Patent DE-4126868-A1 (DE)
Title: Partial discharge pulse detecting arrangement in gas insulated HV system - contains measurement points at boundaries of sub-regions of system which produce logical direction signals for evaluation of discharge location
Inventor: DUNZ THOMAS DR
IPC: G01R31/12
Filed: 1991-08-14
Abstract: The arrangement contains at least one measurement point (e.g. M1) for the electrical field of the partial discharges. The HV system is divided into at least two regions (e.g. B4) whose junctions are defined by suitable arrangement of measurement points. Each measurement point generates a logical direction signal defined by the propagation direction of a travelling wave from a distance pulse at the measurement point. An evaluation unit (A) decides whether a pulse occurs with in or outside of one of the regions from the logical direction signals. USE/ADVANTAGE - For accurate location of partial discharges in extended encapsulated gas insulated systems and separation of characteristic defect patterns.

Title: Bar-feed mechanism for machine tool - has endless transverse conveyors with distance pieces working between rollers of feed conveyor
IPC: B65G1/04
Filed: 1991-09-17
Abstract: The mechanism feeds back-stock to a machine-tool, particularly a shear, from transverse shelves with compartments for the stock formed by protruding arms.

Title: Rolling bearings with noise attenuation - obtained by means of an oil-filled gap in compound bearing races
Inventor: STEINBERGER WOLFGANG DIPL ING
IPC: F16C27/04
Filed: 1991-10-19
Abstract: The rolling bearing has at least one race (3) in the form of a cpd. hollow ring consisting of an inner component and a surrounding outer component to ensure reduced transmission of the noise produced by the rolling elements on the running track. There is a gap (7) filled with a liq. between the inner component (4) and the outer component (5) of the cpd. race. The hollow ring (3) with the gap (7) can be either the outer or the inner bearing race. The liq. in the gap is an oil. The rolling elements (2) are rolls. The cpd. rings are produced from two steel strips (one on top of the other) joined by a bonding agent by deep drawing and hardening processes. A layer of metal (tin, for example) can serve as a bonding agent. The bonding agent is evaporated and the resultant gap is filled with oil by dipping the ring into an oil bath. USE/ADVANTAGE - The bearing has a broad engineering application, in partic., in situations where low noise levels have to be maintained. It allows noise transmission to be reduced without, however, involving the drawbacks of known noise-attenuating bearings using elastic elements.

Inventor: PHILIPP MATTHIAS DIPL ING
IPC: G01L23/22
Filed: 1992-04-07
Abstract: The invention concerns a method for detecting knocking in an internal-combustion engine in which the signals from a knock sensor are fed to a signal processor. The invention also concerns a device for carrying out the process. To this end, the signals from the knock sensor are digitized, subsequently highpass-filtered and then integrated, and the signal thus obtained compared with two pre-determined limit values. Knocking combustion is considered to have been detected when both limit values are exceeded.

Title: Industrial sewing machine - has dual presser foot to accommodate double thickness material when stitching
Inventor: SCHOLL HANS
IPC: D05B27/04
Filed: 1992-09-14
Abstract: A process utilizes a sewing machine to stitch material of different thickness. The presser foot alternates with an advance foot, to determine the height of the material, and set the speed accordingly. As the greater height is encountered the speed is reduced, and when the height is reduced normal speed is regained. The machine is of a type which has preset controls, and these come into operation automatically when the duel presser foot arrangement (33,39) senses a difference in height of material on the table (7), i.e. (h1,h2). ADVANTAGe - The operator has only to set the controls on the machine and press the foot pedal to run. The speed will then be reduced automatically when thicker or double material is encountered.

Title: Adaptive anti=skid brake control circuit w.r.t. road surface - includes discrimination circuit to determine if road grip is uneven or road is bumpy when correction factor is included into braking sequence
Inventor: IIBOSHI JIRO
IPC: B60T8/173
Filed: 1992-09-25
Abstract: The anti-skid control circuit determines the type of road surface from the braking effects when the pulsed brake pressure is applied. If a bumpy surface, or varying grip surface, is detected then the anti-skid mode is adjusted to obtain better control and comfort e.g. the pulse pattern is changed as well as the brake pressure variation. The wheel slip is computed from wheel speed sensors and the brake pressure is corrected w.r.t. the pulse pattern and hysteresis factors. The correction applied depends on whether a poor road surface is diagnosed or a good surface. ADVANTAGE - Better braking control on poor roads, improved passenger safety and comfort.

Title: Electrical equipment stray radio field strength measuring method - measuring field strengths at critical frequencies previously determined by power measurements
Inventor: STECHER MANFRED DIPL ING
IPC: G01R29/08
Filed: 1992-11-26
Abstract: The field strength measuring method involves measuring stray radio field strengths at defined critical frequencies over a wide total frequency range. Variations in the azimuth of the device under investigation as well as the polarisation and height of the measurement antenna of the field strength measurement device are accounted for. The critical frequencies are determined by a previous measurement of stray radio power over the frequency range. A limit value LP = LF - RF is used for the power measurement, where LF is the limit value specified by standards and RF is the measured frequency-dependent level difference between the stray radio power and amplitude levels. ADVANTAGE  - Enables accuracy of stray radio field amplitude measurements to be achieved in minimal measurement times.

Patent DE-4312022-A1 (DE)
Inventor: PAULSEN JOERG
IPC: H02B13/025
Filed: 1993-04-13
Abstract: A switching cell arrangement is described, especially for medium-voltage switching installations, having at least two cells which are arranged adjacent and next to one another, each contain a switch and are closed at the top by pressure-relief flaps which are mounted such that they can pivot. The pivoting axes (shafts) of the pressure-relief flaps are arranged essentially parallel to one another. In the closed state, the pivoting axis of the pressure-relief flap of one cell faces the free end of the pressure-relief flap of the adjacent cell on the pivoting-axis side. In consequence, in the event of a defect in one cell, its adjacent cell on the pivoting-axis side is protected by the pivoting-up pressure-relief flap of the cell affected by the defect, and the pressure-relief flap of the neighbouring cell which is arranged on the opposite side of the affected cell cannot be lifted up on the side facing the affected cell by the suction occurring in the event of the defect being in the region between the pressure-relief flaps and the space cover (room ceiling). <IMAGE>
