Abstract: A biological indicator reader is provided for reading a plurality of biological indicators to determine the effectiveness of at least a sterilization process. Each biological indicator is configured to exhibit fluorescence when the sterilization process has failed. Each reader comprises a housing having a plurality of biological indicator holders, a heater coupled to the housing and configured to heat the plurality of biological indicator holders to a preselected temperature to incubate the biological indicators, a UV light emitter configured to emit UV light through a first aperture on the side of each holder and an optical detector positioned under a second aperture on the bottom of the biological indicator holder, the optical detector configured to detect fluorescence intensity indicating the effectiveness of the sterilization process. A method of using the biological indicator reader is provided. A biological indicator system is also provided.

Abstract: A system that measures deviation of printed color at selected locations on a moving substrate from a target color. The system comprises using a printed test image of target color, a calibrated spectrophotometer to provide spectral response values of the target color on the test image, a photonic device that provides tri-stimulus values from inline printed images and a computing device. The computing device compares the tri-stimulus values to spectral response values for the test image to calculate a spectral transformation matrix at each location selected to remove variations in optical and mechanical parameters. The spectral transformation matrix is applied to future mapped sets of tri-stimulus values of printed colors captured by the photonic device from selected locations to determine in real-time the deviation of color and thereby control color quality.

Abstract: An energy supply system is provided with an electricity generating device for regeneratively generating electrical energy that can be fed into an electricity supply grid. The energy supply system includes an electricity generating device for regeneratively generating electrical energy which can be fed into an electricity supply grid, a hydrogen generating device for generating hydrogen using electrical energy from the regenerative electricity generating device, a methanation device for converting hydrogen generated by the hydrogen generating device and a supplied carbon oxide gas into a gas containing methane, and a gas providing device for providing a supplementary gas or a replacement gas in a variably specifiable supplementary/replacement gas quality suitable for feeding into a gas supply grid with the use of the gas containing methane from the methanation device and/or the hydrogen from the hydrogen generating device. A method of operating the system is also provided.

Abstract: A variable position gas trap apparatus and method to separate gases entrained in drilling fluid in a tank. The apparatus includes a gas trap attached to a carriage and a frame attached to the tank. A lever moveable by the float rod, activates the control valve to raise or lower the carriage having the gas trap container attached thereto. A feedback control loop is responsive to changes in the level of the drilling fluid in the tank. A mechanism is provided to mechanically and automatically move the carriage with respect to the frame in response to the feedback control loop.

Abstract: A process to analyze fluid entrained in well boreholes. The process includes gathering trap gas samples from return of drilling mud at multiple depths. The process also includes the steps of subjecting the samples to mass spectrometry in order to determine mass to charge ratios data of hydrocarbons and analyzing the mass to charge ratios data in relation to depth or time. Samples from at least one other source may also be gathered and analyzed chosen from the group consisting of mud fluid analysis, cuttings backgrounds analysis and cuttings crush analysis.
