  • Patent number: 9630856
    Abstract: A water treatment assembly generally in the form of a filter faucet generally of the type mounted on a sink or similar countertop surface. The water treatment assembly generally comprises a mounted valve assembly, an inline water filter, and a water spout. The inline water filter is configured intermediate the mounted valve assembly and the spout. The inline water filter has a watertight shell comprising a water inflow port and a water outflow port that allow the filter to be used as a readily replaceable and disposable modular filter cartridge. The filter inflow port allows for releasable fluid engagement with the valve assembly. The filter outflow port comprises a fitting for receiving the spout. Water flow through the filter and spout is controlled by the valve assembly. The combined assembly permits the new use of standard components improved in a cost effective manner to form a reliable filter faucet.

  • Patent number: 8997789
    Abstract: An apparatus for preventing backflow and contamination, and detecting by-pass leaks in a flow control arrangement is disclosed. The apparatus includes a vent line connecting a sweep gas source and a vent. Constant process-inert gas flows from the source through the vent line into the vent. The vent line is connected with the flow control arrangement. Any leakage in the flow control arrangement is channeled to the vent line and swept into the vent along with the sweep gas. As a result, pressure in the flow control arrangement cannot build up and leakage backflow is prevented. A flow switch may be disposed on the vent line for detecting leakage. The sweep gas flow rate is controlled at a constant level that is inadequate to actuate the flow switch and keeps the flow switch ready to actuate by any superimposed leakage. The flow switch detects a leakage when it actuates.

  • Patent number: 7017600
    Abstract: A faucet includes a base and a body. The body may be coupled and decoupled to the base with a bayonet fitting which is configured to prevent a forward rotation of the base relative to the body and to permit backward rotation and disconnection of the body from the base without the use of any tools. The faucet may have an internal chamber that houses a water sensitive device such as an electronics package and that is sealed from within and without by a system of seals located between the body and the base, between the base and a support surface, such as a countertop or a sink, and between individual components of the faucet.

  • Patent number: 7011106
    Abstract: A modular air gap device adapted for selective insertion into an associated faucet body and comprises a base, an inlet nipple defining an inlet passage and an outlet nipple defining an outlet passage. The inlet and outlet nipples project outwardly from the base in a first direction. An gap structure is connected to the base and projects outwardly therefrom in a second direction opposite the inlet and outlet nipples. The base and air gap structure are adapted for receipt within an air gap chamber of a faucet body. The air gap structure defines a flow path having a first end in direct fluid communication with the inlet passage of the inlet nipple and a second end spaced from the outlet passage of the outlet nipple so that an air gap is defined between the second end of the flow path and the outlet passage. A faucet including the air gap device defines a vent for venting the air gap chamber.

  • Patent number: 6971400
    Abstract: A dual inlet air gap fixture having an air gap body with first and second interior inlet conduits for receiving wastewater flow respectively from first and second identical or diverse sources of wastewater. The body has an interior outlet conduit opposite the inlet conduits for discharging wastewater emptying from either or both of the inlet conduits. A removable water reversal cap and partition module is received within the upper portion of the air gap body and provides venting communication between atmosphere and the outlet conduit, and redirects the wastewater from the inlet conduits into the outlet conduit. The inlet conduits are arrayed side-by-side on one side of the body interior space and the outlet conduit occupies the remaining interior space on the other side of space opposite from the two inlet conduits.

  • Patent number: 6776183
    Abstract: An aircraft drain device (14) for interposition between a potable water line (e.g., the drain line from an ice drawer) and a gray water line leading to a drainmast or other external drain. The drain device (14) includes a housing (30), an inlet (36) adapted for connection to the potable water line, an outlet (38) adapted for connection to the gray water line, and a piston (40). The preferably floatable piston (40) is movable between a normal operation position, whereat potable water can flow to the drainmast, and a back-up operation position, whereat the potable water is protected from contact with the gray water. The drain device (14) can be constructed to prevent spillage (or leakage) during back-up operation.

  • Patent number: 6435203
    Abstract: Disclosed is an apparatus and method for regenerating an etchant solution comprising metal compounds. When a sample of the etchant solution is determined to be of lower etching ability than a predetermined criteria as a result of the monitoring and analyzing three colors(red, green, and blue) of the etchant with color sensors in association with a microprocessor, the etchant solution is reoxidized by the addition of a suitable additive solution. The apparatus and method can regenerate spent etchant solutions containing heavy metals in a semi-permanent manner within the module device without wasting a portion of them, so that, in addition to producing no pollution of the environment, it is economically very favorable with an increase in overall etching efficiency.

  • Patent number: 6279598
    Abstract: Disclosed is an improved mixing eductor (10) of the type wherein the primary liquid (17), e.g., water, is in a main stream (201) flowing in a downstream direction. A venturi tube (51) is in the eductor (10) and has an annular sharp edge (131) in the main stream (201), thereby dividing such stream (201) into a primary stream (179) and a secondary stream (181) around the primary stream (179). The eductor (10) has an air gap (103) and a flow guide (47) downstream thereof. In a specific embodiment, the flow guide (47) is annular around the venturi tube (51) and the tube (51) and the guide (47) are in spaced telescoped relationship. Several embodiments of the eductor (10) and a new method for mixing liquids are disclosed.

  • Patent number: 6269833
    Abstract: A transfer system for transferring liquid from a liquid source to a reservoir which includes a fluid conduit having a coupling attached to an inlet end and an anti-siphon apparatus, having an upper and lower end, attached to an outlet end. The coupling may be a quick-connect coupling. The anti-siphon apparatus is mounted on the inlet end of the fluid conduit such that the lower end is located below the minimum water level of the reservoir and the upper end is located above the maximum water level of the reservoir. In addition, the upper end of the anti-siphon apparatus is located above the liquid outlet of the fluid conduit. The anti-siphon apparatus includes a baffle suitable for maintaining an air gap between water in the reservoir and the liquid outlet. Optionally, the transfer system may have an apparatus for removably mounting the system to an object such as a seal gate.
