Patent CA-2311978-A1 (CA)
Inventor: STEELE SONYA M
IPC: C11D7/26
Filed: 2000-06-19
Abstract: A controlled release bleach thickening composition comprising bleach, water, and 0.1 to 50 weight percent, based on the total weight of the controlled release bleach thickening composition, of at least one crosslinked carboxylated polymer which is prepared from 30 to 80 weight percent of at least one ethylenically unsaturated hydrophilic monomer, from 20 to 70 weight percent of at least one ethylenically unsaturated hydrophobic monomer, and from about 0.5 to about 10 weight percent of a degradable crosslinking monomer selected from the group consisting of a crosslinking monomer having at least two ethylenically unsaturated moieties, a crosslinking monomer having at least one ethylenically unsaturated moiety and at least one functional group capable of reacting with another functional group on a monomer to form a degradable crosslink, and combinations thereof. In the controlled release bleach thickening compositions, the solubility of the polymer is suppressed by crosslinking. Most of the polymer is isolated from degradation by the bleach, thus preventing degradation of the polymer backbone which destroys the thickening effect. Slow, but selective degradation of the polymer crosslinks acts to solubilize a small amount of polymer which functions as an efficient thickener. A continuous supply of the soluble polymer is established by this time release mechanism to replenish the soluble polymer as it is degraded by the bleach, thus maintaining the thickening effect after aging at elevated temperature.

Title: Divalent cation-containing well drilling and servicing fluid
Inventor: TRESCO KIM O
IPC: E21B43/25
Filed: 2000-08-01
Abstract: The invention provides clay-free, preferably biopolymer free, well drilling and servicing fluids comprising an aqueous divalent cation-containing water soluble salt, a bridging agent, and a pre-gelatinized crosslinked amylopectin starch suspending agent and fluid loss control additive. The concentration of the starch derivative is sufficient to provide the fluid with the following charactersitics: (a) a low shear rate viscosity less than about 10,000 centipoise; (b) a high shear rate viscosity at 511 sec -1 in the range from about 15 to about 70 centipoise measured at 120°F; (c) a fluid loss less than about 10 milliliters as measured at 185°F and 250 psi differential pressure across a 5 micron disk for 30 minutes; and (d) anti-settling characteristics as exhibited upon static aging the fluid for 16 hours at 185°F. The low shear rate viscosity of the fluids can be increased without increasing the high shear rate viscosity above about 70 centipoise by incorporating magnesium oxide and/or dipotassium hydrogen phosphate in the fluids. The invention also provides a method of making the clay-free well drilling and servicing fluid and a process of drilling, completing, and working over a well with the clay-free fluid.

Abstract: A system (100) and method for expediting the repair of a locomotive (102) having sustained damage (104) as a result of a collision. A library of as-built parts information (114) is manipulated to define a plurality of repair kits (110) each containing all of the parts necessary to repair the damage expected from a predefined collision event. A particular repair kit may be selected by a user in response to an actual collision to obtain a listing of the parts (308), a cost estimate (318) and a delivery forecast (320). All of the necessary parts may then be ordered as a unit and delivered to a repair location (106) in a single shipment, thereby minimizing the chance of missing or misplaced parts. The system may be accessed via an information network, and the selection of specific repair kit may be facilitated by the use of a graphical user interface to point-and-click on the. damaged regions of the locomotive.
