Abstract: The present disclosure includes a radiological material detector having a convertor material that emits one or more photons in response to a capture of a neutron emitted by a radiological material; a photon detector arranged around the convertor material and that produces an electrical signal in response to a receipt of a photon; and a processor connected to the photon detector, the processor configured to determine the presence of a radiological material in response to a predetermined signature of the electrical signal produced at the photon detector. One or more detectors described herein can be integrated into a detection system that is suited for use in port monitoring, treaty compliance, and radiological material management activities.

Abstract: A compression molding process incorporates a reciprocating screw plasticator to reduce or eliminate problems associated with variations in the amount of time that a thermoplastic material is maintained in a plasticated state. The process includes providing a thermally controlled mold having a first section and a second section which together define a mold cavity, plasticating thermoplastic material in a reciprocating screw extruder, depositing a mass of plasticated thermoplastic material from a nozzle at the discharge end of the plasticator onto one of the sections of the mold, closing the mold sections together to shape the plasticated mass of material, cooling the thermoplastic material in the mold cavity to solidify a thermoplastic article, and removing the shaped article from the mold.
