Abstract: A material handling and mold filling system is provided which directs the flow of molten plastic material from an extruder and allocates the molten material to a plurality of nozzles through the use of independently operated, variable valves. The system therefore provides independent streams of molten plastic material having variable temperatures and flow rates or volumes to particular sections or regions of the mold. This independent temperature or flow of molten plastic material facilitates the complete, rapid and accurate filling of the molds, reducing turbulence and other temperature or flow-related imperfections in the finished components. A multiphase material handling system is also disclosed for expeditious sequential and simultaneous filling and pressing of the mold and extracting the completed component from the system.

Abstract: A modular flooring system is disclosed which is designed to support heavy loads while providing stability and ground protection. The invention contemplates a modular mat having an integral main body with offset mounting and assembly flanges and a lattice interior. The mat is constructed from a unitary piece of high strength plastic. Each flange edge contains an outward radiused edge, while each non-flange edge contains an inward radiused edge. Each flange engages with a corresponding flange on an adjacent tile, allowing the outward radiused and inward radiused edges to properly mate. One or more metal cam locks located along the upper flange edges are secured into corresponding cam receptacles located along the lower flange edge. The mats may utilize optional top covers to prevent water and debris from entering the mats. The modular flooring system provides increased strength and stability and protection of the subsurface in heavy industrial applications.

Abstract: A modular flooring system is disclosed which is designed to support heavy loads while providing stability and ground protection. The invention contemplates a modular tile with fully integrated connector loops, receiver pins and optional metal cam locks located in the corners of the floor tile or along the tile edges. The tiles contain an overlap edge, which engages with an underlay edge on an adjacent tile. This arrangement allows the tiles to overlap at an angle other than 90 degrees, providing greater strength at the point where adjacent tiles meet. The underlay edge contains a liquid capture channel which traps liquids which may seep between the adjacent tiles. The tiles are also provided with longitudinal recesses which extend through the top and bottom surfaces to the surface below, allowing for ventilation that is critical for grass and turf surfaces. The modular flooring system provides increased strength and stability and protection of the subsurface.
