Including Bypass Patents (Class 422/282)
  • Patent number: 10773979
    Abstract: A passive fluid treatment assembly is provided including a passive treatment body defining a primary flow path and a liquid treatment path. The liquid treatment path bypasses a portion of the primary flow path and enters a treatment enclosure through a high pressure port. The fluid entering the high pressure port is treated by a treatment media in the treatment enclosure and exits through a low pressure port into a mixing chamber where it is remixed with the fluid in the primary flow path. A one-way valve is operably coupled to an outlet of the high pressure port for preventing the flow of treated fluid from exiting the treatment enclosure through the high pressure port.

    Abstract: Treating, sensing, diverting, measuring, and collecting devices for fluid such as water are described. When designed for use as chlorinators, the devices may divert water flowing in conduits into the devices for treatment and subsequent return to the flow stream. A return tube of the device may be designed to create vortex action, using a pressure differential to evacuate treated water from the device back into the conduit. When designed for use as feeders for supplying acid or other material to flowing water, the devices may include one or more channels communicating between the material and the flowing water. When designed for use as flow sensors or otherwise, the devices may include objects acted upon by flowing water to indicate that water indeed is flowing. Yet other sensors may be utilized to determine characteristics of water passing through the conduits.

  • Patent number: 7690392
    Abstract: A mixing body for diverting a portion of a liquid, e.g., water flow, into a cartridge of fertilizers, fungicides, hormones, pesticides or the like to form effluent. The effluent is reintroduced to the water flow and goes to a downstream sprinkler or application system. The cartridge, which may contain liquid concentrate, is inserted into the mixing body, which has inlet and outlet one way valves that puncture a sealing layer of the cartridge. The diluted effluent exits through the outlet one way valve and is thus delivered to the irrigation system. The amount of effluent can be regulated by a needle valve that controls the amount of effluent exiting the manifold. The mixing body has a locking system to securely hold the cartridge in place. There is also a plate to protect a user from the sharp inlet and outlet valves when the cartridge is removed.

The chlorinator is submerged and the container has an opening to allow water from the pool to flow into the container and dissolve the tablets. A duct from the bottom of the container leads to the interior of the flow pipe. The duct extends into the flow pipe to constrict the flow through the pipe, so that this flow causes chlorinated solution to be aspirated from the container into the flow by means of the Venturi effect. The container is transparent so that the chlorine tablets are visible from outside the container. The container further has a removable lid for refilling the container. The container opening comprises a slotted hole in the lid, with a sliding plate that can be moved over this slot to vary the size of the opening and thereby regulate the flow through the container.

  • Patent number: 5730178
    Abstract: A device for introducing substances into water in bathing, showering and similar systems has a body, a water inlet passage, a water outlet passage, an element for connecting the body to a container which accommodates a substance to be introduced to water, an opening communicating the water inlet passage with an interior of the container so that water flows into the interior of the container from the water inlet passage to be enriched with a substance, an opening communicating the interior of the container with the water outlet passage so that the water enriched with the substance can flow from the interior of the container into the water outlet passage, and a resistance between the water inlet passage and the water outlet passage so that a pressure in the water outlet passage is lower than a pressure in the water inlet passage and therefore a suction is created in the water outlet passage so as to aspirate the water enriched with the substance from the interior of the container into the water outlet passage.

  • Patent number: 5607651
    Abstract: A multiple product dispensing system includes a plurality of use solution dispensers and a controller for selecting one of the dispensers according to a preset regimen, e.g., selecting different dispensers on different days of the week. Each dispenser dispenses a controlled concentration of use solution using a diluent delivery apparatus that delivers a diluent to form a liquid concentrate from a solid chemical composition, and to form make-up diluent for diluting the liquid concentrate and forming a use solution of controlled concentration. A foam reducer reduces the kinetic energy of the make-up diluent prior to mixing with the liquid concentrate to reduce foaming. An unskilled operator may operate the dispensing system to dispense a use solution of carefully controlled concentration, and the controller will automatically select the proper dispenser according to the preset regimen, without any additional input on the part of the operator.

  • Patent number: 5599509
    Abstract: In a metal catalyst converter configured of the metal catalyst carrier that holds the catalyst into the honeycomb body created by alternately winding flat sheet and corrugated sheet, a plurality of slit matrix that extend in the direction perpendicular to the exhaust gas direction were arranged on at least one part of the upstream side of the exhaust gas passage. By that a low heat capacity and high heat transfer area in regard to the downstream side of the exhaust gas passage was formed. The upstream portion of the metal catalyst converter on which slit matrix was formed was configured to be covered by outer casing having an air insulation layer.

  • Patent number: 5342587
    Abstract: A detergent dispenser that is utilized with solid cast detergent. A single valve is utilized to initiate a flow of a ready to use detergent solution that may be drawn off in container. The valve commences a flow of water that is split in a T-shaped fitting. An appropriate portion is routed to spray on the solid cast detergent and to dissolve the detergent into a concentrated solution. The concentrated solution flows into a conduit where it is mixed with the second portion of the water, diluting the solution to an appropriate concentration for use. A restricter located in the T-shaped fitting acts to split the flow of water appropriately to ensure that the discharge solution is in a ready to use concentration.

  • Patent number: 5262132
    Abstract: An apparatus for dispensing solid or semi-solid detergents includes a hollow elongated opening or chute and an arcuate plate that extends from the side wall of the apparatus to beneath the chute. This plate provides a planar support for a detergent bar placed within the chute. Water is sprayed down the arcuate plate and projects against the detergent supported on the planar support causing it to dissolve and flow down a drain. The chute has a unique geometric design which is suitable to receive only one uniquely shaped elongated detergent bar. In a kitchen having several detergent dispensers, each detergent dispenser will have a uniquely defined chute so that only the appropriate detergent can be used in the appropriate dispenser.

  • Patent number: 5178181
    Abstract: A fertilizer applicator is provided for use with a sprinkler line system. The applicator comprises a fertilizer container with integrally formed internal inlet and outlet tubes. Water is fed through an inlet-outlet tube into the bottom of the fertilizer container, where it dissolves or dilutes some of the solid or liquid fertilizer and forms a leached, concentrated solution. This concentrate continuously rises through the fertilizer and into the outlet tube where it drains downwardly. The concentrate is then diluted with water coming through the inlet-outlet tube including a venturi, the size of which controls the flow rate of the concentrate. The diluted concentrate is then passed into the sprinkler system for application to vegetation. The applicator has a single piece, simplified design, without moving parts, and does not leak fertilizer into the drain.
