Abstract: A collar (500) for injecting fluid, such as a formation treating fluid, into a wellbore, and a method for using same. The collar is disposed between the upper and lower packing elements (40, 41) of a pack-off system during the treatment of an area of interest within a wellbore. The collar first comprises an inner mandrel (550) running essentially the length of the collar. The inner bore of the collar is in fluid communication with the annular region between the collar and the surrounding perforated casing by a set of actuation ports (552). A second set of ports (554), known as frac ports, is disposed within the mandrel. In accordance with one aspect of the invention, the collar further comprises a tubular case which substantially seals the frac ports in a first position, and slidably moves along the outer surface of the mandrel in order to expose the frac ports in a second position. In operation, the upper and lower packing elements are set at a first fluid pressure level. Upon application of a second greater fluid pressure level, the upper and lower packing elements are further separated in accordance with a designed stroke length, thereby exposing the frac ports.

Granted: 2007-04-10
Abstract: Disclosed is a seal assembly for dynamically sealing between rotatable members such as a rolling cone of a rock bit. The assembly includes a seal ring having a facing surface of a relatively hard material, such as hardened steel or tungsten carbide, and a second seal ring of a softer material, the softer material being harder, however, than typical elastomers. Suitable materials for the relatively soft seal ring include tin, copper, aluminum, magnesium, lead and alloys thereof, as well as non-metallic materials such as nylon-zytel, acetal, and polypropylene. The relatively soft seal ring may be affixed to a third seal ring or maybe affixed directly to the cone steel, for example. The seal assembly provides potential for longer life relative to elastomeric seals and requires less axial space along the journal surfaces than certain conventional metal seal assemblies.

Title: Automatically retractable needle safety syringe
Inventor: VAN DYKE LEWIS R
IPC: A61M29/00
Filed: 2002-02-27
Granted: 2010-06-15
Abstract: An automatically retractable needle safety syringe apparatus (10) having an integral safety feature that automatically and immediately retracts the piercing tip end (78) of the needle body (16) after a single use, due to a punch (70) which frictionally engages the foundation of the ferrule (84) and a vacuum created within the syringe body (12) during the process of injecting fluid therefore causing the piercing tip end (78) and the needle body (16) to permanently reside enclosed within the syringe body (12) protectively pressed against the inner surface (28) of the tube (18) thus alleviating needle reuse and accidental needle prickings with contaminated syringe needles and therefore ultimately preventing the transmission of blood-borne pathogens and other diseases by contaminated syringe needles. The method of operation is also disclosed.

Title: Methods and apparatus for uniquely identifying a large number of film prints
Inventor: BELL ALAN
IPC: G06F21/10
Filed: 2003-03-31
Granted: 2009-08-25
Abstract: A method and apparatus for generating many uniquely identifiable media copies from a few uniquely marked masters to reduce the expense of subjecting each media copy to a marking process while maintaining the ability to trace unauthorized copies back to an authorized source. A number of masters of a film or media presentation are digitally or optically marked with identifiers to distinguish each master from each other master. The identifiers provide the ability to distinguish corresponding partitions of segments among masters. The masters with their identifiers are then duplicated. Final media prints are then assembled by combining segments with the duplicated identifiers from various masters in a manner to form segments with unique identifier sequences. Thus, each final print may be distinguished from each other final print by their identifier sequences.

Granted: 2012-01-17
Abstract: Provided herein are methods for determining the metabolism of one or more sugars and/or fatty acids, and applications thereof. Such applications include determining the rate of glycogen synthesis and glycolysis, which are believed to be early markers for predicting elevated risk of diabetes and cardiovascular disease. Other applications include methods for screening drugs that effect sugar and/or fatty acid metabolism. The methods are useful for at least partially characterizing drugs for desirable or undesirable (toxic) characteristics. Drugs that are at least partially characterized using the methods of the invention can then be further developed in preclinical testing and clinical trials. Such drugs may be found to be useful in treating obesity, diabetes, cardiovascular disease, and other disorders of metabolism.
