Title: Recovery of metals from ore
Inventor: DUYVESTEYN WILLEM P C
IPC: C22B15/00
Filed: 2000-10-31
Granted: 2011-01-11
Abstract: A bio-leaching method is provided for recovering metal from a metal containing ore. The ore is subjected to contact with a microorganism selective to the oxidation of sulfur. A sulfur containing compound is mixed with the microorganism before, during or after contact with the ore to systemically form sulfuric acid to leach the metal from the ore. The ore is in the form of a slurry, a heap, a charge in a vat and is bioleached for a time sufficient to dissolve the metal in the ore and form a metal-rich leachate and an ore residue. The metal can then be extracted from the metal-rich leachate. The metal containing ore may contain base metals, precious metals, or platinum group metals. Upon formation of the metal-rich leachate, the ore residue may be further processed to recover any precious metals or platinum group metals that may be present.

Abstract: An adjustable curling aid is disclosed comprising two opposed side members for receiving a handle of a curling rock therebetween, adjustment means disposed between and connecting the side members for adjusting the distance between the side members to accommodate the girth of the handle, an end member connected and generally perpendicular to a side member for transmitting force to the handle, and engagement means pivotally connected to at least one side member for engaging with an elongate actuating means to exert force on the curling aid.  As the handles of curling rocks are not of standard girth, the present invention provides physically challenged curlers with a curling aid that can engage different sized handles while maintaining fine control of direction and rotation.

Title: Multidimensional addressing architecture for electronic devices
Inventor: LEISTAD GEIRR I
IPC: G09F9/30
Filed: 2001-03-22
Granted: 2005-06-28
Abstract: In a means for providing addressability in an apparatus comprising one or more volume elements which together with said means form part of a matrix in the apparatus and wherein a volume element comprises one or more cells with a data storage or processing functionality, said means establishes an electrical connection to specific cells by means of electrodes in the matrix and thereby defining a cell in the volume element. Said means comprises at least three sets of plural strip-like electrodes, the strip-like electrodes of each set being provided in substantially parallel relationship to each other in a two-dimensional planar layer forming an additional part of the matrix. A set of strip-like electrodes in a layer is oriented at an angle to the projected angle of orientation of the electrode sets in proximal neighbouring layers onto this layer, such that the sets of strip-like electrodes in proximal neighbouring layers exhibit a mutual non-orthogonal relationship. A selective addressing of a cell takes place applying current or voltage to selected electrodes in each electrode set. An apparatus comprising a means of this kind is realized by a stack of two or more matrices located on a substrate, thus implementing a volumetric device for data storage or data processing.

Abstract: Heparin reduces ischemia-reperfusion injury to myocardium. This effect has been attributed complement inhibition, but heparin also has other activities that might diminish ischemia-reperfusion. To further probe these mechanisms, we compared heparin and an O-desulfated nonanticoagulant heparin with greatly reduced anti-complement activity. Given at the time of coronary artery reperfusion in a canine model of myocardial infarction, both heparin and O-desulfated heparin equally reduced neutrophil adherence to ischemic-reperfused coronary artery endothelium, influx of neutrophils into ischemic-reperfused myocardium, myocardial necrosis and release of creatine kinase into plasma. Heparin and O-desulfated heparin also prevented dysfunction of endothelial-dependent coronary relaxation following ischemic injury. In addition, heparin and O-desulfated heparin inhibited translocation of the transcription factor NF-.KAPPA.B from cytoplasm to the nucleus in human endothelial cells and decreased NF-.KAPPA.B DNA binding in human endothelium and ischemic-reperfused rat myocardium. Thus, heparin and nonanticoagulant heparin decrease ischemia-reperfusion injury by disrupting multiple levels of the inflammatory cascade, including the novel observation that heparins inhibit activation of the pro-inflammatory transcription factor NF-.KAPPA.B.
