The area of the openings should be in the range 78-65,000 square microns. The cell shown has an anode 3, a separator 5 impregnated with electrolyte, a cathode 7 of depolarizer mix, and a frame of adhesive sealing material 15. The seal may be dispensed with (Fig. 4, not shown) and the impregnated separator may be replaced by layers (45, 49) of immobilized electrolyte on either side of a separator (47). The cells may be combined to form a battery; a "duplex electrode" comprising a cathode, a porous anode 42, Fig. 3 (not shown) of powdered Zn and a gas permeable conductive layer (40) may be used.  The cathode collector may be porous conductive substrates, e.g. compressed metal wools or sintered metals; or it may be made of steel, Cu, Zn, Ni, Ni alloys or graphite.  The conductive layer may be a solution of a copolymer of vinyl chloride and vinyl acetate in an organic solvent containing a suitable stabilizer (e.g. epoxy resin) for high temperature conditions and a plasticizer for flexibility. An electrically conductive particulate material (e.g. acetylene black and/or graphite) may be added. The adhesive used for the frame 15 may have similar compositions, e.g. vinyl adhesives or hot melt adhesives of vinyl-wax mixtures. Suitable anodes for the cell are Zn (sheet or powdered), Zn-clad steel, Al, Pb, Cd and Fe. Suitable cathodes are MnO 2 , PbO 2 , HgO, silver oxide, nickel oxyhydroxide, inorganic metal halides (e.g. of Ag and Pb) and organic materials capable of being reduced, e.g. dinitrobenzene and azodicarbonamide compounds. The electrolyte may be ZnCl and/or NH 4 Cl, KOH, NaOH, LiOH, acidic electrolytes, e.g. H 2 SO 4 , H 3 PO 4 , and non-aqueous electrolytes. The electrolyte may be liquid or gelled and may also be a viscous or "tacky" mass which can be held within the bounds of the cell by a suitable electrolyte-impermeable coating around the sides thereof, thus additionally serving to hold the cell components together. Other suitable aqueous electrolyte systems are Ni-Zn, Ag-Zn, Hg-Zn, Hg-Cd and Ni-Cd. The separators may be made from fibrous and cellulosic materials or woven or non-woven fibrous materials such as polyester, nylon, polyethylene and glass.

Title: Improvements in circuit arrangements comprising image converter tubes
Inventor: PERILHOU JEAN ROBERT
IPC: H01J31/50
Filed: 1955-10-17
Abstract: 943,320. Cathode-ray tubes. LABORATORIES D'ELECTRONIQUE ET DE PHYSIQUE APPLIQUEES. Oct. 17, 1955, No. 29605/55. Heading H1D. A circuit arrangement comprises a tube for converting infra-red images into visible images comprising a control electrode, a focusing system, a fluorescent screen, an input screen embodying a semi-transparent layer through which the infra-red images are projected, and a photo-emissive layer, wherein the input screen includes, between the semi-transparent layer and the photo-emissive layer, a semi-conductive layer having photo-conductive properties in relation to infra-red radiation, the circuit including means for periodically cutting-off the flow of electrons between the input screen and the fluorescent screen. The tube shown in Fig. 1 has a target comprising a layer 3 of conductive and semi-transparent material (e.g. a thin layer of silver or aluminium), a photoconductive layer 4 (e.g. lead sulphide), and a photo-emissive layer 5 having a mosaic structure, a conductive layer opaque to light, e.g. of graphite, may be provided between the layers 4 and 5. The tube also includes a finemesh grid 6 parallel to the target, a fluorescent screen 8, and a focusing coil 9. The layer 5 is uniformly illuminated from a source 7 of preferably monochromatic radiation, either visible or invisible. In one method of operation the grid 6 is biased negatively and positive pulses are applied to it ; when the layer 4 has its maximum resistance the layer 5 is unable to charge up during the pulses to the point where electrons emitted from it are able to penetrate the grid 6, but when the layer 4 has a reduced resistance due to the incidence of infra-red radiation the time constant is reduced and emitted electrons reach the screen 8. A similar effect can be obtained by biasing the grid 6 negative and pulsing the light source 7. The recurrence frequency of the pulses should exceed the flicker rate and may be about 50 per second.

Title: Improvements relating to scrap shearing machines
IPC: B30B9/32
Filed: 1956-09-28
Abstract: 797,181. Consolidating and shearing metal scrap. LINDEMANN, W. Sept. 28, 1956 [March 19, 1956], No. 29739/56. Class 83 (4). In a scrap shearing machine the scrap is compressed by plungers having separate drives so that each plunger compresses the scrap to an extend dependent on the resistance of the scrap beneath it. The scrap is fed from a tipping bucket 13 into a trough 10 along which it is pushed step-by-step by an hydraulic ram 11. The plungers 22 ... 25 in the form of rectangular cylinders slidable on pistons 28 are at each stroke of the machine lowered under their own weight on to the scrap and then hydraulically forced to compress the scrap. A guard 75 protects the plungers when inoperative. The consolidated scrap is cut into blocks by a moving blade 18, shaped as shown in Fig. 4, and a fixed blade 16, the bed 39 adjacent the fixed blade being grooved to prevent lateral movement of the scrap, The moving blade carrier 17 has extended guides 117 sliding in slideways 19 and forming a flush surface with the frame so as to provide a smooth throat. The blade carrier 17 is additionally guided by a sliding member 122 and is mounted on two pairs of hydraulic rams 141 and 147. The blade is allowed to fall under its own weight and is then forced through the scrap by hydraulic pressure in rams 141. The opposing hydraulic pressure in rams 147 prevents undue acceleration of the blade as the cut is completed. The cut blocks may be fed by a reversible conveyer 34 to an oscillating slide 36 feeding the blocks to a shears 37 positioned at right angles to the main shears. The starting position of the strokes of the blade 18 and plungers 22 ... 25 may be varied.
