Abstract: A faucet spray head includes a diverter valve that has a diverter stem constructed and arranged to control water flow patterns. The stem includes a neck and a head that is larger than the neck. A shell encloses the diverter valve, and the shell has an opening through which the stem extends. A pivot member is coupled to the shell, and a rocker arm is pivotally coupled to the pivot member. The rocker arm has a retention opening, and the retention opening is adapted to slidably receive and retain the head of the stem during assembly of the rocker arm to the pivot member. The rocker arm is attached to the diverter valve in order to actuate the valve. The spray head includes lock pins that are configured to engage a lock insert that is secured to a spout.

Abstract: A faucet assembly includes a faucet hub, a hose, a hose retraction mechanism and a storage bag for storing any slack in the hose. The faucet hub includes at least one hose guide that is used to reduce the amount of wear on the hose. The retraction mechanism allows the hose to extend from the faucet hub. Once in the extended position, the retraction mechanism is configured to lock the hose in the extended position. Upon actuation by the user, the retraction mechanism can retract the hose back inside the faucet hub.

Abstract: The invention relates to a method for detecting an acid or base in an environment, measuring the concentration of an acid or base in an environment, or measuring the pH of an environment, by contacting the environment containing the acid or the base with a sensor, wherein the sensor is composed of an index of refraction transducer having an outer surface; at least one compound having at least one functional group of a Lewis acid, a Lewis base, a Bronsted acid, a Bronsted base, or a combination thereof, wherein the compound is on or near the outer surface of the transducer, wherein the functional group can interact with the acid or base in the environment to induce a change in index of refraction on or near the outer surface of the transducer, with the provisos that (i) the compound does not undergo a color change when contacted with the acid or base, and (ii) when there are naturally occurring functional groups, no transducer attached compounds, and exactly one overlayer, then the overlayer is not poly(vinyl
