Title: Innovations of Inventor Peter Brownell

Introduction

Peter Brownell is a notable inventor based in Providence, RI (US), recognized for his contributions to the field of composite materials and filtration technologies. With a total of seven patents to his name, Brownell has made significant advancements that enhance safety and efficiency in various applications.

Latest Patents

One of Brownell's latest patents is for a composite sandwich element. This innovative element features at least one wall made from a phenolic resin binder and a layer of cellular polymeric foam or felt of imide polymeric material. In the event of a fire, this composite sandwich element demonstrates levels of heat release, flammability, smoke release, and toxic gas release that are below predetermined levels, making it suitable for use within the passenger compartment of commercial aircraft. In preferred embodiments, the design includes two walls with the cellular polymeric material positioned between them. The wall is enhanced with glass fibers in web form, while the polymeric resin binder acts as an adhesive or reinforcing binder. Additionally, a barrier film, either metallic or polymeric, may be incorporated to ensure the composite sandwich element is impermeable to air.

Another significant patent by Brownell is a method of applying a wettant to a filtering media. This method involves atomizing the wettant into small particles, which are then entrained in a carrier air stream. The carrier air stream is forced through the filter media at a face velocity that is substantially greater than what the media experiences during actual use. This technique ensures thorough dispersal of the wettant throughout the filter media, thereby reducing or eliminating the migration of particles into the effluent air stream during filtering.
