Abstract: A method and apparatus for setting the positioning between a first rotating member and a second fixed or rotating member in a rotary machine comprises controlled thermal elements positioned on the frame supporting the members and/or on the rotating member(s) itself to counteract the effects of centrifugal force on the rotating member(s) to thereby approximately maintain the setting between the members. In one embodiment, the temperature of the frame controlled by the thermal elements may be maintained in proportion to the speed of rotation of the rotary member(s) to maintain the setting of the rotary machine throughout its operating speed range. In another embodiment, the initial setting between the first and second members may be precisely set by the controlled thermal elements at or near the setting representing the minimum useful loading, and due to the effect of centrifugal force be allowed to diminish to within the range of useful operating pressure or clearance.

Abstract: A mast step is mounted on a traveler having two parallel linear bearings which ride in lateral grooves on a central track. The central track has downward enlarged vertical holes on 2-inch centers which hold detent balls. The detent balls are locked in their upper active position with a contact and lock the traveler in a preselected position.

When the pedal is released, a spring tends to return the slider bar to misalign the receivers with the track openings. The detent balls are ramped upward out of the receivers into their upper operative position in contact with the downward opening locking recesses in the traveler.

Abstract: A method for controlling the quantity of fuel being supplied to an internal combustion engine having a power transmission means for transmitting engine torque to vehicle wheels. The fuel quantity is controlled to a required value after termination of a fuel cut operation which is effected at deceleration of the engine, by increasing a quantity of fuel set at least as a function of intake pipe pressure by an increment which is set in synchronism with generation of pulses of a predetermined control signal. The increase of the fuel quantity is effected for a period of time after a transition of the operative state of the engine from the fuel cut operation to a normal operation wherein fuel supply is effected has been detected and before a predetermined number of pulses of the above control signal generated are generated, so long as the power transmission means remains in a disengaged state. Preferably, the above increase of the fuel quantity is effected only when the engine speed is lower than predetermined rpm.
