Latest Patents

Gianella's latest patents include a closed loop powder flow regulator. This innovative powder feeding system features closed loop regulation of the powder feed rate. It utilizes a feed gas discharged under constant pressure into an enclosed hopper. A valve is strategically placed to constrict a carrier conduit that conveys powder in a carrier gas. A load cell measures the rate at which powder flows from the hopper through an intake orifice into the carrier conduit, producing a filtered flow rate signal. A first controller generates a reference signal that represents the difference between a set point signal and the flow rate signal. Additionally, a differential signal is created based on the pressure difference between the hopper pressure and the carrier conduit pressure. A second controller then produces a control signal that adjusts the valve to proportionately constrict the carrier gas stream, thereby regulating the powder flow rate. The design ensures that the time constant of the second controller is faster than that of the first controller.

Another significant patent involves a system and method for measuring the flow rate of powdered material from a container. This system produces a first analog signal representing the weight of the container, which is then differentiated to obtain a second signal corresponding to the flow rate. The second signal is processed through an adaptive filter that includes two low-pass filters with varying time constants. The combination signal is scaled to indicate the powdered material flow rate, enhancing measurement accuracy.
