Abstract: Methods are provided by which a treatment fluid (e.g., a liquid corrosion inhibitor) may be applied onto the interior surfaces of an aircraft fuselage. The methods include (a) deploying an automated guided vehicle (AGV) comprising a carriage assembly and a robotic spray system carried by the carriage assembly within the interior of the fuselage, (b) closing the cabin door opening of the fuselage with the AGV positioned therewithin, and (c) operating the AGV so as to move within the fuselage along a longitudinal axis thereof to spray the treatment fluid onto the surfaces thereof.

Abstract: A discreet mirrored cabinet is disclosed. Items can be secured inside by a locking mechanism, and security is enhanced by concealing the locked cabinet behind a mirror. The cabinet may include additional features such as an automated camera for capturing images when items are added or removed from the cabinet, and electric power can be provided to, for example, charge electronic device while they are securely stored in the locked cabinet.

Abstract: An apparatus in a steam generator that employs tube support plates within a shroud that is in turn disposed within a shell. The tube support plates are made of a material having a coefficient of thermal expansion lower than that of the shroud. The tube support plates are aligned during fabrication with minimal clearances between components. Using a tube support displacement system, a controlled misalignment is imposed on one or more tube support plates as the steam generator heats up. The tube support plate displacement system has only two parts, a spring bar and a push rod, that are internal to the steam generator shell and threadably engaged, thereby minimizing the potential of loose parts. The tube support plate displacement system can be used to provide controlled misalignments on one or more tube support plates, with one or more apparatus being provided for any individual tube support plate.

Abstract: Generally, an application provider can use their understanding of the general problem domain to design an application that covers the majority of the functionality that is required by application users, e.g., the types and quantities of data that are required by an application and which are typically gathered and stored. By configuring the application with flexible data structures which can be mapped to a variety of different types of data by the application user, the application can be customized by the application user to meet his or her specific needs. When the application user wants to expand the data set that is stored by the application beyond what the application provider has provided, they can make use of a management interface to add mappings for custom attributes to the flexible data structures. The application users are not required to write any additional code or modify the application directly.

Abstract: A compact, low-profile, in-line beveling tool suitable for use in a confined space, such as a tightly packed array of tubes. The tool is inserted within a workpiece via a feeding mechanism, such as a worm gear arrangement, and is secured to the workpiece via an internal expanding mandrel assembly. A motor drives cutting inserts, mounted on a beveling head, in rotational motion to bevel the workpiece. The motor and beveling head with cutter inserts all share the same axis. A gear reduction box, located between and operatively connected with the motor and beveling head, provides the low RPM and high torque needed to make practical use of carbide insert technology. In one embodiment, the motor is a hollow core air motor having vanes symmetrically arranged about the axis.

Abstract: A removable debris shield and method to internally protect a portion of a vessel, such as a pressure vessel, during fabrication. Pliant material sufficient to span a desired interior portion of the vessel has a hem located around the periphery of the material and having at least one opening. A hoop is removably inserted through the opening into the hem to extend the material across the desired interior portion of the vessel. In one embodiment, a spreader bolt spreads the hoop to force it tightly against the walls of the vessel.

Abstract: A hydraulic expansion mandrel for expanding tubes in a heat exchanger tube bundle into a tubesheet is formed from a non-metallic material, such a carbon fiber-reinforced material. The mandrel includes an elongated cylinder having a tip, a fluid supply end and a reduced diameter section. A pair of O-rings separates the reduced diameter section from the tip and fluid supply end of the elongated cylinder. An adjustment shim, located between a threaded collar and a locking stop collar, adjusts the length of the mandrel inserted into a tube.

Abstract: The invention provides a lightweight, temperature-resistant debris shield suitable for used within a closed vessel. The invention has no small parts, and can be readily assembled and disassembled in a confined space without tools after passing through a tight passage such as a pressure vessel manway.
