Title: Typewriter or similar office machine with a cleaning device for machine parts coming into contact with ink ribbons
Inventor: STEINICKE GUENTER ING GRAD
IPC: B41J35/00
Filed: 1981-11-21
Abstract: The use of ink ribbon cartridges with correctable ink ribbons in typewriters or similar office machines leads to soiling of the machine parts coming into contact with these ink ribbons. Even the machine parts arranged below the receiving device for the ink ribbon cartridge can become soiled in such a way that malfunctions occur during the transport and the lifting of the ink ribbon. These soiling deposits are removed according to the invention in that a cartridge (1) with a cleaning tape (11) is inserted in the receiving device (3). This cartridge (1) has control means, by means of which a cleaning program controlled by software can automatically be initiated when the cartridge is inserted in the receiving device (3). The operator is therefore no longer required to have any special skill. <IMAGE>

Patent DE-3205701-A1 (DE)
Title: Clamping head of a hydraulic sheet stretcher of welded construction
Inventor: KUTZ HEINRICH
IPC: B21D25/04
Filed: 1982-02-17
Abstract: The invention discloses a welded connection, new in comparison with conventional constructions, between the cross-beam of the clamping head of a sheet stretcher and the plates accommodating the clamping-head jaw. In the conventional connection, the individual plates, which had in addition to be tapered at their foot, were welded by means of fillet welds in a chamber-like prepared recess in the horizontal flange plates of the clamping heads. Due to a high stress concentration factor  alpha k, this very involved connection using plates welded by hand created critical conditions for the strength of the connection of the plates to the cross-beam. This disadvantage has been avoided by a better and simpler connection of the plates to the flange plates of the cross-beam. For this purpose, filler pieces are arranged between the plates at the plate base and the plates (3), together with filler pieces, are joined to the flange plates of the cross-beam by means of a butt weld that can be carried out by machine. The roots of the gaps between the plates and the filler pieces are bored out after welding, the bore diameter being approximately equal to or larger than the thickness of the filler pieces.

Patent DE-3224250-A1 (DE)
Title: Transfer accumulator with a hydro-pneumatic accumulator
Inventor: CLUCAS DAVID JOHN
IPC: F16L55/054
Filed: 1982-06-28
Abstract: The transfer accumulator has a transfer barrier with a housing (1) and inlet and outlet openings (2 and 3) at its opposite ends which are intended for fitting into the pipeline of a food processing plant. An elastic rubber sleeve or collar (5) is arranged inside the housing (1), and fluid is located in the space between the housing (1) and the sleeve (5). An opening (7) leads from the housing (1) to a conventional accumulator (9). Every rise or drop in pressure in the pipeline causes the sleeve (5) to be extended or compressed, which in turn leads to fluid being forced into the accumulator (9) or to it flowing out of the same until equilibrium is again obtained. The smooth inner surface of the sleeve (5) greatly reduces the tendency of food particles to adhere to it. Other types of transfer barrier can be used depending on the application. <IMAGE>

Title: Device for pivoting the panel halves of table-tennis tables
Inventor: HAIDER EDUARD
IPC: A47B3/087
Filed: 1982-11-02
Abstract: The invention relates to a device for reversible pivoting of the panel halves (5) of table-tennis tables from the horizontal playing position into an approximately vertical rest or transport position, with levers arranged underneath the panel halves (5) and hinged to them. By this means, the two panel halves (5) are pivotally connected on their underside, close to their middle edges (4), to at least one articulated plate (2) with a central cutout (3). Mounted on the articulated plate (2) are pivoting levers (11a, 11b), running parallel to the panel halves (5), with folding-leg stays (10) connected rigidly to them, the said levers being connected to the legs (6, 9) hinge-mounted on the panel halves (5) to form articulated parallelograms (14, 15, 20, 26, 20, 26, 27, 28). Between the articulated parallelograms assigned to the two panel halves (5) there is provided an asymmetrical gear connection, which during pivoting of the one panel half causes the other panel half to keep ahead or trail behind and consequently prevents the closely adjacent middle edges (4) of the panel halves (5) colliding. <IMAGE>
Patent DE-3240981-A1 (DE)
Title: Rubber-metal mount
Inventor: MUELLER RUDOLF DIPL ING
IPC: B60G7/02
Filed: 1982-11-05
Abstract: A rubber-metal mount (4) is described, having an outer and an inner metal sleeve (9, 10) and a rubber element (11) arranged in between. The lateral surface of the inner metal sleeve (10) has surface sections (10a, b) which are offset with respect to one another in the circumferential direction and in each case rise towards one of the two end faces. These surface sections (10a, b) achieve the effect that the mount (4) shifts in a predetermined direction when a force acts in an approximately radial direction on the mount (4). On the mount, the radial forces occur oppositely and with different lines of action. In order to achieve a predetermined shifting of the mount (4) in these cases as well, the surface sections (10a, b) have different angles of rise. The mount is suitable for rear axle constructions of motor vehicles having separate transverse and longitudinal guidance. <IMAGE>

