| 20110198301 | Modular Filter Assembly - Disclosed herein are modular filter assemblies having a plurality of stacked filter plates formed from a porous material. The filter plate can comprise a planar base portion from which a convoluted ridge wall, having a ridge outer side surface, a ridge inner surface, and a top ridge surface extends. A plurality of fluid inlet troughs and a plurality if fluid outlet troughs are defined by the ridge wall. Adjoining filter plates form a plurality of fluid inlet cavities defined by the fluid inlet trough of one filter plate and a portion of the bottom surface of the adjoining filter plate; and a plurality of fluid outlet cavities defined by the fluid outlet trough of the one filter plate and a portion of the bottom surface of the adjoining filter plate. In use, the plurality of fluid inlet cavities are in filtered communication with the plurality of fluid outlet cavities. | 08-18-2011 |
| 20100176210 | Hydrophilic Porous Wicks for Vaporizable Materials - This invention provides a hydrophilic porous fiber wick for delivering vaporizable material into the atmosphere, such as a room environment. The wick may be biodegradable. The wick is comprised of a sintered synthetic bicomponent fibers, optionally combined with synthetic monocomponent fibers or natural monocomponent fibers. The wick is optionally treated with plasma or finishing agents for improved hydrophilicity. The wick can wick aqueous and/or non-aqueous-based fragrances or other vaporizable materials and evaporate them into the air without the use of heat, convection air, or atomization. | 07-15-2010 |
| 20100104845 | Composite PTFE Materials and Applications Thereof - The present invention provides sintered composite polymeric materials and methods of making and using the same. The sintered composite polymeric materials are made by sintering composite particles comprising a polytetrafluoroethylene component and a carbonaceous component, wherein the carbonaceous component is dispersed throughout the polytetrafluoroethylene component. | 04-29-2010 |
| 20090019955 | Disposable Pipette and Methods for Making and Using the Same - The present invention provides inexpensive pipettes and related structures offering high precision while minimizing the effects of operator error and chances of cross-contamination. In one embodiment, a pipette comprises a suction apparatus and a hollow body comprising a sample collection chamber, the sample collection chamber open at a first end and closed by a porous barrier material intermediate to or at a second end opposite the first end, wherein the suction apparatus is coupled to the hollow body. | 01-22-2009 |
