Patent DE-3246402-A1 (DE)
Title: Combustion engine with external combustion chamber
Inventor: EICKMANN KARL
IPC: F02G3/02
Filed: 1982-12-15
Abstract: By means of the invention the engines of the prior application are improved. In particular the engine with external combustion chamber and water or steam re-injection or introduction into the external combustion chamber on completion of the combustion process of the fuel in the hot compressed air is analysed. A method of calculation is developed and proposed for the entire engine. From this it emerges that the engine with external combustion chamber could not hitherto be realised because the high combustion chamber temperatures would melt away the housing of the combustion chamber. Accordingly the invention concentrates the combustion on a thin, broad gap, which can be easily cooled. Immediately following combustion, which is enforced at each point of the gap in a precise fuel-air ratio, the combustion gases are mixed with water, which immediately vaporises in the gases or with already preheated steam. Thus a quite considerable temperature reduction is achieved, whilst the evaporation and expansion of water or steam performs work. In one embodiment the engine can then function entirely without external cooling. The introduction of a work efficiency factor shows that engines according to the invention without any external cooling can approximate to those of diesel engines and moreover in addition to operation with liquid and gaseous fuels ...

Title: Handle for tennis and squash rackets, golf clubs, and for other bats or the like for ball games
Inventor: DEUS HANS-JUERGEN
IPC: A63B60/34
Filed: 1983-04-11
Abstract: To avoid the changing torsional moments on the lower arm which occur in the previously used handles due to the obtuse angle between the lower arm and the centre-line of the racket/club shaft, the handle is designed as shown in the drawing. Due to the inclination of the resting surface for the index and middle fingers, angle alpha, and of the resting surface for the knuckles of the ring and little fingers, angle beta, the racket/club shaft and centre-line of the lower arm form a straight line. Due to the resting surfaces for the individual finger joints and their angles relative to one another, an optimum transmission of force is achieved between the racket/club and the hand. By reducing the strain on the arm, the occurrence of so-called "tennis elbow" can also be avoided. Furthermore, due to the fact that the striking surface is parallel to the axis of the wrist, learning to play tennis is made easier and it is no longer necessary to change the grip on the racket for forehand and backhand strokes. <IMAGE>
Patent DE-3315927-A1 (DE)
Title: Feed device for constant-pressure injection systems of combustion engines
Inventor: MATTHEES KLAUS DIPL ING
IPC: F02M55/00
Filed: 1983-05-02
Abstract: The feed device according to the invention is intended for injection quantities with constantly pressurised but separately controlled injection valves, especially for motor vehicle engines. It comprises a high-pressure pump and feed pump driven by the engine, the feed pump feeding the intake side of the high-pressure pump. The object is to design the feed device so that before starting of the combustion engine the injection system is ready to operate. This is achieved according to the invention in that the feed pump is on the one hand coupled to an output shaft of the combustion engine by way of a one-way clutch and on the other hand connected by way of a further one-way clutch to an auxiliary engine, the pressure side of the feed pump being connectable by means of a reversing valve to the high-pressure circuit or, after the reference admission pressure has been attained, to the intake side of the high-pressure pump. In further advantageous variants, the generator may serve as auxiliary engine. <IMAGE>

Title: Method for producing resist layers photolithographically and photosensitive compositions which can be used therefor
Inventor: NAKAMURA YOICHI
IPC: G03F7/038
Filed: 1983-10-13
Abstract: The photosensitive compositions are suitable as photoresist materials in the photolithographic treatment of substrates and, in particular, of various semiconductor devices and they contain organic polymeric photoresist material and a polyorganosiloxane. The novel process produces fine image patterns of suitable resist layers photolithographically on substrates using photosensitive compositions of this type. The polyorganosiloxane contained in the novel photosensitive compositions is preferably polydimethylsiloxane. The addition of the polyorganosiloxane, in particular in an amount of 0.01 to 5, preferably 0.05 to 1, % by weight of the solids content of the organic polymeric photoresist material reduces or prevents, during contact exposure, damage to the photomasks which come into contact with the photoresist layer on the substrate since the adhesion of the photomask to the photoresist layer is prevented, or at least appreciably suppressed, by the presence of the polyorganosiloxane.
