Latest Patents

One of his latest patents is for "Glass-encapsulated abrasive particles for vitreous bond grinding wheels." This invention involves the creation of substantially spherical glass globules that encapsulate abrasive particles. These globules are designed for incorporation into vitreous bonded grinding wheels and are produced through a series of steps that include forming a mixture of glass powder, abrasive particles, and a fluent binder. The binder is fused to create a solid mass, which is then attrited into discrete particles. The desired size fraction is separated and heated to fuse the glass particles into globules that encapsulate the abrasive particles.

Another significant patent is for "Refractory metal oxide coated abrasives and grinding wheels made." This invention provides abrasive particles with a refractory metal oxide coating, a non-metallic precursor, or an elemental metal coating of at least about 20 weight percent. It also includes abrasive tools such as grinding wheels, particularly vitreous bonded grinding wheels, that utilize these coated abrasive particles.
