Abstract: The present invention relates to methods and systems for culturing and purifying target substance(s), such as selected proteins, viruses, pathogenic bacteria, antibodies, antigens, clotting factors, glycoproteins, and hormones, from source liquids wherein the culturing and purification is effected in an integrated system including a bioreactor and at least one separation unit that functions under the control of a single operating system and provides for disposable components.

Abstract: The present invention relates to portable filtration units including filter components mated with retentate and permeate flow channels wherein particle containing solutions are introduced into the portable filtration units and contacted with the filter components for filtration thereby producing a retentate outflow and a permeate outflow for capture of desired end product.

Abstract: The invention relates to fibrous insulation products that exhibit improved flame resistance, relative to previously known products. The insulation product has a fibrous mineral matrix, into which is incorporated a phosphate-containing compound (e.g., an inorganic phosphate salt) and a refractory mineral filler (e.g., alumina or aluminum sulfate). The product exhibits flame resistance superior to the fibrous mineral matrix alone.

Abstract: The combination of a soft-goods item of folded fabric adapted to be displayed in a stack, and labeling for each item, has at least one band engaged around the item, spanning at least one of the narrow edge surfaces of the item. A self-supporting tag has a pair of slots spaced from each other and defining a labeling information carrying portion therebetween, and a pair of straps extending along each slot. The tag is threaded on the band which extends through both of the slots, and the tag is positioned at the edge surface so that the labeling information carrying portion is visible at the edge surface in a stack of the such items.

Abstract: An information displaying arrangement and method for items of soft-goods displaying in a stack, uses a band engaged around each item and spanning an edge of the item, and a tag having a pair of slots with the tag being threaded on the band which extends through the slots. The tag is at the edge of the item, so that the information printed on the tag is visible at the edge even with the item in a stack of such items.

Abstract: An intake and exhaust valve system (10) for an internal combustion engine having a combustion chamber (19) within a cylinder (13) closed at one end by a cylinder head (17). A cavity (25) is provided in the cylinder head opening onto the combustion chamber through a first port (27). The valve system (10) has first and second valves one of which is an intake valve (31) movable between open and closed conditions for controlling intake fluid flow into the combustion chamber (19) and the other of which is an exhaust valve (33) movable between open and closed conditions for controlling exhaust gas flow from the combustion chamber. The first valve (31) comprises a valve head (35) sealingly engagable with the first port (27) and a skirt structure (31).
