Patent DE-3810358-A1 (DE)
Inventor: FREGIEN GERT DIPL ING
IPC: H03K17/73
Filed: 1988-03-26
Abstract: In this method for controlling a gate-turn-off thyristor (1), the turn-off process occurs as usual by impressing a negative gate current (iG). To ensure improved utilisation of the gate-turn-off thyristor and of the driving driver stage (2), it is proposed to lower the negative driver voltage (UGKX) to a smaller value as soon as the anode current (iA) has dropped, that is to say as soon as the storage time (ts) has finished. The lowering can be effected in one step, in several steps or continuously after a delaying time function. The negative driver voltage is preferably lowered to a value of between 4V and 7V. The gate-cathode voltage (UGK) can be used for determining the precise time (t3) for lowering the voltage. The proposed voltage lowering reduces the power dissipation converted into heat in the thyristor which results in a distinctly reduced gate control power (PSt) and driver stage power (PTs). <IMAGE>
Patent DE-3810639-A1 (DE)
Inventor: THORWIRTH GUENTER DR
IPC: G02B5/00
Filed: 1988-03-29
Abstract: A microscope arrangement for analyzing input objects (5) visually and optoelectronically is suitable for the automatic classification of objects included in microscope preparations. The input object (5) is image enlarged for visual viewing in the usual way. However, a subdivided flat light emitter or an illuminated diaphragm (3) of variable shape disposed in front of the input object (5) in an aperture stop plane, is imaged onto an optoelectronic single detector (10) for an optoelectronic evaluation on the basis of an incoherent zone-sampling Fourier analysis. The quantity of incident light impinging upon the single detector (10) delivers a measured value which is determined by the radiating zone (19) of the subdivided flat light emitter or of the illuminated diaphragm (3) of variable shape and by the input object (5). When using different radiating zones (19) a number of measurements will form a series permitting an object classification. <IMAGE>

Title: Regulating speeds in extruder layout - by festooning extrusion between 2 conveyors and regulating one conveyor speed by difference between actual and target heights of sag
Inventor: EYSELEIN GERT DIPL ING
IPC: B29C48/92
Filed: 1989-12-13
Abstract: The conveyor speed in one part of equipment extruding elastomers and/or polymers is regulated in accordance with the speed of another part; the extrusion is festooned between the two parts concerned and the amt. of sag is used to control the input or output speed, the sag being measured by a sensor. The actual sag produces a signal from a sensor positioned above the lowest point of the festoon; another signal is similarly produced from a sensor positioned elsewhere; the difference between the two signals is used to regulate the drive, and the second sensor is set at a height above the material so that both signals are equal when the festoon has the desired height. ADVANTAGE - The method uses simple means for control. It does not produce adverse effects on the extrusion, nor undesirable variations in the surface finish of the extrusion (or any other physical property).
