Abstract: Additive manufacturing's reliance on embedded computing renders it vulnerable to tampering through cyber-attacks. Sensor instrumentation of additive manufacturing devices allows for rigorous process and security monitoring, but also results in a massive volume of noisy data for each run. As such, in-situ, near-real-time anomaly detection is challenging. A probabilistic-model-based approach addresses this challenge.

Abstract: A pallet and method for supporting a spool for transport or use includes an elongated frame having two opposite ends and two opposite sides which extend between the two opposite ends. The frame includes a support surface within which a spool can be cradled so that the spool rests across the support surface and the barrel of the item is oriented substantially horizontally and normal to the longitudinal axis of the frame. A pair of cooperating members are arranged adjacent the sides of the frame and are cooperable with the spool barrel for placing a spool in condition to be lifted from the support surface. Jack assemblies are interposed between the cooperating members and the frame for lifting the spool from the support surface by way of the jack assemblies.

In addition, an abutment surface is associated with the upwardly-opening pocket for aiding in the locating of an end portion of the axle assembly in vertical registry with the upwardly-opening pocket, and the upwardly-opening pocket includes a pair of spool-centering guide plates along the side opening thereof.

Abstract: High quality, catalyst-free boron nitride nanotubes (BNNTs) that are long, flexible, have few wall molecules and few defects in the crystalline structure, can be efficiently produced by a process driven primarily by Direct Induction. Secondary Direct Induction coils, Direct Current heaters, lasers, and electric arcs can provide additional heating to tailor the processes and enhance the quality of the BNNTs while reducing impurities. Heating the initial boron feed stock to temperatures causing it to act as an electrical conductor can be achieved by including refractory metals in the initial boron feed stock, and providing additional heat via lasers or electric arcs. Direct Induction processes may be energy efficient and sustainable for indefinite period of time. Careful heat and gas flow profile management may be used to enhance production of high quality BNNT at significant production rates.
