Title: Solar control and shading system - has inclined reflectors preventing mid-day summer sun striking heat-absorbent outside wall of building
Inventor: KOESTER HELMUT DIPL ING
IPC: F24S23/79
Filed: 1979-07-25
Abstract: Two transparent parallel side walls are joined by cross-pieces . The space between two transparent flat cross-pieces is filled with air, another gas or it can be evacuated. The resulting 'cavity unit' is positioned in front of a heat-storing outside wall of a house or building. Reflecting foils are attached to the upper faces of the cross-pieces and are reflecting on both their upper and lower faces. The building's wall is coated with an absorbent paint slope. The cross-pieces at an angle to the horizontal. This angle (alpha) depends on the geographic latitude at which the building is located and is a function of the angle of incidence (beta) of the sun's rays. The midday summer-time sun rays are prevented from striking the heat-absorbing outside wall of the building.

Title: Reciprocating supercharged IC engine - has inlet valve timed to make expansion ration greater than compression ratio
Inventor: WIESER RUDOLF DR
IPC: F02D13/02
Filed: 1979-07-25
Abstract: A piston reciprocates in a cylinder surrounded by a cooling air jacket. Exhaust gas drives a turbine which is coupled to a compressor. This discharges air through the cooling jacket and the air is heated in flowing through the jacket. Part of the heated air reaches the inlet valve and enters the cylinder for combustion. The remainder flows to a turbine which is coupled to the exhaust gas turbine and air compressor. The inlet valve is timed to close between 60 and 90 degrees after bottom dead centre on the compression stroke. The expansion ratio is thus greater than the compression ratio.

Patent DE-3037286-A1 (DE)
Inventor: HOUWER GERKE
IPC: F04D17/16
Filed: 1980-10-02
Abstract: A circular cylindrical container (2) has a horizontal partition (14, 14a). Situated below the partition (14, 14a) is the water-storing space (5). Situated above the partition is an impeller (10) with a porous impeller part (10a). A porous hollow cylindrical mat (9) surrounds coaxially the impeller (10) and is immersed in the water in the space (5). In operation, air flows from the impeller part (10a) through the mat (9), absorbs moisture therein and emerges from the container (2) through the outlet duct (18). As a result, the evaporated quantity of water per unit volume of air is increased, because the tangential flow component of the air quantity flowing out of the impeller part (10a) is also utilised. <IMAGE>
