Patent DE-4222533-A1 (DE)
Title: Vehicle IC engine control system - operates engine under full torque conditions with control for optimum gear ratio and optimum fuel consumption.
Inventor: MALLINCKRODT ULRICH VON
IPC: F02D13/02
Filed: 1992-07-09
Abstract: The engine control operates under similar conditions as for full load with changes in the engine torque through throttle adjustment and with an infinitely variable transmission. The control program sets operating parameters for min. fuel consumption, i.e. for min. throttle setting at any set speed. The control incorporates time control for the setting adjustment as well as the actual settings themselves. Each cylinder operates with optimum efficiency for min. emission products. The reduced engine speed reduces engine wear and thermal stress. The engine operates with min. engine speed to achieve the selected torque. ADVANTAGE - Improved engine life, improved fuel efficiency. Reduced maintenance requirements.

Patent DE-4223971-A1 (DE)
Title: Paddle blade system for utilising wind or water power to produce e.g. electric power - is designed, e.g. as frameless, large area kinetic plates arranged respectively against open carrier frames in any number around paddle wheel shaft
Inventor: LUECKE HANNS W
IPC: F03B17/06
Filed: 1992-07-21
Abstract: The paddle blades (3) are located in such a way that their juxtapositions are arranged, e.g. across hinge connections, in the region of the outer ends of the frames (2) so that the swinging in or out of the paddle blades towards or away from the axis (1) is facilitated. In the swung out position no energy is taken. The paddle blades are hinged/pressed by the pressure of the kinetic energy in a half circle rotation against the respective carrier frame (2), thus they are power effective. In the other half circle rotation (opposite half circle), they swing out in the centrifugal direction of the kinetic energy so that with opened carrier frames the blades are not power effective, namely, corresp. opposite running forces are minimised. ADVANTAGE - Cost effective utilisation of kinetic wind and water energy. Any size of system can be incorporated in different machines. Wide environmentally friendly application. Can be coupled to generator to produce electrical power.

Patent DE-4334473-A1 (DE)
Inventor: KRIEGER KURT F
IPC: F26B13/10
Filed: 1993-10-11
Abstract: A device (100) for the suspension guidance of a travelling paper or paper-like web (B) by air and which is especially useful for deflecting a damp travelling paper web. The device has a plurality of air ducts (13) extending over the width of the web and bounded by wall surfaces (14). Each air duct (13) has a nozzle arrangement (22,22') communicating with a pressure chamber (10) to which compressed air is applied. In the air ducts (13) there are also air inlet apertures (26) which are not in fluid connection with the pressure chamber (10) but communicate through an intake duct (27) with an intake chamber (17) in which ambient pressure prevails and which has an inlet (19) for the fluid. Additional inlets (26) convey an additional quantity of air into each of the air ducts owing to the injector effect of the compressed air flowing into the air duct, thus preventing the web from forming a curvature transverse to the direction of its movement corresponding to the air duct cross-section and reducing the power consumption of the device by some 25% as compared with conventional suspension guidance devices.
