  • Patent number: 10442118
    Abstract: To better control part quality of 3D printed parts, the temperature of an extruder filament using a secondary heat source is provided. A heat source, such as an infrared heat source, can be used to heat the filament of a 3D printer to the optimum temperature that will enhance welding of the filament to a substrate that it is being printed on or to. Such an optimum temperature can be based upon, in part, the temperature of the substrate. A controller or other intelligent control can be used to receive temperature readings of the substrate and/or filament and then can adjust the temperature of the heating source to optimize the temperature of the filament to better combine the filament to the substrate.

  • Patent number: 10434083
    Abstract: Methods for transmammary administration of an analgesic to offspring swine are disclosed, which are useful for mitigating, inhibiting, and/or reducing pain in offspring swine prior to undergoing processing procedures that would cause or result in pain. The methods generally comprise administering, via injection, a cyclooxygenase-2 inhibitor class analgesic directly to a lactating female swine. The analgesic is passed indirectly to the offspring swine through the milk of the treated lactating female swine and has beneficial effects, including increases in weight gain, performance, and decreases in pain. A single dosage form injected into the lactating female is suitable for achieving indirect therapeutically effective levels of the cyclooxygenase-2 inhibitor class analgesic in the milk for the offspring.

  • Patent number: 10391503
    Abstract: A system and method for predicting a future wind direction and speed and, based thereon, determining a future wind-driven drift and providing the information to an operator or automatically acting to adapt application parameters to better control the wind-driven drift of a fluid during application of the fluid to land or crops by an agricultural machine. A processor receives machine and meteorological data, uses a model to predict the future wind direction and speed, and accesses a drift distance database to determine and visually depict the future wind-driven drift of the fluid. A sensitive area database stores information about sensitive areas bordering the target area, which may also be displayed, to facilitate controlling the wind-driven drift with regard to the sensitive areas. The mathematical model may be a kernel filter, an autoregressive model, an autoregressive integrated moving average model, or a hybrid model which incorporates features of different models.

  • Patent number: 10351430
    Abstract: A method, apparatus, and system for fabricating buckypaper or similar sheets of nanostructures having relatively high aspect ratios. A dispersion of nanostructures such as nanotubes is subjected to fluid dynamics/forces which promote alignment of their axes of elongation while in suspension in the flow. An agglomeration of better aligned nanostructures is isolated from the carrier fluid into a useable form. In the case of nanotubes, one form is buckypaper. One example of alignment forces is Taylor-Couette flow shear forces. One example of isolation is filtering the flowing dispersion to collect better aligned nanostructures across the filter into a sheet or film. The degree of alignment can produce anisotropic material properties that can be beneficially used in application of the sheet or film.
