Abstract: The present invention provides a self-expanding stent for insertion into an artery or other internal vessel. The stent is formed from a series of radial bands each formed with overlapping first and second ends. The overlap between the first and second ends is variable, allowing each band to move between a contracted configuration and an expanded configuration. The first and second ends of each band are both formed to include a tab which is folded to hold the first and second end against the band.  The bands are distributed along a common axis to form a cylinder and interconnected by a pair of elongated strips. In use, the stent is placed over a balloon catheter and compressed to adopt the contracted configuration. The balloon catheter and stent are then advanced through a placement catheter and  to  a  target  site  where  the  balloon  is  partially inflated to free the stent for self-expansion. The balloon may then be more fully inflated to further expand any of the radial bands in the stent. The balloon is then deflated and removed,  leaving the expanded stent to support that target site.

Abstract: A process for the extraction of copper from a sulphide copper ore or concentrate comprises subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic chloride solution to obtain a resulting pressure oxidation filtrate and an insoluble basic copper sulphate salt. The pressure oxidation is conducted in the presence of a source of bisulphate or sulphate ions, such as sulphuric acid. The amount of the sulphate source added contains at least the stoichiometric amount of sulphate ions required to produce the basic copper sulphate salt less the amount of sulphate generated in situ in the pressure oxidation. In a particular embodiment, the pressure oxidation is carried out at a predetermined H+/Cu ratio so that the pressure oxidation filtrate contains a major portion of the copper in the ore or concentrate and the basic copper salt contains a minor portion of the copper in the concentrate. The invention further provides for the selection of the H+/Cu ratio according to the grade of the ore or concentrate, the value of the ratio being selected with increasing magnitude compared with decreasing grade of the ore or concentrate. In a further embodiment, the basic copper salt is dissolved in a subsequent atmospheric leaching stage. A concentrate copper solution, which is suitable for electrowinning, is obtained by means of solvent extraction. The process also provides for the extraction of zinc and nickel from the ore.

Abstract: Disclosed herein is a film/nonwoven laminate which incorporates a low gauge machine direction oriented film layer laminated to a nonwoven support layer. The individual layers are designed such that the film layer, in the laminated state, has an elongation at break value in the cross machine direction that is greater the elongation at peak load value for the nonwoven layer in the same direction. Consequently, if the laminate is subjected to severe stretching forces in the cross machine direction, the nonwoven layer will fail before the film layer. In addition, the laminate preferably has a peak load value of at least 300 grams. As a result, the laminate is particularly useful as, for example, an outercover material for personal care absorbent articles or as a portion of an article of clothing, or as a portion of a surgical drape, or as a portion of a surgical gown.
