Patent CA-2538334-A1 (CA)
Inventor: VATSYA S RAJ
IPC: G02B6/122
Filed: 2006-02-28
Abstract: A computer-based design methodology for photonic bandgap devices that permits determination of both the upper and lower bandgap edges in either a one-dimensional or two-dimensional photonic crystal. Using this methodology, a one-dimensional crystal may be created for use in a waveguide-fed microwave oven as a radiation reflector-suppressor, particularly for undesirable higher harmonic frequencies of about 12 GHz. By conceptually arranging multiple reflectors in a desired geometry, a two--dimensional crystal may be created that is particularly useful as a waveguide or splitter. The waveguide or splitter thus created has especially high efficiency for microwave wavelength ranges of about 9 GHz as compared with the prior art and is particularly useful in communications applications.

Patent CA-2555652-A1 (CA)
Title: A rotary motor and a method for its manufacture
Inventor: FRIEDRICH THOMAS
IPC: B23F17/00
Filed: 2006-08-08
Abstract: The present invention relates to a rotary motor, preferably a pivot drive for construction machinery, trucks and the like comprising an elongate housing, preferably an approximately tubular housing, a piston displaceably received in the housing, which is axially displaceable by charging with a pressure medium in a pressure chamber, and a shaft received axially fixedly, but rotatably in the housing, with the piston being in screw engagement with the shaft and/or the housing.  The invention furthermore relates to a method for the manufacture of such a rotary motor. The present invention departs from the previous approach of separating the sealing of the piston at the shaft and at the housing from the section effecting the rotary guide or the screw engagement. In accordance with the invention, a surface pair of piston and shaft and/or of piston and housing effecting the screw engagement can simultaneously form a sealing surface pair for the sealing of the pressure chamber for the charging of the piston with pressure. The same piston section simultaneously serves the transfer of torque and sealing. A  considerably reduced construction length can hereby be achieved since the axial spacing between the sealing section and the rotary guide section or the screw engagement section of the piston is omitted. In addition, the respective components, in particular the housing and the shaft, can be manufactured in an endless manner and be produced as needed and in the required length.

Title: Fumigation system for a diesel engine
Inventor: JONES TERRY A
IPC: F02D41/14
Filed: 2005-03-10
Abstract: A system and method is provided to reduce particulate and NOx emissions from diesel engines through the use of a duel-fuel fumigation system. The system injects a gaseous-fuel flow into the air intake stream of a diesel engine.  This results in more complete combustion within the engine as well as reduced diesel fuel usage, which each work to reduce emission outputs of the engine.  As presented, the system is operative to meter the gaseous-fuel flow into the diesel engine based on one or more engine parameters such as, for example, exhaust gas temperature, exhaust oxygen levels, engine speed and/or engine load. Monitoring one or more engine parameters allows fine-tuning the flow of gaseous fuel into the engine and thereby prevents loss of engine power at high-end loads while maintaining favorable emission outputs over substantially the entire operating range of the engine.
