  • Patent number: 11432457
    Abstract: A multiple variety planter has a direct vacuum system that allows for planting multiple varieties of seed while reducing occurrences of mis-planting events or planting inconsistencies such as multiples and skips by providing highly controllable seed meter vacuum performance characteristics that are controllable on a row-by-row basis. The direct vacuum system may include a vacuum unit at each row unit of the planter to apply a vacuum pressure to a seed meter at the row unit. Each vacuum unit may be individually and variably controlled to apply different vacuum pressures based on which seed variety is being planted with the respective seed meter at a given time.
    Type: Grant

  • Patent number: 8460937
    Abstract: A method of screening catalysts for liquid-phase selective hydrogenation by preparing a test catalyst by adding a promoter to a reference catalyst; preparing a liquid reactant stream comprising C2H2 dissolved in n-methyl-2-pyrrolidone; testing the test and reference catalysts by contacting the reactant stream and gas mixture comprising hydrogen and carbon monoxide in continuous flow with the test catalyst and reference catalyst, respectively, at selective hydrogenation reaction conditions to produce a product stream, condensing substantially all of the n-methyl-2-pyrrolidone from the product stream; measuring the concentrations of products comprising C2H2, C2H4, and C2H6 in the product stream at steady state; determining performance parameters for the test catalyst and the reference catalyst comprising the respective C2H2 conversion Sc and C2H4 selectivity relative to C2H6 Ss; and comparing the test catalyst performance parameters to those for the reference catalyst.
