Title: Switching mechanism for protection devices
Inventor: KROLL DIETRICH DIPL ING
IPC: H02H5/08
Filed: 1982-12-28
Abstract: The invention relates to a switching mechanism for protection devices of liquid-cooled transformers, transformer stepping switches and inductor coils which are equipped with an expansion vessel. This switching mechanism consists essentially of a non-ferromagnetic guide rod (7) which is arranged vertically in a housing (1) and accommodates one or more magnetic switching contacts (6). The aim of the invention is to create a switching mechanism for protection devices, by means of which the field of application of the protection devices is expanded. According to the invention, a flap valve (19) is connected to one or more permanent magnets (21) which can be displaced between two ferromagnetic adhesion plates (22, 23). The adhesion plates (22 and 23) limit the original position and the activated position of the permanent magnet (21). The flap valve (19) is connected to the guide rod (7) such that it cannot rotate. The guide rod (7) is arranged in the housing (1) such that it can rotate. The flap valve (19) is constructed as an angled lever (bent lever), and the permanent magnet (21) as a ring magnet. <IMAGE>

Abstract: A method of printing and checking a printing image, e.g., bar codes, of a thermoprinter. The just-printed printing image is scanned after printout of a portion of the printing image on the paper web by means of an opto-electronic sensor which can move relative to the paper web, reading the just-printed printing image in the process. The read result is compared and checked with the originally entered data and, if an error is detected, the remainder of the printing image still to be printed or the just-printed printing image is marked by the printer as unusable, e.g., blackened.
Patent DE-3308388-A1 (DE)
Title: Wind power station
Inventor: ABRAHAM HANS-PETER
IPC: F03D3/00
Filed: 1983-03-09
Abstract: In accordance with the energy required and the available medium of the wind, this wind power installation can be designed in different sizes and in mass-produced towers. Advantage over conventional installations, e.g. Growian...: the installation need not be turned towards the wind. Again, the rotating towers have a more pleasing appearance than the wind vanes on high steel towers multiply guyed with cables. The safety factor is also substantially more favourable with a rotating unit lacking projecting parts by contrast with the wind vane principle. The installation described here can be installed virtually everywhere, e.g. even on a hill. It may further be mentioned that this way of obtaining energy is the most environmentally friendly and interferes even less in ecological terms than does a hydro-electric power plant.

If the height of the pile (1) of paper differs from a reference value, the insertion height of the dividing knife (6) into the pile (1) of paper is corrected via an evaluating and control arrangement (67) in accordance with the height difference of the pile of paper and the number of layers of paper to be formed. <IMAGE>
Patent DE-3311236-A1 (DE)
Title: Sheet-feed device
Inventor: KONISHI HIROSHI
IPC: B41J13/00
Filed: 1983-03-28
Abstract: In some printing machines, different formats of paper sheets, for example the A4, B4, B5 formats etc., have to be processed, and these must be fed to the sheet feed. Conventionally, the sheet-feed device is equipped with a shaft guide which extends in a direction almost at right angles to the sheet advance direction according to the width of the sheet used. According to the invention, there is a sheet-feed device, in which separate feed and pressure rollers are fastened to sheet guides of the entry shaft, one end of the guide engaging into a groove of a pressure sleeve in such a way that the pressure sleeve can run off at the end and be lifted out. Between the pressure sleeve and the sheet guide there is a spring which prestresses the pressure sleeve against the pressure-roller side, with the result that at least the pressure rollers, a separating hook, the pressure sleeve and a spring provided at the end of the print line can move along the sheet guide according to the sheet width. Consequently, the pressure rollers can assume the correct position if only one is moved manually along the sheet guide according to the sheet width. At the same time, the sheet can be pressed by the prestressing force which loads the right and left end in the same way, to make the insertion of the sheet easier. Moreover, the initial pressure point on the line is not changed, so that a printing check can easily be carried out.

