Latest Patents
Calhoun's latest patents include an "Apparatus for measuring and controlling a force" and a "Method of and apparatus for making up a threaded connection." The first patent describes an innovative apparatus designed to measure and control forces such as torque, pull, or weight. This device is particularly useful for ensuring that a specified torque is applied when making up two members with mating threaded connections, such as pipe joints and head bolts. The apparatus features a comparator that compares the measured torque with a desired value, disengaging the joint-making process if the measured torque exceeds the selected limit. Additionally, it includes a testing circuit for operational verification and an adjustment circuit to align the output with known test values.
The second patent focuses on a method and apparatus for making up threaded connections. This invention ensures that a specific number of threads are engaged and that the correct torque is applied. During the process, measurements of torque and turns are taken to prevent the formation of faulty joints. The system is designed to avoid erroneous measurements that may arise from bending or swaying of the members during the makeup process.
