Patent EP-0128887-B1 (EP)
IPC: C22B15/00
Filed: 1984-06-05
Granted: 1987-09-23
Abstract: The invention relates to a method for preparing a sui- phidic concentrate which is intended for further processing to copper and/or precious metals and which contains high percentages of arsenic and/or antimony, and possibly also bismuth in quantities likely to disturb subsequent processing stages, by partially roasting the concentrate in a fluidized bed, so as to eliminate substantially all the arsenic present and a major part of the antimony and/or bismuth. According to the invention, the concentrate and gas are supplied to a fluidized-bed reactor, and are there heated to a minimum temperature above the splitting or decomposition temperatures of the complex minerals containing arsenic and/or antimony and bismuth present in the concentrate. The oxygen potential in the reactor is regulated, so as to prevent the formation of non-volatile compounds of said impurities. The residence time of the concentrate in the reactor is controlled in a manner to ensure a given minimum elimination of the impurities. The gas and solids are withdrawn from the reactor and passed to a separating means, in which substantially impurity-free solids can be separated from the gas. The aforesaid minimum temperature and said regulated oxygen potential are maintained while the solids are in contact with said gas, and at least a part of the separated solids is returned to the reactor, for controlling the residence time, and an end product is removed from the fluidized bed and/or the separating means. The method is suitably carried out in one stage in a fluidized-bed reactor having a circulatory fluidized bed, although in certain cases the method can be carried out in two stages, in mutually separate reactors.

Abstract: Steel concrete-reinforcing rod is manufactured on a high speed rod rolling mill including a finisher followed by a cooling device for superficial quenching. The traction applied to the product leaving the finisher and approaching the cooling device is arranged to be appropriate to the correct advancement of the rod, by increasing the drive force of the rod and/or reducing the braking forces produced in the cooling device. Braking force in the cooling device can be reduced by introducing air into the cooling water.

Abstract: Système de conversion de puissance permettant d'effectuer une conversion entre une puissance électrique et une puissance motrice, pouvant être utilisé soit en mode générateur pour produire une puissance électrique à partir d'une puissance motrice fournie par un moteur premier (24) ou en un mode démarreur où la puisssance motrice est développée par le système de conversion de puissance à partir d'une puissance électrique et est appliquée par l'intermédiaire d'un convertisseur de couple (22) au moteur premier (21) pour le mettre en marche. Le système de conversion de puissance comprend un générateur principal (20), un excitateur (30) et un générateur à aimant permanent ou PMG (32), qui comprennent ensemble un alternateur sans balais (33). Lors du fonctionnement en mode démarreur, la puissance électrique est appliquée au PMG (32) pour qu'il fasse office de moteur et entraîne un rotor (29) commun au PMG (32), l'excitateur (30) et le générateur principal (20). Lorsque l'on a atteint une condition prédéterminée de fonctionnement du générateur (20), le générateur principal (20) est alimenté en puissance électrique provenant d'une régulation de moteur (56) pour que le générateur (20) se comporte comme un moteur synchrone et l'alimentation du PMG (32) est déconnectée. On commande ensuite le convertisseur de couple (22) pour transférer la puissance motrice du générateur (20) au moteur premier (24) pour mettre en marche ce dernier.

Abstract: This invention provides organopolysiloxane materials having cone penetration between about 100 and about 350 (10- <sup>1</sup>mm) and ultimate elongation of at least 100% and having reduced surface tack. This invention provides three methods of obtaining said materials with reduced surface tack. The first method comprises applying to the surface of such material an organic peroxide or a photoinitiator and irradiating the surface with ultraviolet light to further crosslink the surface to reduce or eliminate the tack of the surface. The second method comprises mixing a photoinitiator, such as benzophenone, in an organopolysiloxane fluid, thermally crosslinking the organopolysiloxane fluid to produce the material with the above cone penetration and ultimate elongation then irradiating the surface of the material with ultraviolet light to reduce or eliminate the tack of the surface. The third method comprises mixing a photoinitiator, such as benzophenone, in an organopolysiloxane fluid, crosslinking the fluid by irradiating a layer of the fluid with ultraviolet light to produce the above cone penetration and ultimate elongation properties then further irradiating the crosslinked material to reduce or eliminate the surface tack; this method can be carried out by simultaneous irradiation with ultraviolet light from two sides of a layer of the organopolysiloxane wherein one surface is irradiated at a higher intensity than the other surface. The materials produced by this invention are useful as tapes and sealants.

Abstract: The method provides a means for a dentist to record the shape in situ of teeth prepared for repair. During a search mode, a high resolution grey scale image is presented on a monitor. The scan head is positioned over the prepared cavity, using this visual feedback. A trigger initiates actual 3D data acquisition, which is accomplished in a fraction of a second using an active triangulation principle. The result is stored in congruent memory banks in the form of a 3D profile and a pseudoplastic grey scale image representing the back-scattered contrast. The pseudoplastic contrast image is displayed instantaneously on the monitor. The point to point relationship between the pseudoplastic grey scale image and the 3D profile allows use of the grey scale display as a drawing plane for operator data verification and editing. The contour lines defining the desired restorative implant appear as an overlay to the grey scale image, while the actual positional values of points on the contour lines are stored in and retrieved from the 3D profile. The contrast-derived pseudoplastic image not only provides higher intelligibility for the operator; but data processing algorithms can also make use for each image point of both sets of data, that is the 3D profile and the contrast image.

Granted: 1989-01-11
Abstract: A pressure plate for a mine comprises a hydraulic circuit. The mine is triggered by complete depression of the pressure plate. The hydraulic circuit comprises a pressure chamber containing a fluid that is compressed by a force applied to the pressure plate. The fluid is evacuated from the pressure chamber in a controled manner through a depressurization unit in response to a sustained force greater than a predetermined threshold being applied to the pressure plate. A bistable member moves between a first position in which it prevents communication between the pressure chamber and the depressurization unit and a second position in which it establishes communication between the pressure chamber and the depressurization unit. The bistable member is initially in the first position when no force is exerted on the pressure plate. It remains in the first position so long as the pressure plate is subjected to an increasing or stable force. It switches to the second position when the pressure of the fluid decreases after it has increased due to a force of this kind. Thus, after increasing to a maximum value and then decreasing to a minimum value, any increase in the force results in depressurization of the fluid and complete depression of the pressure plate. This explodes the mine.

Abstract: The yarn (1) is wound onto a cross-wound package (4) by means of a grooved drum (3), and a first sensor (6) is provided for determining the circumferential speed of a member rotating synchronously at the speed of the traversing yarn. A second sensor (7) determines the position of the yarn (1) on the package (4) in relation to the longitudinal axis thereof, and a correction factor is derived from this determination in order to determine the instantaneous yarn speed from the mean yarn speed obtained from the circumferential speed of the rotating member. 
<??>This improves the determination of the yarn speed in textile machines to such an extent that on-line spectrograms can be measured on the latter. Moreover, the accuracy with which the length of the yarn defects is measured is also increased by an order of magnitude.
