Abstract: An apparatus and process for the electrostatic spraying of a mixture of a plurality of liquids, suitably liquids which react together rapidly to form a solid, liquids which are physically imcompatible, or liquids, such as paints, to provide novel optical effects. The apparatus includes a sprayhead formed with a plurality of channels which communicate with a common outlet means. The liquids are supplied to respective channels and meet at the outlet means. There they are subjected to an electrical field which causes a mixture of the liquids to be drawn from the sprayhead in the form of one or more filaments, the or each filament constaining a mixture of liquids in the proportions equal or substantially equal to the proportions in which the liquids were supplied to the sprayhead.

Abstract: An apparatus for spraying heated hot melt adhesive in elongated strands or fibers in a controlled, spiral pattern upon a substrate comprises a spray gun having a nozzle formed with an adhesive delivery passageway and an air delivery passageway both of which terminate at the base of the nozzle. A nozzle attachment in the form of an annular plate is mounted to the base of the nozzle by an end cap. The annular plate is formed with a throughbore which receives hot melt adhesive from the adhesive delivery passageway and ejects an adhesive bead through a nozzle tip formed on the plate. An annular groove formed in the plate facilitates the drilling of air jet bores therein at an angle relative to the throughbore and adhesive bead ejected therefrom.

Abstract: A method of and apparatus for burning liquid fuels such as oil or the like and/or solid fuels, especially coal, peat or the like, in pulverized form, the latter either in dry condition or mixed with a carrier liquid such as water and/or oil to form an emulsion being introduced together with the liquid fuel into a combustion chamber while creating a recirculating flow profile, said flow profile being confined by a rotating outer flow of air. For thorough breaking-up of the fuel introduced into the combustion chamber the fuel inlet is constituted by a plurality of inlet ports approximately evenly distributed along a circumference, especially a circle, the liquid-fuel inlet ports and the inlet ports for solid fuel or a fuel emulsion being alternately arranged along said circumference. The fuel inlet ports may be directed either radially and/or at an outward inclination in the direction of flow, based on the longitudinal axis of the combustion chamber.

Abstract: This improved ignition device for a moving grate type sintering machine is an inexpensive, compact combustion device which can form a strip of flame extending uniformly and continuously over the width of the strand. This ignition device can provide a uniform ignition intensity, and the ignition conditions of the raw mix can be controlled optimally by moving the burner and a hood therefor vertically and/or rotatably in accordance with the operational conditions of the sintering process. The ignition device thus contributes to prevent the sintered ore from being unevenly sintered, and to save heating energy.

Abstract: The present invention pertains to an oil atomizer suitable for use with a heavy liquid fuel which is constituted by a cylindrical body for delivery of the heavy liquid fuel to an atomization zone, spray tubes in the atomization zone arranged about the periphery of a conical cap terminating the cylindrical barrel and a shroud surrounding the cylindrical barrel and permitting passage therebetween and a shroud tip terminating the shroud and enclosing the cap, the spray tubes being inserted through openings in the shroud tip which permit passage of air or other fluid around the spray tubes.

Abstract: A body is provided with at least two cylindrical swirl chambers used to form a liquid spray cone for injecting charge gases resulting from charging coal to the coke oven, and a liquid spray cone for cleaning coke-oven gas passing through the coke oven ascension pipe. The swirl chambers are made of different diameters and each has a separate tangentially oriented inlet and a separate axially directed spray nozzle. The chambers communicate with one another through a by-pass passage to provide flow of liquid from one swirl chamber to another one.

Abstract: An elongated burner, which produces a stream of metal oxide soot, comprises three adjacent housings. A centrally disposed housing contains a linear array of orifices for issuing a gas-oxygen mixture to produce a linear flame. Disposed on opposite sides of the central housing are two housings having orifices for issuing into the flame two linear streams of metal halide vapor. Gaps between the central and outer housings permit air to be aspired for stabilizing the flame. Additional flame stabilization may be achieved by providing a shield along the entire perimeter of the halide vapor streams to prevent the random aspiration of air into the sides of the flame.

Abstract: Mechanical pressure exerted by a spring on the diaphragm of a pressure regulator is adjusted by an inclined cam surface on a linearly movable slide member.Flow of gases to a gas-fired torch is controlled by a valve which is operatively connected to an inclined cam surface on a linearly movable slide member.A gas-fired torch assembly has a housing, a tip base extending laterally of the housing and connected thereto for swivelling movement by a connector with male and female portions. A spring retainer clip on the exterior of the female portion extends through slots in the female portion and into a circumferential groove in the male portion. Upon separation of the connector elements, a safety cutoff valve closes the gas outlet of the housing.A burner tip base has a passage provided with a dust plug which prevents contaminants from entering the burner tip when it is detached from a torch assembly. In use, gas pressure moves the dust plug to a passage-opening position.

Abstract: A valve unit of a spraying apparatus employs two passageways each provided with an independent manually operated valve and leading respectively to a spray nozzle and a jet nozzle. By providing an interconnecting hole between the inlets of the two passageways and forming the passageways in different bore sizes, different proportions of liquids supplied to the two inlets may be selected as determined by which valve is operated. The unit is very useful for the washing and subsequent spraying of cows' udders with a bacteriacide.

Abstract: A gas-liquid contacting method and a scrubber used therefor are disclosed which are adapted to remove harmful components, such as SOx, NOx, CO, Cl.sub.2 and HCl contained in exhaust gases. According to this invention, liquid is sprayed to follow a conical form and the mist of liquid which is thus being diffused in a conical form is encompassed with a gas flowing in parallel relation therewith. To this end, at least one nozzle for spraying liquid and an encompassing tube for ejecting gas are arranged to specific forms and relations to the effect that an excellent contacting efficiency will result, without increasing energy consumption due to pressure loss.

Abstract: A jet aerator module for securing intimate contact and admixture between a liquid stream and an oxidizing gas including a housing constructed of sheet form material, a gas inlet in the housing for introducing a pressurized oxidizing gas into the housing, a liquid inlet in the housing axially spaced from the gas inlet for introducing liquid to be treated into the housing, an inner liquid carrying chamber composed of sheet form material disposed within the housing in spaced relation to the gas inlet, thereby providing a gas chamber between the chamber and the gas inlet, the housing being provided with angularly spaced relatively large diameter jet nozzles about its periphery, and the inner chamber being provided with smaller diameter jet nozzles about its periphery in axial registry with the relatively large diameter jet nozzles in the housing. The construction is such that the entire module is relatively lightweight and capable of being manufactured at low cost from readily available materials.

Abstract: A spray boom for aircraft involving an elongate reservoir having the exterior shape of an air foil designed to minimize drag and assist in the lifting of the aircraft. The reservoir is interiorly divided into a plurality of separate compartments, each of which is sealed from one another and each of which is capable of handling a different type of material such as liquids, powders, granules, or even gases, if so desired. These compartments extend the full length of the boom and each of the compartments is provided with its own discharge nozzle whereby the contents of each or any of the compartments can be individually discharged therefrom along the entire length of the boom so that the contents of each compartment can be sprayed across the entire spray pattern of the aircraft.
