Introduction

Ralph W. Bruce is a notable inventor based in Arnold, MD (US), recognized for his contributions to advanced materials and joining techniques. He holds a total of 4 patents, showcasing his innovative approach to solving complex engineering challenges.

Latest Patents

One of his latest patents is titled "Microwave Assisted Reactive Brazing of Ceramic Materials." This invention presents a method for joining similar materials to create multi-component assemblies, ensuring that the joint materials share comparable physical, chemical, and electrical characteristics with the base materials. The process involves aligning the materials, applying a joining material, and focusing a microwave beam on the joint area to initially heat it. This allows the joining material to soften and fill physical discontinuities while keeping the surrounding surfaces cool. The method then rapidly heats the joint area to the reactive temperature of the joining material, followed by rapid cooling and maintaining the joint area at a recrystallization temperature. The materials used can include ceramics such as aluminum oxide.

Another significant patent is "Microwave Assisted Continuous Synthesis of Nanocrystalline Powders and Coatings Using the Polyol Process." This method involves forming a nanocrystalline metal by providing a reaction mixture that includes a metal precursor and an alcohol solvent. The mixture is continuously flowed through a reactor while applying microwave or millimeter-wave energy localized to the vicinity of the reaction mixture. The heating process allows the alcohol solvent to reduce the metal precursor to a metal within the reactor.
