Abstract: ABSTRACT OF THE DISCLOSURE        A Conductor roll used for masking one face of a metal strip while the other face is being electro-treating comprises an elastomeric-covered cylinder having a metallic contact ring in the center thereof for electrical contact with the strip being treated.  To minimize high transfer current densities, each edge of the contact ring has a cantilevered flange overlying a portion of the elastomer.  It has been found, due to differential thermal expansion at operating temperature of both the elastomer and the metal contact ring, that the cantilevered flange section of the contact ring is forced up to an excessive extent, resulting in high bending stresses generated in the strip at the region of the contact ring-elastomer interface.  By providing a taper on the cantilever flange section to compensate for the difference in thermal expansion, bending stresses in the strip are reduced to insignificant values, whereby eliminating creases and scratches in the strip.

Abstract: DUAL TURBINE CONTROLLER           ABSTRACT OF THE DISCLOSURE     Primary and secondary controllers both receive independent digital representations of shaft speed.         Only one of the outputs of the two controllers is used.         In order to detect a fault and isolate it to one of the two controllers, comparison is performed on the response of each controller with the response of the other controller.  In addition, the response of each controller is compared with a system mathematical model which predicts the response which each controller should provide to a given set of inputs.  If the first comparison indicates that one of the controllers is bad, the comparison with the system mathematical model identifies the faulty controller and provides a signal which removes it from operation and enables the good controller to begin providing control signals.

Abstract: IMPROVED DIFFERENTIAL CLUTCH PULSING SYSTEM          ABSTRACT OF THE DISCLOSURE          A standby control unit is described for use in a drive system having two synchronous motors driving a common load through air operated clutches where the load is balanced or divided between the two motors by differentially pulsing the clutches.  A control unit is responsive to the measured load on each motor and provides pulses which momentarily reduce the voltage to electrically controlled valves which control the air supply to respective clutches. By making slightly longer the pulse for the control of the clutch in the motor drive having the greater load, the load unbalance is reduced.  In the event of a failure in the control unit, the standby control is automatically connected to the electrically controlled valves.  It has a voltage source which provides a voltage to each valve to keep the respective clutch in a non-slipping state.  The standby control includes a capacitor for each valve. The capacitors for each valve can be simultaneously switched into the circuit, momentarily reducing the voltage to the respective valve as the capacitor begins to charge thus permitting the clutch to slip.  As the capacitor charges, the voltage at the valve returns to normal and the clutch to its non-slipping state.  An adjustable resistance in the charging circuit for the capacitor can provide a differential in the pulse of reduced voltage to each valve by making the charging rate slightly different.

Abstract: SEED PLANTER     ABSTRACT OF THE DISCLOSURE The present invention is an improved seed sower unit and an improved seed supply hopper for the head. Opposed vacuum disc-type sower units are mounted in a frame. A seed hopper is mounted on a separate subframe. The hopper subframe has mounting notches which rest on stub pins projecting from the main frame. A latch mechanism holds the seed hopper subframe in place during operation. By opening the latch, the subframe with the seed hopper can be lifted vertically from between the sower discs to permit ready access for cleaning or repair. The seed hopper portion has a sloping bottom member adapted to fit between the sower discs to form a seed trough. This sloping member has a gate so that seed can be easily drained from the system into a container without loss. An optional second gate enables the seed hopper to be isolated from the seed trough. By making the seed hopper vertically removable, the sower units may be located in close proximity to each other, thus enabling similarly close crop row spacing.
