Latest Patents

Among his latest patents is a control system for a glass bending platen. This invention features a closed-loop control system for a hydraulically actuated glass sheet press bending platen. The flow of fluid supplied to the cylinder operating the press platen is controlled through a servo solenoid valve. A linear motion transducer associated with the platen sends appropriate signals to a programmable motion controller. The motion controller manages a position module that is operatively coupled to a servo solenoid valve, regulating the flow of hydraulic fluid from a pump to the cylinder. The motion controller utilizes data from the linear motion transducer to make necessary corrections, ensuring that the platen cycles precisely according to a predetermined program. In a second embodiment, this closed-loop control system is combined with precision control of a variable speed glass sheet conveyor, improving the registry of the glass sheet being bent with the platen member.

Another significant patent is an apparatus for processing glass sheets. This apparatus includes a furnace and a bending station traversed by a conveyor for carrying the glass sheets. A plurality of heaters mounted in the furnace heats associated areas of the glass sheets according to setpoint temperature signals representing desired values for heating. Parameters such as thickness and color of the glass sheets are sensed, allowing for adjustments to the setpoint signal values. These parameters also influence the spacing between the upper and lower mold members in the bending station, adjusting the bending pressure applied to the glass sheets. Furthermore, the parameters are utilized to change the speed of the conveyor sections, varying the time the glass sheets spend in the furnace and thus the amount of heat imparted.
