IPC: B23P21/00
Filed: 1985-12-18
Granted: 1989-04-13
Abstract: In the automatic equipping of, for example, printed circuit boards with components, the problem of the unknown position of the component legs occurs. According to the invention, the positions of the component legs in a component picked up by a gripper are measured by a sensor immediately before plug-in. This sensor is essentially composed of two independently horizontally movable perforated plates, each including an infrared emitting diode which emits onto a stationary position photodiode situated therebelow. The measured result can be employed for the positional correction or for the rejection or acceptance of the component.

Abstract: A method for controlling a converter in an HVDC power transmission system and a converter with appropriate control means for carrying out said method. The current regulator influences the control angle of the converter in dependence on the difference (I0-Id- DELTA I) between, on the one hand, the measured current (Id) and, on the other hand, the current order signal (I0) decreased by a current margin value ( DELTA I), controlling the converter with a control angle which is dependent on the one hand, on a proportional component being linear proportional to said difference and, on the other hand, on an integral component corresponding to the time integral of said difference. The current regulator has a proportional regulator part (PR) and an integrating regulator part (INT1). The output signal of the integrating regulator part is limited in the upward direction to a value corresponding to a maximum value of the control angle of the converter. The output signals from the integrating and the proportional regulator part are added to form the output signal of the current regulator. The limiting value of the integrating regulator part is calculated by a calculating circuit as a function of the current order and the ideal direct voltage of the converter. The calculation is made by determining the control angle at which, at a load current equal to the current order, the extinction angle becomes equal to the smallest permissible turnoff angle. From this angle there is then subtracted the output of the proportional unit at a current equal to the current order, and the result constitutes the limiting value for the integrating regulator part.

Abstract: A diaphragm compressor has a compressor housing (1) comprising a bottom section (2) and an upper section (3). A flexible diaphragm (5) is inserted between a bottom diaphragm disc (7) and an upper diaphragm disc (8) and projects laterally. The diaphragm (5) is firmly clamped by its edge (6) between the bottom section (2) and upper section (3) of the housing. A connecting rod (12) produces a lifting motion of the diaphragm (5) and the adjacent diaphragm discs (7, 8). This compresses a medium in a working chamber (15). Below the diaphragm (5) is a piston chamber (18) in the lower section (2) of the housing. The diameter of the working chamber (15) formed in the upper section (3) of the housing has a greater diameter than the piston chamber (18). The diameter of the bottom diaphragm disc (7) is distinctly smaller than the diameter of the piston chamber (18). As a result an annular gap (20) is left between the bottom diaphragm disc (7) and the opposing inside wall of the bottom section (2) of the housing. The diameter of the upper diaphragm disc (8) is thereby at least equal to that of the bottom diaphragm disc (7). The clearance (19) produced at the top dead centre between the upper section (3) of the housing, diaphragm (5) and upper diaphragm disc (8) takes the form of an annular duct and is greatly offset outward in a radial direction in the area of the edge (6) of the diaphragm (5). The proposed diaphragm compressor is outstanding by virtue of an improved characteristic behaviour. The increase in pressure given a reduction in the volume flow occurs much more slowly; the fluctuation in the maximum pressure which can be generated in the working chamber (15) is much less. <IMAGE>

Abstract: An electromagnetic survey method for geophysical exploration, in which the variations in the earth's magnetic field are measured in two, non-parallel directions at one point in the survey area. Simultaneously, the variations in the earth's electrical field parallel to the survey line are measured at a number of points along the survey line. These measured variations are transformed to the frequency domain, and then the horizontal component of the magnetic field orthogonal to the direction of the measured electrical field is calculated. The impedance at each measurement point on the survey line is calculated as a function of frequency, and weighted averages of the impedances for predetermined frequencies using a zero phase length weight function corresponding to a low pass filter applied to the electric field are used to calculate the subsurface conductivity distribution.

Title: Vulcanising envelope for repairing and recapping tyres
Inventor: SCHMERMBECK DIETER
IPC: B29D30/54

Granted: 1989-08-24
Abstract: The vulcanization sleeve described is designed to be air-tight at least in the tyre processing region to allow evacuation of air and gaz bubbles from the space between the sleeve and the tyre or the tread or tread cap, and it covers the processing region during vulcanization in an autoclave. The problem is to find a solution which while maintaining the advantages of the so-called cold process enables during vulcanization a considerable increase in the longevity of the sleeves, a simplification in handling and in particular the application by vulcanization of treads in the form of sections of otherwise endless pieces of tread. This is achieved by the fact that the vulcanization sleeve is made of a plastic foil (6) of thermoplastic polyurethane, and in the event of a partial covering of the tyre, this sleeve is provided possibly with a sealing ring (7).
