摘要： The disclosure is directed to a rotary wall deslagger for cleaning boilers. In accordance with the invention, an extensible rack element is selectively, mechanically coupled to a rotatable lance tube of the rotary wall deslagger to move the lance tube between a working and non-working position. When the selective mechanical coupling between the rack and the lance tube is released, the rack is extensible relative to the lance tube to activate a cleaning fluid discharge means and a driving means to impart a rotary motion to the lance tube. In accordance with another feature of the invention, the selectively-operable, mechanical coupling is released after the lance tube has been moved to its working position and the cleaning fluid discharge means and the rotary drive means are activated by the rack element substantially simultaneously with one another so that the cleaning fluid reaches the discharge nozzle of the lance tube at full pressure as rotation of the lance tube begins.

摘要： A centrifugal pump for circulating fluids at high pressure comprises an impeller having an axis of rotation, a casing defining a pumping chamber, a nonmagnetic canister sealed at one end and extending away from the pumping chamber surrounding an extension of the impeller axis, and an impeller shaft journaled in the nonmagnetic canister. The shaft has mounted thereto circumferentially magnetized rare earth cobalt magnets. A drive magnet assembly comprising a sleeve is journaled about the nonmagnetic canister with circumferentially magnetized rare earth cobalt magnets mounted therein. Rotation of the sleeve results in synchronous rotation of the impeller and impeller shaft.

摘要： A high temperature and high pressure consistometer comprises a cylindrical pressure vessel having an integral bottom and a cover for said pressure vessel. A nonmagnetic canister extends downwardly from said bottom and is sealed therein. A driven magnet assembly is journaled in said canister. A drive shaft is connected to said driven magnet assembly extending into said vessel. A nonmagnetic canister extends upwardly from the cover and is sealed therein. A driving magnet assembly is journaled in said canister. A shaft connected to said driving magnet assembly extends downwardly into said vessel. A driven magnet assembly is mounted for rotation on the exterior of the downwardly extending canister and a driven magnet assembly is mounted for rotation on the exterior of the upwardly extending canister. A sample cup is connected to the upwardly extending drive shaft and a paddle is connected to the downwardly extending shaft. External the vessel is positioned an instrument for measuring the torque magnetically transferred from the shaft carrying the paddle to the driven magnet assembly. External the vessel is a motor for causing the driving magnet assembly to rotate at a constant speed to thereby drive the cup within the vessel at a constant speed.

摘要： A handle for a magnetically actuated valve which bears rotating and fixed indicia for reading the valve position. The rotating indicia is placed upon a jacket carrying drive magnets. The fixed indicia is placed upon a cap covering the exposed end of a nonmagnetic bonnet separating the drive and driven magnet assemblies. External stop means prevent rotation of the jacket relative to the cap and bonnet more than about 90.degree.. Internal stop means prevent the rotation of valve and driven magnets more than about 90.degree..
