    摘要： This invention relates to apparatus for forming a fluid tight closure of an opening in a vessel. The apparatus includes a conduit or fitting adapted to be connected to the vessel, a plug insertable into the conduit and a means for locking the plug in the conduit to prevent the plug from moving out of the conduit. The locking means includes a locking element engageable with the plug to lock it in place. A connector located in a lateral bore through the conduit is connected at one end of the locking element and its other end has a threaded engagement with a nut also located in the lateral bore. Stops are provided at opposite ends of the nut so that upon rotation of the nut to move the connector and locking element between retracted and locking positions, the nut will alternately engage the stops. By making the distance between the stops greater than the length of the nut, the nut is free to move longitudinally between the stops and this construction avoids maintaining close manufacturing tolerances with respect to the distance between the stops. In a preferred embodiment, the inner stop is provided by a shoulder between an outer larger diameter portion of the bore and an inner smaller diameter portion. A seal is carried by the connector to seal between it and the smaller diameter portion of the bore as the connector is reciprocated by turning the nut. Normally the locking element will engage the conduit when in fully retracted position to limit makeup of the nut on the connector and hence limit the outward travel of the connector so as to maintain the seal within the smaller diameter portion of the bore. However, if excessive torque is applied to the nut so as to break the engagement of the connector with the locking element, means are provided to limit further makeup of the nut on the connector and the seal is located so as to remain within the smaller diameter portion of the bore when the nut has a maximum makeup on the connector and both have been displaced outwardly so the nut is in engagement with the outer stop. With this construction, the connector does not rotate thereby enabling it to have a simple bifurcated connection with the locking element and to carry a seal which merely slides along the bore in the conduit without rotation. The seal also isolates the threaded connection from fluids within the vessel.

    摘要： A device for facilitating the act of connecting a service line to a flowing main line. A gate type valve is rigidly attached to the main line and a barrel is removably affixed to the valve and is adapted to cooperate with a mandrel which includes a shaped charge at one extremity thereof. The mandrel cooperates with the barrel to enable the shaped charge to be positioned adjacent the main line, whereupon the explosive shaped charge perforates the main line when a detonator is activated. The mandrel is retrieved along with the barrel to enable further use of the device. The invention also comprehends a mandrel that can be affixed between the gate valve and the flowing main line by including a recoil device in conjunction therewith. The invention further includes a shaped charge that is adapted to be fabricated into the ball member of a ball type valve.

    摘要： A pipeline cleaning device comprising a body adapted to be moved forwardly through the pipeline, a plurality of springs mounted on the body, and a scraping element carried on each spring for engaging the inner wall of the pipeline in circumferentially spaced-apart relation. Each scraping element includes a base connected to the spring, a V-shaped blade upstanding from the base for tightly engaging the pipeline wall with its apex on the forward end thereof, and a relatively stiff rod extending from the base for tightly engaging at its outer end with the pipeline wall between the sides of the blade. Each of the base, blade, and rod is formed of urethane.
