Patent DE-3314489-A1 (DE)
Title: Winding sleeve for rubber strip
Inventor: FROSCH HEINZ
IPC: B65H75/24
Filed: 1983-04-21
Abstract: The invention relates to a winding sleeve for rubber strip, especially for tread material for vehicle pneumatic tyres, which sleeve has sufficiently high lateral and radial stiffness to prevent the wound uncured tread material being pressed flat and which can be disposed on a winding mandrel. In order to permit post shrinkage of the wound rubber material without an impermissible tightening, it is proposed that the wall of the sleeve be separated substantially in the longitudinal direction so that circumference and diameter of the annular cylinder formed by it can be varied.

Title: Training apparatus
Inventor: RAUSCH REINOLD
IPC: A63B21/008
Filed: 1983-05-20
Abstract: The invention relates to a training apparatus for body building and/or fitness training which is equipped with at least one bearing surface for the body, or parts thereof, of the person training as well as with one or more supports which is/are assigned to the limbs of the body and is/are connected directly or indirectly to a changeable loading. In order to provide a training apparatus of this type which not only can be designed comparatively easily and in compact form, and thus can also be used in the domestic sector, but, furthermore, also permits development of force independent of the force of gravity, the invention proposes that the loading be formed by one or more cylinder/piston units which can be acted upon by pressure medium. The cylinder/piston units can be reversed. The apparatus is provided with a pressure-medium generator and, if appropriate, a pressure-medium storage means.

Patent DE-3331915-A1 (DE)
Title: Method and arrangement for measuring the mechanical properties of rock and minerals "in situ" for determining the rock-burst tendency of the deposit and the country rock
Inventor: SZECOWKA ZDZISLAW DR ING
IPC: E21B47/00
Filed: 1983-09-03
Abstract: To determine the rock-burst tendency of deposits, in particular coal seams, the mechanical properties of the minerals as well as of the country rock are determined. To this end, bores are made in the mineral, and deposited there is a measuring probe which has pressure plates which can be moved against the borehole wall. These pressure plates are acted upon by an increasing hydraulic pressure, or by a decreasing hydraulic pressure after a maximum value is reached, the pressure changes being continuously determined, compared and analysed. To this end, an inductive displacement-measuring device or a wire-strain-gauge pressure sensor is allocated to the probe or the hydraulic line. These devices are in turn connected to a computer via amplifiers and further processing units. In this way, the natural tendency of the seam to result in rock burst in the rock mass can be determined in good time and thus the particular state can be checked and if need be rendered safe or worked by suitable means. <IMAGE>

Title: Overload safeguard on clutches
Inventor: HELMES LUDGER DIPL ING
IPC: F16D7/04
Filed: 1983-10-01
Abstract: The invention relates to an overload safeguard on clutches functioning with a spring and a rotating element, the rotating element being arranged in an annular space (26) between drive and output element, the cross-section of which space is reduced at at least one point by means of a spring section (27) to a dimension smaller than the diameter of the rotating element and, in order to arrive at a low-wear design of simple construction which is technically easy to assemble, proposes that the rotating element be formed by a cam (29) assigned to the drive shaft (20), the apex (y) of which cam is greater than the dimension of the annular space (26) in its area of reduced cross-section. <IMAGE>
Patent DE-3339161-A1 (DE)
Title: Lotto mat
Inventor: KOERS HANS
IPC: A63F3/06
Filed: 1983-10-28
Abstract: The object of the invention is to facilitate the completion of the weekly lottery ticket by means of a lottery numbered template and a flat plastic body with a recess one millimetre deep (Fig. 1). Whereas the recess in the plastic body (Fig. 1) accommodates the lottery ticket exactly, the purpose of the template, which is exactly identical in size and on which the individual numerical fields of the lottery ticket are reproduced by means of perforations and from which individual numerical boxes can easily be pushed out with a pointed object, is that the numbers on the old lottery ticket can be transferred to the new one with no complications. The manner in which the "Lotto mat" operates is as follows: a lottery ticket is laid in the recess of the lower body and covered with the template, and the desired numbers are ticked through the previously removed boxes of the template. <IMAGE>

