A method of making a package for displaying articles for sale. The method includes positioning a die over a porous or perforated backing card and a transparent plastic cover film over the die and card. A vacuum is then applied to the underside of the card so as to bond the film to the face of the card. The die is then removed to expose a pocket that receives the article or articles to be displayed. The portion of the film adjacent the open end of the pocket may be heat sealed to the card or alte...

A method of making a sleeved garment on a knitting machine, the method including the steps of knitting a shoulder portion of each sleeve, in the direction towards the upper end of the sleeve, in reciprocatory manner on both beds of a pair of opposed beds of the machine, so that the pieces of fabric of each shoulder portion on opposite beds are continuous at the edge of the shoulder portion outermost on the machine and in the finished garment, knitting the body of the garment commencing at the lo...

A method of packaging steel and other articles wherein the articles to be packaged are first enclosed in a flexible sheet of material such as polyethylene and are then encapsulated in a cellular plastic sheath in a mold by placing a liquid foamable reaction mixture in the mold under confinement and at resulting conditions of elevated temperature and pressure. The flexible sheet enclosure is vented to atmosphere through the mold wall so that, as the foamable reaction mixture expands in the mold, ...

Images are formed on direct positive photographic material in a single white-light exposure through the use of a master sheet which consists essentially of a selectively transmissive filter layer which allows transmission only of longer wave length light which is effective in reversing the prefogged direct positive material, and indicia disposed with respect to the filter layer to form in the master substantially totally opaque elements and substantially totally white light transmissive elements...

An improved method of fracturing an underground fluid bearing formation penetrated by a well bore for the production of fluids therefrom by injecting a composition capable of forming a fluid permeable barrier in said formation at a pressure sufficient to form fissures therein extending from said well bore, and thereafter maintaining pressure on the composition for a predetermined period to permit the composition to set and form a fluid permeable barrier in the formed fissures.

A tubular aluminum member is extruded in a rectangular shape and cut to a given length. The four walls of the tubular member are successively cut by a circular saw to form a portion of the tubular member into a generally spiral shape winding with terminal portions at each end. The member is treated to form an insulating layer on the surfaces of the member including the facing sides of the winding to form an inductive winding for passing current. The winding may be compressed and one set of edges...

An improved water treating composition comprising about 45 to 85 percent alkali metal hexametaphosphate, about 5 to 35 percent alkali metal pyrophosphate, and about 3 to 30 percent di-alkali metal orthophosphate. The preferred composition is a 70-20-10 composition, containing 70 percent sodium hexametaphosphate, about 20 percent sodium hydrogen pyrophosphate, and about 10 percent dipotassium orthophosphate. The invention also provides a method for treating water which comprises adding the forego...

A method of waterflooding a formation with a flood water and surfactant mixture whereby gel particles are added to the injection mixture to improve the efficiency of the flood.

Application of resinous organic coatings onto non-conductive surfaces by electrodeposition is accomplished by first applying on the surface a layer of conductive particles in a carrier and then employing the surface as an electrode in an electrodeposition coating process to deposit a resinous coating on the surface. Carbon or metal particles can be used in the conductive layer and any electrodepositable resinous film-forming coating composition can be utilized in the process.

Metallic members consisting essentially of copper or copper alloy, low carbon steel, stainless steel, nickel or nickel alloy, or any combination thereof, are joined together by initially coating the members to be joined with a thin layer of nickel, followed by application of solder consisting essentially of zinc or zinc alloy and appropriate fluxes containing metallic salts, at a temperature of about 320.degree. to 500.degree. C. The metallic members may also be joined by addition of nickel or n...
