Title: Wind-power generator as electrical current source - has vertical sail in a rectangular frame mounted in circular hoop with rollers, travelling on parallel rails
Inventor: HARTMANN KONSTANTIN
IPC: B61C11/06
Filed: 1992-10-14
Abstract: A wind generator has a sail formed from a rectangular steel frame, inlaid with canvas or nylon-strengthened plastic.

Title: Cap for a burner
Inventor: POESCHL GUENTER
IPC: F23D11/40
Filed: 1993-09-22
Abstract: A cap (14) for at least one burner (8), equipped in particular with a flame tube (10), of a heating boiler with furnace has a cover (24) which delimits the cap from the furnace. Only heating-gas outlet openings (20) form a flow connection for resulting heating gases. In the interior of the cap (14), a separate flame space (28) is thus formed, as a result of which modern burners, which reach high flame temperatures, can be installed in already existing boilers in which a furnace wall is not designed for the high flame temperatures of the burners (8). The cap (14) absorbs part of the resulting energy, as a result of which the heating gases leave the cap (14) at a lower temperature, and releases the energy uniformly to the boiler. <IMAGE>
