Patent number: 9676142Abstract: Systems and kits for decorating walls include a plurality of décor assemblies and a plurality of complementary fastening structures. The décor assemblies include a décor element and a releasable fastening structure providing first fastening elements. The complementary fastening structure includes a base, a pressure sensitive adhesive disposed on the base, and second fastening elements. The first fastening elements are releasably mateable with the second fastening elements to define a releasable fastening system. During use, a complementary fastening structure is releasably applied to a wall, and is connected to and supports one of the décor assemblies via the releasable fastening system.

Patent number: 8424707Abstract: 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.Type: GrantFiled: October 16, 2008Date of Patent: April 23, 2013Assignee: 3M Innovative Properties CompanyInventors: Laurence W.

Patent number: 7736504Abstract: 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.Type: GrantFiled: June 9, 2008Date of Patent: June 15, 2010Assignee: 3M Innovative Proerties CompanyInventors: Karl Fritze, Nathan E.
