Patent CA-2286704-A1 (CA)
Title: Fuel injector and method using two, two-way valve control valves
Inventor: STURMAN ODED E
IPC: F01L9/10
Filed: 1998-04-09
Abstract: A fuel injector (18) that contains no springs and is controlled by a valve assembly that has more than two modes of operation. The fuel injector includes a housing which has a supply port (36), a drain port (44) and a cylinder passage (38) that is in fluid communication with an intensifier (80). The intensifier moves between a first position and a second position within a fuel chamber (36). The fuel chamber is coupled to a fuel port. Movement of the intensifier into the second position pressurizes the furl within a fuel chamber (36). The pressurized fuel opens a needle valve (110) so that fuel is ejected through an aperture (76) of the housing. The cylinder passage is coupled to a first fluid control valve (32) and a second fluid control valve (34). Each control valve can be actuated between a closed position and an open position. When the first control valve is moved to the open position, the supply port is in fluid communication with the cylinder passage so that a fluid flows through the passage to push the intensifier (80) to the second position and eject fuel from the ejector. When the second control valve (34) is actuated to the open position the cylinder passage is coupled to the drain port (44). The intensifier is coupled to a supply line that provides fluid to move the intensifier back to the first position; the needle is also coupled to the return line (114) to move the needle back to a closed position.

Each sensor is constructed such that a reference element, such as a rigid element, isolates a reference location in the optical fiber from mechanically induced strain. A Bragg grating sensing element is positioned with respect to the reference element, and responsive to an optical signal and to a strain associated with a respective measurand field for providing an optical sensing signal related to a magnitude of the respective measurand field.

Title: Method of removing hot corrosion products from a diffusion aluminide coating
Inventor: ROSENZWEIG MARK ALAN
IPC: F01D25/00
Filed: 1999-12-16
Abstract: A method of removing hot corrosion products from the surface of a component exposed to corrosive conditions at elevated temperatures, as is the case with turbine, combustor or augmentor components of gas turbine engines. The method is particularly suited for the removal of hot corrosion products from components protected with a diffusion aluminide coating, either as an environmental coating or as a bond coat for a thermal barrier coating (TBC). The processing steps of the method include immersing the component in a heated liquid solution containing acetic acid, and then agitating the surfaces of the component while the component remains immersed in the solution. In this manner, hot corrosion products on the surfaces of the component are removed without damaging or removing the diffusion aluminide coating. As a result, regions of the component from which the hot corrosion products were removed can then be repaired by a suitable aluminizing process.

Filed: 2000-03-01
Abstract: A programmable optical demultiplexer (or switch) employing index-modulated electro-optical (or thermo-optical) polymeric grating-coupler array in conjunction with substrate guided wave is proposed. These modulated grating-couplers are produced by a modulating signal (voltage) applied to electrodes with grating patterns. Different electro-optic grating-couplers in the grating-coupler array have different coupling wavelengths so that each of them can couple a selected wavelength out from the substrate guided waves. This architecture can be used as a programmable demultiplexer to implement reconfigurable wavelength-division-multiplexed (WDM) optical systems.
