Abstract: A low pressure aluminum casting apparatus includes a pair of steel dies each presenting a molding surface and a heat transfer surface. Copper heat sink blocks are disposed on the heat transfer surfaces to remove heat from the steel dies. Steel contact plates and steel spacer plates can be disposed between the heat sink blocks and the steel dies to optimize cooling. In addition, a portion of each contact plate can be spaced from the steel die to reduce cooling. The steel dies include conventional cooling passages for conveying cooling fluid, and the heat sink blocks, contact plates, and spacer plates also include cooling channels for conveying cooling fluid.

Abstract: An easy-to-use workflow language can be created by extending an existing, common language such as JAVA. The language can be extended by adding those constructs that are missing but desirable. Such desirable constructs can include parallelism, asynchrony, loops over asynchronous events, and flexible handling of XML. Such constructs can allow a user to define a virtual program using the extended JAVA syntax. For example, XML can be placed inside a JAVA class that defines the high-level orchestration logic a workflow should follow. That orchestration logic can refer to the JAVA class to carry out work, such that the logic to handle an incoming message is really in JAVA. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
