Abstract: A system and method for promoting artistic creation and compensation therefor includes a first step of accepting payment from an advertiser to have an artist perform a message in the voice of the artist within an entertainment production of the artist; a second step of creating an entertainment production by the artist wherein the message is integrated into the entertainment production; a third step of converting the entertainment production to an electronically readable file; a fourth step of enabling consumer download of the electronically readable file using the Internet; and, a fifth step of paying the artist for a consumer download of the electronically readable file.

Abstract: A process for the oxidation of organosulphur compounds with hydrogen peroxide is provided. The process employs solid supported polyacids comprising tungsten, molybdenum and/or vanadium as catalysts. The supports are selected from compounds, preferably oxides, of Group IIa, IIb, IIIb, IVa and IVb elements, and strong base ion exchange resins. Certain embodiments of the process provide for the oxidation of sulphides to sulphoxides or sulphones, particularly for the oxidation of penicillins to penicillin sulphoxides. Other embodiments of the process provide for the selective oxidation of thiols to sulphoxides.

Abstract: Alkenes can be expoxidized with hydrogen peroxide using a homogeneous heavy metal catalyst, but discharge of spent reaction mixtures releases the heavy metal in the environment. The problem can be ameliorated by selecting a heterogeneous catalyst system comprising a tungsten-containing heteropolyacid supported on selected Group IIa, IIb, IVa or IVb inorganic supports or on a strong basic resin, which catalyst has either been calcined after impregnation of in the impregnation stage an alcoholic solution of the heteropolyacid is employed and by employing a nitrilo or oxygenated polar solvent reaction medium. A number of preferred heteropolyacids satisfy the empirical formula M.sub.3/n PW.sub.w MO.sub.12-w O.sub.40 in which w represents an integer of at least 1, M represents a counterion and n its basicity. Preferred supports include activated alumina, calcined at 400.degree. to 600.degree. C. and cross-linked quaternary ammonium-substituted polystyrene resins.

Abstract: Hydroxylation of phenol is prone to the production of tarry by-products. Selective hydroxylation of phenol can be obtained by reacting a limited amount of hydrogen peroxide with phenol in solution in a compatible organic solvent and in the presence of a catalyst that is at least partly soluble in the reaction medium and is the salt of a heteropolyacid of general formula: i) Q.sub.3 PMo.sub.m W.sub.12-m O.sub.40 or ii) Q.sub.3+v PM.sub.n V.sub.v O.sub.40, in which Q represents a compatible organic cation, m is zero or an integer less than 6, M represents molybdenum or tungsten, v is an integer which is up to 3, and n is an integer such that n+v=12. A preferred organic cation comprises cetyl pyridinium. Selectivity towards catechol is particularly observed employing heteropolyacid salts in which m=0 in formula i) and when n=11 and M=tungsten in formula ii) and towards hydroquinone when n=11 and M=molybdenum in formula ii). Preferably the reaction medium comprises acetonitrile.

Abstract: An endless, belted-chain conveyor as customarily employed in various types of agricultural crop-harvesting equipment is provided with elongate attachment devices for receiving and holding accessories designed to protect a harvested crop or other conveyed material from bruising contact with portions of the conveying surface of the conveyor, such as sprocket runs or with stationary side-walls of the conveyor. The attachment devices comprise elongate portions advantageously in the form of cantilevered tongues directed toward the longitudinal axis of the conveying reach of the conveyor and spaced from the conveying surface thereof sufficiently to receive protective accessories that are either attached to such cantilevered tongues or adapted to be so attached.
