Title: Method for removing zinc from sulphured concentrates
Inventor: VAN PUT JOHN W
IPC: C22B3/08
Filed: 1994-08-24
Abstract: A portion of the concentrates is roasted and a portion of the resulting calcine is subjected to a neutral leaching step. Another portion of the concentrates is directly leached in an acidic medium in the presence of oxygen and under atmospheric conditions together with at least a portion of the neutral leaching residue. The zinc- and iron-rich solution resulting from acid leaching is neutralised with another portion of the calcine, the iron is removed and the solution is reused in the neutral leaching step. The method enables a gradual increase in the capacity of an existing zinc plant in accordance with demand, while capital costs may advantageously be spread out over time.

Abstract: Procédé et appareil permettant de créer une forme d'onde composite. On crée cette forme d'onde composite en codant une pluralité de signaux d'information d'entrée numériques (201). Ladite pluralité de signaux d'information d'entrée numériques codés (231, 235, 237) sont transmis à un combineur numérique (105) par l'intermédiaire d'un support de communication (103). Ce combineur numérique (105) combine la pluralité de signaux d'information d'entrée numériques codés. Enfin, la forme du spectre du signal d'information combiné de manière numérique permet d'obtenir une forme d'onde composite (107). Ces principes de création de forme d'onde composite peuvent être appliqués aux sous-bandes vocales à codage numérique dans un système de codage de sous-bande ainsi que les informations de voie dans un émetteur de système de communication à accès multiple par différence de code à séquence directe (DS-AMDC).

Abstract: For recording or reproduction of information, the optical beam is moved relative to the recording medium (11) along the longitudinal direction of a certain track (14). When accessing another track, the relative movement of the light beam along the longitudinal direction of the track is decelerated, and during this deceleration, the light beam is started to move in the direction transverse to the tracks toward the desired track. Thus, it is not necessary to wait for such time when the relative movement of the light beam along the longitudinal direction of the track has been completely stopped, and hence the necessary accessing time can substantially be reduced. If control is made to cause a decelerating rate of the relative movement to decrease continuously gradually or stepwise from a relatively high decelerating rate to a relatively low rate and the light beam is caused to start relatively moving toward the desired track while the relative movement is at the relatively low decelerating rate, it is allowed to effectively suppress occurrence of unwanted mechanical vibration due to abrupt deceleration of the relative movement.

Abstract: This invention is a device and procedure for the correction of optical abnormalities in a human eye. It involves use of an inventive electrosurgical energy probe (200) with specific physical configurations (204). The process preferably utilizes a high frequency R electro-desiccation or ablation device. The procedure involves the initial step of forming at least one access site allowing access to the corneal volume behind the Bowman's layer. It preferably is placed in the anterior surface of the cornea through and ending posterior to the Bowman's layer of the eye. The electrosurgical probe is then introduced into the access site and, depending upon the visual abnormality to be corrected, the probe is activated to adjust the volume of the corneal stromal layers through ablation or desiccation. For instance, if the optical aberration to be alleviated is hyperopia, a circular corneal volume reduction taking place about the outer periphery of the corneal mass may be accomplished. In certain circumstances, Bowman's layer may be cut to allow the curvature of the cornea to change after the corneal volume adjustment. These relief cuts may be radial, circular, semicircular or any other form appropriate for the option adjustment needed.
