  • Publication number: 20050155458
    Abstract: The present invention is directed to a system for recovering metal values from metal-bearing materials. During a reactive process, a seeding agent is introduced to provide a nucleation site for the crystallization and/or growth of solid species which otherwise tend to passivate the reactive process or otherwise encapsulate the metal value, thereby reducing the amount of desired metal values partially or completely encapsulated by such material. The seeding agent may be generated in a number of ways, including the recycling of residue or the introduction of foreign substances. Systems embodying aspects of the present invention may be beneficial for recovering a variety of metals such as copper, gold, silver, nickel, cobalt, molybdenum, zinc, rhenium, uranium, rare earth metals, and platinum group metals from any metal-bearing material, such as ores and concentrates.

  • Publication number: 20050155459
    Abstract: The present invention relates generally to a process for the production of sulfuric acid and liberation of precious metal values from materials containing sulfur through pressure leaching operations. In accordance with various aspects of the present invention, the sulfur-bearing materials may comprise residues from pressure leaching operations, such as those carried out at medium temperatures. The process of the present invention can be advantageously used to convert such sulfur-bearing materials to sulfuric acid by means of pressure leaching. The sulfuric acid so produced can be used beneficially in other mineral processing operations, for example those at the site where it is produced. Metals, such as precious metals, that are contained within the sulfur-bearing materials advantageously may be recovered from processing products by established precious metals recovery technology.

  • Publication number: 20050109163
    Abstract: A system and process for recovering copper from a copper-containing ore, concentrate, or other copper-bearing material to produce high quality cathode copper from a leach solution without the use of copper solvent/solution extraction techniques or apparatus. A process for recovering copper from a copper-containing ore generally includes the steps of providing a feed stream containing comminuted copper-containing ore, concentrate, or other copper-bearing material, leaching the feed stream to yield a copper-containing solution, conditioning the copper-containing solution through one or more physical or chemical conditioning steps, and electrowinning copper directly from the copper-containing solution in multiple electrowinning stages, without subjecting the copper-containing solution to solvent/solution extraction prior to electrowinning.

  • Patent number: 6279371
    Abstract: A hand-held tool for forming a rivet head at the plain end of a rivet includes an elongated handle having an elongated internal cavity with a guide wall surface extending to an adjacent guide wall surface in an insert having an end wall. The end wall is provided with a predetermined thickness and contains an aperture to house a shop head formed on the plain head of a rivet. An inertia block is slidably guided by the guide wall surfaces of the handle and insert for reciprocation between a displaced position remote from the end wall and a position for contact with the end wall. A spring located in the elongated handle urges the inertia block against an end of a rivet when protruding from the aperture in the end wall and arrests recoiling movement of the inertia block after impact with a rivet end in a direction away from the end wall.

  • Patent number: 6183871
    Abstract: A sealing glass paste which comprises at least one sealing glass frit powder and an aqueous binder which comprises an aqueous solution, dispersion or emulsion of a polymeric material and a water soluble oxidant which decomposes at a temperature of below 475° C., the polymeric material burning out or decomposing at a temperature of below 475° C., in the presence of the oxidant, to leave less than 2% of residues based on the total weight of the solids content of the binder. The sealing glass pastes may be used in the assembly of cathode ray tubes. The aqueous binder system which is used results in low carbonaceous residue levels after firing and does not contain volatile organic solvents. Furthermore, using this aqueous binder system sealing glass pastes can be prepared with sealing glasses which include PbO therein.

  • Patent number: 5735346
    Abstract: The artificial lift control system utilizes a piggy back line, flow computer, pressure transmitter, and software control to control artificial lift of wellbore fluids. The piggy back line is a medium to high pressure line strapped to the outside of the tubing. Supply, make-up gas or other fluids are pumped down the piggy back line at the lowest flow rate possible. Extremely low flow rates are utilized to minimize friction of flow in the piggy back line. A pressure or differential pressure transmitter is installed to monitor pressure on the piggy back line or to measure the differential pressure between the piggy back line and the casing pressure. The flow computer monitors pressures or differential pressures, utilizes software instruction sets to calculate fluid levels in the casing tubing annulus, and cycles artificial lift on and off based on parameters set in the flow computer software.

  • Patent number: 5405755
    Abstract: A method and an apparatus is disclosed for detecting whether a catheter is the cause of an infection in a patient without removing the catheter from the patient. The apparatus includes a wire handle, brush and a protective, microbially impervious bag disposed over the handle and brush. In use, the apparatus is connected to a catheter, the brush is advanced through the catheter, and simultaneously removed from the protective bag. The apparatus is then withdrawn from the catheter, and simultaneously back into the bag, and the bag is capped to maintain the proper humidification of an fibrin sample obtained so that the microbes thus obtained remain viable.

  • Patent number: 4492048
    Abstract: A labeling keeper including a protective sheet. The sheet is releasably attached to a backing sheet by adhesive and scored so that individual protector strips may be removed from the backing sheet. The protector strips are wrapped around an attachment member which holds the article to be identified such as a key. The attachment member is formed with an arm which holds the article. The protector strip when wrapped about the attachment member latches the arm so that the article cannot separate from the attachment member.
