Abstract: A fuel-fired water heater has a combustion chamber disposed beneath the storage tank portion of the water heater. The bottom side wall of the combustion chamber is defined by an annular perforated wall structure with a perforated mounting plate structure being removably secured to the underside of the wall structure over the central opening therein. A burner and associated pilot/thermocouple assembly are secured to the upper side of the mounting plate and project upwardly into the combustion chamber, with the piping and wiring of the burner and pilot/thermocouple assembly extending externally beneath the combustion chamber, outwardly through a side wall access passage, and then turning upwardly along the outside of the water heater for connection to a thermostatic fuel valve. To remove the bottom plate-mounted burner and pilot/thermocouple assembly the fuel supply piping must first be decoupled from the thermostatic valve, thereby assuring that the access plate cannot be removed while the burner is firing. The combustion chamber is essentially sealed to prevent combustion air inflow thereto except through the perforations in its bottom side wall structure. These perforations are configured and sized to permit upward combustion air inflow therethrough into the combustion chamber with a minimal pressure drop, while also acting as flame arrestors to hinder downward flame flow therethrough potentially caused by upward inflow of flammable vapors and subsequent ignition thereof within the interior of the combustion chamber.

Title: Environmentally compatible solid film lubricant
Inventor: NOVAK HOWARD L
IPC: C10M111/04
Filed: 1998-12-18
Granted: 2007-07-10
Abstract: A solid film lubricant useful for aerospace and other heavy machinery applications comprising a mixture of boric acid and molybdenum disulfide in a polymeric binder comprising a silicone polymer and an epoxy resin is provided. Boric acid and compounds related to boric acid can be effectively used as inorganic lubricant components in solid film lubricants in place of graphite thereby avoiding galvanic corrosion induced by graphite. The boric acid containing solid film lubricant provides superior lubrication at the high stress levels common for booster rockets and other aerospace applications, but without inducing galvanic corrosion, or exposing workers and the environment to toxic materials such as lead compounds. In addition, it affords substantial savings in labor, due to the need for only one coat, and savings in energy due to the substantially lower cure temperature of about 450°F compared to 1000°F for a currently used two coat ceramic system. There is also a significant savings in time, hazardous waste disposal costs and human protection costs by using the boric acid containing SFL.

Abstract: In methods and apparatus for suppressing echo of a far end signal (114) encoded using LPC-based compression in a near end signal (112) encoded using LPC-based compression, parameters of each frame of the near end encoded signal (112) are processed without synthesizing a speech signal from the near end encoded signal (112) to determine whether sufficient echo to merit echo suppression is present in the frame. Upon determining that insufficient echo to merit echo suppression is present in the frame, the parameters of the frame are passed unmodified. Upon determining that sufficient echo to merit echo suppression is present in said frame, the parameters of the frame are modified without synthesizing a speech signal to suppress echo in the frame. The methods and apparatus are particularly suitable in codec bypass applications.

Abstract: In a code division multiple access (CDMA) communications system, a PN sequence generating device (310) is provided to generate a PN sequence by interleaving (322, 332, 342) of cyclically shifting the symbols of an orthogonal or biorthogonal code (320, 330, 340) in accordance with a pre-defined hopping pattern (360). A receiver receives simultaneous signals from a plurality of transmitters, where each transmitted signal is spread by a PN sequence generated from the same pre-defined hopping pattern. The receiver is able to differentiate the received signals from each transmitter by varying the amount of interleaving or cyclic shift in each transmitted signal. In the PN sequence generating device (310), an orthogonal symbol generating portion (320, 330, 340) cyclically shifts mutually orthogonal and periodic orthogonal code sequences, and an orthogonal symbol selector (350) selectively outputs the cyclically shifted orthogonal symbols according to a predetermined pattern.
