Abstract: A computer-implemented method, executed by one or more email detection computers, receives from a computer network, a first email message from a first sender account to a first recipient account and having a plurality of attributes. The method determines that the first email message is a phishing email, extracts a subset of attributes, normalizes transformable attributes, and generates a hash representation from fixed attributes and the normalized transformable attributes, stores the hash representation in a database, receives a second email message, and determines that the second email message is a phishing email based on the stored hash representation.

Abstract: A method includes receiving, from a pre-processor, an output file, the output file having been created by the pre-processor in response to input of an electronic file to the pre-processor, the electronic file being an attachment to an electronic mail message that is in-transit to a recipient computer on a network, the electronic file being a spreadsheet file, the output file containing features that are created by the pre-processor; receiving, from a machine learning-based classifier, malware classification data, the malware classification data being output by the machine learning-based classifier in response to the machine learning-based classifier determining whether the features are indicators of obfuscation, the data used to create the machine learning-based classifier including output files previously created by the pre-processor; in response to the malware classification data matching a criterion, causing the network to modify, delay, or block transmission of the electronic file to the recipient compute

Abstract: An apparatus for separating hot particles including a plurality of materials having different magnetic properties includes a plurality of permanent magnets arranged in a magnet assembly and configured to create a magnetic flux capable of providing a coercive force on at least a portion of the particles, the magnet assembly being mounted on a stationary shaft, a moving surface proximate the magnet assembly for carrying the particles in a downward path through the magnetic flux while the coercive force attracts the portion of the hot particles toward the moving surface, the moving surface being mounted on a drive shaft supported by a bearing, and an inert gas supply system which supplies inert gas into a gap between the stationary shaft and the drive shaft for cooling the drive shaft and the bearings, and into the magnet assembly for purging the magnet assembly of oxygen.

Abstract: A drive system for an apparatus separating hot particles being received by a moving surface includes a drive shaft for driving the moving surface receiving the hot particles, a drive unit for rotating the drive shaft, and a flexible coupling arranged between the drive shaft and the drive unit. The flexible coupling includes thin portions defining a portion of a heat transfer path from the drive shaft to the drive unit. The thin portions have large surface area to volume ratios for extending the heat transfer path. The thin portions dissipate heat when the flexible coupling is driven by the drive unit.
