Latest Patents

Brophy's latest patents include a development apparatus for a liquid electrographic imaging system. This innovative apparatus is designed to develop a latent electrostatic image on an imaging substrate. It features a cleaning roller that effectively removes back-plated developer from a development device, along with a squeegee apparatus that eliminates both 'drip-line' and 'wrap-around' developer liquids from the imaging substrate. The squeegee roller is equipped with a crowned profile and a loading mechanism that ensures a uniform loading force across the pressure nip formed between the squeegee roller and the imaging substrate. Additionally, the cleaning roller incorporates fiber cleaning media and fluid delivery means to flush back-plated developer from the cleaning media.

Another patent focuses on an apparatus and method for removing excess developer liquid from an imaging substrate. This system utilizes a squeegee roller and a loading mechanism to effectively remove excess developer liquid. The design allows for a portion of the excess liquid to pass to the downstream side of the squeegee roller, where it can be transferred back to the imaging substrate. A second developer liquid removal mechanism is also included, featuring a second squeegee roller that operates adjacent to the first, ensuring thorough removal of excess developer liquid.
