摘要:
A system and method are disclosed for high temperature protection of combustor and other components by controlling the temperature of combustion chamber gases in a fuel cell system tail gas burner using a nozzle or plurality of nozzles to inject water or water vapor upstream, downstream or directly into the combustion chamber. A variable speed pump, actuated valve or other flow metering device regulates the supply of water or water vapor to the nozzles. For the case of water vapor, an evaporator is required between the pump and nozzles. Flow regulation is effected by a control algorithm that reacts to combustor temperature, changes in the power production of the fuel cell system and/or other related system parameters.

A method of making flow feature structures for a micro-fluid ejection head. The method includes the steps of laser ablating a nozzle plate material to provide an elongate fluid chamber and fluid supply channel therein for connecting the fluid chamber with a fluid supply. The fluid chamber has a first length and a first width. An elongate nozzle hole is laser ablated in the nozzle plate material co-axial with the fluid chamber. The nozzle hole has entrance dimensions having a longitudinal axis dimension and a transverse axis dimension such that the longitudinal axis dimension is from about 1.1 to about 4.0 times the transverse axis dimension.

An improved system for upgrading new and existing gates or barriers to provide improved crash barrier rating. This system comprises a reinforcing attachment to the gate or barrier and improved reinforced bollards with catch hooks to absorb the energy of impact. The reinforcing attachment is an arrangement of cable and structural members that provide for increased reinforcement by ensuring that the load is distributed on the cable to minimize the risk of breakthrough as a result of cable failure. The bollards have been improved by strengthening the catch hook attachments and adding reinforcement positioning elements to facilitate proper assembly.

An embodiment of the present invention includes a technique to improve stability of a pellicle. The pellicle is pre-baked at a predetermined temperature substantially below a glass transition temperature. The pre-baked pellicle is purged with an inert gas. The purged pellicle is radiated by a radiation at a wavelength. In another embodiment, a chamber is sealed with a pellicle membrane which divides the chamber into first and second compartments. The chamber has an inflow opening in the first compartment and an outflow opening in the second compartment. A gas is injected into the inflow opening and penetrates the pellicle membrane to the outflow opening. In another embodiment, the chamber has first inflow and outflow openings and second inflow and outflow openings in the first and second compartments, respectively. A first gas is injected into the first inflow opening and a second gas into the second inflow opening. The first and second gases have a permeability difference. The first gas penetrates the pellicle membrane to the second outflow opening.
