Abstract:

A biopsy probe mechanism includes an elongate sample receiving member having a longitudinal axis and having a sample receiving notch. An elongate sample receiving member and a cutting cannula are movable relative to one another along a longitudinal axis between a first relative position and a second relative position. A first echogenic feature is established on the elongate sample receiving member and a second echogenic feature is established on the cutting cannula. The first echogenic feature is in longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the first relative position. The first echogenic feature is out of longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the second relative position.

Appl. No.:

6/402977

Inventors:

Charles H. Simpson - Scottsdale AZ

International Classification:

C01G 5309

US Classification:

423147

Abstract:

A hydrometallurgical process for extracting nickel from comminuted nickel-bearing minerals. The process includes the steps of contacting the comminuting nickel-bearing minerals in an extraction zone with an aqueous solution having a concentration of chloride ions, metal ions and sulfuric acid at an elevated temperature and continuing the contact to form an extraction mixture slurry, including a liquid component comprising an aqueous solution containing extracted nickel and iron from the comminuted minerals dissolved therein and a solid tailings component; and, separating the liquid and solid components of the extraction mixture slurry.

Appl. No.:

5/964742

Charles H. Simpson - Scottsdale AZ

International Classification:

C10L 910
C01B 1714

US Classification:

44 1SR

Abstract:

Raw coal containing sulfur impurities and water is ground in a vapor-tight extraction zone in contact with a combustible sulfur solvent at an elevated temperature. An extraction mixture slurry is formed which includes a liquid component comprising the solvent and sulfur impurities and a solid component comprising the comminuted, extracted coal. The liquid and solid components of the slurry are separated. At least a portion of the liquid component is preferably treated to separate sulfur. The liquid component is recycled to the extraction zone. If the solid slurry component has an undesirably high pyrite content, it is then reacted with a reagent to decompose the pyrites to water-soluble sulfur compounds and the reaction mixture is washed with water.

US Classification:

75101R

Abstract:

A process for removing precious metals from comminuted ores. The process comprises the steps of first contacting comminuted ore with a primary acidic hypochlorite solution, separating the ore from the primary hypochlorite solution and then contacting the separated ore with an aqueous hypochlorite solution having a pH greater than 7.

International Classification:

C10L 902
C10L 906

US Classification:

44 1SR

Abstract:

A process for removing sulfur and ash from coal and other carbonaceous materials involving treating an aqueous slurry of coal or other carbonaceous materials at an elevated temperature below the oxidation temperature of the coal or other carbonaceous materials in the presence of an oxidizing agent capable of reducing pyritic sulfides to a soluble state with: (A) an alkaline earth metal and/or alkali metal chloride, a catalyst comprising one or more deliquescent halogen compounds, barium chloride, potassium chloride or mixtures thereof, and one or more reducing oxides, chromate salts or mixtures thereof, and an inorganic acid, or (B) a formulation comprising one or more hypochlorites and the above-described catalyst or catalyst and acid. Sulfur is extracted as sulfate or other soluble sulfurs. In a second embodiment, elemental sulfur may be extracted intermediate to producing sulfate and other soluble sulfur by treating an aqueous slurry of the coal or other carbonaceous materials at an elevated temperature below the oxidation temperature of the coal or other carbonaceous materials with an alkaline earth metal and/or alkali metal chloride and nitric acid.

Abstract:

A biopsy probe mechanism and method includes an elongate sample receiving member having a longitudinal axis and having a sample receiving notch. The elongate sample receiving member and a cutting cannula are movable relative to one another along a longitudinal axis. A first echogenic feature and a third echogenic feature are established on the elongate sample receiving member and a second echogenic feature and a fourth echogenic feature are established on the cutting cannula. The elongate sample receiving member and the cutting cannula have a first position in which the first echogenic feature is in longitudinal alignment with the second echogenic feature, and in which the third echogenic feature is in longitudinal alignment with the fourth echogenic feature.
