Patent DE-19907583-A1 (DE)
Inventor: GUETHLER HARALD
IPC: E03F5/10
Filed: 1999-02-22
Abstract: Drainage channel outflow system uses obstructions (8.1,8.2) moving in the flow direction to control, stop off or regulate the flow, one obstruction at least to rest at right angles to the channel (1) so all lie in a common plane (E). Between one obstruction and the channel wall (2) or between two facing obstructions (8.1,8.2) there is a vertical interval (12) and there is an overflow above the top edge of one of the obstructions. There is an additional outflow gap between obstruction and the channel whose section can be controlled by raising the obstruction accordingly. The obstructions come in prefered plate form and linked by joints. The load of the water flow bends the plates (8.1,8.2) in flow direction (X) and thus enlarges the flow interval (12). At reduced pressure and smaller water flow the plates re-set to reduce or even close off the interval (12).

IPC: B01D29/15
Filed: 2000-10-06
Abstract: A fluid filter element has a main filter media (30) and an outer wrap of filter media (82) stopping short of the end (94) of the main filter media to define a longitudinal gap (96). During fluid filtration, the amount of fluid flowing through the gap increases, to slow the increase in pressure drop across the filter element, to increase filter capacity and extend filter life. Contaminants release and drain from the end (90) of the outer wrap at the gap upon excessive loading of the outer wrap to further increase filter capacity and further extend filter life. In reusable cleanable filters, during backflushing cleaning, backflushed contaminants release and drain from the end of the outer wrap at the gap. <IMAGE>