Title: Facade cladding and roof covering
Inventor: SCHNEIDER FRITZ
IPC: E04D3/30
Filed: 1983-03-08
Abstract: A plurality of sheet metal type panels (1) have a smaller groove (2) in the region of their one longitudinal edge and a larger groove (2) in the region of their other longitudinal edge. In this arrangement, the smaller groove (2) of one panel (1) is in each case clamped into the larger groove (2) of an adjacent panel (1). In this way, all panels (1) are non-positively interconnected. The openings of the grooves (2) clamped around one another come to bear towards the outside and a rod or a tube (3) is pushed into each of these double grooves. This improves the cohesion of the panels (1) and gives the cladding or the roof covering a nicer appearance. Each double groove (2) of the panels (1) is enclosed in clamping manner by a clamping rail (4). The clamping rails (4) are fixed by their rear sides directly, or indirectly via mountings (6), to the building wall (7) or to the roof structure. A heat-insulating air space is situated under the panels (1). <IMAGE>

Patent DE-3326602-A1 (DE)
Title: Device for compressed-air blasting
Inventor: FROHNE KLAUS
IPC: B05B7/14
Filed: 1983-07-23
Abstract: The invention relates to a device for forming and directing the working jet in compressed-air blasting with a conventional blast nozzle. The aim of the invention is the improved utilisation of the energy applied in compressed-air blasting. The object is to eliminate to the greatest possible extent the uncontrolled admission of ambient air to the working jet. A device is proposed in which the area following the orifice of the blast nozzle is surrounded by a concentrically arranged sleeve which is open in the blast direction and has an inside diameter at the blast-nozzle orifice at least as large as the blast-nozzle orifice, an orifice diameter filled by the working jet and a length corresponding approximately to the jet spacing. Air-inlet openings are arranged to compensate for the vacuum developing in the sleeve. Inlet-air cross-section and sleeve length are adjustable. Due to the working jet being directed in the sleeve, the energy exchange with the ambient air is prevented to the greatest possible extent, as a result of which more energy is available for stock-removal work. The invention can be used in all compressed-air blasting units with freely discharging jet. The device is shown in Figure 1. <IMAGE>

Title: Pot-shaped contact piece for electrical vacuum switching tubes
Inventor: BETTGE HANS ING GRAD
IPC: H01H33/664
Filed: 1983-07-29
Abstract: Pot-shaped contact pieces for electrical vacuum switching tubes normally have a contact base, a cylindrical wall with slots which run obliquely with respect to the rotation axis, and a contact ring. In order to prevent the arc jumping on to the pot base (1) during the switching-off process, and hence in order to achieve an increase in the short-circuit switching-off current, it is proposed to fill the internal space of the pot-shaped contact piece, formed by the cylindrical wall (2) and the pot base (1), with an insulating body (10), and to allow the contact ring (3) to project beyond the cylindrical wall (2) on its internal diameter. Contact pieces according to the invention can be used advantageously for very high switching-off currents in vacuum switching tubes. <IMAGE>
Patent DE-3329506-A1 (DE)
Title: Receiver in a system operating with band spreading (spread-spectrum)
Inventor: BAIER PAUL WALTER PROF DR ING
IPC: H04B1/707
Filed: 1983-08-16
Abstract: In a spread-spectrum system, in which two or more mutually orthogonal spread-spectrum signal shapes are used for transmission, for receiver synchronisation the output signals, rectified in envelope detectors, of filters (1) signal-adapted to these signal shapes are compared individually with thresholds and the output signals of the threshold circuits (12) are further processed in an OR gate (13), the output signal of which is used as synchronisation signal. The circuit according to the invention is easier to implement, in particular in the case of signals of great band width, than the known, technically equivalent circuit for determining the respective maximum value of the envelopes of the filter output signals and its switching-through to the threshold. The receiver according to the invention can be used in the case of interference-resistant spread-spectrum message handling systems, in particular in the case of those for handling messages which in each case comprise a fixed number of successive signal shapes with agreed timing pattern. <IMAGE>
