A computer-implemented document management method is discussed. The method includes displaying in a messaging application a plurality of folders for storing electronic mail messages, analyzing content one or more of the electronic mail messages to locate identifiers associated with matters in a document management system, and generating a user-selectable object that, when selected, automatically causes the generation of a document management display for a user of the messaging application.
摘要:
Disclosed is a bimodal Ziegler-Natta catalyzed polyethylene, having a density of from 0.930 g/cc to 0.960 g/cc, and a molecular weight distribution of from 10 to 25, wherein an article formed therefrom has a PENT of at least 1500. Also disclosed is a method of preparing a tubular article including obtaining a bimodal polyethylene having a density of from 0.930 g/cc to 0.960 g/cc and a molecular weight distribution of from 10 to 25, and processing the polyethylene under conditions where a specific energy input (SEI) is less than 300 kW·h/ton, and wherein the article has a PENT of at least 1500. Further disclosed is a method for controlling the degradation of polyethylene including polymerizing ethylene monomer, recovering polyethylene, extruding the polyethylene, and controlling the degradation of polyethylene by measuring the SEI to the extruder and adjusting throughput and/or gear suction pressure keep SEI less than 300 kW·h/ton, and forming an article.
摘要:
An apparatus for engaging and moving a ram block. In some embodiments, the apparatus, or ram block changer, includes a support bracket coupled to a blowout preventer and an articulated arm releasably coupled to the ram block. The ram block changer may further include a pivot coupling assembly having a first axis of rotation. The pivot coupling assembly extends through the support bracket and the articulated arm, wherein the articulated arm is rotatable about the first axis of rotation relative to the support bracket. The articulated arm may include a first member receiving the pivot coupling assembly therethrough, a second member coupled to the ram block, and a second pivot coupling assembly having a second axis of rotation spaced apart from the first axis of rotation and extending through the first and second members. The second member is rotatable about the second axis of rotation relative to the first member.
