Title: High pressure water jet for cleaning rock or other materials -  has composite nozzle with centre cone and mixing chamber supplied with air and water
Inventor: SUESSE HARALD DIPL ING
IPC: B26F3/00
Filed: 1991-06-20
Abstract: The device is used for cutting or cleaning rock or other material. It uses an accelerated water jet which is forced through a nozzle and has flexible feed lines for air and water. The centre piece of the nozzle (7), which, together with the mouth piece (8), forms a mixing chamber (18), has split nozzles on its outer rim which discharge directly into the flow channel (19). The air line in the flow channel (19) with tangential directional flow occurs in such a way that the steady cross sectional decrease of the flow formed by the body of the nozzle (1) and the centre piece (7) steadily accelerates the air flow likewise. There is a compression and mixing region (21) leading to a narrow air and water exit channel (22). USE/ADVANTAGE - A self regulating high pressure jet of water for cutting and cleaning rock or other material.

Title: Interface circuit for motor vehicle control computer - has input level detector for sampling input pulses, and stores output in memory for noise suppression
Inventor: SAYAMA MASAHIKO
IPC: G06F3/00
Filed: 1991-07-17
Abstract: The interface module (12) contains two identical parallel input channels of opposite polarity.

Title: Antiphlogistic pharmaceutical based on camomile extract - contains a matricin-rich, dry, camomile extract
Inventor: SCHMIDT PETER C PROF DR
IPC: A61K36/28
Filed: 1991-07-19
Abstract: A pharmaceutical based on a camomile extract contains a matricin-rich, dry camomile blossom extract.

Patent DE-4203100-A1 (DE)
Inventor: DENZ HELMUT DIPL ING
IPC: F02M25/08
Filed: 1992-02-04
Abstract: A process for testing the operativeness of a tank ventilation system in a vehicle with an internal combustion engine which has a pressure sensor fitted in the tank, an adsorption filter connected to the tank via a line and a tank ventilation valve connected to the adsorption filter via a valve line, in which system the adsorption filter has a ventilation line which can be closed off by a stop-valve. The process makes use of the knowledge that both the build-up and the decrease gradient for the underpressure in the tank depend substantially similarly on the level in the tank. If, for instance, the quotient of the build-up and decrease gradient is used as the evaluation quantity, it is therefore substantially independent of the level, permitting a very reliable comparison with a threshold value. If the build-up/decrease gradient quotient is found to be greater than the threshold value, the system is regarded as non operative. This procedure makes it possible to detect leaks with diameters of the order of 2 mm.
Patent DE-4205969-A1 (DE)
IPC: B41M3/00
Filed: 1992-02-27
Abstract: The invention concerns a process for producing porous moulded bodies with a predetermined pore structure. This involves shaping a plastically deformable material which can subsequently be set, and is characterized in that the moulded body is built up in layers by repeating the following two-step sequence: production of a layer from the material whose structure reflects the original bone pore system; hardening of the layer, the structure of each layer being copied from the corresponding bone models. This process is to be preferred in the production of moulded bodies with three-dimensionally interconnected pores, and particularly in the manufacture of moulded implants with the porous structure of natural bones.
