Abstract: Method and apparatus for separating iron or steel from slag by inductively pumping the iron or steel up an inclined trough away from the non-pumped slag.

Abstract: A ratcheting screwdriver is provided having an integral handle, shank and blade with a receiver body intermediate the handle and blade removably receiving a ratchet drive handle.

Abstract: The masonary or refractory material employed in the lining of blast furnaces has to be demolished, torn out, reconditioned, or replaced periodically, due to wear and deterioration of such material and the subject invention involves improved equipment or apparatus with respect to removing or delining this material.

Abstract: An improved metal-clad gas-type high-power circuit-breaker construction is provided involving two upstanding circuit-breaker assemblages electrically interconnected adjacent their upper ends, and connected into the series line transmission circuit, preferably, adjacent the mid-portions thereof to pressurized laterally-extending power-transmission lines.Improved structure is provided for simultaneously supporting the interrupting modules, or units up in the air interiorly of an outer grounded metallic casing structure, and, additionally, providing a high-pressure gas-conduit path to the pressurized insulating casing structure surrounding the circuit-breaker modules, and spaced inwardly from the outer grounded metallic casing structure.Improved means are provided for increasing the electrical power capable of being interrupted by such a structure, when desired, involving a series closing resistance, which is inserted into the circuit only during the closing operation of the interrupter.

Abstract: An improved high-voltage circuit-interrupter is provided having series main contacts and resistance contacts with a closing resistance shunting the resistance contacts, so that the closing resistance is inserted into the circuit during the closing operation of the high-voltage circuit-interrupter, but is out of the circuit during the opening operation. An improved latching mechanism is provided for ensuring that the resistance contacts remain closed, during the beginning of the opening operation of the breaker, so that the closing resistance is shorted out, and the task of extinguishing the established arc, or arcs is imposed only upon the main contacts and not at the resistance contacts.

Abstract: A carrier with a connector secured between terminals for enclosing spaced rtions of an object for support thereof, a link disposed for removable engagement with intermediate points of the connector to form a loop therein and limit the support portions of the connector, means for securing the loop to the link and to the support portions.
