Abstract: A spray assembly for a milk tank, where there is an elongate water pipe positioned in the tank, and a plurality of spray nozzle assemblies mounted to the pipe. Each spray nozzle assembly comprises a nozzle member having radially inwardly directed openings leading to a middle impact chamber which in turn leads directly to an upper discharge opening. The water flows radially inwardly to the impact chamber to provide a random expanding spray pattern that washes upwardly against the interior surface of the tank. The nozzle member is retained by a member having an expanded head and a shank that extends downwardly through a second opening in the pipe. A releasable retaining member retains the connecting member in place. In operation, the water flows against substantially all of the surface portions of the nozzle assembly to provide a self-cleaning action. The assembly can be easily disassembled for maintenance or possibly further cleaning.

Abstract: An ultrahigh pressure water apparatus converts feed water of normal pressure into ultrahigh pressure water by means of an ultrahigh pressure pump and projects the ultrahigh pressure water through a nozzle gun in the form of jets of ultrahigh pressure water. The nozzle gun has an eccentric shaft tube rotatably disposed inside a nozzle cover, a high pressure hose rotatably inserted into the eccentric shaft tube, and nozzles fastened to the leading end of the high pressure hose. Owing to the rotation of the eccentric shaft tube, the jets of ultrahigh pressure water projected through the nozzle are sympathetically rotated.

Abstract: A vapor-air humidifier for air climatizing or conditioning installations is disclosed which comprises a double-wall vapor distributor pipe defining vapor exhaust pipe means. By means of a jacket chamber or space, heated by the vapor or steam, the internal space or chamber of the vapor-air humidifier remains free of condensate due to cooling of the air current. The vapor transfered to the air current is thus removed from the internal space which is free of condensate and there is prevented any spraying of water of condensation. Since vapor exhaust elements are arranged along the exhaust pipe means and are distributed over the entire channel cross-section of the humidifier, there is avoided the formation of vapor layers.

The flow regulator includes a flow controller element disposed in a regulating chamber, biased in one direction by a metallic spring and urged in the opposite direction by supply pressure. The controller element cooperates with an outlet passage in the regulating chamber to form a variable orifice, reducing the effective area of the outlet in response to increased supply pressure. A retainer screen keeps the flow controller and biasing spring in place while serving as a protective filter.

Abstract: A burner for burning a mixture of a combustible gas and air including a curved wall member provided with a multiplicity of ports distributed throughout a substantial area of the wall. The ports are arranged in an ordered pattern such that every port, with the exception of a few along the edges of the burner, is surrounded by a plurality of closely adjacent ports. The size of each port and the distance between adjacent port edges are such that the jets of the gas-air mixture which issue from the ports merge into a common body of such mixture and form a closed lower pressure pocket around each port below such common body. The outer edges of such pocket are located above the minimum ignition level of each port and below the normal outer flame reach distance of the burner for the gas-air mixture supplied to the burner. As a result the flame produced by the burner may be stabilized in either of two regimes or in a combination of both depending upon the rate at which the mixture is supplied to the burner.
