Title: Innovations of Frederick D Weaver
Introduction
Frederick D Weaver is a notable inventor based in Chillicothe, OH (US). He has made significant contributions to the field of microencapsulation and pressure-sensitive record materials. With a total of three patents to his name, Weaver's work showcases his innovative spirit and technical expertise.
Latest Patents
One of Weaver's latest patents is an encapsulation process that involves the manufacture of microcapsules. This process includes preparing hydrophobic and hydrophilic phase components, where the hydrophobic phase consists of a homogeneous solution of an electron donating chromogenic material and a hydrophobic material. The hydrophilic phase is a mixture of a regulating agent, specifically a starch material, and water. The combination of these phases forms an oil-in-water emulsion, which is further treated to create discrete microcapsules that are substantially impermeable to the hydrophobic emulsion component.
Another significant patent by Weaver is related to pressure-sensitive record material. This invention comprises a paper sheet material coated with droplets of liquid, which includes 2,2,4-trimethyl-1,3-pentanediol diisobutyrate. The liquid interacts with at least two color-producing reactants, one of which is a chromogenic dye-precursor. This innovative approach allows for the development of color when the reactants come into contact.
