  • Granular calcium hypochlorite coated with a low melting inorganic salt by spray graining
    Patent number: 4048351
    Abstract: A process is described in which granular calcium hypochlorite particles are encapsulated with at least one layer of a hydrated low melting inorgnaic salt. In this process granular calcium hypochlorite particles are lifted from a moving bed to the upper part of a distribution zone and the lifted particles are released to fall downwardly through the upper portion to the moving bed. A molten hydrated low melting inorganic salt is sprayed onto the falling particles above the moving bed, and the coated particles are cooled to provide at least one solid outer layer of said low melting hydrated inorganic salt.

  • Quick-connect coupling
    Patent number: 4045055
    Abstract: The invention relates to a quick-connect coupling for use with a conventional threaded male coupling member in which a female coupling member is provided of such design that the male member may be inserted and locked without moving or rotating the female member. A resilient snap ring is situated at one end thereof within a tubular shell member and is provided at said end with internal threads for engaging and holding the male member in position. The snap ring possesses a peripheral bevel on the outer surface of said threaded end which seats within a correspondingly enlarged section of said shell to hold the snap ring in locking engagement with the male member. In the event that force is applied to the coupling to pull it apart, the bevel is forced against an interior wall of said enlarged section and the ring is forced to contract in diameter to effect said locking engagement.

  • Method of removing rods from metallic anodes
    Patent number: 4037304
    Abstract: A method of removing a portion of a rod from a metallic anode of the type used in chlor-alkali electrolytic cells. The anode is of the type having a foraminous surface comprised of a plurality of closely spaced substantially parallel rods with the rods being welded to a supporting structure at at least two locations. The method comprises mounting a drill bit in a drill so that no more than about 0.250 inch of the free end of the drill bit extends unsupported from the chuck. The rotating drill bit is advanced through the wire to be removed at at least two locations, with the rod free of weldings between the two locations. The portion of the rod may then be removed for testing or other purposes.
