Abstract: An oilfield tubular string (10, 60, 60A) comprising a plurality of elongated joints having one or both ends threaded. The joints may be connected by a coupling including a generally sleeve-shaped coupling body having a tapered upstream thread profile and a tapered downstream thread profile for threaded engagement with a mating profile of a respective joint. The coupling body includes a low stress flex groove (30) having a selected box thread runout bevel angle, and all transitions in the flex groove between surfaces are radiused to greater than 0.100 inches to minimize stress risers. A pin-in-box connection between tubular joints includes mating tapered threads (72), engagement of end shoulder (74, 76, 78, 80), and a low stress flex groove (82). The present invention allows the elongate joints to be used as both a casing string and a drill string, thereby saving significant time and expense.

Title: Artificial tear composition containing a combination of three demulcents
Inventor: CHOWHAN MASOOD A
IPC: A61K9/08
Filed: 2001-12-13
Granted: 2008-02-05
Abstract: Improved artificial tear compositions are described. The compositions are preferably formulated as sterile, isotonic solutions. The solutions contain a unique combination of three demulcents. The solutions preferably also contain one or more electrolytes and may also contain a nonionic surfactant. The solutions provide ocular comfort and are particularly useful in patients that are experiencing mild to moderate dryness or other irritation of the cornea.  The solutions may be packaged as either an unpreserved unit dose product or as a preserved multi-dose product. The multi-dose products contain a very mild antimicrobial preservative system, and consequently can be frequently applied to the eye with little risk of ocular irritation attributable to the preservative components.
