Abstract: A jack assembly comprises a cylinder defining an interior, a piston having a piston head slideably engaged with the interior of the cylinder, an extension chamber defined between the piston head and the interior, and a pressure relief assembly integrated proximate the piston head and defining a relief passageway in selective fluid communication with the extension chamber. When a fluid pressure in the extension chamber exceeds a certain level, the pressure relief assembly allows fluid to flow through the relief passageway. In one form, the pressure relief assembly comprises a valve body, a relief passageway defined within the valve body, a valve seat formed along the relief passageway, a plug configured to selectively engage the valve seat, an adjustment member moveable along the relief passageway, and a biasing member captured between the plug and the adjustment member to urge the plug toward the valve seat.

Abstract: A rotary air motor driven hydraulic pump has separate pressure and return actuators and first and second stage eccentric driven pistons 180 degrees out of phase and driven by the motor through a gear reduction unit. The pressure and return actuators are on/off/proportional valves and the pump has two pressure relief valves with one adjustable from outside of the pump for a user to set a pressure limit of the pump. Above a certain output pressure limit, a bypass valve shunts flow in excess of that needed to precharge the second stage compression chamber from the first stage piston to an elastic reservoir from which the hydraulic fluid pumped by the pump is drawn. To make the pump stall at a certain output pressure, a pressure limiting valve can be used that cuts off the air supply to the pump at the desired output pressure.

A pilot-operated device is included that is configured to selectively drive the tool with pressure from at least one of the output of the low-pressure pump and the output of the high-pressure pump. The pilot-operated device receives pilot pressure from the output of the low-pressure pump to control selectively driving the tool with the output of the two stage pump.

In addition circuitry, responsive to user input, selects a non-real-time display program to execute under the control of the general purpose operating system from among a plurality of available non-real-time display programs.

Abstract: A bather cable anchor rail assembly is disclosed. The assembly is adapted to be encapsulated in a concrete column and engage a plurality of cables to provide a barrier between successive columns of concrete. The assembly includes a first rail member and a plurality of threaded connectors. The threaded connectors are adapted to be engaged by a chuck that includes cable grippers adapted to engage one of the cables. The threaded connectors can be attached to the first rail member in the same orientation with a predetermined spacing between the central axis of the plurality of threaded connectors.

Abstract: A high pressure metering valve has a valve element with a closing portion, a metering portion and a rapid return portion. The closing portion seats against a corner seat at the end of a valve bore in which the metering portion has a close sliding fit. When the element is unseated, a flow rate can be metered depending on the overlapping length of the metering portion in the valve bore. At the opposite end of the metering portion, the rapid return portion is undercut to be of smaller area than the metering portion to provide a full open state for rapid fluid return.
