Abstract: The tray column (1) has downcomers (3) for transporting a liquid between adjacent trays (2). The liquid transport takes place in each downcomer through a plurality of discharge apertures (32) onto a loaded tray. Liquid flows out of the discharge apertures in the form of jets (60) that blend into a regionally divergent flow field (6) on striking the loaded tray. The flow field has transverse components of the flow speed with respect to a longitudinal main flow direction (61). Guide elements (4) are arranged beneath the discharge apertures and at a spacing from the loaded tray which each guide the impulse of liquid corresponding to the divergent flow field. The guide elements contribute to forming the transverse speed components such that the longitudinal component of the flow speed has a largely constant profile in each plane perpendicular to the main flow direction.

Abstract: A ball-and-socket joint, preferably for chassis suspensions and/or steering mechanisms of motor vehicles, is presented, which has a ball pivot pin (1), which is accommodated rotatably and tiltably in a joint housing (8) with one of its free ends with a spherical joint area (3). The other free end of the ball pivot pin (1) is fixed to a body part. The ball-and-socket joint has a stop device for limiting the tilting movement of the ball pivot pin (1) in the joint housing (8), which comprises a stop element, which is arranged in the bottom area (11) of the joint housing (8) rotationally symmetrically to the longitudinal axis of the sphere and cooperates with the end-side joint area (6) of the ball pivot pin (1).

Abstract: The liquid distributor (1) for columns (6) has a main passage (2), a plurality of secondary passages (3) and an outflow system (5) of the main passage. The liquid (4) to be distributed can be fed into the secondary passages in accordance with a pre-set ratio by this outflow system. The outflow system (5) comprises apertures (20) in the side walls of the main passage and—associated with the secondary passages—guide elements (50) for the liquid (41) exiting through the apertures. The guide elements are designed with respect to a liquid guidance such that the liquid (42) can be led into the associated secondary passage.

Abstract: The invention relates to protein conjugates, methods, vectors, proteins and DNA for producing them, their use, and medicaments and vaccines containing a certain quantity of said protein conjugates. According to the invention, supramolecular particles are produced that represent one or more different, randomly selectable structural units in a large number on the surface of an individual, approximately spherical protein molecule. Icosahedral lumazine synthases are used as carrier proteins for peptides or proteins. A DNA fragment that encodes a peptide molecule is fused with a DNA fragment that encodes an icosahedral lumazine synthase by molecular-biological methods. Said DNA fragment is inserted into a cloning vector and transformed with an appropriate host strain. A polypeptide is expressed by gene expression. If certain peptide structures are used as the fusion partners, a post-translational change of said structures can be observed in the host strain.

Abstract: A counterflow column that includes a liquid distributor including a plurality of tubular or trough-like distributor members. The distributor members are arranged in a column above a packing such that a plurality of partial flows develop in an upwardly flowing gas at the level of the distributor members. Stagnation zones are present between the packing and the distributor members. Through screen-off structure, not required per se for a liquid output, the stagnation zones and/or the flow of a liquid to be distributed are influenced such that a liquid, after emerging from the distributor members and prior to entry into the packing, traverses in free fall through the stagnation zones, and where appropriate also further regions, in which the gas flow is largely free of horizontal velocity components. The gas flow may also be influenced by a suitable shaping of the distributor members.

Abstract: The invention relates to an anti-theft device, especially for skis, comprised of a cable (3), a cable drum (2) specially connected to an end of the cable (11) in a fixed manner and a locking device (4) which contains at least one clamping element (12, 13) is provided for fixing the cable (3) which is inserted into the locking device (4). In addition, the clamping element interacts with the lock (8) in such a way that the clamping element (12, 13) releases the cable (3) when the lock (8) is opened and prevents the cable from being pulled out in a direction contrary to the direction of insertion when the lock is closed (8). The clamping (12, 13) is mounted such that it can rotate and be moved in the locking device (4). The clamping element interacts with the lock (8) via a pivoted lever (22, 23).

Abstract: The counterflow column (1) contains a liquid distributor (2) having a plurality of tubular or trough-like distributor members (21). These distributor members are arranged in a column above a packing (3) in such a manner that a plurality of partial flows (40) develop in an upwardly flowing gas (4) at the level of the distributor members. Stagnation zones (45) are present between the packing and the distributor members. Through additional means (24), which are not required per se for a liquid output, the stagnation zones and/or the flow of a liquid (5) to be distributed are influenced in such a manner that a liquid (50), after emerging from the distributor members and prior to entry into the packing, traverses in free fall the stagnation zones and where appropriate also further regions in which the gas flow is largely free of horizontal velocity components. The gas flow can also be influenced by means of a suitable shaping of the distributor members.

Abstract: A liquid distributor for packing columns. The liquid distributor includes at least one tubular or trough-like distributor member including outlet openings for an output of liquid in the form of jets. Screens are arranged ahead of the outlet openings onto which the incident liquid jets are deformed to liquid films flowing off. The outlet openings screen the outlet openings against an upwardly flowing gas flow. In the event of a maximum output of liquid, the liquid jets are incident onto the screens at angles that are less than 60°, and even as much as less than 10°.

Abstract: A ball-and-socket joint for motor vehicles is described which includes a housing (3), a bearing shell (4), which is inserted into the housing and accommodates a joint ball (1.3) of a ball pivot (1) exiting from the housing on at least one side movably in all directions. The ball pivot is provided with a connection contour (1.4) on the side opposite the joint ball. The ball-and-socket joint also includes a sealing element (2) in the form of bellows, which is sealingly in contact with the housing, on the one hand, and with a shoulder (1.5) of the ball pivot, on the other hand. A circular ring collar (1.1) provided with an undercut contour is made in one piece with the ball pivot (1). The sealing element (2) is inserted with its area (2.1) that is sealingly in contact with the ball pivot (1) into the annular space (1.2) formed by the undercut under elastic pretension.

Abstract: A manual drive for producing rotary movement in both clockwise and counterclockwise directions includes a drive lever which has a neutral position from which it can move into a first or second rotary direction. Attached to the drive lever are a pair of detent elements, one controlling clockwise rotation of the drive wheel and the other controlling counter-clockwise rotation. The detent elements have teething elements on a free end for engagement with a drive wheel which has counter teething about its circumference. The detent elements engage the drive wheel in the neutral position. The detent elements slide in a slide guide which lifts one of the detent elements out of engagement with the drive wheel when the drive lever moves in the opposite rotary direction. Springs located on either side of the slide guide lift the detent element on the drive side out of engagement with the drive wheel as the drive lever returns to the neutral position.

The seat includes a height adjusting mechanism for adjusting the height of the seat frame. The height adjusting mechanism includes a drive shaft connected to an end of the adjusting lever, wherein rotation of the shaft effects vertical movement of the adjusting lever and height adjustment of the seat frame.
