International Classification:

F16L 13/00

US Classification:

285 211, 2851244, 285256, 2852861

Abstract:

A connector assembly for creating a plastic tube joint in a length of plastic tubing having a distal end, a proximal end and a hollow lumen includes forming a flare in the tube proximate the proximal end thereof by means of a flared ferrule disposed in the lumen and defining a void between the flare and the proximal end of the tubing, the void being defined between the ferrule and a collet, the tubing contracting into the void, and forming a neck between the ferrule and the collet proximate the ferrule flare, the neck substantially permanently capturing the tubing contracted into the void; and substantially permanently bonding the collet to a connector body. A connector assembly for simultaneously forming a plastic tube joint in a pair of plastic tubes is further included as is a method for simultaneously forming a plastic tube joint in a pair of plastic tubes.

International Classification:

B01D 27/10

US Classification:

210238, 2103216, 210443, 210450

Abstract:

A crossflow filtration system including at least one quick dry change crossflow filtration cartridge designed to rotatably interface with a manifold assembly. The quick dry change crossflow filtration cartridge can comprise a membrane element, for example an ultrafiltration membrane, microfiltration membrane, nanofiltration membrane or reverse osmosis membrane element enclosed within a housing. The quick dry change cartridge includes an inlet stream, a permeate stream and a concentrate stream. The manifold assembly includes three similar flow paths; an inlet stream, a permeate stream and a concentrate stream. When engaged, the cartridge and manifold assembly define continuous inlet flow paths, permeate flow paths and concentrate flow paths that connect across the interface. Thus, all of the connections to the water filtration system can be made onto the manifold, and the resulting connected system is compact and easy to connect.

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

B65D 90/02

US Classification:

220563, 62 98

Abstract:

A liquid storage tank assembly includes a baffle member and a tank assembly. The baffle member includes a generally helical or spiral shaped portion. The baffle member defines a spiral flow path between inlet and outlet openings of the tank assembly. When the baffle member is positioned within the tank and the tank assembly holds a volume of a first liquid, input of a supply of a second liquid at the inlet to the tank assembly forces the first liquid along the spiral flow path and out of the tank assembly exit without substantial mixing of the first and second liquids before substantially all of the first liquid has been dispensed.

International Classification:

F16L013/02

US Classification:

285/340000, 285/021100

Abstract:

An apparatus for creating a permanent and fluid tight tube joint in a length of plastic tubing, the tubing including a terminal end, the apparatus including a manifold for receiving the plastic tubing, the manifold including structure defining a first counterbore presenting a tubing terminal end engaging face, structure defining a second counterbore presenting a seal engaging face, and the manifold further presenting a manifold coupling face. A seal is receivable within the second counterbore and a gripping element is receivable within the manifold and adapted for fixedly engaging the tubing. A retainer includes a compressive member and a retainer coupling face, the retainer compressive member receivable within the second counterbore for operably, compressively engaging the seal. The retainer coupling face and the manifold coupling face are mutually abuttably oriented when the retainer compressive member is received within the second counterbore, whereby the manifold coupling face and the retainer coupling face can be operably fixedly coupled together to permanently attach the retainer and manifold together with the seal compressed to provide a fluid tight coupling of the tubing with the manifold.

Abstract:

A crossflow filtration system including at least one quick dry change crossflow filtration cartridge designed to rotatably interface with a manifold assembly. The quick dry change crossflow filtration cartridge can comprise a membrane element, for example an ultrafiltration membrane, microfiltration membrane, nanofiltration membrane or high-flux reverse osmosis membrane element enclosed within a housing. The quick dry change cartridge includes an inlet stream, a permeate stream and a concentrate stream. The manifold assembly includes three similar flow paths; an inlet stream, a permeate stream and a concentrate stream. When engaged, the cartridge and manifold assembly define continuous inlet flow paths, permeate flow paths and concentrate flow paths that connect across the interface.
