Patent DE-19757402-A1 (DE)
Inventor: BOETTCHER MARTIN DIPL ING
IPC: H02B11/167
Filed: 1997-12-16
Abstract: The invention relates to a circuit breaker system, especially an air-insulated medium voltage switchgear, with the functional features "connect", "disconnect" and "earth".

Patent DE-19757986-A1 (DE)
Inventor: JESSBERGER THOMAS
IPC: F02M25/07
Filed: 1997-12-24
Abstract: The invention relates to a suction device (11) for an internal combustion engine (12) which device is fitted with separate air intake means (14) for each cylinder, whereby in addition to the intake air exhaust gases can be fed to the suction device via exhaust-gas supply means provided separately for each cylinder. Because exhaust gas is supplied to each cylinder separately the quantity of exhaust gas supplied can be measured precisely and in particular be the same for each cylinder. In a preferred version of the invention the exhaust-gas supply means are situated in a connecting flange (15), which together with the air intake means (14) is mounted on the housing (13) of the engine (12) and has continuous air ducts (20). The exhaust-gas supply means are configured inside the connecting flange (15) as openings leading from a distribution chamber (23) collecting exhaust gas to the air ducts (20) or as exhaust-gas ducts (21) existing separately from the air ducts. The intake flange (15) which is heated by the exhaust gases is cooled sufficiently by being connected to the surface of the engine housing (13) and by the fact that intake air circulates through it.

Patent DE-19806077-A1 (DE)
Inventor: BARTSCH THOMAS
IPC: B60T8/40
Filed: 1998-02-14
Abstract: The invention relates to a rotor mounting for a motor pump aggregate (1) comprised of two mounting positions for accommodating radial loads and a third mounting position for accommodating axial loads on the shaft of the rotor (2) of the motor pump aggregate (1). Both radial bearings are constructed as plain bearings or as antifriction bearings, preferably from a needle bearing. The axial mounting (4, 5) is configured within a determined degree of freedom by the magnetic pull of the electric motor or is configured without a degree of freedom by a playfree mounting of the ends of the rotor shaft. Emergency running bearings with floating mounting take over the axial component of the mounting for peak loads in an axial direction. Said emergency running bearings are thus constructed out of stop elements. The stop elements are either arranged on the shaft of the rotor (2) or in the pump housing (10) of the motor pump aggregate (1) and are constructed such that they are resistant to wear.

Patent DE-19825374-A1 (DE)
Inventor: GERHARDT JUERGEN
IPC: G01P3/48
Filed: 1998-06-06
Abstract: Disclosed is a device for determining rotational speed. Rotational speed is determined from the torque measured on the crankshaft of an internal combustion engine. Since torque fluctuates according to the gas force or combustions dependent upon the angle of rotation, rotational speed (n) is calculated according to periods of time (T), whereby the number of cylinders (Z) is taken into account. Evaluation and calculation of signals is normally carried out in the control unit of the internal combustion engine.

Title: Side impact simulation system simulating intrusions and accelerations of vehicle side structures and whole vehicle
Inventor: HILLENBRAND KLAUS
IPC: G01M17/007
Filed: 1998-11-27
Abstract: The system has a door (9) and a main (8) cradle, which are rigidly connected through a bumper system. The parts of a subdivided vehicle wall structure (4) are linked at points that correspond to bends or folds of a vehicle produced by a real impact trial. The main cradle is coupled so that a lateral displacement of the total vehicle is replicated, and the wall deformation is produced by the relative movement between the door and main cradles. The door cradle carries the subdivided wall structure on its impact side. The door cradle contains or carries the parts of the vehicle side structure parts or side doors. The parts of the wall structure are jointed to each other by joints (6,6') at points, which correspond to bends or folds of vehicle side structures produced in a previous real side impact trial or stemming from a computer-assisted structural computation, so that with the door cradle, the deformation and relative accelerations of the vehicle side structural parts with a side impact can be assumed to be realistic. The door cradle in a simulated collision direction can be acted on with a pulse of predetermined direction.  The main cradle is rigidly connected to a structural part (1) formed after the floor plate. The  main cradle carries the vehicle seats (3) and is coupled to the door cradle by a bumper system (10), so that after an impact of the door cradle, it is carried in the impact direction of the door cradle by the coupling over the bumper system, so that a lateral displacement of the total vehicle is replicated and the simulation of the deformation and relative movement of the wall structure is produced by the relative movement between the door and main cradles.
