Abstract: A nozzle assembly for filling containers such as toothpaste tubes comprises inner and outer tubular members providing a core column of one fluent paste material separated from an annular column of a second fluent paste material, with the inner tubular casing being slotted for admitting streams of the second paste material peripherally into and along the core column before discharge from the nozzle assembly, as to produce a striped effect in the discharged composite product.

Abstract: Apparatus for admixing a deodorizing liquid with a bad smelling liquid, comprises a hollow body in the form of a Y lying on its side in a vertical plane, the lower leg of the Y discharging the admixed liquids and the upper leg of the Y supporting and housing conduits for supplying the deodorizing liquid lengthwise of the body to dispensers therefor located adjacent the lower end of the body. A fixed shaft within the body has partitions secured thereto that are comprised by a plurality of blades and are oppositely inclined for initially mixing the two liquids. Above these partitions, a rotary helicoidal turbine is rotated by a turbine shaft that extends through the upper leg of the Y.

Abstract: A liquid sprayer for a gas turbine engine comprises a body formed with one or more air passages therein and one or more fuel passages. The fuel passages open into the air passages over portions thereof whose dimensions change smoothly and continuously longitudinally of the passage. Each air passage may be of rectangular cross-section over said portion with the cross-sectional shape thereof changing from one dimension being smaller than the other to said one dimension being greater than the other. The fuel passage opens into the air passage at a location at which the two dimensions are substantially the same.This liquid sprayer device promotes efficient mixing of the fuel with the air.
