Patent DE-3040316-A1 (DE)
Inventor: FLEISSNER HORST ING GRAD
IPC: G01R17/00
Filed: 1980-10-25
Abstract: A method and device for the contactless measuring of direct and alternating current, in particular current instantaneous values, by using a magnetic circuit having an air slot and a magnetic field dependent resistor through which a control current flows and a winding through which a measuring current flows. In order to provide a large measuring speed for picking up a rapid instantaneous value, for example, generated high current peaks, at least a further winding is mounted on the magnetic circuit, the voltage drops on the magnetic field dependent resistor are picked up and stored at the peak values or other typical values of the current to be measured. After completing the measuring current, the current in the equivalent current winding is increased and the already stored voltages corresponding to the measuring current are compared consecutively with the voltage drops on magnetic field depending resistor, corresponding to the increase in the amount in the equivalent current winding. At the same voltage values, the instantaneous current is determined by multiplying in the current in equivalent current winding by the winding number.

Patent DE-3101764-A1 (DE)
Title: Foot treatment device with air pump and vibration
Inventor: FRENKEL WALTER
IPC: A61H33/02
Filed: 1981-01-21
Abstract: The invention relates to a foot treatment device with air pump and vibration. On the underside of the base of the tub housing (1) (see drawing) there is securely arranged the vibration pump unit (2) consisting of a motor part and a pump part. In a preferred solution, the motor part is designed as a motor with a wobble weight, whose motor shaft drives a pump. A second solution proposes an oscillating armature drive, which activates a diaphragm pump. In both cases the vibration pump unit (2) generates both compressed air and vibrational movements, which are reinforced by the tub housing being capable of vibrating itself and are passed into the bath water (5). The compressed air is conveyed through a distributor system to the air outlet nozzles (3), which atomise it into the bath water (5). Vibrational movements and fine bubbles act on the feet of the person using the bath and lead to an increase in blood circulation, with flushing of tissue debris and transportation of oxygen and nutrients. In addition, internal organs are favourably affected via the foot reflex zones. <IMAGE>

Title: Operating device for a momentary-contact limit switch
Inventor: RITTHAMMER GUENTER
IPC: H01H21/28
Filed: 1981-02-10
Abstract: The invention relates to an operating device for a momentary-contact limit switch having a housing (1, 3) for accommodating a switching shaft (2) which can rotate as a result of the operation. In order to convert the rotary movement into a linear movement which acts on a switching plunger (4) in the operating device, the switching shaft (2) is provided with a flat (18). The flat (18) interacts during rotation of the switching shaft with the end surfaces (13, 15) of a switching plunger (4) and of a bush (7) which is guided displaceably against the force of a compression spring (11). The structural unit, which consists of the switching plunger (4), bush (7), mating bush (8) and compression spring (11), can be guided in the housing offset through 90 DEG  in each case so that the momentary-contact limit switch can be given different functions depending on the effective interaction between the flat (18) and the end surfaces (13 and 15). A web (17) which is integrally formed on the end surface (13) is used to limit the rotation angle of the switching shaft (2), which web (17) runs at right angles to the separating line of the overall end surface, half the width of the web extends in its longitudinal extent beyond the centre of the overall end surface, and its height extends into the plane of the end surface of the switching plunger (4). This results in rotation-angle limiting stops for the switching shaft (2), virtually without any additional parts. <IMAGE>

Title: Device for connecting two or more support section segments placed one inside the other for the underground sliding support system
Inventor: PREDL BRUNO
IPC: E21D11/22
Filed: 1982-01-30
Abstract: Devices for connecting two or more support section segments placed one inside the other for the underground sliding support system, which devices essentially consist of clamping bolts and straps, are recovered as support material from abandoned roadways or roadways to be abandoned. In practice, it is very difficult to release the strap connections on support section segments under pressure, since the force of the clamping within the connected support section segments is often so great that the thread turns between the nuts and the hook bolts usually used tear during the releasing and the nuts are thrown off at high speed towards the personnel underneath and constitute an accident hazard. In order to substantially reduce this accident hazard and in order to avoid laborious and time-consuming work with withdrawal aids, it is proposed that the strap be formed from two strap halves, and that the connecting parts of the strap halves be frictionally and releasably connected to one another by at least one transversely running connecting element, preferably a screw bolt.
