Latest Patents

One of her latest patents is a method of making a composite barrier can for a magnetic coupling. This invention is designed to prevent leakage between the inner magnet assembly attached to industrial magnetic drive pumps and the outer magnet assembly connected to the pump drive or motor. The composite barrier can is made from non-metallic materials, specifically a combination of fiber and resin, which includes a pole piece. This innovative design allows for high-speed and high-pressure pump operation while minimizing eddy current generation. Additionally, it reduces heat development in the coupling area and decreases the horsepower required from the motor. A resistance temperature detector is strategically positioned on the exterior or within the fiber layer of the can, ensuring accurate temperature monitoring.

Another significant patent by Cramer involves a method of making wear-resistant material lined housings. This method outlines the process of manufacturing a two-piece metal housing with wear-resistant interior surfaces. The steps include machining a slightly oversized shape into the assembled housing, applying a hard material to the inner surfaces, and then reassembling and machining the housing to precise dimensions. The wear-resistant materials used can include ceramic, tungsten carbide, or high-velocity oxy-fuel (HVOF) applied hard-coating.
