Abstract: A starting control circuit is provided for use with a mechanical duty single phase alternating current motor having a start winding and a main or run winding. Both the main and start windings are electrically connected to the alternating current source during the initial starting of the motor. Transducers detect the current phase of both the start and main winding and comparators then compare these current phases together. A comparator generates a pulsed output signal when the phase of the start winding lags the phase of the main winding and this pulsed output signal has a pulse width proportional to the magnitude of the phase lag between the start and main windings. These pulsed output signals are integrated and a electronic switch is activated to disconnect the start winding from the power source whenever the integrated pulsed output signals exceed a predetermined value.

Abstract: An adjustable protecting guard apparatus for a table saw having a guard positionable over the saw blade. The adjustable protection guard apparatus has a telescoping arm extending from one end of the saw table which supports a guard superstructure. A hinged connection on an edge of the guard superstructure permits the guard superstructure and the attached guard to pivot up and away from the saw blade. A control module simultaneously deactivates the motor rotating the saw blade with the pivoting of the guard superstructure. The control module has a multi-position key switch having a by-pass position permitting pivoting of the guard without de-energizing the motor. This permits difficult cuts to be made which would not be feasible with the guard in place. An anti-kickback pawl is also provided within the guard and prevents the saw from rejecting a workpiece in a direction opposite to its feed direction.
