  • Patent number: 6032486
    Abstract: A novel pierced-ear earring comprises a toggle having inner and outer sides and an earpost attached to the inner side. A perforation passes through two other sides of the toggle, and an upper portion of a loop is positioned within the perforation. A pendant having first and second faces comprising non-identical ornaments is attached to a lower portion of the loop. The loop and pendant are rotatable through 180 degrees about the axis of the perforation and, together with the toggle and earpost, are rotatable through 180 degrees about the axis of the earpost. A novel method of reversing the novel earring comprises rotating the entire earring about the axis of the earpost and simultaneously rotating the loop and pendant about the axis of the toggle perforation. The earpost, toggle and loop comprise a novel finding or component for use in manufacture of jewelry.

  • Patent number: 5439859
    Abstract: Alkanes are dehydrogenated by passage through alternating dehydrogenation zones and selective oxidation zone(s), in which latter zone(s) hydrogen produced in the preceding endothermic dehydrogenation reaction is selectively oxidized to generate heat for the succeeding dehydrogenation reaction. New catalyst compositions are prepared comprising reduced and sulfided nickel crystallites on siliceous supports which have been treated with chromium compounds and oxidized to provide surface-anchored chromyl species. Also new catalyst compositions are prepared by sulfiding nickel-containing compositions with carbonaceous sulfur compounds such as dialkylsulfoxides. Another embodiment of the invention is catalyst and dehydrogenation therewith, in which pores having radius of 50 to 200 Angstroms occupy pore volume from 0.30 to 1.50 ml per gram of the support, and pores having radius of 20 to 50 Angstroms occupy pore volume less than 0.1 ml per gram of the support.

  • Patent number: 5132472
    Abstract: Process is provided for oxidation of organic compounds in which a reaction zone is provided, containing an open space and a bed of solid granular catalyst, an organic feedstock and oxygen are passed in gas phase through the open space and then into contact with the catalyst bed, and reaction products are removed from the open space after relatively less contact with the catalyst, and from at least one other location after relatively greater contact with the catalyst. Greater yield of desired product may be obtained in such operation than in operation where all of the reaction products are removed after the greater contact with the catalyst.
