20100150713 | Rotating-Plate Radial Turbine in Gas-Turbine-Cycle Configurations - A novel power-producing concept is disclosed, employing a rotating-plate radial gas turbine in various gas-turbine cycle configurations. The “rotating-plate radial gas turbine” is a rotating barrel with robust rectangular plates fitted into the turbine rotor, performing the function and the role of turbine blades, contained within a motionless rigid horizontal cylinder (casing). Combustion can take place in the spaces confined between adjacent rotating plates and the static cylinder, thus enabling a practical achievement of the Atkinson cycle (constant-volume heat addition) with improved cycle thermal efficiency. Alternatively, two or more compressor stages can be combined to feed a single rotating-plate radial gas turbine in cascades, thus gradually increasing pressure of working gas within a volume bordered by adjacent un-cooled rotating plates of the radial gas turbine and the casing. Alternatively, a single compressor may be combined with one or more stages of an axial turbine for cascade feeding of a single rotating-plate radial gas turbine. This “isochoric stuffing” effect enables achievement of significantly and even drastically improved gas-turbine-cycle thermal efficiencies. Cycle heat addition may be either isobaric or isochoric in either an open-cycle or a closed-cycle configuration. Using a sufficiently efficient radial gas turbine, it is theoretically possible to obtain 100% cycle thermal efficiency in a simple radial-gas-turbine configuration with appropriately chosen compressor-stages compression pressure ratios. | 06-17-2010 |

20150147171 | ENHANCED AXIAL AIR MOVER SYSTEM WITH ALIGNMENT - Implementations of an enhanced axial air mover system address various issues such as drying performance, transportability, storage, use, and assembly. Some implementations include ergonomic positioning of a carrying handle relative to positioning of a fan-assembly to make the system easier to carry. Enclosures with variable diameter profiles increase air flow performance. A floor edge allows for flush positioning of the air mover's outlet to improve flow of air. Various supports and engagement members allow for horizontal and/or vertical engagement of a plurality of the air movers for storage or increased air moving capacity for a given application. An alignment guide assists with positioning of the air mover with respect to a room wall to enhance air flow within the room. A cord retaining system provides an enhanced approach for securing the air mover's electrical cord. Grill guards have slotted ends to assist with assembly of the air mover. | 05-28-2015 |
