Title: Rendering ultrasonic image visible using separate transmitter crystal - to determine shape and depth of flaw in test specimen
Inventor: WILHELMS WALTER
IPC: G10K11/30
Filed: 1980-07-16
Abstract: Rendering an ultrasonic image of the inside of the material under test visible involves using a separate transmitter crystal with overall electrode for ultrasonic transmission. A separate ultrasonic received of low-ohmic piezo crystal, pref. hygroscopic sealed LiIO3, is used. Liquid crystals of p-pentylphenyl-2-chloro-4- (p-pentylbenzoyloxy)- benzoate and p-octylphenyl-2-chloro-4- (p-heptylbenzoyloxy)-benzoate respectively are used as optical transducer for the impulse sequence frequency and image shading. A liquid, the density-optical characteristic of which can be adjusted by its concn. or mixing, is also used. The cost is relatively low and no water bath is needed, making the equipment cheap and readily transportable. High resolution is possible and the shape and depth of flaws can be found accurately, since the image depth can be adjusted, without wall back-echo.

Title: Rapid wind for cine projector - has controlled phase to take up film loop and reduce torque shock
Inventor: ACKERMANN MANFRED
IPC: G03B1/54
Filed: 1980-11-06
Abstract: When the rapid drive is stopped a time delay circuit operates a braking sequence in which the motor torque is progressively reduced while the drive is braked. The film is held straight between the reels and no film loops are formed. The film loops are automatically formed prior to projection. The sprocket wheels for the film gate only engage the film at the end of the brake cycle. If the projector is switched to rapid wind, after projection, the film loops are first taken up and then rapid wind applied. Sudden tension forces are avoided and the film suffers no damage. The timing circuit's are simple RC loops or counters linked to the sprocket hole detectors.
Patent DE-3048466-A1 (DE)
Title: Workpiece force and/or displacement characteristic measurement - using initialisation force defining displacement sensor null point during mfr.
Inventor: KUMETH SIEGMUND
IPC: G01M99/00
Filed: 1980-12-22
Abstract: A method is for measuring the force and/or displacement characteristics of a part of a test object moving against a counter force. It is applicable to workpiece tolerance testing in industrial manufacturing facilities, and enables highly accurate measurement by eliminating errors caused by non-linearities, friction etc. The displacement sensor measures the displacement of the force sensor directly w.r.t. the reference surface. At the beginning of the procedure, the sensor is held against the moving element by an initial force not greater than the bias force on the moving element. The position of the sensor for which this initial force is achieved is used as the nill point for subsequent displacement measurements of the displacement measurement device w.r.t. the test object. Distance measurement is totally independent of force measurement.

Title: Profiled tape for releasable connections
Inventor: RENFTLE HANS ING GRAD
IPC: A44B18/00
Filed: 1981-04-01
Abstract: The invention relates to a profiled tape for releasable connections. The aim of the invention is to provide a flat connecting means for releasable connections, which means can easily be attached to many parts. The profiled tape provides a releasable connection which, in one direction, is defined in the plane and, in the other direction, can accommodate tolerances. The profiled tape can also be combined or correspondingly designed in such a way that the parts can be connected to one another in such a way that they can accommodate tolerances in one direction or in two directions in the plane. This profiled tape is simple and cost-effective to produce. According to the invention, the object is achieved in that a profiled tape has attachment possibilities, such as a self-adhesive coating on the non-profiled side, or a layer of adhesive applied retrospectively to the non-profiled side, or holes for screws or rivets, and has at least one profiled side with at least one elevation whose cross-section remains essentially the same over its entire length and has a recess at the base, at least on one side. <IMAGE>

Patent DE-3121088-A1 (DE)
Inventor: EILERS NORBERT DIPL PHYS
IPC: G08G1/09
Filed: 1981-05-27
Abstract: To improve reliability of recognition of an announcement recognition (AR) signal radiated by a transmitter upon broadcasting an announcement (e.g. traffic information, news, etc.), in the form of AM modulation of a 57 kHz auxiliary subcarrier, in which the subcarrier may also be modulated by other control signals, the subcarrier is filtered in the receiver, demodulated, and the degree of all modulations, regardless of frequency, on the subcarrier is sensed, and if the modulation changes significantly, for example rises from 60% modulation to 90% modulation (50% change), a switch (4) is activated which inhibits transmission of audio programs from an external source, such as a tape recorder (5), tuner tuned to another station, or the like, and reproduces the announcement being broadcast; termination of the AR signal, forming the AR modulation on the subcarrier, causes the switch to revert for reproduction of previously controlled audio information.

Title: Process and apparatus for charging pressure filtration plants with slurries
Inventor: MOEHRING HORST
IPC: B01D37/02
Filed: 1981-07-07
Abstract: To charge pressure filtration plants with slurries (sludges) it is proposed to withdraw the slurry from a slurry tank (11) by a displacement pump (3) and to feed it to the pressure filtration plant (6). On the suction side of the displacement pump, filter aid is added to the slurry with the help of through-flow mixers (1, 2) and, on the pressure side of the displacement pump (3), the conditioned slurry is conveyed into the pressure filtration plant (6) via a pressure chamber (5). In the pressure chamber (5), a compressed-air cushion is built up over the slurry by an air compressor (7), when the displacement pump (3) can no longer overcome the filter resistance of the pressure filtration plant (6), and, on reaching this filter pressure, is shut off from the pressure chamber and the pressure filter plant. The pressure in the compressed-air cushion is increased until the slurry is forced by the compressed air out of the pressure chamber into the pressure filtration plant. A large part of the water remaining in the filtration plant is finally expelled by depressurising the pressure chamber via the pressure filtration plant. <IMAGE>

Title: Nozzle arrangement in a device for drying vehicles
Inventor: GENTISCHER JOSEF ING GRAD
IPC: B05B1/00
Filed: 1981-07-22
Abstract: The invention relates to a nozzle arrangement, comprising a nozzle body (1) forming a cavity which can be supplied with air, and a slit part (3) which is connected to the nozzle body (1) and, in a device for drying vehicles, can be moved relative to the vehicle to be dried. The nozzle movement is controlled in a known manner by following the contours of the vehicle. In order to reduce the risk of damage should the nozzle arrangement, as it moves relative to the vehicle, collide therewith and to make the control of the nozzle movement easier and more reliable, the invention proposes that the nozzle body (1) be formed at least partly from a flexible, air-impermeable material. In a further development of the invention it is proposed that the cavity of the nozzle body (1) have a conical shape, the cross-sectional contour of the cavity and the width (b) of the slit of the slit part (3) being dimensioned such that the speed of flow of the air in the cavity is greater than zero and there is a positive pressure profile over the entire length of the slit part (3). As a result, the air emerges in an oblique direction out of the slit part. <IMAGE>
