Title: Improved fuel cell electrodes
IPC: H01M4/86
Filed: 1960-05-09
Abstract: The walls of the larger pores of the catalystcontaining carbon fuel cell electrode of Specification 900,451 are coated with a solid polymer having a lower free surface energy than the carbon, said polymer being formed in situ on the walls.  Polymers specified are silicones and tetrafluoroethylene, and polymers and copolymers of ethylene, propylene, 3 methyl butene-1, 4 methyl pentene-1, and 4,4 dimethyl pentene-1.  The electrode may be first treated with a polymerization catalyst by filling the pores of the electrode with nitrogen, immersing the electrode in a solution of the polymerization catalyst, varying the gas pressure to produce a desired flooding of the pores, and repeating the operation with a solvent to wash out the polymerization catalyst. (The polymerization catalyst may be according to U.S.A. Specification 2,827,445).  Coating may then be similarly effected with the monomer and polymerization thereof allowed to proceed at room or elevated temperature.  Pores having a diameter of 8000  or more may be coated.  The polymer coating may be 2-1000 millimicrons thick.

Abstract: 332,683. Columbia Graphophone Go., Ltd., (Capps, F. L.). May 28, 1929. Tool-arms. -In electric pick-ups having a stylus formed by a length of thin wire, provision is made for feeding forward the wire when required, for limiting the feed, and for preventing the stylus-holder contacting the record when the projecting wire wears away. The stylus wire is led from a coil 75, Fig. 3, over a plate 74 having a struck-up tongue 77 which prevents backward movement of the wire, and passes through the coil 66 of the pick-up and through the stylusholder 68 which is attached to the armature 67 carried by a flexible member 69 secured by bolt 71. The wire can be fed forward, when worn, by a lever 83 pivoted to a block 78, Fig. 4, which is provided with a shoulder 82 and pivoted on a frame 72 secured to the magnets. On rocking the lever 83, a lug thereon first pinches the stylus wire against the shoulder 82 and further movement feeds the wire through the holder 68 until arrested by a stop 94, which has been moved opposite to the holder by the movement of the lever 83. This stop, which normally protects the end of the stylus-holder, comprises a V.shaped frame with bent-up end and with bent side lugs forming pivots against a plate 85 on the pick-up against which it is held by a spring. A projecting end 89 of the frame extends into the path of an arm 91 of the lever 83, whereby the stop is operated by movement of the lever, the return movement of which is effected by a spring 80. The passage through the stylus-holder may be heart-shaped providing a V which grips the stylus when in operation, and the end of the passage may be curved as shown in Fig. 6, to increase the grip. Specification 332,889 is referred to.

Title: Improvements in apparatus for adding proportional doses of fluid to water or other liquid flowing under pressure

Abstract: 612,738. Mixing fluids in flow. CANDY, F. P., and THOMAS. W. D. J. May 31, 1946, No. 16524. [Class 86] Apparatus for adding proportional doses of fluid to water flowing under pressure comprises two motive units operated by the water and working a fluid injection pump or pumps, each unit having a double acting piston (or an equivalent pair of single acting pistons) working in a cylinder and furnished with a piston rod which operates a valve that controls the reciprocation of the other unit. Water under pressure is fed through a pipe 19, Fig. 1, to valves 7, 8 controlling the working of pairs of opposed single acting pistons 3, 3 and 4, 4 mounted in cylinders 1, 2, respectively. A plunger pump 17 is operated by an extension of the piston rod 5 carrying the pistons 3 to inject doses of treating fluid through the pipe 16 into the water discharged from the cylinders 1, 2 through the pipe 15. In the position shown the valve 7 allows the water to pass through an opening 11 to the left-hand end of the cylinder 2 to drive the piston 4 to the right, whilst the water to the right of the piston 4 exhausts to the outlet pipe 15 through the valve opening 12. During. this movement of the piston 4 one of two collars 10 on the piston rod 6 displaces the valve 8 to connect the pipe 19 through an opening 14 to the left-hand side of the piston 3, so that when the movement of the piston 4 ceases the piston 3 is moved to the right. An opening 12 is then connected with the water inlet 19 on the movement of the valve 7 by one of two collars 9 on the piston rod 5, and the piston 4 is moved to the left, so that water is exhausted through the opening 11 which is connected by the movement of the valve 7 with the outlet pipe 15. The valve 8 is displaced by the second collar 10 on the rod 6 to connect the opening 13 with the water inlet 19 so that the piston 3 is moved to the left, and the cycle of operations is repeated. Means is provided for preventing accidental movement of the valves 7, 8 from their extreme positions and this means may be combined with a counter device for registering the number of strokes and/or the volume of water passed.

Class 38 (v) In a circuit-breaker similar to that described in Specification 684,311, the contact-carrying section 8b of the switch arm is connected to a pivoted base portion 8a, and to the operating linkage 13, 20 by a pivot pin 17 engaging in slots 8d in ears 8c of the contact section. The contact section is biased by a coil spring 12a secured to the housing, Fig. 3, or by a spring 12b encircling a headed pin 12c fixed to the portion 8a and extending through an aperture in the section 8b, Fig. 6. The function of the pin- and-slot connection is to enable a wiping action to occur at the contacts and if the contacts should become bonded together, the pin 17 on reaching the end of the slots gives an impact to the contact section 8b to assist in breaking the bond. The circuit breaker in addition to electromagnetic tripping may also have a thermal tripping member comprising a coil 37a of thermostatic metal secured to a shaft 32 and having an end portion which bears against the armature 34a. As the temperature of the circuit-breaker rises the armature is moved by the coil 37a closer to the electromagnet 44-46. Specification 684,327 also is referred to.
