Inventor: FREI ALFRED
IPC: B23K11/14
Filed: 1983-12-28
Abstract: In an apparatus for joining two metal plates (22, 24) or layers (26) by pulse welding while deformations or bulges (23) provided in one metal plate are pressed into the other metal plate or layer (26), an electrode (14, 20) for carrying the energy required for the pulse welding is allocated to each metal plate or layer. The two electrodes (14, 20) are here arranged next to one another on a work surface (5) and are overlapped by a lowerable pressure plunger (10). One of the electrodes (14) rests in a channel (12) of a profiled piece (11) and is supported there against a stored-energy device. <IMAGE>

Title: Optical measuring system for monitoring the nominal values when pressing pipes without excavation
IPC: G01B11/27
Filed: 1984-04-04
Abstract: An optical measuring system for monitoring the nominal values when pressing pipes through the earth without excavation is described, in which two plane front-surface mirrors are used, one of which is semi-transparent and is arranged with respect to a triple prism arranged at the heading face in such a manner that the beam of a laser, which is directed from the outside against the other mirror, is reflected to the second mirror and hits the centre of the prism at the heading face, the mirrors being perpendicular above one another and one being arranged outside the pipe and the other one being arranged in the cross-sectional area of the pipe. The reflected beam of the triple prism then generates a measurement image on the semi-transparent mirror. If both images of the measurement image coincide, the nominal value is maintained.

Title: Method for transferring ceramic moulded articles on supporting laths and apparatus for implementing the method
Inventor: BRUGGER KARL
IPC: B65G49/08
Filed: 1984-07-07
Abstract: The invention relates to a method for transferring ceramic moulded articles on supporting laths, in which method the moulded articles are fed on a feeding belt or the like, in rows arranged transversely to the feeding direction, to a spreading device, by means of which the rows of moulded articles are pulled apart and then placed on supporting laths of a delivery station by means of a gripping device. It is the aim of the invention to develop the method in such a way that transfer from the spreading device to the delivery device can be carried out with simpler means. This is achieved in that the arrangement of the moulded articles (6) is pulled apart in the spreading device (9) to form groups (12) of two, three or more moulded articles (6), the distance (a) between the said groups being approximately equal to the product of the number (A) of the moulded articles (6) in the group times the desired size of the gap (c) and the groups (12) being pulled apart to that gap on the supporting laths (17) in the delivery station (16). The invention also relates to an apparatus for implementing the method, in which a pulling apart device (21) is assigned to the delivery station (16), the said pulling apart device (21) having pulling apart elements (29) which can be raised and lowered above and below the conveying plane (E), are horizontally displaceable and take hold of the undersides (13) of the moulded articles (6) in the regions left free by the supporting laths (17). <IMAGE>

IPC: H05H1/12
Filed: 1984-12-28
Abstract: In accordance with a method for producing electrical power for a nuclear fusion device with a polar coil load and a heating unit load, which are operated by a multiplicity of power source motor generators, the power loss is substantially reduced. All the power source motor generators are excited during periods of time in which a high current is required, including a plasma current excitation time and a plasma current stop time for the polar coil load, the plasma current excitation time being used for the heating unit load. During periods of time which include a plasma current maintenance time, in which the load is small, the power source motor generators are operated unexcited, while the electrical power is delivered to the loads from an additional power source of low capacity. <IMAGE>

Patent DE-3508525-A1 (DE)
Inventor: KURZ ARTHUR
IPC: G11B7/09
Filed: 1985-03-09
Abstract: The light beam is focussed with the aid of an optical system on to an optical recording medium. The optical system consists of a light source and a movable lens (20) which can be moved by means of servo-element (SG). The recording medium reflects the light beam on to a number of photoelectric cells (A, B, C and D). From their output voltages an initial control voltage is obtained by subtraction and addition of the differences thus obtained, and this is transferred by a servo-amplifier (RV) to the servo-element (SG) so that a closed loop system is formed. When the closed loop system is opened a second control voltage Us is fed to the servo-element (SG) and is modified. If the light beam is focussed on to the recording medium, the control loop system is again closed. The value of the second control voltage Us received at that moment is maintained and is available at the servo-element (SG) as a pre-voltage.

Title: Device for bringing together and joining the end of a web of packaging material
Inventor: WECKEND EBERHARD
IPC: B65H19/18
Filed: 1985-04-23
Abstract: Device for bringing together and joining the end of a web of packaging material to the start of a second web of packaging material on a wrapping machine, consisting of a packaging material table on which the corresponding supply rolls are mounted externally and opposite one another, from which supply rolls the webs are fed to a processing station through a gap in the centre of the packaging material table and, when a supply roll has been used up, are joined to one another, using a bonding agent, by means of pressing jaws. The aim of the invention is to facilitate the introduction of the webs in discontinuous operation. The object of the invention consists in pressing together the two webs, which are wide apart, during the idle time by means of pressing jaws. According to the invention, this is achieved in that the webs are guided in a freely suspended manner, there being arranged below the packaging material table, at one side and externally, a stationary, spring-mounted pressing plate against which a pressing jaw mounted pivotably on the opposite side behind the second web comes to bear when a supply roll has been used up. <IMAGE>

Title: Method for screening against underground vibrations, a device for carrying out the method as well as a damping wall for use in the method
IPC: E02D31/08
Filed: 1985-05-04
Abstract: In a method for screening against underground vibrations, firstly a ground opening is excavated, which runs transversely to the direction of spreading of the vibrations and into which vessels are then inserted and arranged in a row one behind another. These vessels are subsequently filled with a vibration-damping filler, a continuous damping wall being formed, which ensures high screening of the vibrations and can be provided simply and economically. Instead of the vessels, prefabricated parts can also be introduced and arranged next to one another or a filler made of vibration-damping material can be filled in to form the damping wall. Finally, the ground openings can also be formed by a row of boreholes, into which a suitable vibration-damping filler can be introduced, as a result of which an essentially continuous damping wall can likewise be achieved, which ensures a reliable screening against underground vibrations.
