Abstract:

A liquid dispensing system is provided for automated dispensing of a plurality of liquid reagents into a recreational body of water. The liquid dispensing system includes a cartridge apparatus housing a plurality of liquid reagent containers, each containing a respective liquid reagent. A docking assembly is provided having a dock manifold device, and is releasably coupled to the cartridge apparatus between a first condition and a second condition. In a first condition, the cartridge apparatus can be removably coupled to the docking assembly, while in the second condition, the cartridge apparatus is lockably mounted to the docking assembly in a manner permitting fluid communication from the respective reagent container to respective fluid passages of the manifold device. The dispensing system further includes a dosing engine having a valve manifold device to selectively dispense the liquid reagents into the recreational body of water through a dispensing port.

Assignee:

Idex Health & Science LLC - Northbrook IL

International Classification:

F16K 11/06

US Classification:

13762546, 251367

Abstract:

A micro-fluidic valve system is provided which includes a micro-fluidic valve actuator apparatus, a fluid distribution manifold and a micro-fluidic POD apparatus. The POD apparatus includes a POD housing that defines an interior central passage extending from a distal mounting end of the housing to a proximal portion thereof. The POD apparatus further includes a stator device disposed in the interior central passage, and includes a distal stator face that cooperates with an opening in the distal mounting end to define a gasket receptacle. A relatively thin, elastomeric gasket member is disposed in the gasket receptacle of the housing in abutting contact between the stator and a communication face of the manifold. A fluid-tight seal is then formed between each respective stator communication port of the stator device and a corresponding manifold communication port of the manifold.

US Classification:

137870000

Abstract:

A multi-position micro-fluidic valve system that includes an actuator assembly with a housing and a drive shaft rotatably disposed in the housing for rotational displacement about a drive axis thereof. One end of the drive shaft is configured to couple to a drive motor for selective rotation of the drive shaft about the drive axis. One of at least two different multi-position fluid valve devices can be removably mated to the actuator assembly. Each valve device is configured for rotational movement of a corresponding valve shaft about a valve rotational axis thereof between a plurality of discrete fluid distribution positions. A coupling device selectively and removably mounts the valve shaft of the respective valve device to the drive shaft of the actuator assembly. This enables selective positioning of the multi-position fluid valve device at a discrete one of the plurality for discrete distribution positions.

International Classification:

US Classification:

417321, 417521

Abstract:

A dual piston-pump apparatus is provided having a pump chassis that includes a pair of spaced-apart, elongated piston bores, and a lead screw shaft. This shaft includes a motor driven end, and another portion thereof rotatably mounted to the chassis for rotation about a screw rotational axis. A piston drive member threadably cooperates with the lead screw shaft for selective reciprocating movement longitudinally along the screw rotational axis thereof between a first position and a second position. The drive member includes a pair of spaced-apart piston shafts, each piston shaft of which includes a respective piston head slideably received in a respective piston bore of the chassis. As the drive member is driven along the screw shaft between the first position and the second position, each piston head is simultaneously reciprocated between a dispensing condition and an aspiration condition. An anti-rotation device cooperates between the pump chassis and the drive member to substantially prevent rotational displacement of the drive member relative to the pump chassis and about the screw rotational axis during rotational motion of the screw shaft.

International Classification:

B01L 3/00
F16K 99/00

Abstract:

A springless rotary shear that produces compression forces by utilizing the stiffness properties of polymer seals. The valve is designed to produce an effective spring load, with inherent sealing force, by deflecting polymer elements whose response depends on stiffness that is governed by each component's elastic modulus and geometry. A stator seal protrudes thousandths of an inch beyond a stator seal housing. When a stator is fastened down to the stator seal housing the clamping forces are transmitted to the stator seal, rotor seal, shaft adapter, bearings and housings, and the assembly is deflected to a flush position, resulting in a sealing force between the rotor and stator seal. The transmitted sealing force is as a function of the stiffness of each component and the protrusion distance of the stator seal above the mating surface prior to fastening the stator.

Abstract:

A liquid sampling system includes a liquid sampling valve for transferring a liquid sample from a primary stream to a secondary stream. The liquid sampling valve includes a rotor having a movable shuttle that is in selective fluid communication with the primary stream or the secondary stream. The rotor shuttle passes through a discharge station prior to completion of the valve cycle to discharge contaminants prior to re-exposure to the primary stream.
