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.

Abstract: A vehicle includes a fuel cell that generates electricity, a pre-heater electrically coupled to the fuel cell, wherein the pre-heater provides an output, and a component configured to receive a portion of the output, wherein a temperature of the component is changed through receipt of the portion of the output. In addition, a method is described for operating a fuel cell in a vehicle that includes: generating electricity from the fuel cell, and providing a portion of the electricity to a pre-heater, which provides an output to a vehicular component, thereby pre-heating the component.
Abstract: The invention provides a method of making a chewing gum composition containing a water soluble bulk portion, a water insoluble chewing gum base portion, a flavoring agent, and bismuth-containing compounds. The invention provides a method of making a bismuth-containing gum which when chewed multiple times per day, over the period of two weeks, is effective in reducing peptic ulcers by eradicating H. pylori. The chewing gum is also effective in eliminating forms of halitosis. The chewing gum does not have undesirable side effects, such as unpleasant taste and poor chewing characteristics.
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.

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.
Abstract: A support for casks includes a base structure having (a) stanchions which can be disassembled or folded down, (b) complementary intermediate stanchions which can be disassembled or folded down, and (c) pivots or housings for forming mortised connections to the free ends of the stanchions or intermediate stanchions of subjacent supports. The pivots or housings are out of alignment with respect to the stanchions and intermediate stanchions, such that the supports and casks supported thereon are arranged in staggered, parallel rows when stacked. The support can also include a plurality of freely rotating wheels such that the casks seated thereon can be rotated on their axes.

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.
Abstract: A fastener assembly includes (a) a fastening member that includes an out-of-round portion centered about a longitudinal axis and configured for engagement with a torque-transmitting tool, a frustoconical load-bearing surface that extends radially outwardly from the longitudinal axis, and a threaded portion that is centered about the longitudinal axis; (b) a metallic, frustoconical thrust washer having a concave surface positioned adjacent to the load-bearing surface of the fastening member, and a convex surface; and (c) a pressure ring that includes a flange, a frustoconical load-bearing surface formed by the flange and positioned adjacent to the convex surface of the thrust washer, and a frustoconical undersurface oriented to contact a complementary depression in a workpiece.
