  • Patent number: 9810613
    Abstract: Systems and methods are described for monitoring displacement on structural elements of subsea systems such as on components of a subsea pipeline network used to transport production fluid from a subsurface wellhead to surface facilities. The described techniques sense changes in displacement using a sensing blade, for example made of crystalline material such as sapphire, that is anchored to the structural element such that it is approximately perpendicular to the direction of sensed displacement. Displacement is sensed as bending of the sensing blade using one or more instruments fabricated on the blade. Robustness of design is in part provided by additional flexible non-sensing blades mounted in parallel to the sensing blade.

    Abstract: A firing-operation totalizing device for a gas nail gun includes two pressure areas, a pressure feedback unit mounted in a body, and an electric control unit. The pressure areas are constituted by an interior of a combustion chamber and an interior of a cylinder body. The pressure feedback unit outputs a pressure signal in response to each pressure change of at least one of the pressure areas. The electric control unit includes a control circuit that totalizes the number of the firing operations based on the pressure signals received thereby. As such, the totalized number of the firing operations is increased only when a pressure change of the at least one of the pressure areas occurs due to an explosion to totalize accurately the number of effective firing operations.

  • Patent number: 8397968
    Abstract: A setting tool arrangement includes a stock of a setting tool having one or more sleeve stops. A barrel of a setting tool is slidably receivable in the stock. A sleeve is interactive with the barrel to move to a position allowing the barrel to move when pointed in a direction opposite the direction of gravity and to a position of interference with the one or more sleeve stops thus preventing the barrel from moving when pointed in a direction approximating the direction of gravity.

  • Publication number: 20130008936
    Abstract: A position-limiting device forms a portion of a magazine assembly of a powder-actuated fastener-driving gun, and includes a nail-guiding pipe and a clamping unit. The nail-guiding pipe extends through a sleeve of a magazine assembly such that an end of the nail-guiding pipe is disposed outwardly of the sleeve. The nail-guiding pipe includes a tubular body, a nail passage hole formed in the tubular body and in spatial communication with the nail-receiving space in the magazine housing so as to allow one of the nails to be moved from the magazine housing into the nail-guiding pipe therethrough, and two aligned apertures formed respectively in two opposite sides of the tubular body. The clamping unit is disposed on the nail-guiding pipe, and extends through the apertures for clamping the one of the nails disposed within the nail-guiding pipe.

  • Patent number: 8302832
    Abstract: A fastener driving tool includes a power source including a cylinder, a piston with a driver blade reciprocating in the cylinder, a tool nose associated with the power source for receiving the driver blade for driving fasteners fed into the nose, and a magazine housing a supply of the fasteners. A magazine feeder mechanism is associated with the magazine for sequentially feeding fasteners into the nose, and the feeder mechanism includes a reciprocating feed piston. A conduit is connected between a port in the cylinder and the feed mechanism for diverting combusted gas for activating the feed piston. The port is disposed in the cylinder a specified distance below a piston prefiring position, and the distance is reflective of a delay of feeding the gas to the feed piston at least until engagement between an end of the driver blade and a head of a fastener in the tool nose.
