  • Patent number: 10537094
    Abstract: Provided is a multi-tube nozzle for use in eradicating harmful aquatic organisms, which physically kills harmful aquatic organisms while feeding water and thus allows intake water to be fed directly into a culture tank or a ballast tank without the need for a pretreatment tank, chemicals, neutralizers, etc. A multi-tube nozzle (A) for use in eradicating harmful aquatic organisms includes at least three nozzle tubes (1) that are provided adjacent to each other. The nozzle tubes (1) each includes: an inlet-side opening section (2) having an inner diameter that decreases from an inlet opening toward a throat section (3) located in the middle of the tube; an outlet-side opening section (4) having an inner diameter that increases from the throat section (3) toward an outlet opening; and the throat section (3) having a smallest inner diameter. The adjacent nozzle tubes (1) are spaced apart by a distance such that the adjacent inlet-side opening sections (2) overlap each other.

  • Patent number: 10526808
    Abstract: The present invention relates to apparatuses for improving pool skimmers. In some embodiments, the apparatus is a pool skimmer basket system that includes a skimmer basket, a first tube that is attached to the skimmer basket, and a second tube that is adjacent to and rotatable relative to the first tube. The first tube includes a longitudinal slot that feeds water into the skimmer basket. Without being bound by any particular theory, it is believed that the slot increases the velocity of water flowing into the basket and that the system increases the debris-holding capacity and allows one to avoid having to reach through dirty water to remove the skimmer basket.
