Title: The Innovations of John Michael Rees

Introduction

John Michael Rees is a notable inventor based in London, GB. He has made significant contributions to the field of electric lamps, holding a total of four patents. His work focuses on enhancing the efficiency and longevity of incandescent lamps through innovative techniques.

Latest Patents

One of his latest patents is for an incandescent halogen lamp with a protective envelope coating. This invention relates to electric incandescent lamps that contain a gas fill with halogen. The internal surface of the lamp envelope, as well as the exposed surface of internal components, is protected from halogen attack by a continuous imperforate coating made of a metal oxide resistant to such attacks. The oxide is formed in situ from a compound of the metal deposited as a solution on the surface. The preferred oxide is alumina, although other oxides of polyvalent and transition metals may also be used. This protective coating prolongs the life of the lamps and allows for the use of more resistant and potentially cheaper materials for certain lamp components.

Another significant patent by Rees is a method of introducing fluorine into a lamp. This invention pertains to the manufacture of electric lamps that contain fluorine in their gas fill. Fluorine can be accurately introduced into an electric lamp envelope in the form of a fluorocarbon polymer. By dissolving a soluble fluorocarbon polymer, such as degraded PTFE, in a suitable solvent, the resulting solution can be metered accurately into the lamp envelope, with the solvent subsequently evaporated. This method addresses the challenges of dispensing precise quantities of an extremely reactive gaseous material.
