Title: Method and device for cleaning the inner surface of pipes
Inventor: SCHNEIDER HEINRICH
IPC: B08B9/04
Filed: 1981-03-20
Abstract: For the quick, convenient and nevertheless reliable freeing of inner pipe surfaces from deposited material over their entire length, with each to and fro action of the back and forth movement in the axial direction of the pipe of a cleaning tool attacking such deposited material, the deposited material is removed virtually over the entire inside diameter of the pipe. For this purpose, the device according to the invention has a cleaning head which can move back and forth inside the pipe. On its outside surface, protruding virtually radially from the latter, abrasive means are arranged in virtually uniform distribution over the circumference of the said surface. The distance between them and the inner pipe surface can be set. The effective outside diameter of the cleaning head can be set and preferably has for this purpose an inner adjusting tube, which is slit over its entire length, and an outer working tube, which bears ribs projecting radially away from said adjusting tube and provided with a slitting which likewise extends over its entire length and is radially in line with the slitting of the said adjusting tube. The slittings may in each case run parallel to the axis of the pipe or with an inclination with respect to the pipe axis.

Title: Process and device for the numerically controlled machining of a workpiece simultaneously with at least two tools
Inventor: KIRCHHOFER HEINZ
IPC: G05B19/18
Filed: 1981-04-28
Abstract: The path curve (24) along which the finishing tool has to move in relation to the workpiece is defined by programmed reference points (R1-R4) and, lying between them, determined intermediate points (S1-S7). The roughing tool, moving together with the finishing tool in relation to the workpiece in the common control axis (Z), is to cover a path (23) fixed by the programmed reference points (P1, P2). To be able to synchronise the movement of the two tools, the programmed reference points (P1, P2) of the path curve (23) for the roughing tool can, if need be, be shifted to the closest intermediate point (S2, S5) or the closest reference point of the path curve (24) for the finishing tool. In addition, for the path curve (23') for the roughing tool, the intermediate points (T1-T7) are moved to the intermediate points (S1-S7) of the path curve (24) for the finishing tool. The deviation of the path curve (23') covered by the roughing tool from the programmed path curve (23) is allowed, since it is not necessary to maintain the roughing contour exactly. Since no changes are made to the programmed data for the path curve (24) for the finishing tool, it is ensured that the required finishing contour is maintained. <IMAGE>

Patent DE-3124258-A1 (DE)
Title: Method and device for measuring and/or recording extremely small movements of a measured body, for example for measuring and/or recording the movement of a barometric cell of an aneroid barometer
Inventor: MOELLER CLAUDIO DIPL ING
IPC: G01L9/00
Filed: 1981-06-19
Abstract: The invention relates to a method for measuring and/or recording extremely small movements of a measured body, for example for measuring and/or recording the movement of a barometric cell of an aneroid barometer or of a bimetal strip etc., by means of an optoelectronic module, in particular a differential diode or a double photoresistor which interacts with a light beam emerging from a light source, the light beam being deflected by the movement of the measured body and the deflection being measured and/or recorded. In this process, the deflection of the light beam is compensated again on the basis of the movement of the measured body by tracing back to the light source and the tracing-back movement is measured and/or recorded. The tracing-back of the light beam takes place in an enclosed, preferably at least partially optoelectronic control circuit.

Title: Brake lining spring for a spot-type disc brake
Inventor: OSHIMA HARUMI
IPC: F16D65/097
Filed: 1981-06-23
Abstract: The invention relates to a specially designed brake lining spring for a spot-type disc brake, the latter being provided with a brake anchor plate which has two limbs which are arranged at a distance from one another in the circumferential direction of a rotatable brake disc and each overlap the outer circumference of the brake disc, in each case defining brake lining guide parts which are each interrupted by grooves in the limbs of the brake anchor plate, and the disc brake furthermore being provided with two brake linings, which are arranged on the opposite sides of the brake disc and are displaceably mounted on the brake lining guide parts, and with a brake caliper displaceably mounted on the brake anchor plate. In this arrangement, the lining spring provided between the brake anchor plate and the brake linings is held on the brake anchor plate and has a stop which limits the displacement at least of one of the brake linings in the direction of approach to the brake disc. This provides an effective means of preventing the respective brake lining from slipping out of the brake lining guide parts during the assembly of the disc brake or the replacement of the brake linings and thus allows the abovementioned operations to be carried out rapidly and reliably.
Patent DE-3124703-A1 (DE)
Title: Method for producing substance carriers, in the form of grids, for lead-acid accumulators
Inventor: AUMAYER RICHARD DIPL CHEM DR
IPC: H01M4/73
Filed: 1981-06-24
Abstract: A method is proposed for producing light carriers in the form of grids, which are used for accommodating the electrochemically active substance of lead-acid accumulators. The substance carrier in this case consists of an electrical conductor in the form of a wire or of a grid which is stiffened by means of plastic, anchored and possibly divided into fields for accommodating the electrochemically active substance. In this case, the plastic is at least partially superimposed on parts of the electrical conductor from both sides, the plastic layer of the first side being connected to the plastic layer on the second side. In a preferred embodiment, a network consisting of plastic and/or metal is placed on one side of the electrical conductor and is attached to the electrical conductor by means of the said plastic. Metal-mesh grids are particularly suitable for use as electrical conductors and are preferably connected to one another in the form of a strip in the context of production of these substance carriers. A first layer of plastic strips which run parallel to one another is initially extruded onto an operating base (for example a conveyor belt) for advantageous manufacture of such substance carriers, the electrical conductor is then placed on this strip and the second layer of plastic strips is then supplied to the electrical conductor, and the superimposed (congruent) plastic strips are finally connected to one another by means of at least one stamping device, are anchored to the electrical conductor and are calibrated in height; alternatively, a plastic mesh can also be added to the substance carrier before or after the electrical conductor is fitted. <IMAGE>

