A container includes an oil spout mounted to a neck of the container, with the spout including an accordion pleated spout hanging conduit permitting telescoping projection of the spout relative to the neck, with a cap seal mounted at an entrance of the neck, with the cap seal having a cap seal first end fixedly mounted to the spout exit opening, with a cap seal second end having a pull tab for initial pulling and separation of the cap seal relative to the spout exit opening.

An apparatus for the manufacture of selectively apertured thermoplastic sheet or film, comprising a rotatable molding element means for receiving the film and which means has a predetermined pattern therein wherein as the film is contacted with the rotatable molding element means and a fluid pressure differential is applied to the surface of the film, a desired pattern of perforated areas and non-perforated areas are imparted to the film with each of said areas being continuous across the web of the film and alternating in the machine direction.

There is disclosed a non-return indicator for a turn signal in a road vehicle which may be installed with at most three or four electrical connections; it includes a housing with four lead wires extending to a vehicle ground, a plus 12 volt wire, a right turn circuit wire tap, and a left turn circuit wire tap. The indicator includes a binary counter IC for registering a count of 64, 128, or 256; the count setting may be selectable; a separate time delay IC to reset the counter may be provided. A pair of back to back diodes in the right turn and left turn-connected conductors keep them isolated while the counter receives a count for either right turn or left turn signal flashes; upon reaching the predetermined count the counter signals a gate circuit to provide either a steady or intermittent current to an indicator buzzer, beeper or lamp. Alternatively a storage capacitor will permit the counter or other IC's to be powered only from the turn circuits.

The invention is a multiorifice structure and method of manufacture. The structure comprises a plurality of triangularly shaped orifices angularly disposed with respect to a common axis. The structure is formed by fusing together concentric alternating layers of cylindrical members and parallel rods angularly disposed with respect to the axis of the cylindrical members. The fused structure is sliced generally normal to its axis to produce a plurality of multiorifice wafers or discs. The interstices between the rods and the cylindrical members form a plurality of small triangularly shaped orifices particularly well suited to use as an atomizer for an internal combustion engine fuel injector valve.

A process for removing dissolved halogen gas and oxyhalide ions from an aqueous alkali metal halide solution containing them which comprises reacting said aqueous alkali metal halide solution with an inorganic peroxide, and adjusting the pH of said aqueous alkali metal halide solution to a pH within the range from about 6 to about 11 with an inorganic base, whereby a purified alkali metal halide solution of reduced concentration of said dissolved halogen gas and oxyhalide ions is produced.

Current efficiency in an electrolytic membrane cell for the production of concentrated potassium hydroxide is considerably increased by employing in the electrolytic membrane cell a membrane selected from a group consisting of an amine modified perfluorosulfonic acid membrane such as a primary amine, diamine, or polyamine modified perfluorosulfonic acid membrane, and a laminated perfluorosulfonic acid acid membrane, and a laminated perfluorosulfonic acid membrane comprised of at least two unmodified perfluorosulfonic acid membranes of different thickness and different equivalent weight.

A rotatable perforated molding element for embossing and/or perforating thermoplastic sheet or film, the molding element including a series of perforated strips having two parallel sides and two parallel ends, the strips being wrapped about a supporting drum in a manner such that the ends of the molding strips lie in a plane generally perpendicular to the axis of rotation of the molding element and the sides of the adjacent strips contact each other, and a method for connecting the rotatable perforated molding element to a supporting drum including wrapping a series of perforated strips having two parallel sides and two parallel ends about the supporting drum in a manner such that the ends of the molding element lie in a plane generally perpendicular to the axis of rotation of the molding element and the sides of the adjacent strips contact each other, and securing the ends of the strips to the drum.

A process for the manufacture of thermoplastic sheet having elliptical perforations including a rotatable molding element having a series of hexagonal-shaped depressions having centered therein elliptical holes, the elliptical holes having a major axis and a minor axis, the major axis being oriented parallel to the direction in which the molding element is rotated, a means for applying a fluid pressure differential to a surface of the thermoplastic sheet to force the sheet against the molding element to effect rupturing of the sheet and the formation of elliptical holes in the sheet.

A perforated thermoplastic film with tapered capillaries which has an increased liquid flow rate through the tapered capillaries and a method for making such a film. The method includes subjecting a perforated thermoplastic film having tapered capillaries to a corona discharge treatment sufficient to increase the flow rate of liquid through said perforated film.；The film made in accordance with the invention has a much higher liquid

A process and apparatus for the manufacture of thermoplastic sheet having elliptical perforations, the process including placing a thermoplastic sheet into contact with a continuously rotating molding element having a series of elliptical holes therein in which the major axis of the elliptical holes is oriented parallel to the direction in which the molding element is rotating, subjecting a surface of the thermoplastic sheet to the action of a fluid pressure differential to cause the material to flow into the elliptical holes of the molding element while maintaining the pressure differential to effect rupturing of the thermoplastic sheet and the formation of elliptical holes in the sheet, and continuously removing the molded portions of the thermoplastic sheet from the molding element. The apparatus for the manufacture of perforated thermoplastic sheet products having elliptical holes therein includes a rotating molding element having a series of elliptical holes therein in which the major axis of the ellipse is oriented parallel to the direction in which the molding element is rotating.
