  • Publication number: 20050257051
    Abstract: Information streams are integrated with context information objects and processing instruction objects. The integrated information streams are received by a solution manifold and transformed in accordance with the context information objects, the instruction objects, and logic inherent in the solution manifold. The transformed information is then viewed by a client of the solution manifold. The client may also impose different transformation rules and context information on the transformed information and return those transformation rules and context information to the solution manifold to revised the manner in which integrated data is subsequently transformed. Additionally, the solution manifold logic may be overruled by the instruction objects and/or updated by the instruction objects.

  • Publication number: 20040255777
    Abstract: In order to connect a pneumatic booster (S) to a brake pedal (F), it is necessary to fix a control rod (1) of the booster (S) to the brake pedal (F). This fixing is made difficult because of the location of the booster which is located in the engine compartment and because of the location of the brake pedal (F) which is located in the cabin of a vehicle. In order to make it easier to fix the booster (S) to the brake pedal (F), a method for the rigid and blind fixing of the brake pedal (F) to the control rod (1) of the booster is provided. This result is obtained by nesting two nesting portions (2, 3) of a control rod (1) which are connected respectively to the booster and to the brake pedal. The two portions are held one inside the other using a spring clip (25) housed in a circular groove (26). This elastic attachment device also allows play to be taken up and allows the mounting to be stabilized.

  • Publication number: 20040071877
    Abstract: Annular substrates (20) are stacked in an enclosure where they define an inside volume (24) and an outer volume (26) outside the stack. A gas containing at least one precursor of a matrix material to be deposited within the pores of the substrates is channeled inside the enclosure to a first one (24) of the two volumes, and a residual gas is extracted from the enclosure from the other one (26) of the volumes. One or more leakage passages (22) allow the volumes to communicate with each other, other than through the substrates. The total section of the leakage passages has a value lying between a minimum value for ensuring that a maximum gas pressure in the first volume is not exceeded until the end of densification, and a maximum value such that a pressure difference is indeed established between the two volumes from the beginning of densification.
