Abstract: An apparatus for efficiently removing VOC from a plurality of remotely located sources of VOC contaminated gas streams includes a plurality of liquid absorbers, each located near and communicating with a source of a VOC contaminated gas stream, the liquid absorbers associating the VOC with a scrubbing liquid. A gas conduit is associated with each liquid absorber to allow for the recycling of properly conditioned gas to the VOC source. A conduit is connected to each liquid absorber for conveying VOC laden scrubbing liquid from the liquid absorber to a separating apparatus in fluid communication with each of the conduits. A conduit recycles the scrubbing liquid from the separating apparatus to at least one of the plurality of liquid absorbers. A heat exchanger associated with the scrubbing liquid after separation transfers heat to the scrubbing liquid prior to separation, or to an HVAC system, or to the scrubbing liquid prior to the liquid absorber.

Abstract: An appartus for removing VOC from a plurality of remotely located sources of VOC contaminated gas streams includes a plurality of liquid absorbers, each located near and communicating with a source of a VOC contaminated gas stream, the liquid absorbers associating the VOC with a scrubbing liquid. A conduit is connected to each liquid absorber for conveying VOC laden scrubbing liquid from the liquid absorber to a separating apparatus in fluid communication with each of the conduits. The separating apparatus receives the VOC laden scrubbing liquid from the plurality of liquid absorbers and separates the VOC from the scrubbing liquid. A conduit recycles the scrubbing liquid from the separating apparatus to at least one of the plurality of liquid absorbers.

Abstract: A method for fabricating a split compressor case for a gas turbine engine is described which comprises the steps of assembling the two axial sections of the split case along corresponding flanges of the sections with a flat shim disposed between corresponding flanges and machining this first assembly to preselected contour, determining the degree of ovalization of the first assembly at the engine operating temperature as a function of axial extent of the assembly, assembling the two axial sections with a pair of tapered shims each having thickness which varies along the length and width thereof in correspondence with the determination of ovalization of the first assembly as a function of axial extent whereby ovalization is substantially eliminated at the engine operating temperature in an assembly of the axial sections and tapered shims.

Abstract: A fuel metering device of simple design is provided, utilizing a unique cing air supply mechanism for cooling the feul supply spraybar and fuel metering valve of an aircraft or afterburner, such a mechanism also functioning as a piston position control agent, which in turn controls the fuel supply rate of fuel injected into the combustor. The spraybar is filled with fuel under pressure at all times, and a leaky sleeve prevents potential coking fuel due to the high combustor temperatures. Additionally, the piston for actuating the fuel metering valve requires no gasket, as cooling air is passed about its periphery, and a pair of cooling air supply valves control the pressure differential across the opposite faces of the piston to in turn selectively position the pintle of the fuel injection valve to change the flow rate of fuel into the combustor.
