Title: Multi-piece rotary cone drill bit seal
Inventor: PORTWOOD GARY R
IPC: E21B10/25
Filed: 1999-04-01
Granted: 2007-06-26
Abstract: Multi-piece Seals of this invention comprise an annular seal body that is formed from an elastomeric energizing material, and that has a static seal surface along one surface and a contacting surface along another surface. A remaining seal portion in the form of a seal jacket or seal cap is connected to the seal body along the contacting surface to provide a dynamic sealing surface thereto. The seal jacket or cap is formed from a material that is different from the seal body and, more specifically, from a material that displays improved wear resistance when compared to the seal body. A preferred seal jacket or cap material is a composite construction comprising a nonelastomeric polymer fabric that is impregnated with an elastomeric material. The seal jacket or cap is configured to connect with the seal body by mechanical attachment means independent of chemical cross-linked bonding. Multi-piece seals of this invention can be formed from two components, e.g., the seal body and the seal jacket or seal cap, or can be formed from three or more components, e.g, the seal body, seal jacket or cap, and one or more stiffening supporting members interposed therebetween.

Granted: 2002-03-05
Abstract: The present invention provides a element row for a slide fastener obtained by stamping a monofilament made of synthetic resin, wherein coupling heads are shaped into peculiar coupling configurations so as to enable the elements to be reliably coupled with each other even if gaps between upper and lower leg portions are small and the element is durable and has a sufficient coupling function, and provides a method and an apparatus for producing the element. Each coupling head of a continuous element row (ER) molded by stamping has flat sectional portions each extending from center portions of one ends of the upper and lower leg portions toward each other with widths increasing in an longitudinal direction of the elements and coupling portions which are sandwiched between both the flat sectional portions, extending along opposed end edges of the flat sectional portions, thinner than the flat sectional portions, and have tip end portions projecting toward opposite sides in the longitudinal direction of the element row (ER), and the coupling portion is reliably engaged in a small gap formed between the coupling heads and the upper and lower leg portions of the adjacent elements of a mating element row at the time of coupling with the mating coupling element rows (ER) in a state that the upper and lower leg portions of the element row is fixed to fastener tape substantially in close contact with each other. Therefore, a coupling split or the like is not generated. slide fastener

Abstract: A method and system for the dynamic presentation of the contents of a plurality of documents on a display is disclosed. The method and system comprises receiving a plurality of documents and providing a plurality of topically rich capsule overviews corresponding to the plurality of documents.  The method and system also includes dynamically delivering document content encapsulated in the plurality of capsule overviews. In so doing, a system and method in accordance with the present invention can present thematic capsule overviews of the documents to users. A capsule overview is derived for the entire document, which will depict the core content of an average length article in a more accurate and representative manner thaw utilizing conventional techniques. The capsule overviews, delivered in a variety of dynamic presentation modes, allow the users to quickly get a sense of what a document is about, and decide whether they want to read it in more detail. If so, the system and method greatly facilitate the process of focused navigation into the parts of the document which may be of particular interest to the user. In a preferred embodiment, the capsule overviews include a containment hierarchy which relates the different information levels in a document together, and which includes a collection of highly salient topic stamps embedded in layers of progressively richer and more informative contextualized text fragments. The novel presentation metaphors which the invention utilizes are based on notions of temporal typography, in particular for exploiting the interactions between form and content.

Title: Process for recovery and purification of saponins and sapogenins from quinoa (chenopodium quinoa)
Inventor: THOMPSON KRISTA
IPC: C07H1/08
Filed: 1999-04-16
Granted: 2008-02-12
Abstract: The invention relates to a process for commercial extraction of saponins from quinoa, and optionally for the formation of corresponding sapogenins.  The saponin extraction process comprises contacting a saponin-containing part of a quinoa plant (e.g. quinoa bran or seeds) with an aqueous alcohol solution containing an alcohol selected from methanol and ethanol to form a saponin-containing solution and an extracted solid residue, removing the alcohol from the saponin-containing solution to leave a saponin-containing aqueous solution, and evaporating water from the saponin-containing aqueous solution to produce a saponin-containing product.  The conversion to sapogenins involves obtaining a solution of saponins in an aqueous alcohol, adding a strong acid to the solution to hydrolyze the saponins to form corresponding sapogenins that precipitate out of the solution as a precipitate, recovering the precipitate, and decolorizing the precipitate by forming a slurry of the precipitate with a solution of an aqueous base to form a decolorized sapogenin product. The processes of the invention permit efficient saponin extraction, and sapogenin production, on a commercial scale using inexpensive materials and techniques.
