Abstract: Embodiments of the present invention comprise a signal processing method and apparatus for use in a satellite payload in which an input RF signal received at a receiver antenna is modulated by using a single optical carrier at the input of an optical modulator. The optical domain signal is processed and is subsequently combined with a single unmodulated optical LO tone to provide an output RF signal for radiation by a transmitter antenna or for further digital processing by an on-board processor. This results in a clean generation of the frequency-converted RF signal at the output of the opto-electrical conversion stage.

Abstract: A process and an apparatus for building tyres, wherein, in the process, a carcass sleeve including at least one carcass ply and a pair of annular anchoring structures is transferred to a shaping drum including flange elements that are each engageable with one of said annular anchoring structures. The carcass sleeve is shaped according to a toroidal configuration. Before shaping, annular grip elements respectively carried by the flange elements are radially expanded, each inside one of the annular anchoring structures, in order to engage the carcass sleeve. The annular anchoring structures are moved axially apart from each other before engaging the carcass sleeve by the annular grip elements.

Abstract: Automated systems and methods for obtaining of the concentration of impurities in a liquid ethylene oxide product stream are shown and described. The systems and methods employ remote injection and flash vaporization of small volumes of liquid ethylene oxide into a carrier gas to minimize polymerization of the ethylene oxide and accumulation of polymerized ethylene oxide. Ethylene oxide peaks are diverted from the gas chromatograph effluent detector to stabilize baseline signal errors and avoid errors in the calculation of an impurity with an adjacent retention time peak. The systems and methods may be used for feedback, feedforward, dynamic matrix, and/or model-based predictive control of ethylene oxide purity. The systems and methods reduce lag times and errors associated with relying on laboratory analyses to make process adjustments.

Abstract: A portion of a wellbore is put into communication or is isolated by selectively applying an axial or rotational force downhole. The axial force moves a shifting sleeve and deployment sleeve from an initial position to an opening position causing a valve element to move into an open configuration and allowing communication to the portion of the wellbore. The shifting sleeve is returned to the initial position and separated from the deployment sleeve, which is anchored to a retraction sleeve adjacent the valve element. Threads on the shifting and retraction sleeves become engaged when the deployment sleeve is moved to the opening position. The retraction sleeve is rotated by rotating the shifting sleeve, threaded engagement with the rotating retraction sleeve draws the deployment sleeve away from the valve element, and allows the valve element to move to a closed configuration.
