Abstract: A header for a heat exchanger orients the position of an inlet port at an angle offset from the position of the outlet port on the header body in order to simplify the plumbing of the header within a system. In one implementation of a header for a heat exchanger, the header forms a header cavity defined by an external wall and which is separated into an inlet chamber and an outlet chamber by a dividing wall. An inlet port is defined within the external wall and is in fluid communication with the inlet chamber. Similarly, an outlet port is defined within the external wall and is in fluid communication with the outlet chamber. The inlet port is oriented on the external wall at an offset angle with respect to a position of the outlet port.

Abstract: A puller head mold for receiving molten metal or alloy during the casting of an ingot, the puller head mold having a tapered screw thread structure. The tapered threaded puller head is used to pull and withdraw a cast ingot from a casting furnace, and can be particularly useful for the handling of ingots having a relatively narrow diameter. The tapered threaded puller head profile provides for full release of the tapered threaded puller head from a cast ingot in a fraction of a turn. The size and profile of the cast ingot formed with the tapered threaded puller head is resilient to thermal gradients while cooling.

Abstract: A method for synchronization of user terminal (UT) uplink data transmissions to a satellite in a satellite communications system is provided. The UT tracks frame timing and frequency of downlink data transmissions received by the UT from the satellite. The UT estimates a respective timing delay and frequency shift of the downlink data transmissions based on the tracked frame timing and frequency of the downlink data transmissions. The UT receives satellite ephemeris data broadcast by the satellite. The UT synchronizes uplink data transmissions to the satellite based on the estimated timing delay and frequency shift of the downlink data transmissions, the received satellite ephemeris data, and knowledge of a UT position and velocity vectors associated with any movement of the UT.

Abstract: An approach is provided for reliable provision of targeted, status-based messaging to a client terminal in a computer network, such as a wide area resource-based network. A terminal node receives a message originating from a client terminal, wherein the terminal node serves as an entry point to, and services communications connections over, a wide area network for the client terminal. The terminal node determines that the message comprises an initiation request for establishing a communications connection over the wide area network between the client terminal and a remote server, and that an intercept state is in effect. The terminal node establishes the communications connection as a local connection between the client terminal and the terminal node, and services the communications connection via a local server function, wherein the servicing of the communications connection via the local server function comprises a provision of status-based messaging to the client terminal.
