Title: Catalytic filter material and method of making same
Inventor: BRINCKMAN GLENN A
IPC: D03D1/00
Filed: 1996-06-07
Abstract: The present invention is an improved catalytic filter material for use in removing contaminants such as NOx from a fluid stream . The filter of the present invention employs composite fibers of expanded polytetrafluoroethylene (PTFE) filled with catalytic particles. The composite fibers are chopped into staple fibers and made into a felt material. Preferably, the felt material is then laminated on at least one side with a protective microporous membrane.  The combined filter removes both macro-particles, such as dust, from the filter stream before the dust can clog active catalytic sites and effectively catalytically converts undesirable contaminants in the fluid stream to acceptable end products.

IPC: A61M5/168
Filed: 1996-09-11
Abstract: Un robinet-vanne à manchon sensible à la tension se compose d'un élément de robinet-vanne à manchon flexible élastiquement et d'une longueur de tubulure flexible combinés présentant une section destinée à être fermée automatiquement par déformation au niveau du point de pincement ou de vrillage, fermant ainsi la lumière lorsque la partie déformée n'est pas soumise à une tension longitudinale. L'élément de robinet-vanne à manchon est associé longitudinalement à la partie de tubulure et présente de préférence deux parties terminales reliées par une partie de tige. Les parties terminales sont fixées à la partie de tubulure en des points espacés longitudinalement de la tubulure flexible, de sorte que la longueur de la partie enveloppée est beaucoup plus longue que la partie de tige de l'élément de robinet-vanne à manchon. Si la limite élastique apparente de la partie de tige est supérieure à la résistance à la courbure de la tubulure flexible, la partie enveloppée de la tubulure flexible ne sera par courbée sur le point d'occlusion lorsque ladite partie n'est pas soumise à un tension, mais permettra le passage d'un liquide lors de l'application d'une tension de dévrillage longitudinale.

IPC: B65B35/20
Filed: 1997-03-26
Abstract: An apparatus (10) for loading stacked article groups (14) into cartons (16) in a continuous motion cartoner assembly (12). The barrel cam loading apparatus (10) or article group transport mechanism (24) is particularly suited to loading article groups that are unstable or whose articles tend to spin and kick articles out of the carton. The article group transfer mechanism (10) loads the stacked group by having the lower article group (36) lead the upper article group (40) which tends to make the articles tip backward into a stable contact with the article group transfer mechanism, and by forming the upper article group into a nested configuration which has a thinner loading dimension and resists kicking out an article.

Inventor: WILLIAMS DANIEL J
IPC: G01J3/02
Filed: 1998-10-30
Abstract: The present invention relates to a method of viewing and processing hyper-spectral image data compressed using a VQ algorithm. According to the invention the data is compressed using a codebook of codevectors including binary spectral vectors, which allows processing of the compressed data and viewing of data within a datacube without expanding the compressed data into the complete datacube. In order to view an image derived from a datacube, for each pixel within the image a location within the datacube is selected, an index value from the index map at that location is retrieved, and a spectral value from a spectral vector within the codebook is retrieved for said pixel, the spectral vector identified by the retrieved index. A single spectral vector is easily viewed by displaying a spectral vector from the codebook.
