Abstract: The present invention generally relates to methods and systems for mitigating trouble zones in a wellbore in a preferred pressure condition and completing the wellbore in the preferred pressure condition. In one aspect, a method of reinforcing a wellbore is provided. The method includes locating a valve member within the wellbore for opening and closing the wellbore. The method further includes establishing a preferred pressure condition within the wellbore and closing the valve member. The method also includes locating a tubular string having an expandable portion in the wellbore and opening the valve member. Additionally, the method includes moving the expandable portion through the opened valve member and expanding the expandable portion in the wellbore at a location below the valve member. In another aspect, a method of forming a wellbore is provided. In yet another aspect, a system for drilling a wellbore is provided.

Abstract: A container for pneumatically stirring a beverage. Current flow displaced from a flexible member, such as a depressible bulb, is regulated through an outlet optionally containing a one-way valve into an opening in a liquid receptacle. The resultant current flow in the receptacle initiates a stirring motion in the beverage. Air expelled from the depressible bulb may be replenished through an inlet in the bulb.

Abstract: Trucks which haul waste and fine, loose materials which are top loading through an open top need a cover to retain the material such as during travel. A full length cover, when raised for loading, may adversely affect the stability of the truck. An articulated cover includes a forward portion pivotally connected to the truck hauling body and a rearward portion pivotally connected to the forward portion. When the forward portion is raised the rearward portion folds downward against and parallel to the forward portion. This reduces the height of the raised cover to approximately one-half of the cover total length. Tie members are connected to the rear portion of the cover and to the hauling body and engage guide members on the cover to cause the rearward portion to unfold to an extended position when the forward portion is pivoted toward a closed position.
