    摘要： A bowling lane maintenance machine has its operating functions designed and controlled in such a manner that the machine may be battery-operated without loss of performance. Included in the operation are special movements of the machine at the pin deck to flick moisture off blades of the squeegee assembly and limited activation of the vacuum motor to reduce battery drain.

    摘要： Hydrothermal synthesis of the natural, alkaline earth zeolites via the alteration of Y-zeolite is presented. Synthetic versions of the zeolites harmotome, heulandite, brewsterite and gmelinite are synthesized from Y-zeolite using alkaline earth cations containing solutions. The effect of the composition of the starting zeolite, the composition of the solution phase, the presence or absence of seeds and the experimental conditions are discussed.

    摘要： A rollable sports ballast base for supporting a sports apparatus support member comprising a base member having a top and bottom surface. The bottom surface contacts a support surface such as a driveway or other playing surface. There is at least one wheel assembly, retractable from a lowered position to a raised position. The wheel assembly includes a pivoting connector coupled to the base member and a wheel bracket coupled to the pivoting connector. The wheel bracket includes an axle, at least one wheel, and a handle extending outwardly from the wheel bracket. The handle is used to pivotally rotate the wheel assembly about a transverse axis. When the handle is rotated away from the base member, the wheel assembly is placed in a lowered position whereby the wheel contacts support surface thus separating the bottom surface of the base member from the support surface.

    摘要： A portable basketball goal support system having a base, a ballast tank, and an arm for supporting a basketball goal support pole can be assembled in a compact configuration for shipping or storage and an expanded configuration for use. The support pole is mounted at a rear portion of the base and angled forward in the expanded configuration. In the expanded configuration, the ballast tank extends at least partially behind the support pole, while in the compact configuration, the ballast tank may be nested within portion of the base, thereby occupying less space. The support pole may be formed with a generally "pear"-shaped cross section defined by large and small curved portions connected by relatively straight sections, such that the large curved portion readily adapts to existing mounting hardware. One or more of the base, ballast tank, and support arm may be formed from plastic with a printed graphics sheet integrally molded therewith.

    摘要： The present invention relates to water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl and its use as organometallic catalysts for asymmetric synthesis of optically active compounds. Asymmetric reactions of the present invention include those reactions in which organometallic catalysts are commonly used. Such reactions include, but are not limited to, reduction and isomerization reactions on unsaturated substrates and carbon--carbon bond forming reactions. Examples of such reactions include, but are not limited to, hydrogenation, hydroboration, hydrosilylation, hydride reduction, hydroformylation, alkylation, allylic alkylation, arylation, alkenylation, epoxidation, hydrocyanation, disilylation, cyclization and isomerization reactions. The catalysts of the present invention provide the advantage of functioning in the presence of water without loss in enantioselectivity relative to the nonsulfonated BINAP catalyst in an organic solvent. As a result, the catalysts of the present invention may be employed in water, water miscible solvents, in aqueous--organic two phase solvent systems and in supported aqueous phase catalysts in organic solvents without loss in enantioselectivity. Further, the catalysts of the present invention may also be effectively employed in highly polar solvents such as primary alcohols and ethylene glycol. The present invention also relates to a method for conducting asymmetric reactions on prochiral unsaturated bonds contained within a compound using the water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl organometallic catalysts of the present invention.
