Title: The Innovative Contributions of Philip H Pegram
Introduction
Philip H Pegram is a notable inventor based in Leamington Spa, GB. He has made significant contributions to the field of pneumatic tire technology, holding a total of 3 patents. His work focuses on enhancing safety and performance in tire systems.
Latest Patents
One of Pegram's latest inventions is a pressure indicator for pneumatic tires. This device provides a clear, positive indication of a predetermined pressure loss through the exposure of a brightly colored element within a transparent dome. The design ensures that all moving parts are fully enclosed and protected against dirt and corrosion. The element can be masked or unmasked by an opaque shield mounted on a piston, which is biased by a spring to unmask the element but can be displaced by tire pressure to mask it. In preferred embodiments, the piston is located between the inner and outer parts of a second piston, which responds to tire pressure acting on its upper surface.
Another significant invention by Pegram is a thermal fuse device designed for deflating a pneumatic tire in the event of high temperature. This device features an outlet for the molten eutectic plug, which is separated from the air outlet to prevent venting air from re-solidifying the eutectic. The eutectic plug abuts a step or shoulder to prevent 'creep', ensuring reliable operation under extreme conditions.
