Abstract: A system and a method provide a coating on an interior surface of a tire. A valve connects to the interior of the tire. The method connects a source of coating material to the valve, propels the coating material through the valve, and applies the coating material to the interior of the tire. The system has a source of a coating material connected to the valve. A propellant causes delivery of the coating material through the valve into the tire. Another method coats an interior of a tire mounted on a rim. The method connects a first end of a tube to a source of coating material and inserts the second end of the tube into the interior of the tire encircling the rim. The coating material moves through the tube into the tire. The tube is withdrawn from the tire moving along the interior circumference of the tire.

Abstract: The present invention provides a valve that controls a flow of gas or solid objects through a pipe, and particularly a z-valve used in an elevated rail transportation system. The valve includes vanes hinged to a valve stem that fold into a z-shape and retract into the valve body when the valve is open. A valve cap positioned at the top of the valve stem matches the contour of the inner surface of the pipe, allowing unobstructed flow. When the valve is closed, the valve stem is elevated into the interior of the pipe and the valve cap rotates 90° to match the contour at the top, providing a seal. The vanes extend from the z-shape to completely block a cross-section of the pipe, stopping the flow. The flow may be modulated by varying the extension of the vanes to allow a portion of the flow to pass the valve.

Abstract: The invention is an improved conduit flow controller for selectively controlling the flow of fluid through an elongated conduit. The conduit has an aperture defined by a continuous peripheral edge in the sidewall of the conduit. An elongated housing surrounds the aperture and is sealingly connected to the conduit. A conduit stopper is movably mounted in the housing and is positionable in the conduit. The conduit stopper includes a deformable sealing element having opposed flat sides and an edge engageable with the conduit. A carrier is sealingly connected with the sealing element. A resilient seal is mounted on a carrier and is engageable with the continuous edge. The sealing element is cooperative with the seal to close a portion of the conduit to regulate the flow of fluid along the elongated conduit.

Abstract: After removal of a valve cap from an in line shut off valve the Retaining Snap Ring Adapter with male threads and seat at one end, female threads and seat at the other end, a hex outer surface at the female threaded end, a longitudinal passageway down its center, is designed to be permanently installed on an in line shut off valve having a threaded moveable plug (operator) and said Adapter will not interfere with the moveable operator which opens and closes the valve when turned by a hexagonal wrench. The Retaining Ring Adapter prevents an improperly back seated operator from being ejected as a deadly missile by the normal operating pressures.The Retaining Snap Ring Adapter having been permanently installed on the valve, the cap is returned to the valve but is now screwed onto the added Retaining Snap Ring Adapter which is essentially now part of the valve.

Abstract: The primary component of the apparatus is a full port ball valve. One port of the valve is adapted to attach to the bonnet threads of a stop valve. A tubular chamber is attached to the other port of the ball valve with the axes of the ball valve body and chamber aligned with the axis of the stop valve. A cylindrical probe fits through the chamber and open ball valve with a seal between the probe and the free end of the chamber. The inserted end of the probe is adapted to engage splines on a valve stem assembly of a stop valve. A rod extends through the probe and seals prevent leakage through the probe around the rod. The inserted end of the rod is adapted to engage the threads in the end of the stop valve stem assembly. Once the probe and rod are inserted and the splines and threads in the stop valve stem assembly are engaged, the probe is rotated to remove the stem assembly from the stop valve. The probe is then retracted so that the stem is in the chamber and the ball valve is closed.

Abstract: A concentrically multi-shafted apparatus compresses a compressible stopper to effect a seal in a through-hole of a main utility line to permit a substantially leak-free removal and replacement of a service saddle or a service seal. Counter rotation of concentric shafts, depending upon the direction of rotation, increases or decreases an axial load on the compressible stopper. The external concentric shaft is in sealing engagement with a housing which, when coupled to a utility customer's gate valve permits a main line through-hole to be sealed by the compressible stopper without leakage of water or gas. Once the through-hole is sealed, the service saddle can easily be removed and replaced.

In order to make it possible to use the tool (30) for handling plugs (17) having cavities (18) of considerable varying diameter, the gripping portions (38) of the gripping jaws (37) are arranged to be moved from rectracted inner end positions to expanded outer end positions through the action of spring forces applied from a spring (45) contained in the plug holder (34 ).

Abstract: Apparatus and method for tapping a tubular member includes a split ring type clamp arrangement having a tapping tee assembly extending therefrom. The clamp arrangement includes a combination alignment/hold structure to facilitate orientation of the clamp arrangement with the tubular member. A combination valve and cutting tool cooperates with the tapping tee assembly. An annular cutting surface on the tool has a first diameter for cutting an aperture in the tubular member. An annular, conical flange portion on the exterior of the tool spreads the aperture to a diameter greater than the first diameter, while a sealing land on the cutting tool has a second diameter larger than the first diameter and is adapted for close receipt in the aperture. A radial shoulder engages an internal surface of the tubular member for securely clamping and sealing the tapping tee assembly thereto.

Abstract: This process permits an inlet/outlet to be established in a liquid filled tank using an underwater diver without the necessity of draining or otherwise putting the tank out of service. The diver enters the tank at the top and places a dry pot against about the center of the back of the manhole cover. A hole is drilled in the manhole cover and a pipe nipple inserted through the hole. A flange is provided on the pipe nipple and if a gasket is not used, it is welded completely around to prevent leakage. A cap or valve is screwed onto the pipe nipple on the outside and the dry pot is removed. Various other ways of placing the pipe nipple through the wall are described. The installed nipple can be used by attaching a suction hose thereto for the purpose of removing sediments from the floor of the tank. If desired a smaller inlet/outlet installed in this manner is used to supply air for a diver working on the inside of the tank.
