Abstract: A wing foil bearing may include one or more wing or tab foil layers. A tab foil layer may comprise a thin material with a two-dimensional array of tab shapes. A tab shape may be defined by a boundary of material separated from the thin material and having an integral edge and a free edge. Tab shapes may include one or more free-state bends relative to the thin material, forming a two-dimensional array of cantilever wings or tabs. Tab arrays may be one or more of various types or two-dimensional arrays, and a tab foil layer may include additional tab arrays and tabs. One or more tab foil layers may be engaged with a mounting surface layer and a counter-surface layer to form a wing foil bearing. Tab foil layers may be stacked and or nested, including partial nesting and complete nesting.

Abstract: A process of information certification is provided. The process includes receiving a request from a user, such as an individual, group, or entity, and dividing the categories into two parts. Checking and certification is performed by a Host where possible on existing categories of subject matter. Additional categories are generated for new information to be checked and certified. Certifications are provided for all categories which can be and have been checked. The certification process is continued in the future—either automatically and/or upon request—to include any new information provided by the user or found in regular searches.

Abstract: A method and apparatus is disclosed for the high-speed production of foundry cores of the type in which a foundry aggregate is mixed with a curable binder, preferably an isocyanate or phenolic material, to form a core mixture which is carried within a hermetically sealed core box and is hardened by the introduction into the core box of a gaseous curing agent, preferably an amine. A positive displacement pump pumps a predetermined amount of liquid amine from a holding tank to a vaporizer where it is heated and completely vaporized. The vaporized curing agent is forced from the vaporizer by the introduction of an inert gas, preferably nitrogen, and the mixture of the inert gas and the vaporized curing agent is entrained in a low pressure air stream which carries it to the core box, thereby curing the core. After the core is cured, valves close to stop the flow of the low pressure air stream, the mixture of inert gas and curing agent to the low pressure air stream, and the flow of inert gas to the vaporizer.
