  • Patent number: 5643494
    Abstract: A process for the preparation of aromatic hydroxy carboxylic acids by reacting alkali metal phenolates or alkali metal naphtholates with alkali metal carbonates and carbon monoxide, with subsequent acidification, wherein the solid starting materials--alkali metal carbonate and/or alkali metal phenolate or naphtholate--are metered into the reaction mixture in the form of one or more dispersions in an inert organic liquid.The process according to the invention enables the preparation of aromatic hydroxy carboxylic acids in good yields and with high chemical selectivity. Additional measures for increasing the selectivity, as described for example for the Kolbe-Schmitt reaction in EP-A 0 053 824, EP-A 0 081 753 and EP-A 0 254 596, and for the reaction with CO and carbonate in, for example, WO 91/11422, are unnecessary.

  • Patent number: 5644069
    Abstract: A method for identifying a single fuel vapor in an atmosphere of interest that is selected from the group consisting of at least two fuels and that is the sole fuel component of the atmosphere, comprising the steps of: providing a plurality of measuring means that are at least equal in number to the types of fuels that compose the fuel group and which have different sensitivities to the respective fuel vapors; presetting the relationship between the magnitudes of the outputs from the respective measuring means at various fuel vapor concentrations in such a manner that it differs from one fuel vapor to another; placing said measuring means in the atmosphere of interest containing said single fuel vapor as the sole fuel component; measuring the concentration of that fuel vapor; determining the relationship between the magnitudes of outputs as obtained from the respective measuring means; and comparing the thus determined relationship with the preset relationships, thereby identifying the fuel vapor in the atmos

  • Patent number: 5643502
    Abstract: A polymeric composition having improved toughness and conductivity comprising carbon fibrils, at least a portion of which are in the form of aggregates, wherein, as measured on an area basis, substantially all of the aggregates are less than about 35 .mu.m in diameter. A polymeric composition having improved toughness and conductivity is prepared by combining carbon fibrils, at least a portion of which are in the form of aggregates, with a polymeric material, mixing the combination to distribute the fibrils in the polymeric material and applying shear to the combination to break down the aggregates until substantially all of the aggregates are less than about 35 .mu.m in diameter.

  • Patent number: 5641467
    Abstract: The invention relates to a method and apparatus for safely producing hydrogen peroxide by injecting dispersed minute bubbles of hydrogen and oxygen into a rapidly flowing liquid medium. The minute bubbles are surrounded by the liquid medium of sufficient volume for preventing an explosive reaction between the hydrogen and oxygen. The liquid medium is formed of an acidic aqueous solution and a Group VIII metal catalyst. Hydrogen is sparged into the flowing medium for dissolution of the hydrogen in the medium. Oxygen bubbles are reacted with the dissolved hydrogen for producing hydrogen peroxide. Preferably, the liquid medium has a velocity of at least 10 feet per second for providing a bubbly flow regime in the reactor. The invention allows the direct combination of oxygen and hydrogen while preventing propagation of an explosive condition within the reactor. The method and apparatus provide for the safe production of hydrogen peroxide with low manufacturing costs.

  • Patent number: 5641096
    Abstract: The dispenser has a plunger which is pressed downwardly by the user to dispense condiments, such as salt, pepper, sugar, spices, etc. The plunger structure has a dispensing head which passes through an outlet opening in the base of the device. The outlet opening through which the dispensing head passes is sealed by use of a seal structure forming a flexible flap contacting the head. The seal is secured in a base which can be removed to provide a wide opening for refilling the container. The device dispenses a predetermined quantity of condiment with each stroke reliably and with a minimum danger of jamming.

  • Patent number: 5640234
    Abstract: Disclosed and claimed is an optical sensor for the detection of chemical species. The optical sensor includes an optical waveguide having a guiding thin film. The thickness of the refrative index of the guiding thin film changes due to adsorption or absorption of the chemical species or reaction of the chemical species with the guiding thin film. The thickness of the guiding thin film is above the cutoff thickness in the presence of gaseous or liquid chemical species to be detected. And, the thickness of the guiding thin film is below the cutoff thickness in the absence of such chemical species.
