Abstract: Confirming user consent includes prompting the user to tap a card a card reader or a computing device and confirming consent in response to the user taping the card. The user may be prompted for a response in a plurality of possible responses and only a particular one of the possible responses may require taping the card. The user may consent to installation of software on the computing device. The user may be logged in to the computing device. A login ID for the user may be cached and/or may be accessed in connection with the user tapping the card. Confirming user consent may also include obtaining a pairing code for accessing the card and confirming consent in response to the user taping the card and the pairing code allowing access to the card. The pairing code may be cached in the card reader or the computing device.

Abstract: Continuous mixers of plastic materials are equipped with greased journal bearing assemblies instead of bulky, expensive, pumped circulating-oil lubricating systems, usually involving oil-cooling heat exchangers with circulating water. Such pumped oil systems having traditionally been employed in the past for lubricating journal bearings of the two rotors in such mixers. Novel thermal isolation of the journals for the two rotors separates their bearing assemblies from the severe heat being generated during mixing of plastic materials by continuous rotation of the two rotors within the mixer barrel. Localized cooling provides heat sinks for the drive and driven journals of each rotor. The rotors are shown as three-piece assemblies with drive and driven journals separate from the main rotor body.
