摘要： A single phase, two pole A.C. split-phase unidirectional induction motor uses a current sensing relay and connects a main winding with a single phase A.C. electrical power source while a pair of associated relay-contacts operably connect a starting winding to the power source with the contacts closing in response to a sensed first predetermined main winding current and opening in response to a second lesser predetermined main winding current. Each of the starting winding poles are spaced from each of the main winding poles by less than ninety physical degrees in the direction of rotor rotation in order to provide the first predetermined main winding current at a first predetermined rotor speed and the second predetermined main winding current at a second predetermined speed and torque to maintain the heating of the starting winding within a predetermined temperature while the pair of relay contacts remain in the closed condition.

摘要： A water heating system includes a burner and a gas valve fluidly connected to the burner to deliver a flow of combustible gas thereto. The gas valve has an adjustable throttle for the flow of combustible gas, along with a motor to adjust a position of the throttle. A controller is configured to determine a throttle position corresponding to a target air-fuel ratio of the burner during a calibration sequence, and to control the motor in order to operate the burner at that target air-fuel ratio throttle position during a start sequence. The controller is configured to monitor a characteristic of the burner during the start sequence, and to initiate the calibration sequence if the monitored characteristic exceeds an error threshold.

摘要： A drain valve and method for assembling a drain valve. A valve assembly is inserted into a pipe, and a reduced diameter portion is formed in the pipe to create a substantially water-tight seal between a portion of the valve assembly and the pipe. A second reduced diameter portion may be formed in the pipe to provide a thrust bearing surface for resisting sliding movement of the valve assembly within the pipe. A transverse hole is provided in the pipe to provide access to a rotatable mechanism in the valve assembly to permit and restrict fluid flow through the drain valve.
