Latest Patents

Jeffrey L Ng holds a patent for a blowing agent metering system. This invention provides a method for controlling the rate of introduction of blowing agent into polymeric material during processing. The system is designed to form a mixture with the desired blowing agent weight percentage. It includes a restriction orifice positioned between a blowing agent source and a blowing agent port within a foam processing apparatus. The metering system measures the pressure differential as the blowing agent flows across the orifice and can also measure the temperature at various locations. By utilizing a pre-determined relationship between flow rate, orifice dimensions, and measured variables, the system's controller adjusts the upstream pressure to maintain the desired blowing agent flow rate.
