Title: Innovations by Richard R Dahlen

Introduction

Richard R Dahlen is an accomplished inventor based in White Bear Lake, MN (US). He holds 3 patents that showcase his contributions to energy control and thermal insulation technologies. His work reflects a commitment to enhancing energy efficiency and improving material properties.

Latest Patents

One of Dahlen's latest patents is for an energy control sheet having insulative properties. This composite energy control sheet features a transparent-reflective metal layer coated on a self-supporting transparent polymeric foil, which is then protectively covered with a transparent polymeric layer. The protective layer is designed to transmit 80% or more of the normal room temperature radiant energy spectrum, significantly reducing heat loss from a room when positioned adjacent to a glazing unit. This innovation greatly improves the cold weather performance of the sheet. Suitable polymers for the polymeric layer include polyethylene, polypropylene, and polyacrylonitrile.

Another notable patent is for a process for providing insulating covers. This process involves forming a plurality of hollow interior, discrete ceramic particles and firing them at a temperature of at least 350 degrees Celsius. The heated liquid is then covered with at least a 1/8 inch thick layer of the fired particles. This patent also describes a potentially improved ceramic thermal insulating particle that contains a hollow interior with multiple partitions.
