Title: Method for the transportation of energy at zero potential
Inventor: BAJORAT KLAUS
IPC: G01R15/26
Filed: 1981-01-17
Abstract: The invention relates to the transfer of energy to high-voltage potential in order to supply measuring and transmission devices at this potential. The transportation of energy should be at zero potential, maintenance-free, continuous and without complexity. The solution consists of an air or inert-gas link located in a closed insulating tube, which can also be the hollow high-voltage insulator itself carrying the measuring and information transmission device at high-voltage potential, being excited by an oscillation generator at earth potential at the frequency of an alternating-voltage generator in such a manner that a standing wave is generated inside the tube, that a permanently excited oscillation receiver is arranged at high-voltage potential at an antinode of the standing wave, which oscillation receiver couples out the energy of the longitudinal wave and generates an alternating voltage with which the measuring device and the information transmission device are fed, and that the natural frequency of the oscillation generator and the oscillation receiver corresponds to the resonant frequency of the air or gas column defined over the length of the tube. An illustrative embodiment is described with reference to the drawing. The invention is predominantly used in high-voltage direct-current transmission, in which the direct current and its polarity are to be measured at +/-500 kV potential with respect to earth. <IMAGE>

Title: Window lifter, especially for motor vehicles
IPC: E05F11/48
Filed: 1981-06-04
Abstract: In a window lifter (10) for motor vehicles, with a driver (16) engaging on a window pane, with a sliding piece (24) connected to the driver and mounted displaceably on a guide rail (26), and with a rope drive (12) for displacing the driver (16) along the guide rail (26), it is proposed to mount the driver (16) on the sliding piece (24) so as to be displaceable in the longitudinal direction (X) of the guide rail (26), specifically in a simple way in that the driver (16) is fastened to a bearing part which is itself mounted displaceably in the longitudinal direction (X) on the sliding piece (24). This ensures, by simple means, an increase in the stroke of the window lifter for a predetermined length (c) of the guide rail (26), whilst preserving the mechanical stability of the window lifter in respect of tilting movements of the window pane which lie in the plane of the window pane. A steel-band loop (44) is preferably used as a bearing part. In a further embodiment, the steel band is displaceably mounted directly in the guide rail designed as a C-rail, a deflection for the band being provided at at least one end of the guide rail. <IMAGE>

Title: Apparatus for isolating bottles delivered on a plurality of tracks
Inventor: KARASS HANS-JOACHIM
IPC: B65G47/68
Filed: 1981-07-18
Abstract: The invention relates to an apparatus for isolating bottles delivered on a plurality of tracks onto a single-line closed track consisting of a plurality of plate belts extending side by side, whose speed increases, preferably constantly, from plate belt to plate belt as far as the individual track. In this case, slight back-ups can arise in the transfer region which impede the smooth flow. According to the invention, a bottle sensor which is known per se is now arranged in the region of the transition from the last lead-up belts to the individual belt and, in the event of bridging of two or more bottles to be threaded in, can be actuated by the latter and produces a short-term stoppage of at least one plate belt located in this area. A smooth threading-in operation is ensured by this measure.

Title: Method and device for producing furniture or housing parts with curved corners
Inventor: RIEGER ERWIN
IPC: B27H1/00
Filed: 1981-08-06
Abstract: In the method of producing furniture or housing parts with curved corners from a pressboard panel surface-treated at least on one surface, in particular coated with a film or veneered, the pressboard panel, in the area of the subsequent corners on the inside of the bend, is provided with recesses extending along the respective bending axis. The recesses in each bending area are formed by a multiplicity of impressions which narrow from the inside of the bend to the outside of the bend, extend right into the proximity of the outside of the bend and are staggered relative to one another in such a way that the pressboard spots remaining between the impressions are connected to one another by webs. Then a glue is applied in the bending area to the inside of the bend. The glue penetrates into the impressions, the pressboard spots and the webs and softens the pressboard panel. After it is softened in the bending area, the pressboard panel is brought to bear with its surface-treated side against a flexible supporting belt, is secured relative to the supporting belt in the longitudinal direction of the latter, and then the two panel parts adjoining a bending area are bent towards one another into the desired end position around a counterstay, bearing against the inside of the bend, for forming the round corner. In a device for carrying out this method, a multiplicity of punches (11) narrowing towards their free end are staggered with respect to one another on a common pressure plate (18). <IMAGE>

