Title: Vehicle pneumatic suspension element
Inventor: ALBRECHT KLAUS DIPL ING
IPC: F16F9/05
Filed: 1995-10-20
Abstract: The pneumatic suspension element has an elastic, inflatable section (1) whose one end rolls over the mounting as it compresses. The internal pressure of the element is controlled and the suspension includes a damping element. The actual extension of the pneumatic element is controlled by an adjustable strap (4) between the mounting ends of the element. Its extension is controlled by a servo motor (2). The servo motor is electric, hydraulic or pneumatic and operates on a winder for the adjustable strap. A blocking clamp (8) secures the winder in the selected position. Alternately the extension of the pneumatic element can be controlled by a spindle driven element.

Patent DE-19548928-A1 (DE)
Title: Control system for motor vehicle four-wheel drive transmission
Inventor: SASAKI HIROKI
IPC: B60K23/08
Filed: 1995-12-27
Abstract: The transmission has a torque splitter (11) with a torque splitting clutch (11a) which controls the proportion of the torque transferred to the secondary axle. This proportion is controlled between zero and 50% of the total torque. Sensors (30) on the wheels provide data for the processor control. The torque is split in proportion to the mean speeds of the wheels on each axle.  To correct for any wheelspin the secondary axle sensors detect the slower wheel and provide a weighted coefficient to computed a weighted mean value for the wheel speeds. The difference between the weighted mean speed for the secondary axle and the actual mean speed of the primary axle provides a factor for determining the torque split. The weighted coefficient applies until the computed transverse acceleration exceeds a programmed value.

A clock selection code signal of the selected blocks is given in each of the NAND gates of the memory under the impulse generating circuit blocks to intermediately store the selected signal until a different block selection signal is chosen. The bit line selection signal takes up a first or a third level until this other block is selected.

Title: Isolation and matching transformer with liquid cooling
Inventor: KRUEGER MICHAEL DR
IPC: H01F27/10
Filed: 1997-01-16
Abstract: The transformer is divided into two or more temperature zones. First the coolant, such as mineral oil, flows through windings in an outer zone and is finally conveyed into an inner, hotter zone. Thus the coolant receives the heat of the transformer iron, and the heat losses from the part-windings, at a higher temperature level. Preferably an iron circuit is provided in a second temperature zone, which outputs its heat loss to the coolant.
