摘要： A system for scheduling, changing, and maintaining an outage schedule includes a data entry module adapted to allow a user to enter data pertaining to an outage, a pre-defined database containing transaction rules to define transaction flows, a processing module, and a display module. The processing module is adapted to process the data entered into the data entry module and the transaction rules provided in the pre-defined database. The display module receives processed data from the processing module, transforms the processed data into visual information representative of the processed data, and displays the visual information on a display of a computing device.

摘要： In an apparatus for electroslag welding of steel sheets with the aid of at least one wire electrode pair, a welding gap defined between the electrodes of the electrode pair, current-carrying conduits for the electrode pair, and a supply tube for supplying metal in a powdered state, and welding flux into the welding gap, the improvement includes a shielding device creating a duct along the current-carrying conduits. The duct, owing to the shielding device, is substantially free of any magnetic field, and the supply tube is positioned in the duct.

摘要： A frequency division, energy comparison signal processing system for detecting the presence of, and separating the contributions from, sources that compose a wide-band sound signal, in which the system divides at least part of the wide-band sound signal into a number of discrete narrow frequency band components, generates the energy envelope of each of those components, normalizes the envelopes, multiplies each normalized envelope with each of the other normalized envelopes to obtain a plurality of envelope correlation coefficients for each frequency band, and then identifies from the correlation coefficients a sound source seed frequency band component and then, using the seed, identifies the remaining frequency components of a sound source.

摘要： An apparatus for safeguarding a welding pool in mechanized welding in a constrained position, for example a vertical position, comprises sliding blocks pressed against the surfaces of the work pieces to be welded and supplying the welding current and the welding electrode and moving at the welding rate. The sliding blocks comprise two segments which are closely adjacent in the perpendicular center plane of the welding gap between the work pieces and are mutually movable. The sliding block segments are pressed in a yielding manner against the surface of each work piece and are individually and independently movable.
