Abstract: Improved concrete or mortar materials wherein cement in the precursors for these is replaced by electric arc furnace dust in amounts from 0+% to 4% or more based on the amount of cement by weight. In addition, the electric arc furnace dust can be used as an additive to obtain the same effect.

Abstract: A tube connector utilized in connecting a drip tube to a header pipe in a heap leach mining percolation system which provides for strength at the normally weak connection between the header pipe and the drip tube. The tube connector includes a housing providing a fluid passageway extending therethrough between a header pipe and a drip tube. A nipple section is formed at one end of the housing for accommodating the drip tube therearound which is of a relatively short length, and hence, a relatively short bending movement, to significantly reduce breakage of the connector during transportation.

Abstract: An assembly for converting a conventional drill press into an oscillating spindle sander is disclosed. The oscillating spindle sander assembly is comprised of an auxiliary motor which is adapted to be mounted on a drill press. An eccentric drive is attached to the rotating shaft of the auxiliary motor and is used to drive a push rod in a lateral reciprocating motion. The opposite end of the push rod is attached to one of the spindle spokes of the drill press, and causes it to move in a radially reciprocating motion which induces the drill press spindle, drill chuck and a sanding tool mounted therein, to move up and down in an oscillating motion. The oscillating spindle sander assembly of the invention can be easily disabled and the converted drill press returned to normal operation by removing the push rod from the spindle spoke of the drill press.

Abstract: A carton loading system has a carton carrier movable along a carton carrier support track driven by a continuous conveyor. The continuous conveyor has a first path segment in which the continuous conveyor drives the carton carrier along the track while a carton is placed into the carton carrier from a carton storage magazine by a carton transfer device. The continuous conveyor also has a second segment with a first portion arranged such that the conveyor is disengaged from the carton carrier to allow the carrier to a stop, permitting loading of the carton. At the loading station an accumulator may be positioned to load the carton. The second portion of the second segment is such that conveyor re-engages the carton carrier so that the carton carrier moves again along the track. The carton may be discharged from the carton carrier while the carton carrier moves along the track. The system may be adapted to provide for adjustable components such that cartons of differing depths can be accommodated.

Abstract: A method for depositing continuous cohesive, non-granular tightly adhering deposits on a substrat by using a rotating fibrous transfer means; deposit starting material is a small particle materials such as diamond powder; or powders of complex materials such as superconducting materials such as of the Y--B--C--O type; discrete deposits may be made and thereafter built-up on the substrate.

Abstract: A sampling device for a batch or continuous pulp digester for reduction of pulp sampling errors such as during a digester "blow" and for improving a pulping process based on the obtained samples.

Abstract: A method for thread laying and a thread laying machine; thread laying has been achieved by a machine that has a vacuum table and above it a gantry with a thread dispensing device on a shuttle operating in an x- and y- direction; the gantry may be fixed to a pair of carriage on the x-axis driven in unison or each of the carriages may be independently driven; curved threads as well as threads on a mold may be laid down on a substrate; typical material produced is sail material of considerable thread pattern complexity; single threads or a multiple of threads may be laid down through one thread head with an adhesive properly coating the threads; multiple thread heads as well associated apparatus such as laser cutters and the like are mounted on the gantry.

Abstract: A centrifugal finisher having an outer vessel and at least one inner vessel includes a traction surface between the inner surface of the outer vessel and the outer surface of each inner vessel. The inner vessels revolve about the axis of the outer vessel, and rotate about their own internal axes. The traction surface permits the outer wall to restrain the inner vessels and simultaneously causes the rotation of the inner vessels through interaction with the outer vessel, which can be stationary or moving at a different rotational speed and/or at a different rotational direction than the part which revolves the inner vessels.

Abstract: Polyurethane polymers useful as hydrogels wherein the polyol is a specific polyol of block copolymers and a method for desalination of water.

Abstract: A hydrometallurgical process for the recovery of precious metal values from refractory precious metal ore materials containing preg-robbing carbon by leaching with a thiosulfate lixiviant, the process comprisinga. providing a body of particles and/or particulates of an ore material having precious metal values and preg-robbing carbonaceous components;b. contacting the body of particles and/or particulates with a thiosulfate lixiviant solution at conditions conducive to the formation of stable precious metal thiosulfate complexes;c. recovering the thiosulfate lixiviant from the body of particles and/or particulates after a period of contact which is sufficient for the lixiviant solution to become pregnant with precious metal values extracted from the ore material; andd. recovering the precious metal values from the lixiviant solution.In a preferred embodiment, the refractory ore materials are low grade precious metal ore materials.

Abstract: The invention relates to a method of production of ultradispersed diamond which can be used for the production of abrasive materials, more particularly, this method relates to production of fine diamond powder by explosive means.

Abstract: The invention relates to a method for preparing HMP terfenadine comprising the steps of reacting terfenadone free-base with sodium borohydride to yield mixed polymorph terfenadine and crystallizing said mixed polymorph terfenadine from a seeded ester or ketone solvent system to yield substantially pure HMP terfenadine.

Abstract: A hydrometallurgical process for the recovery of one or more metal values from a metal ore material in the presence of clays and/or fines material, said ore material being comprised of one or more metal values and a matrix material having a sulfur content wherein the sulfur is present in an oxidation-reduction state of zero or less. The process comprises forming particulates from particles of said ore material, particles comprising said clays and/or fines material, an acid-resistant polymeric agglomeration aid and an inoculate comprising bacteria capable of at least partially oxidizing the sulfur content; forming a heap of said particulates; biooxidizing the sulfur content and recovering those one or more metal values.

Abstract: A spinnaker wherein the head section of the spinnaker incorporates a novel panel and sub-panel layout which improves the control of the spinnaker in use and allows projection of a greater sail area.

Abstract: A centrifugal disk finisher includes a porous layer at the bottom of the vertical wall of the containment vessel. A pressurized fluid, preferably air, is forced through the porous layer so as to form a fluid bearing between the bottom of the porous layer and the spinning disk enclosed within the containment vessel. The containment vessel is levitated above the spinning disk by a small amount due to the presence of the fluid bearing, so that the disk spins without any contact with the containment vessel, thus reducing wear. The fluid bearing also acts as a seal, which repels particles from the interface between the disk and the porous layer due to the small height of the fluid bearing and its imperviousness to all but the most energetic particles.

Abstract: Acetonitrile is purified by treatment with ozone. After ozone treatment is ended, acetonitrile is passed through packed columns of molecular sieve, activated alumina and charcoal or graphitized carbon; the process results in virtually pure acetonitrile obtained at an efficiency unachievable by prior art processes.
