Abstract: A control system for use with a master engine and one or more slave engines. The master engine produces a master torque and the slave engines produce slave torques. The master engine and the slave engines have computers that control fueling to the engines. The control system of the invention includes an interface between the control computer for the master engine and the control computers for the slave engines. The master control computer controls the slave control computers through the interface, such that the slave torques are a function of the master torque.

Abstract: A retractable hitch is adapted to be mounted to a vehicle, such as in the bed of a pickup truck. The hitch includes a ball piece for releasable engagement with a coupling mechanism secured to a trailer as known in the art. The hitch has a frame secured to the vehicle, and the frame provides a substantially flat upper surface with a sleeve opening extending below the upper surface. The ball piece moves in the sleeve between an operative position, wherein it extends above the upper surface, and a retracted position wherein the ball piece is positioned below the upper surface. A raising/lowering control moves the ball piece within the sleeve. The raising/lowering control is mechanically coupled to the ball piece with a raising/lowering control linkage, which accesses the ball piece through a bottom and a vertically extending slot in the sleeve. The raising/lowering control linkage contacts a bottom bearing surface of the ball piece to raise the ball piece upward. A spring assists in raising the ball piece upward. A locking control having a horseshoe shaped locking pin is used for selectively locking the ball piece in the operative position or in the retracted position. Operation of the raising/lowering control linkage involves only translational movement which can be quickly accomplished from the wheel well of the vehicle.

Abstract: A trailer hitch uses a draw bar to interconnect tractor and trailer vehicles. The draw bar includes an elongated shank with a transverse throughway. A resilient cushion is disposed in the throughway. A passageway is associated with the throughway to receive a hitch pin such that longitudinal motion of the shank is resiliently resisted by the cushion. The cushion may be disposed in a rigid casing to form a cartridge that inserts into the throughway, and the passageway may be provided by a reciprocating slide member in the casing. Cushions may be employed in the casing to resist motion during both braking and acceleration. Cartridges having differing performance may be interchanged in the system. A method employing such structures is described.
