  • Automatic fuel control and engine synchronizer system and apparatus
    Patent number: 4926628
    Abstract: A first computer and a first servo with connecting apparatus are used to drive a first engine throttle. A second servo and a second computer together with second connecting means are used to drive a second engine throttle. In addition, a cross connection capstan, cable, pulley and electrically clutched capstan are used to selectively connect the two engine throttles, thereby allowing for the operation and regulation of both engine throttles by either the first servo/computer combination or the second servo/computer combination.
