摘要： The present invention relates to the discovery of compositions which include fluoroethane, 2-fluoropropane or tert-butylfluoride. These compositions are useful as pure components or with at least one of tetrafluoroethane, difluoroethane, hexafluoropropane, a hydrocarbon or dimethylether. These compositions are useful as aerosol propellants, refrigerants, cleaning agent, expansion agents for polyolefins and polyurethanes, refrigerants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents.

摘要： The invention provides for sprayable powder comprising friable granules of agglomerated primary particles of non-fibrillatable fluoropolymer and, optionally, at least one other component, the powder having a bulk density of at least 20g/100cc and average particle size of 5 to 100 micrometers. The sprayable powder is preferably free of water immiscible liquid, and more preferably free of halocarbon liquid. Included among the other components are inorganic fillers, pigments, high temperature resistant polymer binders. In an other embodiment, the invention provides for a sprayable powder comprising friable granules of agglomerated primary particles of a first non-fibrillatable fluoropolymer and at least one other non-fibrillatable component. The invention further provides for a process for preparing the sprayable powder by spray drying a liquid dispersion. In a preferred embodiment, the process includes densifying the granules of agglomerated primary particles that result from spray drying. Densifying may be carried out by mechanical compaction or by contacting the granules with a heated gas to form a fluidized bed. Optional steps of communication and heat treatment may be employed to achieve a desired bulk density and particle size for specific applications.

摘要： A process is disclosed for converting a spent catalyst from conventional fluorination processes into a commercially useful tantalum or niobium salt such as K2TaF7 or K2NbF7. The process broadly relates to dissolving the spent catalyst in water or an aqueous hydrofluoric acid solution, separating and disposing the undissolved residue, extracting the aqueous solution with a suitable solvent such as methyl isobutyl ketone (MIBK), and obtaining useful tantalum products from the MIBK solution such as a tantalum salt.

摘要： A process for using explosion bonding to produce a metal composite. The explosion bonding produces a substantially diffusionless metallurgical bond between the layers. In one aspect, the ductility of at least one of the layers being bonded is increased by heating prior to bonding. In another aspect, a layer comprises explosion bonding a plurality of cladding layer to a backer plate such that the seam between the strips is sealed.

摘要： Procédé d'utilisation du placage par explosion pour produire un composite métallique. Le placage par explosion produit une liaison métallurgique pratiquement exempte de diffusion entre les couches. Dans un mode de réalisation, on augmente la ductilité d'au moins une des couches plaquées en chauffant ladite couche avant le placage. Dans un autre mode de réalisation, une couche est constituée par placage par explosion d'une pluralité de couches de placage sur une plaque de support de telle manière que la ligne de jonction entre les bandes soit refermée.

摘要： The present invention provides a membrane electrode assembly for an organic/air fuel cell comprising a proton exchange membrane, an anode electrode, and a cathode electrode. The proton exchange membrane is made of a highly fluorinated ion-exchange polymer, and it has opposite first and second sides. The anode electrode is comprised of an anode electrocatalyst and a highly fluorinated ion-exchange polymer binder, and the anode electrocatalyst is comprised of platinum and ruthenium supported on particulate carbon. The cathode electrode is comprised of a cathode electrocatalyst and a highly fluorinated ion-exchange polymer binder, and the cathode electrocatalyst is comprised of platinum and cobalt supported on particulate carbon. The invention is also directed to a process for operating such a membrane electrode assembly in an organic/air fuel cell.

摘要： The present invention relates to a process for extruding molybdenum-rhenium alloys into tubes or pipes. The invention is capable of high temperature extrusion of MoRe alloys, which comprise about 10 to 50 w.% rhenium, into a seamless pipe or tube. The steps of the process generally comprise fabricating a MoRe billet or blank which includes a pilot hole that extends along the longitudinal axis of the billet (33), heating the billet to a temperature of at least about 1300 °C, and extruding the heated billet by operation of an extrusion press.
