Abstract: 1,214,359. Fuel cell gas supply. ALLMANNA SVENSKA ELEKTRISKA A.B. 24 April, 1968 [25 April, 1967], No. 19288/68. Heading H1B. A fuel cell electrode forming at least part of a wall of a gas chamber through which an electrode active gas can pass from an inlet to an outlet is characterized by a porous wall situated across the chamber in the path of the gas, the wall covering no more than 25% of the electrode surface and effecting a gas pressure drop at least equal to half of the total gas pressure drop from inlet to outlet. The wall may be a sheet of fibres or sintered particles, situated midway between the inlet and outlet perpendicular to the direct flow of gas from one to the other. It may be made from a metal or thermoplastic, e.g. P.T.F.E. or poly(ethylene glycol terephthalate). If of metal, it may constitute an electrical connection. A fuel battery may comprise a plurality of such electrodes having a common inlet channel and a common outlet channel. The gas may be oxygen, air, ammonia or a mixture of nitrogen and hydrogen produced by cracking ammonia. In a particular embodiment (Figs. 1-3, not shown) a fuel cell battery comprises a stack of electrodes having circular frames which are thicker than the electrodes themselves so as to space them and provide alternate reactant and electrolyte chambers. The electrodes are of nickel activated with platinum and have a finer pored layer on the electrolyte side. The electrolyte is aq. KOH.

Title: Improvements relating to speed-regulated filament winding machines
IPC: B65H59/38
Filed: 1956-06-22
Abstract: 809,866. Spindle driving and stopping arrangements; tension regulating. HOLLANDSE SIGNAALAPPARATEN, N.V. June 22, 1956 [June 24, 1955], No. 19421/56. Class 120(2) In a yarn winding machine of the kind in which a take-up spindle is driven by a pulley 19, Fig. 1, against which a driven belt or rope 18 is pressed with variable force by a displaceable idler pulley 14, the yarn, on its way to the take-up package, passes in a loop over a pivoted arm 1 biased in the direction of maximum loop length, arm 1 being coupled to a movable support 16 of pulley 14 so that when the length of the yarn loop is decreased the corresponding displacement of pulley 14 results in a decrease of pressure of belt 18 against pulley 19. As shown, Fig. 1, yarn from a skein 3 passes over a rod 5 and in a loop over a guide roller 2 to the take-up tube 6. Roller 2 is carried by arm 1 which is counter-weighted at 9 and pivoted in a block 11 on a support 12. When unwinding is impeded by entanglement of the skein, roller 2 is pulled downwardly and the movement of arm 1 acts through a link 13 and an arm 23 to swing support lever 16 up about a pivot 17 whereby the pressure of control pulley 14 against belt 18 is gradually relieved. If no further unwinding is possible, arm 1 is rotated to such an extent that pulley 14 is lifted completely from belt 18 and the spindle is stopped. In another arrangement, Fig. 4, an additional yarn guide pulley 301, carried by a spring-mounted arm 302. has a low moment of inertia compared with the control arm and absorbs any rapid variations in the unwinding speed. A flexible coupling 312 ensures that movements of pulley 307, due to operation of a stop motion, are not transmitted to the control arm. Stop motion contacts 308, 309 may be provided; these contacts close to stop the machine when pulley 307 moves beyond a position corresponding to the highest permissible winding speed, as when the yarn breaks or runs out. To avoid movement of pulley 307 influencing adjacent spindles, pulley 367 may be arranged to rest on the belt between the spindle driving pulley 310 and an auxiliary idler pulley 311 with a fixed axis.

Lighting and heating systems.-Lighting and similar systems comprising a generator driven by an internal-combustion engine are provided with a starting accessory working at a lower voltage than the lighting mains. This is effected, in the arrangement described, by coupling the shaft 2 of the lighting generator 4 to a small starter machine 5 and providing an automatic switch 11, which, when any of the lamps 37 is turned on, connects the starter to a battery 22, 24. The automatic switch, in the same action, breaks connexion across contacts 21, 23 which previously short-circuited the primary of the sparking magneto 35 to earth. The engine 1, thus started, is coupled direct to the shaft of the generator 4. An automatic switch 6 operates, when the generator voltage is sufficient to cut out the starter machine. The arrangement may be modified so as to leave the starter machine in circuit with the battery for the purpose of charging. The automatic starting- switch remains energized so long as any current is being used in the lamps. In order that this switch may carry the working current without injury it is constructed with a fine-wire winding and a thick-wire winding in parallel, the fine-wire winding giving the initial response and the thickwire. winding being thrown in at the end of the stroke.
