Patent DE-19649063-A1 (DE)
Title: Blanking or forming press
Inventor: HOERNER BERND DIPL ING
IPC: B30B15/00
Filed: 1996-11-27

Patent DE-19707471-A1 (DE)
Inventor: WANING GERD DIPL ING
IPC: F27B9/12
Filed: 1997-02-25
Abstract: In the vicinity of the outlet (5) of the throughflow oven, i.e. approximately at the end of the cooling section (3), treatment gas is sucked out of the oven. The gas sucked out of the oven transfers heat in the direction of the annealing zone. The gas with reduced temperature is fed back to a position in the cooling section (3) spaced apart from the suction point and in the direction of the annealing zone. The feedback of gas is effected with a flow impulse directed in its main orientation in the direction of the oven outlet, so that a gas flow in the cooling section directed towards the oven outlet extends over the workpieces to be cooled.

Title: Particle detector using laser resonator, e.g. for detecting sub-microscopic particles in air
Inventor: SANDBERG JON C
IPC: G01N15/02
Filed: 1997-02-26
Abstract: The device has a laser resonator (13) and an optical pump source (19). The pump source excites a laser medium (11) to generate laser light in the laser resonator (13). A test region (29) is coated with particles. The test region is inside the laser resonator (13) in the path of the laser light. Thus light in the test region (29) is influenced in a predetermined manner by at least a proportion of the particles in the test region such that the affected light serves as proof of the proportion of particles. The laser medium is preferably a solid state laser medium (11). This may be e.g. a Nd:YAG or Nd:YVO4 or Cr:LiSAF crystal. The optical pump (19) may ne a semiconductor laser.

Abstract: The roller bearing for a vehicle clutch release mechanism has a rotating outer race (12) and a stationary inner race (2) coaxially surrounding an actuator (5) and forming a lubricated annular interior space (14) for holding the balls (15). The races (2, 12) have parallel support flanges (3, 13) which are perpendicular to the bearing longitudinal axis (11) and which are used for fixing the inner race (2) on the actuator (5), by means of a disc spring (6) inserted between the support flange (3) and a retaining element (7), and for fixing the outer race (12) on the clutch release lever. The interior space (14) is sealed on both sides of the balls (15) by a sealing element (20), which is fixed to one of the races, and a retaining element (7), the free ends of which are shaped to the contours of the associated races for providing enlarged axial or radial coverage while maintaining an annular gap (25, 26). Preferably, the sealing element (20) and the retaining element (7) consist of deep drawn sheet steel parts or of a plastic, especially a glass fibre-reinforced plastic such as PA 66GF.
Patent DE-19722886-A1 (DE)
Title: Spot-weld connection dismantling tool for re-cycling work
Inventor: AXMANN BERNHARD DIPL ING
IPC: B21D28/24
Filed: 1997-05-26
Abstract: The sheet is cut in a circle round the spot weld, etc. by means of a high impact energy punch (8) in cylinder shape and spherically depressed on its active face along the cylinder axis so the head of the connection centres the punch unit shortly before this engages the sheet in work. To obtain the cutting angle for punch cutting action, the punch face is milled out at 90 deg offset diametrally normal to the cylinder axis. At their apex the milling cuts are radiused to prevent notch-induced stress concentrations to give four-toothed geometry on the cutting face. This geometry gives rise on punch contact to symmetrically distributed peak stress points which in turn score or crack the sheet surface for progressive penetration of the sheet by the cutting edges of the punch. As it comes to rest on the sheet the punch should be guided in a circular cylindrical guide. The guided diameter of the punch exceeds that of the punch in the cutting area so as to prevent the punch jamming in the guide after the plastic deformation of the punch at the cutting edge in reaction to the sheet.

Continuous products with a cross section approximating their final cross section are produced by a joint action of forming elements mounted respectively on the casting wheel and the endless casting loop.
Patent DE-19737375-A1 (DE)
Title: Direct fuel injection system for vehicle IC engine
Inventor: IIDA KAZUMASA
IPC: F02D41/14
Filed: 1997-08-27
Abstract: The engine management system for spark ignition IC engines with fuel injection monitors the position of the throttle pedal to derive a first measure of engine torque. The gas flow during the suction phase of the combustion cycle provides a second measure of engine torque. The control system decides between two modes of fuel injection; during the suction phase for large torque and during the compression phase for small torque. The control ensures a smooth change over between the two modes of fuel injection. The control system derives two figures for the fuel/air mixture and amount of fuel injected, based on the two methods for calculating the engine torque. It also decides which mode of fuel injection is to be used and provides a smooth change in torque when changing from one injection mode to the other. The ignition timing can also be varied during the change over to assist in providing a smooth change.

Patent DE-19812086-A1 (DE)
Title: Hydraulic control valve, e.g. for control unit of vehicle brakes or suspension
Inventor: TAKAYAMA TOSHIO
IPC: B60T8/1761
Filed: 1998-03-19
Abstract: The hydraulic control valve has a plunger sliding over a fixed core inside a cylindrical bore in the valve housing. The inlet connection has a duct leading to a cross duct which is closed off by the plunger. As soon as the plunger starts to move the cross duct connects to the pressure space behind the plunger and provides hydraulic pressure to press pack the spring which holds the plunger in the closed position. A pressure relief bore through the plunger eventually equalises the pressure on both sides of the plunger and allows the spring to return the plunger into the off position. The other end of the core has a similar control bore which is shut off when the plunger moves.
