Title: Cell electrodes
IPC: H01M4/86

Abstract: 1347534 Transition metal carbides and nitrides, silicides and borides ROBERT BOSCH GmbH 28 May 1971 [4 June 1970 23 Dec 1970] 17731/71 Heading C1A [Also in Division H1] In producing a fuel cell electrode at least the surface regions of which comprise a carbide, silicide, nitride or boride of at least one of the transition metals Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co and Ni, the transition metal compound is obtained by reacting a solid component, which has been dissolved and reprecipitated in a finely divided form, with one or more reactants which are gaseous or liquid, all the steps of the process being carried out at a temperature less than 700 C. and in the shortest time possible to effect complete reaction, so as to produce the compound in a form having a large specific surface and a large number of reactive sites, the compound being prepared on a porous carrier material, to give the desired electrode, or after formation being mixed with a pore-forming material and pressed in a mould to give the desired electrode. The further reactant used is preferably a gas and the reaction may be completed within six hours. The solid used may be a metal powder or precipitated metal acid, i.e. a material of formula H x MO y  precipitated from a salt solution of M wherein M is tungsten or molybdenum, a metal oxide, a metal oxide hydrate or a metal hydride. The formed electrode may be soaked with distilled water or with electrolyte-fuel mixture before it comes into contact with the air. The porous carrier used may be carbon paper, carbon felt, carbon cloth or carbon ribbon. The porous carrier may also be a molecular sieve or an organic or inorganic ion exchanger. The porous carrier may be soaked with a solution of a compound of at least one transition metal, the solute converted by chemical reaction into a finely divided insoluble compound within the pores of the porous carrier which insoluble compound is then converted into the corresponding carbide, silicide, nitride or boride by reaction with a gaseous compound of carbon silicon, nitrogen and/or boron at an elevated temperature. The solution used may be that of an alkali metal salt of at least one transition metal acid as defined; which is precipitated in the pores as a metal acid hydrate by acidification, the product dried and the corresponding carbide is then produced by reaction with carbon monoxide at 600 to 700 C. If desired an aqueous suspension of a metal acid, as defined above, hydrate may replace the aqueous solution.

Abstract: 530,283. Locking rods. AUTOMOTIVE PRODUCTS CO., Ltd., and CLENCH, E. C. S. June 20, 1939, No. 18022. Addition to 443,871. [Class 80 (iii)] [Also in Group XXIX] The means described in the parent Specification for locking a slave-unit at any point in its range of movement are provided with a resilient device which is deformed when the slave-unit is operated, and on returning to normal condition urges the locking-means into fuller engagement and thereby prevents backlash. The slave-unit shown in Fig. 2 is employed for opening and closing a valve, and comprises a pistonrod 18 provided with loose pistons 39, 40 engaging a liner 38 in a cylinder 23. A rubber bush 28, mounted in the piston-rod, engages a loose sleeve 30 formed with conical surfaces 31, 32 co-operating with balls 33, 34 which abut on spring-urged washers 36, 37. When pressureliquid is admitted above the piston 39, a projection 47 thereon releases the balls 33, the piston engages the sleeve 30, pressure is transmitted through the bush to the piston-rod, and the valve is closed, when the liquid pressure falls, the bush urges the sleeve and piston-rod upwards and downwards, thereby ensuring full locking- action of the balls, and holding the valve on its seat. When pressure-liquid is admitted below the piston 40, the piston-rod is raised 'and the bush acts in the above-described manner. In a modification; providing a uni-directional lock, the bush 28 is omitted, and the cylinder 23 can rise slightly in opposition to strong springs when pressure-liquid is admitted at the top. When the pressure falls, the springs depress the cylinder, and the locking-balls are firmly jammed.

Abstract: 1,133,061. Manufacturing heat-shrinkable plastics. F. ADANY. 25 April, 1966 [26 April, 1965], No. 18077/66. Heading B5A. A heat-shrinkable sheathing of plastics material, e.g. polyethylene cross-linked by irradiation, is formed by passing a pre-extruded tube 9 enclosed by a conveyer belt 3 through a tubular heater 2, expanding the tube 9 without longitudinal stretching so that belt 3 contacts the internal surface of heater 2, progressively increasing the temperature of tube 9 as it moves through heater 2 and rapidly cooling it as it emerges therefrom. Tube 9 may be taken from a reel, the coiled end of the tube being connected to a source of gas under pressure, and the treated tube may be wound on a further reel after it has passed between niprollers 11 which maintain a constant pressure, e.g. 5 cm. of Hg, within the tube. Belt 3, driven by motor 6, may be of glass-fibre reinforced PTFE, and is wrapped around tube 9 by a series of rings 7 whose diameters decrease in the downstream direction to that of the bore of heater 2. Heater 2 comprises a metallic casing 1a surrounded by a resistance element 1b and insulation 1c. Element 1b comprises a wire in the form of a helix whose pitch decreases in the downstream direction to a zone of maximum temperature, e.g. 130-140 C., where the pitch is a constant minimum. Cooling device 10 may be an air blower.
