Abstract: The invention relates to a connector head (12) comprising an interior space (40), a tank connector (13) which is in fluid communication with the interior space (40) and which can be fluidly connected to a valve apparatus (10) mounted on the tank (9) for filling or emptying the tank (9), a product port (14) in fluid communication with the interior space (40) and a discharge port (33) in fluid communication with the interior space (40). To allow a tank to be filled and emptied under improved hygienic conditions, it is proposed that the connector head (12) comprises a first valve (29), with which first valve (29) the product port (14) can be shut off from the interior space (40), a second valve (34), with which second valve (34) the discharge port (33) can be shut off from the interior space (40), and a cleaning device (38) adapted and arranged to clean the interior space (40) and the tank connector (13). The invention also relates to a valve block.

Abstract: A piece of furniture is equipped with a table top (3) which can be adjusted both in height as well as in its angle of tilt and which is suspended in a stand which consists of two hollow side pieces (1) and a hollow connecting bracket (2). Both the rear as well as the front adjusting mechanisms consist of standardized parts (29, 33, 35, 36, 39, 40) and the same parts can be used in most cases for both mechanisms. This ensures an economical manufacturing process and simplifies storage-keeping. The adjusting mechanisms can be loosely assembled for the most part without any tools, a fact that makes it possible even for unskilled workers to assemble and disassemble the device.

Abstract: This piece of furniture is designed for setup at the work place in a modular design concept and has an adjustable tabletop. At the rear edge of the tabletop (1) there is at least one bolt (27) with a projecting end which passes through a vertical slit (29) in a hollow beam (3). In the hollow space of this beam, there is at least one vertical adjusting spindle (32) which has a follower nut (31). This follower nut is connected to the bolt (27) in such a way that when the spindle is turned, the rear part is raised or lowered. The adjusting mechanism is easy to operate and permits infinite adjustment of the rear side of the tabletop. It takes up very little space, so that electrical lines and other facilities can be housed easily in the hollow space of the beam.

Abstract: The office furniture item is provided with at least two lateral parts (1) interconnected by a connective support (21). The lateral parts (1) and the connective support (21) are provided with a continuous cavity. Each lateral part (1) comprises a core element (2) with a supporting column (6) from which a leg part (5) and a supporting arm (7) protrude. The core element (2) is provided with recesses (9,10,11) which are at least partly sealed by the cover means (3,4,16). The office furniture item is appropriate for the working station design in modular design. Signal cables and electrical conduits can be inserted at any time without any problem. They are invisible from the outside.

Abstract: Two lateral parts (1) interconnected by an upper support (21) are provided in an office furniture unit, with an adjustable table top (22) being arranged between said lateral parts. The adjustment of the table top in the tilt and vertically is accomplished by lateral and posterior pin engagements (35 and/or 32). A bolt (28) which is positioned for reciprocal movement is arranged in the posterior edge (26) of the table top (22). The head (54) of the bolt (28) grips behind a vertical slot (38) of the support (21). Upon disengagement of the table top for its adjustment, it remains connected to the support via the bolt so that it cannot drop out.
