摘要:
A leak detection system for detecting a leak within a duplex valve assembly is disclosed. The duplex valve assembly includes a first valve, a second valve and an intermediate fluid flow passageway fluidly interconnecting the first valve to the second valve. The leak detection system includes a means for indicating whether the first valve is maintained in a closed position or an open position, a means for indicating whether the second valve is maintained in a closed position or an open position, and a pressure change detector within the intermediate fluid flow passageway. The pressure change sensing means is at least partially positioned within the intermediate fluid flow passageway for detecting a pressure change within the intermediate fluid flow passageway.

In a system including a gas source, a target cylinder for receiving gas, a conduit for carrying gas, and a valve for controlling the flow of gas, a method of dosing the target cylinder with gas is disclosed. The method comprises the step of calculating a mass flow rate for dosing the conduit and the target cylinder. The valve is biased to an open position to permit gas to flow through the conduit and into the target cylinder. The mass flow rate and the cumulative mass of gas flowing through the conduit are measured using a mass flow meter. The valve is biased to maintain the measured mass flow rate of gas flowing through the conduit substantially equivalent to the calculated mass flow rate. The valve is biased to a closed position once the measured cumulative mass of gas is substantially equivalent to the pre-determined mass of gas.

A pressurized cylinder containment unit is provided. The pressurized cylinder containment unit comprises a support structure including means for receiving a shelf. The shelf receiving means is/are defined along at least a portion of a height dimension of the support structure. At least one shelf is provided for supporting the one or more pressurized cylinders. The at least one shelf is moveably positionable along the height dimension of the support structure. The at least one shelf includes mounting means for selectively mounting to the shelf receiving means of the support structure at different height elevations.

A wagering game is played on processor-based gaming apparatus including: providing a gaming apparatus of processor, video display and gaming input system; after a wager, the processor executes code to play a first wagering game and display images associated with the first wagering game on the video display; when the processor recognizes a predefined trigger outcome, bonus play of a second game different from the first wagering game begins; the processor identifies bonus points accumulated during bonus play distinct from any wagering credits; the processor displays at least two distinct bonus events of a first bonus event played on the first wagering game and a second bonus event played on the first wagering game. The first bonus event and the second bonus event being activated by the processor diminishing accumulated bonus points. An amount of bonus points needed to activate the first bonus event is different from an amount of points needed to activate the second bonus event.

An electronic gaining system moderates payout rates by the processor randomly providing a first random outcome which determines whether the wager is initially resolved by the processor as a winning outcome, tie outcome or losing outcome. The processor recognizes specific ones of, but less than all of the tie outcomes and/or the losing outcomes as belonging to a provisional subset of the outcomes and/or losing outcomes. The processor recognizes a random outcome as within the provisional subset, the processor randomly selecting from among multiple additional outcomes stored in memory for at least individual ones of random outcomes within the provisional subset, and randomly selecting a final random outcome for the at least individual one of the random outcomes within the provisional subset from a second set of random outcomes that includes at least one winning outcome, and resolving the wager on the basis of the final random outcome.

The invention relates to materials used as electrodes and/or catalysts, as well as methods associated with the same. The materials may comprise an alloy or intermetallic compound of a transition metal (e.g., Ni) and a metal additive (e.g., Sn). The transition metal and additive are selected to provide improved electrode and/or catalytic performance. For example, the materials of the invention may have a high catalytic activity, while being less susceptible to coking than certain conventional electrode/catalytic materials. These performance advantages can simplify the equipment used in certain applications, as well as reducing energy and capital requirements. Furthermore, the materials may be manufactured using traditional ceramic processing methods, without the need for complex, unconventional fabrication techniques. The materials are particularly suitable for use in fuel cells (e.g., SOFCs electrodes) and in reactions that use or produce synthesis gas.
