Latest Patents

One of his latest patents is titled "Method for sizing and installing tubing in manifolds." This invention provides an apparatus that sizes tubing and positions and installs a manifold for single or multi-pass heat exchangers. The apparatus allows for the tubing to have at least one first end and one second end, with the first end sized to a desired perimeter dimension while simultaneously positioning and installing a manifold with an opening for receiving the first end. The second end is also sized to a second desired perimeter dimension, with a second manifold positioned for the second end. A positioning control aids in the insertion of the ends into the manifolds to the desired depth or pressure. This invention is capable of accommodating variously dimensioned tubing.

Another significant patent is the "Vacuum braze cycle for clad aluminum sheet." This patent describes an improved heating cycle for brazing an assembly of clad aluminum sheet components. The process involves a dwell at a temperature slightly above the eutectic melting point, which effectively partially melts the cladding. This dwell helps vaporize residual magnesium from the clad alloy, enhancing the disruption of the oxide film on the cladding surface. This innovation ensures a more uniform flow of braze alloy into seams, resulting in strong, leak-free joints in the brazed structure.
