摘要： Cathodes having abnormal electrical conditions associated therewith in an electrolytic copper refinery tankhouse are rapidly and positively identified to enable the early remedying of the abnormal condition or conditions, for instance short circuited cathodes or poor contacts, by closing the normallyopen, cathode bar receptive, pivotally mounted, automatically closeable and automatically openable jaws of a sensing head of an electrical current measuring instrument, or of the sensing heads of a plurality of current measuring instrument units depending from a common supporting means of a current measuring apparatus, about one or more of a plurality of spaced apart cathode bars in the tankhouse and from which the cathodes are suspended and immersed in the electrolyte. The sensing head jaws are closed about the cathode bars by lowering the instrument or apparatus whereby shoes of the instrument''s operating mechanism are forcefully applied against the cathode bar or bars due to the weight of instrument or apparatus parts, thereby automatically closing the jaws of the sensing head or heads to substantially encompass the cathode bar or bars. The current passing through each cathode bar is measured by utilizing the magnetic field created by the current passing through the cathode bar to induce a measurable e.m.f. and a measurable electrical current in conductive coils on non-magnetic cores of the sensing head jaws in a preferred embodiment. The current measurement value for the cathode bar or each of the cathode bars is compared with a predetermined desired current measurement value for its suspended cathode thereby positively identifying any cathode or cathodes having an abnormal electrical condition or conditions associated therewith.

摘要： A recirculatory system for granulating molten slag comprising water jet nozzle granulators and a receptacle which contains a settling separation section wherein the coarse slag particles are separated from the water of elevated temperature containing fine slag particles suspended therein. The fine slag particles are removed from the water by use of one or more hydrocyclones. Conduits conduct the fine slag particle-free water of elevated temperature from the hydrocyclones to a cooling tower which cools the water. Conduits then conduct the cool water back to the jet nozzles.

摘要： System for the gastight sealing off and isolating of a section or sections of a flue system, wherein a damper is movable in a guide frame secured to the flue between an open position and a closed position wherein the damper nongastightly closes off a section of the flue. A pressurizable chamber is defined within the damper and extends about at least an outer marginal portion of the damper, with at least that portion of one or both chamber sidewalls adjacent a seating surface of the frame and an edge of the flue adjacent the frame seating surface (when the damper is in the closed position) being yieldable. The introduction of fluid under pressure into the pressurizable chamber when the damper is in the closed position pressurizes the chamber and forces the yieldable sidewall portion or portions into a gastight sealing relationship with at least one of a seating surface of the frame and an edge of the flue adjacent the frame, thereby sealing off and isolating a section or sections of the flue. Consequently workmen may safely perform maintenance and/or repair work on the isolated section of the flue on the downstream side of the damper.
