Latest Patents

Lemme's latest patents focus on an improved catalytic converter designed for the exhaust gases of automotive engines. The first patent describes a catalytic converter that includes a plurality of honeycomb-type catalyst carrier elements, annular spacer members, and cushioning rings. These components are mounted in a compressed sandwich fashion within a cylindrical casing section. The design ensures that the only rigid connection is between the ends of the assembled sandwich and the casing. The cushioning rings, formed of compressed metallic wires, have a triangular cross-sectional configuration that engages within correspondingly shaped annular spaces at the ends of the carrier elements. This innovative design allows for effective compressive forces to be transmitted to the associated carrier elements.

The second patent also pertains to an improved catalytic converter and gas purification method. It emphasizes the importance of the length of the catalyst carrier elements, ensuring that gases flowing through the passages contact the catalyst effectively before transitioning from a turbulent to a laminar flow condition. This design enhances the efficiency of the catalytic converter, making it a significant advancement in automotive technology.
