Patent CA-2254885-A1 (CA)
Title: Turbomachine rotor cooling
Inventor: HULTGREN KENT G
IPC: F02C7/18
Filed: 1997-03-19
Abstract: A gas turbine rotor has an essentially closed loop cooling air scheme in which cooling air drawn from the compressor discharge air that is supplied to the combustion chamber is further compressed, cooled, and then directed to the aft end of the turbine rotor. Downstream seal rings attached to the downstream face of each rotor disc direct the cooling air over the downstream disc face, thereby cooling it, and then to cooling air passages formed in the rotating blades. Upstream seal rings attached to the upstream face of each disc direct the heated cooling air away from the blade root while keeping the disc thermally isolated from the heated cooling air. From each upstream seal ring, the heated cooling air Nows through passages in the upstream discs and is then combined and returned to the combustion chamber from which it was drawn.

Title: An improved method for network address translation
Inventor: ARAVAMUDAN MURALI
IPC: H04L29/12
Filed: 1999-01-26
Abstract: A method for translating non Internet unique addresses of a home network device to an Internet unique address for internet communication through a router. Every device within a given home network is assigned three addresses:(i) a configured address identical to the network address of the router enabling access to an Internet; (ii) a logical address visible only to the other devices in the same home network; and (iii) a medium access control ("MAC") address. Every packet originating from a home network source device includes its MAC address, the router MAC address, its configured address and the network destination address, and is forwarded to its destination through the router. The router examines the network destination address to determine whether the communication is intranet or internet. For intranet communications the router replaces the configured address of the home network source device with the logical address of the home network source device, the logical address of the home network destination device with the configured address, its MAC  address with the MAC address of the home network destination device, and forwards the packet to the home network destination device. For Internet communications the router forwards the packet along the Internet without replacing any of the source or destination information in the headers of the packet. Based on the source MAC address, however, the router records the logical address of the home network source device as well as the DA, SP, DP and PT in order to identify a response to the packet from the Internet destination device.

Title: Refrigerator door corner construction
Inventor: ESTRAVILLO ARNOLD
IPC: F25D23/02
Filed: 1999-05-27
Abstract: The present invention relates to a door for a refrigerator appliance having reinforcing corner brackets that structurally complete the corners of the door. The corner brackets are located at the door corners of the vertical and horizontal side walls of the outer door skin. The brackets structurally replace and reinforce the horizontal side wall immediately adjacent the vertical side wall with a thicker, stronger material, such as, for example, metal or steel, so that loading normally transferred to the outer door skin through the horizontal side wall at this corner location is instead transferred directly to the brackets mounted in the door. The horizontal side wall at the corner adjacent the vertical side wall has a cut-out or an open section. The brackets each have an opening positioned at the cut-out section. The opening is adapted to receive a hinge pin or closure cap. The door has an elongate supporting strut in the form of a hollow cylindrical tube engaging the brackets to reinforce the corners.      The strut extends adjacent the one vertical side wall for supporting the corner brackets within the door to reinforce the door. Reinforcement brackets and tubes are located on each side of the door.
