Title: Procedure for igniting lean air/fuel mixture thinned with air or exhaust gas
Inventor: LATSCH REINHARD DR ING
IPC: F02B23/10
Filed: 1997-04-10
Abstract: A procedure for igniting lean air/fuel mixtures thinned with air or exhaust gas has enrichment of the mixture with fuel in the region of the spark plug electrodes. In a process stage introduced to the spark ignition, additional fuel is transported and sprayed on the surface of a small trough in the piston and its surrounding on the piston base and/or in the form of enriched fuel. After at least partial evaporation of the fuel still deposited on the walls and further mixing with the existing enriched mixture, after immersion of a spark ignition device with electrode into the piston trough, the additional fuel is ignited.

Title: Testing and measurement of over-head conductor or other for component effected by friction
IPC: G01B21/12
Filed: 1997-04-17
Abstract: The method involves producing a relative movement by using a measuring device having guide rollers. A deformation of inserted slide and/or guide bearings, etc., is prevented by minimizing or preventing a current flow through suitable insulators. A server is mounted on a parallel-vertical positioning device. The bearing of the server is preferably pressed against the conductor by spring forces. Bearings or rollers to produce the relative movement are mounted to a path-guide of the server or directly to the server.
Patent DE-19719555-A1 (DE)
Inventor: BROCKHOFF ALEXANDER
IPC: B04C3/06
Filed: 1997-05-09
Abstract: Gaseous blood is conveyed as a cyclone eddy current by a rotary cyclone whirl chamber (26) which has a cyclone inlet (40) axially spaced apart from the cyclone outlet (28). A gas outlet (60) discharges the gas phase from the blood phase. The cyclone inlet is formed by at least one threaded circularly leading blood-inlet duct (36) using which the gaseous blood enters at a tangent into the cyclone whirl chamber. The blood in the blood inlet duct is constricted at least along part of its length to a smaller flow cross-section, thereby accelerating its flow speed. The gas phase is conducted out of the radially inner centre of the cyclone whirl current at a part upstream from the blood inlet duct in a direction between the axial forward and tangential movements of the cyclone whirl current.

Title: Method of synchronising navigation measurement data with synthetic aperture radar data
Inventor: BUCKREUS STEFAN DR
IPC: G01S13/90
Filed: 1997-07-15
Abstract: The method involves determining an offset signal for an aircraft in the direction of view of the radar antenna from synthetic aperture radar data using the reflectivity offset method. The offset signal is cross-correlated with a signal derived from the navigation measurement data. The position of the cross-correlation maximum indicates the function of the time offset between the radar and navigation data. The radar data are delayed by this time before the movement errors are compensated.
Patent DE-19731496-A1 (DE)
Inventor: STRACK HELMUT DR
IPC: H01L29/423

Title: Road vehicle door closure
Inventor: KOEPPEN WINFRIED DR
IPC: E05B77/06
Filed: 1997-09-03
Abstract: The pivot lever for unlocking a door locking mechanism is pivotable in relation to the housing around a pivot axis parallel to the direction of travel. A blocking device prevents an undesired opening of the door by a lateral acceleration, as the result of which the forces act on the pivot lever and/or the manoeuvring device, which may be adequate to unlock the door locking mechanism. The blocking mechanism incorporates a movably located stop component, which is moved by the lateral acceleration in relation to the pivot lever, blocking its pivot path. The stop component (6) is so located on the pivot lever (2) that under the effect of the forces there is a relative movement between the pivot lever (2) and the stop component (6). As a result of this, the stop component (6) works in conjunction with a stop (14) fixed to the housing, in order to block the pivot path of the pivot lever (2).
