Abstract: A vacuum may include a housing, a filter, a motor-fan assembly, and a flue. The housing defines a chamber having a circular cross-section. The filter may have an annular shape and is disposed in the chamber of the housing. The motor-fan assembly includes a motor drivably coupled to a fan, such that the fan is mounted above the motor. The motor and the fan are enclosed in a casing, and the casing is disposed in an opening of the filter. The fan draws air into the chamber via the intake port and upward through the filter into the casing of the motor-fan assembly. The flue defines an exhaust path from the casing to the exhaust port, whereby air drawn into the casing is discharged via the flue outside the chamber of the vacuum.

Abstract: A system and method for anomaly detection is provided. The system (100) and method (200) include utilizing one or more processors, such as in a server, for receiving (108) operational and dynamics data (104) from sensors associated with devices (102), filtering the data, establishing a set of baseline dynamics data and eliminating data dependencies (110). The system and method further include generating an expected level of data variation (112), identifying an anomaly based on a deviation of the device data from the baseline data normalized by the expected level of data variation (114), optionally correlating an anomaly with potential causes, and providing an output indicating an anomaly (116).

Abstract: A sequentially pulsed traveling wave compact accelerator having two or more pulse forming lines each with a switch for producing a short acceleration pulse along a short length of a beam tube, and a trigger mechanism for sequentially triggering the switches so that a traveling axial electric field is produced along the beam tube in synchronism with an axially traversing pulsed beam of charged particles to serially impart energy to the particle beam.

Abstract: An apparatus for shielding a stream of molten metal during teeming consisting of a pair of cylinders aligned on a common axis by means adapted to position one cylinder against a ladle around the pouring spout and the second cylinder proximate a tundish, ingot mold or pouring trumpet. Also included are means to form a gas barrier between the cylinders to contain a shielding (inert) gas around the molten metal stream to protect the stream from contact by the ambient atmosphere and means to mount the apparatus on a pouring ladle carriage.
