A fuel cell comprises an electrolyte-retaining matrix which consists of an electrically conductive layer (3a) in face-to-face contact with an electrically non-conductive layer (3b), a thin electrode (2 and 6) in contact with each of the two outer faces of said matrix, and means (7 and 8) for supplying reactant to a surface of each of said electrodes. A conductive layer (5) may be placed between the non-conductive matrix layer and the adjacent electrode. The drawing, to which the above references relate, represents an embodiment of the invention. The conductive matrix layer may be of, e.g. Ni, Cu, Ta, Au, Ag, Pd, Pt or Rh; the non-conductive layer may be e.g. an oxide of Ce, Th, Si, Zr or Mg and may be applied to the conductive layer by flame spraying, electrophoresis or sintering. The electrodes may be a mixture of an electrochemically active metal, e.g. Cu, Ag, Au, Co, Ni, Pt, Ru, Pd, Os, Ir and Rh, and a hydrophobic polymer, e.g. P.T.F.E., polystyrene, polyethylene, polyvinylfluoride, polyvinylidenefluoride and polytrifluorochloroethylene, applied directly to the surfaces of the matrix by pressing, rolling or spraying a dispersion, and heated to sinter the polymer; where H 2  is the fuel a Pd/Ag alloy membrane anode may be used. The optional conductive layer (5) may be a thin film coating of e.g. Au, Ni or Ag, or a screen, expanded metal, felt or mesh of e.g. Ni, Ta, Cu, Au, Ag, Pd, Pt and Rh, pressed into contact with the catalytic layer. Suitable electrolytes include the hydroxides and carbonates of Na, K, Rb and Cs, and H 3 PO 4  and H 2 SO 4 . Suitable fuels include H 2 , hydrocarbons and ammonia. In an example a porous Ni sheet is flamesprayed with cerium oxide; a layer of gold is electrodeposited on the cerium oxide layer, and the nickel and gold faces are then sprayed with an aqueous dispersion of P.T.F.E. and Pt black. The structure is used in a cell fed with H 2  and O 2  using 28% aqueous KOH as electrolyte.

Abstract: 1,017,073. Stranding wires. STEEL CORDS Ltd. Dec. 7, 1962 [Dec. 8, 1961J, No. 43973/61. Heading D1T. A method of manufacture of a metallic strand from a number of individual wires between two and six comprises winding the wires simultaneously as a group with winding twist by winding them overend on to a single bobbin and then leading the group from the wound bobbin through a twisting device to a take-up device. As shown the wires 3 are unwound from a stationary bobbin 1 by a flyer 5 that removes said winding twist so that the wires passing over the pulleys 6 are parallel and untwisted. The desired twist is put into the wires 3 by the rotation of the spindle 2 and the disc 9. From the take-off device 4 the twisted group of wires, now forming a strand pass through a false twist unit 11 that rotates about the axis of the approaching strand to increase the amount of twist already applied to the strand in a manner straining the wires. The strained strand then passes through a straightening device 12 that also arrestes rotation of the strand imported to it by the false twist unit, so removing the additional twist applied to the strand and allowing the strained wires to relax to set them with the degree of twist applied by the rotation of the spindle 2. The strand passes through the usual traverse device 13, details of which are not given, to a takeup reel 14 which is mounted with its axis perpendicular to the approaching strand so that no winding twist is applied. The positions of the torsioning unit 11 and the take-off device 4 may be reversed, the take-off device 4 then serving to arrest rotation of the strand on it emerges from the false twist unit 11.

