Abstract: An aqueous urea dosing system has a first tube through which the urea solution is conveyed to a small mixing chamber. Compressed air is continuously conveyed through an annular space between the outer surface of the first tube and the inner surface of a second tube which has a distal end that extends beyond a distal end of the first tube. The mixing chamber is positioned between the respective distal ends of the first and second tubes. The urea solution is discharged into the small mixing chamber, and subsequently immediately into an exhaust gas, in a series of discreet pulses, the width and period of which are controlled by a pulse-width-modulated flow control valve spaced from the exhaust gas.

Abstract: A semi-permanent reference electrode for use in monitoring and measuring metals in field applications, such as cathodic protection. This electrode has an outer electrode body with a cap and porous plug. The outer electrode body is filled with a fill solution which is a saturated salt solution formed from a solid salt. The solid salt is hygroscopic with a low deliquescence point. An opening is provided in the cap to allow moisture into the outer electrode body to combine with the fill solution to maintain the saturated salt solution in the field. This saturated salt solution must maintain a constant pH for use in the semi-permanent reference electrode. A wire is used within the outer electrode body which connects to a voltmeter. This voltmeter measures the potential difference between the reference electrode and the field component of interest, which can include pipelines, storage tanks and bridges.

Abstract: A method and system for containing escaping hydrocarbon fluid from a well pipe of a production well. Suppression of the hydrocarbon fluid to a level below the breach location using a control fluid allows the breach to be repaired through the installation of a containment sleeve at the location of the breach. After collecting the escaping hydrocarbon fluids with a containment sleeve, the hydrocarbon fluid is routed to a collection reservoir from which it may be easily recovered without causing environmental damage. This process occurs with minimal downtime of the production well with the added environmental benefit of remediation of earth contaminated by the hydrocarbon breach.

Abstract: A cemented open hole selective fracing system is shown. In the producing zone, an open hole is drilled therein and a production tubing is cemented in place. At preselected locations along the production tubing, the production tubing will have sliding valves located there along. The sliding valves may be selectively opened by a shifting tool, and the cement around the sliding valve dissolved. Thereafter, the formation may be fraced immediately adjacent the opened sliding valve. By selectively opening different combinations of sliding valves, fracing can occur in stages with more fracing pressure and more fracing fluid being delivered deeper into the formation. Just as the sliding valves can be selectively opened with a switching tool, the sliding valves can also be selectively closed to protect the production of the well.

Abstract: Manual braking system with a variable braking force for a wheelchair. Caliper type brakes positioned to mount on and exert braking force on disks mounted to interior “disk” hubs rotatably mounted to the wheelchair frame wheel hubs are mated with the “disk” hubs with a push button release pin allowing the wheel to be quickly removed without disturbing disk braking system. Caliper brakes are actuated by a manual lever arm, cable and pulley combination mounted to the frame of the wheelchair. The lever is provided with and without a plunger mechanism. A plunger mechanism allows the user to maintain the manual braking force exerted on lever without hands. The plunger mechanism is fixably mounted and positioned to insert a plunger head into notches on the lever. The force exerted by the plunger head is sufficient to hold the plunger head within the notch and prevent movement of the lever without manual force.
