With a total of three patents to his name, Firth has developed methods and apparatuses that enhance the efficiency of material handling and processing.

Latest Patents

One of Firth's latest patents is a "Method and apparatus for conveying and metering solid material." This invention features a solid material pump that includes a pump housing with an inlet and an outlet. The passageway between these components is defined by a movable friction drive wall and a stationary wall. The friction drive wall has a larger surface area for contacting the solid material, allowing it to exert greater frictional forces on the material than the stationary wall. This design enables the material to be conveyed in a forward direction without jamming, as it behaves semi-hydrostatically. The apparatus also allows for metering the flow of solid material using conventional techniques.

Another significant patent is the "Retort seal mechanism with integral bearings." This invention improves the design of rotating retort seals by incorporating integral bearings that align the seals relative to the sealing surface of the rotating vessel. By separating the sealing function from the bearing alignment function, Firth's design extends the life of the seals and enhances sealing performance. The alignment bearings are strategically positioned to prevent damage from processed materials, and a lubrication passageway ensures both the bearings and seals are adequately lubricated.
