    摘要: The fluidic oscillator consists of a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance. The inertance is a conduit interconnecting two locations of a chamber on each side of a working fluid jet issuing into one end of the chamber, the inertance conduit serving to transfer working fluid between the two locations. Through one or more output orifices located approximately at the opposite end of the chamber, the fluid exits from a chamber exit region which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid. The flow pattern in the chamber and particularly the vortex in the chamber exit region provide flow aspiration on one side and surplus of flow on the opposite side of the chamber, which effects accelerate and respectively decelerate the fluid in the inertance conduit such as to cause reversal of the vortex after a time delay given by the inertance. The vortex in the chamber exit region will thus cyclically alternate in the velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream our spray pattern whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector as well as the dynamic pressure component, both directed radially from the vortex. By changing these parameters by suitable design measures and operating conditions and by appropriately configuring the oscillator, sweep angle, oscillation frequency, distribution, outflow velocity, break up into droplets, etc. can be readily controlled over large ranges.

    摘要: In a clothes washer, liquid pulses are delivered to a bucket or tank of water to create continuously re-circulating flow therein in a vertical plane. The flow carries the clothes in a tumbling action and the pulses agitate the clothes passing the pulse source. Air is introduced into the water pulses and forms air bubbles in the tank which attract dirt particles and carry them to the surface where they are removed as part of a continuous surface overflow. In a preferred embodiment the liquid pulses are delivered by a novel fluidic oscillator of the feedback type in which air is continuously entrained by the power stream from each feedback passage in alternation.

    摘要: A dispensing pump is characterized by an elastomer bulb configured as a cup and having a tubular neck portion extending from its base. The cup portion is inverted in a pump housing with the neck extending upwardly from the center of the cup base into a stem member where it concentrically and resiliently engages a nipple. The rim of the cup portion is positioned to overlie a dip tube inlet into the housing. In its quiescent position the bulb is slightly longitudinally compressed by forcing the stem, neck and center of the cup portion into the bulb chamber, thereby forming a convolution at the periphery of the cup base. The convolution provides a positive seal of a vent passage which is open only during pump actuation. Actuation is effected by pushing the stem further into the cup, which action is aided by a spring snapping effect in the bulb, thereby forcing fluid from the pump chamber up through the neck and around the nipple. Relaxation of the stem permits the spring action to restore the bulb to its quiescent state while the cup rim is drawn into the chamber to unblock the dip tube and draw fluid into the chamber.

    摘要: The invention relates to conveyor apparatus, particularly for use in conveying large quantities of heavy bulky and/or dry materials over a long distance. Moreover, the apparatus of the invention may be constructed in out-of-the-way areas over deteriorated or difficult courses, such as rubble. This is achieved by the use of a tube-like elongated passage through which a plurality of joined conveyor cars pass. The elongated passage has openings in the bottom for receiving therealong spaced apart primary windings for a linear electric motor. The cars, in turn, have mounted in the bottom surface thereof the secondary of the motor. The apparatus includes air vents for accommodating air movements ahead of and behind the cars switching arrangements and provision for loading and unloading.

    摘要: A method is disclosed for assembling fluidic spray devices wherein a fluidic element formed on the surface of a body member is expeditiously sealed to form the device. The essence of the invention is the injection molding of plastic around or through the body and a cover plate, or into a prefabricated housing into which the body member is inserted, to preload the parts and force them into a permanent sealed assembly. In one embodiment the preloading is achieved by shrinkage tension of injected plastic material surrounding or penetrating the parts. In a second embodiment the preloading is achieved by injecting plastic material into a gap or gaps in a product housing containing the body member so as to force the element surface against a sealing surface.

    摘要: A fluidic oscillator flowmeter employs a fluidic oscillator wherein the frequency is proportional to flow through the oscillator. The oscillating flow is divided into two discrete paths, facilitating the counting of the frequency and the transduction of the frequency into a flow measurement indication. In one embodiment the flowmeter may be inserted into a large flow stream, wherein it utilizes only a small portion of the measured flow and presents a streamlined profile to the flow to minimize pressure losses. Alternatively, the entire measured flow may be passed through the flowmeter.

    摘要: A transportation threat detection system includes a communication module that receives an inertial event report from a reporting vehicle. The report includes (i) an indication of an inertial event from an inertial sensor at the reporting vehicle, and (ii) an indication of a geographic location associated with the event. The system also includes a fusion processor that associates the inertial event report with a potential transportation threat, consistent with the inertial event report and at the geographic location. The fusion processor generates a measure of support for the transportation threat potentially existing at the geographic location based on a participation rate generated using any additional inertial event reports received from respective additional reporting vehicles. The system also includes a reporting interface that renders output indicative of the potential transportation threat, wherein the output is made as a function of the generated measure of support.
