Abstract: PIPE RESTRAINT DEVICE                 ABSTRACT OF THE DISCLOSURE       A pipe restraint device that will prevent pressure-induced separation of cast iron soil pipes or the like joined by a sealing coupling comprises at least one stiff yet forceably springable rod having lengths thereof curved to substantially the outside curvature of the pipe and form-ing two coils spaced apart for encircling respective pipe surfaces at opposite sides of the sealing coupling, with end portions of the rod or rods arranged in oppositely di-rected first and second pairs defining a contractable re-gion of the coils; and structures including at least one rigid strut bracket formed to bridge the sealing coupling axially are engaged with the pairs of rod end portions for displacing them relative to one another substantially tan gentially under great tension and holding them so displaced in immovably tight engagement upon the pipe surfaces.  The coils can be formed by curved lengths of a single rod, or of two separate rods; or by two or more rods each prebent to a U shape or a closed loop form providing two curved lengths, with a rigid strut plate joining portions of these rods away from the strut bracket.  Portions of the curved lengths away from the strut bracket are restrained axially by one or more tying members that bridge a sealing coupling and have edge channels underlying the rods.  Such tying members   in some forms serve also as the gasket confining shield of a pipe joint sealing coupling.

Abstract: ABSTRACT OF THE DISCLOSURE         Improved noncatalytic nonreactive alumina-silica solid for removing carbonaceous and metallic contaminants including nickel and vanadium from hydrocarbon feedstock by short term, high temperature contact comprises mullite and crystalline silica.  In the decarbonizing and demetallizing process, impurities are deposited on the particles of the solid and the major portion of the feedstock is vaporized. After burning carbonaceous deposit from the particles, the hot particles containing nickel and vanadium are recycled into contact with incoming charges of contaminated feedstock. Periodically metals are removed from coke-depleted particles by extraction with a mineral acid at elevated temperature without dissolving or otherwise destroying the alumina-silica particles.  The particles are then reintroduced into the system.  The particles comprising mullite and crystalline silica are obtained by calcining particles of high purity kaolin or kyanite under controlled conditions to assure substantial conversion of silica content of the clay or kyanite to a mixture of mullite and crystalline silica.  Optionally, small amounts of acid insoluble alumina are also present in the particles.

Abstract: This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the polymerization of olefins. The invention particularly relates to the use of silica gel containing from about 6 to about 20 per cent by weight adsorbed water as the catalyst support material. It has been found that such silica gel may be safely added to a solution, of trialkylaluminum to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the majority of the alumoxane component requirement of the catalyst system. An alkylalumoxane coated silica gel is formed to which a trimethylaluminum treated metallocene may be added and the resulting material dried to free-flowing powder. The dry free flowing powder may then be used as a supported metallocene alumoxane catalyst complex for gas phase or liquid phase polymerization of olefins. The supported catalyst produced by such procedure has an activity at least comparable to a catalyst of similar composition which is produced exclusively with trimethylaluminum as the alumoxane forming aluminum alkyl.
