Patent DE-4114734-A1 (DE)
Inventor: GIERS BERNHARD
IPC: B60T8/00
Filed: 1991-05-06
Abstract: A circuit arrangement for a vehicle with electronic anti-lock regulation has circuits for the individual regulation of the braking pressure cycle in the wheel brakes on a vehicle axle and to limit the yawing moment resulting from differences in braking pressure. In addition there are circuits (6) which detect the pressure reduction signals (PA1, PA2) individually and determine the pressure difference DA12) therefrom. With different frictional values ( mu -split), the average pressure release gradient on the high-pressure wheel is varied dependently upon the pressure difference (DA12) and the vehicle deceleration. At the moment when the "yawing moment peak" occurs, i.e. immediately before the low-pressure wheel returns to the stable region, the braking pressure at the high wheel is reduced by a value depending on the vehicle deceleration and the pressure difference.

Title: Adjustable control valve for vacuum lifting pad - has bore restricted by transverse grub screw providing additional fine adjustment
Inventor: LEWECKE ERNST
IPC: B66C1/02
Filed: 1991-07-12
Abstract: The control valve fits between the vacuum chamber and suction pads of a vacuum lifting system for sheet and plate. It consists of a cylindrical body (1) with a stepped bore (3a, 3b) and an adjusting sleeve (5) which screws onto the body to form an adjustable chamber (5a) at the end of bore (3).

Screwing radially into the smaller diameter bore (3b) of cylindrical body (4) is a conically ended grub screw (1B). The screw can be adjusted to restrict the bore and thus provide an additional fine adjustment of the suction force. ADVANTAGE - Simple, sensitive control.

Inventor: SCHMELTER DIETER
IPC: G11B27/34
Filed: 1991-07-23
Abstract: A computer-controlled, fully automatically running high-speed test process for the quality control of 1:1 copying lines of copied media, for example video cassettes, is described. In this process, following the recorded information, a test signal comprising an item of audio information and/or an item of video information as well as an indentification of the copying recorder, is recorded onto the duplicating media. Subsequently, the copied media are passed in individual blocks to a number of test recorders (1-20), which are connected via an analyzing unit (21) to a checking unit (26) and a computer station (27), the test information being successfully searched for and tested, whereupon subsequently the tested medium is rewound, and the test cycles follow one another without any time in between them. In this way a fully automatic testing of a multiplicity of copied cassettes is possible in a very short time. The detects established are output on a label printer (28) and can be stuck on the copied medium, allowing the defect to be pursued. <IMAGE>

Title: Structured conductor track mfr. from high temp. superconducting layers
Inventor: ZANDER WILLI
IPC: H01L23/498
Filed: 1992-02-14
Abstract: A lacquer coating is applied to the surface of a suitable substrate in the regions intended for the high-temp. superconducting (HTSC) tracks. Then an inhibiting doping material (5) is vapour-deposited on the entire surface of the substrate followed by an insulating layer (6). The surface regions intended for the superconducting tracks are then cleared by lifting off the lacqueer mask. After deposition of the HTSC layers. On the substrate with annealing, the HTSC layer becomes an insulator on the doped substrate surface. On the undoped substrate surface the HTSC layer forms the superconducting track (7) by epitaxial growth.     To prevent the superconducting properties of HTSC structures from being adversely affected by the production process, some of the substrate material from the unlacquered substrate regions is removed after the lacquer coating has been applied. Thus HTSC tracks (7) are insulated from the doped but relatively higher substrate surface regions bearing the insulating layer (6).

Title: Method and apparatus for coating workpieces by means of roller weld surfacing
Inventor: SCHMITT-THOMAS KARLHEINZ G PRO
IPC: B23K11/06
Filed: 1993-03-02
Abstract: The invention relates to a method of coating workpieces by means of roller weld surfacing, in which a workpiece (1) and a surfacing device (2) are arranged so as to be rotatable relative to one another, the surfacing device (2), which consists of a surfacing electrode (3) and a counterelectrode (4), being in contact with the workpiece surface (5) via the electrodes during the welding operation and being mounted in such a way that the surfacing and counterelectrodes (3, 4), which are spatially separate from one another, can roll on this workpiece surface, and in which weld metal is fed during the welding operation via a weld-metal feed line (22) to the surfacing electrode (3) at a predetermined position (7) between surfacing electrode (3) and workpiece surface (5). So that heavy workpieces of large diameter can also be efficiently coated on the inside and outside over the entire periphery at several locations under the same conditions in such a way that no thermal distortion of the workpieces occurs, it is proposed that the relative rotary movement between the workpiece (1) and the surfacing device (2) be effected about a vertical workpiece axis (M) and that weld metal be fed simultaneously at several locations of the periphery of the workpiece. <IMAGE>
