Abstract: An electric double-layer capacitor is provided which is larger in electrostatic capacitance, and can be much higher in rated voltage, than that in the prior art using a liquid electrolyte solely composed of an ionic liquid. Having an electrolyte and electrodes, the capacitor incorporates an atom encapsulated fullerene or an atom encapsulated fullerene salt in the electrolyte. The electrolyte can either be a liquid solution or a solid. With the electrolyte being a solid, cations of the atom encapsulated fullerene or atom encapsulated fullerene salt may either be made movable or static in the electrolyte.

Abstract: An air freshening device is made from a solution of a polymer and a fragrant material, which is applied to an air permeable substrate. A solid fragrant residue is formed on the substrate. A fragrant material diffuses from the residue for scenting flowing through and about the substrate. Means are provided for attaching the substrate to an air filter received in a forced air heating, ventilating, and cooling system.

Abstract: An air freshener device disposed in proximity to a ceiling fan by attachment to a pull chain of the ceiling fan for scenting air moved by the fan. The device receives a scented pad in a first dish that defines a pair of opposite slots for receiving links of the pull chain for securing the device in close proximity to the ceiling fan and for overlying the scented pad in the first dish. A second dish joins to the first dish by engaging a flange on the second dish to a groove in the first dish. The groove is defined by a rib which extends outwardly of a thinner distal portion of the skirt and a thicker portion of the skirt. The dishes define a plurality of vent openings for exposing the scented pad to air moved by the ceiling fan. A first tab extends outwardly of the first dish and a second tab extends outwardly of the second dish in partially overlapping relation, whereby the joined dishes are separated by twistingly moving the tabs in opposite directions.

Abstract: An air freshener device disposed in proximity to a ceiling fan by attachment to a pull chain of the ceiling fan for scenting air moved by the fan. The device has a unitary clam-shell housing for receiving a scented pad between a first dish and a second dish which join together by an intermediate foldable hinge. The dishes define a plurality of vent openings for passage of air therethrough for scenting. A latch member extending laterally from the first dish defines a channel for lockingly engaging a post that extends radially inwardly on the second dish upon folding the dishes together along the hinge. A pair of oppositely aligned slots in portions of the first dish receiving links of the pull chain for securing the device in close proximity to the ceiling fan and for overlying the scented pad in the housing.
