Title: Edward M. Petrie: Innovator in Electrical Engineering
Introduction
Edward M. Petrie is a notable inventor based in Wilkinsburg, PA (US). He has made significant contributions to the field of electrical engineering, holding a total of 4 patents. His work primarily focuses on improving the efficiency and functionality of electrical apparatuses.
Latest Patents
One of his latest patents is for a transformer oil pump bearing material. This innovation features a fluid-cooled electrical apparatus characterized by a new and improved pump for circulating fluid within the apparatus. The pump includes a motor portion in fluid communication with a pump portion, supported by non-electrically conductive bearings made from a polyamideimide thermoplastic resin. Another significant patent is for a technique for fabricating radiation-sensitive dosimeters. In this process, finely-divided particles of a selected phosphor material are combined with an aqueous solution of a suitable binder material to form an emulsion. This emulsion is spread uniformly on a smooth surface of a support member, heated to remove water, and sintered to produce a strong, continuous film. The film can then be peeled from the support member, resulting in a uniformly thick sheet of phosphor and binder from which dosimeters can be cut or stamped to any desired size.
