Latest Patents

One of his latest patents is the "Zero tension web unwinder apparatus and method." This invention provides a method for the tensionless unwinding of a gossamer web of material from a bobbin. It utilizes a servo control system that connects the servomotors of a web handling apparatus to a bobbin unwinder. This system controls the unwinding speed of the bobbin unwinder in relation to the take-up speed of the web handling apparatus. A pulsed infrared sensor is employed to sense the web position, ensuring that the web remains in a substantially untensioned state. Additionally, a flow of air is directed onto the web to prevent unwanted movement caused by ambient air currents.

Another significant patent is the "Cigarette density profile measurement system." This system utilizes a hopper for storing numerous cigarette rods whose density is to be measured. It feeds one cigarette rod at a time to a fixed holder that incorporates a beta gauge system. This system sequentially irradiates a slice of the cigarette rod with beta particles to measure the mass of tobacco contained in that slice. A programmed microcomputer controls the system and analyzes the density data.
