Latest Patents

One of Siegwarth's latest patents is a chemical injection system and chemical delivery process/method of injecting into an operating power reactor. This innovative system is designed to deliver a chemical solution into a reactor through feedwater system taps during normal operating conditions. The delivery process utilizes positive displacement pumps, allowing for the injection of a concentrated solution that is internally diluted by the system before discharge. This method minimizes chemical loss, enables the use of higher concentrated solutions, and simplifies the laborious process of chemical dilution. Additionally, it raises the chemical solution to the necessary pressure for injection and prevents solid precipitations at the injection pump head.

Another significant patent is the method and apparatus for measuring electrochemical corrosion potential inside small shallow cracks. This method involves using a detecting device with an ECP detecting array to measure the electrochemical corrosion potential of a material specimen. The process includes establishing a flow through the detecting device and measuring the electrical potential between the device ground and an electrode wire.
