Abstract:
A toy is composed of a projectile and a tube for launching the projectile into the air. The projectile has a pair of wings symmetrically disposed about a longitudinal axis. The leading edge of the wings normally extend outwardly at an oblique angle from a nose which defines the forward end of the projectile. In that position, the projectile will fly through the air. The wings are spring-biased into position for flying. When a manual force opposed to such biasing is applied to the wings, the wings fold inwardly such that the leading edges pivot toward each other. When the wings are closed, the projectile is in a pre-launching position. The projectile is launched into the air via a tube which is hollow and open at one end through which the projectile exits from the tube.
Abstract:
A method and apparatus for stripping electro-deposited metal sheets from a cathode blank. The blank has opposite faces, upstream and downstream ends. At least one sheet is provided on at least one blank face to define upstream and downstream edges. The apparatus comprises a stripping assembly for stripping the electro-deposited metal sheets from the cathode blank, a discharge assembly and a metal sheet out-feed assembly. The discharge assembly is positioned downstream of the stripping assembly and includes opposite guide rollers adapted to engage the metal sheet exiting the stripping assembly. The metal sheet out-feed assembly is positioned downstream the discharge assembly for receiving the metal sheet. When the metal sheet has been stripped from the cathode blank, the guide rollers controllably feed the metal sheet to the out-feed assembly. The method comprises stripping the metal sheets from the cathode and controllably discharging the stripped sheets to an out-feed assembly.
Abstract:
A cathode for use in the refining or winning of metals, typically used in the electro-refining or winning of copper, comprising a substantially flat deposition plate fixedly attached along an upper edge thereof to an elongate hanger bar thereby defining a connection. A protective cladding is attached to the deposition plate and at least partially surrounding the hanger bar such that a cavity is defined in the region of the connection. A corrosion resistant material fills the cavity. In this manner the corrosion resistant material prevents corrosive substances from penetrating the connection. The corrosion resistant material prevents corrosive electrolytic solution and other liquids from corroding the conductive connection between the deposition plate and the hanger bar which would otherwise reduce efficiency of the cathode.
Abstract:
The present invention provides a linear conveyer assembly for cathode plates comprising a continuous timing belt provided with cathode plate conveying assemblies attached thereto and having cam rollers running in a pair of channels running along either side of and parallel to a forward path of the belt. The conveying assemblies insure that the cathode plate conveying assemblies are aligned in an overhead position in such a way that the cathode plates move in a direction substantially perpendicular to a surface thereof. The timing belt is fabricated from a corrosive resistant material and allows an accurate positioning of the cathode plates due to a non-permanent stretch character thereof.

Abstract:
A clinching tool for mechanically interconnecting at least two stacked sheets manufactured of a ductile material comprises a punch and a die axially aligned thereto. The die cavity features a radiused surface profile at its closed end thus facilitating material flow therein during clinching action. This design, while minimizing tooling material stresses and reducing the likelihood of premature tooling failure, allows for clinch fastening of thicker sheets by forming a secure and distinguishable clinch.
