Title: Intermittent molten metal delivery
Inventor: WAGSTAFF ROBERT BRUCE
IPC: B22D7/00
Filed: 2014-03-11
Abstract: Automated processes that dynamically control rate of delivery of molten metal to a mold during a casting process. Such automated processes can use dynamic metal level variation, control pin pulses and / or oscillation during the mold fill and transient portion of the cast. It has been found that such pulses keep metal flowing in a manner that addresses problems, particularly at the beginning of an ingot cast, associated with metal meniscus contracting and pulling away from the mold on the short faces and corners.

Abstract: A mechanical fastener assembly 14 is provided for joining two or more workpieces 10, 12. The assembly includes a mechanical fastener 42 and a slotted collar 26a, 26b. The mechanical fastener has a shaft 40 received within aligned bores 18a, 18b, 24a, 24b of the workpieces, while the slotted collar surrounds at least a portion of the shaft and is also received within the aligned bores. Inserting and advancing the slotted collar into the aligned bores causes the slot 28 of the slotted collar to at least partially close, thereby causing an inner surface of the slotted collar to engage at least a portion of the shaft of the mechanical fastener and an outer surface of the slotted collar to engage at least a portion of the aligned bores of the two workpieces. Such a mechanical fastener assembly can effectively transform a bolted joint into a stronger shear joint.
