    Abstract: A turbine nozzle for a gas turbine engine includes a nozzle segment having an airfoil-shaped vane with a root, a tip, a leading edge, a trailing edge and opposed curved pressure and suction sides. An arcuate inner band segment is attached to the root of the vane. The inner band segment includes an inner flowpath surface bounded at forward and aft ends thereof by a forward-facing surface and an aft-facing surface, respectively. A convex curved blended corner is formed between the inner flowpath surface and the aft-facing surface.

    Abstract: A method and apparatus for forming articles made of polyurethane. The apparatus includes a polyol weigh tank, an isocyanate weigh tank, an additive tank and a mix tank enclosed by a vent chamber. The vent chamber is in communication with inlet and outlet pipes to move air and fumes from the interior of the vent chamber past a filter. The apparatus further includes a containment vessel also having inlet and outlet pipes for movement of air and fumes. The containment vessel is in communication with a pump for creating a vacuum in the vessel to reduce pressure in the interior of the vessel in which a mold is placed. The method includes the steps of: creating a vacuum around a mixture of at least one polyol, at least one isocyanate and at least one additive, to lower the pressure on the mixture below atmospheric pressure as the mixture expands; allowing the mixture to expand; reducing the vacuum to increase the pressure on the mixture in proportion to any further expansion of the mixture caused by the generation of a blowing influence in the mixture; and returning the pressure to atmospheric pressure.

    Abstract: An apparatus for manufacturing articles made of polyurethane that includes a mold assembly in communication with a mix chamber. The mix chamber is positioned below the mold assembly. The mix chamber includes a propeller for mixing the liquid polyurethane chemicals. The mix chamber further includes a pneumatically actuated bladder that causes the mixed chemicals to move from the mix chamber to the mold assembly. The chemicals expand to take on the shape of the mold. The method of the present invention comprises the steps of: (a) selecting polyurethane chemicals having certain specific weights; (b) placing said chemicals in a mix chamber wherein chemicals stratify according to their specific weights to prevent detrimental reaction among the chemicals until final mixing; and (c) allowing the chemicals to expand to form an article.

    Abstract: A process for the production of an open cell polyurethane foam comprises the mixing of the following components at ambient temperatures in a mixing zone: a diisocyanate having a functionality of at least about 2.0, at least one hydrogen donor, at least one surfactant which is effective in forming an open cell polyurethane foam, at least one catalyst, and a blowing agent comprising a gas having a boiling point below approximately -100.degree. F. at atmospheric pressure which preferably comprises carbon dioxide. In addition, the mixture may also optionally contain water. The mixture is subjected to a pressure in said mixing zone which is sufficient to maintain the blowing agent in the liquid state at ambient temperatures. After mixing, the mixture is ejected from the mixing zone to atmospheric pressure, thereby completely and instantaneously vaporizing the blowing agent to provide expansion of the mixture. The resultant foam is then cured at ambient temperatures.
