Abstract: A connector system includes a first riser joint configured to form part of a riser. The first riser joint includes a pin. The connector system also includes a connector configured to couple to a wellhead assembly. The connector includes multiple collet segments that are configured to move radially-inwardly to engage the pin of the first riser joint.

Abstract: The invention provides a sock for the foot comprising a main body having a bottom portion that covers the bottom of the foot, a toe portion that covers the toes of the foot, and a heel portion that covers the heel of the foot. There is a strap that is sized to pass around the front portion of the ankle that has two opposing ends that attach to the main body.

Abstract: The valve operating apparatus cycles valves between open and closed positions. The valve operating apparatus includes a trailer for use in towing behind other vehicles, for instance, behind a pickup truck. The trailer includes an engine, pump, battery, reservoir and a bidirectionally oriented motor which is suspended from a telescoping extension bar. The operation of the valve operating apparatus is substantially balanced and requires very little effort by the operator to operate. Specifically, the operator does not have to push down or lift the apparatus as it is substantially balanced.

Abstract: A system and method for generating a parametric profile of an object to be modelled is shown which receives input from a user in the form of equations, generates further equations inherent to a profile definition, prioritizes the equations into ranked classes, sorts the prioritized equations to thereby create an ordered solved equation list, solves the sorted equations in the order they appear on the solved equation list and generates a profile of geometry entities constructed from the solutions of the solved equations. The system and method automatically constrain unknown variables within any under-populated equation sets based on heuristics and employ any redundant equations to determine and resolve conflicts among the equations to be used for generating the profile.
