Latest Patents
Among his most recent advancements, Rice holds patents for two key inventions:
1. **Vibration Dampener for Direct Acting Pressure Regulator**
This innovative drop compensated pressure regulator features a spring casing that houses both a regulator spring and a relief spring. It incorporates a diaphragm sandwiched between a lower casing and the spring casing. The design includes inlet and outlet ports, along with a one-piece cam stem and relief seat. This unique assembly moves with the diaphragm, providing a cam surface that engages a movable disk holder. The cylindrical lower spring seat is linked to the spring casing by an O-ring, which effectively dampens vibrations. Additionally, built-in stops on the cam stem help retain its position within the orifice tube.
2. **Flow Restrictor and Diverter for Direct Acting Pressure Regulator**
In this invention, a metallic gas pressure regulator comprises a spring casing and a lower casing that enclose a diaphragm. The lower casing features aligned inlet and outlet ports. A one-piece plastic cam stem and relief seat operate in conjunction with the diaphragm, interacting with a movable plastic disk holder. Notably, the orifice tube can accommodate a removable plastic boost end cap to enhance diaphragm action. A unique pressure relief mechanism is positioned within the diaphragm, incorporating a metal disk with a flow-restricting hole and a flow diverter to mitigate risks in case of destruction of the plastic orifice tube.
