Introduction

John S. Jackson is a notable inventor based in West Allis, WI (US). He has made significant contributions to the field of electrical engineering, particularly in the development of advanced resistor technologies and electromagnetic contactors. With a total of 2 patents, his work reflects a commitment to innovation and practical solutions in electrical systems.

Latest Patents

One of Jackson's latest patents is a resistor adapted for use in forced ventilation dynamic braking. This invention features a continuous ribbon resistor element with multiple conjunctive lengths that are alternately connected by reflexes. The design is supported in a frame made of silicon-bonded laminated mica. The ribbon elements are uniquely formed with a flat convolution center offset to one side, while lateral portions are offset to the opposite side. This innovative structure allows for efficient thermal management, as thermally conductive termination connections are brought outside the frame to dissipate heat effectively.

Another significant patent by Jackson is for a D.C. electromagnetic contactor. This device includes molded insulating shell halves that secure a blowout coil and stationary and movable contacts, effectively trapping an armature assembly. The design incorporates windows in the shell halves to ventilate the electromagnet coil during operation, allowing for easy removal of the electromagnet without disassembling the contactor. Additionally, the arc chute design enhances the performance by splitting the arc into four series segments, significantly increasing the overall length of the arc compared to similar prior art devices.
