Exercise weight structure
11110672 · 2021-09-07 · ·

A method of producing an exercise weight structure comprises mixing a particulate material with a binder material and molding the resulting mixture to an appropriate shape. An outer skin for the exercise weight structure is firstly formed of a resilient material, and forms a mold into which an inner weight section or body is molded or cast. The inner weight section and the outer skin are both formed of recycled material and include a common binder material.

20210260792 · 2021-08-26 ·

A process for preparing a composite part, the process comprising: recovering unsaturated resin prepreg scrap; combining the recovered unsaturated resin prepreg scrap with a second resinous thermosetting component; and co-molding the prepreg scrap and resinous thermosetting component together under a pressure of 25 to 4000 psi and at a temperature of 100-400° F.

METHODS FOR MANUFACTURING BULKED CONTINUOUS FILAMENT FROM RECYCLED PET
20210299914 · 2021-09-30 ·

A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.

Reactor for continuously treating polymeric material

A system for continuously treating recycled polymeric material includes a hopper configured to feed the recycled polymeric material into the system. An extruder can turn the recycled polymeric material in a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. The molten material is depolymerized in a reactor. In some embodiments, a catalyst is used to aid in depolymerizing the material. In certain embodiments, the catalyst is contained in a permeable container. The depolymerized molten material can then be cooled via a heat exchanger. In some embodiments, multiple reactors are used. In certain embodiments, these reactors are connected in series. In some embodiments, the reactor(s) contain removable static mixer(s) and/or removable annular inserts.
