ABSTRACT:
A power activated assembly is disclosed that provides rapid and simultaneous disconnection and reconnection of water cooled power connectors to and from an induction furnace of a melting assembly which is tiltable about the axis of its trunnion. The power activated assembly carries extensions that have respective female connectors on the end and which have flexible conductors connected for supplying electrical power and cooling water to the induction furnace. The housing is positioned concentric with the trunnion so as to allow its female connectors to mate with corresponding male connectors of the assembly when the housing is axially moved toward and along the trunnion axis in response to motion control means such as a power activated device. The male connectors are distributed on the assembly about and inside the circumference of the trunnion. In one embodiment, the male and female connectors have flow control means such as shut-off valves which allow the water to flow from the coolant supply source to the vacuum furnace when the connectors are engaged and terminates such flow when the connectors are disengaged. The power activated assembly of the present invention reduces the time needed to remove the crucible of the assembly or to exchange the introduction furnace of the assembly.
