Abstract: A gearbox support apparatus includes: a gearbox carrier having a central axis, the carrier configured to mount one or more rotating gears therein, the carrier including spaced-apart forward and aft walls, and a flexible center plate structure disposed between the forward and aft walls, an annular support ring disposed axially adjacent to the carrier; and a plurality of axially-extending torque fingers interconnecting the mounting ring and the center plate structure.

Abstract: A dry cleaning machine includes a tub for holding articles to be cleaned. A door is rotatably coupled to the dry cleaning machine. The door is movable from a closed position wherein access to the tub is substantially sealed, to an open position providing access to the tub. An outlet tube is coupled in flow communication to the tub. A filter assembly is positioned between the tub and the outlet tube filtering dry cleaning fluid channeled towards the outlet tube.

Abstract: Method and apparatus for recovering and purifying a solvent used in an article cleaning appliance are provided. The method allows passing solvent-based cleaning fluid from a wash basket through a coarse filter configured to remove relatively large particulates from the cleaning fluid. The method further allows passing cleaning fluid from the coarse filter through a particulate filter configured to remove relatively fine particulates from the cleaning fluid. An aqueous phase that may be present in the cleaning fluid is separated by decanting and coalescing through a separator/filter assembly. The cleaning fluid may then be passed through a regeneration cartridge for removing any water that may remain in the cleaning fluid, and for adsorbing organic contaminants that may be present in the cleaning fluid. Recovered solvent may be stored in a tank for subsequent use in a cleaning process performed by the appliance.

Abstract: An apparatus and method for controlling air temperature in an appliance. The apparatus includes an air cooling unit disposed in an airflow path and an air heating unit disposed in the airflow path and fluidically coupled to the air cooling unit by a refrigerant. The apparatus also includes a de-heater fluidically coupled to the air cooling unit and the air heating unit by the refrigerant to controllably dissipate heat from the refrigerant.

Abstract: The present invention provides methods and compositions for cleaning using dual phase wash solutions. The dual phase wash solutions comprise emulsions of polar and non-polar solvents with emulsifiers, surfactants and detergents. The methods of the present invention comprise the steps of charging an article to a washing machine comprising a washing drum, exposing the article in the wash drum to a wash solution comprising 0.125 to 20 percent water; a detergent comprising an ionic surfactant, a non-ionic surfactant and an emulsifier; and decamethylcyclopentasiloxane, agitating the article and wash solution in the washing drum, draining the wash solution from the drum, optionally, adding a rinse solution comprising substantially the same components as the wash solution; agitating the article in the rinse solution; and separating the rinse solution from the article by allowing the rinse solution to drain out of the drum and spinning the drum to drive off residual rinse solution through centrifugal force.

Abstract: An imaging tube assembly (11) for a computed tomography (CT) system (10) includes an insert (60) that has a vacuum chamber (72). An anode (58) resides within the vacuum chamber (72) and rotates on a shaft (66) via one or more bearing (70). In one embodiment, a seal (52) resides between the insert (60) and the shaft (66). The seal (52) prevents the passage of a gas (80) into the vacuum chamber (72). In another embodiment, a pressure transition chamber (104) is coupled to an insert (60?) and a shaft (66?). The pressure transition chamber (104) has an associated middle fluid pressure that is between an internal fluid pressure of the vacuum chamber (104) and an external fluid pressure of said insert (60?).

Abstract: An apparatus for active vibration is provided for control of resonance vibrations in a computed tomography (CT) system. The apparatus comprises a sensor coupled to a support frame of the CT system for detecting resonance vibrations and and convert the vibration signal to a corresponding electrical signal. The apparatus further comprises a control device coupled to the sensor for implementing a control algorithm to process the electrical signal to generate a corresponding control signal, which is used for counteracting the resonance vibrations in the support frame.

Abstract: A dry cleaning device includes a cleaning enclosure suitable for receiving clothing articles and a cleaning fluid, typically a solvent based cleaning fluid, and circuitry coupled to the dry cleaning device for sensing at least one operational parameter of the dry cleaning device and for calculating a retained cleaning fluid content in the articles disposed within the cleaning enclosure based on the at least one operational parameter. Alternatively, the circuitry may calculate the amount of cleaning fluid returned to the system during the cleaning process.

Abstract: The present technique provides systems and methods for integrally washing and drying laundry articles in a home application. Certain embodiments provide a home laundry machine having a drying mechanism pneumatically coupled to a laundry enclosure via an air inlet and an air outlet. The drying mechanism comprises a heating device disposed upstream of the air inlet and a cooling device disposed downstream of the air outlet.
