Latest Patents
Marshall's latest patents include:
1. **Gear pump with gears having curved teeth and method of feeding elastomeric material** - This invention introduces a gear pump designed for pumping elastomeric materials. It features two meshing gears equipped with herringbone gear teeth. Each tooth has helical side portions and a curved central portion that extends circumferentially, allowing for continuous squeezing contact between the gears. This design ensures a uniform strip of elastomeric material is delivered from the gear pump.
2. **Extruder screw tip and associated flow channel** - This innovation pertains to a screw nose for a rubber extruder. The upstream portion of the screw increases in diameter, optimizing the engagement of rubber with the extruder barrel. Meanwhile, a downstream section tapers in diameter, facilitating engagement with a flow channel block. This design effectively reduces shrinkage and pressure drops at the discharge end, thereby preventing porosity and blisters in extruded rubber components.
