Title: Method for regeneration of automotive clutch
Inventor: BETT PETER
IPC: F16D13/71
Filed: 1996-09-26
Abstract: Clutch linings (7,8) are held by a spring (5) against a clutch housing (1) and are held in place against a rest-plate by a locking fixture (4). The clutch efficiency is restored following wear by removing a thickness (X) from the rest-plate surface, corresponding to the thickness of clutch lining wear.  The clutch housing is then pressed in towards the press-plate (3) at the same height as the press plate by the same dimension (X) in a circular pattern. The clutch housing has a circular groove (9), with location drill holes (10) for the membrane spring in the groove-base.

Title: Flap valve
IPC: F16K41/10
Filed: 1996-10-04
Abstract: The valve consists of a housing (1), flanges (12,13), a valve a valve disc (2) and a valve shaft (3). The axis of the valve shaft undergoes successively a movement in a straight plane, then undergoes a rotary movement, then about the valve axis connected with a movement of the valve axis on a curved plane. A packing bush (6) is connected to the housing by a folding bellows (7), which forms a pressure-tight seal, and is secured against rotation. The stop bush can have two degrees of movement relative to the housing. The movement of the valve shaft is automatically controlled by the movement of a shaping body (19) in a groove (21). The drive force at the start of the opening movement perpendicularly intersects the shaft axis and is parallel to the axis.

Abstract: The invention concerns an acoustic transducer for the ultrasonic range, which transducer can be used both as a transmitter and as a receiver. By using a piezoceramic transducer element an extremely flexible transducer which is easy to produce, has a broad band width and ensures technological repeatability can be provided. It has been shown that an acoustic transducer for the ultrasonic range satisfies demands when the front and rear surfaces of the active transducer element which are covered with electrodes are structured such that a highly unhomogeneous distribution of the electrical field is attained. In one possible configuration the active transducer element consists of a polarized piezoelectric block on the rear surface of which very deep incisions or grooves are provided, the front and rear surfaces of the block being provided with an electrode covering.

Title: Gas-turbine blades crack testing and crack depth measurement
Inventor: UHL DIETER DIPL ING
IPC: G01N27/90
Filed: 1997-03-14
Abstract: A method for noise/interference-free detection of cracks and for measuring the depth of cracks in electrically conductive material with at least 0.1-1.0 mW/cm resistivity by using a measurement device with eddy current-sensing coils at a specifiable measurement frequency with evaluation, in which axial gradiometer-measurement probes with transformer circuit, or a discrete coil in a parametric circuit, are used. A test control body is used and comprises of material the same as that to be tested, and having slots formed in its surface with given different depths and given width of the individual slots. Depth-of-crack measurement is carried out on the test body by establishing a calibration curve for the dependency of the measured signal amplitudes on the respective depths of the generated slots. Measurement is then carried out, with an unchanged measurement arrangement/choice of coils on the test item to obtain measurement of this test item, which are then compared with the measurement results of the test control body with the calibration curve for determining respective crack depths present in the material of the test item.

Inventor: RAUSCH GEORG
IPC: E02F9/22
Filed: 1997-08-11
Abstract: The invention relates to a hydraulic control device for a mobile machine, especially for a wheel loader, comprising at least one hydraulic cylinder for moving the machine, a directional control valve for controlling the pressure medium channels between a pressure chamber of the hydraulic cylinder, a pressure medium source and a tank, a hydraulic accumulator which can be connected to the pressure medium source by a filling line, and a control valve. A connection between the hydraulic accumulator and the pressure chamber of the hydraulic cylinder can be opened and closed by means of said control valve. The aim of the invention is provide a hydraulic control device of this type with an added means of preventing the machine from falling down. To this end, a deblockable locking valve is provided upstream from the pressure chamber of the hydraulic cylinder, opening out into the pressure chamber. Said locking valve can be opened when the directional control valve is activated for the pressure medium to flow out of the pressure chamber to the tank, and when the control valve is activated to create a fluidic connection between the pressure chamber and the hydraulic accumulator. This enables the pressure chamber in the hydraulic cylinder to be blocked off whilst ensuring its connection with the hydraulic accumulator in order to dampen pitching oscillations.