Filed: 1981-08-06
Abstract: Each of the two switch drives (1, 2) has a screw spindle (13, 23) which can be rotated by motor and/or manually and on which a travelling nut (15, 25) runs which drives a switching shaft (151, 251) via a pivoting lever (150, 250). A link (19, 29) which can be moved by the travelling nut (15, 25) is allocated to each drive (1, 2) and is mechanically connected (30) to the other link (29, 19) such that the two links (19, 29) can move only together. Each link (19, 29) has three possible positions, namely an off position, an on position and a locked position. The two links (19, 29) are always located together in the off position. If one link (29) is moved by the travelling nut (25) from the off position into the on position, then it moves the other link (19), via the mechanical connection (30), from the off position into the locked position, in which it mechanically locks (16 and 140) the associated drive. <IMAGE>

Title: Method and device for generating short narrow-band sound pulses by means of ultrasonic probes
Inventor: DEUTSCH VOLKER DR ING
IPC: G01N29/22
Filed: 1981-10-23
Abstract: The main field of application is the non-destructive testing of materials, but the invention can also be used in other fields in which ultrasound is used as a means for a test method. The invention has the purpose of reducing the expenditure hitherto associated with generating short narrow-band sound pulses by means of wide-band resonators and, as a result, provide for high test sensitivity and the evaluation of the test finding by means of AVG diagrams. It is characterising for the invention that the capacity of a mechanically highly damped resonator is connected in parallel and/or in series with an inductance of such a magnitude that this results in a narrow-band sound pulse of predetermined centre frequency. The coils for the probe circuit, the overall circuit diagram of which is shown in Figure 3, are accommodated, together with an electronic device for measuring the actual centre frequency, in a housing which must be connected directly into the line between an arbitrary ultrasonic device and a mechanically highly damped resonator. <IMAGE>

Title: Wood cements
Inventor: GABERT KURT
IPC: C08L97/02
Filed: 1982-02-06
Abstract: The invention relates to wood cements for treating flaws and irregularities in constructional parts of wood, wood-like materials and other absorbent materials. The object of the invention is to improve the use properties of wood cements in such a way that they no longer contain any organic solvents (elimination of health-impairing effects and fire-protection measures), ensure reliable and rapid processing (unlimited pot life, high solids content, rapid drying) and have, in the cured state, a high adhesion strength towards the wood and high hardness. According to the invention, this object is achieved by using, in addition to inorganic fillers, wood flour and dyestuffs or pigments, aqueous polymer dispersions (solids content at least 50%) as binder, which contain dispersed polymers having a glass transition temperature from 293 to 313 K and, in addition, 2 to 4% of water-soluble polymers containing hydroxyl groups, preferably polyvinyl alcohols or cellulose derivatives. The dispersed polymers can, for example, be homopolymers of vinyl acetate, copolymers of vinyl acetate with acrylate esters or maleate esters (comonomer content: 5-15%) or copolymers of ethyl acrylate or butyl acrylate with styrene or methyl methacrylate (comonomer content: 40-50%).

Patent DE-3219677-A1 (DE)
Title: Device for the taping of material
Inventor: WINGERTER FRANZ
IPC: H01B13/08
Filed: 1982-05-22
Abstract: A device for the taping of cables or the like with material in the form of tape has a spinning plate (1) which rotates around the respective cable and supports guide rollers (8) for the material in the form of tape. Said material is supported in the form of a roll (6) on a sleeve (5) which can rotate with respect to the spinning plate, and is passed via the guide rollers to the material which is to be taped. The roll is caused to rotate by the tension which is exerted on the material in the form of tape by the rotating spinning plate. The tension in this material is produced by a disc brake (10) which is located between the spinning plate and the sleeve. In order that this tension remains constant even when the roll diameter is changing, the disc brake is automatically adjustable. This is done by determining the respective tension in the material in the form of tape via the deflection of one of the guide rollers, which is supported in a moving manner under spring tension. In the event of a deviation from the predetermined tension, a bush (12) which acts on the disc brake is displaced axially by a motor (20), in the sense of achieving the desired braking moment. <IMAGE>
