Patent DE-3205575-A1 (DE)
Title: Control unit for an electrical apparatus
Inventor: GOLDBACH GERHARD ING GRAD
IPC: H01H3/04
Filed: 1982-02-17
Abstract: In a control unit for an electrical apparatus, for example a speed control installation, the operating parts (11) are of L-shaped construction and project with a pressure piece (9) through in each case one housing opening (10) in the control unit. Located on one limb (12) of each operating part (11) is a latch projection (14) which projects into a catch (15) of a side wall of the housing (1) of the control unit. A guide projection (18) is guided from the front end wall (2) of the control unit through an opening guide in the other limb (13) of the operating part (11), with play. The guide projection prevents the operating part (11) with its latch projection (14) being able to move out of the catch (15). Conversely, the latch projection (14) with the catch (15) prevents the operating part (11) sliding into the interior of the control unit and hence being able to detach itself from the guide projection (18). <IMAGE>

Title: Flexible supporting foot for a walking aid, especially for crutches
Inventor: FRANK XAVER
IPC: A61H3/02
Filed: 1982-03-30
Abstract: The invention relates to a support foot for walking aids, especially for crutches, which have a flexible floor-contact body. The floor-contact body has a supporting block as an elastomeric sole which is fixed to a support plate which is anchored to the support pipe of the crutch via an articulated device preferably having three degrees of freedom. This new design succeeds in imparting the necessary range of movement, predetermined by the anatomy of the elbow and wrist, to the crutch, while providing optimum contact between the sole and the floor throughout the motion sequence, force transmission from the body of the disabled individual to the ground always taking place over the entire sole support. As a result, the disabled individual can move absolutely safely even in the most difficult terrain, quick refitting of the walking aid being possible by means of appropriate technical engineering measures appropriate for disabled individuals.

Title: Carriageway heating system supplied with terrestrial heat
Inventor: HURICH WOLFGANG
IPC: E01C11/26
Filed: 1982-05-07
Abstract: The invention relates to a carriageway heating system supplied with terrestrial heat, in which the horizontally running heat-exchanger pipes are laid in the carriageway paving in such a way as to cover an area and transmit heat; these pipes are assigned a plurality of heat-conveying systems which in each case extend, in the region beside the carriageway, into the depths of the earth and are connected to the earth there in such a way as to transmit heat. Owing to a forced-circulation fluid or water circuit, the heat-conveying systems permit heat transmission in both directions with a small temperature difference and at low temperature. The circulation can also be stopped easily, so that heat conveyance can also be prevented. The water circuit is relatively insensitive and can be assembled in situ at the site, so that bulky and unwieldy preassembled heating-pipe systems can be avoided. To meet peak requirements of heat at times of particularly unfavourable weather conditions and possibly also for rapid thermal recharging of the earth, an additional heating means is arranged close to the surface and can be formed as an electric resistance heating or, for example, by a sewer.

Patent DE-3310461-A1 (DE)
Title: Method and circuit arrangement for generating pulses
Inventor: KUNZE DIETER ING GRAD
IPC: H03K3/017
Filed: 1983-03-23
Abstract: The method for generating pulses with a constant width and adjustable phase angles and a circuit arrangement to carry out the method use an approximately ramp-type signal, by means of which a trailing edge is triggered for a pulse if the signal has changed by a specific amount since the leading edge of the pulse. To reduce errors in the duration of the generated pulses due to deviations in the pattern of the approximately ramp-type signal, said signal is interrupted in the period between the leading edge and the trailing edge of each pulse, during a time interval whose length is precisely defined by a constant-frequency clock signal, and is resumed at the end of the time interval with a value which corresponds to the value at the beginning of the time interval, and the duration for a change in the ramp-type signal is significantly shorter by the specific amount than the time interval of the interruption. <IMAGE>
Patent DE-3312641-A1 (DE)
Title: Circuit arrangement for transmitting communication signals which are balanced relative to a reference potential
Inventor: STEFFEN FRANK ING
IPC: H04B3/30
Filed: 1983-04-08
Abstract: A circuit arrangement is specified, by means of which a useful signal which is balanced relative to a reference potential (e.g. earth potential), can be transmitted in a circuit constructed to be balanced relative to said reference potential, and, at the same time, unbalanced disturbing signals referred to the reference potential can be suppressed. For this purpose, positive impedances (23 and 24) which effect attenuation of the disturbing signals, are connected between the conductors (a and b) of the balanced circuit and the reference potential. The attenuation of the useful signal which is balanced relative to the reference potential which is likewise caused by the positive impedances is compensated for by inserting a negative impedance (-Z) between the conductors (a, b), with the result that the useful signal is maintained unattenuated. <IMAGE>
