US Patent:

7306659, Dec 11, 2007

Filed:

Aug 13, 2004

Appl. No.:

10/918254

Inventors:

Darlene K. Gorton - Elkton MD, US
Earl R Ball - Middletown DE, US
Edwin George Dauber - Chesapeake City MD, US

Assignee:

Gore Enterprise Holdings - Newark DE

International Classification:

B01D 53/04
G11B 33/14

US Classification:

96134, 96139, 553856, 360 9702

Abstract:

The invention relates to a device for filtering contaminants, such as particulates and vapor phase contaminants, from a confined environment such as electronic or optical devices susceptible to contamination (e. g. computer disk drives) by improving performance and possibly incorporating multiple filtration functions into a unitary filter. The filter includes flow layers which improve filter performance. Filtration functions include a passive adsorbent assembly and can include a combination of inlet, or breather filter and adsorbent filter. Moreover, recirculation filter, diffusion tube and outside mount functions can be added to the filter depending on desired functionality within the enclosure.

US Classification:

96121, 96135, 96147, 96154, 553856, 360 9702

Abstract:

A compact sorbent filter for selectively sorbing contaminants and method of removing contamination from an enclosure with a filter is disclosed. Filters of the present invention comprise two or more modular adsorbent units that can be foldably connected and possibly symmetric about one or more axis. In another aspect, the invention provides a laminar support, having at least one edge, a first side and a second side opposite the first side, wherein the article is folded along the fold line about the at least one edge of the laminar support such that the first adsorbent assembly is adjacent to the first side of the laminar support and the second adsorbent assembly is adjacent to the second side of the laminar support. In this aspect, the laminar support may be exposed or covered by the adjacent adsorbent assemblies.

International Classification:

F24F 3/14

Abstract:

Systems including a moisture pump for removing moisture from an inside environment to an outside environment. The moisture pump includes a housing defining a heating chamber and a condensation chamber. Maintained by the housing is a desiccant, a heater, and a heat sink for selectively adsorbing water vapor in the heating chamber when the heater is off and desorbing water vapor into the heating chamber when the heater is on. A valve assembly is also maintained by the housing transitionable between an adsorption position and desorption position. The adsorption position allows water vapor to be selectively transmitted into the heating chamber from the inside environment. The desorption position allows water vapor to be transmitted from the heating chamber into the condensation chamber for transmission into the outside environment, respectively. Insulation is optionally used around the heating chamber to increase desiccant desorption efficiency.
