摘要:
An apparatus for purifying air, in particular for ventilation and air-conditioning systems, has an air filter (11), which is inserted in an air channel (10) or in a filter wall for collecting dust. A dust agglomerator (12) with a DC voltage field is connected directly upstream of the air filter (11). In conventional filters, the efficiency is increased to such an extent that the dust throughput can be approximately halved. In addition, the initial efficiency is only insignificantly reduced during the operating time.
摘要:
The filter, typically an air cleaning filter, has a frame element, preferably rectangular or square, retaining a plurality of adjacently located filter bags (4). The filter bags, themselves, are retained in the frame by bag-supporting ribs (6) which are folded from blanks (11, 11') in zig-zag fashion to define a central folded part 9, and two lateral folded portions (10, 10"10). To assemble the filter, adjacent filter bags are inserted and then clamped between the central portion and a lateral folded portion, and held together for example by adhesives, staples, or the like. The ends of the rib structures (6) define support legs (12, 12") which are secured to the frame element (1). The position of the ribs (6) determines the spacing of the filter bags (4). A spacing comb (14) formed with slits (16) determines the spacing between the opening of adjacent filter bags. The structure permits easy matching of filter bags to different dimensions of frame elements. Preferably, all materials used, frame element (1), filter bags (4) and ribs (6), are made of combustible material, for example paper and cardboard, or the like, so that the filter, including contents, can be incinerated as a unit.
摘要:
To provide a completely recyclable or incineratable filter bag holding frame, so that the holding frame together with the filter bags can be recycled as a unit, the holding frame is made entirely of recyclable and incineratable material in this manner: two essentially rectangular flat partial frames (1, 4) are made of groups of strips (1, 4), adhered together. Another group of strips (2), is placed on edge; the strips (2) have slits (8) therein extending from opposite edges, and spaced from the ends of the strips by distance slightly less than the width of the strips forming the partial frames. This provides an auxiliary frame (15), which is adhered to (1) of the partial frames. Core elements (5) of corrugated cardboard material are then placed against the assembly of the first partial frame (1) and the auxiliary frame (15), preferably adhered to both the partial end auxiliary frame. The outer surfaces of the core elements are then adhesively connected to on-edge strips (3) which, preferably, are also adhesively connected to the end edges (14) of the auxiliary frame (15) as well as to the first partial frame (1). The entire assembly is covered by a second partial frame (4), which is also adhered to the auxiliary frame (15) the outer strips (3) and the core elements (5). Preferably a hot, or hot-melted adhesive is used. One or both of the partial frames may be formed with inwardly extending projections (16) to be engaged by holding clips (18) of the filter bags (12).

Compounds and methods are provided for modulating in vitro and in vivo processes mediated by selectin binding. More specifically, selectin modulators and their use are described, wherein the selectin modulators that modulate (e.g., inhibit or enhance) a selectin-mediated function comprise particular glycomimetics alone or linked to a member of a class of compounds termed BASAs (Benzyl Amino Sulfonic Acids) or a member of a class of compounds termed BACAs (Benzyl Amino Carboxylic Acids).
