Title: Multi-hop packet radio networks
Inventor: LARSEN MARK SIEVERT
IPC: H04L12/56
Filed: 1995-12-19
Abstract: An adaptative communication system utilizes opportunistic peak-mode transmissions to transmit data between originating and destination stations, via one or more intermediate stations. Each station monitors the activity of other stations in the network, storing connectivity information for use in subsequent transmissions. Each station also sends out probe signals from time to time, to establish which other stations are in range. Messages are then sent across the network from station to station, with confirmation data being transmitted back to the originating station, until the destination station is reached. Old messages, which would otherwise clog the network, are timed out and deleted. A communication network and transceiver apparatus for use in the network are also disclosed.

Abstract: A method and apparatus for performing CORBA transactions utilizing workstation computers involves a client computer, and one or more server computers implementing CORBA's OTS. The client computers creates a new transaction and requests that an object be invoked. The client provides a combination Coordinator/Recovery Coordinator object to the server computer. The server computer creates its own Coordinator/Resource/Recovery Coordinator object to handle the transaction. Within the object invocation, a resource is created and registered with the client's Coordinator object. The method returns and replies to the client, providing the server's Coordinator object. The Coordinator object is thus implicitly registered with the client computer. If this transaction involves invocation on other objects, the client will provide the first server's Coordinator object rather than its own to the subsequent servers.

Filed: 1996-11-01
Abstract: A froth crowder device (10) is disclosed for incorporation into a froth flotation cell (12) to improve the froth removal dynamics of the flotation cell. The froth crowder device (10) is positioned within a froth flotation cell (12) above and below the overflow launder, and provides a sloped surface to direct froth toward the overflow launder (28) in an expedited manner. Experimental data confirms that use of a froth crowder device (10) as disclosed expedites movement of the froth toward the launder (28) for more efficient operation, permits operating the rotor (46) of the flotation cell (12) at reduced speeds without compromising the efficiency of operation, and reduces the amount of air necessary to produce a froth in the cell. Experimental data also confirms that little or no surface eddies are observed in froth flotation cells (12) in which a crowder device (10) as disclosed is used. By comparison, flotation cells without use of a crowder device experience increased occurrences of surface eddies which traps the froth within the tank and extends froth residency time to the ultimate detriment of separation efficiency.
