Title: Innovations of Charles A. Farel
Introduction
Charles A. Farel is a notable inventor based in Boulder, Colorado. He has made significant contributions to technology, holding a total of 3 patents. His work primarily focuses on enhancing the functionality of machines and electrical devices.
Latest Patents
One of Farel's latest patents is a document feeder for moving bed machines such as copiers. In this invention, a roller at the bottom of a sloped ramp rests on the upper surface of a reciprocating original document handling carriage. Documents placed on the ramp slide downward until the leading edge reaches the nip between the roller and carriage surface. The movement of the carriage pulls the document from the tray onto the carriage surface for scanning. An additional roller can be included to provide automatic document ejection by pushing the document onto an output tray as the carriage returns.
Another significant patent is the flux controlled shunt regulated transformer. This invention regulates the output voltage of a transformer by controlling the flow of magnetic flux through a shunt core. The transformer includes a main core fabricated from U-I laminations, arranged to form a substantially rectangular structure. A primary and a secondary coil are seated on the main core. A shunt core with shunt winding, having lamination size and structure substantially analogous to that of the main core, is positioned in spaced alignment to the main core. A flux interconnecting path, called the bottleneck, connects the main core and the shunt core to form a sturdy unified structure. The shunt winding is activated by control circuitry, limiting the flux flow through the shunt core and thereby regulating the output voltage.
