| 20110081242 | ENHANCED AXIAL AIR MOVER SYSTEM WITH ENCLOSURE PROFILE - 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. | 04-07-2011 |
| 20140010644 | COMBUSTOR TRANSITION DUCT ASSEMBLY WITH INNER LINER - A transition duct assembly for a turbine engine includes a transition duct with an inner liner removably received therein. The duct is hollow with an inner peripheral surface and an outer peripheral surface. The duct can have an inlet end and an outlet end. The inner peripheral surface of the duct can be convergent along a majority of the length of the duct when moving from the inlet end to the outlet end thereof. The liner is hollow body with an inner peripheral surface and an outer peripheral surface. The outer peripheral surface of the liner can be correspondingly convergent to the inner peripheral surface of the duct. The inner peripheral surface of the liner can define an internal flow passage through the assembly. Such a construction permits the use of different materials for the liner and the duct and can allow the liner to be readily removed and replaced. | 01-09-2014 |
| 20140064959 | AXIAL FLOW FAN - A leading edge of a rotating blade of an impeller is formed in an arc recessed in a direction opposite to a rotating direction of the impeller. An angle where an extended line of the recessed arc of the leading edge meets another extended line of a curve of a side edge is set in an acute angle of 30 to 37 degrees in a front view so that a leading tip of the rotating blade may be projected in the rotating direction. An opening angle of a suction-side slant portion of a venturi casing is set in the range of 12 to 17 degrees and an opening angle of a discharge-side slant portion is set in the range of 30 to 35 degrees. | 03-06-2014 |
| 20140314562 | FAN SYSTEMS - A fan system may generate an air flow during use. In various implementations, a fan system may include a fan and an orifice. The orifice may include a converging section, a diverging section, and a minimum radius section disposed between the converging section and the diverging section. | 10-23-2014 |
| 20150010398 | TURBOCOMPRESSOR - A turbocompressor that is suitable for conveying a multi-phase mixture, comprising a housing having a guiding device and comprising a shaft having at least one impeller, wherein the turbocompressor has an expansion chamber through which the multi-phase mixture can flow on the suction side and a contraction chamber arranged downstream is provided. | 01-08-2015 |
| 20150050140 | INTAKE ARRANGEMENT IN GAS TURBINE POWER PLANT - An improved intake arrangement, for a compressor having a compressor blading, includes a manifold divided by a barrier into two sections, to convey, from one section, a flue gas stream, and, from other section, an air stream. Further, the intake arrangement includes a converging section configured to the manifold and extends convergingly to the compressor defining an inlet to the compressor blading. The converging section includes inner and outer ring members disposed coaxially to each other, between which there extends, coaxially and convergingly, the barrier to at least up to a certain distance within the converging section, defining a converging nozzle therebetween. The converging nozzle includes a mixing feature adapted to enhance mixing of the flue gas and air streams. | 02-19-2015 |

| 20160146026 | TRANSITION DUCT ARRANGEMENT IN A GAS TURBINE ENGINE - An arrangement for a gas turbine engine includes a combustor for producing a working medium by combustion of a mixture of fuel and an oxidant, a turbine section comprising a stationary vane carrier on which a first row of stationary vanes is arranged, and a transition duct for leading the working medium from the combustor to the turbine section. The transition duct has a forward end that adjoins the combustor and an aft end that adjoins the stationary vane carrier. The transition duct has a transition duct axis extending from the forward end to the aft end along a straight line. The transition duct axis is normal to a vane axis of a stationary vane in the first row of stationary vanes. | 05-26-2016 |
