Patent DE-3711752-A1 (DE)
Title: Pressing disc for transmitting the pressing force of the ram of an extrusion press to the extrusion billet
Inventor: KOEDDERMANN HANS OTTO
IPC: B21C26/00
Filed: 1987-04-07
Abstract: A pressing disc consists of an annular sleeve with an expanded conical end portion and of a mandrel connected to the press ram and having a conical end portion. During the extrusion process, the end portion of the mandrel forces the conical annular sleeve apart such that the pressing disc (pressing pad, dummy block) engages without play in the container. Owing to the relative motion between the mandrel and the annular sleeve, some of the material to be extruded can get between the conical surfaces at the front end and can hinder them from springing back due to the elasticity of the material after the extrusion process. The intention is to form a pressing disc with which the change in diameter at the beginning and end of the extrusion process is retained. The pressing disc has a smooth outer end face and an annular free space starting from the central area of contact is formed between the contact surface and the end face of the press ram. This pressing disc allows deformation of its free end by force, while the rim of the pressing disc tilts and eliminates the play. As the pressing force decreases, the pressing disc returns to its initial position.

Title: Fastening for ladders in cable manholes
Inventor: FUCHS ALFRED DIPL ING
IPC: E06C9/02
Filed: 1987-04-11
Abstract: Ladders are necessary in cable manholes for using the manholes during inspection and repair work. Known types of fastening with brackets subsequently mounted by plugs or with rods loosely inserted into the manhole frame involve a lot of work or are unsafe. The novel type of fastening is designed as a plate which is inserted between two manhole components when placing the manhole and has prepared screw fasteners on the inside for the ladder. The fastening plate is either T-shaped or O-shaped in plan view. In the case of the T-shape, projections which constitute a displacement locking means are provided on the sections protruding on the inside and outside. In the case of the O-shape, the projections lie further to the inside and serve there as a connection to the concrete of the manhole frame (Fig. 1). <IMAGE>

Abstract: A rake for a circular sedimentation tank having a rotatable scraper blade arranged in the region of the tank base, which scraper blade is connected to an extraction unit for extracting the raked sludge along the length of the scraper blade, is to be flexibly designed with respect to adaptation to the different sludge production in individual sections of the scraper blade. This is achieved according to the invention by providing suction tubes (5), connected to the extraction unit (8), along the radially continuous blade contour (3, 4) (Fig. 1). <IMAGE>

Title: Method and apparatus for the automatic filling of a continuous casting mould
Inventor: LOTHMANN JOSEF
IPC: B22D41/20
Filed: 1987-06-22
Abstract: Method and apparatus for the automatic filling of a continuous casting mould with (steel) melt in which the melt (13) is poured into the continuous casting mould (18) in a controlled manner through a bottom outlet opening (14) of a launder (10) or of a tongue dish, the opening being closable by means of an automatically actuated plug (15) which, during the filling of the continuous casting mould (18), executes predetermined up and down movements (double arrow 45), in particular up and down movements dependent on the molten metal level (19) in the continuous casting mould (18), executing these movements counter to the action of an elastic element which urges the plug (15) into the closed position. The up and down movement of the plug (15) is accomplished by means of an actuating member (B) acting directly on the upper end of the said plug, the elastic element (A) urging the plug (15) into the closed position attempting to push the plug (15) into the closed position in a correspondingly increasing manner as the temperature increases. As the elastic element (A), use is preferably made of closed gas-pressure springs (48), while the actuating member (B) is preferably formed by open spring elements (49) which, as regards their design, correspond to the closed spring elements (48). <IMAGE>

Inventor: HEINRICH WULF-DIETER DIPL ING
IPC: H02P3/22
Filed: 1987-10-21
Abstract: The invention relates to a method for power distribution between a plurality of parallel-connected servo drive amplifier ballast circuits, and to a ballast circuit for servo drive amplifiers having a ballast resistor (5), which can be connected to the electrical power supply lines (8) of the servo amplifier (6) and can be pulsed by means of a switching device (3, 4), and having a fixed switching device response threshold (2) for limiting the intermediate-circuit DC voltage on an energy-storage capacitor (9) which is connected in parallel with the servo amplifier (6). The associated drawing shows an outline circuit diagram of such a ballast circuit. The invention is based on the object of creating a capability to operate a plurality of such ballast circuits from a common DC voltage busbar, irrespective of the number of shafts supplied. To this end, in the case of the ballast circuit according to the invention, the fixed switching device response threshold (2) of (each of) the ballast circuit(s) is increased by a voltage amount (UC), by means of a match circuit (1) whenever the ballast resistor (5) is pulsed, and is reduced again in the event of a load, with said voltage amount (UC) being dimensioned such that it produces compensation for the component tolerances of the fixed thresholds (2) of parallel-operated ballast circuits during the load duration, which is normal in servo operation, of the ballast circuit. <IMAGE>

Title: Semiconductor device
Inventor: ISHII TATSUYA
IPC: H01L29/423
Filed: 1988-01-20
Abstract: Conventional semiconductor storage devices having a high degree of integration have the disadvantage that a higher degree of integration cannot be achieved due to lack of space and that an inadequate covering capability of the steps of a contact hole leads to increased contact resistance values and connection resistance values. It is the object to eliminate these disadvantages. The semiconductor device according to the invention exhibits: a substrate 1 having a main surface with islands, the upper surface of which is flat, an electrode 4 formed around an upper edge of the island with intermediate dielectric gate film 7, a capacitor electrode 3 formed around the island with an intermediate capacitive dielectric film 9 and arranged at a distance from the gate electrode 4, and a doped source/drain region 8 which is formed on the upper surface of the island and in an area between the gate electrode 4 and the capacitor electrode 3.

Title: Vacuum switch having an external axial magnetic field generating device
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1989-05-03
Abstract: The invention is based on the object of introducing a new open winding arrangement, which surrounds the switching housing (2) externally, for the generation of an axial magnetic field. In this case, previously obstructive features, such as sensitivity to current forces, local distortion of the axial magnetic field or costly production, are intended to be avoided. The achievement of the object comprises a rotationally symmetrical arrangement of two open cylinder jackets (9, 10) together with associated inner (11, 12) outer (15, 16) connecting pieces. The open cylinder jacket can advantageously be developed to produce an open screw band with an alternating winding direction. The current forces are partially neutralised by the system symmetry and are partially absorbed by means of an enveloping body which surrounds the open winding bodies and is made of stainless steel (23). The distortion of the axial magnetic field is reduced by the rotationally symmetrical covering of the gap and wall of the winding bodies. The raw material for the open cylinder jacket turns or screw-band turns is cost-effective semi-finished product, namely sheet copper. <IMAGE>
