Abstract: A splicing unit for integrally joining ends of seal strip material to form a continuous annular seal ring comprises two reinforced elastomeric ply strips with an unreinforced elastomeric gum interposed between them to form an H-section configuration, the length of the unit being substantially the width of the seal strip while the thickness of the gum between the ply strips is substantially the thickness of the seal material to be joined. The ends of the seal strip are inserted between the legs of the H-section on either side of the unreinforced gum and cured to form the integrally spliced seal ring.

Abstract: A bottom tension boom for collecting floating material, such as an oil spill upon a body of water, has a barrier containing an upper or freeboard portion, a lower or skirt portion which is submerged in and extends downwardly into said body of water, and pleats or slack portions which extend generally vertically across the barrier. A plurality of flotation elements is attached to the freeboard portion of the barrier and thereby supports the barrier as a whole upon the water. A lattice containing a plurality of strands made from an extensible material is attached to the skirt and extends downwardly therefrom. The lower portion of the lattice is connected to a bottom tension line which is shorter in length than the corresponding portion of the barrier. The boom is towed by tow lines connected solely to the bottom tension line and effects a backward skirt inclination with respect to the position of the bottom tension line.

Abstract: The grapevine particularly characterized by its production of berries which are generally similar to those produced by the Emperor Grapevine (unpatented) but which is characterized as to novelty by producing grapes which are mature for commercial harvesting approximately September 1 through September 15 under the ecological conditions prevailing in the San Joaquin Valley of Central California.
