 130 and are initially pressurised by a pump driven by the vehicle and feeding oil through port 13n from an external connection (not shown) causing piston 13d to move the swinging arm upwards until the hitch connects with the trailer eye and piston 13e to apply an equivalent load to the transverse spring 14. Over uneven ground, downward movement of the trailer causes piston 13a to move inwards forcing oil past the non-return valve 131 so that piston 13e moves outwards against the transverse spring. Upward movement of the trailer causes reverse flow through port 130. As the hitch approaches its upper limit, the pressurised oil in cavity 21 is allowed to escape into chamber 19 via ports 13i, 13j and tapered channel 18a. At the same time springs (not shown) in recess 13g provide a buffer action. The air partly occupying chamber 19 limits the oil pressure within the varying volume of the connected cylinder. During towing, the vertical movements of the hitch cause oscillation of the cylinders and the varying annular volume 23f around the piston 13e acts as a pump to transfer oil from chamber 19 via conduit 23e and non-return valve 23c into cylinder 22 past non-return valve 23d. Mechanical transmission may be used rather than hydraulic. Also a damper may be added between the swinging arm and the vehicle chassis.

Abstract: 1332929 Measuring electrical power and power factor BROWN BOVERI & CO Ltd 8 Dec 1970 [10 Dec 1969] 58191/70 Headings G1A and G1U To measure the power carried by a high voltage A.C. line 18, a monochromatic polarized light beam 6 is passed through both an electrooptic element 7 responsive to the line voltage and a magneto-optic element 11 located in the magnetic field of the line, and is then split (13) into two parts having perpendicular directions of polarization. The two parts are detected by separate photo-detectors 16, 17, the difference in the detector currents being proportional to the instantaneous power. Signals representative of the current and voltage may also be produced and passed, with the detector outputs, to a computing circuit for evaluating the power factor directly. In Fig.3, light from a laser 1 is passed through a polarizer 3 to a linear quarter-wave plate 5 of mica, providing a light beam 6 of circular polarization. The electro-optic element 7 may be disposed in the electric field of the line 18 or may be coupled to the line by a capacitive potential divider Fig.2 (not shown), and is constituted by a Kerr cell or by a Pockels cell comprising LiNbO 3  or a crystal of potassium di-hydrogen phosphate or a ferro-electrical perovskite. The light beam 8 is then passed through a circular quarter-wave plate 9 of quartz to a Faraday rotor 11 disposed in the magnetic field of the line and comprising flint glass or an yttrium-iron garnet crystal. The light beam now comprises an ellipticallypolarized beam, the eccentricity of the polarization having being determined by the electrooptic element 7 and its inclination by the magnetooptic element 11. The beam is split in a Wollaston prism or Banning polarizing beam splitter 13, and the two beams passed to respective germanium photo-diodes 16, 17. Flexible optical fibres 20-22 are used to convey the beam where necessary.
