Patent DE-4317245-A1 (DE)
Title: Car headlamp - has light stop between bulb and lens with two stepped edges of different angles to vertical
Inventor: CEJNEK MILAN
IPC: F21V11/00
Filed: 1993-05-24
Abstract: The headlamp has a reflector, a light source, a light stop and a lens. The light stop has two stepped edges, one either side of the centreline, the steps being inclined at different angles. On the nearside step, the angle is steeper than on the offside step. Numerically, the respective angles are 60 and 75 degrees from the vertical respectively. The nearside step is closer to the centreline than the offside step. The heights of the steps are proportional to the distance of the stop from the lens plus a third of the maximum lens thickness. The light source lies slightly below the reflector axis, as does the axis of the lens. ADVANTAGE - Increases light intensity on nearside road edge.

Title: Material for electrical contacts consisting of silver@ or silver@-alloy matrix - incorporate tin oxide and other oxide(s) and carbide(s), has longer service life but is less brittle than other materials
Inventor: BEHRENS VOLKER DIPL PHYS DR
IPC: C22C32/00
Filed: 1993-06-09
Abstract: Material used in the mfr. of electrical contacts consists of a predominantly Ag-contg. alloy matrix with regions of Sn oxide and other oxides and/or carbides. Other oxides and carbides are contained in the Sn oxide regions and/or in the boundary regions beteen Sn oxide and the Ag matrix. The total content of other oxides and carbides corresp. to 40 wt.% of Sn oxide content. Other oxides and carbides are those of Mo, W, Bi, Sb, Ge, V, Cu, or In. The Ag matrix contains none of the named other oxides and carbides (apart from possible soluble cpds.). The material is produced by mixing powdered Ag or Ag-alloy with a powder contg. Sn oxide plus other oxides/carbides, compressing and then sintering. Total material content of Sn oxides plus other oxides/carbides is 5-20 wt.%, pref. 8-15 wt.%. The concn. of other oxides/carbides in the Sn oxide regions (w.r.t. total Sn oxide content) is min. 0.01 wt.% and max. 10 wt.%, pref. 5 wt.%, esp. 2.5 wt.%, the most advantageous concn. being 0.1-1.5 wt.%. The Sn oxide regions in the material are less than 100 microns, pref. less than 10 microns, but not less than 0.5 microns in dia. Sn can be completely or partially replaced by Zn. ADVANTAGE - The material exhibits similar thermal behaviour to other contact materials, but is less brittle and has an increased service life.

Title: Toggle press and method of controlling the plunger movement
Inventor: VERHOEFEN ULRICH
IPC: B30B1/16
Filed: 1993-06-16
Abstract: The invention relates to an toggle press, consisting of a press column and a plunger movable between a top and bottom dead centre position. The plunger is connected via a toggle system to at least one pressure-medium cylinder containing a double-acting working piston and if need be to further secondary cylinders, the working piston (10) being designed as a hollow piston and having a drag rod (12) in its interior. The drag rod (12) is in contact with a hydraulic valve (3) attached above the working piston (10) and coaxially to the latter. In its "open position", the hydraulic valve (3) connects the pressure space (5) located above the piston-base side to a tank (6). In its "closed position", the hydraulic valve (3) connects the pressure space (5) and the annular space (7) to one pressure line (8) each. In this arrangement, a hydraulic pump (9) is connected to both sides of the pressure-medium cylinder as well as to an actuating piston (24) at the hydraulic valve (3). When the drag rod (12) moves upwards in the direction of the top dead centre, the actuating piston (24) holds the hydraulic valve (3) in its "open position" until the working piston (10) has reached its maximum acceleration. Furthermore, the invention relates to a method of controlling the plunger movement via a working piston moving in a double-acting pressure-medium cylinder of a toggle press between a top and bottom dead centre, the plunger first of all ... by increasing the pressure on the ...

Patent DE-4322373-A1 (DE)
Title: Gasket esp. for pharmaceutical industry to seal glass-lined reaction vessels
Inventor: NYLAND PETER FRANCIS
IPC: B01J3/03
Filed: 1993-07-06
Abstract: The gasket comprises at least one gasket inert (24) and a gasket envelope (22) around the gasket insert. An overlap part (46) of the gasket envelope overlaps a radially outermost edge of an insert thereby to restrict, in use, inward movement of the envelope relative to the gasket insert. This is useful for sealing glass-lined reaction vessels as they can produce a suction effect which can suck the envelope into the vessel. The overlap portions prevent this. There may be a steel reinforcing plate (26).

The annular space has a shut-off device, which closes the annular space during the cold starting phase of the engine until the exhaust catalytic converter is heated up to its working temperature and can then be actuated as a function of the engine operation. <IMAGE>
Patent DE-4337794-A1 (DE)
Inventor: WALTER GERHARD DIPL ING
IPC: B62D137/00
Filed: 1993-11-05
Abstract: In the method 1 to n of several different manipulated systems E1 to En, on which all the same influencing variables act, are regulated. The control output ST_R determined by the regulation system is compared with a control output ST_ERW required to achieve the current controlled variable setpoint value under calibration conditions. The control output (ST_2 ... ST_n) for regulator-assisted controlled systems is determined as a function of the difference between control outputs determined in this way and the controlled variable setpoint value for a regulator-assisted controlled system (E2 ... En). This procedure has the advantage that controlled systems can also be manipulated with regulator assistance even if the current values of the influencing variables are not known through either measurement or calculation. Systems are intended to be particularly in automobiles and cover areas such as steering systems or injection systems. <IMAGE>

Abstract: The data are classified as more or less dangerous depending on the system values which they represent and, where data are unequal, are transiently processed further with the data classified as less dangerous. It is possible, especially with more than bivalent data, to list in a table the data with which further processing is to be performed transiently in the case of unequal data. This table can be used, even for further processing, to predict such data which exist in none of the participating partial control systems, e.g. the data from the previous processing period. The process can be used to advantage in both multi-computer systems and with linking circuits with redundancy.
