Patent DE-19709447-A1 (DE)
Title: Regulating method for fuel-proportioner with magnetic valve control for diesel engines
Inventor: SCHOENFELDER DIETBERT
IPC: F02D41/34
Filed: 1997-03-07
Abstract: Selection impulses (AS) for a magnetic valve are used to control the start and/or end of fuel proportioning, and increments (INKW) and a residual angle (RW) are determined beginning with a desired angular value (W). Starting with the residual angle, part increments (INKFW) are defined corresponding to the residual angle. The number of part increments is preset dependant upon the residual angle, an angle value (WINK), and a number (A), which denotes the number of part increments of a certain increment. The selection impulse is triggered, when the number of increments and part increments has been counted.

Patent DE-19803083-A1 (DE)
Title: Continuously operating backwash filter
Inventor: GEISBAUER HEINZ
IPC: B01D29/15
Filed: 1998-01-28
Abstract: Back washing is carried out through a set of channels isolated from the general filtration path. The filter element is a rigid cylinder through which the liquid flows radially inwards. Two axial backwash channels (14,11) are in close contact over the full length, and on both sides, of the cylinder wall. The channels are directly opposed so that there is a direct flow from the backwash fluid channel (14) to the waste channel (11).  The backwash medium, e.g. clean product or compressed air, is pumped into the channel via a pipe (13) and, passing through the filter, removes the filter cake and sends it to waste through the channel and drain (12). The channels are fixed whilst the filter drum rotates so that, since filtration and backwash are isolated systems, filtration can be a continuous process. The channel may contain a scraper.
