US Patent:

20120125341, May 24, 2012
Filed:

Nov 19, 2010
Appl. No.:

12/949954
Inventors:

Yonas Gebrewold - Woodbury MN, US
Michael K. Domroese - Woodbury MN, US
Dean R. Duffy - Woodbury MN, US
Dwayne D. Daugaard - Hudson WI, US
Nhat Ha T. Nguyen - Woodbury MN, US
David M. Blomberg - Lino Lakes MN, US
Denise A. Barrera - Oakdale MN, US
International Classification:

A62B 23/02
B29C 37/00
B29C 65/00
US Classification:

12820612, 264249, 264138
Abstract:

An filtering face-piece respirator that includes a mask body and a harness . The mask body includes a support structure , filtering structure , and a face seal element . The face seal element is overmolded onto at least a portion of a perimeter of the support structure of the mask body. The overmolding of the face seal member to the support structure allows the face seal to become firmly secured to the mask body at its perimeter.

Filed:

Nov 19, 2010
Appl. No.:

12/949963
Inventors:

International Classification:

A62B 23/02
B29C 45/14
US Classification:

12820612, 264259
Abstract:

A filtering face-piece respirator that comprises a mask body and a harness The mask body includes a supporting frame structure and a filtering structure The frame structure is injection molded onto the filtering structure such that the frame structure becomes bonded to the filtering structure A mask body having such a support structure allows the filtering structure to follow its configuration closely, providing improved aesthetics and collapse resistance to the resulting article.

US Patent:

20130152919, Jun 20, 2013
Filed:

Dec 15, 2011
Appl. No.:

13/326377
Inventors:

Britton G. Billingsley - St. Paul MN, US
David M. Blomberg - Lino Lakes MN, US
Joy L. Manske - Menomonie WI, US
International Classification:

A62B 7/10
US Classification:

12820125, 12820612
Abstract:

A filtering device that includes a housing having a plurality of subsections , and where each subsection is adapted to receive a filter element , and . An inlet is disposed at a first location on the housing , and an upstream air distribution system is placed in fluid communication with the inlet and with each of the subsections , and . A downstream air distribution system is located in fluid communication with each subsection , and , and an outlet in fluid communication with the downstream air distribution system. The upstream and downstream air distribution systems are constructed to cause the same airflow velocity through each subsection. Using such a construction, overall product service life may be increased while minimizing pressure resistance of the total filter.

Appl. No.:

13/326451
Inventors:

International Classification:

A62B 7/10
US Classification:

12820125, 12820612
Abstract:

A filtering device that includes a housing having a plurality of subsections , and where each subsection contains a filter element , and . An inlet is disposed at a first location on the housing , and an upstream air distribution system is placed in fluid communication with the inlet and with each of the subsections , and . A downstream air distribution system is located in fluid communication with each subsection , and , and an outlet is in fluid communication with the downstream air distribution system. The subsections are fashioned such that each subsection , and is not in fluid communication with each other. Using a filtering device so constructed, airflow through the device may be better managed to enable overall product service life to be increased while minimizing pressure resistance of the total filter.
