Abstract: A compact, highly flexible and efficient, multi- positionable, multi-dimensional and multi-stage gas-fired heat exchanger system as described. The system is connectable in a forced air duct regardless of the angular position and size of the duct. The heat exchanger comprises one or more heat transfer tubes which are shaped and dimensioned as dictated by the customized use of the heat exchanger. The tubes are secured to a support panel as well as the gas burner associated with each of the inlet openings of the tubes. A position orientable gas valve is secured to a gas distribution manifold. A turbulator may be associated with at least some of the tubes to cause turbulence in the hot combustion flow in each of the tubes to modify the efficiency in heat transfer along one or more sections of the tubes by directing hot combustion gas along an inner circumferential wall of the tubes. The outlet of the tubes connect to a collector which has an exhaust fan which is position orientable to suit the installation of the heat exchanger in the duct.

Granted: 2005-08-16
Abstract: A wet friction plate of a hydraulic clutch or hydraulic brake for an automatic transmission having a reduced friction resistance in a non-engaged state. A  plurality of friction materials disposed in an annular shape with a plurality of radial oil passages each provided between the adjacent friction materials are mounted at two radially inner and outer stages on a surface of a friction plate of a wet hydraulic clutch of an automatic transmission. The friction materials are brought into contact with an annular separator plate to transmit a torque. Inner peripheral edges of each of the friction materials are formed into a V-shape toward a radially outer side. Thus, when the friction plate and the separator plate are in non-engaged states, a lubricating oil remaining between both the plates can be guided effectively to the radial oil passages by a centrifugal force and discharged to the outside, and a friction resistance due to the dragging of the lubricating oil can be reduced to avoid the generation of an energy loss.

Granted: 2005-11-29
Abstract: A method of robotic assembly, for manufacturing plastic components from parts mounted upon a plastic shell, using an integrated system of material handling and robots following a programmed series of operations. The robot cells carry out the following steps: (a) scanning the pallet and identifying that the pallet is locked in the docked position of the cell; (b) scanning an assembly area of the shell and communicating location and planarity data to the robot of the cell; (c) selecting a plastic part from a part supply device with the robot; (d) welding the part to the assembly surface of the plastic shell using the robot to perform a spin or fusion welding process. The spin welding process includes: engaging a mounting surface of the part with the assembly surface of the shell; rotating the part until the mounting and assembly surfaces are heated; and applying pressure to the part sufficient to fuse the mounting and assembly surfaces together. The fusion welding includes: simultaneously heating the mounting and assembly surfaces with heaters; and applying pressure to the part sufficient to fuse the mounting and assembly surfaces together; (e) determining the performance status of the foregoing cell steps and identifying the status as: good; scrap or rework. Good status results in conveyance of the loaded pallet for processing at any succeeding cell, but rework and scrap status result in conveyance of the loaded pallet to the unload station without processing at any succeeding cell.

Title: Protection system and method for resilient packet ring (rpr) interconnection
Inventor: LEE BYOUNG-JOON
IPC: H04L12/56
Filed: 2002-07-10
Granted: 2010-03-16
Abstract: A failure protection between interconnected adjacent Resilient Packet Rings (RPRs) in a multiple RPR network is provided. Two paths, a regular message path and a protection path, are provided between two adjacent RPRs. The regular path is used for routing inter- ring messages when no failure has occurred on the path. Messages are rerouted through the protection path when a failure occurs on the regular path. Each of these paths has two RPR interface nodes (one for each RPR) that are connected to an interconnection device (a layer 2 bridge or a layer-3 router) through interconnection links. Procedures for detecting failures and generating notifications for message rerouting and fault reports are executed at the interconnection devices. The procedures use periodic keep alive messages for diagnosing network segment and interconnection device failures. The fault detection and message rerouting are accomplished in less than 50 ms.