Patent DE-3321274-A1 (DE)
Title: Electromagnetic pulse counter
Inventor: PETZ GEORG DIPL ING
IPC: G06M1/10
Filed: 1983-06-13
Abstract: Like other known counting mechanisms, the electromagnetic pulse counter consists of a stack of counters which is driven via a magnetic system. If an electromagnetic pulse is applied to the coil of the magnetic system, the hinged armature (item 10, Fig. 1) is attracted. This then starts the counting mechanism moving via the switching lever (item 6, Fig. 1) and the star wheel of the first counter (item 7, Fig. 1). Since different coils are needed for different operating voltages, the pulse counter is constructed in such a manner that the magnetic system (yoke and coil, items 8 and 9 in Fig. 1) forms one unit and can be exchanged without disassembling the pulse counter. The threaded bolt (item 11, Fig. 1) which can be optionally inserted is also constructed as a simple plug-in connection and can be easily inserted by hand. <IMAGE>

Patent DE-3337219-A1 (DE)
Title: Clamping device for clamping workpieces
Inventor: SCHOEN HANS
IPC: B25B5/06
Filed: 1983-10-13
Abstract: The clamping device serves to clamp workpieces to a machine table or a clamping plate of a cutting machine. It essentially consists of a beam-shaped clamp (1) which bears at one end on the workpiece, an adjustable supporting element (19) for supporting the clamp (1) at its other end, and a tie rod (6) which is frictionally held on the bearing surface. An adjusting screw (4) is provided on the tie rod (6) for adjusting the clamp (1) to the clamping height. The adjusting screw (4) is connected via a toothed-belt drive to a threaded rod (20) provided on the supporting element (19) in such a way that, with the adjustment of the clamp (1) to the clamping height at the workpiece, the supporting element (19) is at the same time changed in its supporting height and thus subsequent adjusting of the supporting element (19) is dispensed with. The force which brings about the clamping of the workpiece is not produced at the tie rod (6), as is common practice, but at the supporting element (19), and in fact either mechanically by turning a clamping nut (22) or hydraulically by means of a piston/cylinder arrangement (28, 29) which is accommodated in the supporting element (19). <IMAGE>

Title: High-tensile capping for an optical cable
Inventor: KORPORAL HANS-WERNER
IPC: G02B6/44
Filed: 1984-04-18
Abstract: The invention relates to a high-tensile capping, especially for an optical cable which has a central strain relief element and a sheath between which optical fibres are arranged, using a cable grip which is fitted to the cable end. In order to achieve the object of designing an arrangement of the type mentioned initially in such a manner that tension forces are also transmitted to the central strain relief element, it being intended to prevent damage to the optical fibres, it is proposed that the optical fibres be shortened axially with respect to the sheath and the central strain relief element, that a hollow-cylindrical tension anchor be arranged in the free annular gap thus formed between the sheath and the central strain relief element, the internal hole of which tension anchor has a diameter corresponding to the strain relief element, and whose annular body has radially penetrating slots over a majority of the axial length.

Title: Process and apparatus for separating mixtures by highly compressed gases
Inventor: MAIER MARTIN DIPL ING
IPC: B01D11/04
Filed: 1984-05-15
Abstract: The process and apparatus serve to separate mixtures by means of highly compressed gases, the carrier gas, in a known manner, as solvent being loaded with the substances to be extracted at high pressure, the extracted substances being subsequently separated off again by flashing and at the same time the carrier gas being continuously circulated. In the novel process and apparatus, the continuous circulation of the carrier gas proceeds by freezing and thawing of the gas, sequentially in sections, the flashing and subsequent compression of the carrier gas being achieved by a constriction and expansion of the piping cross-sections in the zone of the carrier gas which is freezing out. The conventionally used, expensive high pressure compressor and the pressure control can thus be dispensed with, since the described process proceeds only via supply and removal of heat.

Title: Process for the continuous embossing under heat and pressure of the surface of a thermoplastic film with a grain structure
Inventor: BOETTCHER HUGO
IPC: B29D99/00
Filed: 1984-02-20
Abstract: In a process for the continuous embossing under heat and pressure of the surface of a thermoplastic film with a grain structure, an embossing roller is used the surface of which has a negative form of the grain structure to be embossed and consists of silicone rubber at least in the region of its circumferential surface. During the embossing the thermoplastic film, or at least its surface, is heated to a temperature of at least approximately 150 DEG C, preferably 180 DEG -250 DEG C. By this intense heating, the thermoplastic film obtains at least in the region of its surface to be embossed a flowability so high that it penetrates into the extremely fine contours of the embossing roller, so that an exact transfer of the embossing structure onto the thermoplastic film takes place in a rapid continuous procedure.
