IPC: C10G1/10
Filed: 2017-06-20
Abstract: A Heated Airlock Feeder is disclosed. Heated Airlock Feeder allows for the continuous feeding of solid, shredded plastic into a reactor tube surrounded by clamshell burner boxes. Inside of the reactor tube, two augers, one with right hand flights and one with left hand flights are welded to smooth augers to create two continuous augers that push solid plastic material, liquid plastic material and molten plastic material through two small holes. As the plastic is in its molten state while being forced through the two small holes, an airlock is formed preventing air form entering the system. As the solid, shredded plastic is fed into the system, an airlock is formed allowing for the continuous feeding of the system. The clamshell burner boxes allow for convection and radiant heat allowing for even, continuous heat.

Abstract: The technology is generally directed towards real-time power grid island detection and monitoring, including obtaining and outputting information about the cause and location of the islanding event, island size, island composition, phasor measurement units in each island, and the overall island frequency. The technology provides for suggested island resynchronization actions such as one or more circuit breakers (706A, 706B) that can be closed by the power grid system operators to resynchronize an island(702A, 702B) with the main island system(704). An application program may output the information and also assist the operators during the resynchronization process by providing real time information about the voltage difference and frequency difference across each proposed circuit breaker in the suggested restoration point. Real-time tracking of the island resynchronization actions is also described.
