Abstract: This invention is a process for the alkylation of isoparaffin with olefins using a catalyst system comprising certain transition aluminas promoted with a Lewis acid (preferably BF.sub.3), and free Lewis acid. The product alkylate is a complex mixture of branched paraffins suitable for use as a high octane blending component for motor fuels.

Abstract: This invention provides an improved process for the conversion of reactant into a reaction product, in the presence of a solid acid catalyst comprising sulfonic acid groups covalently bonded to a polymeric chain, wherein the improvement comprises increasing the rate of conversion, on an equivalent sulfonic acid basis, by providing, as said polymeric chain a compound represented by the general formula:M(O.sub.3 ZO.sub.x R).sub.nwherein M is a tetravalent metal ion; Z is a pentavalent atom, selected from the group consisting of elements of Group V of the Periodic Table of the Elements having an atomic weight greater than 30; x varies from 0 to 1; R is select d from the group consisting or organo radicals and mixtures of hydrogen radicals and organo radicals; and n varies from 1 to 2; provided that n is 1 when R is terminated with a tri- or tetraoxy pentavalent atom.

Abstract: The present invention provides a method of making a polymer by reacting, in the absence of water, an organic compound having the general formula R-H wherein R represents an organo radical having at least one unsaturated carbon-carbon bond and H is covalently bonded to one of said carbons, with PX.sub.3, wherein X is a halide radical, and zirconium ions to yield a reaction product and oxidizing and hydrolyzing such reaction product to yield a polymer represented by the general formula Zr(O.sub.3 PR).sub.n wherein n varies from about 1 to about 2.5. R may comprise sulfonic acid groups or may comprise sulfonatable site for sulfonation during the oxidation step. In either case, the resulting product is useful as an acid catalyst.

Abstract: This bolt lock is for a sliding patio door. Primarily, it consists of a housing containing a lock mechanism for the outward and inward travel of a pair of toothed lock bolts, which are slideably received between a pair of side frames of said housing. It also includes a sector gear and a small gear, which serve to advance and retract said pair of toothed lock bolts, simultaneously, when the lock cylinder of the combination is turned by a key.

Abstract: Synergistic herbicidal activity is displayed by compositions comprising the following two components:(a) a pyrrolidone of the formula ##STR1## and (b) an acetanilide of the formula ##STR2## in which R.sup.1 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and chlorine;R.sup.2 is selected from the group consisting of hydrogen, C.sub.2 -C.sub.6 alkoxyalkyl, and C.sub.3 -C.sub.6 carbalkoxyalkyl;R.sup.3 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and chlorine;R.sup.4 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and chlorine; andR.sup.5 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, chlorine, and --NHSO.sub.2 CF.sub.3,at a weight ratio of (a) to (b) of from about 0.1:1 to about 50:1.

Abstract: A culture collection and transport device which is uniquely configured employing a piston-like element which is adapted to maintain a medium-carrying chamber in fluid-tight relationship until such time as a specimen sample is introduced into the device and selectively put in contact with the medium. The culture medium preserves the viability of microorganisms comprising the specimen sample. The piston-like member is pressure responsive so that ambient temperature and pressure changes will not cause leakage of the medium from the medium-carrying chamber and wherein a simple, force oriented movement of a specimen collector on swab, containing a culture, is readily put into contact with the viability-maintaining, transport medium.

Abstract: Synergistic herbicidal activity is displayed by compositions comprising the following two components:(a) an anilide of the formula ##STR1## in which R is a member selected from the group consisting of C.sub.1 -C.sub.10 alkyl, C.sub.2 -C.sub.4 alkenyl, and C.sub.3 -C.sub.5 cycloalkyl; and(b) a thiocarbamate of the formula ##STR2## in which R.sup.1 and R.sup.2 are independently C.sub.1 -C.sub.4 alkyl, or R.sup.1 and R.sup.2 conjointly form C.sub.2 -C.sub.7 alkylene; and R.sup.3 is C.sub.1 -C.sub.4 alkyl, in a weight ratio of anilide to thiocarbamate of 0.001-50:1.
