Title: Multipurpose device for cleaning and testing pipes
Inventor: MUELLER KLAUS DIPL ING
IPC: B08B9/043
Filed: 1987-09-29
Abstract: In the operation of the device according to the main patent, there is an increased risk of accident and the drive for the flexible conveyor belt breaks down if the cleaning element attached to its front end gets stuck in the pipe to be cleaned. The multipurpose device operates with much better reliability than the device according to the main patent. The main features of the multipurpose device (1) are a support (3) which is formed by stands (4, 5) and has assigned to it adjusting and clamping devices for the pipe (2) to be cleaned or tested, an adaptor (6) for receiving and introducing the cleaning or testing element (7, 8), which is movable back and forth through the pipe (2), into one pipe end and a belt drive or chain drive (9) which is arranged below the pipe support (3) and is intended for a flexible conveying element (10) which is designed as a plastic rod or pipe or as a chain stiffened by a spring strip and on whose front end the cleaning or testing element (7, 8) is mounted. The multipurpose device is preferably used in a fully automatic pipe production line. <IMAGE>

Title: Current path made of high-temperature superconductors
Inventor: KRIECHBAUM KARL DR ING
IPC: H01L39/14
Filed: 1988-02-04
Abstract: "High-temperature" superconductors consist of oxide ceramics and are too brittle for wires or other conductors which can be laid around curves and have a relatively large cross-section to be made from them. It has so far been possible to make flexible conductors from this material only in thin films which are only limitedly flexible and have a low current-carrying capacity. In order to make a current path from a superconducting material with a large cross-section which can be laid in any curves and can be produced economically, the invention provides for components to be formed from the superconducting material which have at least two contact surfaces which are parallel or form an angle. The contact surfaces consist of the thinnest possible metal contact regions. Such components can be connected together in series to form any desired conductors. <IMAGE>

Title: Separating device for fine wires
Inventor: EIDLING KARL
IPC: H05K13/06
Filed: 1988-03-15
Abstract: A separating device for cutting off fine wires (for example 60  mu m) during the automatic wiring of assembly printed circuit boards. In this case, it is intended largely to avoid compression, tension and bending forces on the wire ends. In addition, the neighbouring wire must not be damaged when the wires are at the minimum possible distance apart. The major part of the separating device consists of two cutting blades (1, 2) which are arranged like pincers and are combined in a clamped manner in a sprung blade support (3) to form an easily replaceable unit (line replaceable unit). A symmetrical cutting movement is achieved by means of a centrally arranged sliding link (5). The outward and inward movements are carried out by a column guide (7) with ballbearings. The axially displaceable pneumatic cylinder (8) produces both the outward and inward movements and the blade movement. Automatic wiring devices. <IMAGE>

Patent DE-3843869-A1 (DE)
Inventor: BECKER MANFRED DIPL ING
IPC: G01L5/13
Filed: 1988-12-24
Abstract: A force transducer for measuring tension and compression forces, having an essentially hollow bending body (39) which can be subjected to bending stress, the first end area of which can be fixed and into the second, free end area of which the force to be measured can be introduced at right angles to the longitudinal axis (40) of the bending body (39), and a measuring rod (76) which is rigidly connected to the bending body (39) in its second end area, extends freely into the interior of the bending body and carries at its free end at least one transmitter element (98) which faces at least one receiver element arranged in a fixed position, is to be constructed in such a way that as high a measuring sensitivity as possible appears. This is achieved by the bending body (39) having a relatively low bending resistance in the area in which the force is introduced, and by the bending resistance increasing towards the side of the fixed area. If the measuring sensitivity is only to be high for forces which lie in a preferred plane, the bending body (39) has a preferred direction with relatively low bending resistance. This directional selectivity can be further increased by a preferred arrangement of a magnet as transmitter element and a Hall sensor as receiver element.

Title: Ultrasound sensor system
Inventor: CRAIGIE NEIL DR
IPC: G10K11/26
Filed: 1989-04-20
Abstract: The invention relates to a method and an ultrasound sensor system for object detection or object surveying. With respect to previously available complex processing methods, which are partially governed by the weak echo signals present at the receiver end, the invention has the aim of creating a real-time method with good evaluation capabilities. The solution provided for this purpose provides optimum matching between the transmission system and the receiver system, simple processing on the basis of the propagation time differences of echo signals being possible as a result of a specific directional characteristic at both the transmitter end and the receiver end.

Title: Demetallisation and further treatment of used lubricating oils - from internal combustion engines etc., by continuous economical method in which heavy metals are reduced to within safety limits
Inventor: KIEL REINHOLD DIPL ING
IPC: C10M175/00
Filed: 1989-05-23
Abstract: This is a method and associated appts. for removing metal from used oils, and for their further treatment, and is partic intended for used oils from internal combustion engines and gearboxes.  The oil is mixed, in a mixing chamber, with water, additives, salts, and/or an acid, heated to 50-90 deg.C, and then seped, continuously in a three-phase decanter, into water-conting heavy-metal salt, water, and demetallised water-conting oil.  The water is recycled and the oil is further processed.  Variants claimed include the further processing of the oil and disposal of the heavy-metal salt, and the appts, used throughout. USE/ADVANTAGE - Heavy metals in used oils are a drawback in recycling the oils or in preparing them for use as fuel oils that comply with regulatory requirements. A known method for demetallising used oils is discontinuous, costly and time-consuming.  The proposed method, which is continuous, overcomes these difficulties, and gases from burning the reclaimed oil within heavy-metal limits.

Abstract: In such drilling, a preliminary hole (C) is drilled first, whereafter the drilling is interrupted. Such hole (C) is displaced from the intended drilling direction (A-B) by deflection of a boom (2) and/or feeding beam (5) due to forces upon contact with the rock face. Joints between the boom (2) and the beam (5) and/or the beam (5) in its longitudinal direction are released so as to move freely in order that the boom (2) and the feeding beam (5) would take a substantially strainless position, measured by gauges at the joints, and the angles ( alpha ,  beta ) of the joints and the position of the feeding beam (5) and the drill rod are measured. Thereafter the direction and distance from the preliminary hole (C) to the desired terminal point (B) is computed, and the drilling of the hole is completed, by adjusted portions of the boom (2) and/or the beam 5. <IMAGE>
