Title: John B Gilmour: Innovator in Perlite Applications
Introduction
John B Gilmour is a notable inventor based in Whittier, CA (US). He has made significant contributions to the field of materials science, particularly in the utilization of expanded perlite. With a total of 2 patents, Gilmour's work focuses on innovative processes and products that enhance the properties of perlite in various applications.
Latest Patents
Gilmour's latest patents include a process for agglomerating expanded perlite fines. This process involves mixing expanded lightly milled perlite fines with aqueous alkali metal silicates. The wet mixture is then dried at temperatures ranging from 600°F to 1400°F in a moving air stream to form agglomerates that serve as effective filter aids. Additionally, these agglomerates can be heat treated in an indirect fired rotary kiln to further reduce water solubility, and they can be separated into size factions either before or after heat treatment. Another significant patent is for a mineral aggregate acoustical board. This invention features monolithic acoustical panels that include relatively coarse particles of expanded volcanic glass, such as perlite, and mineral fiber. The resulting panel possesses a highly porous structure that provides excellent noise suppression characteristics.
