Latest Patents
One of Jean C. Graffin's key inventions is an optical projection system equipped with a plate positioner. This system is designed to position a sensitized plate in the image plane of a projection lens. It features a set of extensible jacks arranged in a circle around the lens. The desired image plane is defined by the ends of the jacks when they are in the outwardly displaced position. The plate can be placed against the ends of the jacks using a spherical-bearing unit that is locked in position. Once secured, the jacks withdraw, allowing the plate to be displaced in the image plane while maintaining the focusing distance. This invention is particularly well-suited for the construction of photorepeaters. Jean C. Graffin holds 1 patent for this innovative technology.
