Abstract: A fluid mixing device includes a nozzle having a first element mounted therein, and connected to a hollow, tubular element having a series of openings formed therein adjacent the first element. The hollow, tubular element extends outwardly from the nozzle, through an exit opening and may have a second element mounted thereon. The second element may take various shapes, including having a number of protrusions thereon, to vary the atomization of fluid flowing from the nozzle exit. An outer end of the hollow, tubular element may be free to suck in atmosphere, or may be attached to a tube immersed in a container, to draw in a second fluid to mix with the first fluid through the nozzle.

Abstract: This invention relates to a device for forming a mist or fog having a convex surface which receives and expands a fluid delivered thereto. The convex surface of the device has a number of circular protrusions spaced peripherally thereon, separated by a number of slots having holes therein. The holes communicate with an inner cylindrical chamber. Suction is produced through the holes when the fluid stream passes over them, to automatically add a further fluid to the fluid being expanded by the device. A cylindrical sleeve surrounds and protects the device. The device is supported in the cylindrical sleeve, either in front of a nozzle by an annular structure, or by a bent tube held in the cylindrical sleeve in front of the device, or in a venturi.

Abstract: The invention relates to a fluid nozzle wherein the formation of eddy currents is reduced to a minimum in the area of laminar flow and the velocity of the fluid is increased to a maximum. This is accomplished by the use of a convergent nozzle wherein the fluid is accelerated and pressure is decreased, then directed over an atomizing body having a convex outer surface where the fluid is allowed to expand and increase its velocity with a further reduction in pressure. Protrusions in the form of a plate or other projections extend from the surface of the convex outer surface to produce fluid flow detachment, separation and high velocity fluid spraying. Adjustment means are provided whereby the axial distance between the nozzle orifice and the atomizing body can be varied according to the desired fluid flow patterns.

Abstract: An elongated arm, pivotally mounted at the center to a support structure, includes a large, bulbous reservoir attached at either end thereof. The arm is hollow and a passageway therethrough joins the two reservoirs. A volatile fluid which vaporizes at a relatively low temperature (125.degree. F. or less) is placed within the reservoir/passageway to provide the activating fluid for the device. A source of heat input is provided in heat exchange relationship with each reservoir when pivoted to its lowermost point, causing the volatile liquid to vaporize and flow to the other end where it condenses, causing the other end to lower. An electrical generator or other energy converter is operatively associated with and operated responsively to the movement of the arm.
