Did You Know...
...that several people are credited with the invention of the flush toilet? Most people have heard of Thomas Crapper (1837-1910), the sanitary engineer who invented the valve-and-siphon arrangement that made the modern toilet possible. Another claimant to "the throne" was British inventor Alexander Cumming who patented a toilet in 1775. Then there's a nameless Minoan (a native of ancient Crete) who lived 4,000 years ago who supposedly was ahead of his time and created the first flush toilet!

It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractThe invention provides a temperature control device with excellent temperature uniformity and thermal response, which can be manufactured easily, and a manufacturing method for the same. A thermoelectric device 21 is arranged between a substrate mounting plate 1 and a cooling plate 3. Copper foil electrodes 5, 5, . . . on the upper side of the thermoelectric device 21 are adhered to a lower surface of the substrate mounting plate 1 with an adhesive sheet 17 covering substantially the entire lower surface of the substrate mounting plate 1, and copper foil electrodes 7, 7, . . . on the lower side of the thermoelectric device 21 are adhered to an upper surface of the cooling plate 3 with an adhesive sheet 19 covering substantially the entire upper surface of the substrate mounting plate 1. The total thickness of the adhesive sheet 17 and the copper foil electrodes 5 adhering to it, and the total thickness of the adhesive sheet 19 and the copper foil electrodes 7 adhering to it, is each set approximately 25 to 1000 μm thin, so as to make the thermal resistance sufficiently low. Thermoelectric conversion elements 9 and 13 are distributed across a large area covering at least the entire area corresponding to the substrate 2. | InventorsApplicationNo. 685805 filed on 10/11/2000US Classes:62/3.7, Including specific circuitry or heat exchanger material136/204, Including additional heat exchange means257/E23.082Cooling arrangements using Peltier effect (EPO)Field of Search62/3.2, Thermoelectric; e.g., peltier effect62/3.3, Heat pump, selective heating and cooling62/3.7, Including specific circuitry or heat exchanger material136/203, Peltier effect device136/204, Including additional heat exchange means136/225Having strip, film or plate-type thermocouplesExaminersPrimary: Doerrler, William C.Attorney, Agent or FirmUS Patent References4420364, High-insulation multi-layer device formed on a metal substrateIssued on: 12/13/1983 Inventor: Nukii , et al.4735847, Electrically conductive adhesive sheet, circuit board and electrical connection structure using the same Issued on: 04/05/1988 Inventor: Fujiwara , et al.5588300, Thermoelectric refrigeration system with flexible heatconducting element Issued on: 12/31/1996 Inventor: Larsson, et al.5605048, Method of cooling an object with a thermoelectric battery cascade Issued on: 02/25/1997 Inventor: Kozlov, et al.5737923, Thermoelectric device with evaporating/condensing heat exchanger Issued on: 04/14/1998 Inventor: Gilley, et al.5802856, Multizone bake/chill thermal cycling module Issued on: 09/08/1998 Inventor: Schaper, et al.5956569, Integrated thermoelectric cooler formed on the backside of a substrate Issued on: 09/21/1999 Inventor: Shiu, et al.6000225, Two dimensional thermoelectric cooler configuration Issued on: 12/14/1999 Inventor: Ghoshal6096965Quantum well thermoelectric material on organic substrate Issued on: 08/01/2000 Inventor: Ghamaty, et al.
