    Abstract: Cleanout conduit valve assemblies for a cleanout conduit may include a vertically oriented valve housing. The valve housing may include a valve inlet end configured to be disposed in fluid communication with the cleanout conduit and a valve discharge end opposite to and generally above the valve inlet end. The valve discharge end may be oriented within a valve discharge plane disposed at a discharge angle of greater than 0 degrees with respect to a horizontal plane. The valve discharge end may have an upper discharge opening side and a lower discharge opening side sloped downwardly from the upper discharge opening side. A valve body may be pivotally carried by the valve housing at the upper discharge opening side of the valve discharge end. Methods of preventing precipitation and runoff on a ground surface from entering a cleanout conduit connected to a sewer service line are also disclosed.

  • Patent number: 9700627
    Abstract: Poly(?-amino esters) prepared from the conjugate addition of bis(secondary amines) or primary amines to a bis(acrylate ester) are described. Methods of preparing these polymers from commercially available starting materials are also provided. These tertiary amine-containing polymers are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the poly(amine) nature of these polymers, they are particularly suited for the delivery of polynucleotides. Nanoparticles containing polymer/polynucleotide complexes have been prepared. The inventive polymers may also be used to encapsulate other agents to be delivered. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings.
