Abstract: Candles are provided with a band on a wall of their outer housing for sealing an air treatment chemical placed adjacent the housing. The candle includes a housing containing a combustible fuel. An air treatment chemical is mounted on a radially outward portion of the housing in a position where it can be heated through a side wall of the housing by the fuel when it is combusted. A seal is positioned over the air treatment chemical to inhibit dispensing of the air treatment chemical prior to combustion of the fuel, and is removable to permit the air treatment chemical to be dispensed when the fuel is combusted.

Abstract: A faucet has a body with a hollow inner cavity and a spout which opens into the inner cavity. A valve assembly is located within the inner cavity to control the flow of water from a source into the spout. The valve assembly comprises a housing with an inlet chamber which opens into a ring-shaped channel, an outlet chamber having an opening centrally located with respect to the ring of the channel, and a diaphragm to selectively close the communication of the inlet and outlet chambers. A solenoid includes a plunger that is biased by a spring against the diaphragm and an electromagnetic coil to pull the plunger away from the diaphragm. A proximity sensor is included to detect the presence of an object adjacent the faucet and energize the coil. A safeguard alarm mechanism is provided to deenergize the coil after a given interval if the object continues to be detected and thereafter periodically briefly energize the solenoid until the object is removed.
