Abstract: Embodiments of the disclosure provide a method for controlling steam pressure within a turbine component. The method includes calculating a predicted stress on a rotor of the turbine component based on a predicted steam flow with the inlet valve in a minimum load position, a rotor surface temperature, and an inlet steam temperature, and determining whether the predicted stress exceeds a threshold. If the predicted stress exceeds the threshold, the inlet valve adjusts to a warming position. When steam in the discharge passage reaches a target pressure, the exhaust valve partially closes while maintaining the warming position of the inlet valve. If a safety parameter of the turbine component violates a boundary, the exhaust valve partially opens while maintaining the warming position of the inlet valve. When the predicted stress does not exceed the threshold, the inlet valve opens to at least the minimum load position.

Abstract: A mass spectrometer comprises an ion detector, an analog-to-digital (A/D) converter, a sample adjuster, and an adder. The A/D converter is configured to generate digital samples representing an analog signal received from the ion detector during a mass scan. The adder is configured to sum the samples with corresponding unsuppressed samples representing analog signals received from the ion detector during previous mass scans, the summed samples defining a mass spectrum. The sample adjuster is configured to identify a peak defined by the samples and to suppress all but one of the samples defining the identified peak to enhance resolution of a peak in the mass spectrum.

Abstract: A mass spectrometer includes an ion detector, an analog-to-digital (A/D) converter, and a decimator. The analog-to-digital (A/D) converter is configured to receive and sample an analog signal from the ion detector thereby providing a first plurality of samples at a first rate. The decimator is configured to receive the first plurality of samples and to transmit, at a second rate, a second plurality of samples that are based on the first plurality of samples. The decimator is further configured to dynamically adjust the second rate so that memory requirements for the mass spectrometer are reduced.

Abstract: A mass spectrometer comprises an ion detector, a first amplifier, a second amplifier, and a spectra combiner. The ion detector is configured to generate an analog signal indicative of ions detected by the ion detector. The first amplifier is configured to amplify the analog signal to provide a first amplified signal having a first gain relative to the analog signal. The second amplifier is configured to amplify the analog signal to provide a second amplified signal having a second gain relative to the analog signal, and the first gain is different than the second gain. The spectra combiner is configured to combine first summed digital samples of the first amplified signal with second summed digital samples of the second amplified signal.

Abstract: Apparatus for wet laminating a photopolymerizable film onto circuit board panels or other substrates. The apparatus is easily and quickly convertible from dry laminating to wet laminating with the rollers therefor mounted in bearing blocks which are insertable in slots in brackets at each end and removable therefrom. The lower roller thereof has a gear the teeth of which are meshable with the teeth of an idler gear for transmission of rotation power thereto. Elongate tubes for applying a fluid, which comprises between about 0.1 and about 10 wt. % of a heterocyclic metal-chelating agent, to the wet insertion rollers for application thereof to the panels are contained in a yoke which is adjustable next to wet insertion rollers for wet laminating or away from dry insertion rollers for dry laminating.
