Patent CA-2129064-A1 (CA)
Inventor: CRAWMER DARYL E
IPC: B05B7/22
Filed: 1994-07-28
Abstract: An improved plasma arc spray gun performs with higher deposition efficiency and longer lasting anodes and cathodes than prior spray guns. The spray gun of the invention includes a housing made of a glass fiber reinforced TORLON material that remains dimensionally stable under all operating conditions. The anode of a relatively low velocity subsonic spray gun has an interior with five sections, two of which have cylindrical inner surfaces and three of which have frusto-conical surfaces. The cathode tip is carefully located within the anode interior such that the electrical arc between the anode and cathode attaches to the anode at a circular line at a junction of a cylindrical surface and a frusto-conical surface. Relatively high velocity subsonic versions of the plasma arc spray gun utilize anodes with three interior sections and streamlined passages for vortex stabilized flow of the primary gas. The primary gas flows in a vortex such that the point of attachment of the arc to the anode travels continuously along the circular line to reduce anode wear. The improved gas dynamics cools the cathode tip and thereby increases its service life.

Title: Frame relay protocol-based multiple switching scheme for satellite mesh network
Inventor: FIELDING DENNIS E
IPC: H04J3/26
Filed: 1994-06-16
Abstract: A frame relay protocol-ba ed earth station interface architecture provides full mesh connectivity for a relatively small number of network stations. The fundamental component of the architecture is a frame relay proctocol-based switch (110), which employs a network interface "frame realy" standard to define the multiplexing of multiple virtual ports across single physical communications port. Through address and control fields of its connectivity control software, the frame relay protocol-based switch (110) can be dynamically configured to provide multilayer addressing and device selectivity, thereby enabling point-to-point connectivity of multiple terminal devices, such as a plurality of audio circuits (170-1...170-N), to be effected via a single port. Dial codes on the station side of an audio signal multiplexer link (135) are translated into frame relay addresses (data link connection identifiers) that are added to each frame of data for routing through the network.
