摘要:
A motor/damper assembly installable on the top end of a fuel-fired water heater includes a support plate structure upon which a flue collar with a pivotally supported flue damper, a drive motor, and a drive shaft interconnecting the motor damper are mounted. The assembly is installed by placing the collar over the upper end of the water heater flue, securing the support plate structure to the top end of the water heater, and positioning a top cover housing on the support plate structure. Using the assembly provides improved support rigidity and alignment for the motor and shaft relative to the damper, improved repeatable precise manufacturing placement of the motor and shaft, improved construction aesthetics, with the cover also protecting the shaft from shipping and handling damages.

摘要:
A tube disposed in the combustion chamber of a standing pilot type fuel-fired water heater is used to increase the overall efficiency of the water heater by improving the heat transfer from the pilot flame to the tank during standby periods by funneling the standing pilot flame upwardly through the tube in a manner concentrating the pilot flame heat against an underside portion of the bottom head of the water heater tank. To further increase water heater efficiency, the pilot burner is of a dual input type. Various pilot burner operational algorithm modes are disclosed for causing the pilot burner to operate at a high firing rate during main burner operation, and at a low firing rate during standby periods.

For improving the accuracy of a speech recognition system, for the specific task of character recognition, the character that is to be recognized or interpreted, is spoken in accordance with this invention, using simple coding-schemes that result in acoustic renderings that are well separated in the acoustic space. Furthermore, to relax the constraint on users for memorizing multiple words associated with multiple characters, in one embodiment, the coding-schemes are defined based on a combination of the given character and its neighboring/succeeding character(s).

摘要:
The present invention relates to extended release pharmaceutical compositions of Levetiracetam and processes for preparing the same. The extended release tablet of Levetiracetam is with a core comprising of Levetiracetam and water dispersible rate controlling polymer, and the tablet core is optionally functional coated comprising a combination of water non-dispersible and/or water dispersible polymer. It provides extended therapeutically effective plasma levels over a twenty four hour period with diminished incidences of neuropsychiatric adverse events by eliminating the troughs and peaks of drug concentration in a patient's blood plasma. The composition also exhibits no food effect.

摘要:
A system comprising a first double data rate (DDR) memory device, a second DDR memory device coupled to the first DDR memory device, the second DDR memory device not using a delay locked loop (DLL) device to synchronize clock signals. The system further comprises a logic coupled to the first and second DDR memory devices. The logic is adapted to receive data from the first and second DDR memory devices by way of a single conductive pathway.
