He has made significant contributions to the field of packaging machinery, holding three patents that showcase his innovative spirit and technical expertise. His work primarily focuses on improving the efficiency and functionality of bulk material handling systems.

Latest Patents

One of Hill's latest patents is the "Bi-leaved valve apparatus," designed for controlling bulk material flow from a metering apparatus. This apparatus features a cylindrical flow tube with an axial material passageway, an outlet, and a flow tube actuation surface. The valve support is mounted around the flow tube, allowing for relative rotation. The bi-leaved design includes leaves that seal the flow tube outlet and can be moved between open and closed positions. An actuator facilitates the rotation, enabling precise control over the flow of materials.

Another notable patent is the "Apparatus for metering and packaging bulk particulate material." This device consists of several cups that rotate around a shaft, positioned to receive bulk material from hopper outlets. As the cups rotate, they alternately dump measured portions of material into weigh buckets, which then feed a packaging machine. This innovative design enhances the efficiency of the packaging process by ensuring that each portion is accurately measured and packaged.
