Abstract: MAGNETIC PARALLEL-TO-SERIAL CONVERTER FOR   GAS TURBINE ENGINE PARAMETER SENSOR     ABSTRACT OF THE DISCLOSURE   A converter is provided for transforming the parallel output of a remotely located gas turbine engine parameter sensor into serial form for transmission to an engine control unit.          The converter is comprised of an interrogator which operates to sequentially interrogate a plurality of encoder magnetic cores which contain the sensed digital information.  The interrogator is comprised of a plurality of magnetic elements,each of which is connected to a corresponding individual encoder magnetic core.  The magnetic elements are normally maintained in a saturated state by two electrical current signals which are applied through appropriate biasing circuitry.  The current signals and biasing circuitry also act to sequentially unsaturate individual magnetic elements.         A high frequency excitation current is also applied to each of the magnetic elements.  As each magnetic element un-saturates, an interrogation current generated by the excitation current  is transmitted to a corresponding encoder magnetic core.  A single output conductor is connected with all of the magnetic cores for transmitting the serial information to the control unit.

Abstract: CLOSED LOOP SYSTEM            ABSTRACT      A closed loop system for the control of the air/fuel ratio of an internal combustion engine is disclosed.  The system includes an open loop air/fuel ratio controller that has a closed loop correction applied to its basic pulse width control signal.  The closed loop correction is based upon the bi-level switching of an oxygen sensor de-tecting a substantially stoichiometric condition in the exhaust gas of the internal combustion engine.  Performing the correction is an integral controller which responds to the switching of the exhaust gas sensor to increase the air/fuel ratio for one level of the sensor and to decrease the air/fuel ratio for the other level.  The limit cycle oscillation developed by the integral controller is modi-fied by increasing the authority and gain rate of the con-troller as a function of the distance the system is away from a reference point and responds to transient condi-tions rapidly and smoothly.  Another aspect of the inven-tion provides for the authority modification to take place when the controller reaches a threshold and to employ minimum  constant  authority  for  quiescent  conditions. Also, in response to a closed throttle or idle condition the quiescent authority level is reduced to a convenient idle level to prevent torque roll.

Abstract: ABSTRACT OF THE DISCLOSURE         A reversible rotary indexing mechanism capable of generating large indexing angles including those ex-ceeding one revolution.  A constant velocity rotary input is connected to a rotary output by an eccentric accelerat-ing-decelerating drive means which, by reason of a shift-ing mechanism, is selectively disengageable with the out-put at a maximum velocity, zero acceleration condition, while at the same time a constant velocity drive from the input is connected to the output.  Conversely, the con-stant velocity drive is disconnected at the same time that the accelerating-decelerating drive means is reconnected to accomplish deceleration.  An output lock is also pro-vided and actuators including composite cams can be uti-lized to accomplish the action of the shifting mechanism.     In addition, the mechanism can be used with higher harmonic components to increase the design flexibility with greater inherent dwell capabilities and significantly longer constant velocity ranges.

Abstract: ABSTRACT A propulsion unit for an electrically propelled track vehicle in-cludes two coaxial shafts, one connected to a propulsion motor and the other to a transmission.  The shafts are connected together by a coupling that in-cludes two coupling members, one on each shaft.  The coupling members are interlocked together to transmit operating torque between the motor and the transmission, and one of the coupling members includes a hub body on one of the shafts and a flange extending integrally from the hub body and interlock-ed with the other coupling member attached to the other shaft.  The housing supports the shafts in proper rotational position and is capable of with-standing a certain amount of operational stress, up to a known limit.  The first coupling member includes a weakened region between the hub and the flange to break in response to torque greater than that normally encountered but less than the limit stress required to break the housing, and a pre-ten-sioning spring presses the flange away from the hub toward the other coupling member so that, in the event of fracture, the hub and flange will be pushed apart and free to rotate relative to each other.
