Title: Method and apparatus for heating drilling and/or completion fluids entering or leaving a well bore during oil and gas exploration and production
Inventor: LOPEZ PERRY A
IPC: E21B36/00
Filed: 2004-08-23
Granted: 2012-07-17
Abstract: A system for heating drilling, completion, and/or stimulation fluids including acidizing liquids but not limited to; entering or exiting a wellbore, the system including a principal heat exchange vessel; a first inlet for introducing heat transfer media into fluid flow lines within the vessel; an outlet for flowing the heat transfer media from the vessel; a second inlet for introducing fluids returning from or returning to the well bore for receiving heat from the heating fluid within the fluid flow lines in the vessel; an outlet for flowing the heated downhole fluids from the vessel to be returned down the borehole; a heater for heating the heating fluid to a desired temperature before returning the heating fluid to the heat exchange vessel.  Optimally, the drilling or completion fluid would be heated to 50 to 60 F (10 to 160C) above ambient temperature.

Title: Sodium chloride solution for drug reconstitution or dilution
Inventor: WEBB CHANDRA A
IPC: A61K38/48
Filed: 2006-10-27
Granted: 2011-11-29
Abstract: The invention provides methods for preparing pharmaceutical formulations for injection such that upon injection the formulation does not cause erythrocyte agglutination, hemolysis, and/or cell shrinkage. To prevent agglutination, a pharmaceutical formulation ready for injection needs to have a sufficient ionic strength. To prevent hemolysis or cell shrinkage, a pharmaceutical formulation ready for injection needs to be about isotonic with respect to plasma. The invention provides methods that prepare pharmaceutical formulations for injection that have both the sufficient ionic strength to prevent agglutination and the requisite tonicity to prevent significant hemolysis or cell dehydration or shrinkage. The present methods involve the use of sodium chloride solutions that are about 25 mM to about 150 mM for reconstituting lyophilized cakes (or other non-liquid pharmaceutical formulations) into solution or for diluting pharmaceutical formulation solutions.

Abstract: L'invention concerne des techniques permettant à des parents d'établir une sécurité pour enfants "zone pour enfants" sur un DVR. Selon l'une des techniques, un DVR reçoit, d'un parent, des identités d'articles de contenu de DVD que les parents ne souhaitent pas que leurs enfants visualisent. Le DVR mappe les identités dans une zone pour enfants. Durant la lecture du DVR en mode zone pour enfants, le DVR empêche l'affichage de contenus de DVD associés à ces identités. Cependant, le DVR peut encore obtenir et stocker ces articles de contenu. Lorsque le DVR n'est pas réglé en mode zone pour enfants, il permet l'affichage d'articles de contenu associés à ces identités, y compris des articles de contenu que le DVR a stocké et obtenu lorsqu'il était réglé en mode zone pour enfants.

Abstract: An image-forming medium and methods for forming and imaging the medium are provided. The disclosed medium can be strongly colored under room illumination (or deliberate UV) and can be selectively discolored at an appropriate light wavelength to form an image. In one embodiment, the image-forming medium can include a substrate (e.g., a sheet of paper), a photochromic material incorporated with the substrate, and a photo-absorbing material incorporated with the photochromic material. Exemplary methods for using the image-forming medium to make a transient image can include first forming the image-forming medium by applying a coating solution containing photochromic material to the substrate or paper. The image-forming medium can have a medium color and can then be selectively exposed to a radiation through a mask to convert the photochromic material from a colored form to a colorless form and thus to form an image having a color contrast with its background.

Abstract: The invention relates to a method for processing pyritic copper sulphide concentrate, in which, in addition to copper, there is arsenic and gold bound to the sulphide minerals, or invisible gold.  In the method concentrate is leached into a chloride-containing solution. Raw material leaching is performed in conditions where the copper, iron and arsenic of the raw material dissolve, but the gold-containing material remains undissolved. The chloride solution obtained is routed to neutralisation, where the iron and arsenic in it are precipitated. The purified copper solution is routed to liquid- liquid extraction, in the stripping stage of which copper is transferred to a sulphate solution, which is routed to copper electrowinning. Gold is recovered from the leaching residue by some known method.
