Abstract: A lifting apparatus has two frame assemblies positioned one above the other, so as to be mutually parallel, with respect to a vertical direction, the lower frame assembly suspended on the upper frame assembly using lifting traction means, such that the lower frame assembly can be drawn up towards the upper frame assembly by winding the lifting traction means, and the lower frame assembly can be lowered relative to the upper frame assembly by unwinding the lifting traction means. Oblique traction means extend between the frame assemblies that can be wound and unwound using a tensioning device, two of which mutually intersect such that the lower frame assembly is stabilized, relative to the upper frame assembly, in at least one deflection direction transverse to the vertical direction. The tensioning device may comprise four tensioning drives. According to an alternative exemplary embodiment, the tensioning device may comprise only two tensioning drives.

Abstract: A scissor-lift platform comprises a scissor mechanism (1) and scissor elements (3) that are connected to form scissor element pairs by central bearings (2). At least one scissor element (3) of a scissor element pair has a bearing receiving element (4) that is removably connected to the scissor element (3) in order to receive the central bearing (2).

Abstract: A scissor lift table (1) has a first base element (2) and a second base element (3) and a scissor (4). The scissor (4) has a first scissor part (6) and a second scissor part (7), wherein the first scissor part (6) and the second scissor part (7) are pivotable relative to one another about a scissor axis (5). The first base element (2) and the second base element (3) are connected by the scissor (4) such that a pivoting of the scissor parts (6, 7) relative to one another about the scissor axis (5) causes a change in the distance between the first base element (2) and the second base element (3), wherein the first scissor part (6) is pivotably borne on the first base element (2) using a fixed bearing (10) and the second scissor part (7) is displaceably and pivotably borne on the first base element (2) using a floating bearing (11).

Abstract: A scissors lift comprises an upper frame module (1) and a lower frame module (2), a scissor mechanism (3) and a drive unit (4). The upper frame module (1) and the lower frame module (2) are connected by the scissor mechanism (3) in such a way that a lifting movement, by which the spacing between the upper frame module (1) and lower frame module (2) changes, is rendered possible. The scissors lift, particularly the upper frame module (1) and/or the lower frame module (2), have a central portion (5) to which extension 6 and/or 7 that are pre-produced in fixed sizes and are fitted together in the manner of a modular construction system to make a scissors lifting lift of desired size.

Abstract: A scissor-type lifting table has a carrying device (10) and a base device (11). A scissor mechanism comprising first and second scissor-blade arrangements are arranged between the carrying device (10) and the base device (11). The carrying device (10) can be moved away from the base device (11) by means of a lifting truck (3) which can be moved via at least one traction mechanism (4), by winding up of the traction mechanism (4), and can be raised up in order to open the scissor mechanism and can be lowered in order to close the scissor mechanism by unwinding the traction mechanism (4). At least one lifting cam (8) is provided which is configured to regulate the lifting capacity and along which the lifting truck (3) runs during the raising or lowering of the carrying device (10).

Abstract: The invention relates to a simple and inexpensive method for simultaneous isolation of cells and/or bioparticles from complex fluids that differ in one or more surface properties (e.g. cell sub-populations). For that purpose, the surface of a solid carrier is modified in a manner to be provided with different capture molecules, which allows in an additional step a specifically “neutralizing” of individual target particles. Different target particles with both identical and different recognition structures are to be gradually detached from the capture particles and isolated/separated. Areas of application of the invention are biotechnology (including biological and medical research), diagnosis and treatment of diseases.

Abstract: Mixing, physical and/or chemical reactions and separation are basic method steps in biological research and diagnosis. In research in particular, there is a need for problem-specific laboratory systems, but these are not commercially available because of small batch sizes and because of the specific problem involved. In the absence of these systems, existing vessels, filters, centrifuges, etc., have to be improvised in order to solve the problem. The aim of the invention is to make available a system of functional units that can in each case be plugged together depending on the methodological problem.

Abstract: A felly tube holds, by shrinkage, a sound-absorbing body in the felly of a wheel adapted to carry a pneumatic tire. The felly tube is woven with a central region which is more tightly woven than a pair of selvage regions which have greater-length weft floats. The shrinkable threads are incorporated as a warp of the selvage regions.
