Abstract: An injector for a gas turbine combustion chamber, includes a fluid feed system; an injector body extending along a longitudinal axis; an injection head arranged on the injector body and configured to spray the fluid in a direction that is inclined relative to the longitudinal axis; and an actuator configured to turn the injector selectively about the longitudinal axis so as to vary the direction in which the fluid is sprayed; wherein the actuator is configured to enable the orientation of the injector to be varied by turning about the longitudinal axis through an amplitude less than or equal to 90°.

Abstract: A rotary atomizing head (4) is mounted on a fore end side of a motor (3). A shaping air ring (9) having a plurality of air outlet holes (10) at fixed intervals is provided on a rear side of the rotary atomizing head (4). Outer surfaces of the air motor (3) and outer surfaces of the shaping air ring (9) are enshrouded over the entire circumference by a cover member (7) formed of an electrically insulating material. An external electrode assembly (13) is provided radially outwardly of the cover member (7). An annular projecting portion (16) which projects forward is provided on the shaping air ring (9) over the entire circumference. The air outlet holes (10) are open in a fore distal end of this annular projecting portion (16). As a result, a corona discharge can be generated by allowing an electric field to be concentrated at the fore distal end of the annular protecting portion (16).

Abstract: Systems for dispensing heated liquids, such as hot melt adhesives, with the assistance of process air. The dispensing system may include a control operative to independently control a characteristic of the process air dispensed by a first dispensing module compared to the same characteristic of the process air dispensed by a second dispensing module.

Abstract: A radially-extending arm is adapted to rotate within a stream of first fluid flowing thereacross. In one embodiment, the arm comprises a plurality of lands located at different radial distances from the axis of rotation, and a port located on each land is operatively coupled to a source of a second fluid. The second fluid is sprayed from the rotating arm into the stream of first fluid that flows across the lands, and is thereby atomized. In another embodiment, the arm comprises a land stepped into the trailing edge thereof, and a port for injecting the second fluid is located on the land. In another embodiment, the land comprises a groove located between the port and an associated riser surface stepped into the trailing edge. In another embodiment, the arm comprises a port in the trailing edge thereof from which the second fluid is injected, and a groove is located on the trailing edge in a radially increasing direction from the port.

Abstract: A combustion heater comprising an induction chamber provided with an inlet, a combustion chamber in fluid communication with the inlet of the induction chamber, means for moving an oxydizer from the inlet of the induction chamber to the combustion chamber, a fuel reservoir, a frame defining a fuel passageway, means for moving a fuel from the fuel reservoir through the fuel passageway to the combustion chamber, means in fluid communication with the fuel passageway for shearing a fuel prior to combustion, means in fluid communication with the fuel passageway for heating the fuel prior to combustion, and means for combusting a fuel oxydizer mixture within the combustion chamber.

Abstract: A centrifugal humidifier having a rotatable body for propelling water outwardly on to an impingement surface that brake up the propelled water into droplets which are then entrained in a stream of air and discharged to the surroundings, wherein the impingement surface has a multiplicity of sawtooth ridges oriented with the more gradually inclined sides facing toward the direction from which the water is propelled by the rotatable body which promotes breaking up the water into finer droplets.
