Dual Media Filter Cartridge Construction
Dual Media Filter Cartridge Construction
US Patent:
5980759, Nov 9, 1999
Filed:
Jun 7, 1995
Appl. No.:
8/476149
Inventors:
Stephen Proulx - Littleton MA
Frank M. Lentine - Bedford MA
John L. Burns - Dracut MA
Frank M. Lentine - Bedford MA
John L. Burns - Dracut MA
Assignee:
Millipore Corporation - Bedford MA
International Classification:
B01D 2706
US Classification:
210767
Abstract:
A filter cartridge is provided which includes (a) a wound depth filter or a cylindrical seamless depth filter and (b) a pleated filter having a lower micron retention rating than the depth filter. The depth filter and pleated filter surround a central opening. The cartridge is sealed and an appropriate inlet or outlet is provided in order to assure sequential fluid flow first through the depth filter and then through the pleated filter.

2004020, Oct 14, 2004
Filed:
May 3, 2004
Appl. No.:
10/837768
Inventors:
Stephen Proulx - Boxboro MA, US

International Classification:
B01D071/00
US Classification:
210/500210, 210/483000
Abstract:
The present invention relates to a filter element having a non-porous extrusion laminated strip formed on at least one edge and at least one side of a membrane. The strip is used to provide a means for ensuring a good bond between the filter element and the material into which it is potted. The strip is formed by the use of one or more extrusion heads that apply molten or softened polymer to one or both of the surfaces of the filter in a width and height desired. The strip is then subjected to pressure such as through a nip to at least partially embed the polymer strip into the filter pores so as to create a strong mechanical bond between the strip and the filter element. Additionally, it allows for the simultaneous formation of more than one membrane with the edge lamination at the same time.

Filed:
Aug 11, 1993
Appl. No.:
8/105525
Inventors:
Stephen Proulx - Littleton MA
John L. Burns - Dracut MA

Assignee:
Millipore Corporation - Bedford MA
International Classification:
G01N 2702
US Classification:
324 711
Abstract:
A new method and apparatus is described for conducting an integrity test on porous membranes and membrane filters and for conducting a pore-size characterization of membrane. The method and apparatus apply to membrane integrity tests and pore-size characterizations which are based on the dependence on the pore size of the pressure required to intrude a non-wetting, electrically conductive liquid into and through the pores. Electrical-measurement methods are described for identifying the pressure at which intrusion occurs.
