Patent DE-2846230-A1 (DE)
Title: Forming canal-shaped passages in a solidifying medium - by immersing pressure-distended flexible tubes in molten medium, solidifying it and releasing pressure to shrink tubes
Inventor: MEHLHORN FRANK
IPC: F28D20/02
Filed: 1978-10-24
Abstract: Canal shaped passages in a solidifying medium are formed by immersing flexible tubes in the medium while it is molten. The tubes are subjected to pressure to distend them. When the medium has solidified, the pressure is released and the tube shrinks to its original size. This then creates a hollow passage through the solidified material. The passage can then be used to circulate a heat transfer medium. Used esp. for use with latent heat stores. Allows either liq. or gaseous heat transfer media to be pumped through the solid block.

Title: Corona discharge electrodes - for foil surface treatment are hinged to square ozone extraction tube
IPC: H01T19/04
Filed: 1979-05-08
Abstract: In a corona discharge treatment for the surface of plastic and paper foils to increase their surface adhesive capacity the corona electrodes are arranged at a distance of 2 mm from the surface of the drum over which the foil moves. Each electrode is hinged independently at the top edge of a square tube and can be deflected downward by any irregular foil thickness. The square tube side under the electrodes has openings through which the ozone produced is extracted. The electrodes can be swung down to cover these openings when not in use. The subdivision of the electrodes reduces the cost of the design. The exhaust openings remove the ozone which may have an injurious effect on the operator.

Title: Contactless vibration measurement at inaccessible surface points - using optical fibre to transmit and return later light modified by Doppler effect
Inventor: WINTERHOFF HORST DIPL PHYS
IPC: G01H9/00
Filed: 1979-11-09
Abstract: An arrangement for contactless vibration measurement using the laser Doppler effect enables measurements to be made on objects at positions inaccessible to linearly propagated laser beams. The laser beam (2) is focussed on the centre of the end surface (4) of the fibre core of an optical fibre (5). The focus point is transported to the other end (6) of the fibre. The laser light is then focussed on the test object (9). The reflected light returns to the fibre via the object focussing lens (7) and is returned by the fibre to the measurement system (1). The optical fibre is a monomode fibre. The laser light is focussed on the input end (4) of the fibre such that all the light incident on the end face makes no more than a small angle with the fibre axis.

Title: Attachment of washing to a line - by gripping between sliding sleeves with frictional grip threaded on line
Inventor: BALIN CHAIM
IPC: D06F53/02
Filed: 1979-12-14
Abstract: Fixings for attaching washing to a line comprises sleeves of wood, plastic or other material having through the middle a hole of a diameter similar to that of the line, whereby they can be slid easily along the line, but hold the position in which they are put. Several sleeves are threaded onto the line, and articles can be attached by sliding together two of the sleeves to grip the article between the end faces. Advantageously, two taut lines side-by-side may be used, the sleeves having two parallel bores, one for each line. A single sleeve then suffices to fix an article, by gripping it between the two lines. The sleeves are cheap, simple and easy to use. They are unbreakable, impossible to lose, and are immediately to hand when required.

Title: Noise sensor for IC engine knocking - has small diameter piezoelectric compound membrane with reactive inertial mass to detect pre-ignition
Inventor: STOEPHASIUS RAINER DIPL ING
IPC: H04R17/02
Filed: 1980-04-12
Abstract: To obtain a piezo-electric body noise detector small enough for screwing to a car engine, and which should have its maximum sensitivity in the region of 8 KHz to detect engine knocking, a compound membrane is provided consisting of a piezo-electrically passive laminate and a piezo-electrically active laminate bonded together. The compound disc is clamped at the periphery or at the circular node region to obtain well developed bending forces and resulting output signals. To increase the latter, an inertial body is attached to the membrane either at the centre in the form of a small metal cylinder, or at the outer rim in the from of a ring like body (8). The output from the detector which ranges from 0.5 to 0.8 volts is used as an input to an electronic ignition control circuit which, on detection of knock noises, changes the ignition phase so as to eliminate premature explosions in the engine.

Title: Theft alarm for fitting to motor vehicle windows - uses continuous wire loop on inside of all windows connected to alarm unit
Inventor: GROSSMANN HERFRIED ING GRAD
IPC: B60R25/10
Filed: 1980-07-26
Abstract: The proposed circuit increases the vehicle protection provided by a normal alarm which is associated with unauthorised opening of doors and starting of the engine. By extending the supervision to the vehicle windows thefts from inside the vehicle by breaking the glass also set off the alarm. A wire conductor (2a-2e) is placed across each window on the inside of the vehicle. All these conductors are connected in series to form a loop which is then connected (3,4) to the alarm operating unit. Breaking a window results in breaking the wire thus opening the loop and initiating the alarm. For large windows two spaced wires may be employed. The wires can be fitted with plug connectors to join with fittings inside the vehicle. This enables the wires to be removed when the vehicle is in use.
