Abstract: The invention comprises an apparatus and method for the hands-free controlling of the on and off operation and temperature of the water flow from the spout (100) through the use of proximity sensors (10) that detect the proximity of a person's hand (H) relative to the spout. The spout (100) therefore functions as a transmitter antenna (170) to emit a time varying electrostatic (primary) field (Fp). When a portion of a person's body such as a hand (H) or finger enters the field, the primary field (Fp) is coupled to the person's body. The person's body then radiates a secondary field (Fs) in syncopation with the primary field (Fp). An antenna receiver (140) is located behind the front panel of the vanity of the sink (100) to receive the secondary field (Fs). Electronic circuitry (200) including a microprocessor with software then processes the received signal to perform the desired functions.

Abstract: A hot and cold water faucet having a concave base and hot and cold water outlets in the base which, following the concave curvature, are positioned forwardly of a rearwardly located inlet into the faucet, and thus the water connections from opposite directions to the faucet inlet converge at an angle rather than head-to-head and this contributes to better mixing into a luke warm temperature of the water flowing into the faucet.

The ledge 116 is formed with a pair of spaced tabs 118 and 120 extending from one side of the ledge and an elongated hole 122 formed in the ledge between the tabs. A pair of bosses 124 and 126 with holes 128 are formed in spaced portions of the body 106. The tabs 118 and 120 of the throat plate 104 are located in the channels 80 of the putty plate 54 and the latch bar 78 is located in the hole 122 to retain the throat plate with the putty plate as an assembly.

Abstract: A combined safety shower and eyewash station utilizes steam to heat water in a heat exchanger. Cool water is combined with heated water from the water outlet of the heat exchanger by a temperature-regulated mixing valve. If the water at the water outlet of the heat exchanger becomes too hot, some of the water is fed to the steam inlet of the heat exchanger. This makes it easy for the mixing valve to regulate water temperature even though the shower uses water at a much higher rate than does the eyewash station. Steam is fed to the heat exchanger through a steam valve which is opened automatically when a demand for warm water is sensed by a pressure-drop flow sensor. An overtemperature responsive actuator overrides the demand sensor to shut off the steam. A steam trap at the inlet of the steam valve eliminates cold condensate so that the apparatus is able to deliver warm water substantially immediately upon demand.
