Patent DE-4233485-A1 (DE)
Title: Active suspension control with variable damping using processor - alters damping coefficient w.r.t. displacement of suspension and displacement of sprung mass
Inventor: SHIMIZU HIROYUKI
IPC: B60G17/015
Filed: 1992-10-05
Abstract: The suspension control monitors (1) the dynamic displacement of a sprung mass and the relative velocities of the sprung- and unsprung masses. The damping coefficient is increased above threshold values for the dynamics when the sprung mass is moving in the same direction as the relative displacement. The damping coefficient is varied progressively to adapt the suspension better to the road conditions. A CPU (4) processes the displacement signals and generates control signals for a stepping motor to vary the damping coefficient. A low pass filter eliminates high frequency vibrations. ADVANTAGE - Adapts to road-speed conditions, improved stability and passenger comfort.

Title: (Protective) seat cover made of leather for cars
Inventor: DEJAN GUSTIN
IPC: A47C31/11
Filed: 1993-02-17
Abstract: Although car accessory shops/retail outlets have protective seat covers made of material or fleece for cars they do not have a (protective) seat cover made of LEATHER for a car . After due consideration I have decided to produce leather car seat covers in good quality leather with the advantage 1. of being breathable, 2. of sewing together hard-wearing and flexible leather in order to obtain and to give optimum support and strength. To manufacture leather car seat covers in various colours and designs so that the customer has the best possible choice. If it is desired to have leather seats in the interior of your vehicle a new car has to be bought with special trim or leather seats, which is very expensive. With leather (protective) seat covers for cars there would be a greater choice and, above all, at a much more cost-effective price than for a new car with special trim or the like.

Patent DE-4310899-A1 (DE)
Title: Hydraulic by-pass valve
Inventor: STRIEKER NORBERT
IPC: F15B13/01
Filed: 1993-04-02
Abstract: The present invention relates to a hydraulic by-pass valve, the control spool of which is controlled by a pilot-control valve. Such a valve is to be improved to the effect that a smooth connection between the pressure line and the tank line is achieved so that the pressure oil flows uniformly. For this purpose, the control spool is provided with a choke spool, the outside diameter of which is smaller than the inside diameter of the control-spool axial bore enlarged in this area. In addition, the choke spool is provided with an axial choke bore. If the pilot-control valve is opened, the pressure oil flows out of the rear spring space through the choke bore into the pilot-control passage so that the control spool is moved in a delayed manner into the open position. If the pilot-control valve is closed, the pressure oil flows through the annular gap and through the choke bore into the spring space so that the control spool is moved with a rapid reaction into the closed position.

Patent DE-4315317-A1 (DE)
Inventor: KUERTEN HERIBERT DIPL ING
IPC: F01K13/02
Filed: 1993-05-07
Abstract: A control equipment for automatically controlling power units in an electrical power supply system includes a control unit being connected through a data transmission element to each power unit to be controlled, for receiving power-unit-specific measured variables and for emitting power-unit-specific reference variables. The control unit evaluates the measured variables cyclically by taking account of stored values and defining a control instruction for one or each power unit. Particularly effective control of the power units is possible through the use of such a control equipment, with both a predetermined reliability level of the power supply or electricity supply being maintained and an unnecessarily high power reserve being avoided.
Patent DE-4318841-A1 (DE)
Inventor: BELTHLE HEINZ
IPC: B24B19/12
Filed: 1993-06-07
Abstract: The camshaft is clamped in a workpiece receiver and is rotated around its longitudinal axis while a grinding tool is moved in cutting contact with one or more cams 18a essentially radially to the cam rotational axis in the sense of generation of a desired cam shape. A grinding tool 19 with a grinding surface which is wider than, in particular at least twice as wide as, the cam surface to be ground is employed for grinding the cams. The cams are ground in succession by different axially adjacent grinding surface sections 43a, 43b and 44a, 44b of the grinding tool 18. The service life of the grinding tool is increased considerably and if a grinding belt 19 is employed as the grinding tool, its loading capacity is increased. Both features improve the profitability of the machine and of the process. A grinding disc may also by used instead of a belt. <IMAGE>

Title: Toilet wheelchair for severely disabled persons
Inventor: GAAL VIKI
IPC: A61G5/10
Filed: 1993-09-23
Abstract: This toilet wheelchair can be produced from various wheelchairs of conventional design, by means of detachable fixture of the seat lid under the toilet seat, in such a way that the disabled person sits on a toilet seat and seat lid at the same time and that when the seat lid is removed the disabled person remains sitting on the toilet seat. Such a wheelchair makes it possible to get a disabled person, sitting in the wheelchair and wearing special underwear of conventional type, onto the toilet without lifting them. The soiling of the toilet seat and the chair frame during the bowel movement is completely ruled out by a protective element detachably fastened under the toilet seat. If the basic wheelchair is sufficiently comfortable, the disabled person does not need to be transferred to another chair after being in the toilet. The wheelchair is urgently required in the care of disabled persons at home, especially if the family consists of two old people, one of whom is severely disabled, but it can also be used in many other cases.

Patent DE-4410127-A1 (DE)
Title: Revolution rate measuring device
Inventor: HINZ MICHAEL
IPC: G01P3/64
Filed: 1994-03-24
Abstract: Two contactless sensors detect the contour of a rotating part with a fixed rotation axis and convert it into two electrical measurement signals, from whose phase angles the revolution rate is determined. The sensors are arranged radially at a fixed but adjustable angle to the rotation axis. The time is measured for a given contour point to move between the two sensors, at which equal amplitude measurement signals (M1,M2) are generated at the time interval (t2-t1) apart. The measured time is a measure of the instantaneous revolution rate. The measurements are always made at the same contour point and are thus independent of the global contour of the rotating part.
