Abstract: A tyre tread has a central and two side regions, each covering a third of the width. Three straight, wide circumferential grooves encircle the central region, defining two central bands. In the side regions there are cross grooves, conferring a block structure. In this original pattern, curved incisions with blind ends run from the bordering grooves (1) into terminations within the bands (3). Cross grooves (6) in two sections (6a, 6b) in the side regions have a V-shaped course and intersect with further grooves (7) running from the circumferential region.

Abstract: The blower 4 of a laundry drying apparatus comprising a stationary drying space 5 is formed by a high-performance blower which supplies the requisite volume of relatively drier air to dry the laundry via a temporarily increased flow of ambient air which is supplied with essentially no treatment. The hanging apparatus 6 for the laundry impinges on the laundry from at least two sides and fixates it in an essentially parallel arrangement with regard to the air stream. The result is a simple structure having low energy requirements for drying. <IMAGE>

Abstract: Building element (1) which is substantially parallelepipedal in design and has two visible surfaces (2), two supporting surfaces (3) and at least one abutting surface (4), and is provided with at least one horizontal channel (5) which opens out at the abutting surface, at least one vertical shaft (6) extending between the supporting surfaces being formed in the interior of the building element, which shaft is connected to the channel. The shaft can be laterally offset - seen in plan view - in relation to the channel. The abutting surfaces are provided either with central- or mirror-symmetrical profiles - relative to the centre of the building element seen in plan view. Formed on the supporting surfaces are groove (7) and tongue (8), which - viewed along the building element - can have further recesses or projecting portions. The manufacture takes place in individual working steps of a production line, two building elements in each case being clamped at a distance from each other in the direction of movement and conveyed together intermittently. The working steps are carried out both during standstill and during the movement. <IMAGE>

Abstract: The invention relates to a method and an apparatus for compressing gases, in particular air in a compressed-air conduit system. The gas drawn in is fed to the compressor via at least two different cooling sections of a freeze- drying system and cooled to below 0 degree Celsius in these cooling sections. The condensate, which is in the form of ice, is thawed and removed in one cooling section as the gas is being drawn in via the other cooling section. An area between the respective cooling section of the freeze- drying system to be thawed and the other cooling section or the compressor is closed off in a gas tight manner. <IMAGE>

Abstract: A hollow fibre separatory module comprises six separate hollow fibre bundles, four of which (12, 14, 18, 19) are shown, in a single pressure shell (10, 11). There are two fluid feeds (32, 86), two concentrate outlets (34, 88) and six separate permeate outlets, four of which (36, 40, 90,92) are shown. For reasons governed mainly by the lengths of the inidividual fibres in the bundles, the overall size of the individual bundles is limited. In the past separatory modules have consisted of a single bundle of fibres in its own individual pressure shell. Such modules have such a small output that they are largely only useful for experimental work. The multi-bundle module in accordance with the invention has much greater commercial usefulness.
