Publication number: 20240092036Abstract: A pipe fusion machine including a track mounted chassis supporting a horizontal turntable for unlimited, reversible rotation relative to the chassis. A boom pivotally attached at a rear end of, and extending forwardly of, the turntable enables manipulation of elevations and distances of the free end of the boom. The free end of the boom is adapted to permit pivotal mounting thereon of a pipe fusion tool such as an indexer configured to articulate and support a pipe-end facer and a pipe-end heater for respective independent orientation into and out of alignment with the ends of pipes to be fused. A carriage supports fixed and sliding jaws adapted to grip the ends of pipes to be fused for relative reciprocal movement during a pipe fusion process. Each of the jaws may include an upper half jaw and lower left and right quarter jaws.Type: ApplicationFiled: September 20, 2023Publication date: March 21, 2024Inventors: Arthur H. McElroy, II, Paul John Donaldson, Eric R. Abbott, Seth P. Ahrens, Douglas K. Brownell, Gregory A. Ruoff, Jared D. Sparks, Matthew A. Price

Patent number: 11034039Abstract: A facer facing the ends of polyolefin pipes for butt fusion is modular in the sense that it employs three types of modules, a drive unit, two blade holders and a motor assembly, that are separable from one another and each independently light enough to be hand-lifted along walls and up to ceilings. The drive unit module is adjustable to accommodate different guide rail spacings. The blade holder modules are interchangeable to accommodate different diameters of pipe. The motor assembly module has multispeed capability to accommodate the total area of material to be faced. Each module can be exchanged or modified without use of tools to change the geometry of the assembled facer to accommodate different fusion machines and/or diameters of pipe within working spaces dictated by the diameter of the pipe and not by a fixed geometry of a facer.Type: GrantFiled: June 8, 2020Date of Patent: June 15, 2021Inventors: Timothy M. Thoman, Arthur H. McElroy, II, Paul John Donaldson, Brian M. O'Connell

Patent number: 10953534Abstract: Handheld power tools are adapted for magnetic stabilization based on the incorporation of one or more permanent magnets in a base thereof. One or more permanent magnets may be incorporated into the base of a handheld power tool (or a detachable rechargeable battery base) such that when the base is contacted with an inclined steel roof panel, a magnetic force is applied that is sufficient to secure the handheld power tool in an upright and non-operational configuration. The distal region of the base may include a spacer formed from a compliant material to provide a spatial offset between the one or more permanent magnets and a surface with which the base is contacted. In some example embodiments, a rechargeable battery pack may include one or more permanent magnets that are capable of supporting the weight of an associated charger when the battery pack is contacted with a vertical steel surface.Type: GrantFiled: June 29, 2018Date of Patent: March 23, 2021Inventor: Trevor John Donaldson

Publication number: 20160378928Abstract: Therapist assisted mental health management systems, processes and methods using a therapist remote therapy management computer in communication with a therapy central system cloud for storing plural queued learning modules corresponding to each of one or more different clients. A video conference system allows for confidential video consultation between a mental health therapist and one or more different clients (patients). The client (patient) communicates with the therapy central system cloud to access queued confidential learning modules from the therapy central system cloud. The systems, processes and methods can use interactive, educational treatment modules and periodic consultations with a counselor (therapist). The processes, methods and system can be viewable on a smart phone, tablet, and a computer. The methods, processes and systems can collect analytics on the performance of materials, exercises, and user experiences to continuously improve the system over time.Type: ApplicationFiled: September 12, 2016Publication date: December 29, 2016Inventors: Sheryl A.
