    Abstract: A fluidic oscillator capable of generating free fluid jets having distinctive, controllable and industrially/commercially useful flow patterns has a switching chamber having an inlet port that allows a pressurized fluid to enter and flow through the oscillator, an exhaust passage having a sidewall that forms one boundary wall of the switching chamber, a container passage having a sidewall that forms the second boundary wall of the switching chamber, a compliance member connected to the distal end of the container passage, and an expansion chamber connected to the distal end of the exhaust passage, with the expansion chamber having an exhaust orifice that allows fluid to flow from the oscillator. In operation, such an oscillator yields a contained fluid jet that issues from the inlet port into the swishing chamber and alternately switches its flow direction between the container and exhaust passages. This switching action serves to generate controllable pressure waves in the exhaust passage and expansion chamber which act to control the pattern of the free fluid jet that flows from the orifice.

    Abstract: Air is detected from opposing ends of a trough-like continuous contour which defines a guide path for the two opposing streams. The air streams will be attached to flow along the trough and where the oppositely directed streams impact or impinge upon each other, they will be deflected normal to their path and the two combined streams will be projected or directed perpendicularly outwardly from the trough in the form of a fan-shaped jet. By controlling the velocity of the two opposing jets, the point of impact or impingement of the two jets can be moved along the trough with the trough defining the path of movement of the point or virtual outlet of outward projection of the combined jets. In preferred embodiments, the defrost and heating and air conditioning outlets for automobiles incorporate the invention so as to avoid protrusions and provide a continuous clean and unbroken appearance.

    Abstract: There is disclosed an oscillating reed particularly for use in generating a sweeping or oscillating air flow pattern which is rendered clickless by limiting directions of bending of the reed element to an axis transverse to the direction of air flow. This significantly silences the oscillations and, in conjunction with polishing of the edges of the reed and rounding the corners of the mounting bar in which the downstream end of the reed is secured, cracking and breakage of the reed element has been substantially eliminated thereby lengthening significantly the life of the oscillating element.

    Abstract: A dual pattern nozzle comprises a fluid oscillator of the type which utilizes an obstacle or island in the path of liquid flow to produce a vortex street downstream of the island. A flow splitter is disposed downstream of and sufficiently close to the island to prevent the flow around the island from re-combining before reaching the flow divider, whereupon liquid vortices are alternately issued from each side of the divider. The spinning liquid breaks up into two patterns of droplets, the patterns being directed at respective spaced areas.
