Title: Systeme d'alimentation de fluide avec liaison de montage
Inventor: WARNER ERIC A
IPC: F04B43/02
Filed: 1995-09-07
Granted: 2000-04-04
Abstract: Système d'alimentation en fluide où la plaque de pression d'un conduit de fluide est montée de manière fixe sur une pompe et le mécanisme de pompage est mobile par rapport à la plaque (32) pour contrôler la force appliquée au conduit. Un système de déplacement comprenant une tringlerie à quatre barres (48, 50, 52, 54) retient le mécanisme de pompage mobile dans une orientation prédéterminée par rapport au conduit et dans toute la plage de mouvement du mécanisme. Le mécanisme de pompage est actionné par ressort (63) en direction du conduit (30). Les doigts péristaltiques (22) du mécanisme de pompage sont situés dans des guides, le moyen d'entraînement de ces doigts étant monté de manière rigide sur ce guide. S'il y a empêchement de mouvement d'un des doigts ou de plusieurs de ces doigts dans leurs guides respectifs, le mécanisme d'entraînement sera arrêté et le mécanisme de pompage s'arrêtera plutôt que de se dégager et de permettre une circulation libre.

Title: Method and apparatus for purifying a substance
Inventor: WHITLOCK WALTER H
IPC: B01D3/26
Filed: 1997-04-22
Granted: 2000-08-01
Abstract: A method and apparatus for purifying a substance in which the substance is rectified within first and second distillation columns to produce a tower overhead in the second distillation column, lean in both heavy and light impurities. The column bottoms produced within the second distillation column is boiled to provide boil-up within the second distillation column, thereby to initiate formation of an ascending vapor phase. A vapor stream is removed from the second distillation and then fed into a bottom region of the first distillation column to initiate formation of the ascending vapor phase therein. The vapor stream removed from the second distillation column is formed from the ascending vapor phase produced within the second distillation column. The second distillation column is reboiled by a reboiler that can include a reservoir containing a heat exchange fluid that condenses against boiling the column bottoms provided in the second distillation column. The type of heat exchange fluid utilized is selected to have a condensation temperature above bubble point temperature of the column bottoms of the second distillation column.

Title: Wrinkle reducing composition
Inventor: WARD THOMAS CARL
IPC: D06M23/06
Filed: 1995-10-31
Granted: 2001-08-07
Abstract: The present invention relates to a wrinkle reducing composition for use on fabrics, particularly clothing. The composition comprises a wrinkle reducing active, which is made up of an effective amount of silicone and an effective amount of film-forming polymer, and a liquid carrier. The composition is substantially free of starch, modified starch, and mixtures thereof, and results a Loss Modulus Difference of greater than about 3.3 x 107 Pascal on fabric. The composition can be incorporated into a spray dispenser that can create an article of manufacture that can facilitate treatment of fabric with the wrinkle reducing composition. The wrinkle reducing actives in the composition can be determined through Dynamic Mechanical Analysis using a 100 % cotton broadcloth swatch and a fixed volume of a sample of wrinkle reducing active.

Title: Drilling compositions and methods
Inventor: HAND BARRY
IPC: E21B33/138
Filed: 1996-06-28
Granted: 2009-06-23
Abstract: The materials include non-polyampholite crosslinked polymers and gels based on a polymer which in uncrosslinked form is substantially soluble in ionic fluids and substantially insoluble in water.  The materials change their state of hydration in response to an environmental trigger. The disclosed materials are useful as drilling, completion or workover fluids in wells such as hydrocarbon producing wells. According to the disclosed method, crosslinked polymers or gels are introduced into a stratum, blocking or bridging the pores of the stratum. Thereafter, an environmental condition is changed to cause the hydrated material to become less hydrated to unblock the pores allowing production from the well.

Filed: 1997-07-24
Granted: 2010-01-05
Abstract: A method for enhancing the dissolution properties of relatively insoluble dietary supplements is provided in accordance with the invention. The method includes the steps of providing at least one relatively water-insoluble dietary supplement, solubilizing the dietary supplement with a solubilizer, and incorporating an edible polyhydric alcohol into the solubilized dietary supplement to provide a liquid dietary supplement composition that will dissolve spontaneously in the gastrointestinal tract with the minimum agitation which normally occurs there due to peristaltic action. The liquid dietary supplement composition can be readily supplied by incorporation in a gelatin capsule and a gelatin capsule having a liquid dietary supplement incorporated therein is also provided in accordance with the invention.  The gelatin capsule dissolves readily in the digestive tract and the dietary supplement has enhanced bioavailability in comparison to prior art gelatin capsules.

Title: Interlock for electrical switching apparatus with stored energy closing
Inventor: DORAN RAYMOND CLYDE
IPC: H01H3/02
Filed: 1999-05-07
Granted: 2008-02-19
Abstract: Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are closed or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by aflat on the cam shaft. Rotating shafts are journalled solely in confronting apertures in the side plates. The cam shaft is captured between bushings seated in non-circular openings in the side plates thereby eliminating the need for any fasteners. Likewise, other parts mounted between the side plates and joined by pins having enlarged heads retained by the side plates do not need retainers. Various shafts extending between the side plates have reduced diameter ends of progressive lengths for successive insertion in one side plate to aid in assembly of the operating mechanism.
