| 20090064587 | NOZZLES FOR USE WITH GASIFIERS AND METHODS OF ASSEMBLING THE SAME - A method for assembling a nozzle is provided. The method includes providing an injection tube that includes an outlet that is configured to discharge fuel therefrom. A face plate is also provided that extends about the injection tube such that the face plate substantially circumscribes the outlet. A cooling chamber is defined within the injection tube and configured to channel cooling fluid adjacent to the face plate. At least one surface defining the cooling chamber is configured to disrupt a flow of the cooling fluid flowing through the cooling chamber. | 03-12-2009 |
| 20090129967 | FORGED AUSTENITIC STAINLESS STEEL ALLOY COMPONENTS AND METHOD THEREFOR - A forgeable austenitic stainless steel alloy and forging process capable of producing forged components that exhibit mechanical and environmental properties and metallurgical stability suitable for use in thermally and chemically hostile environments, such as the environment of a component of a gas turbine engine shroud assembly. The alloy contains, by weight, 18.0 to 22.0% chromium, 8.0 to 14.0% nickel, 4.0 to 7.0% manganese, 0.4 to 0.6% silicon, at least 0.2 up to 1.0% nitrogen, at least 0.05 up to 0.075% carbon; up to 0.3% molybdenum, up to 1.0% niobium, up to 0.2% cobalt, up to 4.5% aluminum, up to 0.1% boron, up to 0.1% vanadium, up to 1.0% tungsten, and up to 5.0% copper, with the balance iron and incidental impurities. | 05-21-2009 |
| 20090133462 | FORGING DIE AND PROCESS - A forging die and process suitable for producing large forgings, including turbine disks and other rotating components of power-generating gas turbine engines, using billets formed by powder metallurgy. The forging die includes a backplate, and segments arranged in a radial pattern about a region on a surface of the backplate. Each segment has a backside facing the backplate and an interface surface facing away from the backplate, with the interface surface being adapted to engage the billet during forging. The segments are physically coupled to the surface of the backplate in a manner that enables radial movement of the segments relative to the backplate. | 05-28-2009 |
| 20100050521 | METHODS TO FACILITATE COOLING SYNGAS IN A GASIFIER - A method of cooling syngas in a gasifier is provided. The method includes channeling cooling fluid through at least one tube-bundle that includes at least three tubes coupled together within a radiant syngas cooler and extends through a reaction zone of the gasifier, and circulating reactant fluid around the at least one tube-bundle to facilitate transferring heat from the reactant fluid to the cooling fluid. | 03-04-2010 |
| 20110027120 | DEVICE AND METHOD FOR HOT ISOSTATIC PRESSING - Improved methods and containers for forming billets using hot isostatic pressing are provided. The methods and containers have features that control the deformations of the container during the high temperatures and pressures experienced in such processing so that the loss or removal of material from the resulting billet can be optimized. | 02-03-2011 |
| 20110044839 | DEVICE AND METHOD FOR HOT ISOSTATIC PRESSING CONTAINER HAVING ADJUSTABLE VOLUME AND CORNER - An improved container and method for forming billets using hot isostatic pressing is provided. The method and container allows for adjusting the volume of the container so as to obtain a billet of the desired shape based on selected powder charge for the container. In addition, the corner of the container can be adjusted to allow for elimination of edge effects and further shape control in the resulting billet. | 02-24-2011 |
| 20110044840 | DEVICE AND METHOD FOR HOT ISOSTATIC PRESSING CONTAINER - An improved method and container for forming billets using hot isostatic pressing is provided. The improved method and container have features that control the deformations of the container during the high temperatures and pressures experienced in such processing so as to provide a billet having a predetermined shape such as, for example, substantially parallel, convex, and/or concave sides. Conservations of the powder used for the billet and more efficient use of the container upon the resulting billet can be achieved. | 02-24-2011 |
| 20110052441 | METHOD AND DEVICE FOR HOT ISOSTATIC PRESSING OF ALLOYED MATERIALS - A method and container for forming billets using hot isostatic pressing is provided. The method and container prevent or minimize the diffusion of metals between a high value powder alloy and the container used for hot isostatic pressing. In one exemplary embodiment, a diffusion barrier is placed on the container between the powder and the container to control diffusion therebetween. | 03-03-2011 |
