  • Patent number: 9914654
    Abstract: In the drinking water industry, pilot plants have played a big role in assisting water professionals, utilities, and engineering firms in generating information about the behavior of large full scale systems. Due to the identification of new contaminants, stringent regulations, and demand for improved water quality the demand for novel water treatment challenges across North America have significantly increased. A portable evaluation pilot skid (PEPS) accommodates all water qualities. A vent valve screen is mounted inside the contactor with holes large enough to prevent clogging. Air is introduced into the contactor prior to the screen. The screen is mounted such that it breaks the air into small bubbles creating the effect of a stone diffusor. Air flow is easily adjusted with a needle valve.

  • Patent number: 9530334
    Abstract: A physically-discrete sign component comprises an internally-electrically-illuminated alphabetic character having a front-facing profile and at least one connecting bar disposed at least substantially horizontally with respect to the front-facing profile of the alphabetic character and at least partially within the front-facing profile of that alphabetic character. By one approach the physically-discrete sign component includes two of the connecting bars. If desired, these two connecting bars are disposed at least substantially parallel to one another. By one approach, a first one of the connecting bars extends partially, but not wholly, above an upper periphery of the aforementioned front-facing profile while the second connecting bar extends partially, but not wholly, below a lower periphery of the front-facing profile. The connecting bars can include a connecting-bar interface configured to physically and electrically interconnect to an adjacent sign component.
