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.

System for replacing the water cooled laser in a microplate reader

Method and system for replacing the water cooled laser in a microplate reader

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.

A unitary 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.

Combuster swirler assembly

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.

Methods and apparatus for cooling gas turbine engine combustors

A combustor liner has an annular shell which includes a first portion and a second portion. The first portion is provided with slot film cooling and the second portion is provided with multi-hole film cooling. The multi-hole cooling portion can be located either forward or aft of the slot film cooling portion, depending on the nature of the combustor that the liner is to be used in. In one possible embodiment, the liner includes a first annular panel, a second annular panel section joined at its forward end to the aft end of the first panel section, and a third annular panel section being joined at its forward end to the aft end of the second panel section. At least one of the panel sections has multi-hole film cooling and at least one other of the panel sections has slot film cooling.

Hybrid film cooled combustor liner

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.

Combustor swirler assembly

A retainer segment is provided for a swirler assembly having first and second members, such as a primary and secondary swirler or a swirler body and floating ferrule, disposed in sliding engagement with each other. The two members are maintained in sliding engagement by two of the retainer segments which are joined to the second member and engage the first member. Each retainer segment is an arcuate member defining inner and outer curved edges and first and second ends. Each end has a concave cutout formed therein to reduce weld joint and bending stresses that occur from the forced vibration of the retainer segments.
