Abstract: A packet-filtering network appliance such as a threat intelligence gateway (TIG) protects TCP/IP networks from Internet threats by enforcing certain policies on in-transit packets that are crossing network boundaries. The policies are composed of packet filtering rules derived from cyber threat intelligence (CTI). Logs of rule-matching packets and their associated flows are sent to cyberanalysis applications located at security operations centers (SOCs) and operated by cyberanalysts. Some cyber threats/attacks, or incidents, are composed of many different flows occurring at a very high rate, which generates a flood of logs that may overwhelm computer, storage, network, and cyberanalysis resources, thereby compromising cyber defenses.

Abstract: An injection molding machine includes complementary mold members which cooperate to present a mold cavity in the shape of a clay pigeon or other articles. An injection passage leading to the mold cavity receives a slidable pin of smaller diameter than the passage. The pin has a tapered tip which, when the pin is extended by a power cylinder, seats in an outlet opening of the passage to block the opening in a manner to prevent the formation of a sprue on the part. The pin is heated along with a surrounding sleeve to maintain the material in the passage in a molten state and to assure proper release of the part from the mold. When the pin is retracted, molding material is able to flow around it, through the injection passage, and into the mold cavity.
