Patent DE-4109430-A1 (DE)
Inventor: PFALZGRAF BERNHARD DIPL ING
IPC: F02P5/15
Filed: 1991-03-22
Abstract: The invention discloses pinking control in a spark-ignition internal combustion engine with a short-time control in which, when pinking occurs, the value of an actual spark timing is retarded (SK) from a predetermined value of a characteristic field ( alpha V) in the direction "ignition retardation". In the absence of pinking, the actual spark timing is advanced to the predetermined value of the characteristic field (FK) in the direction "ignition advance". The invention provides a longtime adaptation whereby, when pinking (K) occurs, the characteristic field value ( alpha V) is reduced or modified by an adaptation value (LZW or LZK) of the pinking limit so that the short-time control is referred to a new predetermined spark timing value or another level ( alpha LZW or  alpha LZK). Adaptation values (LZW) are determined or changed only when the internal combustion engine has warmed up or has reached a temperature above a given threshold temperature (TS). At temperatures below the threshold temperature (TS), the adaptation values (LZW) are evaluated and reduced, preferably independently of temperature. The pinking control is thus adapted to a lower pinking tendency of the internal combustion engine after a cold start.

Patent DE-4227884-A1 (DE)
Title: Open-end spinner pneumatic fibre feed - has channel for auxiliary air stream to detach fibre fragments from the clothing of the sliver loosening roller
Inventor: GEBHARDT WOLFGANG
IPC: D01H4/32
Filed: 1992-08-22
Abstract: In the feed system for the fibres to an open-end spinner, an auxiliary air stream travels against the direction of sliver loosening roller rotation, from the immediate feed zone, to the entry of the fibre feed channel. The air stream is sufficiently powerful to detach fibre fragments moving around the loosening roller. The air stream width, to the fibre feed channel, matches the width of the loosening roller clothing. The fibres in the feed channel, detached from the opposite wall of the channel to the loosening roller, are passed by the auxiliary air stream into the channels against the direction of roller rotation over the opposite wall from which they are detached, and are moved into the channel by the auxiliary stream to the point where it meets the main carrier air stream. On entry into the loosening roller housing, the auxiliary air stream is moved radially against the delivery roller of the feed system. USE/ADVANTAGE - The system is a pneumatic feed of loose fibres produced by the loosening action of the roller on the sliver, for open-end spinning. The action prevents dust and lint for entering the fibre feed to the spinning section of the unit.
