Motor Drives & Controls, Inc. - Hatfiled PA

International Classification:

B66B 25/00

US Classification:

198323, 198325

Abstract:

A combplate closes the terminal ends of a continuous belt transport system having grooved carrier plates. The combplate has a plurality of protrusions and a communications board. The plurality of spaced apart projections are located along the one lateral edge with a portion thereof extending forward of the one lateral edge, shaped to align with and pass between the carrier plate grooves, and provided with a detector that senses a break in its integrity and a circuit for communicating its status externally. The communications board is in electrical contact with each of the projections for repeatedly monitoring the status of each projection to detect a break in a projection's integrity.

Abstract:

A system () and method () for unit cell casting of titanium or titanium-alloys is disclosed herein. The system () comprises an external chamber (), a crucible () positioned within the external chamber (), an induction coil () positioned around the crucible, an internal chamber () positioned within the external chamber (), and a mold () positioned within the internal chamber (). The external chamber () is evacuated and a pressurized gas is injected into the evacuated external chamber () to create a pressurized external chamber (). An ingot () is melted within the crucible utilizing induction heating generated by the induction coil (). The internal chamber () is evacuated to create an evacuated internal chamber (). The titanium alloy material of the ingot () is completely transferred into the mold () from the crucible () using a pressure differential created between the external chamber () and the internal chamber ().
