Title: The Innovations of David E. Rosenberg
Introduction
David E. Rosenberg is an accomplished inventor based in Pittsburgh, PA, known for his significant contributions to the field of brake shoe manufacturing. With a total of two patents to his name, Rosenberg has developed innovative methods that enhance the performance and reliability of brake shoe stock.
Latest Patents
Rosenberg's latest patents include a method of making brake shoe stock (II) and a method of making brake shoe stock. The first patent describes a process where pre-glued, coil-coated brake shoe stock is manufactured on a continuous coil coating line. A heavy gauge steel strip is continuously fed through abrasion and surface cleaning steps, optionally treated with a phosphoric acid/alcohol solution, followed by the application of a phenol-formaldehyde resin. This process includes a controlled curing step and results in coiled stock. The innovation improves the dimensional stability, thermal properties, and vibration and sound-dampening characteristics of the brake shoes. The second patent outlines a similar method, where the steel strip is spray treated with a phosphoric acid/alcohol solution and then sprayed with phenol-formaldehyde resin. Both methods result in brake shoes that exhibit higher shear strength and better adhesion to brake pad or lining materials compared to prior art, while also reducing manufacturing issues.
