摘要： A self cleaning ball bearing swivel connector. The first swivel member is equipped with a seal engaging surface defined by a frusto-conical shoulder and a cylindrical neck. The end of the tubular body which contains the bearing assembly is adjacent to but spaced a distance from the shoulder and together with the shoulder and the neck defines a seal receiving space. A flanged seal is supported in the seal receiving space and the flange is adapted to serve as a one-way flap type valve, permitting debris inside the seal receiving space to be extruded by centrifugal force as the swivel connector rotates, yet preventing the entry of debris or surrounding liquids. The angled surface provided by the frusto-conical shoulder decreases the resistance to the centrifugal force propelling the debris out of the seal receiving space and, thus, facilitates the extrusion of debris.

摘要： An alkylation process wherein isoparaffin hydrocarbons are alkylated with olefin hydrocarbons in the presence of an alkylation catalyst comprising H.sub.2 SO.sub.4 to yield alkylated hydrocarbons suitable for use in motor fuels. Such process includes an isoparaffin pretreatment step wherein isoparaffin charge is contacted with spent alkylation catalyst to remove contaminants from the isoparaffin which are reactive with sulfuric acid under alkylation conditions.
