Title: Method and apparatus for removing gas from drilling mud
Inventor: RAMOS DANIEL A
IPC: B01D19/00
Filed: 2001-07-03
Abstract: An apparatus and method that is used for removing gas from drilling mud coming from gas and oil well-bores. The apparatus receives the gas ladened drilling mud and utilizes the energy from the gas ladened mud to power blower fans that are used to discharge any released gas. A set of conical trays are used to catch the gas ladened mud that is dispersed in the energy utilization by a set of helical blades. The gas ladened mud will slowly flow down the conical trays and liberate gas with the assistance of a partial vacuum that is within the reaction vessel. A liquid trap is also formed in the bottom portion of the reaction vessel, to prevent air from entering the reaction vessel. The gas generated is expelled out of the reaction vessel and burned off by a flare line or simply released into the outside air.

Inventor: WHITE DONALD JAMES JR
IPC: A61K9/68
Filed: 2000-06-22
Abstract: The present invention relates to chewing gum composition comprising a polymeric surface active agent. A second aspect of this invention relates to a crunchy chewing gum wherein the crunchy texture is provided by particulate polyphosphate particles within the formulation and which lasts through the initial minutes of mastication. The chewing gum composition may also contain a cationic material and/or an orally active metallic ion.

The surface conditioning effects can be measured through in vitro or in vivo testing. The in vitro testing shows a total surface energy and/or a lewis base score to increase immediately after treatment with the chewing gum and then decrease over time. The in vivo testing shows a water contact angle of the oral mucosa to decrease after treatment with the chewing gum composition and/or a significantly higher smooth teeth feel relative to other chewing gum compositions. The present invention also relates to methods of providing surface conditioning effects to a subject comprising administering to the subject a chewing gum comprising a polymeric surface active agent. The present invention also relates to methods of reducing astringency of a chewing gum containing an orally active metallic ion without significantly reducing the efficacy of the metallic ion.
