    摘要： For achieving a shut-off function, a mainstream communicates with a control stream into which an outlet for the mainstream opens laterally. By reciprocating the control stream back and forth across the outlet, for example by alternate pressurisation of reservoirs to which the control stream is connected at its ends, access of the mainstream to the outlet is inhibited. When the reciprocation is discontinued full flow of the mainstream to or through the outlet can take place.

    摘要： A fluidic flow control device comprising at least two generally aligned members having tapering bores therethrough, the members being so arranged as to constitute a convergence followed by a gradual divergence, separated by a gap, the gap communicating with an inlet/outlet or feed port. A cage connects the adjacent ends of the members and forms said port. A system for pumping may incorporate the device between a cylinder charged with pressure gas and an out-feed pipe. In operation, fluid is alternatively drawn in through the gap and into the cylinder and then pumped out by the gas across the gap and into and through the out-feed pipe. A level detector in the cylinder controls the oscillation of the system and an accumulator may be provided to smooth the outflow. Substantially continuous flow may be provided by coupling two systems to a common out-feed pipe. A pumped flow circuit useful for heat transfer utilizes two alternately operating devices out-feeding to a single diffuser section with connected feedback passages resupplying the devices in turn.

    摘要翻译： 流体流量控制装置包括至少两个大致对准的构件，其具有穿过其中的锥形孔，该构件被布置成构成会聚，然后逐渐发散，间隔开，该间隙与入口/出口或进料口连通。 笼连接构件的相邻端并形成所述端口。 用于泵送的系统可以将装置结合在装有压力气体的气瓶和出料管之间。 在操作中，流体交替地通过间隙被吸入到气缸中，然后通过气体被泵出通过间隙并进入并通过出料管。 气缸中的电平检测器控制系统的振荡，并且可以提供蓄能器以平滑流出。 可以通过将两个系统连接到共同的输出管来提供基本上连续的流动。 用于热传递的泵送流动回路利用两个交替操作的装置向外馈送到单个扩散器部分，其中连接的反馈通道依次再供给装置。

    摘要： In a fluid system, an in-line vented jet is disclosed whose vent is controlled by a vortex valve. Since the control ports of the vortex valve are coupled to a constant upstream pressure any variance in downstream impedance effecting said vent cavity pressure is immediately counter-acted by the vortex valve which acts as a rough pressure regulator for the vented jet cavity, thus maintaining constant pressure recovery regardless of downstream flow changes.

    摘要： Air is caused to simultaneously enter an inner nozzle in which a cylindrical plug is centrally located to form an annular orifice, and an outer nozzle in which fluid resistors are located to limit the maximum fluid pressure therein. The air discharging from the outer nozzle interferes with the air emanating from the annular orifice until such time as the fluid pressure from the latter is greater than that from the former. After that time, the air discharging from the annular orifice impinges directly on the edge of a resonating cavity producing a multiple frequency edgetone. The column of air in the resonating cavity is thereby caused to vibrate at a frequency determined by the depth of the cavity. The changes in pressure within the resonating cavity cause a diaphragm forming an end of the cavity to pulsate inwardly and outwardly. A rod is attached to the diaphragm, and this rod transmits the vibrations of the diaphragm to a metallic reed which will then oscillate between a pair of magnetic pole pieces. The oscillations of the reed will induce an electromotive force in a coil. The electromotive force induced in the coil may be made available to provide energy to operate an external electrical circuit.
