Title: System for piling up remnants of same size and pattern - uses one operator to feed off cuts onto holder strip of conveyor
Inventor: MAUL RUDOLF
IPC: A41H43/02
Filed: 1980-12-24
Abstract: The machine produces stacks of remnants having the same size and pattern from off-cuts of different size and patterns which are obtained from a cutting machine and stacked on a table. The topmost remnant on the pile is seized along its cut edge by a holder strip which is then raised up and moved by a supply mechanism (14) into the hanging magazine (12). The sheet of material is then transferred from the magazine by a tip-up mechanism which causes the sheet of material to move down in the horizontal position onto a table containing remnants of the same pattern and size. The whole operation can be carried out by one person whose task is to raise the remnant up until it is seized by the holder strip.

Title: Electrical apparatus and machine connecting cable having particular mechanical resistance and flexibility
Inventor: HENTZSCHEL WOLFGANG DIPL ING
IPC: H01B7/02
Filed: 1981-02-13
Abstract: This cable which can preferably be used for operations in rugged mechanical operation and for flexible deflection with very small bending radii, as a result of the special cable construction and the specific material selection. In the event of compression, torsion and bending stresses, the wire assembly which is critical to the function is protected by a cushioning effect. At the same time, the wires in the compressible intermediate layer can deflect mechanical stresses in a limited manner at right angles to the cable axis without this leading directly to wire fractures as in the case of rigid outer sheaths. The cable construction is illustrated in Fig. 1 and shows that all the winding spaces (1) of the stranded composite element (2) (formed by the wires) and the intermediate layer (3) are filled with soft, preferably foamed plastic material, and the outer contour of this layer is sheathed with a wear-resistant jacket (4). <IMAGE>
Patent DE-3106530-A1 (DE)
Title: Device for determining instantaneous flow rates
Inventor: BAIER PAUL W PROF DR
IPC: G01P5/18
Filed: 1981-02-21
Abstract: The invention relates to a device for determining the instantaneous flow rate in flowing media, in which slight differences, dependent on place and time, in the state of mutually delimited subvolumes are generated by a transmitter in the flowing medium and are detected by at least one sensor arranged downstream of the transmitter in the flow direction. The propagation time of the changes in state between the transmitter and sensors is a measure of the flow rate. As a consequence of correlative evaluation of the transmitter and sensor signals, the device is distinguished by an exceptionally slight influence on the state of flow of the flowing media. Consequently, it is suitable both for measurements in homogeneous, laminar-flow flowing media, and in turbulently flowing single-phase or multiphase flowing media. Since the sensors detect imported differences in state, the device can be used independently of the temperature of the flowing medium. Figure 1 shows an exemplary embodiment of the invention. A transmitter (3) and a sensor are inserted in the measuring tube (1) through which the flowing medium (2) flows. The blocks (5, 6 and 7) serve to generate signals and convert sensor signals; the blocks (8, 11 and 14) form the correlator. The blocks (17, 20, 21 and 22) are used to evaluate correlator signals and to display flow rates. <IMAGE>

Patent DE-3109012-A1 (DE)
Title: Device for actuating the main switch of an electrical power unit
Inventor: KUEHN WALTER
IPC: B60L9/00
Filed: 1981-03-10
Abstract: When switching on and off the main switch for electrical power units which are fed from an alternating current contact line, transient recovery processes and transient decay processes may occur due to the inductivity of the transformer in conjunction with the impedance of the contact line, during which processes voltages of relatively high frequency occur which may bring about unacceptable influences on signalling and telecommunications systems. These interference frequencies can be avoided in accordance with the invention in that a control device for the drive element of the remotely controllable main switch is provided by means of which the opening and the closing of the switching contacts is made possible at a selectable time of the voltage or current curve of the current flowing across the switch or of the voltage applied thereto.

