Patent DE-3151560-A1 (DE)
Title: Arrangement for automatically connecting a coupling part assigned to a vehicle and a stationary coupling part for an electrical connecting line, and a plug-in coupling for this
Inventor: LOEWENHOFF PETER DIPL ING
IPC: H01R13/453
Filed: 1981-12-28
Abstract: The invention relates to an arrangement for the automatic connection of a motor vehicle to one or more external electrical circuits, having a special plug-in coupling and a guide mechanism. When the vehicle approaches the arrangement, the connection is produced, and when the vehicle moves away the connection is released without a manual intervention being required. For this purpose, a special plug-in coupling is used which is protected against moisture and contamination, ensures the contact protection and is self-centring in a specific range. The guide mechanism which is also provided for this purpose automatically adjusts one plug-in coupling part with respect to the other when the vehicle approaches. The inaccuracy of this adjustment is compensated during the connection of the two plug-in coupling parts by means of their self-centring mode of operation.
Patent DE-3203964-A1 (DE)
Title: Device for heating (or cooling) rooms by means of a flowable heat transfer medium
Inventor: KORNER WILHELM FRIEDRICH
IPC: F24D3/10
Filed: 1982-02-05
Abstract: In a line bus (12) of a hot-water heating system with at least one forward-run line (24) and one return-run line (25), possibly also an added return-run line (69), there are connected in at the branching-off points for branch lines, in particular the connections for floor heating elements (27, 29, 31), branching-off units (14), the housing (32) of which has two branch chambers (41, 42), which lie transversely to the direction of flow, with pipe connection pieces (42 to 46) arranged on the outside on both sides. These branching-off units can also form, with heat-exchanger elements (27, 29, 31), independent built-in units. Their housing is passed through by three tube sleeves (51-53) which are connected into the individual lines and have in each branch chamber a lateral opening (56) which can be completely or partially closed by a throttle element (61). In this manner, it is possible at each branching-off point to divert a possibly preset part of the heat transfer medium out of the forward-run line (24) via the branch chambers (41), the heating element (27, 29, 31) and the branch chamber (42) into the added return-run line (69) or directly into the return-run line (25). As the added return-run line (69) is closed at both ends although its branching-off opening (59) is constantly open to the branch chamber (42), the heat transfer medium flows out of its end likewise through the branching-off opening (55) into the return-run line (25). <IMAGE>

Patent DE-3217476-A1 (DE)
Title: Laryngoscope
IPC: A61M16/00
Filed: 1982-05-10
Abstract: The invention is based on a laryngoscope the tube of which has an essentially circular shape at its distal end in cross-section perpendicularly to its longitudinal axis and is provided with a handle part. By comparison with this, the invention is based on the object of making it possible to treat children and patients of different sizes with the same laryngoscope. In addition, it is intended to offer an optimum view of the larynx. For this purpose, the tube is made in two parts in its longitudinal direction with an upper and a lower spatula-shaped part which can be pivoted relative to each other about an upper swivelling axis. This permits not just observation but also operation, in that the accessibility of the oral cavity and the larynx from either side is much greater. Further features make it possible to dispense with a further adjustment possibility, for example by a spindle drive. The expanding movement can be made by an adjusting screw or manually counter to the force of a spring. The adjusting screw can be used to set and fix an accurate angle. <IMAGE>

Title: Method of X-ray tomography for representing a body section image
Inventor: KRUEGER WOLFGANG DIPL ING
IPC: H05G1/08
Filed: 1982-08-02
Abstract: In the method of X-ray tomography for representing a body section image, X-ray pulses generated by a radiation source penetrate the body to be examined in a predetermined manner and are converted into electrical signals by radiation detectors. The detector signals thus obtained are then evaluated by using electronic storage systems. To increase the signal/noise ratio of the detector signals without requiring a corresponding increase in the radiation dose rate, the invention provides for each X-ray pulse to be additionally amplitude- modulated or sampled. In particular, a modulation or sampling frequency within a range of between 5 kHz and 100 kHz can be selected.
Patent DE-3230487-A1 (DE)
Title: Method for measuring low mass flows using a thermal principle
Inventor: PLATTES AXEL DIPL ING
IPC: G01F1/684
Filed: 1982-08-17
Abstract: The method is suitable for measuring the mass flow of gases and liquids in a range from 50 g/h to 500 g/h. It operates basically in conformity with the known thermo-anemometric principle. By contrast with other similarly operating devices, here the temperature gradient is kept constant temporally and spatially along the tube wall under all flow conditions. This measure renders the measurement result independent of the thermal conductivity of the medium.

Title: Permanent traffic recording system
Inventor: BREHMER SIEGFRIED ALEXANDER
IPC: G07C5/08
Filed: 1982-11-26
Abstract: The patent applied for under the title <<Permanent traffic recording system>> consists of one or more lens units, a transmission link to a regenerative memory and a picture developing unit that is to be triggered by sensors. The traffic observation system records the traffic situation vehicle by vehicle while driving or - in the case of battery operation - in the state of rest. The pictures taken are transmitted on the transmission link (e.g. glass fibre lines) to a recording unit which can be reused virtually without limits and which operates physically in accordance with the electrostatic principle. The pictures recorded there are retained and erased after a short time in order to create <<room>> for a new picture of the surroundings. Should an accident occur, impact sensors come into action which prevent erasure of the pictures last recorded and cause a picture to be output in the form of a copy on paper. The accident is thereby irrevocably retained. The technology of the recording unit and of the development and outputting of the finished copy is already known and has proved itself through the medium of plain paper photocopiers. What is novel is the idea of combination with the remaining components and the possibilities thereby rendered possible as use as an observing instrument for any type of traffic. A general application would also be conceivable wherever the aim is to retain fleeting impressions without a permanent intermediate medium and to make them visible only when required, and ...
