摘要： A modular deck drain system comprising a bottom channel and an upper cover. The bottom channel has a pair of opposed side walls and a bottom surface coupled to the side walls. The bottom channel also has a plurality of stabilizing members coupled to and extending from an external surface of the bottom channel, and at least one modular junction node. The upper cover is configured to couple to the bottom channel. The upper cover has two upper walls, each wall having a top end and a bottom end, and the top end of each wall is coupled to an upper lip. A narrow top opening is formed by the upper lips. The upper cover has at least one cutline.

摘要： A pipeline filter assembly comprising a base assembly, an outer wall, and a lid assembly. The base assembly comprises a filter base, a base plate, and a support collar. The outer wall has a lower end portion and an upper end portion, wherein the lower end portion is coupled to the base assembly and the upper end portion comprises a lower collar. The lower collar comprising at least one lock notch spaced around an exterior surface thereof. The lid assembly comprises an upper collar and an upper cover. The upper collar comprises at least one housing that projects from the upper collar, at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch, and at least one biasing spring that biases its corresponding biasing clip to a locked position around a corresponding lock notch.

摘要： An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing and configured to generate ozone, an ozone inlet fitting removably coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a spring-loaded clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.
