Title: The Innovations of Jack A. Tiethof
Introduction
Jack A. Tiethof is an accomplished inventor based in South Plainfield, NJ (US). He has made significant contributions to the field of materials science, particularly through his innovative patents. With a total of 3 patents, Tiethof has demonstrated a commitment to advancing technology and improving industrial processes.
Latest Patents
Tiethof's latest patents include a novel sorptive clay composition and method of manufacture. This innovative product is created by treating attapulgite clay with sodium silicate and heating it to expel moisture, resulting in a product that contains about 7-20% total volatile matter. The addition of acid allows for the pH of the aqueous slurry to be maintained in the range of 5 to 10. This sorptive clay product exhibits impressive water and oil absorption properties, along with resistance to wet breakdown, comparable to higher-temperature activated attapulgite products. Another notable patent is the hydrosulfite preparation process, where aluminum metal is activated with hydrochloric acid and then reacted with an aqueous solution of sulfur dioxide. This process produces an aluminum hydrosulfite (dithionite) liquor that is useful for bleaching materials such as clay. The aluminum hydrosulfite can be converted to a sodium hydrosulfite liquor by precipitating aluminum with a sodium base.
