A liquid laundry detergent dispenser for an automatic washing machine employs a reservoir that holds a quantity of the detergent sufficient for numerous wash cycles. An air/fluid chamber fills through a check valve from the base of the reservoir. To commence a dispense cycle, a timer circuit is actuated to run an air pump that supplies air under pressure through an air hose to the air/fluid chamber, and this displaces the detergent from the chamber and through a detergent dispense hose into the tub or drum of the washing machine. At the end of the dispense cycle, a bleed valve opens to relieve pressure on the air hose and the air/fluid chamber. The automatic detergent dispenser can be attached to existing washers or built in. A multiple arrangement can be used with a bank of washers at a commercial laundry.

An atmospheric valve is in fluid communication with the cylinder, and automatically opens to recharge the cylinder once the initial pressure charge has been delivered to the tire.

A continuous monitoring method and system wherein a porous substrate or film is used. The air from the environment is drawn through a region of the porous substrate by a simple air pump and the substances in the air are deposited or chemically adsorbed onto the surface of the substrate. The region of the substrate where the environmental air is drawn through is continuously monitored by an optical or spectrometric method. The substrate is in the form of a tape supplied by a feed reel in a reel-to-reel cartridge and taken up by a take-up reel as found in a film cartridge or a magnetic tape cartridge. The cartridge can be replaceable. A variety of materials may be employed as the substrate with an adequate surface area to effect accumulation of solid, liquid, aerosol, or gas phase compounds. An optical interrogation system is engineered such that the surface of the tape at the point where air from the environment is drawn through the substrate becomes the interaction region between the source output and the sample. As material from the environment accumulates in this region, the interaction of the source with the material is monitored by a suitable detector and supporting circuitry.
