Abstract:
A filter formed essentially from a staple fiber is provided. A nonwoven staple fiber is compressed in to a mat or sheet of selected porosity. The mat or sheet does not include a binder or bicomponent fibers. The staple fibers may be heat treated. The sheet is formed into a selected geometric shape and the staple fibers are thermally fused to bind the staple fibers into a porous filter element. The preferred shape is a helically wound tube or plural sheets, each sheet being self-overlapped and compressed to overlap another sheet. Each sheet is preferably heated and compressed individually and the sheets may be selected to have different porosities and densities.
Abstract:
There is disclosed a liquid filter system that includes a liquid filter apparatus configured to self-clean without removal of the filter apparatus from the filter system. The filter apparatus uses both a filter media for filtering solids as well as a spin motion imparted to fluid being filtered so that centrifugal force can remove solids from the liquid being filtered. The liquid filter system also includes a gas pulse nozzle in fluid communication with the liquid filter apparatus and is configured to flow gas into the filter media to expel water and debris trapped in the filter media without removing the filter media from the filter system.
Abstract:
This disclosure provides systems, methods and apparatus for providing electrical connections through glass substrates. In one aspect, a through-glass via including a peripheral through-glass via hole and sidewall metallization is provided. Sidewall metallization can include multiple conductive lines facilitating increased interconnect density. In another aspect, one or more methods of forming peripheral through-glass vias are provided. In some implementations, the methods include double-sided processes to form aligned via holes in a glass substrate that together form a through-glass via hole, followed by sidewall metallization and dicing through the through-glass via hole.
Abstract:
A filter element having an end cap is provided with a seal that can better accommodate non-round holes. The seal may be a chevron type seal and/or other similar seal having a sealing flange for forming a radial seal. Methods of replacing a filter having an O-ring gasket to improve upon sealing are provided as well as filtration systems employing the filter element.
