Abstract: A sensor can be manufactured by printing a working electrode onto a substrate using aerosol jet printing. Sensing chemistry (e.g., enzyme-based ink that including detection chemistry) also can be printed onto the working electrode using aerosol jet printing. A reference electrode also can be printed on the substrate at a position spaced along the substrate from the working electrode. In certain examples, the substrate can be positioned within a lumen of a skin piercing member of a sensor module.

Abstract: A sensor module is disclosed herein. The sensor module includes a main housing defining an analysis zone within the housing. The sensor module also includes a skin piercing member mounted within the main housing. The skin piercing member is movable relative to the main housing between a retracted position and an extended position. The main housing of the sensor module defines a fluid sample flow passage that extends from a sampling end of the main housing to the analysis zone. The fluid sample flow passage includes a funnel structure through which the skin piecing member extends when in the extended position. The fluid sample flow passage also includes capillary flow enhancing slots that extend outwardly from opposite sides of the funnel structure.

Abstract: An engagement mechanism amplifies an applied force to a lever by torque conversion about a rotation point to a higher reaction force that is applied to a master cylinder assembly for operation of a hydraulic clutch or brake system.

Abstract: A process for the production of alkylbenzene includes the steps of introducing benzene and an olefin feed into a first alkylation reaction zone in the presence of a first alkylation catalyst under first alkylation reaction conditions to produce alkylbenzene and a vapor containing unconverted olefin; absorbing the unconverted olefin into an aromatic stream containing benzene and alkylbenzene; and, introducing the aromatic stream containing absorbed olefin into a second alkylation reaction zone containing a second alkylation catalyst under second alkylation reaction conditions to convert the absorbed olefin and at least some of the benzene of the aromatic stream to alkylbenzene. The process is particularly advantageous for the alkylation of benzene with ethylene to produce ethylbenzene. About 99.9% conversion of ethylene is achieved overall, with a substantial reduction in the required catalyst.

Abstract: A process for the production of alkylbenzene includes introducing benzene and an olefin feed into a first alkylation reaction zone in the presence of a first alkylation catalyst under first alkylation reaction conditions to produce a first alkylation effluent containing alkylbenzene and a first alkylation overhead stream. The first alkylation overhead stream is separated into a liquid portion containing benzene and a vapor portion containing unconverted olefin and ethane. A major portion of the unconverted olefin in the vapor portion of the first alkylation overhead stream is absorbed into a de-ethanized aromatic lean oil stream containing benzene and alkylbenzene in an absorption zone to produce a rich oil stream containing olefins and at least some of the ethane.

Abstract: A process for producing an alkylaromatic compound includes contacting a dilute olefin feed with a lean oil stream containing aromatic compound and alkylaromatic compound in an absorption zone to provide an alkylation reaction stream containing aromatic compound, alkylaromatic compound and olefin. The alkylation reaction stream is reacted under alkylation reaction conditions in an alkylation reaction zone to provide an effluent containing the aromatic compound and alkylaromatic compound. The effluent of step is separated into the lean oil stream which is recycled to the absorption zone and a product portion from which an alkylaromatic product is recovered.
