Abstract: Foaming apparatus for foaming a water detergent mixture using compressed air comprises a housing having an elongated main bore extending therethrough. An upstream portion of the main bore is tapered in a generally downstream direction. A jet of water detergent mixture is delivered axially into the tapered portion of the main bore through a first orifice. Four second orifices extending transversely into the tapered portion deliver compressed air for mixing with and foaming the jet of water detergent mixture. Foamed water and detergent mixture is delivered through an outlet at the downstream end of the bore.

Abstract: In the spray head for the administration of a multi-component material by means of gas, a gas channel (2) with gas connection (3) is provided, which channel is divided by a separating web (4) into a plurality of channels (2a2b) running parallel to the separating web. Into these channels there open out boreholes (5, 5a) for receiving cannulas. The open ends of the boreholes (5, 5a) go into grooves (7, 7a) which serve for guiding the cannulas (6, 6a). The grooves are arranged parallel to the gas channel (2). The separating web (4) protrudes beyond the channel ends (9, 9a).

Abstract: The present invention relates to a replaceable insert adapted to fit within the atomization port of a spray nozzle used to atomize a gas/slurry mixture. The nozzle insert has a configuration which greatly minimizes the build-up of solids on the end of the insert, the forward face of the nozzle as well as around the atomization ports when atomizing a slurry. The improved features of the nozzle insert include (a) the interior fluid conveying passage has a constant diameter through the head of the insert; (b) the downstream end of the head is tapered and ends in a circular knife edge at the spray outlet; and (c) the tapered head extends outwardly from the forward face of the nozzle a distance sufficient for the spray outlet to be positioned beyond eddy currents which form during atomization of the gas/slurry mixture.

Abstract: A hydrotherapy method for discharging a water stream through a rigid conduit while concurrently translating the conduit discharge orifice along a nonlinear path describing an area. The conduit is comprised of a supply section and a discharge section having an axis misaligned with the supply section axis for discharging a stream in a direction tending to rotate the conduit around the supply section axis. Frictional loading of the conduit, attributable to suction produced by the supply water jet, is mitigated by providing a passageway which permits the suction to draw tub water into a cavity for entrainment by the water jet for discharge through the conduit.

Abstract: A nebulizer assembly particularly well adapted as a liquid chromatograph/mass spectrometer interface including a pair of nebulizer plates, a base, and a cap for tightly holding the nebulizer plates against the base. A first nebulizer plate has a centrally located outlet orifice and a radially extending groove, and the second plate has a centrally located gas inlet orifice and a radially displaced liquid inlet orifice. The gas inlet orifice aligns with the outlet orifice and an aperture provided in the cap, and the liquid inlet orifice aligns with a section of the groove provided in the first nebulizer plate. When the gas inlet orifice is coupled to a pressurized gas source and the liquid inlet orifice is coupled to a pressurized liquid source, uniform droplets having a diameter of approximately 10 microns can be formed from an outlet orifice twice that diameter.

Abstract: This invention relates to a nozzle assembly used to atomize liquids within air, particularly useful for coating die surfaces with die release lubricants. The atomizing nozzle includes an internal poppet valve element which is operated to control the flow of lubricant in response to a control air pressure signal. Blow air is initially transmitted to a pre-atomization area where some air is introduced in the lubricant which is thereafter introduced into the main blow air stream. This pre-atomization function has been found to enable fine atomization at low flow rates of lubricant. The pre-atomization bore further enables the device to be self-cleaning by clearing out the lubricant passage. Fine control over lubricant flow rate is provided by an elliptical shaped orifice which is closed off by the end of the poppet valve element.

Abstract: A gaseous fuel reactor is formed from a plurality of concentric casings which form a primary air chamber, a secondary air chamber, a combustion chamber, a gas distribution chamber, and a tertiary air chamber. The flow of gas and air through the various chambers interact to provide controlled flame characteristics. Additionally, the flame is maintained at a lower temperature to avoid the formation of pollutants.

Abstract: A bleach system for blending gaseous chlorine with a paper pulp slurry flow stream by mixing the chlorine with a larger quantity of steam prior to blending the chlorine/steam gas mixture with bleach washer filtrate which serves as carrier water for a multiplied number of gas bubbles entrained in the filtrate. As the cooler filtrate water extracts heat from the mixed gas bubble, the steam constituent condenses to collapse each bubble to a fraction of the original volume thereby providing a larger number of smaller chlorine bubbles than otherwise available from conventional phase mixing injectors.The mixed phase flow stream of chlorine and filtrate is thereafter blended with the pulp slurry flow stream by shear induced turbulence resulting from a greater injection velocity of the mixed phase stream into the center of the slower moving slurry stream.

Abstract: An improved mixing nozzle for a post-mix beverage dispenser having a water supply chamber co-axially surrounding a syrup supply port, has an elongate syrup diffuser having a spray head on its lower end, an upper water distribution disc on the diffuser having a plurality of apertures having a cumulative opening area for passage of water, a convex frusto-conical water spreader is directly below the upper disc, a lower water distribution disc is spaced below the upper disc and the spreader, the lower disc has a plurality of apertures and a clearance between itself and a nozzle spout, the cumulative area of the lower disc apertures and spout clearance is several times the area of the upper disc apertures, an enlarged water plenum is between the spreader and the lower disc, and the syrup diffuser has outlets to spray syrup into a water stream below the lower disc.

Abstract: An improved fuel oil atomizer which comprises a burner tube through which fuel oil is supplied under selected pressure, and a coaxial surrounding steam tube providing an annular space therebetween, the flow of steam being under greater pressure than the oil pressure. A burner head is joined to the burner oil tube through an orifice of selected diameter. The burner head has a long axial bore of constant selected diameter, which leads to the burner tip, which has a plurality of tip ports. There are a number of transverse ports between the annular steam path and the central bore, so that the steam can flow under pressure into the central bore of the burner head to mix thoroughly with the pressurized oil flowing from the orifice. Two factors are important in the construction of the burner head, namely that the central bore must be of constant diameter from the point where the steam and oil mix, outwardly toward the burner tip ports.

Abstract: This invention provides a burner head that may be used for the discharge of a mixture of steam and oil. Steam bores 10 penetrate the head from one end to the other. Oil ducts 11 lead to each bore 10 from one end of the head. One or more further ducts 13 lead from the rear end of the head to a chamber 2,20 formed at the front end of the head and additional oil ducts 12 lead back from the chamber to discharge one into each of the bores 10. The two ducts 11 and 12 that discharge into any bore are directed towards each other.

Abstract: When explosive gases are introduced into a combustion chamber care must be taken that no pre-ignition occurs. To this end, the gas is spatially subdivided into discrete volume elements, for example by means of a bundle of tubes having an internal diameter which does not exceed twice the quenching distance of the explosive gases. Such a division ensures that the wall distances of the gas portions of one volume element are greater than their quenching distances.

Abstract: A snow-making nozzle assembly which is very effective in producing uniform, small, highly atomized droplets of liquid that freeze to form snow is disclosed. The nozzle assembly in accordance with the present invention is comprised generally of opposed pairs of water outlets spaced at the periphery of a generally fan-shaped convergent-divergent compressed air nozzle. The water streams emitted from the water outputs impinge on each other and atomize substantially without contacting the walls of the nozzle. These liquid particles are entrained in the compressed air stream for further atomization and for distribution into the ambient air. The use of the nozzle in accordance with the present invention results in greatly improved snow-making capabilities when compared with prior art devices.
