Latest Patents
One of his notable inventions is the "Volumetric Measuring Apparatus." This invention provides an acoustical volumetric measuring apparatus that utilizes a variable volume standard cavity. The variable volume standard cavity is formed of a threaded two-piece cylinder, which changes volume upon rotation of one piece relative to the other. This design allows for simplified comparisons in determining the volume of an unknown cavity, enabling the use of less expensive components.
Another significant patent is the "Brake Proportioning Valve for a Motor Vehicle." This brake valve is interposed in the brake line between the master cylinder and the rear wheel brakes. It is constructed to limit the fluid pressure at the rear brakes relative to the pressure at the front brakes during the application of master cylinder pressure. The valve includes an inertia sensor that senses the rate of vehicle deceleration and modulates the pressure ratio between the front and rear brakes accordingly. This mechanism compensates for the load carried by the vehicle, affecting the relative effectiveness of the front and rear brakes.
