摘要： A molded case circuit breaker incorporates vacuum switches operated by a toggle mechanism. Pole arms tied together by a cross bar are rotated simultaneously by the toggle mechanism. A drive link translates the rotational movement of each pole arm into linear movement of a driven member along the axis of the movable electrode of the associated vacuum switch. A coupling bracket has a base section secured to the movable electrode, longitudinal sections straddling the movable electrode axis and terminal sections extending inward toward the plane of rotation of the pole arm from the ends of the longitudinal sections. Coupling members extend from the driven member through slots in the terminal sections of the coupling bracket. Springs couple the free ends of the coupling members to the coupling bracket to open and close the vacuum switch with operation of the toggle mechanism.

摘要： An apparatus, method and system for the casting of thin strips or strips of metal upon a moving chill block that includes an electromagnet located so that molten metal poured from a reservoir onto the chill block passes into the magnetic field produced by the electromagnet. The electromagnet produces a force on the molten metal on said chill block in the direction toward said chill block in order to enhance thermal contact between the molten metal and the chill block.
