Patent DE-3303598-A1 (DE)
Title: Hydraulic system
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F15B11/08
Filed: 1983-02-03
Abstract: The invention proposes a hydraulic system in which determination and correction of the zero error and of the change in sensitivity at a pressure sensor (18) is performed in a simple manner. By means of a directional control valve (16), the pressure sensor (18) can be connected to a pressure space (13) or a tank (11). When connected to the tank (11), the pressure sensor (18) is relieved and its instantaneous measurement signal then corresponds to the respective measuring error. The measured value can thus be corrected by subtraction of this measuring error. If, on the other hand, the pressure sensor (18) is connected to a reference pressure corresponding to the nominal pressure, it is possible in addition to correct the sensitivity of the pressure sensor (18). <IMAGE>

Title: Interferometric arrangement for optoelectric distance measurement
Inventor: SALEWSKI KLAUS-DIETER DIPL PHY
IPC: G01B9/02
Filed: 1983-08-10
Abstract: The invention entitled "interferometric arrangement for optoelectric distance measurement" relates to the field of optoelectric distance measurement. The aim of the invention is to develop a distance-measuring device which can be achieved by modifying known interferometric laser position-measuring systems. The object is achieved by measuring the interferometer distance by means not of a single laser frequency but of light from a double-mode laser having an orthogonal polarisation orientation of two beam components. After interference has occurred between the measurement and reference beams, the interference signals corresponding to the two laser frequencies are separated by means of polarisation splitters, and directed on to separate optoelectric transducer units. Simultaneous electronic storage of the signals is performed with short memory-input times, in which the properties of the transirradiated optical medium can be regarded as quasi-constant. The measured values are fed to a computing unit for determining the phase angles of the interference signals corresponding to the two laser modes. The phase difference is proportional to the distance. The use of a plurality of laser light sources, whose mode spacing differs through slight variations in the laser mirror separations, permits unambiguous determination of distance over relatively large process ranges by combining the successively determined values.

Title: Method and device for checking for double layers in sheet processing
Inventor: BERNHARDT REINHOLD DR RER NAT
IPC: B65H7/12
Filed: 1983-12-12
Abstract: The invention relates to a method and a device for checking for double layers in automatic sheet processing. It is the aim of the invention to prevent double and multiple layers from being processed. The invention achieves the object of improving the checking reliability of previous capacitive devices, particularly of eliminating the interfering influence of machine vibrations. The essence of the invention consists in that when sheets are supplied in scale-like overlap, sheet overlap boundaries are scanned by means of two high-frequency-fed plate-shaped sensing capacitors, the high-frequency pulses are amplified and rectified with reference to phase, one of two storage capacitors is charged up in proportion to pulse amplitude depending on the pulse polarity and their voltage sum is evaluated by a threshold switch. The sensing capacitors, which are in each case mechanically coupled in pairs, are arranged behind one another in the transport direction so that the overlap boundaries scanned in each case pass through the sensing capacitors at the minimum distance of one capacitor plate length. The invention can be used in printing and packaging machines. Figure 1 shows the invention most characteristically. <IMAGE>

Title: Apparatus for bending the edges of metal sheets
Inventor: OSTROWSKI OSWALD
IPC: B21D19/02
Filed: 1984-01-10
Abstract: The invention relates to an apparatus for bending the edges of metal sheets by means of a machine power-operated bending head which can be guided along parallel to the edge. Bending is carried out, with the forming tools stationary and pressed against the edge of the sheet, by pulling the bending head along the edge of the sheet. Appropriate power drives must therefore be provided for the forming tools, for example hydraulic cylinders, which permit the transfer movements of the forming tools at the beginning and end of a bending operation and are capable of holding the forming tools continuously in the closed position during the bending operation. During forming involving pulling, high pulling forces acting on the workpiece have to be overcome in the drawing direction. Forming forces orthogonal to the drawing direction furthermore occur and these must be counteracted by guiding forces. In order to accept the pulling and guiding forces, the workpiece is secured, at least in the region of the edge, on a robust guide frame following the same course as the edge of the sheet. The apparatus is virtually silent in operation and smooth workpiece surfaces are obtained at a high work rate.
