  • Patent number: 11920016
    Abstract: This invention relates to thermoset, thermal insulating panel, pour-in-place and pour-in-place foams having desirable and unexpectedly low thermal conductivity, and to compositions, method and systems which use and/or are used to make such foams comprising: (a) providing thermosetting foam forming component and a blowing agent for forming predominantly closed cells in the foam, wherein the blowing agent comprises: (i) cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzzm(Z)) and cyclopentane, with the HFO-1336mzzm(Z) and cyclopentane in the blowing agent together comprising at least about 50% by weight of the total of all components in the blowing agent and (ii) the weight ratio of HFO-1336mzzm(Z) to cyclopentane in the blowing agent is from about 45:55 to less than 68:32 and (b) forming foam from said provided foamable composition.

  • Patent number: 10983505
    Abstract: Some embodiments facilitate creation of an industrial asset item via an additive manufacturing process wherein motion is provided between a build plate and a print arm. A correction engine may receive, from an industrial asset item definition data store containing at least one electronic record defining the industrial asset item, the data defining the industrial asset item. A correction engine computer processor may then correct the motion provided between the build plate and the print arm such that the motion deviates from a path indicated by the data defining the industrial asset item. The three-dimension printer may be a rotary printer such that the build plate rotates about a vertical axis and moves along the vertical axis during printing. In these cases, a pre-compensation algorithm may be applied to correct the motion provided between the build plate and the print arm before transmitting data to the three-dimensional additive manufacturing printer.

  • Patent number: 10698386
    Abstract: Some embodiments facilitate creation of an industrial asset item via a rotary additive manufacturing process. For example, a build plate may rotate about a vertical axis and move, relative to a print arm, along the vertical axis during printing. An industrial asset item definition data store may contain at least one electronic record defining the industrial asset item. A frame creation computer processor may slice the data defining the industrial asset item to create a series of two-dimensional, locally linear frames helically arranged as a spiral staircase of steps (and each step may be oriented normal to the vertical axis. Indications of the series of two-dimensional frames may then be output to be provided to a rotary three-dimensional printer.
