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: 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 panel assembly which comprises panels having astragals adapted to be attached to the segments of a segmented column and adapted to be rotated about the axis of the column to a position in which one panel forms an angle with another. One or more additional panels may be added to the column. The panels have load supporting means and the column does not.
