Latest Patents
McCoy's latest patents include a power phase regulator circuit improvement for motor start switches. This invention features a fuel oil burner that utilizes a hot surface ignition with an ignitor that is fully sintered and has essentially no porosity. The voltage phase regulator circuit applies rectified half-wave AC line voltage, full-wave rectified AC, or either half-wave or full-wave rectified AC line voltage to the ignitor. This setup supplies power to the ignitor and the blower motor. Additionally, it includes an AC-to-DC converter, a DC voltage preregulator, and a DC voltage regulator that provides twelve volts DC for the operation of a control circuit. This control circuit has a first time constant circuit for preheating the ignitor and maintaining it at a consistent ignition temperature for a predetermined ignition trial time period. Furthermore, a second time constant circuit drives the second and third motor drive circuits. The third motor drive circuit energizes the start winding of the blower motor, while the second motor drive circuit energizes the main winding of the blower motor, thus starting the motor and providing fuel to the combustion chamber during the ignition trial period. A third time constant circuit either maintains the fan blower motor in its energized state if a flame of sufficient magnitude and frequency is detected or de-energizes the blower motor if the flame is not detected within one second after the ignitor is de-energized. A lock-up circuit ensures that if no flame is detected, restart is accomplished only by first removing power and then reapplying power to the unit. This unit can be restarted even if there is a flame in the combustion chamber. Additionally, a shutdown circuit is provided if the flame detector shorts during burner operation.
