Sean Timothy O'Keeffe - Coto de Caza CA, US

Assignee:

Crucible Intellectual Property, LLC - Rancho Santa Margarita CA

International Classification:

B22D 18/06
B22D 17/22

US Classification:

164 61, 164253, 164347

Abstract:

Disclosed is a vacuum mold with at least a first plate and a second plate to mold materials (e. g. , amorphous alloys), and a method for manufacturing parts using the mold. An ejector mechanism, to eject molded material, is enclosed within an ejector box that is vacuum sealed relative to the plates. An ejector rod for moving the mechanism is also vacuum sealed via a seal in a vacuum feed through opening. Seals are provided between adjacent interfaces of the mold parts (plates and ejector box) to vacuum seal the mold. The mold is connected to at least one vacuum source that applies vacuum pressure thereto via a first vacuum port in a first direction. A second vacuum port may also be provided to apply pressure in a second direction. A vacuum release valve may be connected to the mold to release vacuum pressure applied to the mold.

International Classification:

F24J 2/46
F24J 2/52

US Classification:

126569

Abstract:

A solar power plant includes central receiver modules arranged in a regular pattern. Each central receiver module includes a tower, a central receiver mounted on the tower, and a heliostat array bounded by a polygon. The heliostat array includes heliostats with mirrors for reflecting sunlight to the central receiver. The heliostats are grouped in linear rows and each of the rows is parallel to another row. The locations of the heliostats are staggered between adjacent rows. The power plant also includes a power block for aggregating power from the central receivers and power conduits for transferring power from the central receivers to the power block.

US Classification:

1563099

Abstract:

Provided in one embodiment is a method of forming an interfacial layer or a seal, the method comprising: providing a composition that is at least partially amorphous, the composition having a glass transition temperature Tg and a crystallization temperature Tx; heating the composition to a first temperature that is below Tx; disposing the heated composition to form the interfacial layer or the seal; and cooling the interfacial layer or the seal to a second temperature that is below Tg.

US Classification:

148522, 164429, 148538, 148541

Abstract:

Embodiments herein relate to a method for forming a bulk solidifying amorphous alloy sheets have different surface finish including a “fire” polish surface like that of a float glass. In one embodiment, a first molten metal alloy is poured on a second molten metal of higher density in a float chamber to form a sheet of the first molten that floats on the second molten metal and cooled to form a bulk solidifying amorphous alloy sheet. In another embodiment, a molten metal is poured on a conveyor conveying the sheet of the first molten metal on a conveyor and cooled to form a bulk solidifying amorphous alloy sheet. The cooling rate such that a time-temperature profile during the cooling does not traverse through a region bounding a crystalline region of the metal alloy in a time-temperature-transformation (TTT) diagram.
