Abstract:
1. A process for conversion of chemical energy directly into electrical energy which comprises the steps of supplying an aqueous solution of hydrazine to the interface between an anode and an aqueous electrolyte in a fuel cell, supplying an oxidizing agent to the interface between a cathode and an aqueous electrolyte in said fuel cell said anode and cathode being ionically connected, and electrically connecting said anode and cathode through an electrical load.
Abstract:
The present invention is a new rotary engine consisting of a stator with a cylindrical cavity, a hollow cylindrical rotor located within the cylindrical cavity of the stator, a power shaft along the axis of the stator and an eccentric mounted on the power shaft. A plurality of spaced vanes are mounted in the stator for reciprocal movement with respect to the stator to provide working chambers between adjacent vanes, the stator, and the rotor so that rolling movement of the rotor around the interior of the stator in response to combustion of explosive charges in the chambers causes the eccentric to roll around the inner surface of the rotor and thereby rotate the power shaft.
Abstract:
The rotary piston engine has a hollow cylindrical piston (24) rolling inside a casing (20) supporting by a low-friction bearing (56) on an eccentric (54) mounted on a shaft (50) coaxial with the casing. The outside dia. of the piston is 75-95% of the inside dia. of the casing and the whole moving assembly is so dimensioned that, as the piston axis moves in a circular path about the casing axis (32), the min. distance between piston and casing is small. Seals are fitted between the flat end faces of piston and casing, and there are several flat rectangular blades (60) constrained to slide radially in the casing so as to remain in permanent surface contact with the piston. Hence, an uneven number of variable volume chambers is created between piston and casing. Each chamber has poppet inlet (7o) and outlet valves, in a cylindrical part of the casing, operated by a timer on the main shaft (50). A spark plug may be fitted there.

[Also in Divisions C2 and C3] Laminates are obtained by heat curing a plurality of laminae impregnated with a resinous condensate of 1,2-bis-(4,6-diamino-s-triazin-2- yl) cyclobutane and at least one aliphatic, aromatic or heterocyclic aldehyde or formaldehyde precursor and, optionally, another polyamino compound, e.g. urea. The resin is applied to the laminae as a solution in water and/or ethanol and the sheets subsequently air dried before heat-curing under pressure. Examples 6, 8-10 and 12 relate to the preparation of paper laminates using resins in which the aldehyde component is formaldehyde or acrolein. Example 7 describes the preparation of a veneered plywood using a formaldehydebased resin.
