Abstract: An explosion-proof conduit fitting configured to be placed between two pieces of electrical conduit, thereby connecting the two conduit pieces together such that electrical lines running through the two conduits also pass through the fitting. An embodiment utilizes two primary components to prevent migrations of gases and to provide the structural requirement of withstanding the extreme pressures of explosions from allowing flames and temperatures above the ignition temperature of flammable gases to pass through the hazardous area boundary: a granular fill, such as sand; and a removable gas-tight fire-stopping compound, such as an expanding closed cell foam.

Abstract: A combined water-wash and water injection cooling system for a gas turbine engine including a water delivery system, an air delivery system, and a controller configured to couple to the gas turbine engine, the water delivery system, and the air delivery system to access and execute one or more routines. The water delivery system includes one or more spray nozzles to spray water upstream and directly in front of a compressor of the gas turbine engine. The air delivery system is configured to provide air from the compressor to the water delivery system so that the one or more spray nozzles spray atomized water into the compressor of the gas turbine engine during a cooling mode to cool the compressor. During an on-line water wash mode, air from the air delivery system to the water delivery system is turned off to enable the one or more spray nozzles to spray non-atomized water into the compressor of the gas turbine engine to wash the compressor.

Abstract: A method of fluid processing a semiconductor workpiece, including disposing a workpiece holder with a housing capable of containing a fluid, the workpiece holder retaining the workpiece, providing an agitation system connected to the housing and comprising a member disposed within the housing adjacent the workpiece holder, and agitating the fluid by moving the member substantially parallel to a surface of the workpiece with a non-uniform oscillatory motion, the non-uniform oscillatory motion being a series of substantially continuous geometrically asymmetric oscillations wherein each consecutive oscillation of the series is geometrically asymmetric having at least two substantially continuous opposing strokes wherein reversal positions of each substantially continuous stroke of the substantially continuous asymmetric oscillation are disposed asymmetrically with respect to a center point of each immediately preceding substantially continuous stroke of the oscillation.

Abstract: Methods and apparatus for providing a high performance stringed instrument. In one embodiment, the stringed instrument comprises an electric guitar constructed entirely of sheet metal, with the body and neck permanently joined together to produce a one piece (unitary) style guitar construction. This method of construction results in improved overall consistency of the product. In particular, the construction utilizes a substantially homogenous material throughout the guitar and further includes a stronger, stiffer and straighter neck that allows for a more consistent sound than is possible using traditional manufacturing materials such as wood. Such a construction also offers improved sustain of string vibration, an attribute that is highly desirable to guitar players. The incorporation of a unique supporting structure into the headstock contributes to a unique warm timbre when played that has heretofore been unachievable in combination with improved sustain characteristics.

Abstract: A method and system for monitoring and controlling an injection operation is disclosed. A plurality of distributed fiber optic sensors is located in a production well. Fluid is injected into an injection well spaced apart from the production well. A parameter of a formation between the production well and the injection well is determined from measurements from the formation obtained using the fiber optic sensors. At least one of an injection of fluid into the injection well and a flow into the production well is controlled in response to the determined parameter.

Abstract: A method and apparatus for fluid sealing a workpiece retained by a workpiece holder are described. A pressure differential can be formed across a fluid seal to counteract fluid attempting to penetrate the fluid seal, which can contaminate the underside of the workpiece. The apparatus can include a ring forming a barrier to fluid entry with the workpiece and a source providing pressure to form the pressure differential. The pressure or the pressure differential can counteract hydroscopic fluid pressure or hydrostatic fluid pressure that is acting to force fluid through the barrier between the ring and the workpiece.
