Title: **David E. Gay: Innovator in AC Generator Technology**

Introduction

David E. Gay is a prominent inventor based in Noblesville, Indiana, known for his impactful contributions to the field of AC generator technology. With a total of 14 patents to his name, his work continues to push the boundaries of innovation within the industry.

Latest Patents

Among his most recent patents is the innovative method for manufacturing pole segments for a Lundell-type AC generator rotor. This method utilizes a mixture of ferromagnetic particles and a fugitive binder, allowing the rotor's teeth to be molded concurrently with its base from distinct particle mixtures. Following this, the segment undergoes a firing process to eliminate the binder and effectively sinter the metal particles together.

Another significant patent involves the creation of moldable ferromagnetic particles and the method of producing a magnetizable molding from them. This process entails spray-coating ferromagnetic particles with a slurry composed of insoluble thermoplastic particles suspended in a solution of a soluble polymer. This results in a coating mainly made up of insoluble thermoplastic particles embedded within a lesser amount of binder polymer, ultimately forming a robust matrix for the ferromagnetic particles upon compression molding.
