Abstract: Two-cycle, single vane impeller, hinged hub rotary engines are simple embodiments of a new class of engines. The 2-cycle, hinged hub rotary engines have dependently rotating impellers with, interdigitated, alternating hub sections, a hinge like rotation joint. These 2-cycle engines have expansion and exhaust cycles. The intake and compression cycles are performed by a synergistic air compressor (fan or piston type). Fuel and oxidizer (e.g. compressed air, from a synergistic air compressor,) are injected, to create combustion mixtures, and spontaneously ignited to start the expansion cycle in the minimized expansion sector(s).

Abstract: Rotary, electromagnetic, internal combustion, engines utilize magnetic fields, generated by electromagnets, to control the momentum of dependently rotating impellers.

Abstract: Continuous, monoatomic thick graphite sheets/ribbons are potentially produced utilizing laser desorption techniques. These techniques and other are generalized toward production of continuous, monoatomic/molecular thick materials.

Abstract: A laser light pulse is used to create a minuscule image of an alphanumeric symbol.

Abstract: Footware dressings containing fluorocarbons in a carrier base plus optional colorants and additives. These dressings create a relatively slick and non-stick surface with excellent "contamination" resistance.
