Abstract: An improved fishing rod holder is disclosed for a hard top or other overhead structure of a boat comprising an assembly of interconnected tubular members movable relative to each other so that the rod holder may be rotated between a stationary upright position wherein a fishing rod is held firmly and a downward position wherein a rod may be easily removed from or inserted into the holder. The tubular members of the holder include a base member adapted to be mounted to the boat structure by a weldment attached thereto, a rod tube pivotally connected to the base member and sized to hold the butt end of a fishing rod, and a latch handle sized to fit around the rod tube and further formed to releasably engage the base member coaxially thereby placing the holder in the stationary upright position.

Abstract: An improved halogenator process and system is provided which significantly and economically decreases the level of impurities in the processing of various refractory metals and their halides and particularly hafnium tetrachloride which is condensed from gases produced by the chlorination of Zircon.

Abstract: The present invention relates to the reduction of zirconium and hafnium tetrachloride by magnesium or sodium metal and, more particularly, to an improved reaction vessel design for the reduction reaction including a novel liquid metal seal.
