Abstract: A burner fuel mixer head includes a primary housing and a secondary housing. The primary housing has a fuel/air mixing chamber with a mixed fuel gas inlet. The secondary housing has a fuel mixing, chamber. A venturi throat with converging sidewalk is positioned in the mixed fuel gas inlet of the primary housing. A venturi nozzle communicates with a pressurized fuel gas inlet with a first end of the venturi nozzle extending into the fuel mixing chamber in axial alignment with the venturi throat. This forms a venturi, such that a pressurized flow of pressurized fuel gas through the venturi draws low-pressure fuel gas from the fuel mixing chamber of the secondary housing through the mixed fuel gas inlet into the fuel/air mixing chamber of the primary housing.

Abstract: Techniques are described for space-time-frequency (STF) coding of multi- carrier transmissions over frequency-selective fading channels. In particular, techniques for STF coding of MIMO-OFDM systems are described that provide maximum diversity, high coding gains, and low decoding complexity are described. A set of generally correlated OFDM subcarriers are divided into groups of subcarriers creating a set of group STF (GSTF) subsystems, within which STF coding is applied to each GSTF subsystem. Subcarrier grouping preserves maximum diversity gains and simplifies both the code construction within each GSTF and decoding complexity. ST coding techniques are used in designing STF block (STFB) and STF trellis (STFT) codes which are applied within GSTF subsystems.

Abstract: In a method for manufacturing instant lottery tickets where book numbers and ticket numbers are printed on the tickets utilizing a dual security process such that the book numbers are shuffled in each pool before the tickets are printed to break the link between the book numbers the ticket numbers or validation numbers, a reversing process can be used under certain predefined conditions to relate the original book numbers to the ticket numbers or validation numbers. In one example, where a shuffling algorithm utilizing seeds is used to shuffle the book numbers, the seeds used in the algorithm are maintained in an encrypted file. A decryption key for the encrypted seed file can be used by a lottery administration or trusted third party to reconstruct game play indicia for game adjustment purposes and manufacturing adjustments. To enhance security, the independent third party can also be used to administer the encryption and decryption keys during the ticket manufacturing process and during life of the instant ticket game.

Abstract: An apparatus (10) and method for producing dry beads of a liquid reagent for use in various methods of analysis. The beads are formed by use of an x-y table (18) that can be translated along both the x and the y axis. An insulated tray (20) containing liquid cryogen is positioned atop the x-y table. A metal grid (24) forms a plurality of cells (22) in the tray so that the cryogen is free to enter the cells (22) up to the level of the cryogen i n the tray (20). The frozen drops form into beads and freely amass on the bott om of the tray (20). A drop forming device (34) dispenses individual drops to fall by gravity into an individual, discrete cell (22). The table (18) then translates to position another discrete cell (22) for receiving the subseque nt drop of reagent. The movement of the x-y table (18) causes agitation of the cryogen to enhance the freezing process.

Abstract: Changes occurring downhole during a fracturing process can create or reflect pressure signals. Capturing and evaluating such pressure waves during fracturing enables personnel to monitor, in real time or later, what happens downhole. When a fracture extends, a burst of acoustic noise is embodied in a pressure wave or signal, as is noise coming from other sources. By transforming time-based pressure signals to a frequency base, one can monitor this acoustic noise. In a particular implementation, a waterfall plot of frequency spectra at successive time slices of the original signal is used to determine frequency ridges, such as a ridge of decreasing frequencies indicates fracture extension and a ridge of increasing frequencies indicates either closure or proppant backing up in the fracture. Filtering, such as wavelet filtering, can be used. A fracturing process can be controlled in response to determining whether the fracture is extending.
