Patent CA-2316142-A1 (CA)
Inventor: CARCAGNO GABRIEL
IPC: F16L15/00
Filed: 2000-08-16
Abstract: A threaded union highly resistant to overtorque and compression that includes a threaded member in its internal surface -- called female -- that joins a threaded member in its external surface -- called male --. The union between the male extreme and the female is produced through the threaded surface. When the members are fully assembled, one axially oriented surface in the free extreme of one of the members -- called nose -- presses against a corresponding surface in the other member -- called shoulder of torque. This shoulder is comprised of two surfaces, a first one coincidentally oriented to the corresponding nose of the first member, and a second one truncated and conical in shape with an angle B and with the axis of the pipe located between the first surface and the internal cylindrical surface of the female member. This geometry increases the resistance of same to overtorque action, without having to increment the net contact surface between the annular surface axially directed of the nose and the corresponding surface of the shoulder of the second member.

Abstract: Copper values are efficiently recovered from a copper ore, including secondary sulfides, by first crushing the ore to a particle size P-80 of about 1 to 2 inches, then grinding the so crushed ore to a particle size P-80 of between Tyler 4 mesh and 20 mesh, and then classifying the ground ore into a fines fraction of less than 65 mesh and one or more coarse fractions of more than 65 mesh. The fines are then leached or subjected to flotation to form a concentrate which is leached to form a pregnant leach solution. In parallel, the coarse fraction or fractions are leached also to form a pregnant leach solution. The leaching operations are carried out with ferric sulfate lixiviant at atmospheric pressure and elevated temperature. During leaching ferric sulfate is reduced to ferrous sulfate. The pregnant leach solutions are then subjected to solvent extraction to recover the copper values and subsequently to electrowinning to produce copper metal. During the solvent extraction operation, free sulfuric acid is produced and is then used together with oxygen to oxidize the ferrous sulfate produced during the leaching steps back to ferric sulfate with is then re-used in the leaching of the fines and coarse fractions.

Title: Method, implant and delivery system for enhancing blood flow in tissue
Inventor: PARKER THEODORE L
IPC: A61F2/00
Filed: 1999-06-21
Abstract: This invention is a method, implant, and delivery system for enhancing blood flow in tissue, wherein an implant (21) is non-ablatively introduced into the tissue in order to stimulate production of angiogenic agents by the tissue.  The agents produced by the tissue are absorbed into the implant (21), where they are stored, and the stored agents are released back into the tissue when the production of agents by the tissue subsides. The implant (21) is fabricated of a bio-resorbing material which is resorbed onto the tissue after the agents are released, and is formed in a shape which resists migration within the tissue. The system for inserting the implant into the tissue includes a housing (38), a delivery head (27) which carries the implant, which is movable between extended, retracted positions relative to the housing (38), and actuator (28) mounted in the housing, and a depth gauge (56) mounted to the housing (38).

Title: Hemostatic agent, method and carrier for applying a blood clotting agent
Inventor: THOMPSON JOHN A
IPC: A61K33/00
Filed: 2001-04-30
Abstract: A hemostatic agent, method and carrier for arresting the flow of blood and other protein containing body fluids flowing from an open wound and for promoting wound healing. A broad aspect is directed to a substantially anhydrous admixture of an oxyacid salt and a hydrophilic proton donor which will hydrate in the presence of blood and body fluid to produce cations to promote blood clotting. The preferred oxyacid salts are alkali and alkaline earth salts of transition metals and halogen oxyacids with oxidizing capabilities sufficient to accelerate blood clotting. Another embodiment of the invention includes the compound containing an oxysalt plus a hydrophilic polymer such as carboxy methylcellulose, polyvinyl, alcohol, an alginate, and all soluble gums. Still another embodiment of the invention includes the compound formed of an oxyacid salt in combination with a hydrophilic proton donor and a solid desiccant which further accelerates blood coagulation reaction rates. The cation exchange material or an admixture of an alkali metal oxyacid salt plus acidic inorganic salt produces a scab or protective coating over the wound for protection and enhanced healing. Oxygen produced during the reaction substantially reduces the level of bacteria, virus and fungus at the wound. The resin is performance-enhanced for greater fluid uptake and more rapid coagulation.

Title: Self-optimizing device for controlling a heating system
Inventor: GILVAR DAVID L
IPC: G05D23/19
Filed: 2001-05-18
Abstract: A self optimizing device for controlling a heating unit in a manner so as to improve the energy efficiency of the heating unit using an autocalibration processor. The heating unit employs a heating medium that is heated by the heating unit and which transfers the heat into an ambient atmosphere outside of the heating unit. The heating unit has an on-state initiated when a characteristic of the heating medium representative of the heating capacity of the medium decreases below a minimum level, and an off-state initiated when the characteristic of the heating medium reaches a maximum level. The controller includes an input element, an output element, a time-measuring element, and a processor. The input element receives a signal from a sensor, the signal indicating the heating medium characteristic representative of the heating capacity of the heating medium. The output element signals the heating unit to begin its on- state. The time-measuring element measures an off-time, the off-time being the length of time from initiation of the off-state of the heating unit until the characteristic of the heating medium decreases below the minimum level. The processor determines a delay time and for signaling the heating unit to delay initiation of the on-state by the delay time amount, the extension of the off-time resulting in an energy savings over an undelayed initiation. The processor further comprising an autocalibration processor for determining a delay time that results in optimum energy savings.
