Latest Patents

One of Benjamin's latest patents is for a multiple screw extruder implemented with a vacuum vent and screws configured to densify or extract fluid from material processed by the extruder. This innovative design combines the application of vacuum to a strategically positioned vacuum vent with specially configured extruder screws. The technology allows for the extraction of gases, primarily air, from the extruder, thereby densifying the materials introduced and removing unwanted fluids from mixtures with molten polymeric materials. This extruder is versatile, capable of performing material densification and fluid extraction either separately or simultaneously. The implementation of this vacuum feed technology significantly increases the rate of extrudate throughput compared to conventional atmospheric venting methods.

Another significant patent by Benjamin is the extruder screw shaft alignment apparatus and method. This invention features puck and collar alignment device embodiments that facilitate the simultaneous insertion of screw shafts into drive couplings. The alignment keys correct deviations in alignment and rotation, ensuring that the screw shafts fit properly within the extruder's barrel. The design includes tapered front and side faces that incrementally adjust both coaxial alignment and rotational position, allowing for precise and efficient assembly.
