    摘要: A method and apparatus are disclosed for determining the concentration of individual components within a fluid mixture by determining the permittivity of the individual components. The method and apparatus use a reference sensor and at least one measurement sensor positioned inside the same sensor device that is immersed in the fluid mixture to be measured. Signals, such as radio frequency or microwave, are sequentially transmitted at multiple, known, constant frequencies to and reflected from both the reference and measurement sensor(s). Permittivities of the individual components are determined from these transmitted and reflected signals and information about the concentration of the individual fluids and other compounds within the fluid mixture and the density of the fluid mixture are produced. Repetitive sampling and processing of these signals allow determination and real-time monitoring of the concentration of individual components within a mixture of fluids. The present invention provides self-calibration, accurate frequency maintenance and self-selection of an operating frequency range.

    摘要: The present invention provides a process for producing a water-miscible metalworking fluid by combining water, and additives chosen from plasticizers, chelating agents, biocides, surfactants, dispersants, dyes, odorants, extreme pressure agents, anti-oxidants and corrosion inhibitors with a polyether polyol produced by mixing an active hydrogen compound with a double metal cyanide (DMC) catalyst in a reactor vessel, charging to the reactor vessel a mixture containing two or more alkylene oxides to activate the catalyst and continuously feeding one or more alkylene oxides to produce the polyether polyol, wherein a 1% solution in water of the polyether polyol has a cloud point of greater than about 32° C., the equivalent weight of the polyether polyol is greater than about 1,000 Da, and a four-hour aerosol inhalation exposure to the polyether polyol has a LC50 of greater than about 0.50 mg/L. The water-miscible metalworking fluid produced by the inventive process may find use in cooling and/or lubricating metal surfaces during one or more of grinding, cutting, boring, drilling and turning of metal parts.

    摘要: The process of the present invention provides for the manufacture of lower molecular weight DMC-catalyzed polyols than is possible using non-acidified continuous addition of starter (CAOS) feeds, by adding excess acid to a starter feed stream over that required for mere neutralization of the basicity of the starter. The benefits of the invention also extend to starters which do not contain basicity. Polyether polyols made by the inventive process may be used to produce improved polyurethane products such as coatings, adhesives, sealants, elastomers, foams and the like.
