Title: Operational process and its improved control system of a secondary air burner
Inventor: ANDERSON KIM A
IPC: F23G7/06
Filed: 1997-12-10
Granted: 2006-11-07
Abstract: Control system and method for monitoring and controlling the stoichiometry o f a secondary air burner in a thermal oxidizer. The burner control system secures a certain stoichiometry independent of possibl e simultaneous changes of the gas mixture flow rate and/or of the combustible impurity concentration in the process gas. The firing rate o f the burner is adjusted by a controller. Additionally, the flow of the burner fuel and of the process gas mixture are measured and transform ed into separate signals. Both signals are sent to an evaluation apparatus that compares the signals and generates a third signal based upon that comparison. This third signal is in communication with a device that changes the gas mixture flow resistance, and thus the desired amount of gas mixture will be diverted for the combustion of the fuel.

Title: Novel resin-curing process enabling the actinic radiation cure of resins containing shieldings against actinic radiations; composition for the process, moldings, and molding process
Inventor: HAYASHI SHUNICHI
IPC: B29C70/06
Filed: 1998-10-15

Abstract: A method is provided to completely cure a resin composition highly capable of screening energy radiation, such as a carbon fiber-reinforced composite material (CFRP), simply by exposing the resin composition to UV radiation in the presence of a specific photopolymerization initiator system (reaction catalyst system) comprising at least two components. To this end, the present invention provides a resin curing method wherein, when a resin composition is exposed to energy radiation typified by UV radiation, another kind of first energy than the energy from an energy radiation source is autogenously generated within the resin, and the same kind of second energy is successively generated by the autogenously generated energy, so that the resin composition is cured by means of the first and second energies, or both the first and second energies and the energy from the energy radiation source, whether or not the resin composition contains a substance capable of screening energy radiation.

Title: Method of making an absorbent member
Inventor: GENTILE VICTOR MICHAEL
IPC: D04H1/70
Filed: 2000-03-21
Granted: 2007-11-06
Abstract: A method for making an absorbent member is disclosed. The method includes introducing fibers into an air stream to form an air-fiber mixture. This air-fiber mixture is then directed to a porous media having a first surface. The air-fiber mixture contacts the first surface and the fibers collect on the first surface and forms a fibrous mat. The air passes through the first surface and can be recovered and recycled, if desired. The air-fiber mixture is then terminated or diverted so that the fibrous mat can be removed from the first surface. The fibrous mat is wetted by water to obtain a desired moisture content.  Finally, the wetted fibrous mat is compressed to a predetermined thickness to form an absorbent member, which has unique expansion properties.

Abstract: A surge detection system for detecting a surge occurred at a compressor of a gas turbine aeroengine having a turbine connected to the compressor. In the system, the ratio between the compressor outlet pressure and its differential and the differential of the turbine inlet temperature (or the ratio between the turbine inlet temperature and its differential) are calculated. Then, the calculated value are multiplied together and the product is compared with a threshold value. When the product is less than the threshold value, it is determined that a surge occurred at the compressor. With this, a surge occurred at the compressor and a magnitude or degree of the surge occurred may be accurately detected.
