20100084109	PROCESS AND APPARATUS FOR DIRECT CHILL CASTING - The present invention discloses an apparatus for direct chill casting of metal comprises an open ended mold cavity formed by a casting surface with an upper end and a lower end, a refractory sleeve located at the upper end of the mold cavity being adapted to receive molten metal, a coolant delivery system below the lower end of the mold for supplying coolant to chill the descending hot metal body, and a boron nitride ring mounted between the refractory sleeve and the peripheral wall of the mold cavity. In another embodiment, the apparatus for direct chill casting of metal further includes a downspout instead of a refractory sleeve that is located at the upper end of the mold cavity being adapted to receive molten metal having a flow control rod or a floating baffle where the flow control rod controls the amount of molten metal to enter the mold cavity. In a further embodiment, a process for the direct chill casting of a metal comprising the steps of continuously filling the upper end of the cavity with molten metal and permitting the molten metal to move downwardly through the mold to form an ingot, and simultaneously chilling the ingot by spraying coolant on the ingot from the coolant delivery system is provided.	04-08-2010

20090151555	Piston with a cooling gallery - A piston for an internal combustion engine is provided. The piston crown includes an interior surface that defines at least in part a cooling gallery and a cooling gallery surface within the piston. An annular surface may defines at least in part an annular passageway that allows fluid communication between an outer surface of the piston and the cooling gallery. Opposing annular surfaces may be abutted with a predetermined force, thereby limiting fluid flow from the cooling gallery to an outer surface of the piston. Further, an annular surface may extend into the cooling gallery to form a deflector along the cooling gallery surface, thereby limiting fluid flow from the cooling gallery to an outer surface of the piston.	06-18-2009

20110203547	PISTON AND CONNECTING ROD ASSEMBLY HAVING IMPROVED COOLING CHARACTERISTICS - A piston and connecting rod assembly wherein the piston includes an inner cooling gallery defined in the body thereof beneath the crown of the piston, an outer cooling gallery defined between the skirt of the piston and the body and beneath the crown. A pin bore is formed in the body. A connecting rod is adapted to interconnect the piston and crankshaft where the connecting rod has at least one end with a bore extending therethrough and adapted to be aligned with the pin bore of the piston. At least one end of the connecting rod is in fluid communication with the inner cooling gallery of the piston and includes a reservoir formed on the end of the connecting rod which is adapted to collect coolant therein.	08-25-2011
