摘要： A method of tracking and reporting the velocity of a hand-held paint spray gun. The object to be painted is placed in a room having one or more fiducial walls. A camera is installed on the spray gun, with its field of view toward the one or more fiducial walls. As the object is painted, the camera detects fiducials, calculates their current position, and compares current positions to previous locations to determine movement and velocity. The current velocity is compared to a stored target velocity, and audible or visible feedback is provided to the spray gun operator.

摘要： A process for the extraction of a metal from an ore or concentrate comprises subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic solution containing halogen ions and a source of bisulphate or sulphate ions, such as H.sub.2 SO.sub.4. The metals which can be extracted by the process comprises copper as well as non-cuprous metals such as zinc, nickel and cobalt. During pressure oxidation the metal may be precipitated as an insoluble basic salt, such as basic copper sulphate, or substantially completely solubilized and precipitated later as the basic metal salt.

摘要： Copper arsenate, substantially free from impurities that form sludge in wood preservatives such as chromated copper arsenate, is prepared by adding a solution of soluble arsenate to copper sulfate solution, either or both solutions containing sludge-forming impurities, to form a copper and arsenic-containing solution without precipitating copper arsenate. The pH during the adding is controlled at a value in the range of 1.8 to 2.2 to precipitate impurities. Precipitated impurities are removed, and the copper and arsenic-containing solution is neutralized with a suitable alkaline substance to pH 3.5 to 5.0 to precipitate copper arsenate. Arsenate solution is derived from arsenic oxides, soluble arsenic salts and compounds and metallurgical materials capable of yielding water-soluble arsenate. Copper sulfate solution is derived from crystals and compounds and metallurgical materials cable of yielding copper sulfate. In a preferred embodiment, sodium arsenate is derived by aqueous caustic oxidative pressure leaching of flue dusts and copper sulfate is derived by aqueous acid oxidative pressure leaching of copper matte.

摘要： A method of tracking and reporting the velocity of a hand-held paint spray gun. The object to be painted is placed in a room having one or more fiducial walls. A camera is installed on the spray gun, with its field of view toward the one or more fiducial walls. As the object is painted, the camera detects fiducials, calculates their current position, and compares current positions to previous locations to determine movement and velocity. The current velocity is compared to a stored target velocity, and audible or visible feedback is provided to the spray gun operator.
