Title: Recovery of valuable substances from body excretions and blood - by reducing the volume of the excretions, sepg. the valuable substance from the matrix, e.g. by filtration and e.g. chromatographing the retentate
Inventor: AHLERS ANDREAS DIPL CHEM DR
IPC: C07K1/36
Filed: 1991-08-31
Abstract: The recovery of valuable substances, esp. pharmaceuticals from body excretions such as urine and faeces, but also from blood, comprises collecting the body excretions contg. the valuable substances, reducing the vol., sepg. the valuable substance from the excretions (matrix), sepg. the retentate(s) obtd. and drying and working it/them up. The sepn. of the pharmaceuticals from the matrix is pref. carried out by filtration processes using different sizes of filters and/or chromatographic processes using different fillings for the columns. The filtrations are carried out in the manner of fractional filtration using filters of different pore size which first separate solids and microorganisms and then separate the pharmaceuticals into one or more retentates, depending on their m.wt. The retentates can then be subjected to chromatographic sepn. processes according to the affinity of the substances on the carrier materials. The fractions from the chromatographic processes are concd. in the form of eluates and vacuum dried. USE/ADVANTAGE - Pharmaceuticals which have only a short dwell time (1/2 life less than 12 hrs.) in the human body can be recovered so that is no, or less waste which would contaminate the environment and opt. re-used, which gives more economical use of the starting materials.

Title: Process simulating battlefield mine action against different targets - has sensor in mine working like conventional system by responding to signal emitted by target
Inventor: FRANCKE ERWIN
IPC: F42B8/28
Filed: 1991-10-25
Abstract: The process for simulating the working of different types of mine operates on different targets, e.g. anti-tank, anti-personnel or against mine-clearing machinery. Each simulation mine senses with an inbuilt mechanism, either an electrical or optical sensor any targets in its vicinity. Then, depending on the identification of the target the mine is triggered. The sensor of the simulation mine works in a similar manner to the original mine. The triggering of the mine is achieved by use of an evaluating logic which responds to a signal emitted by the target which may, in addition to identifying its type, also indicate its position, e.g. the axle of a truck. USE - Process is intended for mine warfare training and mine clearance under manoeuvre conditions.

Abstract: The invention relates to a torque limiting coupling 5 in which a plurality of driving elements 19 of slide-like design distributed circumferentially are arranged displaceably in the coupling hub 10. The unit is accommodated rotatably in a coupling sleeve 7. The driving elements 19 are urged with their torque transmission surface 25, provided at the head, into the correspondingly shaped recesses 22 of the coupling sleeve 7 by a spring arrangement comprising compression springs 38, 39. Due to the arrangement of the compression springs 29 and of the switching surfaces 30, 31 of the driving elements 19 and of the torque transmission surface 25 so as to be facing in the same direction towards the compression springs 38, 39, a moment contrary to the tilting moment resulting from the torque transmission is exerted on the driving elements 19 by the springs 38, 39 when torque is transmitted by the coupling sleeve 7 in the torque transmission direction N. This results in improved wear and switching behaviour. <IMAGE>

Title: Partial laser modification of surfaces - useful for shallow or deep engraving or inscription
Inventor: ABERLE HANNS-DIETER DR
IPC: B23K26/08
Filed: 1992-03-27
Abstract: Partial surface modification of metallic or non-metallic bodies is carried out using a Q-switched continuous wave Nd:YAG laser having opt. a beam expander in the beam path, a beam deflector with a computer-controlled rotary deflection mirror, and a plane field objective for focussing the laser beam, the laser being moved over the surface along one or more reference lines present by the computer. The novelty is that the laser beam is moved within an outline (U1, U2) delimiting the surface portion (A) to be modified, along reference lines forming the grid lines (R1, R2, R3) of a grid field (N) and then the entire grid field (N) is shifted at least once by a certain amount, while maintaining the relative position of the outline (U1, U2) and the entire surface portion (A) is re-scanned by the laser beam along the grid lines (R1, R2, R3). During each scan, the operating time and the energy content level of the laser pulses are limited so that material evapn. is effected with minimal plasma formation. USE/ADVANTAGE - The process is useful in laser engraving or insorption processes carried out e.g. on metallic or plastic surfaces. It achieves the prescribed shallow penetration depth for prodn. of inscriptions, but can also produce deeper penetration depths to achieve relief-like material surface removal.

IPC: F02M51/06
Filed: 1992-06-27
Abstract: A curved perforated injection plate for a fuel injection valve having at least one cylindrical injection aperture inclined obliquely to the longitudinal axis of the valve is known. The injection apertures are parallel to the longitudinal valve axis and produced by stamping the initially plane perforated injection plate, which is then bent at one end of the valve into a conical shape so that the cylindrical injection apertures are inclined in relation to the longitudinal valve axis. The novel perforated injection plate (22) also has at least one injection aperture (27) initially parallel to the longitudinal valve axis. The plate (22) is then plastically deformed at its central region (29) containing the injection apertures (27), by deep drawing, so that the injection apertures (27) are inclined in relation to the longitudinal valve axis (2) and are of a truncated conical shape, increasing in size in the direction of flow. This provides good preparation and high flow stability of the stream of medium provided through the at least one injection aperture (27). The perforated injection plate is especially suitable for injection values of fuel injection devices in internal combustion engines.
