Title: Electronic flash gun for producing partial quantities of light
Inventor: FOERSTER SIEGBERT DIPL ING
IPC: H05B41/30
Filed: 1987-10-01
Abstract: An electronic flash gun for producing different predetermined partial quantities of light has two flash tubes (1, 2), one (2) of which can be optionally switched off, a flash capacitor (6) whose charge can be discharged by means of the flash tubes (1, 2) for emitting flash light, a switching-off device (4) for terminating the discharge of the flash capacitor (6) after a switch-off signal has been received, a delay device (7) for generating said switch-off signal after a delay time, with respect to the start of the discharge, which delay time corresponds to the discharge period necessary for the selected partial quantity of light, and a setting device (11, 22) for selecting one of the predetermined partial quantities of light by setting a corresponding delay time. This electronic flash gun has a compensating circuit (8) which can be controlled by the voltage across the flash capacitor (6) and/or by switching the second flash tube (2) on or off and which compensates, by influencing the delay time, for the reduction in the emitted partial quantity of light relative to the predetermined partial quantity of light which is caused by a reduced voltage across the flash capacitor (6) and/or by switching on the second flash tube (2). <IMAGE>

Title: Frame-shaped diaphragm or spacing washer
Inventor: SCHNEIDER THOMAS
IPC: F16B43/00
Filed: 1987-10-02
Abstract: Diaphragm and spacing washers are used in industry for adapting and equalising distances. They consist of thin metal leaves. Different sizes must be produced and held in stock to match the part to be connected. In order to reduce the production and stock holding costs for diaphragm and spacing washers with different inside diameters, the invention envisages that at least two diaphragm and spacing washers (3) in each case be formed one inside the other by an integral metal sheet, being separated from one another by a circumferential slot (5) and connected to one another by at least one remaining web (7). The washers are suitable, in particular, for connecting pipes. <IMAGE>

Title: Switchable and adjustable thread tensioner
Inventor: ZITZEN WILHELM
IPC: B65H59/22
Filed: 1987-10-10
Abstract: The invention describes a method and a device for carrying out the method on switchable and adjustable thread tensioners having two brake plates, of which at least one brake plate is driven and one brake plate is pressed mechanically with spring force against the other brake plate, in order, on each thread tensioner, so as to generate an individual contact pressure of the respective pair of brake plates (2), to superpose a variable pressure force on the pressure set there. As a result, the thread tension can be controlled, as desired, in dependence of the diameter and/or weight of the bobbin (26, 26'), in the event of a thread break recorded by sensors (36, 38) or during the run-up of a winding drum (35) after a rectified thread break as well as at the start of a winding run. <IMAGE>

Title: Method of producing laser radiation at a high repetition rate in the infrared band, especially for uranium isotope separation
Inventor: JETTER HEINZ DR
IPC: B01D59/34
Filed: 1987-10-17
Abstract: The method works in particular with laser radiation wavelengths in the 16  mu m band, pulsed CO2 laser radiation being converted into the relevant wavelength band by stimulated Raman scattering in gaseous hydrogen in a refocusing multiple-reflection cavity. A continuously pumped CO2 low-pressure laser with emission extractable in pulses should be usable for this, the power level of which need not lie at the upper limits. According to the invention, in order to reduce the required pulse power of the CO2 laser, which is difficult to produce especially at a high repetition frequency, the emission pulses of a short-wavelength metal vapour laser are coupled simultaneously and colinearly with the CO2 laser pulses into the multiple-reflection cavity. In this case, the power of the metal vapour laser is selected such that the threshold for stimulated Raman scattering for the metal vapour laser light is reached in one of the first transits in the multiple-reflection cavity. The 16- mu m radiation produced through 4-photon mixing from the CO2 laser light is amplified in subsequent transit through the multiple-reflection cavity up to the power required for the technical application. Uranium isotope separation using lasers.

Patent DE-3821814-A1 (DE)
Title: Device for the transmission of signals between a rotating part and a spatially fixed part
Inventor: WENZL HEINZ DR
IPC: H04B10/00
Filed: 1988-06-29
Abstract: A description is given of a device for the transmission of optical signals between a rotating part and a spatially fixed part, optically coded signals being emitted via one or more light-emitting diodes on an inner ring consisting of transparent material, which is surrounded over a gap by an outer ring, likewise made of transparent material, in which at least one receiver is embedded. The optical signals are reflected inside the transmitter ring as well as the receiver ring and radiated across the gap from the transmitter ring into the receiver ring. They can therefore be received over a complete spatial angle independently of the relative position of transmitter and receiver. With the device according to the invention, the optical signals can therefore be transmitted both during mutual rotation of the parts and also when stationary.

Title: Arrangement for the measurement of the concentration of oil-water mixtures
Inventor: REUCKER KLAUS
IPC: G01N29/032
Filed: 1988-07-23
Abstract: The concentration of an oil-water mixture guided through a measuring chamber is intended to be measured continuously or periodically at short time intervals, an oil content in particular of 0 to 20%, preferably 0.5 to 10%, being intended to be exactly detectable. For this purpose, the measuring chamber is equipped with an ultrasonic transmitter and an ultrasonic receiver bounding a measuring path and, by means of an associated measuring arrangement, either the attenuation of the received ultrasonic signal in comparison with that yielded in the case of filling with pure water is measured or the alteration of the transit time of the signals in comparison with that yielded in the case of pure water is determined. In order to exclude cross-couplings of an ultrasonic transmitter and an ultrasonic receiver contained in a common measuring head, it is also expedient in this case to work pulse-wise and to sample the receiving arrangement only after the transmitted energy has fallen.
