Title: Regulating current of DC motor - comparing digital armature current actual value detected in cycle time not exceeding 0.2 ms with stipulated value
IPC: H02P7/28
Filed: 1992-02-25
Granted: 1993-04-08
Abstract: A method of current regulation for a d.c. motor operated via two converters in a back-to-back circuit without circular currents involves using a change-over device which activates one of the converters depending on the current direction in a core. The core current is sampled and compared with a demand value. The control error is used to regulate the control loop gain. When the current direction changes a safety period is imposed during which both converters are off. ADVANTAGE - Can be implemented with digital technology to achieve quasi-continuous control equivalent to that of analogue system.

Title: Catalytic hardening of sand mould elements - with two-stage sepn. and removal of amine(s) and solvents from exhaust air
Inventor: GUNTER KLAUS
IPC: B01D53/04
Filed: 1992-07-31
Granted: 1993-11-25
Abstract: Catalytic hardening of sand mould elements, in particular, cores made of resin-bonded sand, is concerned with recovery of amines used as catalysts in the form of gases or vapours mixed with air. Cleaning of the air/gas/vapour mixt. takes places in at least two stages, and includes the following steps: a) direct condensn. to remove fractions with a high boiling point by means of a low-temp. liq. circulation agent; b) gravity sepn. of the lighter solvent fractions from the water phase contg. amines and heavier solvent fractions; c) removal of the heavier solvent fractions and amines by means of a regenerable adsorption agent; d) condensn. of amines and the heavier solvent fractions from the desorbed gases, and their separation in a gravity separator. USE/ADVANTAGE - In mould core-making plants. In comparison with known alternatives, it is less costly (as a result of reduced plant and energy requirements).

Title: Water pipe leakage rate measuring method - using pressure characteristic for test vol. divided from interior of pipe by flexible foil
Inventor: SEPP GUNTHER DR
IPC: G01L11/02
Filed: 1992-10-02
Granted: 1994-01-13
Abstract: The leakage rate is measured for a drinking water or waste water pipe (1) with an internal pressure (pi) which is greater than the ambient pressure (pu)/t. A flexible foil (3) is attached to the inside wall of the pipe to define a sealed test vol. (5) within which the pressure is detected via a pressure sensor. The measured pressure over a defined time interval provides a pressure characteristic, evaluated to determine the leakage rate. Pref. the time over which the pressure within the test vol. remains approximately the same as the pipe internal pressure is measured, together with the time taken for it to drop to the ambient pressure level. ADVANTAGE - Determines leakage rate and position without interrupting pipe flow.

Title: Method and apparatus for removing the paint from painted plastic components
Inventor: RAUENSCHWENDER WALTER
IPC: B44D3/16
Filed: 1993-05-21
Granted: 1994-08-25
Abstract: In order to remove the paint from painted plastic components, especially from painted bumpers of motor vehicles, the granulated plastic particles are mixed with an aqueous paint-removing agent and the paint is then removed by rubbing of the plastic particles. Subsequently the mixture is stirred, with the addition of further paint-removing agents, and the aqueous paint removing agent is removed. The residual mixture of plastic parts and paint particles is then washed with water and the paint particles are separated off by centrifuging. A device suitable for implementing the process consists of a mixer with a fast-running mixing mechanism, a stirred vessel adjoining the latter and having a stirrer, and a screen-type centrifuge adjoining the stirred container.