Patent DE-3340438-A1 (DE)
Title: Measuring arrangement for force measurements by means of strain gauges
Inventor: BRANDT WALTER DR
IPC: G01G21/07
Filed: 1983-11-09
Abstract: This measuring arrangement is provided mainly for direct measurements of the weight of objects to be weighed, such as, for example, bunkers, containers, platforms or the like. It consists essentially of a weighing cell in the form of a bolt cross made of metallic spring material, having a core piece (10) and four bolts (12, 13), cylindrical at least at their ends, extending from this at right-angles to one another, and bearing blocks (4, 5) which are located on the underside and top side of the weighing cell and on each of which two coaxial bolts (12, 13) are mounted positively, but so as to be rotatable to a limited extent and axially displaceable. Either bending or shearing of the bolts (12, 13) or the deformation of the core piece (10) can be measured on the bolt cross. Depending on the type of measurement, strain gauges are applied to suitable faces of the bolts (12, 13) or of the core piece (10). At all events, at least four strain gauges are used and are connected together in a way known per se to form an electrical measuring bridge. The detuning of the bridge connection, which is a measure of the size of the weight load, is measured. Since the mounting of the bolt cross allows limited displacements in both axial directions and rotations about these two axes, possible transverse forces cannot cause any measuring errors. <IMAGE>

Patent DE-3402256-A1 (DE)
Title: Housing for accommodating electronic components
Inventor: SCHMIDT CONRAD DIPL PHYS DR
IPC: H05K7/20
Filed: 1984-01-24
Abstract: The housing (1) serves as a casing for electronic components with a ceramic or glass substrate (9), preferably multiple circuits of thick-film or hybrid type, and comprises a housing bottom part (2) with a soldered or welded housing cover (3). The housing material provided is a sheet (4) of an iron-nickel alloy or of molybdenum, which is laminated on both sides with copper layers (5). Anti-corrosion layers (6) are provided by nickel or gold overlays. For the purpose of external connection of the housing (1) there are connection plugs (7) in the housing bottom part (2), which are enveloped by glass or ceramic sealings (8) to achieve electrical insulation of the plugs (7) or to seal the housing hermetically. The copper layers (5) serve particularly to spread the lost heat generated punctiformly during the operation of the electronic component (9), while the iron-nickel alloy or the molybdenum, owing to a thermal expansion coefficient similar to that of glass or ceramic material, ensures that any load reversal reactions of the housing do not lead to heat stress and thus achieves durable sealing and a secure attachment of the electronic component. <IMAGE>

Title: Circuit arrangement for the optimum utilisation of excess energy with the aid of electrochemical accumulators
Inventor: KOETHE HANS KURT DR ING
IPC: H02J7/00
Filed: 1984-02-09
Abstract: The invention relates to a circuit arrangement for charging electrochemical accumulators without limitation in the absorption of charging current, especially for power supplies which operate independently of a network, that is say in insular operation, and which are intended to ensure a continuous supply to the connected load. In the case of such power supplies, it often arises that the energy offered electrically by the energy converter cannot be absorbed and must be dissipated, because the accumulator has reached a charge state in which only a limited charging current supply is still possible, that is to say because it is approaching the fully charged state which must be brought about from time to time in order to maintain the storage capacity. The invention describes measures and devices by means of which energy consumption which is unrestricted in the context of the existing energy offer can be achieved by the accumulator and, nevertheless, the full charging which is necessary from time to time.

Title: Monolithic ceramic capacitor and a method for producing a large number of monolithic ceramic capacitors having flat connecting leads and a sleeve sheath
IPC: H01G4/228
Filed: 1984-09-05
Abstract: Method for producing novel, sleeve-sheathed, monolithic ceramic capacitors from a pair of lead-carrier strips 10 and 10a which are located opposite one another in parallel. Each capacitor body of a large number of capacitor bodies 18 is located in a clamped-in manner between the broad contact surfaces 15 and 15a of a lead pair 13, 13a, is soldered and sleeve-sheathed, while the leads 13 and 13a remain integral parts of the carrier strips 10 and 10a.

Title: Landing aid for helicopters
Inventor: TRAMPNAU ULRICH
IPC: B64D45/04
Filed: 1984-09-21
Abstract: A landing aid for helicopters in order to give the pilot audible and visual indications during simulated or actual autorotation landings in order to start and end the flare at the correct point in time which is specific to the helicopter. A normal landing is intended to be ensured thereby in order primarily to prevent the tail rotor striking the ground or water in a dangerous manner. In this case, a measurement system is used which uses a radar sensor on the tail skid to detect the altitude and sink rate of the helicopter and, at the same time, in particular, the vertical distance of the tail rotor from the ground, and supplies said information to a computer controller. The latter uses the measurements to derive the optimum point in time for the instruction to be given to the pilot. The use of a broad radar beam having a main beam direction pointing obliquely downwards/to the rear ensures that the vertical distance from the ground or water is always measured with high accuracy in all flare attitudes. The arrangement of the measurement unit at the tail makes the use of a high radar carrier frequency necessary, because of the volume and weight.
