Title: Electrophotographic copying method
Inventor: NISHIKAWA MASAJI
IPC: G03G15/045
Filed: 1981-11-12
Abstract: An electrophotographic copying method for optionally producing a direct (positive) copy or an inverse (negative) copy of an original uses an electrophotographic recording material which has one above another on a conductive layer a first and a second photoconductive layer which are sensitive to radiation of a first and a second optical waveband, respectively. It can optionally be subjected to the following method steps before development, transmission and fixing:   a) simultaneous charging and irradiation of the recording material with an image of an original which is generated by radiation in the first optical waveband, followed by uniform exposure by radiation in the second optical waveband, as a result of which the charge retained in the dark zone of the charge image produces a positive charge image, or b) simultaneous charging and irradiation of the recording material with an image of an original which is generated by radiation in the first optical waveband, followed by an inverse charging operation which reduces the surface potential essentially to a zero potential and is followed by uniform exposure in the second optical waveband, as a result of which the charge retained in the bright zone of the charge image produces a negative charge image.

Abstract: In a cable-type window lifter (10), especially for motor vehicles, having a driver (20) guided along a guide rail (14) and engaging on a window pane, and having a pull cable (22) which is fastened to the driver (20) and which is guided along a cable loop from a first run-off point (A) on the driver (20), by way of a first cable deflection in the region of one of the ends of the guide rail (14), to a cable drive (12) and from this, by way of a second cable deflection in the region of the other end of the guide rail (14), to a second run-off point (B) on the driver (20), it is proposed, in order to increase the window-lifter stroke, that, when the driver is located between the cable deflections, the first run-off point (A) is nearer the second cable deflection than the second run-off point (B), and that the two run-off points (A and B) and/or the two cable deflections are so offset relative to one another in a direction at right angles to the longitudinal direction of the rail that, in all the positions of the driver (20), the cable portions (50 and 52) are spaced from one another and from the cable deflection assigned to the respective other cable portion. <IMAGE>
Patent DE-3200911-A1 (DE)
Title: Reusable borehole plug
Inventor: DRESPA GERD
IPC: E21B33/134
Filed: 1982-01-14
Abstract: In rock stabilisation in underground mining and tunnelling as well as in other applications, the boreholes are sealed off by means of a borehole plug which is restrained in the borehole. The plug is restrained by virtue of the fact that a sealing ring, arranged between a clamping disc and a check disc, is compressed and pressed against the borehole wall. The check disc, which is prevented from turning, for example, by barbs or a corresponding handle projecting from the borehole, has a projecting spindle on which a wing screw is rotatably arranged in such a way as to drive the clamping disc. This ensures uniform pressing of the sealing ring. After the pressing operation is complete, the borehole plug can be extracted again by correspondingly turning back the wing screw and releasing the borehole plug and can subsequently be re-inserted in other boreholes.   <IMAGE>
Patent DE-3201309-A1 (DE)
Title: Central, continuous adjusting mechanism, which is free of moments and forces, for positioning the seat height, the seat distance and the backrest for commercial furniture and car seats
Inventor: LORTZ WOLFGANG PROF DR ING
IPC: B60N2/225
Filed: 1982-01-18
Abstract: The invention consists of a universally usable adjusting mechanism which allows sensitive, continuous, central adjustment of two components, can be integrated, and guarantees a high degree of safety against jerky loading, whilst maintaining freedom from backlash, and convenient handling. This is achieved by a gearing arrangement, in which a plurality of gearwheels engage in both component tabs having a different number of teeth. By rotating the gearwheels, the two halves of the component tabs are displaced relative to one another. It can be achieved, by matching the numbers of teeth and by varying the modules and the angle of engagement, that the operating angle of engagement is the same on both component tab halves. Consequently, when the fitting tab is loaded backwards, blocking no longer takes place via self-locking, but the forces are absorbed without torque on the engaged tooth. As a result, said tooth acts as a "feather key". By favourable positioning of the gearwheels relative to one another, a statically defined system can be achieved so that, finally, the system forces also eliminate one another. These regularities can be implemented on an internal and on an external toothing. <IMAGE>

