Title: Efficient spark ignition system for IC engine
Inventor: SIMON HEINRICH DIPL ING
IPC: F02B23/10
Filed: 1996-11-08
Abstract: A spark ignition system for an IC engine (1) having an otherwise conventional construction is shown applied to a fuel-injected cylinder block (30) in which the injector assembly (100) is provided with the ionising electrodes (102) supplied from the HV source (70). The block (30) contains a number of permanent magnets or alternatively EM coils (200) concentric with each combustion chamber (10) which produce a concentrated axial field (210) aligned with the cylinder axis (220). The changed fuel vapour (80) is constrained in a spiral path (225) or is magnetically reflected towards its origin thus greatly assisting the efficient ignition/combustion of even lean mixtures by a fixed sparkplug (62) in preventing fuel dispersal throughout the chamber (10).
Patent DE-19649115-A1 (DE)
Title: Saw blade etc side guide roller
Inventor: HEHN WERNER DIPL ING
IPC: F16H55/44
Filed: 1996-11-27
Abstract: The roller or its slide bearing (4) has a guide ring (1,2) fixed to the bearing ring (3) so the ring (1)(2) part (8,9) coaxial to the bearing ring bears on the ring (3) surface casing. The ring (1) sectors (8,9) are adjoined by an integrated edge piece (10,11) directed radially outwards. Preferably there are two rings (1,2) to guide the interposed saw blade or cable etc at the side, the edge pieces (1,2) at an angle to the roller rotation axis so as to define a wedge-shaped annular groove (12). The inside edge pieces integrated into the sectors (8,9) overlap the outer ring (3) in the radial direction and bear against one endface of the bearing ring (3) and in so doing determine the guide breadth of the roller. The rings (1,2) are mutually mirror-symmetrically arranged on the ring (3) and similarly orientated to the bearing ring (3). In a variant, the roller guide ring is folded at both ends into axi-parallel folds confined by one ring sector and the fold legs, and in this case the side pieces are integrated where they adjoin the legs of the folder.

Inventor: SPLETT ARMIN DR ING
IPC: H03L7/093
Filed: 1996-12-20
Abstract: The invention concerns a method of recovering timing from a digital signal (In) using a phase-locked loop. The phase deviation between the digital signal (In) and an output signal (Out) from an oscillator (3) is determined, and a loop regulator (5) controls the oscillator (3) as a function of the phase deviation determined, in order to minimize the latter. The method is characterized by the detection of phase deviations caused by stuffing processes in the digital signal (In) and by the minimizing of the phase deviation portion caused by stuffing processes, which deviation is to be fed to the loop regulator (5).
