Latest Patents

One of his latest inventions is the Offset Ink Jet Postage Printing system. This innovative postage meter utilizes an offset printing roll, where a die plate carries fixed information such as the city and state, along with variable information like the date and postage amount. At the beginning of a revolution of the printing roll, the second region is depressed, allowing an inking roll to apply ink to the first region. Subsequently, the second region is moved into the plane of the first region, and an ink jet printing device projects ink droplets onto the second region to form the variable information. The quality of the printed form is then sensed, and if acceptable, a document is printed. If not, both regions are wiped clean, and the operation is repeated. The cleaning process can utilize a hydrophilic oil applied to the printing roll. Additionally, apparatus can be employed to enhance the characteristics of the ink before it reaches the document.

Another significant patent is for Vinyl-Hydro Polysiloxane Copolymers. This invention involves novel radiation-curable, liquid vinyl-hydro copolymers and coating compositions that are free of volatile solvents. These compositions can be rapidly applied to a substrate and cured by radiation exposure, forming release coatings with excellent properties regarding adhesives.
