Abstract: Tankless evaporators, refrigeration circuits, and water coolers use a drum as a thermal mass without using one or more tanks for storing water. Water coolers can include a tankless evaporator. Also described are refrigeration circuits suitable for a water cooler and which include a tankless evaporator. An evaporator for use in a fluid chiller includes a drum of heat conductive material defining a thermal mass, a water coil disposed adjacent around the drum, an evaporator coil configured around the drum and adjacent to the water coil, in which the evaporator coil is operative to cool the water coil.

Abstract: A wall mounting system is described having a wall mounting bracket to be rigidly secured to a wall, a pair of water bottle filling station-mounted brackets to be rigidly secured to a water bottle filling station, and a pair of bracket adaptors, each configured to be secured to a respective one of the water bottle filling station-mounted brackets and to the wall mounting bracket. The system can include one or more springs. The system allows an operator to properly install a water bottle filling station on uneven walls or damaged or improperly installed wall mounting brackets.

Abstract: The shower head nozzle as disclosed herein includes a quick-connect coupling for selectively attaching the nozzle to a downwardly extending conduit or tube for directing tested water through a test unit and into a bucket or drain, wherein the test unit may include a flow meter for measuring real-time water flow rate and a temperature sensor for measuring real-time water temperature dispensed from the shower head, thereby reducing the testing time, more accurately determining flow-rate and water temperature, and decreasing the amount of waste water.

Abstract: The emergency shower includes a discharge outlet pivotable between a first non-use position and a second deployed position about a rotary union, for dispensing water therefrom. A ball valve is positionable between a first flow restricting position and a second flow permitting position, when the discharge outlet pivots between the first non-use and second deployed positions. A linkage system actuates ball valve movement when the discharge outlet pivots, by way of a first link pivotally coupled relative to the discharge outlet and movable therewith and a second link pivotally coupled with the ball valve and responsive to movement of the first link, the second link positions the ball valve in the first flow restricting position when the discharge outlet is in the first non-use position and commensurately moves the ball valve to the second flow permitting position when the discharge outlet pivots to the second deployed position.

Abstract: Embodiments provide a stand-alone or self-contained gravity-fed emergency shower including a shower head. A water-tight reservoir is provided, the reservoir including an outlet in fluid communication with a shower head, and an air inlet pipe. The air inlet pipe includes an interior end and an exterior end, the interior end extending into the reservoir to a point below the fill level and above the outlet. The air inlet pipe allows air to enter the reservoir as water drains through the outlet, maintaining a substantially constant head pressure at the outlet, thereby resulting in a substantially constant flow rate of water to the shower head.

Abstract: The reversible drain basin disclosed herein includes a longitudinally extending base having an inlet generally formed from one side of the base and an outlet generally formed from another side of the base and in fluid communication with the inlet via a passageway therebetween. An attachment mechanism associated with the base is configured to selectively reciprocally attach the reversible drain basin to a liquid supply system in a first forward position extending the outlet over a collection basin and a second rearward position extending the outlet a distance sufficient for engagement with a wall-hidden drain pipe without reorientation of the liquid supply system.

Abstract: An automated traffic control process and system providing automatic remote monitoring the locations of one or more remote vehicles, determining which vehicles fall within one or more preference categories, and if a vehicle in a particular preference category is detected as approaching a remote intersection, issuing a preemption instruction to a traffic signal controller for the remote intersection.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
