Patent CA-2188910-A1 (CA)
Inventor: SCHMIDT HARTMUT
IPC: G01F23/296
Filed: 1996-10-25
Abstract: Measuring the level in a container is done by means of a sensor fitted above the highest  level occurring and measuring the distance to the surface of the material in the container. An evaluation  circuit  computes  the  level  from  the  distance measured by the sensor and the empty distance.  The material volume is determined from the relationship between level and material volume  memorized  in  the  evaluation  circuit.  For calibrating a sensor in the case of an unknown empty distance, without having to completely empty the container, the on-going filling or emptying of the container is interrupted and the actual material volume is recorded.  Using the sensor to be calibrated a distance measurement is implemented and the actual material  volume  is  entered  in  the  evaluation circuit.  The evaluation circuit determines on the basis of the memorized relationship  between  level  and  material  volume  the  level belonging to the entered material volume and computes the empty distance as the sum from said level and the ranging result. In this way calibration is possible at a single calibration point without having to change the level in the container.

Title: Chloride assisted hydrometallurgical copper extraction
Inventor: JONES DAVID L
IPC: C22B3/06
Filed: 1994-12-20
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: La présente invention concerne un procédé d'identification d'échantillons de patients qui consiste à ajouter à un échantillon, de préférence lors du prélèvement de cet échantillon, une pluralité d'oligonucléotides d'identification. Ces oligonucléotides d'identtification sont co-traités et séquencés en même temps que l'échantillon. Le séquençage résultant permet ainsi d'obtenir à la fois la séquence de la région d'intérêt dans l'échantillon d'ADN, et la séquence des oligonucléotides d'identification qui servent à confirmer l'identité du patient. Selon un mode de réalisation de cette invention, on utilise une pluralité d'oligonucléotide d'identification spécialement construits. Chaque oligonucléotide d'identification est construit à partir d'un oligonucléotide de départ et il comporte (a) un site d'amorce qui n'est pas homologue de l'ADN de l'organisme sur lequel l'échantillon a été prélevé et qui peut être identique ou différent du site d'amorce des autres oligonucléotides d'identification (b) ainsi qu'une région d'identification (b) ainsi qu'une région d'identification représentée par la formule générale -(M-N)¿x?- ou -(M-N-N)¿x?- dans laquelle N représente un résidu de nucléotide qui est le même dans l'oligonucléotide d'identification et dans l'oligonucléotide de départ, M représente un résidu de nucléotide qui peut être identique à, ou différent de l'oligonucléotide de départ, à condition qu'au moins un résidu M dans la région d'identification soit différent de l'oligonucléotide de départ, et x est un entier compris entre 3 et 20. Pour être sûr qu'il n'y ait pas de recouvrement entre plusieurs jeux d'oligonucléotides d'identification, il est possible de construire les oligonucléotides d'identification de telle sorte que les régions d'identification de chaque jeu soient localisées à un emplacement différent le long de l'oligonucléotide de départ.
