| 20110139900 | DISPENSING SYSTEM AND METHOD FOR SHOWER ARM - Dispensing systems for dispensing one or more materials into a fluid flow conduit, during the conveyance of fluid through the conduit are configured to connect to a fluid conduit, such as a standard pipe of a shower arm and dispense a material into the water flow in the shower arm. The system includes a first tube member having a restrictor flow passage to provide a pressure differential, as fluid flows through the tube member. The pressure differential created within the restrictor passage by the fluid flow is communicated to a flask, to provide a pressure differential between the interior and the exterior of a flexible container within the flask. The pressure differential causes material within the flexible container to be drawn out and conveyed to the fluid flowing through the tube member. The flask may be connected to the first tube member, through an extension portion that is rotatable around the first tube member for convenient positioning. A quick-release connection structure may allow the flask to be connected and selectively releasable from the system. | 06-16-2011 |

| 20140183280 | Flow Device - A flow device automatically impels a fluid to disperse from a container without requiring significant physical exertion, such as a repetitive pumping motion, to propel the fluid through. The flow device automatically causes an intake fluid to flow from an intake end of a container, and pass through an interior channel of the container. The intake fluid helps force a dispersion fluid inside the container to disperse through an opposite, dispersion end without requiring a manual motion, such as a pumping action with a finger. The flow device includes a switch that actuates a pressure differentiation portion, such as a fan, vacuum, pump, or compressor, to create a vacuum or redirection of intake fluid within the container sufficient to create the flow for the intake fluid to pass through the container. The automatic switch negates the need to flex and stress joints in a hand. | 07-03-2014 |
| 20140231548 | Chemical Application Apparatus for Sprinkler Systems - A liquid chemical dispenser for an irrigation system comprises a removable supply container for the chemical which, in a first embodiment, comprises a valve for preventing spillage of the chemical during attachment of the container to the dispenser.
