Abstract: Fuel activation apparatus for use in the pretreatment of fuel that is to be mixed with air for burning in combustion engines and the like. Fuel within a dielectric carrier is subjected through use of a field coil or other means to pulsed energy from an oscillator or other source at a frequency in a range corresponding to resonant frequencies for the molecular components of the fuel, the constituent elements of the fuel or protons of such elements. For fuels having a hydrogen constituent, operation in a frequency range of 16 to 42 Mega Hertz is suggested. For fuels having other inclusions, the operating frequency range may be expanded to include the nuclear resonance frequency for such components.

Abstract: The rough hewn bench plane attachment of the present invention allows a standard bench plane to be converted into a hewing tool that is able to create hewn lumber similar in shape and design to hand-hewn lumber. The attachment incorporates a chassis assembly mounted under the front knob of the bench plane. An eccentric rolling assembly connects to the chassis assembly and causes an eccentric rolling effect as it rolls over the lumber. This eccentric movement of the wheels causes the bench plane to correspondingly move in an eccentric manner with respect to the workpiece so that a cutting iron of the invention replacing the regular cutting iron of the plane generates varying depth gouges in the lumber workpiece. The cutting iron of the invention has an arcuate cutting edge that enhances the hewing of the lumber by varying the transverse depth of the cutting edge in the lumber workpiece.
