Latest Patents

One of Allen's latest patents is titled "Method and apparatus for pre-spinning rotor forgings." This innovative method and system aim to relieve forging-induced residual stresses in rotor forgings. The process involves balancing a pre-spin machine with the forging mounted at a first rotational speed, followed by pre-spinning the forging at a substantially greater second rotational speed. The use of a one per rev sensor helps determine the weight placement angle, while a vibration sensor assesses the amount of weight to add to the spinning assembly. High-density non-metallic balance weights can be adhesively attached to the inside surface of the forging or spinning assembly. Additionally, the rotational inertia of the spinning assembly can be checked during a spin-up period by determining the rate of rotational acceleration versus the torque applied, allowing for the pre-spinning to be stopped if necessary.

Another significant patent by Allen is focused on "Methods and systems for balancing a rotatable member." This method includes separately balancing a first portion and a second portion of the rotatable member, which are mateable to each other. After coupling the two portions, a physical dimension is measured, and the balance weight magnitude and position are determined based on this measurement.
