Title: Innovations by Robert A. Fellows in Fire Detection Technology
Introduction
Robert A. Fellows is an accomplished inventor based in San Ramon, California, known for his significant contributions to fire detection technology. With a total of two patents to his name, Fellows has developed innovative solutions aimed at enhancing safety in various environments.
Latest Patents
Fellows' latest patents include an "Apparatus for detecting a fire having a liquid filled sensor tube" and a "Pressurized extinguishant release device with rolling diaphragm." The first patent describes a fire detection system that utilizes an elongated liquid-filled tube equipped with a fluid-coupled alarm switch. This system features a flexible diaphragm that detects changes from liquid to vapor phase in the presence of overheating or fire conditions, triggering an alarm. To mitigate false alarms caused by normal liquid expansion due to temperature changes, a compensator is integrated into the design. This compensator can take various forms, including mechanically coupled bellow-type containers or a bimetallic bellows, ensuring accurate detection during fire conditions.
The second patent outlines a pressurized extinguishant release device that employs a rolling diaphragm. This device consists of a closed elongated sensor tube filled with a mixture of water and ethylene glycol. When the temperature of the liquid-filled sensor tube rises, vapor pressure acts on the diaphragm head, causing a shear pin to fail. This action propels a penetrator into a brittle membrane, allowing the extinguishant to flow and effectively combat the fire.