Title: Process for casting steel, in particular steel ingots
Inventor: LANGHAMMER HANS-JUERGEN DR ING
IPC: B22D7/00
Filed: 1981-08-18
Abstract: The invention relates to a process for casting steel, in particular steel ingots, for the subsequent production of roughed slabs, billets, sheets etc. in a subsequent rolling operation. In this process, a quantity of molten steel is poured into a metallic mould. The mould is surrounded by a jacket consisting of thermally insulating material. After heat equalisation, the steel ingots, which are still hot (at over 1000 DEG ) due to the insulation, are rolled down at their own heat. According to the invention, relatively thin-walled permanent (chill) moulds are used, the dimensions of which are matched in such a way to the solidification heat of the quantity of molten steel to be poured in that, after casting, the mould and the quantity of steel poured in are at a temperature of preferably above 1100 DEG C but below the liquidus temperature of the mould. <IMAGE>

Title: Variable plant troughholding device
Inventor: PETRICK GERHARD
IPC: A47G7/04
Filed: 1981-09-04
Abstract: This plant troughholding device is suitable for accommodating one or more plant troughs. At the same time, it is ensured that the clamping device of the plant trough-holding device is adapted to the particular underlying constructions. Different sizes of plant troughs have no influence on the function of the plant trough-holding device. By displacement of the corresponding angle pieces, plant troughs of any size can be accommodated. The hole patterns, starting at different corner distances, in the base element (Figure 1.1) and the associated angle pieces (Figure 1.2, 3, 4) afford a parallel plane fixture. The angle pieces (Figure 1.2, 3, 4) have equal-length legs and the hole patterns are the same in all angle pieces. The hole patterns start from the angle-piece corner (1.5) at different corner distances, as a result of which adaptation to different underlying constructions (1.6) is possible. <IMAGE>

Title: Measuring and control device for the flow of a liquid in a conduit
Inventor: EWE KURT
IPC: G05D7/06
Filed: 1982-03-19
Abstract: In a measuring and control device for the flow of a liquid through a conduit, a rotating volumetric meter is used, the rotor shaft of which is connected to a driving or braking device, preferably an electric motor, controllable by an actuating signal. The unit thus formed is a combined measuring and adjusting device since the flow can be simultaneously measured and controlled. In liquid circuits with pressure feed, in particular in circuits carrying the heat transfer medium in heating systems, the units can be used instead of thermostatic or manually operated control valves and controlled using a room temperature-dependent actuating signal. In these applications, braking devices, preferably electric or magnetic eddy-current brakes, have merely to be provided in the units. The invention is used in heating systems, in room temperature control and in the calculation of consumption and amounts of heat. <IMAGE>

Title: Braking arrangement for vehicles in underground mining operations
Inventor: ANTHOFER HORST DIPL ING
IPC: B61H7/12
Filed: 1982-07-17
Abstract: The braking arrangement (12) according to the invention has brake cylinders (13) lying transversely to the vehicle (7) and having cones (19) at their ends. The brake cylinders (13) are pressurised hydraulically by integrated application cylinders and expand under the influence of compression springs. The contact rollers (32) of brake levers (34, 35) pivotable in vertical planes rest against the end cones (19) of the brake cylinders (13). When the brake cylinders (13) are displaced, the rollers (32) move on the cones (19) and thereby pivot the brake levers (34, 35), with the result that the brake shoes (15) come to rest against the horizontal flange (5) of the running rail (3). The transverse arrangement of the brake cylinder (13) in conjunction with the cones (19) ensures a uniform braking force on all the running rails (3) while the hitherto necessary expenditure involved with brake cylinders arranged in the longitudinal direction of running rails and with brake levers pivotable transversely thereto is halved.
