Patent DE-19625174-A1 (DE)
Inventor: HARTUNG HANS
IPC: B21D51/44
Filed: 1996-06-24
Abstract: A process is disclosed for forming metallic lid bordering rings (20; 20a, 20b, 20c, 20d, 20e) with an inside opening (21) and a ring-shaped profiled border (20a, 20b, 20c, 20e). A cylindrical blank (10, VR) placed in the centre of several ring-shaped, concentrically joined tool segments (1 to 7) is pushed axially downwards (v0) by a outer tool segment (1) and deformed in a radial direction (v0') over a ring-shaped deflecting lip (5a) of a segment tool (5) located further inward in the radial direction among the concentrically joined tool segments (1 to 7). An upper segment tool (2) is held above the deflecting lip (5a) to define a gap (S) into which the blank (10; VR; HR) radially deformed (v0') inwards is pressed. This avoids the formation of cuttings inside (21) the thus produced lid bordering ring (20).

Patent DE-19707136-A1 (DE)
Inventor: JANDALI M ZOUHEIR DR
IPC: C08J9/00
Filed: 1997-02-22
Abstract: When foaming the hollow cavities of double- or multiple-walled components or foam-coating component parts with decorative surfaces so as to improve the haptic properties of said component parts, the invention provides for a mass introduced or applied in an unfoamed state to be foamed by means of microwave energy. To achieve high dielectric losses and to ensure that the heat effect is evently distributed and essentially restricted to the mass to be foamed, said mass is adjusted in a polar manner by addition of certain substances, such as conductive soot. Reflecting agents are used to improve the distribution and effect of the microwaves. This method ensures fully foamed hollow cavities and foam layers of uniform thickness.

Title: Oxygen sensor heater regulation unit for aircraft engine
Inventor: YAMASHITA YUKIHIRO
IPC: F02D41/14
Filed: 1997-07-09
Abstract: The heater regulation device, for an oxygen sensor, has an oxygen sensor (26) with a sensor element (34) which yields the oxygen concentration in the fluid flow. This has a heater (33) for warming the sensor element. The impedance of the sensor element (34) is received by a holding device. A heater regulation device (105), which is based on a negative feedback circuit, maintains the impedance of the sensor (33) at a nominal value by regulation of the energy supplied to the heater element.  A further device detects any variation of the sensor (33) which leads to an increase of its internal impedance, and this is coupled with a device that modifies the nominal impedance value maintained by the feedback circuit.

Title: Cylinder valve assembly for operation of inlet and outlet valves at cylinders of V-type internal combustion motor
Inventor: KUENNE ERNST-ANDREAS
IPC: F01L1/053
Filed: 1998-01-02
Abstract: The valve operation for a V-type internal combustion motor, synchronized with the piston movements in the cylinders, uses a different opening angle for the valves (17,27;18,28) in one row of cylinders (1,2) than for the identical valves (27,17;28,18) in the other cylinder row (2,1).

The closing time point of the inlet valve in both cylinder rows gives an identical position in relation to the bottom dead center in the cylinder row.
Patent DE-19810342-A1 (DE)
Inventor: MUELLER VOLKER DR
IPC: B21C3/14
Filed: 1998-03-10
Abstract: The invention relates to a method and device for the deformation by hydrodynamic drawing of multi-layer composite wire (8) by means of lubricant-supplied multiple drawing machines. According to said method, before the multiple drawing machine is started or restarted, directly in front of the drawing die (4) of each drawing stage a hydrostatic starting pressure acting on the drawing and other lubricant supplied thereto and on the multi-layer composite wire (6) is generated in the drawing slot by means of a heated pressure chamber (10) through which the multi-layer composite wire extends. In this way especially multi-layer composite wires (6) with a high-strength core and a soft sheath can be deformed in a high-quality manner, and during ongoing continuous drawing in a known manner hydrodynamic pressure conditions continue to be generated in the drawing slot by the entrainment of lubricant.
Patent DE-19811017-A1 (DE)
Inventor: KRAUS MICHAEL
IPC: A61B5/1473
Filed: 1998-03-13
Abstract: The device includes identical and/or differing sensors for single or continuous determinations. Each produces a signal related to the magnitude measured. A unit converts and transmits the signal. The sensor is implanted close to but outside the relevant blood vessel; a sample feed line reaches into the vessel. Preferred features: Unit overall size does not exceed 400 mu l, preferably 1500 mu l, especially 500 mu l and most especially 300 mu l. Clotting is initiated in the sensor, its course being followed by suitable tracking parameter(s). Numbers of sensors included, determine the same or different parameters. Each sensor is used only once and/or until it fails. The required electrical energy comes from an implantable battery, especially of the open variety; it alternatively arrives through an external transducer. The parameters to be determined react with sensitizer beads, which liberate singlet oxygen proportionately. This is measured by electrodes, converted and transmitted as a signal. The sensor beads are LOCI beads.
