Patent number: 6235072Abstract: A glove box filter system for filtering out particles from a glove box environment defined in a glove box having an outlet and an inlet. The filter system includes a first filter stage for receiving removed gas from the glove box environment. The first filter stage contains a chamber having a first filter through which the removed gas passes for filtering out particles contained in the removed gas. The filtered gas is provided to a circulation conduit connected to a blower for providing movement of the gas through the glove box environment. A second filter stage connected to the glove box inlet is provided for fine-filtering the gas passed by the first filter stage prior to the return of the gas to the glove box environment. The first filter stage is connected to the glove box environment through one or more valves which isolate the first filter stage from the glove box environment when replacement of a first filter contained in the first filter stage occurs.Type: GrantFiled: August 25, 1999Date of Patent: May 22, 2001Assignee: Agere Systems, Inc.Inventors: Nonna Kopylov, Ahmet Refik Kortan

Patent number: 6174349Abstract: A method and apparatus is provided which continuously filters scrubbed gases prior to emission to the atmosphere. In particular, the method and apparatus can continuously scrub the effluent stream from a chemical vapor deposition process, such as the process used to deposit epitaxial silicon. In order to provide this continuous scrubbing, a separation housing having a filter housing is provided that permits the filter to be replaced during and without interruption of the scrubbing and filtering process. The filter housing can define a pair of tracks that guide the insertion and removal of a filter such that inserting a clean filter into one end of the pair of tracks causes a spent filter to be pushed out of the opposed end of the tracks as the clean filter is slid down the tracks.Type: GrantFiled: April 6, 1999Date of Patent: January 16, 2001Assignee: SEH America, Inc.Inventor: Gennaro Nicholas DeSantis
