Abstract: A cue tip tool is a cylindrical jig having a longitudinal bore forming its body into a tube that accepts a cue being tipped. The jig body has three equally positioned slots cut through the tubular wall, and the outer surface of the jig has a collar that squeezes the jig against the cue ensuring that the axis of the cue is aligned with the jig. The end of the jig is a cylindrical surface stepped to a larger diameter, and the stepped cylinder is coaxial with the axis of the jig and the axis of the cue. Three auxiliary units configured to separately engage the jig provide for burnishing the end of the cue's ferrule, positioning the cue tip being installed during gluing, and cleaning the cue tip of accumulated chalk debris, while maintaining accurate alignment of the cue tip with the cue's axis.

Abstract: A method and system are provided for hierarchical data warehousing in a context-variable data framework. The method includes building a context-variable data framework. The context-variable data framework comprises 1) a data point of interest 2) one or more contextual hierarchies based on a type for the data point of interest, and 3) an organizational hierarchy. The method further includes populating the context-variable data framework with information relating to the data point of interest. The method also includes storing the context-variable data framework and the information in a centrally accessible data store.

Abstract: A process for performing a catalytic Diels-Alder reaction by reacting a diene with a dienophile in the presence of a heterogeneous catalyst comprising a zeolitic material exchanged or impregnated with ions of a Lewis acidic metal is described. The catalyst, for example, copper-exchanged zeolite Y, may be treated with chiral bis(imine) compounds to direct the chirality of the reaction products. The catalyst can be separated from the reaction mixture and re-used in further Diels Alder reactions.

Abstract: A zeolite-immobilized Lewis acid e.g. copper catalyst for performing carbonyl-ene and iminoene reactions is described. The catalyst can readily be separated from the reaction mixture and re-used in further reactions with minimal reduction in activity.

Abstract: The present invention is directed to a corner trim assembly for walls including first and second polymer pieces which are welded together to form an angled joint for slidably receiving trim pieces at the corners of walls without the use of nails, adhesives or other fasteners.

Abstract: A process for the scrubbing of chlorine is scrubbed from a chlorine-containing gas using an aqueous feed liquor containing an excess of alkali to give an effluent liquor containing chloride and hypochlorite ions is disclosed. The effluent liquor is recycled as part or all of the aqueous feed liquor. For at least part of the time, at least part of the effluent liquor is passed through a fixed bed of a catalyst for the decomposition of hypochlorite ions whereby hypochlorite ions are decomposed to oxygen gas and chloride ions. The resultant catalyst-treated liquor is mixed with the remainder, if any, of the effluent liquor and recycled, optionally together with added fresh alkali solution, as the aqueous feed liquor. Part of the effluent liquor is optionally discharged as a purge stream before or after passage through catalyst bed.

Abstract: Shaped units suitable for use as a catalyst, e.g. for the decomposition of hypochlorite, comprise a compacted particulate mixture of at least one oxide of a Group VIII metal M selected from nickel and cobalt, a calcium aluminate cement, and alumina and/or magnesia, the shaped units having (after ignition in air at 900° C.) a content of a Group VIII metal oxide of 10 to 50% by weight (expressed as the divalent oxide, MO), a calcium oxide content of 1 to 10% by weight, an alumina content by weight that is at least four times the weight of calcium oxide, a total content of alumina plus magnesia of at least 40% by weight, a silica content of less than 1% by weight, and the shaped units having a pore volume in the range 0.2 to 0.

Abstract: Synthesis of small quantities of compounds such as methanol from reagents, especially radio-labelled reagents such as .sup.11 C oxides, in a carrier gas by a catalytic reaction using a catalyst that has been pre-conditioned for the reaction by previous use for the desired reaction and has then been passivated, or has been maintained in the pre-conditioned state, until contacted with said carrier gas. Where the product is adsorbed by the catalyst, it may be desorbed by heating or displaced by contacting the catalyst with a material, e.g. a catalyst poison that is more strongly adsorbed. Such a more strongly adsorbed material may react with the adsorbed catalytic product to produce a desired product.

Abstract: A process of continuous decomposition of oxidizable materials in aqueous media, e.g. pollutants in effluents, by catalytic reaction with an oxidant, e.g. hypochlorite or hydrogen peroxide, in aqueous solution using a fixed bed of a particulate catalyst of at least 1% of nickel or copper oxide, optionally plus a basic oxide, e.g. zinc oxide, on a porous support is disclosed.

Abstract: A billiard cue having a separate handle and shaft utilizes a quick operating connector to join the handle and shaft. The connector consists of male and female sections which are secured in the ends of the handle and shaft. The male section contains a cylindrical bar having an accurately machined diameter which snugly fits into a cylindrical cavity of the female section which is slightly oversized with respect to the male bar's diameter. The male bar and female cavity are axially aligned in the cue sections, and the bar engages the cavity over a linear distance sufficient to ensure accurate alignment of the handle and shaft when joined. Two flats at the end of the male bar provide a reduced diameter portion of the bar tip which fits between partial bulkheads within the female cavity, allowing insertion of the bar into the cavity.
