The driving plate (10) has at least two integral brackets (14a), each one with a U-shaped recess, the recess being rounded so as to contain a ball (15a). The balls can rotate at the end of pegs (15A) which form the link to the wobble plate (17). The peg-ball joint is a sliding joint whereas the peg-plate joint is fixed. The wobble plate moves on a central ball (11) which can slide on the shaft. Variable stroke is obtained from a variable inclination of the wobble plate. ADVANTAGE - Simple precise adjustment of stroke.
Patent DE-4337225-A1 (DE)
Title: Active front bumper for vehicle - uses inertia forces to move bumper bar from passive to active position
Inventor: KOEPPEN RUDOLF
IPC: B60R19/40
Filed: 1993-10-30
Abstract: Active front bumper in which one or more telescopically mounted bumper frames comprising a bumper bar (21) and the support brackets (23) are moved from the passive position by inertia forces created as a result of braking. The bumper frames move against spring elements (28,34) to a deceleration-dependent capture position where they are held by locking pieces (27). The release of the locking effect is achieved by actuating the accelerator pedal (30) allowing the bumper assembly to return to the passive position. USE/ADVANTAGE - Active front bumper for vehicle contains damage at low speed collisions and minimises damage in higher speed crashes.
Patent DE-4338018-A1 (DE)
Title: Circuit arrangement for the transmission of signals
Inventor: LIEDTKE GUENTER
IPC: G01R31/02
Filed: 1993-11-08
Abstract: In known circuit arrangements a fault detection unit is provided between sensors and control units. However, the said fault detection unit does not indicate the magnitude and location of the fault. Therefore, the arrangement according to the invention provides for the control unit to have a circuit for forming output signals (Ua) which are below or above the normal working voltage range if there is a break in the connection lines so that the said break is detected by a connected diagnostic system or the fault evaluation circuit. Thus, it has become possible to determine whether breaks in connection lines have caused the fault.
Patent DE-4342360-A1 (DE)
Title: Stabilising system for vehicle
Inventor: JOHN THOMAS
IPC: B60G21/055
Filed: 1993-12-11
Abstract: The stabilising system is fitted to the vehicle suspension. The stabilisers (1a,b) are split and have torsional couplings (3v,3h) which cause a torque transmission depending on the angle of torsion. With large angles of torsion the stabiliser movement is displaced from the rear axle to the front axle. The first stabiliser (1a) is joined to the front axle via a rotary elastic coupling (3v) such that the torque transmission between the parts of the stabiliser is an increasing function of the rotary angle.

Patent DE-4411685-A1 (DE)
Title: Trocar with tapering rounded tip in which blade can be manually guided forwards
Inventor: WURSTER HELMUT DIPL ING
IPC: A61B17/34
Filed: 1994-04-05
Abstract: The trocar mandrel (1) has a manually or motor-driven cutting instrument (4) in the conically-pointed region. This instrument is movable w.r.t. the trocar sleeve in the length direction to an incision position in the distal direction and a rest, non-cutting position in the proximal direction. An operating mechanism sets the required position. The cutting instrument can only be operated when the pressure exerted on the trocar mandrel does not exceed a predetermined value. If this value is exceeded while the instrument is actually making an incision, it is automatically withdrawn. An electronic force sensor is built into the handle. This sensor generates a signal when the set pressure value is exceeded so that the operating mechanism for the cutting blade is electromagnetically shut off. The electromagnet used is bistable, i.e. moves according to the applied voltage and thus releases or blocks the operating mechanism.

Title: Electrical connection and a method for fitting it
Inventor: NIX LOTHAR HEINRICH WILLI
IPC: H01T13/04
Filed: 1994-07-11
Abstract: A spark plug wire has a connection (2) which has a cylindrical contact (4), a crimping sleeve which is fitted to conductors (72) of a cable (70), and a strain relief section (8) which is formed from arms (38) which produce an "F" crimped joint around the cable insulation (74). A crimping tool (50) for forming the crimped sleeve (8) of the strain relief section has a concave surface which is formed by a surface (66), as well as a lip region (68) extending away from it. When the crimping tool forms the insulating strain relief crimping sleeve, rounded edges (39) are formed on the front and rear edges of the crimping sleeve arms (38) so that, when a spark plug collar is pulled over the strain relief section (8) the material from which the collar is made does not tear. <IMAGE>

Title: Bulk grain hopper funnel
Inventor: HELLING KARL-HEINZ DIPL ING
IPC: F27D3/10
Filed: 1994-08-09
Abstract: A bulk grain (2) hopper (1) and outlet (3) release bulk solids esp. ultra-pure ore into a vacuum smelting furnace. The improvement is that a rotating collector funnel (4) is positioned below the outlet (3), whose rotational axis is inclined to the vertical, and which is laterally transposed from the outlet centre by a distance 'e'. The funnel outlet pipe (5) also serves as a hollow drive shaft for the funnel. The pipe (5) length is selected to meet the requirements of the process, and turns at a controlled speed. The lower plane of the rotating funnel inner face is co-incident with the outlet (3) base. The rotating funnel raises the bulk solids to a point of max. inclination (11) at which the solids slide into the outlet pipe (5) and are surrendered to the furnace (12).
