  • Patent number: 10155398
    Abstract: A direct-to-object printer includes an image projector that projects an image on an object secured in a holder before the holder and the object pass a plurality of printheads for printing an ink image on the object. A camera generates a sequence of images of the projected image on the object to enable an operator to select a position on the object for the printing of the image and to identify distortion in the image through a user interface so a controller can modify operation of the printheads to attenuate the distortion in the image printed on the object.

  • Patent number: 8747956
    Abstract: Processes, systems, and apparatuses are disclosed for forming products from atomized metals and alloys. A stream of molten alloy and/or a series of droplets of molten alloy are produced. The molten alloy is atomized to produce electrically-charged particles of the molten alloy by impinging electrons on the stream of molten alloy and/or the series of droplets of molten alloy. The electrically-charged molten alloy particles are accelerated with at least one of an electrostatic field and an electromagnetic field. The accelerating molten alloy particles are cooled to a temperature that is less than a solidus temperature of the molten alloy particles so that the molten alloy particles solidify while accelerating. The solid alloy particles are impacted onto a substrate and the impacting particles deform and metallurgically bond to the substrate to produce a solid alloy preform.

  • Publication number: 20140141236
    Abstract: Paint formulations having a high absorptivity with respect to solar radiation are disclosed herein. The disclosed paint formulations are also thermally and mechanically durable, thereby enabling the paint formulations to be used on components in solar thermal applications where exposure to high temperatures and environmental conditions may be an issue. The paint formulation can include an oxide-based pigment, an organic binder, one or more additives, an inorganic filler, and/or an organic solvent. The pigment can have a relatively high absorptivity with respect to light having a wavelength in the range from 250 nm to 3000 nm. Curing of the paint formulation can irreversibly convert the organic binder into an inorganic binder.
