IPC: H02N11/00
Filed: 1996-07-12
Abstract: The present invention provides a thermoelectric unit that reliably burns the input fuel and transfers the generated heat efficiently to a thermopile for conversion into usable electrical power. The unit is compact and is able to achieve a high reliability, at low cost, because of the simplicity of the design.      The burner will start and run on the optimum lean fuel/air mixture and does not require any adjustment either while operating or upon restarting, under either hot or cold conditions.   The design of the exhaust chimney prevents external wind from either inhibiting or extinguishing the flame. The fuel orifice and venturi are designed to prevent flame flashback from occurring.      The burner, heat collection fins and the hot plates for heat transfer to multiple thermopiles are integrated into one compact casting.       These novel features of the present invention result in a thermoelectric converter with higher conversion efficiency, higher reliability, greater simplicity and significantly lower cost than present technology offers.

Abstract: A curable organopolysiloxane composition that maintains flowability under moisture-free and light blocking conditions is described. It more rapidly forms a nonflowable adhesive when irradiated with high energy beams such as ultraviolet rays and electron beams, and forms an elastic body by further curing when exposed to atmospheric moisture. A method for adhering a substrate to an adherend using the composition is also claimed. The curable organosiloxane composition has a viscosity of 3,000 Pa.s or less and is made up of a silicone resin containing no alkenyl groups, a polydiorganosiloxane having terminal units containing a mercapto group, an alkenyl-containing organopolysiloxane, and a condensation catalyst. An assembly which has a substrate adhered to an adherend is made by spreading the composition on the substrate, irradiating it with a high energy beam, contacting the irradiated surface with an adherend, and letting it stand in air, so that the substrate is adhered to the adherend.

Title: Toothbrush storage device
Inventor: BJELAN BRENDA L
IPC: A46B17/04
Filed: 1997-06-02
Abstract: A device that stores and sanitizes toothbrushes in individual storage pockets in a vessel containing a sanitizing solution. Each storage pocket is formed in the top surface of the vessel in such a manner that the storage pocket is partially filled with sanitizing solution and in normal use, the pocket is sealed from the sanitizing fluid contained in the main vessel. When the sanitizing solution has served its useful life in the pockets of the vessel, the vessel is overturned, the used sanitizing liquid in each of the pockets is dumped out by over-turning the vessel. The vessel is then returned to its normal orientation, and the top of the vessel is raised slightly to allow the top of each pocket to slightly separate from the lower portion of each pocket to allow the sanitizing liquid in the vessel to flow into each pocket to replenish the sanitizing fluid in each pocket. When each pocket is filled to the desired level, the top of the vessel is returned to its sealing position and locked in this position until the solution in the pockets is spent.
