| 20090287391 | Engine Fuel Control System - A fuel control system is provided. The fuel control system includes an electronic control system coupled to a pair of control valves for blending pipeline fuel with waste fuel at a blend ratio for controlling fuel flow to an internal combustion engine. The fuel control system can estimate energy content of the fuel mixture to compensate the blend ratio. The fuel control system can use engine operational parameters to compensate the blend ratio. Typically, the system will use the operational parameter of output power or exhaust emissions to compensate the blend ratio. Further, the fuel control system can prioritize variation from the blend ratio or variation from a desired power output when the blend ratio cannot generate the desired power output. The fuel control system can also be equipped with engine speed/load controls, misfire, ignition timing and knock detection capabilities. | 11-19-2009 |
| 20100000204 | Passive Secondary Air Delivery System for Two Bed Catalyst System - A passive secondary air delivery system for a two bed catalyst is provided. The system delivers passive secondary air to the second catalyst bed to facilitate oxidation of CO and remaining unburned HC. In a turbocharged engine, the secondary air may be provided from the compressor side of the turbocharger. Control of the amount of air bled from the turbocharger is provided by an orifice in the pipe connecting the turbocharger to the catalyst bed. No active controls are required. In non-turbocharged engines, passive secondary air may be provided by a venturi mixer ported to ambient positioned between the two catalyst beds. In either embodiment, no moving parts or active controls are required. | 01-07-2010 |

| 20090191053 | Diaphragm and blades for turbomachinery - A diaphragm for an axial flow turbomachine, in which outer shrouds of adjacent fixed blades in a row of blades contact each other circumferentially to form a circumferentially continuous load path. Inner shrouds of the blades only contact each other on contact faces oriented to transmit loads in the radial and/or axial directions of the turbomachine. | 07-30-2009 |

| 20090175722 | STEAM TURBINES - A steam turbine is provided that is configured for post-modification for operation in a carbon capture mode. The turbine includes a turbine rotor, a turbine casing and a plurality of turbine stages. In an initial configuration of the turbine, the turbine rotor and turbine casing are each longer, by respective lengths, than is necessary to accommodate the plurality of turbine stages. The lengths are sufficient to accommodate at least one further turbine stage at an exit of the turbine during the post-modification, such that after modification, the turbine operates with an increased expansion ratio and an increased volumetric flow rate at the exit. | 07-09-2009 |

| 20110155152 | Tobacco Treatment - This invention provides a method for removing undesirable constituents from tobacco which includes extracting tobacco material in an aqueous or organic solvent and filtering the product of the extraction using a horizontal belt filter. The extract and insoluble tobacco residue may be further treated enzymically, chemically or otherwise to remove a complement of undesirable constituents. The extract and insoluble tobacco residue are recombined to form a regenerated tobacco material that is less harmful when combusted than the original material. | 06-30-2011 |
