  • Patent number: 10946465
    Abstract: One aspect of the disclosure provides an iron-based hardfacing layer which includes hard or wear resistant phases resulting at least in part from dissolution of silicon and/or boron carbide particles into a liquid iron-based metal during the fabrication process. In an embodiment, the hardfacing layer is formed by a fusion welding process in which carbide particles are added to the molten weld pool. In an example, the filler metal supplied to the welding process is a mild steel. In an embodiment, the hardness as measured at the surface of the hardfacing ranges from 40 to 65 HRC. In an example, the iron-based hardfacing layer also includes tungsten carbide particles.

  • Patent number: 9802201
    Abstract: In one embodiment, a bale processor includes a hopper for receiving baled material, a discharge opening for outputting chopped material, and primary and secondary rotors. The primary rotor has an axis of rotation and a rotatable flail to chop the material from the bale received in the hopper. The secondary rotor is rotatable to chop the material after being chopped by the primary rotor, and the secondary rotor is offset from the primary rotor such that the primary rotor is between the secondary rotor and the discharge opening. The flail includes a pivot tube for rotating about the axis, first and second hammers secured to the pivot tube, and a paddle. The paddle is positioned between and secured to the first and second hammers to generate airflow when the first and second hammers are rotated at an operating speed, thereby increasing a throw distance of the chopped material.

  • Patent number: 9728667
    Abstract: A device that detects single optical and radiation events and that provides improved blue detection efficiency and lower dark currents than prior silicon SSPM devices. The sensing element of the devices is a photodiode that may be used to provide single photon detection through the process of generating a self-sustained avalanche. The type of diode is called a Geiger photodiode or signal photon-counting avalanche diode. A CMOS photodiode can be fabricated using a “buried” doping layer for the P-N junction, where the high doping concentration and P-N junction is deep beneath the surface, and the doping concentration at the surface of the diode may be low. The use of a buried layer with a high doping concentration compared to the near surface layer of the primary P-N junction allows for the electric field of the depletion region to extend up near the surface of the diode. With a low doping concentration through the bulk of the diode, the induced bulk defects are limited, which may reduce the dark current.

  • Publication number: 20160288239
    Abstract: Arc welding systems, apparatus and methods are for hardfacing are provided, including particle feeding apparatus. In one aspect the workpiece is moved in an oscillatory fashion while keeping the welding torch and the particulate delivery system stationary during at least a portion of welding pass. The welding torch and particulate delivery system may also be moved in a non-oscillatory fashion. Process speeds of about 18-30 in/min can be obtained with carbide incorporation of greater than 30% and uniform distribution.
