  • Method and apparatus for controlling a bowling ball lift mechanism
    Patent number: 4770417
    Abstract: Method and apparatus for controlling and operating the return ball lift mechanism in a bowling alley. In a preferred embodiment the motor which drives the lifting belt is normally inoperative and it is actuated when a ball arrives to be lifted into the storage rack. A photo detector is utilized to detect the presence of the returning ball and provision is made to actuate the motor for a total of four seconds. In the event a second ball arrives before the end of four seconds, timing begins all over again. A feature of the invention is the elimination of a centrifugally operated switch to control the START winding of the motor as a solid state timer controls the operation of both windings of the motor.

  • Filament bypass circuit
    Patent number: 4727449
    Abstract: A filament bypass circuit for use with a string of lamps in series capable of continuing current flow when a lamp in the string fails. Each lamp is provided with a shunt circuit consisting of a series circuit of a diode and a silicon bilateral voltage triggered switch. The switch becomes conductive upon the application of a substantial increase in voltage from the A.C. source and remains conductive until there is an interruption of current flow or current flow drops below its required holding value. The diode insures that during continued operation after a failure there will not be an excessive voltage applied to the remaining lamps, and also serves as an indicator of a failed lamp.