Title: Method of eliminating leaks in the soldering joint of a television picture tube
Inventor: KREBS KARL-HEINZ GUENTHER
IPC: H01J9/50
Filed: 1981-04-29
Abstract: For eliminating leaks in the soldering joint between the screen part (2) and the funnel-shaped glass part (3) of a television picture tube (1), it is proposed to remove the soldering joint (5) to part of its depth from the outside at the leaking point, thereby widening the gap (4) between the two glass parts (2 and 3), to fill the cavity (7) produced by the removal with glass solder (8) and to make the latter flow and crystallise out by heating to soldering temperature. This makes it possible by way of system renewal to regenerate even picture tubes in which capillary channels passing through the soldering joint have formed during operation and through which air was able to penetrate into the interior of the evacuated picture tube and destroy the vacuum. Until now, it was not possible to renew such picture tubes. <IMAGE>
Patent DE-3117029-A1 (DE)
Title: Cable bushing with strain relief
Inventor: SIMON HANS
IPC: H02G3/06
Filed: 1981-04-29
Abstract: The invention relates to a cable bushing with strain relief. Such a cable bushing consists essentially of a bushing sleeve which is firmly inserted into a housing aperture, and a clamping element which is inserted into the sleeve and grips the cable. Electrical connecting cables are inserted through the housing wall, by means of the cable bushing, into the interior of electrical apparatuses or machines. If external tension is applied to the cable, the tensile force is transmitted via the sleeve to the housing, and the electrical conductors, and thus the connecting terminals inside the housing, are in consequence relieved of the tensile force and can thus not, for example, accidentally be pulled loose. The actual clamping or tensioning device of the clamping element is formed by two mutually opposite clamping strips which rest on the cable over a part of the circumference in each case. One end of the clamping strips is in each case fixed with respect to the sleeve. The other end in each case is seated on a head part of the clamping element which can be rotated with respect to the sleeve and can be latched in the respective rotation position. Twisting the head part with respect to the sleeve in one direction produces clamping, and twisting in the other direction releases the cable.

Title: Method for producing measurement resistors for a resistance thermometer, and a device for carrying out the method
Inventor: BREM WALTER DR ING
IPC: H01C17/232
Filed: 1981-05-06
Abstract: A method for producing electrical film resistors as measurement resistors (14) for a resistance thermometer, in the case of which a thin film (2) consisting of a metal whose electrical resistance has a high temperature coefficient, especially a platinum thin film (2), is applied in a firmly adhering manner, by cathode sputtering, on a main surface of an electrically insulating, flat carrier body (substrate) (1). Said thin film (2) is structured (patterned) in a meandering shape and small tolerances of the resistance value are compensated for. In this case, the structuring and the calibration of the resistance value of the platinum thin film (2) are carried out using a laser beam (3) which is controlled by a multiple substrate (1) for a multiplicity of measurement resistors (14) being placed on a heat-insulating base (5) by means of which, during the structuring and the fine calibration (which is carried out immediately thereafter) of a measurement resistor (14) the temperature of the measurement resistor (14) to be calibrated is measured, and the resistance value at normal temperature is calculated from the measured resistance value at this temperature, and the calibration process is terminated when the desired nominal value of the normal resistance value of the measurement resistor (4) is reached, within very tight tolerances. <IMAGE>

Patent DE-3137519-A1 (DE)
Title: Fuel injection system
Inventor: WISSMANN MICHAEL DIPL ING
IPC: F02M69/54
Filed: 1981-09-22
Abstract: A fuel injection system is proposed, which serves for the feeding of fuel to a mixture-compressing spark ignition internal combustion engine. The fuel injection system comprises a fuel pump (5), which by way of a non-return valve (7), opening in the direction of flow, delivers fuel into a fuel feed line (3) with at least one fuel metering valve (1). Line (25) leads to a pressure control valve (26), by means of which a constant fuel pressure is maintained in the fuel feed line (3). Upstream of the pressure control valve (26) a fuel reservoir (46) with rigid walls, which is filled with fuel and constantly flushed through, is arranged in the line (25). The fuel reservoir (46) is arranged on the cylinder head (45) of the internal combustion engine with as good a thermal contact as possible, at a point where, when the internal combustion engine is switched off, a higher temperature prevails than at other points of the internal combustion engine with which other components of the fuel injection system come in contact. As a result, when the internal combustion engine is switched off and the fuel pump (5) is not delivering fuel, vaporisation of fuel occurs in the fuel reservoir (46) only so long as the fuel present in the fuel reservoir (46) is sufficient to make up for fuel leaking out. In this way immediate starting of the internal combustion engine is ensured. <IMAGE>
