Abstract: A reactor/transporter apparatus for coating particles by thermally decomposing at least one metal carbonyl into selected metal values and carbon monoxide with the metal values depositing on the particles. The reactor/transporter includes an upper end, a lower end and a source of transport fluid including the metal carbonyl. The transport fluid is supplied into the reactor/transporter for coating particles as they travel from the lower to the upper end. A separator is connected to the upper end of the reactor/transporter for separating the particles from the transport fluid. A downcomer is connected to the separator for collecting the particles. A heater heats the particles and a valve regulates the flow of particles into the reactor/transporter from the downcomer. In addition, the reactor/transporter has a purge vessel for removing coated particles.

Abstract: A technique for presenting and fixturing small items that are coated by vapor deposition techniques. The objects are caused to be moved within the plasma stream to effect full coverage. The coating, if titanium nitride, is gold colored and is, for example, useful for coinage applications.

Abstract: A low coefficient of expansion alloy is coated with a thermal barrier coating having a low coefficient of expansion compatible with the alloy. The alloy, preferably a 900 series iron-base alloy, includes an oxidation resistant intermediate bond coating and a zirconia containing thermal barrier. An article of manufacture made from this material could be utilized in heat engines where close tolerances are mandated.

Abstract: A bit basket mounted on a drilling rig for making and breaking drill string connections. A movable "Y"-like shaped cam is swivelly mounted within a body. Drill string components, such as drill bits and hammers, extend into the basket. The cam has an arcuate engaging face with two tip ends. The cam is thrown so as to engage and hold the component stationary. The connection is then made or broken by the requisite rotation of the drill string by the drilling rig.

Abstract: A process for reduction smelting of copper-, nickel- or cobalt-containing materials in which such a material, at least partly in oxidic form is heated or combusted in finely divided form in a neutral or oxidizing flame to provide superheated particles. The superheated particles are then distributed onto a thin layer of coke. The materials in the particles are reduced in the thin layer of coke to metals or mattes or, in the case of iron, to wustite which forms a discardable slag with flux. Reduced product and slag form separate molten layers underneath the thin coke layer. All heat necessary for reduction and melting of product and slag is provided directly by the flame both in sensible heat in the superheated particles and by radiation.

Abstract: A power cable hanger for a mine including a roof mounted rail, a carriage travelling on the rail, a plurality of open-sided hooks to support a cable spaced at intervals along the path of the rail, an arm on the carriage to pick up and place the cable on the hooks and to retrieve the cable from the hooks and cable means, independent of the power cable to cause the carriage to travel backwards and forwards on the rail.

Abstract: A method of producing a composite material from a mixture of copper and a low coefficient of thermal expansion nickel-iron alloy (Invar) powder is disclosed wherein advantageously at least part of the copper is deposited on the Invar powder prior to processing. Processing includes cold compacting to a green strip or other configuration, annealing in the temperature range of 550.degree.-750.degree. C. and working the annealed material at a temperature in that range to high density.

Abstract: A copper converting process starting with white metal or a mixture of white metal and metallic copper in which oxidizing gas contacts the molten copper mass either at or near the top surface of the molten mass while the mass is sparged with an inert gas from at or near the bottom of the mass and sparging is continued after contact with the oxidizing gas ceases.

Abstract: A pipe cutting tool especially adapted to cut the interior of in-the-hole (I-T-H) drill pipe to allow subsequent removal of the pipe above the cut. Due to blasting damage, long sections of I-T-H pipe, otherwise in good condition, cannot be removed because the damaged section prevents the removal of the entire drill string. The tool is adapted to receive power from an external source and includes a frame, a pivoted motor and cutter, and an actuator for pivoting the motor.

Abstract: A process for autogenously smelting copper sulfide ore concentrate directly to semi-blister copper in which a calcareous flux is charged directly to an autogenouse furnace along with concentrate and copper-containing coolant. Furnace products are semi-blister copper, calcareous slag and off-gas rich in sulfur dioxide.

Abstract: A process for autogenously smelting sulfidic copper material in the presence of a calcareous flux in which slag cleaning to provide metallic copper is employed. Such metallic copper provided by slag cleaning is usefully employed as a coolant in the autogenous smelting operation.

Abstract: A rock bolt system (10) including a mechanical rock bolt (12) having an interior channel (24) therein and a feeder attachment (14). An anchor may be affixed to the distal end of the rock bolt (12). An aperture (22) extends from the rock bolt (12). The feeder attachment (14), capable of being demountably affixed to the proximal end of the rock bolt (12), supplies hardenable material to the interior channel (24) where it courses through the interior of the rock bolt (12) and exits into the bore hole (16) through the aperture (22). A breather tube (38) extending from the feeder apparatus and into the interior channel (24) permits entrapped air to escape.

Abstract: Uranium is leached from water slurries of uranium ore by incorporating a mixture of sulfur dioxide and air therein to provide the oxidizing and acidifying requirements to accomplish leaching.

Abstract: An apparatus for continuously conveying ore and the like. A penetrator, rotatably disposed about a common coaxial horizontal axis shared by the forward section of a first conveyor, fluidizes a muck pile to continuously load material onto the first conveyor. Actuators for independently oscillating the penetrator and independently positioning the first conveyor are provided. An optional second conveyor may be employed to transport the material away from the first conveyor.

Abstract: Discloses the use of an invertable, double-cavity mould for use in casting anodes to be electro-processed.

Abstract: 1. An improved method for producing fine nickel powder having a substantially spherical form and size ranging from about 3 microns to about 7 microns, containing sulphur within a critical range of about 0.02% to about 0.

Abstract: A process for removing sulfur dioxide from industrial gas streams by scrubbing the gas with an aqueous slurry including 2CaO.Fe.sub.2 O.sub.3 (dicalcium ferrite). The 2CaO.Fe.sub.2 O.sub.3 is present in lime slags or flotation tailings derived from non-ferrous smelting operations.

Abstract: An apparatus and method for continuously conveying ore and the like. A penetrator, rotatably disposed about a common coaxial axis shared by the forward section of an endless conveyor, fluidizes a muck pile to continuously load material onto the conveyor. The conveyor, hinged approximately amidships, is mounted above a movable frame. Actuators for independently oscillating the penetrator is provided.

Abstract: A compact, easily disassembled, minimum headroom drilling unit is disclosed. The drill, especially useful for newly developed vertical retreat mining methods, drills at compound angles from the vertical and horizontal directions. Low headroom is achieved by the employment of a double acting hydraulic cylinder.

Abstract: A process in which ferric ion in water-soluble form is added to an effluent containing cyanide, arsenic and antimony and having a pH of about 5 to 9 and treating effluent with SO.sub.2 and oxygen in the presence of soluble copper to produce a treated effluent having very low contents of cyanide, arsenic and antimony.
