Abstract: A fuel/air mixing apparatus, such as a main swirler assembly (400) comprising a sleeve (410), provides for additional air entry around the perimeter of a bore (440) through which passes a fuel/air mixture. The additional air reduces or eliminates flashback during operation of a gas turbine comprising the assembly (400). In some embodiments, a plurality of gaps (464) exists between spaced apart tabs (462) along a downstream end (460) of the sleeve (410). During gas turbine operation, air flows through both a flashback annulus (411) and the gaps (464). In other embodiments, a plurality of holes are placed upstream and in line with the tabs (1004) to supplement the air flow through gaps (1006). In yet other embodiments, rows (1102) of holes (1104) are provided to supplement the airflow. Downstream ends (460,1218) may interface with a downstream-oriented lip (460) or with an upstream-oriented lip (1224). The interfacing may comprise a fit effective to damp vibration and to increase the natural frequency.

Abstract: Network servers in a cluster share the same network protocol address for incoming client requests, and in a data link layer protocol a reply of a client to a request from a server is returned to this same server. For example: (1) ports of the servers are clustered into one single network channel used for incoming and outgoing requests to and from the servers; or (2) ports of the servers are clustered into one single network channel used for incoming requests to the servers and a separate port of each of the servers is used for outgoing requests from each of the servers; or (3) logical ports of the servers are clustered into one network channel used for requests to the servers and a separate logical port of each of the servers is used for outgoing requests from each of the servers.

Abstract: A gate assembly for an animal passageway has two barriers that, when in use, are in close proximity to each other in a closed position and can be moved in opposing directions to each other to be in an open position. The operation of the gate assembly to the open position is achieved by an operator using an operator-activated control mechanism. At least one barrier is configured so that when in the open position it does not intrude into the passageway and activation of the control mechanism is external to the passageway. The gate assembly is maintained in the open position until the operator operates the control mechanism to close the grate assembly. When the assembly is in the open position one barrier is in an upper position with respect to the other. The barrier are pivotally attached to a support at separate pivot points.

Abstract: In its optimal form this type of structure possesses a streamlined aerodynamic profile in one direction and convex shaped shell type closure components in the orthogonal direction The main load carrying member of the system, the truncated ellipse structural rib provides most of the streamlined aerodynamic profile and the rest is provided by concave surfaces connected externally to the extremities of the ribs. Where it is possible, the truncated ellipse structural ribs and the rest of the streamlined aerodynamic profile are aligned with the anticipated direction of maximum wind velocity. Under self weight and superimposed dead loads, the structural response of the truncated elliptical rib is characterized by beam action in the middle area of the member, then increasing arching action (thrust) as the rib curvature increases, with further increasing in bending and shear action as the extremities of the rib are approached.

Abstract: A gate assembly (1) for a passage way having two barriers (4, 5), wherein the barriers are in close proximity to each other when in a closed position, and can be moved in opposing directions to each other to be in an open position, characterised in that at least one barrier is configured so that when in the open position it does not intrude into the passageway.

Abstract: An apparatus for delivering dissolved chlorine dioxide into a water system comprises sources for acid, a chlorite, and a chlorine donor solutions and metering pumps. The solutions are mixed whereby chlorine dioxide is generated, which is then fed into a water system.

Abstract: A solution for genenting chlorine dioxide is disclosed. Th solution comprises a chlorlte, a chlorite donor, an alkali and water. The chlorine dioxide is released by adding an acid to the solution. Also disclosed are methods for preparing and using the solution.

Abstract: A solution for generating chlorine dioxide comprises a chlorite, a chlorine donor, an alkali, and water. Substantially all of the chlorite is converted to chlorine dioxide upon acidification of the solution. Methods for preparing and using the solution are based on such solution.
