Patent DE-3724121-A1 (DE)
Title: Cellular wheel sluice
Inventor: SCHNIEDER HEINZ
IPC: B65G53/46
Filed: 1987-07-21
Abstract: In the housing (1') of a cellular wheel sluice, a clearing paddle (3) is rotatably arranged on an axis (7) parallel to the axis of rotation (6) of the cellular wheel (2) in such a manner that, during its rotation, it dips into a cell (21), sweeps over the cell bottom with a stripper (32) and displaces material to be metered, which is adhering to cell walls, from the cell chamber into the outlet (9'). The stripper is constructed so as to be flexible so that it can adapt to the shape of the cell surfaces over which it sweeps. The clearing paddle (3) is driven at several times the rotational speed of the cellular wheel in such a manner that, during the clearing phase, its movement as it dips into a cell is directed counter to the movement of the cell. <IMAGE>

Patent DE-3821705-A1 (DE)
Title: Method for reducing the smear effect in a video camera operating according to the frame transfer principle
Inventor: HEINEMANN GERHARD DIPL ING
IPC: H04N5/3725
Filed: 1988-06-28
Abstract: Known video cameras have an image pickup with a comparatively high number of effective pixels. The aim of the method is to permit smear-reduced images illuminated at high speed to be picked up, preferably in conjunction with an image processing system. The analog output signal of the image pickup is digitised in an analog/digital converter. The fraction of the output signal which corresponds to the smear effect is determined in an arithmetic unit and subtracted pixel by pixel from the digitised output signal of the image pickup in such a way as to produce the true value of the pixel of a column from the difference of the actually received distorted value, as well as a product of the sum of the true values of the preceding pixels of this column and of a factor k. The factor k is determined from the transport time of an image from the image area into the memory area of the image pickup divided by the product of the integration time of an image and the line number. The method is preferably intended for carrying out precise optical measuring and detecting tasks. <IMAGE>

Patent DE-3836274-A1 (DE)
Title: Power converter for two current directions and method for its operation
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M7/757
Filed: 1988-10-25
Abstract: This power converter for two current directions is used for coupling a three-phase mains to a DC voltage network at an approximately constant voltage, with flow of energy being possible in both directions. For this purpose, the power converter has a rectifier (B1) and an invertor (B2), the AC-voltage sides of which are in each case directly connected to the three-phase terminals (1, 2, 3) of the three-phase mains. As opposed to an all-pole, direct, DC-voltage side antiparallel connection, the rectifier (B1) and the invertor (B2) are directly connected together on the DC-voltage side by only one pole, whereas the other sides are connected together via an electronic power switch (S). This switch (S) interacts with a diode (D) and a smoothing coil (L) in feedback operation as a step-down controller, while the invertor (B2) is simultaneously operated with a fixed maximum triggering delay angle ( alpha  max). In supply operation, the invertor (B2) and the power switch (S) are inactive. Drive-regulator devices, for example, may be connected to the DC-voltage network supplied using such a power convertor, which devices take in energy during drive operation and supply energy during braking operation. <IMAGE>

Title: Cleaning water - contaminated with halogenated hydrocarbon(s), esp. per-chloroethylene, by passing through sedimentation tank and activated carbon filter
Inventor: UHRNER HEINZ DIETER
IPC: C02F1/28
Filed: 1989-04-19
Abstract: The water is led continuously through a sedimentation separator at a temp. of not more than 25 deg. C and is freed from un-dissolved halogenated hydrocarbons. It then enters a collecting vessel, and quantities of the water are drawn from this vessel at adjustable time intervals and are passed to the activated carbon filter. A corresp. volume of water is at the same time withdrawn from the filter without mixing with the incoming water. Each transfer of water to the filter consists of a quantity of water which is not more than twenty percent of the volume of the filter. USE/ADVANTAGE - Deals with cleaning of water contaminated with halogenated hydrocarbons, esp. perchloroethylene such as is produced in the chemical cleaning of textiles. Water cannot be dispsoed of normally unless the concn. of the contaent is reduced to less than 0.1 . The process proposed achieves the required purification using a simple construction and can operate successfully in conditions of widely varying water flow rate and deg. of contamination..

Inventor: KLETSCH STEFAN
IPC: B21D55/00
Filed: 1989-08-03
Abstract: The punch press will usually be under CNC control.  The utility of the machine will be largely determined by the number of punches that can be selected, and the purpose of the invention is to pack as many punches as possible, typically 13 into an area of 270 x 170 mm, into the punch head.

In the worktable is a matrix-blocks (25) with bottom dies (27) corresponding to the punches (20). Each cylinder has its own inlet (29, 30) for pressurised oil on the working stroke, but space is saved by providing only a general inlet (33) to the cylinder block for the return stroke. A light beam monitoring system ensures that punches have returned. USE/ADVANTAGE - Simple, low-cost system. Component parts can quickly be changed to suit different classes of work.
