Patent number: 9010473Abstract: A motorized retractable step apparatus includes one or more steps that move between a retracted position and a deployed position. The step apparatus includes a drive member that spans the length of the step apparatus and rotates to retract or deploy the steps. The step apparatus uses a direct drive configuration to transfer power from an electric motor to the drive member. The step apparatus can also includes a brake coupled to the electric motor and/or extruded aluminum steps. These features simplify construction of the step apparatus and make it more reliable than conventional motorized steps.Type: GrantFiled: October 3, 2013Date of Patent: April 21, 2015Assignee: Lippert Components, Inc.Inventors: Aaron Rasmussen, Chad Johnson, Stephen W.

Patent number: 8424605Abstract: A casing string is augmented with one or more variable flow resistance devices or “vibrating tools” to facilitate advancement of the casing and distribution of the cement in the annulus once the casing is properly positioned. The method includes vibrating the casing string while advancing the casing down the wellbore or while the cement is pumped into the annulus, or both. After the cementing operation is completed, the devices may be drilled out to open the casing string for further operations. The casing string assembly may include a vibrating tool at the end in place of a conventional float shoe or float collar. Multiple vibrating tools can be employed in the casing string, and they may be combined with conventional float shoes and collars. Additionally, vibrating tools in the form of plugs can be pumped down and landed inside the casing string.Type: GrantFiled: April 25, 2012Date of Patent: April 23, 2013Assignee: Thru Tubing Solutions, Inc.Inventors: Roger L.
