Title: Innovations by James W. Alford
Introduction
James W. Alford is a notable inventor based in Pittsburgh, PA, who has made significant contributions to the field of engineering. He holds 2 patents that showcase his expertise in developing advanced testing apparatuses for electrical components.
Latest Patents
Alford's latest patents include an "Apparatus and method for impact testing for electric generator stator" and a "Rotor bore inspection system." The first patent focuses on a method and apparatus for performing remote impact testing for generator stator wedges and ripple springs. It utilizes an improved low profile carriage to correlate wedge displacement data with the force required to displace the wedge. A calibrated test stand, equipped with a hydraulic load cell, generates calibration curve sets that allow for the analysis of force and displacement data during actual stator testing. The preferred embodiment employs a capacitive sensor to measure the displacement or vibration of stator wedges when impacted by a hammer with a known force.
The second patent, the "Rotor bore inspection system," is designed for examining elongated cylindrical bodies with axial bores, such as rotor shafts. This apparatus includes an energy transducer supported by a drive rod, which is advanced within the bore to obtain readings indicative of the physical condition of the body. The drive unit, which supports the rod, is centered within the bore by a fixture that allows for axial alignment adjustments. The system is powered by DC permanent magnet motors, with precise control achieved through position and velocity error signals derived from a pulse encoder.
