Title: Three-dimensional (3-D) television without any additional viewing aids
Inventor: KLATT PETER
IPC: H04N13/00
Filed: 1987-07-24
Abstract: In the case of this method, a rectangular-waveform voltage (5) which is supplied from a variable frequency generator is passed to the 74LS74 IC (1) via a 7805 voltage regulator (4). This IC (1) converts one rectangular-waveform voltage (5) into two rectangular-waveform voltages (6 and 7) which pulsate in antiphase. One of these rectangular-waveform voltages is in each case supplied to in each case one of the two 4066BE ICs (2 and 3 respectively). If the level is high (+5V), these ICs switch through the two connections (A1 and A2) and (A3 and A4) respectively. The video signal from a video camera (8) is in each case connected to the connections (A1 and A3 respectively). The connections (A2 and A4 respectively) are connected via a synchronisation adaptor (9) and a video amplifier (10) to the monitor or to the television, so that the images from the two video cameras (8) appear alternately on the monitor or television screen (11), as a function of the rectangular-waveform frequency. Starting with a low clock frequency, said frequency is now increased until the two images, which differ from one another slightly in terms of perspective, as perceived via the eyes, are merged by the human brain into a single three-dimensional image. <IMAGE>

Patent DE-3800718-A1 (DE)
Inventor: BUSCHFELD HANS PROF
IPC: A47G1/16
Filed: 1988-01-13
Abstract: Pictures or other objects hung on a wall could be illuminated hitherto by means of compact lamps in an unsatisfactory manner in terms of design. In order to achieve an improvement both in respect of the construction and the design, the picture rail is constructed as a profile rail (6) which serves at the same time as an electric conductor and is connected to a current supply. The hanging elements (7) are likewise constructed as electric conductors and are in connection via contact heads with the respective electric phase of the profile rail (6). A lamp (11) can then be attached to the hanging elements (7), the support parts of which lamp form the electric conductors at the same time. This enables a filigree-type design if thin or possibly springy wires are used. <IMAGE>

Title: Mixture of material for producing a metal chalcogenide and use of such a mixture
Inventor: CHATZITHEODOROU GEORGIOS DR
IPC: C30B23/00
Filed: 1988-01-22
Abstract: Simple measures which can essentially be carried out according to a uniform concept are to make possible the production of metal chalcogenides of different types for different purposes. The materials to be converted are prepared in the form of a mixture which contains as components A) carbonyl(s) of a metal and B) a chalcogen-containing compound in a stoichiometric mixing ratio and C) an inert organic solvent, with the boiling point of the solvent determining the conversion reaction. Pyrite (FeS2), molybdenum sulphide (MoS2), tungsten sulphide (WS2), ruthenium sulphide (RuS2) and molybdenum ruthenium sulphide or selenide (MoxRuySz or MoxRuySez), precipitated as powder, can be pressed into blocks and used as source material for crystal growing, sometimes also as corrosion protection agent or lubricant or for coating rigid and flexible substrates.
Patent DE-3803779-A1 (DE)
Title: Radar antenna
Inventor: LIEM TIANG-GWAN DIPL ING
IPC: H01Q25/02
Filed: 1988-02-09
Abstract: In the case of a phase-controlled antenna array (phased array) having individual radiating elements (which are arranged in rows lying one above the other), one column pitch and in each case one row pitch per row of radiating elements, the rows of radiating elements are in each case split into two half-rows, each at half the row pitch. The transmitted power element which is provided for one row of radiating elements and is fed via the column pitch is split in a 3dB-90@-coupler into two identical parts for the two half-rows. During transmission, the 90@ phase lag caused in one branch by the coupler is compensated for by differently set phase lags in a double phase-shifting arrangement which is inserted between the coupler and the half-row pitches. During reception, the difference between the phase lags in the double-phase shifter is changed through 180@ with respect to that during transmission. The signal which is emitted at the second input of a coupler during reception corresponds to reception via the azimuth monopulse overall polar diagram of the row of radiating elements and is combined with the signals from the corresponding coupler outputs of the other rows of radiating elements in a reception column network, which is independent of the column pitch, for example in the manner of elevation monopulse evaluation, and is fed to one or more receivers. The received signals at the first inputs of the coupler correspond to reception via the azimuth monopulse difference polar diagrams of the rows of radiating elements and are [lacuna] in the column pitch to ...

Patent DE-3814226-A1 (DE)
Title: Earthquake protection (damping measure)
Inventor: BRUSNOWITZ GEORG DIPL ING
IPC: E02D27/34
Filed: 1988-04-27
Abstract: The present earthquake protection is intended to largely keep the horizontally running primary waves (compression - longitudinal waves) and the Love and Rayleigh waves away from the building by the stiffened base trough, and is intended to deflect the horizontal thrust via the trough around the building and transmit it in the running direction. The subsequently vertically running secondary waves (transversal or shear waves) are insulated in their vertical energy by "prepared sand" - almost identical grain size with admixtures of insulating materials - in the containers under the foundation supports. The sand lodged in the supports will immediately compensate for the occurrence of small differences in height during the quake. The earthquake protection (damping measure) is intended to reduce the intensity of quakes and thus render them less harmful. <IMAGE>

Title: Electric-pulse-carrying, wind-stable delimiting band for fencing animals in or out
Inventor: HOECK WOLFGANG DIPL ING
IPC: A01K3/00
Filed: 1988-07-04
Abstract: Electric-pulse-carrying, wind-stable delimiting band with contact bridges for fencing animals in or out. To simplify fencing systems, in particular for fencing in horses and other domesticated animals or fencing out wild animals, use is made of the fencing band which is made of highly flexible weather-resistant artificial fibres and, because of its construction, can be fastened to virtually all electric insulators. The good optical detectability is influenced very little by the chessboard-like openings for achieving a neutral wind action (no flapping or tipping), and the pulse wires, which run in the edge region and are connected by contact bridges against disruptions as a result of interruption of a pulse conductor, guarantee as great a contact possibility as possible.

Title: Butt-welding process for plates
Inventor: BUEDENBENDER BERND
IPC: B23K26/26
Filed: 1989-03-23
Abstract: For the butt welding of plate edges trimmed by simple shears, the plate edges are trimmed and fitted together in such a way that the burr formed in each case points in the same directions. After the abutting edges are firmly pressed together, the upright burr is pressed back by means of a tool so that it is able to fill remaining gaps at least in certain areas and the welding laser beam finds a sufficiently tight abutting seam, which ensures a weld which can be highly loaded mechanically and also proves to be leakproof.
