Abstract

A system and process for converting plastics and other heavy hydrocarbon solids into retail petroleum products are provided. The plastics are processed by melting, pyrolysis, vapourization, and selective condensation, whereby final in-spec petroleum products are produced. The system provides a reactor for subjecting the plastics to pyrolysis and cracking hydrocarbons in the plastics to produce a plastics vapour comprising hydrocarbon substituents; one or more separation vessels for separating the plastics vapour into hydrocarbon substitutents based on boiling points of the hydrocarbon substituents; one or more condensers for condensing the hydrocarbon substituents into one or more petroleum products; and means for collecting the one or more petroleum products. Fuels generated during the process can be recycled for use upstream in the process.

Abstract

A system for reading a magnetic tape is provided. The system comprises a magnetoresistive head, a tape controller, an analog-to-digital converter and a processing unit. The tape transport controller controls a movement of a magnetic tape with respect to the magnetoresistive head. The analog-to-digital converter generates a signal upon receiving an analog signal read by the magnetoresistive head on the magnetic tape. The processing unit identifies a magnetic flux transition in the signal to detect a bit from the signal from the signal based on the identified magnetic flux transition. Identification of the magnetic flux transition in the signal includes analyzing voltage wave forms of the signal. A method and a computer readable storage medium for reading a magnetic tape are also disclosed.

• G11B 15/02 - Control of operating function, e.g. switching from recording to reproducing
• G11B 5/627 - Record carriers characterised by the selection of the material of leaders for magnetic tapes, e.g. non-magnetic strips on the tapes or for connection
