  • Patent number: 10732609
    Abstract: Methods and apparatus to produce fluid control device components are related fluid control devices. An example method of producing a valve component, includes: accessing a first request from a user interface device to produce a valve component, the first request specifying first characteristics of the valve component; when the first characteristics are not associated with a first build file, comparing the first characteristics to first reference characteristics to determine if the first characteristics satisfy a threshold; if the first characteristics do not satisfy the threshold, providing feedback accessible at the user interface device to change the first characteristics to second characteristics, where the second characteristics satisfy the threshold; and when the first characteristics are associated with the first build file or when the first or second characteristics satisfy the threshold, causing, using the one or more processors, an additive manufacturing machine to produce the valve component.

  • Patent number: 10639705
    Abstract: A method of fabricating a finished part includes generating or creating a master pattern using an additive manufacturing process, and the master pattern corresponds in shape to the finished part. A shell is created by applying one or more layers of one or more coating materials to the master pattern. The master pattern is then dissolved while the master pattern is in the shell to create a cavity in the shell that corresponds in shape to the finished part. A molten material is then poured into the cavity of the shell. The molten metal is allowed to cool and to harden and/or to reach a determined temperature such that the molten metal becomes the finished part. The shell is then removed from around the finished part.

  • Patent number: 10619760
    Abstract: Securing communications from a process plant to a remote system includes a data diode disposed there between that allows data to egress from the plant but prevents ingress of data into the plant and its associated systems. Process plant data from the secure communications is then analyzed to detect conditions occurring at process plant entities in the process plant using various machine learning techniques. When the process plant entity is a valve, the mode of operation for the valve is determined and a different analysis is applied for each mode in which a valve operates. Additionally, the process plant data for each valve is compared to other valves in the same process plant, enterprise, industry, etc. Accordingly, the health of each of the valves is ranked relative to each other and the process plant data for each valve is displayed in a side-by-side comparison.
