    摘要： A filter media product and method of making the same wherein the filter media is pleatable and has at least one support scrim comprised of a melt bonded non-woven material or a fuse bonded non-woven material bonded to a layer of expanded polytetrafluoroethylene. The filter media may have a single support scrim with one or more layers and optionally may have a support scrim on both an upstream and downstream surface where both or neither support scrim is multilayered. The filter media may have an efficiency greater than, equal to, or less than HEPA.

    摘要： A valve comprises a housing (1) having an inlet (4) and an outlet (5), and a pressure sensing port (8). A piston (6) slides in a part (3) of the housing (1) in response to a difference between a first fluid pressure at the pressure sensing port on the one side of the piston, and a second fluid pressure at the inlet and/or outlet on the other side of the piston (6). A valve member (7) carried by the piston is operable thereby to close the inlet (4) when said second fluid pressure is less than a value sufficiently greater than said first fluid pressure. The valve member (7) is movable with respect to the piston (6) to facilitate closing of the inlet (4), in response to a fluid flow from the housing (1) to the inlet (4), when the piston is not acting to close the inlet.

    摘要： An arrangement for producing a fibrous mat from a heated die source wherein the produced mat includes a first layered, preselected fiber portion of substantially straight fibers produced by directing such fibers directly to a collector source and a second layered preselected fiber portion of substantially curled fibers produced by diverting and exerting an external vortically creative curling force thereon before reaching the collector source.
