Inventor: BACHHOFER BRUNO
IPC: A61L9/00
Filed: 1979-08-29
Abstract: An air washing apparatus consisting essentially of two separate cyclic units. In the first cyclic unit, air is sprayed with a fluid consisting of water and a halogen. The spray removes impurities from the air, and brings the impurities into the fluid supply from which the impurities are removed in the second cyclic unit, by treating the fluid with ozone. After treatment, the fluid is returned to the fluid supply where the halogen in the fluid supply removes any ozone present, and thereby renders the fluid safe.

Inventor: WEIN GEDEON ING
IPC: F25D21/08
Filed: 1979-09-08
Abstract: Situated upstream of the evaporator (1) there is at least one cold storage space (6) and between the latter and the evaporator (1) there are fans (2) for conveying cold air from the evaporator (1) into the cold storage space (6). These heating elements (4) are arranged outside the evaporator (1) in the air stream of the fans (2) on their side facing away from the evaporator. When the passage of coolant is switched off, the fans (2) can switch on so that the air stream produced by the fans (2) flows over the heating elements (4). As a result, after the heating elements are switched on and the passage of coolant is switched off, the heat of the heating elements defrosts the evaporator. <IMAGE>

Title: IC engine with steam injection - has steam generator heated by exhaust gas from engine
Inventor: STARKER KARL-GEORG
IPC: F01L1/12
Filed: 1980-05-07
Abstract: The engine has a carburettor (17) which supplies an air/fuel mixture to the cylinder (2) through an inlet valve (5). Hot exhaust gas leaves through exhaust valve (4) and is led to a steam generator (3). The water supply for the steam generator is taken from the engine cooling water system by a three-way valve (11). The generated steam is controlled by a valve (21) and is injected into the engine cylinder through a steam inlet valve (6). Some of the thermal energy in the exhaust gas is therefore recovered and converted into useful work.
