Patent DE-4224884-A1 (DE)
Inventor: LINDERMANN WALTER
IPC: H01M10/54
Filed: 1992-07-28
Abstract: The invention relates to a process for the recovery of raw materials from presorted collected waste, especially scrap electrochemical batteries and accumulators in which the scrap (10) is first mechanically prepared and divided into coarse and fine fractions (15, 16) which are further processed separately. Materials to be recovered are extracted by dissolution in steps by a first and a second solvent in a wet chemical preparation process from the fine fraction and then recovered individually from the two solutions.

Title: Rotation angle, revolution rate and rotation direction measurement - using analogue and digital encoder with differentiation and integration of signals.
Inventor: CHIKAZAWA YOSHIHARU
IPC: G01P13/04
Filed: 1992-09-30
Abstract: The method involves using a combination rotation encoding disc having a digital and an analogue code region. At least one sensing element continuously increasing in the rotation direction has at least one abrupt transition. The corresp. detection signal is an analogue rotation angle measurement signal. The angle measurement signal is differentiated to form a signal corresp. to the angular speed and indicating the rotation direction. The rotation rate is derived by integrating the number of pulses corresp. to revolutions over a time period. USE/ADVANTAGE - For rotation parameter measurement using rotation encoder, e.g. for CD's. Advantages of digital, or incremental, and analogue measurement techniques and equipment are combined in simultaneous measurement of rotation angle, rate and direction.

Title: Pharmaceutical speciality for appetite suppression and digestion promotion in fasting treatments
Inventor: MAIER KARL-HEINZ DR
IPC: A61K33/04
Filed: 1993-03-23
Abstract: Pharmaceutical speciality for suppressing the appetite and promoting the digestion: The combination of the active substances sodium sulphate, medicinal charcoal and gum arabic when used in suitable dosage confers on the body a feeling of repletion despite reduced food intake in fasting treatments. This is achieved by the action of the sodium sulphate. The usual side effect of excessively increased bowel peristalsis with diarrhoea is prevented by the simultaneous intake of medicinal charcoal and gum arabic in suitable gelatin capsules. Medicinal charcoal and gum arabic act to inhibit peristalsis.
Patent DE-4311628-A1 (DE)
Inventor: BODZAK STANISLAW DIPL ING DR
IPC: F02M57/02
Filed: 1993-04-08
Abstract: A fuel injection pump for an internal combustion engine has a pump piston (1) which is axially guided in a cylindrical bore (3) and defines therewith a pump working chamber (9). The pump piston is divided into a body part (15) and a head part (17) by an annular groove (13) in the outer surface. In order to avoid "piston scores" in the region of the head part (17), the head is either uniformly reduced in diameter relative to the body part (15) or is guided in the cylindrical bore (3) with slight play relative to the wall thereof only along lines which are obtained by appropriate shaping of the head. In separate embodiments the head is given an elliptical cross-sectional shape or a convex shape in side elevation. Such shapes provide reliable axial guidance of the piston head (17) while increasing the clearance between the piston head (17) and the wall of the cylindrical bore (3) in the endangered regions accommodating the control edges (23). <IMAGE>

IPC: B27N5/00
Filed: 1993-12-15
Abstract: The mat-like semi-finished material (5,9) is formed from several layers, like a sliding mat.

Title: Vessel, using which electrical current can be drawn primarily from biological substances
Inventor: SCHNORR WOLFGANG
IPC: H01M50/121
Filed: 1993-12-16
Abstract: With the aid of the vessel, it is intended to employ biological substances for obtaining current, in order to reduce materials which pollute (load) the environment, and battery waste. The electrodes of the vessel, which are in the form of coils or grid surfaces, can be fitted into each other, combined to form lattices and fitted into sponges in which there may also be granules. The vessel may be coated with a piezoelectric material, as may the electrodes in part. When using the vessel as a plant container, current may be obtained from the change in weight of the vessel, the incident radiation or the pressure of the plants. Electricity is intended to be stored in the plant container substantially by means of a dried culture medium between two metal plates. A higher drawn current is intended to be obtained by a special plant granulate, consisting of cellulose fibres, coal and metal powder or a plant activation by pulsed magnetic fields or by moving the electrolyte contained in the vessel, using microorganisms or a rotor in conjunction with wind or air flow, the vessel or a rotor which moves the electrolyte or rotates around the vessel being coated with magnets, or by the action of light when using a ferromagnetic electrolyte. The vessel can be used for obtaining current from biological waste products, from plant containers and for obtaining a biogas, as rechargeable battery and ... Original abstract incomplete.

Title: Hydraulic shock absorber with damping-force control
Inventor: NAKADATE TAKAO
IPC: B60G17/015
Filed: 1994-03-09
Abstract: A cylinder (7) with a hydraulic fluid sealed in it is provided with a piston (8) having a piston rod (9) connected to it. The piston rod (9) is provided with a bypass (B) for producing a relatively small damping force. The aperture area of the bypass (B) is controlled by varying the area of outflows, formed by guide openings (21 and 22) and shutter openings (24 and 25) by rotating a shutter (23) in order to thereby change the damping-force characteristics. Auxiliary openings (34 and 35) are provided in order to open into the guide openings (21 and 22). The hydraulic fluid ejected in the shutters (23) from the outflows, formed by the guide openings (21 and 22) and the shutter openings (24 and 25), is drained, to flow approximately perpendicularly to the direction of the sliding of the shutter (23) through the hydraulic fluid which is ejected from the auxiliary openings (34 and 35), in order to thereby reduce the hydrodynamic force which acts in the sliding direction of the shutter (23) and thus minimise the force which is required to actuate and hold the shutter (23). <IMAGE>
