Abstract: An electronic transmission controller for determining the shift points of a powered vehicle with a plurality of forward and reverse gears and a neutral gear shift position wherein a throttle setting signal, a vehicle speed signal and a gear range select signal are monitored and processed to produce optimum shift points, gear change commands, forward-reverse shift commands and a throttle inhibit signal to facilitate downshifting of the transmission. With the exception of the throttle transducer, the monitoring and processing means are primarily digital.

Abstract: An electronic governor for controlling the speed of one of two coupled prime movers wherein signals corresponding to wheel speeds of each of the two prime movers are compared to produce an error signal for controlling an actuator on one prime mover. The speed of the controlled prime mover may be abruptly reduced where the error signal exceeds a pre-determined threshold value. Monitoring means generally comprise digital circuitry, while control of the actuator is primarily analog acting through a servo loop containing a throttle position sensing device on the master prime mover, the error signal generating device and a throttle control device for the controlled prime mover.

Abstract: Means for automatically positioning light sensing means relative to a linear series of light sensitive areas, e.g., apertures, on a longitudinally moving conveyor belt which is monitored by the sensing means. Rollers are used to receive the side edges of the belt, such rollers being freely rotatable so as to reduce the tendency of the belt edges to fray or otherwise degrade. The light sensing means and rollers are both mounted on a suspended frame means which moves transversely in response to transverse movements of the belt, whereby the sensing means is always aligned with the linear series of light sensitive areas on the belt.

Abstract: The cotton module builder comprises a mobile, open-bottomed rectangular frame structure into which field cotton can be deposited. A compacting mechanism is mounted at the open top of the frame structure in order to compress the cotton therein into a compact, self-supporting stack (or module) which can be left in the field when the module builder is moved to a new location. The stack can then be picked up later and transported to a cotton gin.An improved side frame structure for the module builder increases the structural rigidity thereof and includes a continuous side wall beam of triangular cross sectional configuration interconnecting the side wall struts. This beam provides high torsional resistance and minimizes the horizontal deflections at the base of the vehicle, especially when the rear door of the module builder is open as when the stack or module of cotton is being deposited in the field.
