Title: Abrasive fluid jet system
Inventor: GADD MICHAEL WILLIAM
IPC: B24C1/04
Filed: 2002-04-22
Granted: 2010-07-13
Abstract: The invention provides an abrasive jet system having a high-pressure fluid supply (10) means supplying fluid to a vessel (11) which includes a layer of abrasive slurry and a top layer that contains substantially of fluid over the layer of abrasive slurry. The system also includes a first conduit (14) which leads from the fluid supply means to the top layer of fluid in the vessel and as high-pressure fluid is fed into the vessel, causes displacement of abrasive slurry from a discharge conduit (16). The system further includes a second conduit (21) which connects at different points to the first conduit and the discharge conduit, and including a fluid valve (13) between the operative connection to the first conduit and the discharge conduit, that controls the fluid flow within the second conduit. The fluid valve is closed once the system is pressurised to displace abrasive slurry through the discharge conduit (16) and is opened upon de-pressurization of the system to allow fluid flow from the first conduit (14) to the second conduit and to stop discharge of the abrasive slurry.

Title: Transmission system for efficient transmission of protocol data
Inventor: ICHINO KIYOHISA
IPC: H04L1/00
Filed: 2003-12-19
Granted: 2008-04-08
Abstract: A transmission system is disclosed that has small circuit scale and small memory capacity, and moreover, in which higher-layer protocol data are transmitted with little transmission delay. A sending device converts the higher-layer protocol data to continuously valid blocks of a fixed length for frames on the transmission path. The sending device next matches a sending rate to a transmission rate of a transmission path by inserting idle blocks between valid blocks and then transmits. Relay devices receive the valid blocks and idle blocks from the sending device, and discard the idle blocks to extract the valid blocks. The relay devices further match a sending rate to a transmission rate of a transmission path on a transmission side by inserting idle blocks between the valid blocks and transmitting the blocks to a prescribed transfer destination. A receiving device receives the blocks and idle blocks from a final-stage relay device and then discards the idle blocks to extract only the valid blocks. The receiving device finally reconstructs the higher--layer protocol data from the valid blocks.

Title: Method of adhesive bonding by induction heating
Inventor: RIESS EDWARD A
IPC: H05B6/02
Filed: 2000-11-02
Granted: 2007-07-10
Abstract: An apparatus and system for using magnetic fields to heat magnetically susceptible materials within and/or adjacent to adhesives, resins, or composites so as to reversibly or irreversibly bond, bind, or fasten opaque or non-opaque solid materials to one another. The system makes use of the effect that alternating magnetic fields induce eddy currents and generate heat within susceptors, and the effect that alternating magnetic fields additionally induce magnetic hysteresis that occurs in magnetic materials and thereby generate heat. An induction heating tool is used to emit the magnetic field at its work coil, and an electronic controller measures the energy being used by a power converter that generates the alternating current driving the work coil which creates the magnetic field. The distance between the susceptor and work coil is repeatedly analyzed based upon the power converter's input energy, and the work coil is driven at a repeatedly corrected power level during the heating cycle. Once a sufficient accumulated energy has been delivered to the susceptor, the magnetic field is turned off automatically by the tool, thus preventing overheating of the susceptor.
