  • Method for transferring power in a synchronous mode to a motor bus
    Patent number: 4310771
    Abstract: In a typical power system, a motor bus is fed by a main power system; and, an auxiliary system is provided to alternatively feed the motor bus. When a fast transfer from the main power to the auxiliary power system is desired, for example, in case of fault occurring in the main system, the inventive method transfers power in a synchronous mode; that is, power is transferred from the auxiliary system to the motor bus when the phase difference of the auxiliary system with respect to the frequency of the residual voltage on the motor bus is essentially zero degrees.

  • Piezoelectric igniter apparatus for gas grill
    Patent number: 4302181
    Abstract: The piezoelectric generator and the spark electrodes are assembled as an integral unit, the electrodes being at the upper end of the unit and projecting upwardly while the actuating button of the current generator projects downwardly from the lower end of the unit. The unit is movable vertically. When upward pressure is exerted on the button the unit moves to an upper position at which the electrodes are adjacent the gas burner and upon reaching that position continued upward pressure on the button actuates the current generator. When the button is released the unit descends by gravity to a lower position at which the electrodes are spaced away from the flame of the burning gas.
