Publication number: 20240142052Abstract: A rotary multiport greasing valve having an outer sleeve and an inner sleeve within the outer sleeve. The outer sleeve has at least one inlet port and at least 2 outlet ports. The inner sleeve has an inlet port, a central passageway, and an outlet port. The inner sleeves inlet port is fluidly connected to the outer sleeve's inlet port. The inner sleeve rotates within the outer sleeve so that the inner sleeves outlet port is circumferentially aligned with a selected outer sleeve outlet port creating a fluid pathway from the outer sleeve inlet port into the inner sleeve's inlet port through the central passageway through the inner sleeve's outlet port and finally through the outer sleeves outlet port to create an open flowpath. In certain instances, the inner sleeve inlet port is longitudinally shifted so as not to align with any portion of an outlet sleeve outlet port.Type: ApplicationFiled: January 8, 2024Publication date: May 2, 2024Applicant: Patriot Research Center, LLC (DBA Atlas Pressure Control)Inventors: Craig Cotton, Brandon Cain

Publication number: 20240068617Abstract: A check valve bleed assembly eliminates the requirement for a person to enter the red zone when bleeding the grease out of a gate or other valve. A gas or other fluid is provided to the check valve bleed assembly. The gas or other fluid acts upon the surface driving a pin into the associated check valve with sufficient force to overcome the resistance of the object sitting on a seat and moves the object off of the seat. The force is maintained as long as is necessary. Usually, the check valve is held open until the gate transitions into the gate's associated gate recess thereby displacing the grease within the gate recess through the check valve, into the check valve bleed assembly, and finally to a waste collection tube. In some embodiments a gate valve greasing access port is included in the check valve bleed assembly such that grease may be injected into the check valve bleed assembly.Type: ApplicationFiled: October 25, 2023Publication date: February 29, 2024Applicant: Patriot Research Center, LLC (DBA Atlas Pressure Control)Inventors: Craig Cotton, Manish Agarwal, Joseph Opitz

Publication number: 20230175337Abstract: An isolation tool is provided that includes an upper elastomer, a lower elastomer. The isolation tool when set provides a circumferential flow path between the elastomers. The isolation tool also includes a longitudinal flow path from above the isolation tool to below the isolation tool. The longitudinal flowpath is preferably sufficiently linear that a solid tool may be passed through the longitudinal flowpath from above the isolation tool to below the isolation tool.Type: ApplicationFiled: December 7, 2021Publication date: June 8, 2023Applicant: Patriot Research Center, LLC (DBA Atlas Pressure Control)Inventors: Craig Cotton, Brandon Cain

Publication number: 20220186583Abstract: A greasing system may be placed partially within the red zone and partially outside of the red zone. Grease and pneumatic power is supplied from outside of the red zone to a pod, inside of the red zone, having local storage, high-pressure pumping capacity, and a distribution mechanism. The grease is supplied from outside of the red zone to the pod at low-pressure through a hose having at least a 1 inch inside diameter and is usually at least 100 feet long. The pod pressurizes the grease to a high-pressure and distributes the grease via a distribution mechanism to a relatively short hose, generally less than 8 feet between the distribution mechanism and the greasing point on the wellhead, in order to minimize pressure losses.Type: ApplicationFiled: December 10, 2020Publication date: June 16, 2022Applicant: Patriot Research Center, LLC (DBA Atlas Pressure Control)Inventors: Brandon Cain, Joseph Opitz, Manish Agarwal, Michael Pursley

The outer sleeve has at least one inlet port and at least 2 outlet ports. The inner sleeve has an inlet port, a central passageway, and an outlet port. The inner sleeves inlet port is fluidly connected to the outer sleeve's inlet port. The inner sleeve rotates within the outer sleeve so that the inner sleeves outlet port is circumferentially aligned with a selected outer sleeve outlet port creating a fluid pathway from the outer sleeve inlet port into the inner sleeve's inlet port through the central passageway through the inner sleeves outlet port and finally through the outer sleeves outlet port to create an open flowpath. In the instance where a closed flowpath is desired the inner sleeve inlet port is rotated so as not to align with any portion of an outlet sleeve outlet port.Type: ApplicationFiled: March 1, 2021Publication date: June 16, 2022Applicant: Patriot Research Center, LLC (DBA Atlas Pressure Control)Inventors: Craig Cotton, Brandon Cain

Publication number: 20220082178Abstract: A sensor system to indicate whether or not the gate valve is open, closed, or at some position between. In certain instances, two sensors may be used to indicate the position of an attachment to the gate within the gate valve thereby indicating whether or not the gate within the gate valve is fully opened or fully closed. In other instances, a single sensor may be utilized to indicate the position of an attachment to the gate within the gate valve such position being between and including fully opened and fully closed. Generally, a sensor which may include both an emitter and receiver, is affixed externally of the pressurized portion of the gate valve or other type of valves.Type: ApplicationFiled: March 26, 2021Publication date: March 17, 2022Applicant: Patriot Research Center, LLC (DBA Atlas Pressure Control)Inventors: Brandon Cain, Manish Agarwal
