Patent number: 8070945Abstract: A filtration module is provided which includes a manifold (100), a filtration cartridge (104) and a bowl (102) that houses the filter cartridge. The filtration cartridge and bowl are connected to each other to form a unitary construction. The filtration cartridge and bowl are in fluid communication with the manifold in a manner which prevents mixing of a fluid feed to the module and a permeate removed from the module.Type: GrantFiled: June 27, 2008Date of Patent: December 6, 2011Assignee: Entegris, Inc.Inventors: Ralph J.

Publication number: 20090200222Abstract: A filter container comprises a top cap, and a bowl formed of a rigid material. The top cap includes a top cap flange that includes a first path around at least a portion of the top cap flange. The bowl includes a bowl flange that includes a second path around at least a portion of the bowl flange. At least one of the first path and the second path include a reduced thickness of material by comparison with surrounding material. The first path is at a different radial distance from a central axis of the filter container than the second path around the extent of both the first path and the second path, such that exerting a force on an opening member creates a tear through the top cap flange and bowl flange, the tear forming between the first path and the second path and allowing opening of the filter container.Type: ApplicationFiled: January 13, 2009Publication date: August 13, 2009Inventors: Mauro G. DelleMonache, Ralph J. Stankowski

Patent number: 7247245Abstract: A depth filter design is disclosed which has little if any open void area upstream of the media. Preferably, it also has little if any open void area downstream of the media as well. A preferred embodiment uses layers of stacked, fibrous media with several of the layers being separated from the others by spacers which serve to compress the media and to prevent the bypass of fluid around the media adjacent the inner wall of the housing. Several designs for attaching the end caps which allow for the compression of the media are also disclosed.Type: GrantFiled: December 2, 1999Date of Patent: July 24, 2007Assignee: Entegris, Inc.Inventors: Stephen Proulx, George Perivolotis, Zhenwu Lin, Gregory Straeffer, George A. Gagne, Kenneth King, Ralph J. Stankowski

Publication number: 20040159600Abstract: A filtration module (1) is provided which includes a manifold (3), a filtration cartridge (50) and a bowl (2) that houses the filter cartridge (50). The filtration cartridge (50) and bowl (2) are connected to each other by a snap fit construction (22) to form a unitary construction. The filtration cartridge (50) and bowl (2) are in fluid communication with the manifold (3) which prevents mixing of a fluid feed to the module (1) and a permeate removed from the module (1).Type: ApplicationFiled: December 15, 2003Publication date: August 19, 2004Inventor: Ralph J Stankowski

Patent number: 6635175Abstract: A filter cartridge housing formed of a manifold and a bowl containing a filter cartridge is disclosed. The filtration cartridge and bowl are connected to each other to form a unitary construction. The filtration cartridge and bowl are in fluid communication with the manifold in a manner which prevents mixing of a fluid feed to the module and a permeate removed from the module. A threaded ring substantially fixed in a position relative to either the bowl or the manifold is used to positively drive the manifold and bowl together and apart as needed and to form a secure and liquid tight seal between the two components when they are together. The threaded ring is held by a key in the keyway on of the outer surface of the bowl or manifold. The threads of the ring mate with the threads on the manifold or bowl. As the ring is relatively fixed by the key/keyway to its position on the bowl or manifold, it moves the bowl relative to the manifold as the ring is rotated onto or off of the mating threads.Type: GrantFiled: June 28, 2001Date of Patent: October 21, 2003Assignee: Mykrolis CorporationInventor: Ralph J.

Patent number: 5439587Abstract: A self-priming filter holder for filtration of intravenous liquids is provided and is formed of one or two housing portions sealed to a core portion. The core portion has one or two ribbed surfaces forming a plurality of flow paths sealed at one end and open at a second end and at least one channel preferably larger than the flow paths. The channel(s) is in fluid communication with the flow paths and an outlet. An inlet is provided to the interior of the housing portion(s) which are sealed from the ribbed surfaces by hydrophilic membranes. The housing portion(s) can be provided with gas vents sealed with hydrophobic membranes. Fluids pass through the flow paths in one direction and through the channel(s) in an opposite direction to remove gas from the flow paths and channels prior to use.Type: GrantFiled: July 27, 1993Date of Patent: August 8, 1995Assignee: Millipore CorporationInventors: Ralph J.

Patent number: 5269917Abstract: A filtration apparatus formed by ultrasonically welding a top section to a base section with a filtration membrane interposed there between. One of the top section or base section has a plurality of radially extending energy directors and the other of the top section or base section has a circumferentially extending energy director in contact with the radially extending energy directors where ultrasonic welding is effected. The groove cosiverts some of the peeling load into texisle load.Type: GrantFiled: February 28, 1992Date of Patent: December 14, 1993Assignee: Millipore CorporationInventor: Ralph J. Stankowski
