Title: Method and apparatus for low nox combustion of gaseous fuels
Inventor: BRADY ROBERT T
IPC: F23L7/00
Filed: 1992-08-21
Granted: 1997-02-25
Abstract: A method and apparatus for low NOX combus-tion of natural gas in a compact steam boiler having output steam delivery controlled by predetermined outlet steam pressure.  The compact boiler employs a small high heat release combustor discharging into a forced draft convective heat exchange section.  In operation, the compact boiler is completely and auto-matically self-operating, employing flue gas recircu-lation (FGR) wherein the FGR is admitted into the burner combustion air through a valve controlled by boiler flue gas NOX content. A novel bell mouthed flue gas scoop is utilized in the boiler stack up-stream of the NOX sensor.  In an alternate combustion chamber design, a cylindrical water wall coil sur-rounds the combustion process, increasing boiler effi-ciency through the inherent large temperature differ-ence between the coil and the combustion in process, along with reducing the combustion temperature and further reducing the NOX content of combustion prod-ucts.  A further variation in the combustion system utilizes a ceramic shield surrounding a natural gas burner as it fires into the compact combustion cham-ber.  Primary and secondary combustion air are admit-ted to the combustion chamber through first stage combustion internal of the shell and second stage combustion occurring internal of the boiler combustion chamber.

Abstract: The business form assembly includes an integrated mailer and return envelope comprising first, second, third and fourth plies having first, second, third and fourth edges. The first and third edges of the four plies are adhesively secured one to the other.      Additional lines of adhesive are inset from a tear strip containing the adhesive securing the first, second, third and fourth plies to one another for securing the second and third plies to one another. The second and third plies are inset along second and fourth edges to enable adhesive securement of the first and fourth plies along the first and fourth edges to one another. A return envelope flap is formed by a fold line in the third ply.      A registering line of perforations in the second ply defines the back face of the return envelope and a record-keeping portion between the line of perforations and the fourth edge. Upon detachment of that record-keeping portion and insertion of it, together with other materials, in the return envelope, the return envelope may be returned to the sender. Thus, the mailer with return inserts may be formed solely of four plies.      A fifth ply is used as a fly sheet.

Abstract: Successive pixels representing video data in successive lines in a raster scan are buffered. Each of the lines has a sync pulse defining the line beginning. A phase adjustment is determined between the sync pulse, preferably at a particular level in the sync pulse, and an adjacent one of system adjacent clock signals at a particular frequency. The actual or expected phase adjustment between the pixels at the end of each line is also determined. The difference between the phase adjustments at the beginning and end of each line is then determined. Progressive adjustments are made in the phase of each successive pixel in the line relative to the system clock signals in accordance with the number of system clock signals in the line and the determined difference in the phase adjustment between the line beginning and end. In this way, the pixels of video data are synchronized with the system: clock signals. When the actual phase adjustment relative to the system clock signals is determined at the end of each line, the difference in the phase adjustments at the beginning and end of such line is determined from the phase adjustment for such line and the phase adjustment stored for the previous line. When the expected phase adjustment is provided for the end of each line, this estimated value is altered for each line by an amount equal to the actual phase adjustment at the beginning of such line and the estimated phase adjustment at the end of such line.

Title: In-flow coriolis effect mass flowmeter
Inventor: KALOTAY PAUL ZOLTAN
IPC: G01F1/00
Filed: 1994-01-18
Granted: 2002-07-02
Abstract: A mass flowmeter is disclosed having a flow tube inserted within the confines of a conduit containing a material flow. Mass flow information is derived for the material flow within the conduit by generating mass flow information for the material flowing within the smaller flow tube positioned within the conduit and then by adjusting the calculations for the flow tube to represent mass flow information for the conduit. In accordance with a first embodiment of the invention, a pressurized cover is positioned around the flow tube to isolate the exterior surface of the flow tube from the material in the conduit. The space between the exterior of the flow tube and the cover is pressurized to a pressure equal to that of the material in the conduit. Both sides of the flow tube walls are at the same pressure so that a flow tube comprised of thinner and more flexible material may be used. In accordance with a second embodiment of the invention, the cover is not used and the flow tube is inserted directly into the conduit and the exterior walls of the flow tube are in contact with the material within the conduit. This embodiment is advantageous in applications in which the conduit material is of low viscosity. The embodiment with the pressurized cover is ideally suited for use in applications with heavy viscosity material.
