Abstract: The present invention provides a novel process of recovering unreacted ammonia from a reactor effluent. This novel process includes at least the following steps: (1) quenching a reactor effluent containing ammonia with a first aqueous ammonium phosphate quench solution, wherein the pH of the solution is less than about 3.5, thereby absorbing ammonia to form a second aqueous ammonium phosphate solution richer in ammonium (NH4+) ions than the first solution but substantially free of dissolved CO2, (2) heating the second solution to an elevated temperature to reduce the amount of ammonium ions present to substantially the same level present in the first solution and thereby generate a vaporous stream containing ammonia, (3) recycling said vaporous stream containing ammonia to a reaction zone in a manner that minimizes the contamination of the reaction zone.

Abstract: A fishing lure holding device that includes a device housing and a plurality of multiple lure eye gripping mechanisms secured to an upper surface of the device housing in a manner to form a number of eye receiving channels between adjacent lure eye gripping mechanisms, the eye receiving channels each being of sufficient size to receive therein the eyelet end of a fishing lure; the device housing having at least one hook barb receiving compartment formed therein and a plurality of elongated hook barb passage apertures formed through an upper surface thereof, the plurality of elongated hook barb passage apertures being arranged into multiple rows of elongated hook barb passage apertures, each of the multiple rows being aligned with one of the number of eye receiving channels, each of the plurality of elongated hook barb passage apertures being in connection with a hook barb receiving compartment; each of the multiple lure eye gripping mechanisms including a spring biased eye locking pin that extends into the ey

Abstract: An inspection apparatus and associated method includes a sensor housing defining an internal cavity in which a sensor is at least partially disposed for inspecting the surface of a structural part and for detecting defects in the surface and the substructure of the part. The inspection apparatus includes a plurality of compliant fibers extending outwardly from a first end of the sensor housing and circumferentially about an opening defined by the first end of the sensor housing. The compliant fibers support the sensor housing above the surface of the part and maintain the sensor in a predetermined position relative to the surface of the part. The plurality of compliant fibers are adapted to flex laterally to accommodate obstructions on the surface of the part, such as raised fasteners, doublers or lap joints while maintaining the sensor in the predetermined position relative to the surface of the part.

Abstract: A nozzle is adapted to receive an ultrasonic transducer. The nozzle includes a cylindrical plenum chamber. An annular passageway circumscribes the plenum chamber. A porous material forms the annular walls of the plenum chamber and separates the plenum chamber from the passageway. The plenum chamber fluidly communicates with the passageway through the porous material. The passageway fluidly communicates with a supply line that, in turn, fluidly communicates with a pump that supplies water. The plenum chamber has a circular exhaust orifice for the exhaust of water from the nozzle. The plenum chamber contains an unobstructed forming space to facilitate the forming of ultrasonic waves. The diameter of the plenum chamber divided by the diameter of the exhaust orifice is a quotient of at least three.
