Patent number: 5972417Abstract: An apparatus for use in electrostatically applying coating material to an object includes a nozzle which directs a flow of coating material toward the object. A power supply unit provides an electric field to electrostatically charge the coating material. Control circuitry is provided to monitor the operating efficiency of the power supply unit and to provide an output signal when there is an impending failure of the power supply unit. The control circuitry monitors the relationship between an input current to the power supply unit and an output current from the power supply unit. When the relationship between the input current to the power supply unit and the output current from the power supply unit is outside of a predetermined range, the control circuitry is effective to provide an output signal to notify an operator that there is an impending power supply unit failure.Type: GrantFiled: November 14, 1997Date of Patent: October 26, 1999Assignee: Nordson CorporationInventors: Jeffrey A.

Patent number: 5566042Abstract: An improved power supply for an electrostatic spray gun device having a voltage multiplier circuit adjusts to variations in the output load conditions of the multiplier circuit and dynamically modifies the operational loadline of the multiplier circuit in order to maintain optimal operating conditions for the spray gun device notwithstanding output load variations. The power supply utilizes a loadline manipulation circuit coupled to a feedback circuit that monitors the output load, and the manipulation circuit, in response to a feedback signal from the feedback circuit that is proportional to the output load, varies the input voltage level to the multiplier circuit to modify the loadline of the power supply in response to varying load conditions. The manipulator means of the power supply has memory means to store a variety of external commands which will control the manipulation means and a user interface to enter the external commands into the memory.Type: GrantFiled: June 2, 1995Date of Patent: October 15, 1996Assignee: Nordson CorporationInventors: Jeffrey A.
