Abstract

A multi-element filtration vessel included spaced beams for supporting and/or aligning filtration elements from below. The filtration elements have bottom ends adapted to rest upon adjacent support beams and also to extend between them to form a cavity that can capture feed fluid and an aeration gas and conduct it into the filtration element. In another aspect, a multi-element filtration vessel has removable aerators mounted on a projection on the wall of the filtration vessel.

Abstract

The present invention provides a batch or semi-batch method and system for treating a feed solution. A hyperfiltration system is suitable to switch between two modes: a recirculation step wherein the retentate stream from hyperfiltration membrane elements is recycled and a flush step that displaces a retentate stream to an outlet. The hyperfiltration system includes an array design optimized to increase the flush efficiency during the flush step by equalizing the hydraulic residence time of different flow paths through a pressure vessel array. The substantially equal hydraulic residence times result in more uniform displacement of solute from the system, lower over-all flush volumes to displace accumulated solutes, and minimal variation in the age distribution of solute that accumulates within the system.

Abstract

A two-part polyurethane adhesive exhibits excellent adhesion to low surface energy substrates such as polypropylene. The adhesive consists of a polyol component and a polyisocyanate component that are combined and cured to form the adhesive bond. The polyol component is characterized in containing a monoalcohol that has a molecular weight of 100 to 2000. The presence of the monoalcohol promotes strong bonding and a cohesive failure mode that is preferred in vehicular applications.

Abstract

A multi-element filtration vessel contains multiple filtration elements. The elements have cylindrical housings and an annular header. At least a portion of the annular header surrounds the cylindrical housings at one end. The annular header has a periodically varying cross-sectional width and thickness such that the annular header has alternating thinner and thicker regions. The elements are packed with thinner sections of the header aligned. This allows for close packing of the elements without unduly compromising the mechanical strength of the headers.

Abstract

The present invention provides a semi-batch method and a hyperfiltration system for treating a raw water. The hyperfiltration system is suitable to switch between two modes: a recirculation mode wherein the concentrate stream from hyperfiltration elements is recycled and a flush mode that sends the concentrate stream to discharge. The hyperfiltration system includes an energy recovery device suitable to recover energy from the concentrate stream during the flush mode. Liquid flows through the energy recovery device during at least a portion of said recirculation mode. Preferably the energy recovery device is an isobaric energy recovery device or a pressure exchanger.

SELF-ADHERED SYSTEM FOR SEALING BETWEEN ADJACENT BUILDING STRUCTURAL ELEMENTS

Abstract

Gaps between adjacent members in a building construction are sealed by applying a self-adhering barrier sheet to the adjacent members to span the gap. The self-adhering barrier sheet includes a flexible sheet of a barrier material. The flexible sheet has opposing edges, of which at least one is tapered. A pressure sensitive adhesive is applied to at least a portion of at least one major surface of the flexible sheet. The edges of the self-adhering barrier sheet are adhered to the adjacent structural elements by means of the pressure sensitive adhesive. The pressure sensitive adhesive has a thickness equal to or less than the maximum thickness of the flexible sheet. Where two self adhering barrier sheets overlap at an angle on a substrate, the tapered edge of the underlying sheet allows a smooth transition for the overlapping sheet, preventing the formation of an open gap between the barrier sheets and the substrate where air and moisture can penetrate.

Abstract

Gaps between adjacent members in a building construction are sealed by applying a self-adhering barrier sheet to the adjacent members to span the gap. The self-adhering barrier sheet includes a flexible sheet of a barrier material. The flexible sheet has opposing edges, of which at least one is tapered. A pressure sensitive adhesive is applied to at least a portion of at least one major surface of the flexible sheet. The edges of the self-adhering barrier sheet are adhered to the adjacent structural elements by means of the pressure sensitive adhesive. The pressure sensitive adhesive has a thickness equal to or less than the maximum thickness of the flexible sheet. Where two self adhering barrier sheets overlap at an angle on a substrate, the tapered edge of the underlying sheet allows a smooth transition for the overlapping sheet, preventing the formation of an open gap between the barrier sheets and the substrate where air and moisture can penetrate.

Abstract

An article comprises a tube having peripheral areas, including an upper section, a lower section, an inner section, and an outer section, the tube further comprising a tube wall having an inner layer and an outer layer, the inner layer being a semipermeable membrane that is permeable to vapors but impermeable to liquids and the outer layer being a nonwoven fabric, and the tube further comprising at least one inlet port integrated into the tube wall to permit the flow of an activated or activatable foamable composition into the tube interior, wherein the tube further has a plurality of holes that penetrate through the inner and outer layers of the tube to allow expanding foam to both fill the interior of the tube and exit the tube and fill a space exterior to the tube.

Abstract

An article comprising a tube having a length L, a width W and a height H, wherein the tube has peripheral areas comprising an upper section, a lower section, an inner section, and an outer section, and the tube comprises a tube wall having an inner layer and an outer layer, the inner layer being a nonwoven fabric and the outer layer being a semipermeable membrane that is permeable to vapors but impermeable to liquids, wherein the tube has at least one inlet port integrated into the tube wall to permit the flow of fluid into the tube interior, wherein the tube has a through-thickness Gurley air permeability of from 1 to 2,000 seconds, and the tube has a tensile modulus in the L direction of from 300 to 450 MPa and from 200 to 320 MPa in the W direction, and wherein the upper section and/or the lower section of the tube has at least one slot in the outer layer extending at least partially along the length L of tube and centered in said upper and/or lower section, and wherein the inner layer forms the outer surface of the tube in that at least one slot.
