Patent CA-2197065-A1 (CA)
Inventor: DESAI JAWAHAR M
IPC: A61B18/14
Filed: 1996-04-18
Abstract: A system and method for cardiac mapping and ablation include a multi-electrode catheter introduced percutaneously into a subject's heart and deployable adjacent to various endocardial sites. The electrodes are connectable to a mapping unit, an ablation power unit, a pacing unit, all of which are under computer control. Intracardiac electrogram signals emanated from a tachycardia site of origin are detectable by the electrodes. Their arrival times are processed to generate various visual maps to provide real-time guidance for steering the catheter to the tachycardia site of origin. In another aspect, the system also includes a physical imaging system which is capable of providing different imaged physical views of the catheter and the heart. These physical views are incorporated into the various visual maps to provide a more physical representation. Once the electrodes are on top of the tachycardia site of origin, electrical energy is supplied by the ablation power unit to effect ablation.

Abstract: Regenerated cellulose food packaging film, including fibrous food casings which has modified cling properties for packaging sausage products. The cellulosic food casings have a fibrous reinforcement impregnated with regenerated cellulose composition which contains from about 0.01 to 2.5 weight percent of admixture of a viscose solution and a food grade cationic resin adhering agent and from about 0.001 to 2.5 weight percent of a protein. The film is prepared by impregnating a tubular fiber reinforcement with a viscose composition containing the resin and protein. The impregnating composition is applied in a single step by injecting the resin and protein into the viscose solution before being extruded into the fibrous web. This assures both even distribution of the polymeric adhering agent and protein in the web, as well as maintenance of a constant level of polymer and protein being applied during the coating process. The degree of cling/adherence of the casing to meat contained in the film is more uniform over the entire circumference of the tubular casing and is almost moisture independent.

Abstract: ABSTRACT OF THE DISCLOSURE    Provided  is  a method  of  purifying  a crude  nickel sulfate  solution  to  give  pure  nickel  sulfate  through solvent extraction, in which the impurities such as cobalt, calcium, magnesium, iron, zinc, copper, sodium, ammonia and others to be in the crude solution are removed while,  if necessary, effectively recovering cobalt, and for which the amount of a neutralizer to be used is reduced and the cost of treating wastewater is also reduced.    The method comprises a first purifying step comprising an extraction step of adding an organic acid extractant to a crude nickel sulfate solution to thereby extract nickel into the extractant to give a nickel-loaded organic phase, followed by a scrubbing step of scrubbing the organic phase as obtained in the previous extraction step with a nickel-containing  scrub  solution  to  thereby remove  sodium  and ammonia from the organic phase; and a second purifying step of adding a crude nickel sulfate solution to the nickel-retaining organic phase as obtained in the previous first purifying step so as to exchange the nickel in the organic phase  with  the  impurities  except  sodium  and  ammonia existing in the crude nickel sulfate solution added in this step, thereby giving a purified nickel sulfate solution and an organic phase containing impurities; and optionally a third purifying step of recovering nickel from the organic the organic phase containing impurities as obtained in the second purifying step, and a step of recovering a valuable metal, cobalt from the organic phase containing impurities.
