Abstract: A method is provided for assembling a load bar assembly. The method includes providing a first linear stage having a first alignment mechanism that is configured to move the load bar assembly in a first direction. A second linear stage is provided that includes a second alignment mechanism that is configured to move the load bar in a second direction that is different from the first direction. The first alignment mechanism is positioned with respect to the second alignment mechanism such that the first alignment mechanism and the second alignment mechanism are prevented from being back-driven. The first alignment mechanism and the second alignment mechanism are configured to lock if one of the first alignment mechanism and the second alignment mechanism fails.

Abstract: A starting control circuit is provided for an alternating current motor having a run winding and a start winding and a mechanical rotational output. The motor is powered by an alternating current source. A reference oscillator produces pulses having a reference frequency. A first control circuit is provided for counting the number of reference pulses produced during a predetermined number of cycles of the alternating current source. A sensor is provided for sensing a predetermined amount of rotational movement of the mechanical rotational output of the motor and producing a sensor pulse indicative thereof. A second control circuit is provided for counting the number of reference pulses produced during the time between a predetermined number of sensor pulses and for comparing the counts on the first and second control circuits. The second control circuit assumes first and second output states dependent on the relationship between the first and second output counts.
