Abstract: A hydraulic tool for working on a workpiece. A housing is configured for holding. A motor is positioned in the housing. A battery is supported by the housing and operable to supply power to the motor. A drive mechanism is supported by the housing and includes a cylinder, a piston moveably supported in the cylinder, and a pump powered by the motor and operable to supply hydraulic fluid to the cylinder to move the piston relative to the cylinder. A jaw member is supported by the housing and configured to engage with the workpiece. A spindle is operatively coupled to the drive mechanism such that operating the drive mechanism moves the spindle relative to the jaw member to work on the workpiece.

Abstract: A structural reinforcement for a hollow member comprising a rigid reinforcing member having a shape that substantially conforms to the cross section of the hollow member to be reinforced with an expandable adhesive material over at least a portion of the surface of the structural reinforcement having one or more extensions on its external surface which control and direct the direction in which the adhesive material expands to bond the reinforcing member to the internal surface of the hollow member, some of the extensions also provide improved reinforcement.
