Abstract: This invention relates to an endwall for a container having a panel portion surrounded by a substantially vertical wall portion which terminates into a narrow rim. The rim is connected to a sidwall of the container. The wall portion extends outward from the container and is adapted to be reformed inwardly into the container in a controlled manner by an external mechanism to reduce the volume thereof after the container has been filled and sealed. The invention also relates to a method of packaging a product in a container having a body opened at one end and closed at an opposite end by an endwall as described above. The method includes the steps of filling the container with a product and sealing the open end, thermally treating the filled and sealed container, and reforming the endwall inwardly into the container. The sequence of steps can be rearranged.

Abstract: A method of forming either a metal or plastic pilferproof closure is disclosed. The closure has an end wall and an annular sidewall depending therefrom. For a metal closure, an annular ring is rolled in the sidewall so that it protrudes outwardly therefrom. The sidewall is scored adjacent to the annular ring to form a plurality of fracturable bridges which divide the sidewall into upper and lower portions. The annular ring is then compressed so as to form an annular bead which at least partially covers the bridges. The upper portion is susceptible to being deformed about the threaded neck of a container while the lower portion is adapted to be at least partially turned inward and into engagement with an annular shoulder formed on the container below its threaded neck. The annular bead serves to protect the fingers of a person who is removing the closure from coming in contact with the sharp edges of the broken bridges.

Abstract: A mount for connecting a satellite television antenna to a pipe mast. The mount includes a support assembly of a linear upright member and a cross member which are adapted for attachment to a peripheral portion of a parabolic dish antenna and a fitting attached to a lower end of the upright member which connects with a pipe mast so as to enable or prevent rotation of the support assembly with respect to the mast axis and to enable or prevent varying the angle of inclination of the upright member with respect to vertical.

Abstract: A method is disclosed for forming a thermally activated pressure relief valve which is designed to be attached to a pressure vessel. The valve contains a body having an inlet and an outlet in fluid communication with each other and an insert having a helical groove formed about its outer periphery. The method includes securing the insert in the outlet such that the helical groove cooperates with the body to form a helical passageway. A molten fusible material is then introduced into one end of the helical passageway. A force is exerted on the material to cause it to move through the helical passageway and displace any trapped air, gas or foreign matter which might be present therein. Once the material completely fills the passageway, it is allowed to cool and solidify. This method is advantageous in producing a safety relief valve which can operate at higher service pressures and temperatures over an extended period of time.

Abstract: A process and apparatus for removing volatile contaminants from scrap metal is disclosed. The process is carried out in a furnace maintained at a relatively constant temperature and having a first zone in which volatiles contained on the surface of the metal are vaporized and a second zone in which carbon contained on the surface of the metal is pyrolyzed. The furnace also has a conveyor for transporting metal therethrough at a specific speed to ensure complete vaporization and pyrolysis of the contaminants. The process includes the steps of sufficiently vaporizing the volatiles without oxidizing the metal, the vaporizing producing fumes containing unburned hydrocarbons. The hydrocarbon fumes are then burned to produce hot gas which is recirculated to the furnace. The hot gas contacts the incoming metal and vaporizes the volatiles contained thereon.

Abstract: A method of forming an integral rivet in a sheet metal panel by successively coining portions circumscribing a central portion thereof so that the end panel stock is not stretched and a long shanked rivet is produced. The rivet has a relatively thin wall shank and a relatively thick crown which provides sufficient metal for stacking into a rivet head having a wide formable flange.

Abstract: A process and apparatus is disclosed for removing volatile contaminants from scrap metal. The process is carried out in a furnace maintained at a relatively constant temperature having a first zone in which volatiles contained on the surface of the metal are vaporized and a second zone in which carbon contained on the surface of the metal is pyrolyzed. The furnace also has a vibrating conveyor for transporting metal therethrough at a specific speed. The process includes the step of vaporizing and fluidizing the volatiles to produce fumes containing unburned hydrocarbons without oxidizing the metal. The hydrocarbon fumes are then burned to produce hot gas which is recirculated to the furnace so as to contact new incoming scrap metal.

Abstract: A method and apparatus are provided for electrocoating the interior and exterior of a metal container using a dual flow system. The interior and exterior surfaces of the metal container may be coated with the same or different coating weights. An electrically conductive probe, including a nozzle, is inserted into a metal container and an electrically conductive housing is enclosed around the container to seal the container therein. Two separate passageways are provided such that one passageway supplies coating material about the container between the container exterior and the outer housing and a second passageway is formed by the hollow probe and the interior of the container. Electrocoating material is caused to flow into each of the passageways.

The apparatus includes at least one coil spring which is disposed generally horizontally in the container with one end anchored to the container and the other end, which is disposed near the outlet, connected to a lever arm and crank for cyclically extending and contracting the spring. Such cyclic extension and contraction of the spring moves or at least encourages the flow of the particulate material to the outlet for gravity discharge therefrom and essentially eliminates problems of bridging and rat holes in the material.

Abstract: Aluminum chloride is produced from clay containing aluminum oxide and silicon oxide by chlorinating clay in at least two stages with a mixture consisting of a chlorinating agent, a reducing agent, an alkali metal compound catalyst and silicon tetrachloride in which the proportions and amounts of the feed gases to each stage are separately regulated to suit the needs of the aluminum chloride production reaction in that stage. The effluent gases from the successive stages are collected and the silicon tetrachloride is separated from such gases and recycled back into the reactors to promote chlorination of the aluminum oxide in the clay while suppressing net chlorination of the silicon oxide fraction of the clay.
