Abstract: Apparatus and method for overhauling a flanged coupling of joined conduit components including a gripping mechanism that straddles the flange-coupling and grips both flange-coupled components. The gripping mechanism is mounted on a lifting frame and bears the loadings upon the gripped tubular components during a moving operation. The apparatus also includes a collar sized to fit over the flange-coupling and located in spaced apart cradles supported on a base frame. The cradles are configured to receive the flange-coupled tubular components and position the collar for closure about the flange-coupling. The collar is provided with fasteners for closure of the collar about the flange-coupling, and a fastening mechanism operating the fasteners to secure the collar when closed about the flange-coupling.

Abstract: Apparatus and method for handling a fluid-tight flange coupling between a first and a second conduit component while maintaining the fluid integrity of the coupling. The apparatus includes a gripping mechanism configured to straddle the flange coupling and grip both of the first and second conduit components. The gripping mechanism is mounted on a lifting frame able to bear the loadings upon the gripped components during a moving operation. The apparatus includes a base frame with a gripping mechanism to receive the flange coupling. The coupled components are gripped on each side of the flange coupling to maintain the fluid integrity of the flange coupling.

Abstract: A chip select circuit is based on a multiplexed bus having a chip select phase, an address phase, and a data phase. During the chip select phase, a chip select latch receives chip select signals from the multiplexed bus at one input and a chip select enable signal at a second input. The chip select latch has a plurality of outputs to the chip select inputs of a plurality of connected devices. Based on the chip select signals from the multiplexed bus, one of the plurality of outputs enables a selected connected device. During the address phase, an address latch receives address signals from the multiplexed bus at a first input and an address enable signal at a second inputs. The output of the address latch passes the address signals to the address inputs of the plurality of connected devices. The chip select circuit is operative to used the multiplexed bus to select one of the connected devices using the single chip select enable signal without requiring further enabling/control signals.
