  • System for replacing the water cooled laser in a microplate reader
    Patent number: 8826519
    Abstract: The present invention relates to a method and system for repairing and refurbishing a microplate reader of the Flipr type which has a water cooled argon laser light source. The old laser is removed and replaced with a high power (300 to 500 mW) air cooled solid state laser as a replacement place on its own support and focused and wired to replace the old laser. The new product operates at lower power consumption yet provides accurate measurements.

  • Method and system for replacing the water cooled laser in a microplate reader
    Patent number: 8347478
    Abstract: The present invention relates to a method of refurbishing a microplate reader such as a FLIPR type microplate reader by the replacement of the water cooled laser with an LED source which provides a relatively homogeneous light and operating performance comparable to the laser light source.

  • Methods and apparatus for cooling gas turbine engine combustors
    Patent number: 6986253
    Abstract: A method facilitates the operation of a gas turbine engine that includes a combustor including a combustion chamber. The method comprises supplying fuel to the combustion chamber, and directing compressed airflow through a combustor dome assembly that includes a splashplate and a unitarily formed flare cone, such that at least a portion of the compressed airflow is channeled axially downstream through at least one cooling passage defined between the flare cone and the splashplate for cooling of the dome assembly.

  • COMBUSTER SWIRLER ASSEMBLY
    Publication number: 20050039458
    Abstract: Aunitary swirler assembly that provides improved service life, having a ferrule body and a unitary swirler body. The unitary swirler body has oppositely-directed primary swirler passages and secondary swirler passages. A pair of rails formed on the unitary swirler body engage the ferrule body to limit relative movement, and prevent relative rotation, of the ferrule body and the unitary swirler body.

  • Combustor swirler assembly
    Patent number: 6453671
    Abstract: Service life is improved in a swirler assembly including a primary swirler and a secondary swirler having a venturi formed thereon and being disposed in engagement with the primary swirler. First and second rails are formed on the secondary swirler and are positioned to engage the primary swirler and thereby prevent relative rotation of the primary and secondary swirlers.
