Abstract: An appliance and method for non-thermal heater protection during prolonged operation of the appliance is provided. A time limit determination apparatus may prevent prolonged operation heater protection that prevents significant damage to the appliance.

Abstract: An apparatus for cutting materials and more specifically an improved saw blade includes a plurality of variable teeth thereon. The variable tooth saw blade cuts faster and smoother while reducing harmonic vibrations. Specifically, the teeth on the saw blade are grouped into sections with differing circumferential widths and differing spacing between the sections.

Abstract: A router bit with a position stop is disclosed. The router bit includes a body with a collar extending outwardly from it and a shaft extending outwardly from the collar. At least one cutter blade is mounted to the body and the cutter blade may be used to cut a profile into a workpiece. The collar has a first diameter, the shaft has a second diameter and the first diameter is larger than the second diameter. The collar has a face formed a spaced distance or height from the transition point between the collar and the body. The face rests against the upper surface of a chuck when the shaft is secured in the chuck. This allows the body and hence the cutter blades to be held a predetermined distance above the upper surface of the chuck. A second router bit may be provided to cut a complimentary second profile in a second workpiece.

Abstract: A device for finishing a surface includes a body member with a contoured exterior surface and adapted to couple with a shaft. At least two surface portions, positioned at different radial distances from an axis of the body member, define the contoured exterior surface. Each surface portion includes an abrasive member to finish a surface. In another aspect, a device for finishing a surface includes a body portion with an exterior surface configured to finish a surface formed by a rotary cutter. The exterior surface has a profile that substantially corresponds to a profile of a surface formed by the rotary cutter. A coupling member is coupled to the body portion and adapted to be coupled to a rotary drive mechanism to transmit rotational energy to the body portion.

Abstract: A composite circular saw blade. In an exemplary embodiment, a circular saw blade includes a body generally circular in shape including an aperture and an outer periphery. The aperture being generally defined in the center of the body and configured to be at least partially received by a circular saw arbor body. Further, a plurality of teeth are disposed around the outer periphery of the body for providing a cutting edge. The body is formed of a composite material, the composite material including two or more structurally complementary substances in which one of the two or more structurally complementary substances is a matrix material.
