Abstract: An arrangement for separating a fluid from admixtures has at least a first and a second separation unit. The separation units are of the type using an increased pressure or pressure difference for their function and have improved performance with increased pressure. The second separation unit is supplied with the fluid by a pressurising pump device. The first separation unit furnishes fluid of reduced concentration of admixtures to the pressurising pump device. It is supplied with supply fluid having reduced, the same, or elevated concentration of admixtures, preferably either taken directly from an outlet of the pump device or from an outlet of the second separation unit for fluid of increased concentration of admixtures. Overall, the concentration of admixtures in the fluid supplied to the second separation unit is decreased, leading to an increase in overall performance.

Abstract: A diffuser comprises a conduit having a cross-sectional area that increases in a direction fluid flow. In one embodiment, the diffuser is used to reduce the incidence and severity of flow fluctuations that occur in an electrostatic deposition apparatus. In some embodiments, the diffuser includes one or more flow control features. A first flow-control feature comprises one or more appropriately-shaped annular slits through which fluid having a greater momentum than a primary fluid moving through the diffuser is injected into the “boundary layer” near the wall of the diffuser. A second flow control feature comprises one or more annular slits or, alternatively, slots or holes that are disposed at appropriate locations around the circumference of the diffuser through which a portion of fluid flowing in the boundary layer is removed. Boundary-layer flow removal is effected, in one embodiment, by creating a pressure differential across such annular slit or slots. Among other benefits, such flow control features reduce any tendencies for flow separation of the primary fluid in the diffuser.

Abstract: A fluid amplifier for sensing the level of a liquid in a reservoir, storage tank or other container and for generating a differential in pressure signal in response to the static presence of the liquid level at a predetermined level. An inlet develops a liquid flow stream. A first passage of major cross-sectional dimensions is provided for delivering a major portion of the flow stream to the reservoir or storage tank. A second passage of minor cross-sectional dimensions is spaced laterally of the first passage for developing a small signal fluid power stream substantially parallel to the major supply stream. A sensor is responsive to the static presence of the liquid level at the predetermined level for altering the smaller fluid power stream from its substantially parallel flow condition to a condition in which it diverts and attaches to the major supply stream. A signal developing device is provided for receiving a fluid pressure signal of one magnitude when the fluid power stream is parallel to the major supply stream and of a second magnitude when the fluid power stream is diverted.

Abstract: A main valve and separate sensing means are mounted in a housing spaced-apart relation. The main valve is formed with a valve chamber having an inlet port and an outlet port, and the valve comprises a valve seat and a valve member cooperating therewith. The valve member is movable between a closed position in which it engages the seat and blocks flow of fluid from the inlet to the outlet and an open position in which it is spaced apart from the seat and enables such flow. The sensing means includes an exhaust to the atmosphere and exhaust shutoff means actuable for closing the exhaust. The housing and main valve are formed with a passage enabling restricted leakage of fluid from the main chamber to the sensing means for exhaust to the atmosphere when the valve member is in the closed position. The leakage fluid is in communication with the valve member and when pressurized applies a force urging the valve member to the open position. The net cross-sectional area of the valve member exposed to the leakage fluid exceeds the cross-sectional area of the valve member exposed to the fluid in the main chamber. Introduction of pressurized fluid into the main chamber coupled with actuation of the exhaust shutoff means therefore builds up the pressure of the leakage fluid and opens the main valve.

Abstract: Exhaust gas is recirculated to an intake manifold of an engine by a shut-off valve and a fluidic amplifier for modulation in accordance with different engine parameters. The shut-off valve is normally biased to a closed position and it is opened to permit recirculation in response to a signal received from a fluidic NOR gate which operates in accordance with position of a carburetor throttle, engine speed and engine temperature. The fluidic amplifier includes a power jet chamber receiving a supply of exhaust and a vent chamber in fluid communication with a venturi disposed in the exhaust manifold, a receiver chamber and a pair of control jets. One of the control jets may be in fluid communication with the intake manifold or with a carburetor venturi. The other control jet may be open to atmospheric pressure compensated for the effect of changes in air density or engine speed.

Abstract: A system for drying and/or transporting particulate material, including fluidizing the material by means of pulsed air flow in jets which oscillate parallel to the path of motion of a bed of the material in an assymetric sweeping fashion which applies a net transporting force in one sense or direction, or by applying such pulsed flow so that the net force in either sense is zero, to cause drying without transport. The system utilizes phase locked acoustic oscillators to provide sweeping jets of fluid moving in opposite directions for drying and in the same direction for transporting the particulate material. The fluid oscillators are fabricated from 2 groups of molded or extruded members with the members of each group being identical. Spacers are employed to position the parts whereby to provide the desired oscillator configuration.
