Title: **Frederick J Walker: Innovator in Vehicle Technology**
Introduction
Frederick J Walker, an accomplished inventor based in Banbury, GB, has made significant contributions to the field of vehicle technology. With three patents to his name, Walker's innovations focus on advanced mechanical systems designed to enhance vehicle performance and safety.
Latest Patents
Walker’s most recent patents include the development of viscous shear couplings and a vehicle anti-skid braking apparatus. The viscous shear couplings are engineered for controlling the action of interaxle or interwheel differential gears in vehicle transmissions. They consist of a series of interleaved annular plates that can float axially in a viscous liquid-filled enclosure. This design utilizes a spring-loaded piston to adjust the enclosure volume dynamically, allowing for a tailored torque-transmitting characteristic based on temperature changes.
His vehicle anti-skid braking system enhances driver control during sudden braking situations. The system operates by adjusting the brake-applying effort via a reversible servo-booster, which reacts to signals from an anti-lock sensor. The design incorporates dual diaphragm actuators to either assist or oppose braking effort, effectively minimizing the risk of a driver overriding the anti-skid operation during emergencies. A modified configuration with a single diaphragm actuator is also available for situations where skidding occurs.
Career Highlights
Walker has had a noteworthy career, contributing his expertise to well-known companies such as Harry Ferguson Limited and GKN Transmissions Limited. His work in these organizations has further established his reputation as an innovative engineer focused on vehicle technology.
