    Abstract: A saw blade includes a circular core having a plurality of cutters disposed along a periphery thereof, and a central bore configured to receive an arbor of a rotating power tool. A plurality of gullets is located in spaced relation between the cutters, extending radially inward from the periphery. Each of the gullets includes a neck portion defined by side walls extending radially inward and extending divergently from one another into an arcuate base. The arcuate base extends along concave arcs to a linear base portion disposed at a radially innermost portion thereof, and which intersects a radius of the saw blade.

    Abstract: A multi-pole circuit breaker comprising a single main housing containing multiple circuit breakers for protecting multiple branch circuits. Each of the circuit breakers comprises a single line terminal for receiving electrical current from a utility line, a plurality of load terminals for supplying electrical current from the single line terminal to a plurality of branch circuits via load lines, and a plurality of neutral terminals for receiving electrical current returned from the branch circuits via neutral lines Line conductors inside the main housing connect the line terminal to the plurality of load terminals. Sensors inside the main housing generate signals representing characteristics of the electrical current flow in the branch circuits, and a signal processor uses the signals generated by the sensors for detecting abnormal conditions in the branch circuits and generating trip signals in response to the detection of an abnormal condition. A single tripping mechanism between the line terminal and the load terminals receives the trip signals and interrupts the flow of current to the branch circuits in response to a trip signal.

    Abstract: This invention relates to a circuit interrupting device having a trip button for disconnecting a load from a source of electrical power and a reset button for resetting the device after it has tripped. When the device is operating in its reset state, a source of electrical power is connected to a load through a set of contacts located within the device. The contacts are held closed by the spring loaded reset button which holds captive and urges a latch plate to move up to close normally open contacts. In the preferred mechanical trip mechanism, depressing the trip button causes the latch plate to move forward and be released from the reset button. The latch plate, upon being released from the reset button moves down to allow the contacts, which are biased to be normally open, to assume their normally open position. At this time, pressing the reset button initiates an electrical cycle which causes the normally open contacts to close only if the device is operating properly and there is no fault on the line. The device described is mechanically tripped and electrically reset, and it can be tripped without power being supplied to the device.

    Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include a reset lock-out mechanism are provided. The reset lock-out mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism used to break the connection is non-operational or if an open neutral condition exists.