Abstract: 991,911. Water tube steam boilers; super-heaters. FOSTER WHEELER Ltd. Dec. 11, 1962 [Dec. 11, 1961], No. 44241/61. Heading F4A. A steam generator comprises an upright cylindrical shell 10 through which heating fluid e.g. the coolant from a nuclear reactor, circulates, the shell containing a coaxial downcomer 16 leading from a steam and water drum 18 which surmounts the shell 10. Steam generating riser tubes are distributed across the space within the shell, each riser tube consisting of an inlet tube 20, an outlet tube 22 and a cluster of tubes 24 therebetween attached to circular or polygonal headers. The headers are preferably hexagonal with nineteen tubes to a cluster, the hexagonal shape contributing to uniform distribution of the tubes across the shell. The inlet tubes 20 are attached to the lower end of the downcomer while the outlet tubes 22 discharge into an annular collecting riser 26 which surrounds the downcomer, passes through the upper end of the shell and thus leads the steam and water mixture into the steam and water drum 18. The latter contains steam separating and drying means 38, 40 and has a baffle 46 which defines with the shell of the drum and passageway 48 for dried steam leading to a further annular passageway 50 formed within the collecting riser 26. Superheating tubes 44 which are of similar form to and surround the steam generating tubes, receive steam from the passage 50 and deliver to an extension 54 of the lower end of the downcomer forming a final steam outlet. The latter passes freely through the lower end of the shell, a bellows 58 making the necessary seal. To ensure uniform distribution of the tubes across the shell the individual tubes may be sprung apart by taper keys 62 inserted in spacer plates 60, Fig. 4, as described in detail in Specification 991,915, and the headers may be staggered slightly in the vertical direction to allow for easy throughflow of the heating medium. Specifications 991,912 and 991,913 also are referred to.

Title: Improvements in displacing apparatus

Filed: 1964-11-03
Abstract: 1,063,170. Driving record tapes. PHOTOCIRCUITS CORPORATION. Nov. 3, 1964 [Nov. 5, 1963], No. 44701/64. Heading G5R. [Also in Division G3] Pulses to be recorded on magnetic tape 13 are transmitted through channels 20, 21, 22, to head 14, the input pulses also being transmitted to flip-flop generator 15 which produces a positive output pulse for comparison with the rising voltage developed by tachometer generator 17 driven by capstan motor 10 of the printed circuit-type. A saturable amplifier 19 amplifies the error signal so that the motor is accelerated to a terminal velocity determined by the voltage level supplied from the generator 15. While the tape is stationary and just beginning to accelerate, the input pulse is recorded on the tape and, shortly after the motor has reached its terminal velocity, a pick-off head 32 develops an output pulse from pre-recorded spaced signals on disc 31. This pulse is amplified by amplifier 33 and applied as a stop-pulse through amplifier 38 to generator 15 which resets to zero output. The motor then decelerates to zero speed, causing a further tape displacement. A switch 45 is closed to generate a record gap, a one-shot pulse generator 46 developing a positive output pulse which is applied in series-opposition with tachometer generator 17 to advance the motor. During this period, however, a negative pulse from generator 48 is applied to amplifier 38 to prevent the pulses from pick-off head 32 from being passed through the amplifier 38. The pulse from the generator 46 causes the motor to accelerate and to operate at constant speed until the pulse is terminated. The generator 48 returns to its initial condition after the pulse from the generator 46 is terminated, to allow the motor to decelerate to its normal speed at the termination of the gap. The next pulse from the head 32 stops the motor so that its registration is correct. The tape is read a line at a time by means of pulse generator 77 whereby the motor is accelerated to its terminal velocity until the head 14 reads the next line of pulses. A stopsignal is then applied through amplifiers 71, 72, 73, to amplifier 38 and generator 15 to decelerate the motor. Closure of switch 40 causes the motor to run continuously. The apparatus may also be operated at high speed in a line-byline manner without coming to a stop during either the recording or reading operations except after the recording or reading of the final line of data.

Dec. 30,1960 [March 10, 1960], No. 44724/60. Heading G2A. Automatic camera diaphragm control means comprise an exposure meter which is rotatable according to the setting of the shutter speed and the position of an abutment surface on a detachable objective which is indicative of the maximum aperture thereof. On depression of the camera release 22, a lever 18 clamps the meter pointer 8 and a lever 128 releases the setting mechanism which runs down until an arm 86 is arrested by pointer 8. Arm 106 moves around the lens axis allowing the diaphragm ring 62 to be adjusted by a spring 68. A push rod 42 operated by a cam 46 on the shutter speed ring rotates the meter relative to a scale 83 through the gear train 26. When an objective with a different maximum aperture is fitted an abutment thereon shifts a push rod 44 to rotate the meter in a similar fashion. In this case scale 83 is similarly rotated through a linkage 76, 78, 80, 82 so that pointer 8 remains registered with the same division of scale 83 and the maximum aperture of the new objective is in the first sensing position of arm 86. Film speed is allowed for by setting a scale 52, causing cam 46 to rotate the meter accordingly. In a position for manual setting, a cam 142 disengages a clutch 108, 110. Specifications 275, 462 and 778, 933 are referred to.
