  "abstract": "A tool for inserting a flame arrestor assembly into a process control device having a first passageway of a first depth and a second passageway of a second depth different from the first depth. The tool includes a head portion having a first diameter, and a tip portion having a second diameter less than the first diameter. The tip portion has a first portion, a second portion, and a third portion, the first and second portions being separated by a first notch, and the second and third portions being separated by a second notch. The first notch is arranged to indicate when the flame arrestor assembly is fully inserted into the first passageway, and the second notch is arranged to indicate when the flame arrestor assembly is fully inserted into the second passageway.",
  "claims": [
    "1. A system, comprising: a process control device having a first passageway of a first depth and a second passageway of a second depth different from the first depth; a flame arrestor assembly; and a tool for inserting the flame arrestor assembly into the process control device, the tool comprising: a head portion having a first diameter; and a tip portion having a second diameter less than the first diameter, the tip portion having a first portion, a second portion, and a third portion, the first and second portions being separated by a first notch, and the second and third portions being separated by a second notch, wherein the first notch is arranged to indicate when the flame arrestor assembly is fully inserted into the first passageway, and wherein the second notch is arranged to indicate when the flame arrestor assembly is fully inserted into the second passageway.",
    "2. The system of claim 1, wherein the head and tip portions are made of Stainless Steel.",
    "3. The system of claim 1, wherein the tool has a first end and a second end opposite the first end, the first portion of the tip portion including the first end, and the head portion including the second end.",
    "4. The system of claim 1, wherein the first end of the tool is chamfered.",
    "5. The system of claim 1, wherein the first end of the tool is flat.",
    "6. The system of claim 1, wherein two or more of the first, second, and third portions have the same diameter.",
    "7. The system of claim 1, wherein the first, second, and third portions have different diameters.",
    "8. The system of claim 1, further comprising a bore partially extending through the tip portion.",
    "9. A system, comprising: a process control device having a first passageway of a first depth and a second passageway of a second depth different from the first depth; a flame arrestor assembly; and a tool for inserting the flame arrestor assembly into the process control device, the tool comprising: a head portion having a first diameter; and a tip portion having a second diameter less than the first diameter, the tip portion having a first portion and a second portion, the first portion having a first length selected based on the first depth, the second portion having a second length selected based on the second depth.",
    "10. The system of claim 9, wherein the first length is selected to correspond to the flame arrestor assembly being fully inserted into the first passageway, and the second length is selected to correspond to the flame arrestor assembly being fully inserted into the second passageway.",
    "11. The system of claim 9, wherein the head portion has a length greater than a sum of the first and second lengths.",
    "12. The system of claim 9, wherein the first and second portions have the same diameter.",
    "13. The system of claim 9, wherein the first and second portions have different diameters.",
    "14. The system of claim 9, wherein the tool has a first end and a second end opposite the first end, the first portion of the tip portion including the first end, and the head portion including the second end.",
    "15. The system of claim 14, wherein the first end is chamfered.",
    "16. The system of claim 14, wherein the first end is flat.",
    "17. The system of claim 9, further comprising a bore partially extending through the tip portion.",
    "18. A system, comprising: a flame arrestor assembly; a process control device having a first passageway of a first depth and a second passageway of a second depth different from the first depth; and an assembly for inserting the flame arrestor assembly into the process control device, the assembly comprising: a tool comprising: a head portion having a first diameter; and a tip portion having a second diameter less than the first diameter, the tip portion having a first portion and a second portion, the first portion having a first length selected based on the first depth, the second portion having a second length selected based on the second depth; and a guide element having a base, a collar extending outward from the base, and a guide bore extending through the base and the collar, the collar having a threaded portion arranged to engage a corresponding threaded portion of the first or second passageway, and the guide bore sized to receive the tip portion of the tool, thereby guiding the tool into the first or second passageway.",
    "19. The system of claim 18, wherein the base has an outer diameter that is greater than an outer diameter of the collar.",
    "20. The system of claim 18, further comprising a bore partially extending through the tip portion of the tool."

  "description_excerpt": "The present disclosure is directed to a tool for flame arrestor assemblies, and, more particularly, to a tool for inserting components of a flame arrestor assembly into fluid flow passageways of a process control device having different depths.\n\nProcess control devices, e.g., valve controllers, may be operated in environments that are susceptible to explosions or fires. For example, valve controllers may control valves that control oil flow in a refinery or the flow of chemicals in a chemical plant or manufacturing facility. Valve controllers typically include modules having an enclosure that may accumulate fluids and/or gases from the potentially combustible environments. Sparks or overheating by electronics, wiring, or motors within the modules may ignite a fluid inside the module and initiate a flame, a fire, or an explosion. Because, in many cases, the modules include passages or channels that enable a fluid to flow between the outside of the enclosure or housing and the inside of the enclosure or housing to enable electronics of the module to measure properties of the fluid, there exists the risk that a flame, a fire, or an explosion initiated within the module will spread, via the passages or channels, to the potentially combustible environment outside the module.\n\nTo prevent such a flame, fire, or explosion from spreading from the module to the potentially combustible outside environment, a flame arrestor may be disposed within a channel or a passage of the module.",
