    Abstract: A driving apparatus is used for simultaneously tensioning the jackbolts of a multi-jackbolt tensioner and includes a central drive gear mounted for rotation along a central drive gear axis. An annular array of spindles surrounds the central drive gear, each spindle independently mounted for rotation, with one spindle associated with one of the jackbolts. A socket on one spindle end is configured to receive one of the jackbolts. A spindle gear surrounds each spindle and is configured to rotate the spindle. The spindle gear is meshed with the central drive gear to be rotated by the central drive gear, wherein at least one spindle gear is offset along the central drive gear axis from at least another spindle gear. A slip clutch is positioned radially between each spindle gear and the associated spindle, wherein rotation of the jackbolts is up to a torque setting of the slip clutch during tensioning.

    Abstract: Various methods and systems are provided below for the treatment of wastewater. According to various embodiments, treatment of wastewater is accomplished using the oxidative power of ozone gas and the interaction between ozone gas, FOGS, and large amounts of surfactants already present in wastewaters to be treated. According to various embodiments of the invention, a combination of oxidation, UV disinfection, and/or biological trickling filtration is used to provide a fact acting treatment for wastewater. These methods and systems generally enable reduced footprint in relation to the volumes treated, reduced cost, and increased efficiency. Various alternative embodiments are also disclosed.

    Abstract: Enzymes with modified substrate specificity and methods of obtaining same by the steps of a) determining the structure of two or more enzymes in the same group, b) comparing the structure of the substrate binding sites of the enzymes, and c) modifying selected amino acids by genetic mutation so that the substrate preference of one of the enzymes is altered. The methods are particularly useful for the stereospecific interconversion of oxyacids and aminoacids.

    Abstract: A method and a device are disclosed for reliably detecting fluid leaks while minimizing false alarms. A leak sensor in proximity of a flat leakage surface, such as a floor area, is used to sense a permittivity of a media, such as water, coming in contact with the leak sensor. Leak is indicated if the sensed permittivity exceeds a permittivity threshold within a predefined time period. The predefined time period indicates a rate threshold that if exceeded indicates relatively fast accumulation of fluid in an air gap between the leak sensor and the leakage surface, precluding or reducing the possibility of false alarm due to gradual increase in environmental humidity or moisture. The air gap defines a fluid volume that is substantially filled before leak is detected.
