20140047634 | Emergency Eyewash Unit - An emergency eyewash unit includes a pair of water discharge ports oriented to produce a pair of upwardly directed, diverging water streams for inside-out flush flow of contaminants from a person's eyes. These eyewash streams can be combined with a plurality of smaller upwardly directed facewash streams for flushing contaminants from a person's face. The eyewash and/or facewash streams are produced by an eyewash body adapted for rotatable mounting onto a water supply conduit, with a locking clip normally preventing undesired rotational disassembly. The eyewash body may be used in combination with an overhead emergency shower which, in one preferred form, includes a shower spray head carrying multiple flow control and flow shaper elements to produce a substantially uniformly dispersed shower spray pattern. | 02-20-2014 |

20120104107 | THERMOSTATIC MIXING VALVE UNIT - A thermostatic mixing valve unit in an emergency wash unit has an integrated housing with cold and hot water inlets each having an associated check valve, and a tempered water discharge having a thermostat for cold/hot water mixing to provide a predetermined tempered water discharge. A high temperature limit valve responds to the water discharge temperature to permit or prevent hot water inflow when the water discharge exceeds a preset temperature. A cold water bypass valve is coupled by a diverter valve to the lower of the cold and hot water supply pressures to maintain a substantial water discharge flow when the high temperature limit valve restricts hot water flow or when the hot water check valve is stuck closed, or upon failure of the cold water supply as by sticking of the cold water check valve in a closed position or by a clogged filter screen. | 05-03-2012 |
20120096639 | FAUCET MOUNTED EYEWASH UNIT - A faucet mounted eyewash unit for installation onto the discharge end of a standard faucet spout. The eyewash unit in a normal faucet mode position permits uninterrupted water flow through the faucet spout. In an eyewash mode, a portion of the eyewash unit is rotated quickly and easily to orient a pair of eyewash discharge ports in upwardly open positions, and to couple these eyewash discharge ports to the water flow for upward trajection of a pair of eyewash flushing streams. The eyewash unit further includes a thermostat for preventing hot water flow above a selected temperature level to the eyewash discharge ports. | 04-26-2012 |
20110316273 | DUAL SEAL TUBE FITTING - A dual seal tube fitting is provided for quick and easy, substantially leak-free coupling with plastic tubing or the like in a water supply application, such as in a drinking fountain or the like. A reinforcing metal sleeve is slidably received into the end of a length of tubing which is then slidably received into a central bore of a fitting body having a resilient seal ring seated therein for sealingly engaging an outer diameter surface of the tubing. A compression ring is slidably received onto the tubing in a position over a portion of the internal sleeve therein, and is compressibly retained between the tubing and a fitting body seal face by a compression nut threaded onto the fitting body. The resilient seal ring thus provides a primary seal preventing leakage between the tubing and fitting body, whereas the compression ring provides a secondary seal. | 12-29-2011 |
20090308494 | HYDRATION STATION - An improved hydration station comprises a wall mounted unit including a stationary lower body panel coupled to a drain, and a hinged upper body panel carrying a nozzle subassembly for dispensing water into a recess alcove defined cooperatively by the lower and upper body panels in response to user-insertion of a water-receiving receptacle into the alcove. The preferred wall unit includes a non-contact sensor for controlling water dispensing flow, and a preferred nozzle assembly includes at least one component having an antimicrobial additive. A preferred control timer automatically dispenses water in the event that the sensor does not detect a user-inserted receptable within a predetermined time interval, such as 24 hours. In addition, in a preferred form, lights on the unit are energized at one level during water dispensing, and at a second level when water is not being dispensed. | 12-17-2009 |
