  • Publication number: 20260167431
    Abstract: A package conveyor system has one or more accumulation sections (402). An accumulation section has conveyor rollers (502), first and second accumulation subsections (402A1, 402A2), a driven roller (518) positioned between the accumulation subsections, a drive belt (516), a selectably-activated motor (520), and at least one belt tensioning device (512). An accumulation subsection has movable frames (506), idler rollers (508, 510) held in place by the movable frames, and actuators (514) connected to the movable frames. The drive belt is in contact with the idler rollers, the belt tensioning device, and the driven roller, with the drive belt being urged into contact with a first set of conveyor rollers when a first actuator is in a first position, and removed from contact with the first set of conveyor rollers when the first actuator is in a second position. An accumulation subsection may be driven, free-rolling, or braked.

  • Patent number: 9027378
    Abstract: A digital manufacturing system comprises a build chamber, a build platform disposed within the build chamber, at least one extrusion line configured to heat a metal-based alloy up to a temperature between solidus and liquidus temperatures of the metal-based alloy, a deposition head disposed within the build chamber and configured to deposit the heated metal-based alloy onto the build platform in a predetermined pattern, an umbilical having a first end located outside of the build chamber and a second end connected to the deposition head, and at least one gantry assembly configured to cause relative motion between the build platform and the deposition head within the build chamber, where the at least one gantry assembly comprises a motor disposed outside of the build chamber.

  • Publication number: 20070014708
    Abstract: Apparatus and a method for collecting and redirecting liquid which has been separated from a gaseous process stream by inertial separation techniques such that the separated liquid and gaseous stream are flowing co-currently or counter-currently within the same process apparatus. The apparatus has liquid catch means, such as a flange, for catching the separated liquid and flow-through means, such as a flow-through opening in the flange, for simultaneously allowing the gaseous materials to flow, co-currently or counter-currently with the separated liquid, through and past the liquid catch means and downstream on to further processing equipment. The method comprises collecting the separate liquid phase by patching the separate liquid phase as it drips and flows down the inner wall of the process apparatus, while simultaneously allowing the gaseous materials to flow on, co-currently or counter-currently with the separate liquid phase, to further processing equipment, using the aforesaid apparatus.
