Patent DE-19535094-A1 (DE)
Title: Misfiring detection of one or more continually misfiring cylinders of IC engine
Inventor: LOHMANN ANDREA DIPL ING
IPC: G01M15/11
Filed: 1995-09-21
Abstract: The method is based on a first input characteristic signal representing the irregularities in the speed of rotation of the IC engine of the first order and comparing it with a threshold value and a second greater threshold value. Further input characteristic signals representing irregularities of other orders, the number depending on the number of cylinders, are compared with individual threshold values associated with the individual orders. If the first threshold is exceeded provisionally continual misfiring of one cylinder is identified whilst if one of the further thresholds is exceeded or if the first input signal exceeds the second threshold value, a misfiring signal indicating continual misfiring of several cylinders is activated. If the misfiring signal is not activated the provisional identification signal is switched externally.

Patent DE-19536568-A1 (DE)
Title: Method for manufacture of two colour decorative sand lime masonry blocks
Inventor: HENKE AUGUST
IPC: B28B13/02
Filed: 1995-10-02
Abstract: The method involves the delivery of two differently coloured sand lime mixtures at the same time and one after the other into a funnel-shaped hopper. The material is deposited on to one side of the hopper and forms differing layers parallel to it at its natural angle of repose. The opposite side of the hopper is vertical.  The material is released from the base of the hopper into an open bottomed filling carrier in slices controlled by a horizontally sliding discharge plate. The car moves along a flat surface (20) until it can discharge where the material undergoes a further mixing and change of appearance as it drops into a series of moulds (21).

Patent DE-19541927-A1 (DE)
Inventor: LUTZ PETER DIPL ING
IPC: F02B3/06
Filed: 1995-11-10
Abstract: A method of controlling a fuel-admetering system, especially for a diesel engine, comprises ascertaining the difference (SBD) between a target value (SBS) for fuel conveying start and the actual value (SBI) for conveying start, and, in dependence on this difference (SBD), determining a setting magnitude (P) for action on a setting member. A time magnitude for the target value of conveying start is ascertainable with reference to a reference instant. A correcting magnitude, which takes into consideration the deviation between angular magnitudes referred to the engine camshaft and angular magnitudes referred to the engine crankshaft, is determined starting from the difference between the instant at which the actual start of conveying is recognised and the time magnitude for the target value of conveying start.

Patent DE-19643189-A1 (DE)
Title: Motor vehicle roof with vent
Inventor: HILLERBRAND FLORIAN
IPC: B60J7/16
Filed: 1996-10-18
Abstract: The vent (16) flow channel (18) extends along the roof and has inlet (72) and outlet (74) openings and varies in sectional area lengthways. Thus the venting opening (82) lies in a channel (19) section relatively narrower than the inlet and outlet openings (72,74). The channel tapers continuously from the inlet and then steadily expands to the outlet so the narrowest part of the channel (19) lies halfway along it (76) in the rear part of the channel.  The vent (16) is extended by a toggle (24,26) and drive bar (68) from its closed position flush (70) with the main roof (10) and the channel (18) thus below the roof surface into one or more raised positions to bring the channel (18) above the roof surface (10) so as to admit air as a function of vehicle speed. When closed, the vent (16) seals the roof shut. The top ends (28,32) of the toggle levers (24,26) are hinged to the vent and again hinged (34,36) halfway to the roof (10) and to the bar (68) at their bottom ends (64,66).
