Title: Fuel injector for internal combustion engine
Inventor: POTZ DETLEV DR ING DR
IPC: F02M61/18
Filed: 1996-05-22
Abstract: The valve body (1) has a central bore which accommodates a valve rod (11) which has a number of grooves in the top part so as to make a star-shaped section. The bottom part (13) is cylindrical and of larger diameter so that it fits closely in the bore and acts as a piston.

Patent DE-19703775-A1 (DE)
Inventor: JUNGBECKER JOHANN
IPC: B60T8/50
Filed: 1997-02-01
Abstract: An electromagnetically controllable multiple way control valve for hydraulic, anti-lock motor vehicle brake systems puts at least one wheel brake (wheel) in hydraulic communication with a high-pressure source (THZ) or a low-pressure reservoir (NDS) and comprises a slide (6) guided in a cylindrical housing body (2) prestressed in both directions in the longitudinal direction of displacement (4), as well as an elongate opening (33) in the longitudinal direction. During normal operation of the brakes, the slide is prestressed towards a first end position in which the wheel brake is in fluid communication with the high-pressure source and cut off from the low-pressure reservoir. A valve (60) provided between the wheel brake and the low-pressure reservoir is opened to reduce pressure in the wheel brake. To prevent the slide (6) from getting stuck during normal brake operation, the multiple way control valve has a longitudinally movable pressure piston (48) arranged in the opening (33) of the slide (6). During normal brake operation, the pressure piston (48) acts with its free end (50) against the force that prestresses the slide towards the first end position, so that the slide (6) can move back and forth in the longitudinal direction depending on the pressure of the high-pressure source.

Inventor: BICKERT STEFAN
IPC: B29C35/08
Filed: 1997-02-21
Abstract: The invention relates to an apparatus for the photo-initiated chemical cross-linking of material (28). To form one or more mouldings the material is enclosed in an optically transparent mould (26). The apparatus has at least one light source (12), for example a pulsed UV light source by which the material (28) can be acted upon by a light that triggers the cross-linking. The region to be cross-linked in the mould (26) is determined at least partially by beam-delimiting elements (20; 22) between the light source (12) and the mould (26). That can be achieved by arranging between the light source (12) and the mould (26) a mask (20) having transparent and non-transparent surface portions. The mask (20) is then projected onto the material (28) that is enclosed in the mould (26) by projection optics (24). The projection of the mask (20) onto the material is effected in a telecentric beam path.
