Abstract: Hearing aids are enhanced by application of liquids thereto, said liquids being solvents for organic matter, or wax, or ear canal wax. The liquids are volatile. Application of the liquids to both the hearing dome ends and the ear canal surfaces create a coupling thereof, which maintains a desired position of the aids within the ear canals.

Abstract: An electrical generator and a method of generating electricity are achieved by utilizing a disc-shaped permanent magnet having opposite faces with opposite magnetic poles. The magnet is rolled through a passageway having electrically conductive conductors that intersect the magnetic flux lines of the rolling magnet, thereby generating electrical voltage and current in the conductors. This system can be included in a wide range of products or devices to self generate therein operating or stored electrical power, especially products or devices that are portable by a human being or other living creature.

Abstract: Enhanced internal electrical generators are provided which include pole pieces that form air gaps flanked with conductive wire coils. Rotatable armatures supporting permanent magnets are arranged to swing or revolve relative to the air gaps such that the magnetic flux thereof is intersected by the wire coils to generate electrical voltage and current therein. These generators may be incorporated within the housing of many portable devices such as cell phones to self generate electrical current useful for operating the device or recharging its batteries or other component that stores the generated electrical energy.

Abstract: Self powered cell phones are operated with a rotatable crank shaft, the rotary motion of which is translated by cam or slotted slider crank-driven gear trains into pivoting motions of an internal armature, in reciprocal alternating opposite directions, whereby one or more conductive wire coils, supported by the armature, are caused to intersect the magnetic flux of one or more permanent magnets disposed within the cell phones, thereby generating electrical voltage and current for operating, charging or recharging the cell phone batteries. Recharging mechanisms are provided which can be manually or flywheel operated to impart the pivotal motions of the armature and supply the current generated therein directly to the cell phone batteries.

Abstract: A method and apparatus are provided for reducing pollutants in the exhaust gases produced from the combustion of a fuel by introducing hydroxyl and associated radicals and oxidizers into at least one of the precombustion and postcombustion gas stream of the combustion engine upstream of the catalytic converter and treating the exhaust gases with the catalytic converter.
