Publication number: 20240311733Abstract: Computer readable instructions for operations that cause a processor to receive, by a remote recommendation server, a request comprising requestor information characterizing a site of a plurality of sites. The operations cause the processor to receive, by a site database, the requestor information, wherein the site database stores historical data characterizing the plurality of sites over time. The operations also cause the processor to receive, a recommendation engine, the requestor information and generate, by the recommendation engine, a set of plans to curtail the carbon footprint of the site based on the requestor information. The operations further cause the processor to simulate, by the recommendation engine, execution of the set of plans to curtail the carbon footprint of the site and select, by the recommendation engine, a plan of the set of plans to curtail the carbon footprint of the site.Type: ApplicationFiled: March 15, 2023Publication date: September 19, 2024Inventors: Mario Daniel Ibanez, David W. Abel, Stephan Ulrich Nitsche, Michael J. Haass

Publication number: 20240269805Abstract: A drilling machine having a three jaw system on each of two wrench assemblies, for gripping and rotating a pipe. Each wrench assembly has a frame, and hosts a trio of jaws: a lower jaw on a sliding subframe, and two upper jaws, each on an arm which is pivotally attached to the sliding subframe. Actuators, such as hydraulic cylinders, extend between the frame and one of the arms. As actuators extend, the subframe is carried toward a pipe joint. Upon contact between the pipe joint and the lower jaw, the arms pivot, causing the upper jaws to contact and grip the pipe joint. The wrenches of the wrench assembly may be adjustable relative to one another along a longitudinal axis of the pipe.Type: ApplicationFiled: February 14, 2024Publication date: August 15, 2024Inventor: Stephan Ulrich Berger
