  • Patent number: 6827220
    Abstract: This invention is directed to the use of non-sulfur containing compounds as collectors in the froth flotation of certain mineral sulfide and metallic compounds. These non-sulfur-containing compounds may be from natural sources, such as vegetable oils, or synthesized commercial sources. These non-sulfide collectors can be used singularly, in combinations, and in mixtures with known commercial sulfur containing collectors. These non-sulfur-containing collectors are compatible with common frothers.

  • Patent number: 6613948
    Abstract: 2,3,4,5-tetrafluorobenzene derivatives can be obtained in a particularly advantageous manner by reacting the corresponding chlorobenzene or (chloro, fluoro)-benzene derivatives with a fluorinating agent in the presence of a solvent and a catalyst at elevated temperature, which comprises carrying out the reaction initially under temperature and pressure conditions such that the respective 2,3,4,5-tetrafluoro-benzene derivative continuously distills off through a column, and subsequently setting temperature and pressure conditions such that residual fractions of the 2,3,4,5-tetrafluorobenzene derivative distill off with the corresponding 2,3,4-trifluoro-5-chloro compound.

  • Patent number: 6548541
    Abstract: The synthesis and the use of a series of carboplatin analogs is disclosed. These carboplatin analogs may be represented by cis-Pt(II)L1L2, wherein each of L1 and L2, independently, is the carboxylate of phosphatidylserine, an &agr;-amino acid, a &bgr;-amino acid, or a derivative thereof, wherein each ligand is bidentate with —NH2 and —COO− as the binding sites. The complexes can be used in the treatment of cancer.

  • Patent number: 6523706
    Abstract: A support for casks includes a base structure containing four feet, four frames, and at least two crosspieces. The frames include two upwardly divergent lower tubes, and two vertical upper tubes. Each of the vertical upper tubes is connected to an end portion of one of the upwardly divergent lower tubes. The feet are adapted to rest on a ground surface or on another of the supports. Each of the frames is joined to one of the feet, and the upper tubes are perpendicular to a plane defined by an upper surface of the feet. A first pair of frames is situated in a first plane and secured to each other by an adjacent pair of vertical tubes. A second pair of frames is situated in a second plane, which is parallel to the first plane. The second pair of frames is connected to the first pair by the crosspieces.
