Title: Joseph Redmond Farnand: Innovator in Coal Processing and Hollow Article Formation

Introduction

Joseph Redmond Farnand is a notable inventor based in Ottawa, Canada. He has made significant contributions to the fields of coal processing and the creation of hollow articles. With a total of two patents to his name, Farnand's work showcases innovative approaches to complex engineering challenges.

Latest Patents

Farnand's latest patents include a process for solids recovery from coal liquefaction slurry. This process involves removing mineral matter from a solubilized coal slurry while retaining asphaltenes with the coal solution. The slurry is agitated with an alkanolamine or other hydrophilic agglomerating agents in the presence of an aromatic solvent or polyvinyl alcohol. This method forms relatively large agglomerates that contain mineral matter, undissolved coal, and the agglomerating agent, which can be separated rapidly from the coal solution by gravity settling. The agglomerates can then be washed with a solvent to recover the entrained coal solution, which can subsequently be distilled for recycling purposes.

Another significant patent by Farnand is the formation of hollow spherical articles. This invention focuses on preparing hollow articles, such as microballoons and hollow fibers, by dispersing or dissolving a soluble film-forming solid in a core solvent that is normally solid but can transform slowly to gas. The blend is shaped while molten, cooled to solidify, and the solid core material is slowly removed as a gas. This process allows the film-forming solid to migrate and form a shell with a non-uniform cross-section, resulting in a unique outer skin and inner sponge lining.
