摘要： An improved surgical stapling instrument is provided for applying surgical staples to human tissue. The instrument has an articulated stapling head assembly mounted by a rotatable and flexible support shaft on an actuator handle assembly with an improved actuator mechanism for closing and firing the stapling head assembly. The stapling head assembly comprises a fixed jaw with a staple cartridge and a movable jaw with an anvil for clamping the tissue therebetween. The actuator mechanism comprises a jaw closure lever for closing the jaws and a staple firing lever for actuating a staple driver to drive the staples from the staple cartridge into the tissue and against the anvil. The actuator mechanism also includes a cam pulley mounted for rotation by the staple firing lever and secured to a firing cable for actuating the staple driver. A set of drive gears rotatably positioned on opposite sides of the cam pulley mesh with gear sectors on the staple firing lever to rotate the cam pulley and apply tension to the firing cable when the staple firing lever is actuated. The cam pulley has a contoured cam lobe for actuating the firing cable with different mechanical advantages as the pulley is rotated. An anti-backup member engages the cam pulley to prevent the pay-out of the firing cable before and after the staple firing lever is actuated. The length of the support shaft can be adjusted to set the tension in the closure cable so that the jaws are completely closed by the jaw closure lever to produce staples of uniform height when the staple firing lever is actuated.

摘要： A below grade, spill containment device for connection with the riser pipe of an underground fuel storage tank. The containment device is disposed within and isolated from a manhole, which is mounted in a concrete apron. The containment device comprises a compositely formed container, rigidly mounted on the riser pipe. The container formed of structural synthetic resin material elements held in assembled relation by snap fitted lugs and notches. A lid, for closing the upper, access opening, is mounted on a pivotable arm. A lever pivoted on the arm selectively engage latch means to lock the lid in a closed position. A projection on the lever prevents the manhole cover from seating if the lever is not in its lock position. A valve for draining fuel from the container to the riser pipe is closed when the lid is open and opened when the lid is closed. The manhole and the containment device are packaged in a shipping carton in spaced relation be corrugated paper sheets. These sheets are employed in obtaining a desired relation between the containment device and manhole in the installation of these components, which involve pouring a concrete apron around the upper end of the manhole. An alternative system employs adjusting nuts to obtain this relationship between the manhole and containment device. In one embodiment the manhole is compositely formed to permit relative movement between its upper and lower portions, after installation.

摘要： A vapor recovery nozzle is disclosed in which the main body of the nozzle has the vapor passage located above the fluid passage, so that the fluid valve is separated from the top of the nozzle by the vapor passage. Thus the valve may only be removed through the bottom of the nozzle by removing the trigger mechanism and removing the vacuum tripping mechanism which is also connected to the trigger mechanism. Removal of the tripping mechanism is also made easily determinable by the use of a soft aluminum seal over the top opening of the trigger mechanism. The tripping mechanism is responsive to displacement of the vapor recovery shroud to prevent dispensing fuel unless the nozzle is in the fill tank. Other improvements to prior art vapor recovery nozzles include an improved trigger mechanism having a camming surface to engage the stem of the main valve.

摘要： An automatic overfill prevention system for gravity filling of an underground liquid storage tank from a tank truck fill line provides a venturi in the fill line creating a partial vacuum which is vented from the liquid storage tank through a vent line until the liquid in the storage tank rises to a predetermined level to submerge one end of the vent line and trigger a latching means to close the fill line. The assembly also includes a containment manhole to hold any inadvertent spillage occurring during the filling process.

摘要： A float chamber located in generally parallel, laterally spaced relationship to the main liquid flow passageway contains superimposed floats that move along a substantially linear path of travel. The floats cooperate with other control components to effect closure of a main valve assembly when the liquid level adjacent the mechanism reaches a preselected first elevation, and to close a bleed valve assembly when the liquid level reaches a second, higher elevation. The main valve assembly includes a movable plate valve that is spring biased toward an open position and that is biased toward a closed position by the force of liquid adjacent thereto and upstream therefrom. A latch and associated catch prevent movement of the valve plate to its closed position until such time as the liquid level reaches the first elevation.

摘要： A containment manhole is formed of an upper rim and a bottom sump portion connected by an expansion joint permitting radial and axial movement of the sump portion relative to the rim. The sump portion has an integrally formed drain for the drainage of spilled product in the manhole directly into the riser. The rim also has an upstanding flange and the lid of the manhole extends over the flange with a wide, downwardly sloped skirt directing water off the lid to the outer perimeter.
