摘要： A power planer having a base, a carriage assembly and a height scale. The carriage assembly includes a cutterhead that may be adjustably positioned relative to a datum that is defined by the base. The height scale has a rotary scale that rotates in response to movement of the carriage assembly relative to the base. A value of a displayed portion of the rotary scale is related to a distance between the cutterhead and the base.

摘要： A power supply for high voltage, low current gas discharge tubes such as neon, argon, and mercury vapor. A free running, flyback oscillator, converts D.C. voltage energy into radio frequency energy by means of a compact, ferrite transformer and associated circuitry. The primary winding is tuned by a resonant capacitor and driven by a power transistor. A high voltage, centertapped winding of a ferrite transformer drives the gas tube load directly. A feedback winding arranged across the transistor base and emitter junction sustains oscillation and controls the drive level of the transistor by means of a regulating circuit which controls the amplitude of the current. Oscillator starting is achieved by means of an on-off switch which supplies a single starting pulse to the power transistor or by means of a time delayed starting pulse. A MOSFET transistor connected to the power transistor base and a current sensing transformer arranged in series with the primary winding, disables the power transistor momentarily at the end of a conducting cycle. Charge carries are depleted in the base-cathode region, resulting in resetting the transistor quickly such that it can withstand a forward voltage of 700 volts in the off state.

摘要： A power tool having a base assembly with a first portion, which defines an upper surface, and a second portion that defines a lower surface. The first and second portions may be castings and are coupled to one another without machining the upper surface of the first portion or the lower surface of the second portion. After assembly of the base portion, the upper surface of the second portion is machined to define a flat reference surface. Construction of the power tool in this manner provides a robust base assembly that is relatively inexpensive to manufacture. A related method is also provided.
