Title: Acceleration pick-up
Inventor: DOBLER KLAUS DR ING
IPC: G01P15/105
Filed: 1983-12-08
Abstract: Acceleration pick-up having a sensor element which can be deflected essentially only in one direction of movement and has the form of a flexural vibrator clamped at one end, or of a spiral spring. The mechanical deformation upon the action of an acceleration or deceleration is measured by suitable distance-measuring methods or strain gauges; vibrations at natural frequencies, which give rise to corrupt measurement results, which vibrations can also occur with accelerations lasting only a short time, are damped by a mechanical stop due to the fact that the flexural vibrator cannot be deflected from the zero position except in the measurement direction. <IMAGE>

Patent DE-3415737-A1 (DE)
Title: Crutch with load display
IPC: A61H3/02
Filed: 1984-04-27
Abstract: During convalescence, patients with leg injuries usually use a pair of the known crutches with forearm supports. In order to exercise the injured leg they are frequently instructed to put weight on this leg in conjunction with the crutches but only to a weight expressed in kilogrammes. This leads to uncertainty and, depending on the mentality of the convalescent patient, to insufficient or excessive strain because assessment or measurement of the weight bearing upon the injured leg is impossible. The crutches with load display inform the patient with the injured leg at every step about the load on the crutches set in accordance with his body weight and the maximum load on his injured leg and thus simultaneously about the correct or excessive or insufficient load on his injured leg. With advancing convalescence and hence with increasing loadability of the leg, the load range of the crutches can be varied correspondingly.
Patent DE-3433709-A1 (DE)
Title: Automatic dispenser for video-film cassettes
Inventor: FOELKEL WILHELM DIPL PHYS DR
IPC: G07F11/32
Filed: 1984-09-14
Abstract: The machine serves preferably as a central component of an apparatus for automating the rental or sale of video-film cassettes and is tailored in technical terms to the particular requirements of this market, in that it allows a free view in the original of a relatively large number of cassettes which are offered for dispensing and which appear to the observer as being set up above and next to one another in a shelf-like manner and each one of which is held by tongues of a rearwardly pivotable carrier plate. Pushbutton release of a respective associated electromagnet causes the selected cassette to slide obliquely forwards and downwards to the outlet. Two plates inclined obliquely relative to one another have to be spread apart by the falling cassette before the outlet is reached in order to slow the falling speed. Instead of one particular cassette, a plurality can also be carried by the same respective tongues, in such a way that, by an appropriate choice of the length of the carrying tongue and by limiting the magnet lift, only the foremost cassette slides off and those located behind it shift forwards onto the vacant space as a result of spring pressure.

Patent DE-3447397-A1 (DE)
Title: Electrical pressure sensor
Inventor: ECKARDT DIETER DIPL ING
IPC: G01L17/00
Filed: 1984-12-24
Abstract: A pressure sensor (10) is proposed for producing electrical signals, having a membrane (13) which supports at least one sensor element (12a), can be deformed as a function of pressure and closes a reference-pressure chamber (19) towards a medium which is under pressure. Provided for leakage monitoring of the reference-pressure chamber (19) is a second membrane (25) which closes the reference-pressure chamber (19) towards a test pressure and which supports at least one test-sensor element (26a) which, in the event of a leakage in the reference-pressure chamber (19), emits a signal to a closed evaluation circuit, in order to indicate a defect. In this case, the pressure sensor can be constructed such that a large pressure difference acts on the second membrane when the reference-pressure chamber is pressure-tight, or the pressure difference on the membrane (25) occurs after a leakage in the reference-pressure chamber (19) (Figure 1).
