Abstract: An improved magnetic mixer includes an agitator that includes a plurality of agitator magnets. A bearing arrangement allows the agitator to be magnetically levitated along the outer surface of a cylindrical vessel fitting located within a mixing vessel. The same magnetic force that is used to levitate the mixer drives the agitator. The magnetic force is preferably generated by a plurality of magnets which rotate within an aperture extending into the vessel fitting. By magnetically levitating the agitator, there is no thrust generated by the agitator against the vessel fitting which eliminates the need for thrust bearings and reduces the overall frictional forces. The low friction results in reduced particle generation, reduced power consumption and reduced maintenance compared to conventional magnetic mixers.

Abstract: An anchor connector incorporating a flexible joint (16) for securing the tension legs (14) of a tensioned leg platform. A latch dog head (34) engages a first recess (26) on the fixed member (22) of the flexible joint and a template recess (30) to prevent disconnection when the dog heads (34) and latch carrier (40) are in a lower position. With the latch carrier (40) in an upper position the latch dog heads (34) fit within a second recess (44) in the fixed member with the dog heads claring shoulder (32) of template recess (30), whereby the connector may be released.
