  • Patent number: 11813619
    Abstract: A spray tip comprises a tip body, a tip piece, and a pre-orifice piece. The tip body has a fluid channel along a channel axis (AC). The tip piece is disposed within the fluid channel, and has a stepped, narrowing passage that terminates in an outlet orifice. The pre-orifice piece has an inlet passage, and is disposed within the fluid channel, abutting and immediately upstream of the tip piece. The pre-orifice piece and the tip piece together define a turbulating chamber therebetween.
    Type: Grant

  • Patent number: 10395166
    Abstract: Mipping systems and methods are disclosed. For example, a mipping system can include processing circuitry configured to receive combinations of a plurality of pixels N at a time, each pixel having material codes directed to respective materials of the pixels, where the material codes relate to infrared properties of the respective materials, and N is a positive integer greater than 1; and train an artificial neural network having a classification space by providing respective neurons for each unique combination of material codes, and condition the artificial neural network so that the respective neurons activate when presented with their unique of material code combinations in order to create a combined set of material code parameters for accurate rendering of the mipped pixels.

  • Patent number: 6705858
    Abstract: A rotary furnace includes a drum and a frame supporting the drum for rotation about a nominally horizontal rotational axis. The frame and the drum are supported for pivotal movement about a horizontal pivotal axis. A door supported on the frame normally closes the front end of the drum and is selectively pivotal to an open position to facilitate charging of the drum. The door includes a pouring door which is openable to facilitate discharge of molten material from the drum.