Title: Process for producing a compression-resistant reinforcement on the surface of pipes sheathed in plastic
Inventor: LANDGRAF HELMUT DIPL PHYS
IPC: B29C63/00
Filed: 1982-02-19
Abstract: The invention relates to a process for producing a compression-resistant reinforcement on the surface of steel pipes sheathed in thermoplastic, in particular polyethylene, the plastic being wound helically in the form of an extruded film strip around the surface, covered with an adhesive, of the steel pipes heated to a temperature between about 150 and 200 DEG C and set in rotation, whereupon the steel pipes are cooled immediately afterwards in a cooling zone. In order to make the thermoplastic sheathing resistant to mechanical influences in a cost-effective way, it is proposed that, after leaving the cooling zone, the plastic sheath is wrapped in a porous or wide-meshed bandaging strip, which is impregnated or coated with a plastic cement-containing mortar, the plastic sheath being brought to a temperature which is adapted to the composition of the cement mortar and accelerates the hardening of the latter, for example to 80 DEG C, by controlling the cooling in the cooling zone. <IMAGE>

Title: Device for protecting water-carrying channels, in particular pipelines, against pressure waves
Inventor: HERRMANN REINHARD DIPL ING
IPC: F16L55/045
Filed: 1982-03-15
Abstract: In a device for protecting water-carrying channels against pressure waves, in particular the pipelines (1) of cooling-water supplies in power stations, the pipelines are lined with cushioning at least over sections of their length - while leaving free the requisite cross-section of flow (Qi) of the pipe. This cushioning consists of annular layers (4) of cushioning material, joined in sequence in the axial direction of the pipe and bearing against the inner wall (1i) of the pipe, and a supporting cage (2, 3) for the layers (4) of cushioning material. The supporting cage is composed of annular discs (2.1), which are arranged flatwise between the layers (4) and bear with their outer periphery (2a) against the inner wall (1i) of the pipe, and with holding means (3), in particular axial supporting struts, connected to the inner peripheral zones of the annular discs and intended for the flexible mounting of the layers (4) of cushioning material in the radial direction and for at least keeping the annular discs (2.1) at a distance from one another in a flexible manner. The layers of cushioning material are formed in particular by a tube bearing in spiral windings against the inner periphery of the pipeline (1) and filled with cushioning material (6), and the annular discs are formed by a supporting spiral (2) for the tube (4), which, with its coils (2.1) wound flatwise, is arranged between the tube windings (4.1) and is supported on the inner periphery (1i) of the pipe. <IMAGE>
Patent DE-3219405-A1 (DE)
Title: Production method for an instrument material holder
Inventor: BULLINGER HENRY W
IPC: G01D11/02
Filed: 1982-05-24
Abstract: A material holder is produced by pressing a number of discs into an open cylindrical housing and welding them in. The shrinkage of the cylinder after the welding-in of the first disc is absorbed by selecting a smaller disc for the second press fit. A carrier column is welded to the last disc and the shrinkage of this disc due to the welding-on of the carrier column is absorbed by selecting a disc with excess dimension for attachment to the carrier column. The shrinkage of the last disc also creates a compensation for the additional shrinkage of the cylinder due to the welding-in of the second disc.

Title: Printing control device for a dot matrix printer
Inventor: MANIWA YOSHIO
IPC: G06K15/10
Filed: 1982-12-31
Abstract: A printing control device for a serial dot matrix printer is created which can continuously supply dot matrix data to a print head which must move at a predetermined speed, in which arrangement printing data can be received from outside without an interruption. Character patterns of various dot matrix sizes are in each case only stored in a required area of a character pattern memory. Character patterns are sequentially read out of the character pattern memory when the end of a character output is ensured. The size of character patterns can only be changed by changing the character pattern memory. (Diacritical) characters are even printed out in proportional spacing characters or large and small letters in conjunction with the desired characters without the speed of printing becoming slower or the capacity of a character pattern memory having to be increased.
