Abstract: The present disclosure provides a radiator assembly that includes a stationary assembly that includes a fan assembly coupled to a fan frame assembly, a rotating assembly that includes a radiator frame assembly and a support frame assembly coupled to the radiator frame assembly, and an actuation assembly coupled to the rotating assembly. The rotating assembly may be rotatably coupled to the stationary assembly and configured to rotate relative to the stationary assembly in a first direction and a second direction opposite the first direction. The actuation assembly may be configured to enable and limit rotation of the rotating assembly relative to the stationary assembly in the first direction and the second direction.

Abstract: The present disclosure relates generally to semiconductor structures, and more particularly to asymmetric field effect transistors (FET) on fully depleted silicon on insulator (FDSOI) semiconductor devices for high frequency and high voltage applications and their method of manufacture. The semiconductor device of the present disclosure includes a semiconductor-on-insulator (SOI) layer disposed above a substrate, the SOI layer having a source region, a channel region, a drift region and a drain region, where the drift region adjoins the drain region and the channel region, a gate structure disposed on the channel region, a multilayer drain spacer disposed on a drain-facing sidewall of the gate structure and covering the drift region, and a source spacer disposed on a source-facing sidewall of the gate structure, where the source and drain spacers are asymmetric with each other.

Abstract: A flexible cleaning device with a handle having a first end and a second end, a malleable head at the first end of the handle, a cover selectively covering at least a portion of the malleable head, and a grip at the second end of the handle. A fluid reservoir may be supported on the handle or the malleable head, and a fluid deposition system provided and adapted to selectively deposit fluid from the reservoir onto a surface to be cleaned. The malleable head may be attached to a rigid structure at the second end of the handle, and have a non-absorbent flexible structure adapted to conform to grout lines in a typical tiled floor surface. An air inlet may be attached to the device, and an air passage provided and adapted to connect the air inlet to a suction source.

Abstract: A fiber-optic connector having a transparent connector housing, having a fiber receptacle hole for receiving a fiber-optic cable end which has an insulating sheath and an optical waveguide, the connector housing having an opening which extends transversely with respect to the fiber receptacle hole and is connected thereto, the connector including a fiber holding clip that can be introduced through the opening in order to retain the fiber-optic cable end, that is positioned against a stop, the fiber holding clip being pretensioned in such a way that the fiber-optic cable end is guided in follow-up fashion against the stop in the event of length variations.

Abstract: An aircraft surface for use on composite structure. The detail surface includes a conductive foil, a conductive double pulled expanded screen, and an adhesive for joining the conductive foil and screen to a composite material. The conductive screen is layered between the conductive foil and composite structure, providing electrical contact between the foil and the composite structure.

Abstract: Disclosed is a method and apparatus for plating selected portions of a workpiece that cannot suitably be plated in dip-tank processes. The invention is particularly suitable for plating apertures in large parts. The aperture is enclosed between two containers, one on each side of the aperture. The containers are held in sealing position on the workpiece by means of an elongated rod that passes through both containers and through the aperture. Fastening means threaded onto each end of the rod engage container surfaces to urge the containers into sealing engagement with the workpiece, completely enclosing the aperture to be plated. An anode connected to a power source is mounted upon the elongated rod, preferably positioned substantially within the aperture. Application of a current with the workpiece connected to a cathode results in plating of the aperture.

Abstract: A safety and centering device for rotors suspended in contactless magnetic bearings, which provides almost instantaneous centering support for the rotor if the bearing magnets loose power. In a preferred embodiment, the rotor shaft has a collar with a conical friction surface, and a sleeve controlled by an electro magnet with counter-acting springs and also having a conical friction surface. In case of power failure the springs force the two surfaces together and provide centering support for the rotor. In another embodiment having a vertical rotor, the bearing magnets lift the rotor with the friction collar out of engagement with the matching stationary friction surface when the rotor is operating; but if the rotor bearings become de-energized the rotor drops with the collar falling into engagement with the matching friction surface.

Abstract: A method of electroplating chromium onto a metal article includes an electrolytic surface treatment step and a plating step. In the electrolytic surface treatment step the article is immersed in an alkaline solution of a cyanide salt and an electrical potential is applied to the article and reversed in polarity at predetermined intervals. The potential is preferably applied in alternating 15 second and 5 second intervals, the polarity of the potential applied to the article being positive during the 15 second intervals and negative during the 5 second intervals. A potential of between about 4 to 6 volts is preferred. The potential is applied to the article for a period of 3 to 15 minutes, preferably beginning and ending with a 15 second interval during which the polarity of the potential is positive. The article is then immersed while still wet in a chromic acid electroplating bath.
