Title: Piston engine
Inventor: GAIL JOSEF
IPC: F02B57/08
Filed: 1989-09-27
Abstract: The piston engine, has a housing (1), with rotor (5), rotating about a first rotary axis (7). The rotor has three pair of cylinders (15) located at 120 deg relative to each other. The cylinders have pistons (17), rigidly connected to each other via piston rod (19). A crankshaft in the housing rotates about a second axis (25), which is located excentrically to the first by a certain distance (e). The piston rods of a piston pair, are held in excentric bearings (27,31), on the crank shaft.  These define rotary axis (33), at 120 deg relative to each other.

Filed: 1989-11-21
Abstract: In order to be able to distinguish coloured copies from original documents, e.g. driving licences, the original is printed with one fluorescent and one non-fluorescent offset ink, these inks having approximately the same colour shade, e.g. the colour shade orange. In the copy, the fluorescent colour is reproduced in the incorrect shade, e.g. in the case of orange the colour seen will now be mid-brown, so that the colours orange and mid-brown appear on the copy.

Title: High pressure pipe cleaner - avoids pressure fluctuations on pump drive by blocking off outlet valve of pump valve
Inventor: LEISTIKOW JOACHIM
IPC: B08B9/04
Filed: 1989-11-27
Abstract: The pipe cleaner comprises a high pressure pump with several pump pistons set in a time-staggered sequence.

Title: Measuring procedure for ascertaining geometry of prosthesis - deriving coordinate values by positioning fluid sensor at certain points on surface and allowing its released fluid to load surface
Inventor: TRAUER BORIS FAIRLIE
IPC: A61C13/00
Filed: 1991-01-10
Abstract: A length measuring principle is bifunctional applied. A variable surface load is applied to deform the object to be measured and produce a measuring force for length and setting the coordinate values. A fluid at a supply pressure flows through a nozzle to a point on the object fixed relative to the coordinate system laid down by the measuring arrangement. The object surface is thus deformed in dependence on the supply pressure and distance of the nozzle from the object. The pressure head of the nozzle can be measured from these factors. The position of the measuring point subjected to the fluid stream can be spatially determined from the position of the nozzle. A selected number of measuring points on the object surface allows the geometry of the object to be derived. USE/ADVANTAGE - Computer-aided prodn. of prosthesis shafts. Reproducibly settable parameters allow series of trial samples to be made for optimally matching to patient requirements.

Inventor: STEGMAIER ALWIN
IPC: F02M61/20
Filed: 1991-09-21
Abstract: In prior art electromagnetically operable injection valves, an adjusting bush is pressed into a flow drilling of a core in order to set the force of a return spring. In the upstream end of the flow drilling is fitted a fuel filter which retains finely divided suspended particles in the fuel. In the novel injection valve, the fuel filter (30) has a filter casing (37) on which is supported the return spring (26) and which is connected to a frame (31) pressed into the flow drilling (25) so that the force introduced into the fuel filter (30) by the return spring (26) is conducted via the filter casing (37) and the frame (31) into the core (2). No adjusting bush for regulating the spring force is thus necessary. The novel injection valve is suitable in particular for fuel injection systems in mixture-compressing internal combustion engines with spark ignition.
