Title: Gasifier plant
Inventor: POLONSKI CZESLAW
IPC: C10J3/44
Filed: 1985-05-13
Abstract: In gasifier plant, the exhaust gas from a thermodynamic engine (2) (for example a diesel engine, a gas turbine or a Stirling engine) is utilised as a source of carbon dioxide and steam for a gasifier (1). In the gasifier, the carbon dioxide and steam react with carbonaceous material such as coal or domestic or industrial waste to generate a fuel gas containing carbon monoxide and hydrogen. This fuel gas may be used as feedstock for a process plant or used as fuel in the thermodynamic engine. Thus coal and other solid biomass may in effect be used as fuel in (for example) an internal combustion engine. <IMAGE>

Title: Pedal-powered boat
Inventor: BRITTON MARTYN NEIL
IPC: B63H16/20
Filed: 1986-01-30
Abstract: A pedal boat consists of a bicycle style transmission 10, 14, 13 coupled through a long propeller shaft 16 to a power boat type propeller and housed within a lightweight and streamlined hull. As the gearbox assembly is well forward in the hull a very long propeller shaft is used which gives an excellent thrust line. In addition, as the forward end is above the water line the need for a water seal and consequent friction is removed. The above arrangement is fitted in two basic hull types, viz a small planing hull designed for 'pottering' or racing on sheltered waters and a long canoe style craft which is fitted with equipment for long distance travel on inland waterways. The hull may terminate with a bulkhead to which bow sections of different length can be attached. <IMAGE>
