  • Optimized internal manifold heat shield attachment
    Patent number: 7765808
    Abstract: A fuel manifold assembly for a gas turbine engine includes an annular fuel manifold having at least one fuel conveying passage and defining at least one slow fuel flowing location. A heat shield at least partly encloses the fuel manifold and a plurality of intermittent joints attach the heat shield to the fuel manifold. The joints are circumferentially distributed about the fuel manifold as far away from the slow flowing location as possible while maintaining the fuel manifold dynamically balanced.

  • Method for preparing gels
    Patent number: 7754229
    Abstract: The formation of a cream and gel is described using a biopolymer, such as a polyhydroxyalkanoate (PHA), a polylactide (PLA), a polylactideglycolide (PLGA) and a polyglycoside (PGA), or a derivative thereof, in a latex form with the addition of a binder, which is generally an amphiphilic chemical entity. An hydrophobic domain of the amphiphilic chemical entity interacts with at least one biopolymer forming a water soluble complex, while the hydrophilic domain of the amphiphilic chemical entity maintains the soluble complex in suspension in an aqueous solution, which after proper heating becomes a gel or a cream. As a result, a versatile gel or cream is created with different compositions and textures that are obtained based on the nature of the binder used and the ratio of biopolymers and binder(s).
