Abstract: A chair guiding device including: a rail guide that extends between a starting and an end position of a chair receptacle; a carriage, which carries the chair receptacle and is displaceably mounted on the rail guide; and a housing, comprising a base body and a cover on which an elongated hole is incorporated, in which the chair receptacle is arranged so as to be movable back and forth. The rail guide is arranged pivotably about a rotational axis. The rail guide is arranged on a tilting plate, which is pivotably mounted on a revolute joint comprising the rotational axis. The tilting plate, together with the rail guide, is surrounded at least partially by the housing; and a means is provided that can pivot the tilting plate by an angle (?) relative to the horizontal plane EB.

Abstract: A seat guide device has at least one linear guide system and a seat base supported in a movable fashion on the carriage of said system against the force of a spring. The device further comprises: (a) damping element coupled to at least one of the carriage and the spring, and (b) a block and tackle which includes: (1) one fixed end which is attached to a stationary attachment point; (2) one loose end which is connected to the carriage; and (3) one first loose pulley which is connected to a stationary attachment point via the spring.

Abstract: A filter-replacement cassette for an extruder. A housing (1) has at least one bore. The bores (2 & 3) extend above and below and at a right angle to the horizontally flowing plastic. A cartridge (4 or 5) that accommodates a replaceable filter (5) slides back and forth inside each bore. The object is to facilitate start-up operation. The cartridge accordingly has at least one tap (7, bore 15, or bore 45) permanently integrated into it in addition to the replaceable filter. The housing accommodates either a cartridge or a start-up outlet bore (16, 36, or 47). While the cartridge is in a prescribed position, the start-up outlet bore can communicate with the cartridge's tap and with an intake channel (13 or 31) for the extrudate.
