Abstract: A three-part epoxy grout composition comprises a liquid epoxy blend, a liquid hardener, and a graded particulate aggregate, wherein the dry aggregate particles are pretreated with an applied adhesion promoter in an amount of 0.01 to 5% by weight. The volume of pretreated aggregate particles, when mixed with the epoxy blend and the hardener, comprises at least 70% by volume of the cured grout. Pretreatment of the aggregate by coating with adhesion promoter allows more efficient use of chemicals along with improved strength. Related methods are also disclosed.

Abstract: Z-filters capable of cleaning particulate matter from airflow streams in dust collectors, including reverse flow, reverse air, and reverse pulse systems.

Abstract: An apparatus and method are provided for dispensing gas to a fluid, such as a beverage, through a delivery system from a vessel containing the gas into another vessel containing the fluid.

Abstract: An apparatus and method for delivering oxygen, oxygen enriched air, or air through a delivery system from one vessel containing a higher pressure concentration of the gas into another vessel containing a liquid at atmospheric pressure introduced through a diffuser or dispersion nozzle including one or more passages in a controlled regulated manner. This process and apparatus provide the liquid with an oxygenation level for improved flavor in a short amount of time.

Abstract: A query device for conducting automated user identification using a domain specific query language is described. The domain specific language is a computer language specially adapted for use in the healthcare domain. The domain specific language includes specific syntax suitable to the medical or healthcare industries, and is structured in the form of a string for processing. The domain-specific query is automatically processed and delineated into one or more processing sections. The domain-specific query is specifically structured for improved efficiency through iterative processing of the one or more processing sections, where each of the one or more processing sections is classified and mapped to a specific filter. Each filter represents a programmatic mechanism for automatically conducting a query against one or more backend data storages or other datasets to return a list of users or equipment that meet the criteria of the filter. Corresponding methods, and computer readable media are described.

Abstract: A portable, adaptable gaming surface for use in strategy games and planning boards is disclosed which comprises tiles the surfaces of which are printed with grids and are compatible with the use of dry-erase markers for drawing upon such tile surfaces. Tiles comprise means of interconnecting with other like tiles, preferably using jigsaw-puzzle-like tabs extending from at least two edges of such tile, and cut-outs, configured to receive such tabs receding into two opposing edges of such tile.
