Abstract: There is disclosed a packaging method, and package, for animal feed supplement blocks. The packaging method comprises pouring a chemically hardening feed supplement mixture into a mold lined with a bag formed of a water soluble plastic, preferably polyvinyl alcohol. The top edges of the plastic bag are folded against the surface of the liquid mixture in the mold, and an adhesively backed label can be applied over the folded edges. The mold is bottomless, so that it can be readily stripped after the supplement mixture has solidified into a block. The resultant package greatly increases the storage life of the block as it substantially reduces moisture loss and eliminates mold growth. The package is a very attractive, glossy surfaced product, and the color and appearance of the block can be observed through the glossy transparent plastic film. As the plastic film is water soluble and digestible, it does not present any hazard to cattle in the event it is eaten by the cattle.

Abstract: There is disclosed an improved power assisted wrenching tool for the attachment of fasteners in loose and interference fit applications, and particularly for use with frangible fasteners. The improvement comprises a readily removable key which is used to immobilize the bolt during attachment of a threaded fastener, typically in a loose fit application. The key is retained in a wrenching tool assembly by a detent ball which is positively locked in the center core of the holder member of the wrenching tool and can only be disengaged by the axial alignment of the holder and the socket drive members of this assembly. The tool is thus easily adaptable for the application of fasteners in either loose or interference fit applications.

Abstract: There is disclosed an improved spray tip particularly suited for airless pressured spraying utilizing a spray orifice member in a removable turret member that can be rotated to reverse the orifice for cleaning. The design permits rapid exchange of the turret member, permitting quick substitution of different sized orifice members. The turret member is sealed in the assembly with a thin plastic seal and a seal support which is compressed in the assembly by hand tightening. The seal and seal support are restrained in the spray tip against dislodgement during removal of the turret member. A tee seal is provided which has a flange of reduced diameter which seats against the end of the spray gun to insure complete sealing with hand tightening of the retainer nut. The spray tip also includes a low friction bearing washer between its housing and retaining nut which, in cooperation with the tee seal, permits rotation of the spray tip without loosening its retainer nut.

Abstract: There is disclosed a method for imparting a decorative or printed pattern to the surface of rotationally molded products during their manufacture. In this method, the decorative patterns are formed on a sheet film transfer as a coating of pigments dispersed in a hydrocarbon wax which overlays a release agent, such as a silicone coating on the sheet film. The decorative wax pattern is applied to a preselected area of an inside wall of the rotational molding cavity by positioning the transfer against the surface of the wall and burnishing the pattern onto the interior wall of the mold cavity. Thereafter, the particulate molding resin is charged to the cavity and the product is molded in a conventional procedure, resulting in transfer of the pattern as pigments incorporated into the resin, with most of the wax surfacing and being excluded from the product.

Abstract: There is disclosed an improved spray tip particularly suited for airless pressured spraying utilizing a spray orifice member in a removeable turret member that can be rotated to reverse the orifice for cleaning. The design overcomes difficulties with prior art spray tips of this construction by the use of a thin resilient seal which is located between the turret member and a seal support which is compressed in the assembly. The use of the thin seal achieves a fluid tight seal that prevents leaking even of low viscosity liquids while avoiding the seizure problems which have characterized plastic seals of prior devices. The turret member is removeable without disassembly of the spray tip or its guard, thereby permitting facile interchanging of turret members with differently sized orifices.

The flashlight switch is located in the end of the side-handle which, preferably, has an enlarged bulbous end for gripping purposes. In preferred embodiments the side-handle includes a central, rotatable sleeve with an interchangeable extension block to permit adjustment of the side-handle to varied hand widths.

Abstract: The invention is an adjustable spray nozzle useful in airless liquid spraying. The spray nozzle uses interchangeable spray orifice members which discharge against the beveled end of a cylindrical splash pin. The orifice member lines the cylindrical bore which receives the splash pin and the latter is axially adjustable in the spray nozzle body to permit an adjustably variable opening of the orifice, thereby permitting infinite adjustment of the volume of liquid and the area of the fan spray produced by the spray nozzle. The interchangeability of the orifice members provides a wide range of adjustability since interchangeable orifice members of varied orifice diameters can be readily substituted in the spray nozzle.1. Field of InventionThis invention relates to a spray nozzle and, in particular, relates to an adjustable spray nozzle useful in airless spraying of liquids such as paint.2.
