Abstract: Disclosed herein are a method and systems for cumene hydroperoxide cleavage with an improved configuration for online instrumentation. The systems comprise a first fluid loop comprising one or more reactors and a fluid pump and a second fluid loop in fluid communication with the first fluid loop. This second fluid loop comprises an instrument configured to measure a characteristic of a fluid flowing through the second loop, wherein an input of the second fluid loop is disposed downstream of said fluid pump and an output of the second fluid loop is disposed upstream of said fluid pump. The method comprises causing fluid to flow within a first stage comprising one or more reactors and a fluid pump, wherein the first stage is configured to decompose a cumene hydroperoxide in the presence of a catalyst mixture to form a dicumyl peroxide mixture. The method also comprises causing at least a portion of the fluid to flow through a instrumentation line in open fluid communication with the first stage.

Abstract: Apparatus for repairing out-of-round cores, upon which strapping material has been coiled, when the core and coiled strapping material assembly has been deformed and is therefore no longer capable of being mounted upon strapping unwinding and dispensing apparatus. The repair apparatus comprises a pair of diametrically opposed, substantially semi-circular shoes which are mounted upon a pair of diametrically aligned rod members that are operatively connected together by means of a diametrically oriented expansion member. The apparatus is adapted to be disposed internally within the deformed core and coiled strapping material assembly, and when the expansion member is diametrically extended, the pair of semi-circular shoes will be forced into contact with the inner periphery of the deformed core and coiled strapping material assembly thereby returning the same to a truly round configuration.
