Patent DE-4340073-A1 (DE)
Inventor: HUHN HANS-ULRICH
IPC: C25D5/44
Filed: 1993-11-24
Abstract: A sliding element has a bearing metallic layer (2) made of aluminium or an aluminium alloy which bears on its side facing the sliding surface a galvanically produced tin layer (4) bonded to the bearing metallic layer (2) by a very thin alkaline, halogen-free layer of zink, copper, nickel and iron immersion deposited (3) on the bearing metallic layer. To produce such sliding elements, a highly-alkaline immersion bath is used containing salts of zink, nickel, copper and iron mainly cyanide-based. After the immersion treatment, the sliding element blanks are rinsed with considerably carbonic acid-free deionised water. During a first tinning step, the sliding element is treated in a bath at a temperature between 20 and 26  DEG C, with a current intensity from 2 to 3 amperes/dm<2> and for a duration of exposure of at least one minute.
Patent DE-4341959-A1 (DE)
Title: Integrated circuit with improved wiring
Inventor: POPPE MARTIN
IPC: G06F11/22
Filed: 1993-12-09
Abstract: The integrated circuit (5) has inputs (6) connected to its elements (8,10) pref. gates or flip-flops, which are connected to further elements (9,11), pref. gates or flip-flops, via adjacent electrically conducting tracks (12,13). The further elements are connected to the outputs (7) of the integrated circuit. For a defined input loading two adjacent tracks have voltage states corresp. to different logic states. When the two tracks are short circuited they adopt a common potential which leads to defined logic states in the further elements. A short between the tracks is thus detectable from the output signals.

Title: Two stage safety clutch for shaft
Inventor: QUITER ERNST-AUGUST
IPC: F16D1/08
Filed: 1994-02-18
Abstract: The clutch has a first clutch (1) which disengages the drive at a first threshold torque and an in line second clutch (2) which disengages the drive at a lower threshold torque.

Title: Device for fastening two components together
Inventor: GOEHLE ROLF ING GRAD
IPC: F16B5/06
Filed: 1994-06-15
Abstract: The device fastens two components together, for example the lower housing part of an electric apparatus, e.g. a faulty current fuse, to the upper housing part. The device prevents separation or opening without damage. An elongate, plastic deformable tightening part (12) is provided. This has a first hammerhead extension (13) at one end and a second hammerhead extension (14) at the other end. The first extension (13), after being inserted into an opening in the first component (11) and rotated, engages behind a return spring in recesses (25,26), and is thus fixed in the first component (11). The second extension (14) is rotated further with a tool and engages behind a return spring in the second component (10). The tightening part (12) thus acts as a screw and the two widened ends (13,14) clamp the two components together.
Patent DE-4423632-A1 (DE)
IPC: B27N3/08
Filed: 1994-07-06
Abstract: The preheating process is carried out by a climatized fluid of air and water vapour. The fluid passes through the dispersant material, and is at a temperature, which is higher than the dew point by the dew point differential. Fluid volume, dew point, and dew point differential are chosen, so that the prechosen preheating temperature for the dispersant is achieved. There may be some condensation in the dispersant. The humidity of the warmed dispersant can be adjusted by additional processes. The fluid temperature is below 100x, and the fluid has a relative humidity of approx. 30%.

IPC: G01S7/41
Filed: 1994-08-18
Abstract: A process is disclosed for determining the position and/or the displacement in time (trace) of a (radar) target surface by means of a radar installation. A predeterminable number M of the largest echo amplitudes is first determined for the target surface, as well as the corresponding resolution cells (distance and azimuth co-ordinates). By averaging the distance and azimuth co-ordinates of the selected resolution cells, co-ordinates are determined for a reference point that is stable in space in relation to the target surface. This reference point is used for locating and/or tracing objects, in particular ships.

Title: Wind power generator method and device
Inventor: WIMMER ULRICH DIPL ING
IPC: F03D9/25
Filed: 1994-12-02
Abstract: A wind power electrical energy generation method and device has the wind flowing through the open section of a vertical shell tapering downwards. Air is sucked in at the bottom through several openings and is used to drive a rotor. Inside of the shell there is laminar flow and the wind speed is increased by a flat lid at the top of the shell. The energy for electricity generation is created exclusively by the under-pressure produced by the wind. The air is passed out in a region remote from the upper opening and preferably with a lower speed than that near the rotor. The flow of air sucked in is controlled automatically by electronic or mechanical means and depends on the instantaneous wind speed.
