Abstract: An apparatus for removing debris from between and around teeth including a main body member having first and second ends and a flossing implement operably associated therewith. The flossing implement is detachably connected to the main body member. The flossing implement includes first and second ends. The first end of the flossing implement is disposed adjacent the first end of the main body member. The second end of the flossing implement is removed from the first end of the main body member. The second end of the flossing implement includes first and second tines and an intermediate section connecting the first and second tines. The first and second tines each include projections for receiving the corresponding ends of the flossing material extending therebetween. Alternatively, or in addition, the first and second tines may be formed hollow and the intermediate section provided with an opening for receiving a removable flossing cartridge.

Abstract: The present invention generally relates to fluid powered brushes. A preferred embodiment is directed to a toothbrush powered by water enroute to a shower head. The toothbrush includes a handle and an operating head detachably connected thereto. A plurality of brush heads are positioned adjacent the operating head. A fluid driven impeller is disposed upstream of the outlet of the shower head. A flexible cable is connected at one end to the impeller and at the other end to the brush heads. The flexible cable rotates upon rotation of the impeller to drive the brush heads. A fluid powered toothbrush formed in accordance with the preferred embodiment of the present invention is adapted to efficiently drive multiple brush heads. Furthermore, no fluid need be drawn off the shower to power the toothbrush.

Abstract: A preferred embodiment of the present invention is directed to an automatic dental flosser having a housing which includes a handle and an operating head. The operating head includes a pair of hollow tines which extend in a first plane. A flossing assembly is operably associated with the operating head for removing debris from between and around teeth. The flossing assembly includes a support member for supporting a flossing material. A first portion of the support member is disposed in the hollow tines while a second portion of the support member is removed therefrom. A drive member is operably associated with the first portion of the flossing assembly for linearly displacing the support member. A stop is provided intermediate the upper and lower surfaces of the hollow tines for regulating the proximity of the flossing material to the oral tissues of an individual. Further, an adjustable protective cover encases the second portion of the support member which is removed from the hollow tines.

Abstract: A toothbrush conditioning device comprises a body member having an upper end; a cover member having a first orientation mounted to the upper end for forming with the cover member a conditioning chamber and a second orientation remote from the upper end for providing access to the body member; lamp means disposed proximate the toothbrush for conditioning the toothbrush when the cover member is in the first orientation; fan means for ventilating the chamber; control means operably associated with the lamp means and the fan means for causing automatic intermittent operation of the lamp means and for causing automatic operation of the fan means for a preselected time when the cover member is in the first orientation; and switch means operably associated with the cover member, the body member and the control means for permitting operation of the control means, the lamp means and the fan means when the cover member is in the first orientation and for preventing operation thereof when the cover member is in the seco

Abstract: A true mass fuel gaging system for aircraft utilizing multiplexing of tank unit measurements in or adjacent a fuel tank for improved accuracy and fault isolation. The system provides dual equipment channels for redundancy throughout all data processing portions of the system and also uses extensive built-in testing (BIT) routines so that upon detection of a fault an alternative channel can be switched into use. Detected fault locations are displayed in the cockpit with the fuel quantity displays. The system also provides displays of center of gravity measurements derived from fuel mass and location.

Abstract: The method of repairing a tooth involves positioning a selected medium contiguous a location of the tooth to be repaired, placing a heat-shrinkable overlay around the tooth for covering the selected medium, heating the overlay to a temperature sufficient to cause shrinkage thereof and thereby operating on the medium. The overlay is subsequently removed to expose a repaired tooth requiring little or no additional post-cure finishing.

Abstract: A toothbrush conditioner includes a body having an upper end. A cover member is removably mounted to the upper end for therewith providing a conditioning chamber. A support plate is positioned within the body member for selectively positioning a toothbrush to be conditioned within the chamber. An ultraviolet radiation source is carried by the cover member and is movable therewith for being selectively positioned within the chamber proximate the brush to be conditioned when the cover member is mounted to the upper end. A plurality of vent openings are in the body member. A control device is in connection with the radiation source for causing selective intermittent operation thereof.

Abstract: A standardized, modular, fuel quantity gaging system suitable for use with aircraft having a plurality of fuel tanks. The system utilizes a standard electronic module, preferably located on the front spar of the center wing box, to house a redundant, centralized, microprocessor-based electronic assembly. This assembly processes the tank-generated fuel quantity signals and produces a digital data stream which is distributed to display units in the cockpit and at the refueling control panel. The digital signals are transmitted over two 2-wire data busses from the standard electronic module to the cockpit and to the refueling panel. One of these buses is active, the other being held in standby, for use as needed. The two busses are part of separate data processing channels extending between the fuel quantity signal multiplexers in the standard electronic module and the indicators in the cockpit and at the refueling panel.

Abstract: This apparatus includes means for measuring capacitance or resistance and means for simulating a selected capacitance value. The apparatus is connectible into a fuel gaging system. When so connected, a selector switch can be operated to make the normal connections between the fuel gaging capacitors and the indicators, so that the indicators produce their normal responses. Alternatively, the selector switch may be operated so that the apparatus measures the capacitance or resistance of various elements in the gaging system. As another selection, a simulated value of capacitance may be inserted in the gaging system to make the indicators in that system respond to the simulated value in addition to the capacitance of the fuel gaging capacitors of the gaging system.
