Abstract: Filter capsules for showers and sinks used in surgical settings, clean rooms and other contaminant-sensitive settings having modified outlets for improved splash control. Flat, concave, convex, asymmetric concave and asymmetric convex outlet inserts have pluralities of fluid bores with varying orientations to permit enhanced fluid flow control out of the filter capsules including divergent, convergent and mixed divergent/convergent fluid flows. An inlet with an axis offset at an angle to the longitudinal axis of the filter capsule body permits user control over the fluid flow strike point in a sink or shower stall via rotation of the capsule about the inlet connection point. A recessed outlet improves the prevention of contaminant dispersal by recessing the outlet away from contact points and potential contaminant sources. A filter cartridge top cap includes a downwardly extending extension with a concave bottom end to redirect fluids undesirably entering the filter capsule from the outlet away from the enclosed filter media and out the outlet.

Abstract: The present disclosure relates to a multifunctional film for a vacuum bag that may include a flexible barrier film that may include a textured surface. The multifunctional film may further include a release coating overlying the textured surface of the flexible barrier film. The multifunctional film may further have an oxygen (O2) permeability of not greater than about 1100 cc/(m2-day-atm) and a stability rating of not greater than about 90%, where the stability rating is defined as the maximum percent decrease in elongation at break as measured using ASTM D882 after being exposed to a temperature of 200° C. for 12 hours.

Abstract: Systems and methods include providing an annular seal for an assembly. The seal includes a metallic annular body comprising an inner sealing leg having a first sealing lip, a second sealing lip, and a valley disposed between the first sealing lip and the second sealing lip. The valley contains a plating reserve, such that the plating thickness in the valley is greater than the plating thickness on the first sealing lip and the second sealing lip.

Abstract: A bio-reactive container and filter assembly to improve flow rates and mass transfer without increased pressure. An inlet filter membrane secured to the container defines a container chamber in combination with the container. An inlet filter membrane element may also be secured to the container to provide structural support to the membrane. An outlet membrane secured to the container defines a container chamber in combination with the container. An outlet filter membrane element may also be secured to the container to provide structural support to the outlet membrane. Inlet and/or outlet filters and/or filter elements are constructed to significantly increase surface area available for fluid and/or gas ingress and/or egress. Single and double layer membranes with mixtures of hydrophobic and hydrophilic characteristics are used to maximize perfusion and gasification/degasification of bio-reactive containers.

Abstract: A composite includes a first layer of a first fluoropolymer; a second layer of at least one ply of a reinforcing fabric overlying the first layer; and a third layer of a second fluoropolymer overlying the second layer opposite to the first layer, wherein the first layer, the third layer, or combination thereof have an outer surface that is defect free; wherein the composite has a continuous length of at least about 3 meters. Embodiments of such composites can find applications, for example, as processing aids for an electronic device, a food, a polymer, insulating an electrical device, or heat sealing a polymer.
