Abstract: A gas turbine vane (17) having an inner shroud (26) that is cooled by a portion of the cooling air directed to a cavity (45) between two adjacent rows of discs (55, 56). A portion of the cooling air in the cavity flows through impingement plates (83, 84) and impinges on the inner (98) surface of the inner shroud (26). Another portion of the cooling air flows through a passage (88) in the leading edge (42) of the inner shroud that has a pin fin (89) array for enhanced cooling. The impingement plates form chambers that collect both the impingement air and the pin fin passage air and direct it through holes (92) in the trailing edge (43) of the inner shroud for cooling of the trailing edge. Longitudinal passages (93, 94) along the side of the inner shroud direct the cooling air from the pin fin passage to the trailing edge (43).

Granted: 2009-08-11
Abstract: The present invention provides a modified microorganism which produces an RTX  toxin, wherein said RTX toxin is partially or fully inactivated. In a further embodiment of the present invention, there is provided a modified microorganism wherein an RTX toxin gene including an RTX structural gene and/or a post-translational activator of the organism is partially or fully inactivated. The present applicants have found that a precursor of an RTX toxin has reduced toxic activity.  Surprisingly, the RTX toxin precursor is capable of inducing an immune response in an animal that offers cross protection against heterologous challenge with a microorganism which produces the RTX toxin. A microorganism which naturally produces an RTX toxin may be engineered to produce an inactive RTX toxin precursor by eliminating the post-translational activator of the precursor product.  Accordingly, in a preferred embodiment the microorganism is unable to produce a post-translational activator of the RTX toxin precursor or produces an inactivated post-translational activator of the RTX  toxin precursor. The post-translational activator may be a product of an RTX C  gene. In a further aspect the present invention provides a recombinant plasmid vector for expression of heterologous proteins in Actinobacillus or related organisms. In a preferred embodiment the recombinant plasmid vector is derived from a naturally occurring plasmid in Actinobacillus pleuropneumoniae. The recombinant plasmid may include a DNA sequence which encodes an RTX toxin precursor. The recombinant plasmid may include an RTX A gene. Alternatively, the recombinant plasmid may include an RTX C gene or a fragment thereof.

Title: Air and fuel system for carburetor and fuel injection systems
Inventor: COX CARL C
IPC: F02M25/10
Filed: 1998-06-22
Granted: 2004-05-25
Abstract: An air and fuel system for carburetor and fuel injection engines that regulates the temperature of air and fuel that is mixed in the carburetor or fuel injector prior to introduction to the cylinders of the engine. A heater and associated filter located at the air intake side of the carburetor are activated by circulating heated fluid (coolant) contained within the engine cooling system. The coolant passes through the heater in an isolated chamber or conductor and the fuel line passes inside the coolant line within the heater surroundings so that air and fuel can be temperature regulated. Valves in the fuel line allow for proper mixture of air and fuel. A filter is sized to fit inside or outside the heater, and the heater and filter are encompassed by a cover to hold the components together.      Oxygen is introduced to the system to reduce air pollution and oxygen and fuel vapors combine to create a high explosive fuel that burns efficiently and thereby reduces air pollution.
Patent CA-2241660-C (CA)
Inventor: CARROLL JOHN B
IPC: B60T15/02
Filed: 1998-06-26
Granted: 2002-02-19
Abstract: The invention provides an electrically activated valve assembly for control of a fluid. It has a diaphragm with a control chamber on one side and a flow barrier on the second side. Portions of a first flow passage and a second flow passage are on the second side of the diaphragm, with the flow barrier between them. When the control chamber has a relatively high pressure, the diaphragm is pressed against the flow barrier, isolating the first flow passage from the second flow passage. When the control chamber has a relatively low pressure, the diaphragm moves away from the flow barrier, so flow may occur between the first flow passage and the second flow passage. The position of the diaphragm is determined by pressure in the control chamber so the pressure in the control chamber controls the fluid flow connection between the first flow passage and the second flow passage. The valve also has an electrically activated valve responsive to an electrical signal to control pressure in a flow passageway to the control chamber so that when the electrically activated valve is energized, the control pressure is changed, so the electrically activated valve controls the fluid flow connection between the first flow passage and the second flow passage.
