  • Patent number: 11287074
    Abstract: A device for repairing pipe leakage takes the form of a short section of PVC pipe with fittings. The pipe is ideally a 1?-2? section fashioned into a U-bend with a substantially semi-circular bend and two arms, and the fittings take the form of an elbow joint glued onto each arm. The arms are ideally offset up to 5° from parallel. A method of repairing cracked PVC piping using the device involves cutting out a 4?-6? section of piping, gluing the exposed ends of the broken piping as well as the elbow joints, squeezing the U-bend, positioning the squeezed device into the gap in broken piping, and releasing the U-bend to fit the elbow joints over the exposed ends of broken piping. The device has no vulnerable moving parts or O-rings, and it obviates the need to remove entire pipes.

  • Patent number: 10054559
    Abstract: A compact, pressure conserving, steam quality and flow rate measurement system is described. Embodiments of the system can include a steam quality measuring device having a converging/diverging nozzle and a conditioning orifice plate. The steam quality measuring device can be adapted to measure flow conditions of a two-phase steam to determine steam quality. The converging/diverging nozzle can be implemented to reduce pressure loss and control flow rate. The conditioning orifice plate can be implemented to reduce flow conditioning pipe lengths and eliminate secondary flow conditioning elements. By placing the two flow elements in series, data from the flow elements can allow for a simultaneous solution of flow equations yielding a measurement for steam quality.

  • Patent number: 9857077
    Abstract: A head assembly for a pulverized coal nozzle includes removeable wear-resistant inserts having vanes. The vanes may be flat or curved to direct a stream of air and pulverized solid fuel particles from the inlet port toward the outlet port. The curved vanes curve in two dimensions to evenly distribute the stream of air and pulverized solid fuel away from the outer surfaces reducing wear and corrosion. The pipe elbow has a removable cover that allows for easy access. The vanes are attached to a wear-resistant replaceable liner thus allowing them to be easily removed and replaced. The wear-resistant liner may be made from several parts for ease of removal and replacement.
