1,167,225. Sintered cermets. TEXAS INSTRUMENTS Inc. Feb. 24, 1967 [March 4, 1966], No.8875/67. Heading C7D. [Also in Division H1] ] A sintered cermet is made from a powder mixture comprising by weight 80-98% Al and 20-2% aluminium silicate which is compacted at 10, 000 p. s. i. and sintered at 1000‹-1400‹C. for 4 to 8 hours in an oxidizing atmosphere. The powder mixture may alternatively be hot pressed. The aluminium silicate used is kaolin Al 2 O 3 (SiO 2 ) 2 À2H 2 O or Al 6 Si 2 O 13 or Al 2 SiO 5 and the sintered cermet may be used as a spacing member in a fuel cell using molten LiNaCO 3 as an electrolyte.
Abstract:
A multicolor thermally sensitive paper having a supporting substrate with a first coat of material normally of a first color reacting in response to a given quantity of heat to turn into a contrasting color with a second coat overlaying the first coat in the form of an opaque blush coat thermally adapted to be transparentized in response to a quantity of heat lower than the given quantity.
Abstract:
Apparatus for reforming hydrocarbon fuels by admixing a hydrocarbon and water to form a feedstream, contacting the feedstream with an inorganic salt or mixture of inorganic salts in the molten state, and separating the gaseous effluent generated by this contact. After the hydrogen-containing effluent is removed from the molten salt, means are provided that the latter may be mixed with oxygen at a temperature and pressure sufficient to permit combustion between the oxygen and any residual carbon which may be retained in the salt, after which further means are provided to remove the gaseous reaction products of this combustion.

1,092,213. Secondary electrodes in fuel cells. TEXAS INSTRUMENTS Inc. Jan. 8, 1965 [Jan. 9, 1964], No. 26328/67. Divided out of 1,092,211. Heading H1B. A fuel cell electrode structure comprises a secondary electrode adjoining a porous electrode having a reactive surface area in contact with an electrolyte, said secondary electrode being in electrolyte transfer relationship with the porous electrode and extending outwardly from the body thereof, so increasing the effective reactant surface of the electrode. The secondary electrode may define channels (e.g. for fuel) contacting reactive surface of the porous electrode; this structure may interconnect and structurally support two porous electrodes, in which case the electrolyte may contact the sides of the electrodes remote from the secondary electrode and a gaseous fuel may contact the nearer sides and the secondary electrode structure. A typical embodiment is described in Fig. 21. This Specification has been divided from Specification 1,092,211, along with Specification 1,092,212 and describes batteries and cells also described in these Specifications.
