  • Bio-based binder system
    Patent number: 10369623
    Abstract: A bio-based binder system for use in preparing foundry molds. In a preferred embodiment, the system includes the use of a) a polyermizable hydroxyl-containing component comprising a saccharide, b) an isocyanate component, and c) a catalyst, and preferably amine catalyst, component adapted to catalyze the polymerization of a) and b), in the presence of a foundry aggregate such as sand. The system can be used in any suitable manner, including in either a cold box process or no bake process as described herein.

  • Diamond tool blade with circular cutting edge
    Patent number: 7524237
    Abstract: An apparatus for turning a hard and/or brittle material includes a precision workpiece spindle, a workpiece support, a hard and/or brittle workpiece rigidly coupled to the workpiece support, and a diamond tool blade rigidly coupled to a spin-turner mechanism. The diamond tool blade is formed to include a cutting edge arranged to confront the hard and/or brittle workpiece to remove material from the workpiece to form precision-turned components such as optical lenses, mirrors, and optical molds.
