[Also in Division C7] Thin porous electrodes having a first, porous layer supporting a second, catalytically active layer of greater porosity is made by depositing on a support by electrostatic projection a finelyscreened powder, sintering the layer of powder thus deposited and compressing it to reduce its porosity and form the first layer, and forming the second layer on the first layer. As shown in Fig. 1, a continuous strip of Ni gauze 1 is coated with carbonyl Ni by electrostatic projector 2 and the coating is then sintered in furnace 3 at 700 C. in H 2  and compressed between rolls 4 to form the first layer. The catalytically active layer is then formed by electrostatically projecting a mixture of Ni and Ag 2 O on to the first layer using projector 5, sintering the mixture at 350 C. under A in furnace 6, followed by a further sintering under H 2  in furnace 7. Optionally a gas compartment layer can be formed on the strip by depositing more Ni and sintering it using a further electrostatic projector and oven (not shown). Finally, electrostatic projector 8 deposits a waterrepellent such as PTFE on the strip which is cut to size by tool 9. An example describes the preparation of another electrode in which the first porous layer of Ni is sintered on one face of the gauze at 600 C., a composition containing a suspension of nickel-boron catalyst and carbonyl Ni in a solution of polystyrene in benzene is coated on the other face of the gauze and the coating is dried at 60 C. In another embodiment the first layer is formed by depositing the powder on a metal foil, rolling to compact the powder, stripping the foil from the deposited layer and sintering the layer.

Title: Improvements in or relating to machines for finishing bottom portions of boots or shoes or similar articles
IPC: A43D95/08
Filed: 1931-09-03
Abstract: <PICT:0388784/III/1> <PICT:0388784/III/2> A machine for finishing the bottom surfaces of boots and shoes &c., such as a machine of the type described in Specifications 285,102 and 306,065, [both in Class 95, Paints &c.], comprises a driven burnishing pad provided with a heating device arranged to be moved away from the pad when the latter is to be used.  As shown, the heater 6 for the pad 7 comprises electric heating means 13 and is mounted on a rock-shaft 5.  The heater is urged into engagement with the pad by a spring (not shown) which holds an eccentric 8 against a lug 10 extending from the arm 4 in which the shaft 5 is mounted.  The eccentric 8 is formed on one end of a shaft 9 rotatably mounted in the heater 6 and adjustable by means of a hand-wheel 11, being held in adjusted position by a spring washer between the wheel and the end of the bearing of the shaft 9. The operative position of the heater 6, and the amount of heat imparted to the pad, can thus be varied to some extent.  The pad is set in rotation by a treadle-operated rod 14 attached to an arm 15 fixed on the rock shaft 5.  Depression of the rod 14 actuates a belt-shifter 16 through a link 17 and moves a belt 18 from a loose pulley to a fast pulley on the driving shaft of the pad. Depression of the rod 14 also rocks the shaft 5 and moves the heater 6 away from the pad 7.  Fig. 2 shows a modified construction in which the pad 20 has a flat face instead of a convex face, and further adjusting means for the heater 21 are provided.  The heater 21 carries a pair of lugs 22 in which a shaft 23 passing through a block 25 is fixed by a screw 24.  A screw 26 fixes the shaft 23 to the block 25.  The lugs 22 are clear of the block 25, so that if the screw 26 is loosened the heater may be moved across the machine or tilted as desired about the shaft 23.  Movement of the heater in a transverse direction may be effected by loosening a screw 27 which secures to an arm 28 a stem 126 connected to the block 25.  The pad may be used to apply wax or to spread wax previously applied to the shoe surface, or the machine may comprise two pads, one for applying wax and one for spreading it. The apparatus is particularly intended for the waxing and burnishing of heel breasts and of tread faces close up to the heel breast.

[Class 97 (iii)] [Also in Group XXIX] The member controlling the operation of a device for locking a directional gyroscope simultaneously actuates a switch device connecting an automatic steering apparatus for the supporting craft into or out of circuit. As shown, the gyro 1 is locked about the horizontal axis 3 on which it pivots in the vertical ring 4 by the engagement of a roller 14 on an arm 13 pivoted to the ring 4 at 12 in a notch in a cam 11 on the axle 3. The ring 4 is locked about the vertical axis 5 by claw ring 8 which may be raised into engagement with a conical ring 7 fixed to the ring 4. The arm 13 and ring 8 are moved by screw and nut mechanism actuated by longitudinal movement of a plunger 15. The latter carries a coupling member 20 which, in the locking position engages a coupling member 21 on a worm 10, so that by rotating the plunger 15, a worm wheel 9, engaging the worm 10, and with it the claw ring 8 and ring 4 may be adjusted to reset the gyro in azimuth. A switch 23, maintained closed by a cam surface 22 on the plunger 15, closes the circuit to a solenoid. The latter adjusts a valve against the action of a spring and thus closes a byepass between the two pipes connecting the control valve of a fluid-pressure servomotor system with the servo-motor controlling the rudder. When the plunger 15 is pulled out to the locking position the switch 23 opens and the fluid pressure supply to the servo-motor controlling the rudder is byepassed, whereupon the steering of the craft may be effected manually. In a modification the gyro is locked and the automatic steering device simultaneously rendered inoperative by pushing in the plunger.
