Title: Rail-guided, longitudinally displaceable vehicle seat
Inventor: JOVANOVIC NENAD
IPC: B60N2/06
Filed: 1987-07-29
Abstract: A rail-guided, longitudinally displaceable vehicle seat is shown, in which an energy-storing element is provided to assist the sliding movement in one direction. In order also to be able easily to displace the vehicle seat in the opposite direction, the direction of action of that energy-storing element can be reversed. To this end, this energy-storing element (helical spring) is for example guided via a lever arm which can be positioned in various different ways. Alternatively, an angled, rotatably mounted spring bar is proposed which after being rotated by 180@ strives to displace the seat either forwards or backwards because of its preloading. In this connection, the positioning of the lever arm or the rotation of the spring bar takes place by swivelling the backrest using Bowden cables as transmission elements.
Patent DE-3728649-A1 (DE)
Inventor: LUDWIG ALBERT
IPC: B44B5/02
Filed: 1987-08-27
Abstract: An installation for sorting out reject slugs out of the slug channel of an automatic coining machine with a slug control mechanism, whereby the reduction of the reaction time for the rejection of slugs to be sorted out permits a considerable increase of the number of coining strokes of the automatic coining machine, without the need for a further additional intermediate storage of slugs. The reject channel for rejected slugs is thereby kept closed by shaped members in the manner of shutters and is opened up in case of need whereby also the desired dimensions for the slugs are determined by the shaped members. Such a slug control mechanism is needed in the slug channel of an automatic coining machine in order to separate good slugs from reject slugs.

Patent DE-3904364-A1 (DE)
Title: Separating off individual components from liquid mixtures by layer formation in accordance with density
Inventor: STARK HELMUT
IPC: B01D17/02
Filed: 1989-02-14
Abstract: According to the invention, separation of the individual components of liquid mixtures is carried out by allowing the mixtures to stand in vessels as a result of layer formation in accordance with their density. The vessels optimally have a small base in relationship to their height. The outlet should be funnel-shaped in order to achieve gentle slow discharge of the liquid without turbulence. In order to establish when a new layer arrives at the outlet, the liquid runs through a vessel in which there is an areometer (hydrometer) from which it is possible to read off when the density changes. The advantage of the method is that individual components are more readily utilisable than mixtures as arise, for example, in exhaust gas scrubbers.
