Title: The Innovative Mind of Alex Zelczer
Introduction
Alex Zelczer is a notable inventor based in Cleveland Heights, Ohio. He holds an impressive portfolio of 13 patents, showcasing his contributions to the field of engineering and technology. His work primarily focuses on control systems and fluid flow mechanisms, reflecting his expertise and innovative spirit.
Latest Patents
Among his latest inventions is the "Modulating Bypass Control System and Method." This control system is designed for a bypass duct and includes a pneumatic damper control assembly, a sensor, and a pneumatic switch. The damper control assembly features a damper vane that can move between open and closed positions to regulate airflow. The position of the damper vane is controlled through pressure applied via a damper control line. The sensor, mounted on the supply duct, transmits a pneumatic supply duct signal based on air pressure or velocity. The pneumatic switch then opens or closes the connection between the damper control line and the supply line based on the difference between the pneumatic supply duct signal and the combination of pneumatic pressure from the damper assembly and a switch biasing pressure.
Another significant patent is the "Fluid Flow Control Damper Assembly." This assembly includes a damper vane and a piston actuator, designed for easy installation even when the outer surface of a duct is inaccessible. The piston actuator features a powder metal piston that fits closely within a glass cylinder, which connects to a pneumatic control system. A drive rod links the piston to the damper vane, allowing it to move between open and closed positions.
