Abstract: A metal 3D printer is disclosed for fabricating metal articles by depositing molten metal onto a print bed. The metal 3D printer has a print head formed of a crucible and a nozzle. The crucible heats the molten metal and the nozzle deposits the molten metal onto the print bed. The 3D printer further includes an induction heating system to heat the print head and a heated print bed disposed below the nozzle. The metal 3D printer also comprises a computer numerically controlled (CNC) gantry configured to move the print head and the print bed relative to each other along X, Y, and Z axes. A shielding gas blower may direct a first stream of shielding gas proximate to the crucible and a second stream of shielding gas proximate to the nozzle. The feedstock for the printer may comprise a plurality of wire strands braided together. A mesh overlay may be positioned on top of the print bed.

Abstract: A satellite paint waste recovery system for a painting system which reduces hazardous waste generation, providing instead a plurality of solvent mixes which are reusable by the painting system. The satellite paint waste recovery system employs a method of capturing reusable solvent when changing paint colors in the painting system which includes flushing a discrete color of paint loaded in the painting system with fresh solvent and capturing the discrete color of paint flushed and some of the flushing solvent as a discrete color solvent mix in a discrete container each time the paint color sought to be used in the painting system is changed. The discrete color of solvent mix can subsequently be reused to thin a new container of paint instead of using new solvent.

Abstract: A circuit card assembly includes a first printed circuit board and a first electronic component mounted on the first printed circuit board. A heat transfer assembly is coupled to the first printed circuit board. The heat transfer assembly includes a first plate extending adjacent the first printed circuit board and a second plate extending adjacent the first plate. At least one of the first plate and the second plate includes an accommodation feature to accommodate the first electronic component. The heat transfer assembly further includes a first set of heat pipes between the first plate and the second plate. The first set of heat pipes is configured to remove heat from the first electronic component. At least one heat pipe of the first set of heat pipes extends adjacent the accommodation feature.

Abstract: Disclosed herein are systems and methods for the thermal regulation of on-board electronic components using a mezzanine filler module. The mezzanine filler module connects at a mezzanine site of the circuit board to provide an additional thermal conduction path for thermal energy released, at least, from component located under the mezzanine site.

Abstract: Systems and methods for authorizing a waste item to be removed from a site. In one embodiment, a waste collection vehicle includes a reader configured to obtain identification information from an identification tag associated with the waste item. A transceiver associated with the vehicle is configured to: receive the identification information from the reader, wirelessly transmit the identification information to a remote computer for processing, and wirelessly receive an indication of whether the waste item should be collected and removed by the waste collection. The received indication is based on at least one hazardous characteristic associated with the identified waste item, a determination that the waste collection vehicle is authorized to collect the waste item having the at least one hazardous characteristic, and a determination that a driver of the waste collection vehicle is authorized to collect the waste item having the at least one hazardous characteristic.

Abstract: System and methods for identifying waste items in a waste management environment includes reading data from a plurality of identifiers that are attached to waste items. The read data is compared with reference data stored in one or more data repositories. If a match exists between any of the read data and the reference data, an indication of non-compliance of the waste item with predetermined safety criteria is provided.

Abstract: A pigment composition containing titanium dioxide (TiO.sub.2) and calcined clay in a weight ratio of between about 30:70 and 70:30, preferably between about 35:65 and 45:55 that is substantially free of a functional microgel component has advantages over a similar pigment containing a functional microgel. The pigment composition contains an amount of epichlorohydrin dimethylamine condensate that is sufficient to cationize the pigment, and lacks a microgel component. It is liquid when agitated. Preferably the composition has a solids content greater than about 55%, and most preferably between about 59% and about 61%.
