Patent DE-3606496-A1 (DE)
Title: Ultrasound-operated apparatus with cooling element for humidifying air
IPC: B05B17/06
Filed: 1986-02-28
Abstract: Ultrasound-operated apparatuses for humidifying air have, in addition to a water reservoir, in principle an ultrasound unit which consists of a cooling element (12), an ultrasound energy converter (13) and a control unit (14) which controls the latter, the cooling element (12) being arranged in a wall of the water reservoir (11) and serving to absorb the dissipated heat produced by the control unit during operation and deliver it to the environment. Hitherto, a separate cooling element (12) was necessary for each ultrasound unit, which led to considerable space and assembly problems, particularly in the case of an increase in output of the apparatus. To overcome this disadvantage, it is therefore proposed to provide the water reservoir (11) with a plurality of openings (15, 16) serving to accommodate respective ultrasound energy converters (13). For a plurality of ultrasound energy units to be provided in the water reservoir (11), however, only a single cooling element (12) is provided, to which, for the purpose of increasing the capacity, only a corresponding number of control units (14) for the associated ultrasound energy converter need to be attached. <IMAGE>

Title: Reprocessing method for spent oil and reprocessing plant
Inventor: FARKAS LASZLO TIBOR DR ING
IPC: C02F1/52
Filed: 1986-07-02
Abstract: For reprocessing spent oil contaminated with PCB and dirt constituents, a method and a plant are used in which the spent oil is first processed with water to give an emulsion which is then subsequently broken by addition of a preliminary breaking agent, so that the free oil can be scooped off and passed to incineration. This scooping is carried out in a way which minimises the water content of the spent oil, so that the correspondingly purified spent oil can then be safely disposed of by incineration. The water is circulated and intensively purified, so that the costs thus incurred can also be kept within limits. <IMAGE>

Title: Device for setting a torque limitation on a screwdriver
Inventor: STREUBEL JOACHIM
IPC: B25B23/143
Filed: 1987-02-16
Abstract: The device for setting a torque limitation on a screwdriver is applied when the same tool is also to be used for loosening the screwed connection which has been established by it. The object of providing a universally usable screwdriver with a greater torque to be overcome in defined manner and a greater torque to be overcome in undefined manner is achieved according to the invention by the fact that the transmission balls, on the one hand, are let into receiving bores of the transmission body and, on the other hand, engage in a counter-receptacle which is bevelled in the tightening direction. The pressure on the transmission balls which defines the torque is produced by a spring element which is to be tensioned via a threaded bolt. During tightening, the transmission balls run out of the bevelled counter-receptacles after the set torque has been reached, and the torque cannot be exceeded. In the direction opposite the tightening direction, there is no bevel on the counter-receptacles, so that by applying a greater torque using the same tool the screwed connection can be loosened. <IMAGE>

Title: Automatic adjustment of the evaluation/measurement signal level in the case of corpuscular beam measuring methods
Inventor: BRUST HANS-DETLEF
IPC: G01R31/306
Filed: 1987-09-01
Abstract: In a first method and in a device therefor, instead of a constant evaluation level use is made of a variable reference level which is automatically matched to the changing circumstances. In order to fix the evaluation level, the positive and negative peak values of the measurement signal (m(t)) have to be determined. The determined peak values are then added in an adder (ADD) and fed to a voltage divider (SpV), which places the reference level in the middle between the minimum and maximum of the measurement signal. This evaluation level is then fed as reference value to a comparator (KO1) of the corpuscular beam measuring arrangement. In a second method and a device suitable therefor, the measurement signal (m(t)) itself is varied instead of the evaluation level. It is necessary for this purpose to vary the peak-to-peak value and the offset of the measurement signal (m(t)) with the evaluation level held constant. The measurement signal is initially displaced such that it is located symmetrically about the zero point. Subsequently, the peak-to-peak value of the offset-compensated measurement signal is held constant. <IMAGE>

Title: Electronic dance floor
Inventor: RIENKS GERD
IPC: G09B19/00
Filed: 1987-09-14
Abstract: Dancers would like to be able to learn new dances more quickly and independently. Dance instructors are not always available and many people lack the courage to appear clumsy in front of others. Dancing lessons take place too seldom and are in addition often not within easy reach. An electronic dance floor solves the problem by means of a programmable controller, by means of which all dances can be called up, which are then displayed as step sequences on the dance floor (large-screen monitor). In this way, dancing can be quickly learnt because, in addition, tempo and sequences can be increased up to whole formation dancing groups with the correct division of the room.
