  • Patent number: 5580497
    Abstract: Preparation, structure, and properties of mixed metal oxide compositions containing at least strontium, cobalt, iron and oxygen are described. The crystalline mixed metal oxide compositions of this invention have, for example, structure represented bySr.sub..alpha. (Fe.sub.1-x Co.sub.x).sub..alpha.+.beta. O.sub..delta.where x is a number in a range from 0.01 to about 1, .alpha. is a number in a range from about 1 to about 4, .beta. is a number in a range upward from 0 to about 20, and .delta. is a number which renders the compound charge neutral, and wherein the composition has a non-perovskite structure. Use of the mixed metal oxides in dense ceramic membranes which exhibit oxygen ionic conductivity and selective oxygen separation, are described as well as their use in separation of oxygen from an oxygen-containing gaseous mixture.

  • Patent number: 5289856
    Abstract: A special nozzle is provided to recover hydrocarbon vapors emitted during fueling and remove condensate collected in the vapor line, as well as to dispense fuel and removed condensate to customer tanks. In the preferred embodiment, the special nozzle has a venturi sleeve with a valve seat positioned adjacent venturi ports. One of the venturi ports communicates with a condensate liquid pickup tube which removes condensed gasoline vapors in the vapor return hose. Another of the venturi ports communicates with a liquid sensing tube and an automatic shutoff valve assembly which collectively shut off the flow of gasoline when the customer's tank is filled.

  • Patent number: 5273087
    Abstract: A user friendly vapor recovery nozzle with special signaling devices to signal and assure the customer of proper delivery of fuel and return flow of hydrocarbon vapors. In the preferred embodiment, the signaling devices include both a fuel flow indicator and a vapor flow indicator. The flow indicators can comprise one or more fuel and vapor driven balls, paddle wheels, propellers, spinners, blades, or vanes. In the preferred form, the vapor recovery nozzle has an inner fuel spout to discharge gasoline into a customer's tank and has an outer spout which cooperates with the inner spout to provide a vapor return passageway to return vapors emitted during fueling to a vapor return hose. The nozzle has a liquid sensing tube in the vapor return passageway to sense when the customer's tank is filled. An automatic shutoff valve cooperates with the liquid sensing tube to shutoff the supply of gasoline when the customer's tank is filled.

  • Patent number: 5244017
    Abstract: A vapor recovery process signals to customers the presence of flow of gasoline or other liquid fuel and the return flow of vapors. In the preferred process, a customer's tank is fueled with a vapor recovery nozzle. Vapors emitted during fueling are collected by the nozzle and passed to a vapor return hose and then into a storage tank. A vapor flow indicator on the nozzle signals flow of vapors passing through the nozzle. A separate fuel flow indicator in the nozzle signals fueling, i.e., passing a fuel through the nozzle into the customer's tank.

  • Patent number: 5241114
    Abstract: A method and a system for extending useful life of a basic catalyst are disclosed. The basic catalyst comprises a particulate, porous, siliceous catalyst support and an alkali metal in the +1 oxidation state on the catalyst support surface. The catalyst is suitable for the synthesis of an alpha, beta-ethylenically unsaturated carboxylic acid by condensation of a saturated carboxylic acid with formaldehyde. The method of the present invention contemplates providing a reactor, or a series of reactors, containing the basic catalyst and a confined source of the alkali metal associated with a suitable carrier, upstream of the reactor or reactors. A feed stream to the reactor is passed first through the confined source and thereafter through the reactor while reaction conditions for the condensation reaction are maintained within the reactor. The temperature of the feed stream passing through the confined source can be modulated to control release of the alkali metal from the carrier.

  • Patent number: 5234036
    Abstract: A process comprising fueling a tank, collecting emitted vapors, and recovering condensed vapors. In the process, gasoline is discharged into a fill opening or filler pipe of a tank through a fuel outlet conduit of a nozzle. Gasoline vapors emitted during fueling are collected with a vapor return conduit of the nozzle and conveyed through a vapor return hose. A portion of the gasoline vapors in the vapor hose are condensed and removed from the vapor hose with a condensate pickup tube extending from the nozzle.
