Patent DE-3009557-A1 (DE)
Title: Racing track for digitally controlled electric toy vehicles - has insulating segments marginally wider than vehicle contact wipers
Inventor: FLEISCHMANN OSKAR
IPC: A63H18/16
Filed: 1980-03-13
Abstract: All cars receive the same propulsion voltage with superimposed coded control pulses. Each vehicle receives and evaluates control signals addressed to it and uses them for speed changes, starting and stopping transitions, left-right turns or manouvres, and also for switching on and off lights and warning sirens. The race course is built up of a number of longitudinal contact rails (2,3) with insulator segments (1) between them. Rails are alternatively connected to the supply poles (6,7). The vehicle wipers (8,9) feed the motor (M) via a digitally controlled attenuator circuit. The distance between wiper brushes correspond to the distance between the contact rails and the insulating strip (1) between is only slightly wider than the width of the wiper brushes (8,9). The control logic is so arranged that, when the speed is reduced towards zero, the vehicle automatically turns to back up closest to a side barrier (4,5) so that the contingency of the vehicle stopping at an intermediate voltage free location is excluded.

Title: Photoreceptor prodn. with multi-chroitic colour strip filter - useful for coding and decoding using photoresist and vapour deposition of interference layers
Inventor: STEMME OTTO DIPL PHYS DR
IPC: G02B5/28
Filed: 1980-04-03
Abstract: In the prodn. of a photoreceptor with a multichroitic colour strip filter, the interlocked filter strip systems are applied in consecutive process stages, each involving coating the substrate with photoresist, exposing through a suitable mask, developing the photoresist, vapour deposition of the desired interference film for the filter colour concerned and then removing the remaining photoresist. The photoreceptor is useful for coding and decoding. Filters with very steep sided spectral transmission curves can be produced. Pref. the photoresist and overlaying superfluous filter film is lifted off by swelling with organic solvent, pref. dimethyl ketone. A positive resist with a thickness of min. 1 micron is used. Chemically and mechanically stable materials, e.g. highly refractive materials such as Ta205, TiO2, ZnS etc., or materials with low refraction such as MgF2, SiO2, ThO2 etc., are used to produce the filter layers. The substrate is a plane-parallel glass plate, which is aligned with the photoreceptor, or the photoreceptor itself. The filter strips can be longer than the width of the effective area of the photoreceptor.

Title: Generation of potential energy - by induction of quadrupole fields by excitation of two electron orbits
Inventor: HANSCHMANN HORST
IPC: F03H99/00
Filed: 1980-07-23
Abstract: In a system for the prodn. of potential energy, high-frequency currents are transformed to two phase-shifted rectified currents by which a material with two electron orbits is induced to generate quadrupole radiation fields. The latter can be used to change the weight in the gravitational field of the earth by 50-500 g, if electromagnets are attached to the spokes of a rotating device. The weight differential of the electromagnets grows with the square of the acceleration. This effect can be used to overcome the force of gravity or for the prodn. of long-chain plastics.

Title: Determining stationary leakage rate of solid bodies - deriving differential of diffusion signal by detecting first order max.
Inventor: HETTINGER WOLFGANG
IPC: G01M3/20
Filed: 1980-10-09
Abstract: The quantity of gas diffusing through the solid bodies is measured. The method is applicable to plastics tubes reinforced with glass fibres and enables the stationary leakage rate to be determined more rapidly than previously possible and some time before the rate has settled. The first or second differential of the measurement value is formed until the first differential reaches a maximum or the second differential reaches zero. At this point the corresp. leakage rate is a defined fraction of the stationary leakage rate. The arrangement contains a conventional leakage detector (2) and indicator (7) with an intermediate evaluation unit (6) consisting of a differentiator and comparator.

Patent DE-3044823-A1 (DE)
Title: Vehicle double towing hook - has body provided with spring loaded locking pegs to close hook openings
Inventor: FRIESE PAUL
IPC: B60D1/18
Filed: 1980-11-26
Abstract: The double towing hook consists of a hook body which can be forged or moulded with two opposing hooks in which are drillings for sliding pegs which are spring loaded. The drillings do not pass right through the hook body, so that dirt does not enter to hinder the movement of the peg. By pressing the towing chain or rope against the sloped end of the peg, the peg enters the hook when the spring returns the peg to lock the chain in a foolproof way so that it cannot open by itself.
Patent DE-3100033-A1 (DE)
Title: Sealing, bearing and control element system for rotary-piston internal combustion engines, pumps and compressors
Inventor: OTTO KARL
IPC: F01C21/08
Filed: 1981-01-02
Abstract: The narrow sides, let into the rotary piston (4), of the strips (3), adjustable using the fixing screws (5) and accurate to a few hundredths of a millimetre due to the exchangeability of the foils (6), pull the strips into the rotary pistons (4) and ensure the desired thickness of the sliding/sealing gaps at the large faces of the rotary pistons. The outer profile extensions not only prolong the high sealing quality particularly at the piston deflector edge but also take up a considerable part of the bending moments which act on the broad sides of the rotary pistons (4). Due to guidance in the cam groove (H) of the covers, the eccentrically adjustable pins (7) press the entire width of the piston deflector against the outer wall in accordance with the sealing requirement. The bridging trough (17) is a component which, with the control elements which it contains, not only controls the exhaust and intake processes, separately for the two sides (1-2) of the disc cam, but also makes the progress of these processes adjustable, this being achievable at a favourable cost by, for example, adjusting the worm pitch by replacing the small part with a small part of a different pitch. Following an explosion in the combustion chamber, this could require an intentional delay of about two degrees of revolution in the expansion in the working chamber for reasons of efficiency. <IMAGE>

Title: Hook switch for telephone sets
Inventor: GRASSL ERWIN
IPC: H04M1/08
Filed: 1981-03-24
Abstract: The movement into a switching position which corresponds to the electric quiescent condition of the telephone set when the handset is on-hook (Fig. 2) of a plurality of contact springs (6) disposed in a hook switch housing (1) and interacting in groups by means of a common drive slide (14) guided vertically in relation to the housing is intended to be achievable with an extremely small drive force. For this purpose, the contact springs which can be moved by the drive slide (14) are in part elastically pre-tensioned in opposite directions to one another. A dedicated reset spring (17) which, in its rest position, holds the drive slide in one of its two locking positions is provided with an essentially rectangular cross-section profile (18) stiffened with an arc-shaped curve. For mechanical actuation of the hook switch in this design by replacing a handset on the telephone, the stiffening effect of the profile curve of the reset spring must first be counteracted. The reset spring then resists further movement with only minimal, slightly increasing force. <IMAGE>
