Abstract: A sealing element (5) for a filter element (2) in a housing body (1) of a filtration system, preferably in a cross-flow filtration system.

Abstract: A filter candle for precoat filtration has an end piece for connecting the filter candle to a separating wall of a precoat candle filter, a candle wall which together with a precoated precoat layer forms the active filter layer, and a terminating piece for separating an interior candle space from an unfiltrate space. An immersion tube is arranged in the interior candle space and reaches from outside the end piece, through the separating wall and the end piece, into a lower end portion of the interior candle space. At least one opening is provided in the immersion tube within the lower end portion, and a gap is formed between the immersion tube and the end piece.

Abstract: An apparatus for sorting particles of a bulk material moving on a transport ribbon (38) comprises an electro optical monitoring unit (101) above transport ribbon (38) for detecting the particles to be sorted out. Jet nozzles (45, 46) are controlled by a signal emitted by this electro optical monitoring unit (40), the jet nozzles being provided at the side opposite the bulk material of transport ribbon (38), which consists of an air permeable material. By means of the gas jet passing through transport ribbon (38), the particles to be sorted out are lifted off from the transport ribbon and are thrown into storage containers (47, 48).The bulk material is passed through a gap between rollers or grinding elements to provide flake-shaped particles which are then observed to provide first and second measurements which are subtracted from each other. A vibrating conveyor 87 with feeding channels 87.1 separate particles for disposition upon a ribbon 538 with the aid of a jet nozzle n.
