An ion mobility spectrometer includes a housing with a flow channel, an air pump to force air through the flow channel, a heater at an inlet end of the flow channel, and an ionization source that ionizes the air after it is heated. The heated, ionized air passes through an electric field produced by a field source and a plurality of sensor elements located within in the wall of the flow channel in the measurement region of the electric field. The sensor elements include a plurality of sensor electrodes in one wall of the flow channel. Ion currents to the sensor electrodes are measured by an integrated high-sensitivity readout circuit array, permitting the sensor electrodes to be quite small. The sensor electrodes may be arranged in one-dimensional or two-dimensional arrays.

A cleaning system utilizing a pressurized dense-phase cleaning fluid includes a cleaning containment vessel having a containment-vessel interior, and a pressurization source in fluid communication with the containment-vessel interior to produce a cleaning pressure therein. There is at least one ultrasonic energy source directing ultrasonic energy into the containment-vessel interior. Where there are two ultrasonic energy sources, they desirably function at different frequencies. Each ultrasonic energy source includes a transducer housing having a transducer-housing interior, an ultrasonic transducer within the transducer-housing interior and directing a beam of ultrasonic energy through the transducer housing and into the containment-vessel interior, and a gas-pressure source in fluid communication with the transducer-housing interior. The gas-pressure source produces a pressure in the transducer-housing interior substantially equal to the cleaning pressure.

A thermal electrochemical system in which an electrical current is generated between a cathode immersed in a concentrated aqueous solution of phosphoric acid and an anode immersed in a molten salt solution of ammonium phosphate and monohydric ammonium phosphate. Reactants consumed at the electrodes during the electrochemical reaction are thermochemically regenerated and recycled to the electrodes to provide continuous operation of the system.

The composition of an electrically conductive mixture, such as a mixture of gasoline and alcohol, is measured using a single measurement cell having a first electrode and a second electrode with a measurement space therebetween for receiving a specimen of the mixture. With a specimen of the mixture in the measurement space, the first electrode is alternatively connected to a reference discharge voltage, preferably ground, and to an applied voltage through a resistor. A first operational state encompasses the period when the first electrode is connected to the reference discharge voltage and a second operational state encompasses the period when the first electrode is connected to the applied voltage through the resistor. A first operational state peak voltage is measured during the first operational state, and a second operational state peak voltage is measured during the second operational state. The first operational state peak voltage and a preselected constant proper fraction of the second operational state peak voltage are summed to obtain a summed voltage output, which may be correlated to the composition of the mixture.

An improved liquid carbon dioxide dry cleaning system containing an improved dry cleaning fluid. The dry cleaning fluid contains an antistatic agent for dissipating static charge on members or garments generated by friction during cleaning thereof. The concentration of the antistatic agent is typically less than 1 percent. Static charge present on the members or garments that are cleaned is transferred through the dry cleaning fluid to ground. This transfer of charge minimizes static charge buildup on the members or garments and suspended soil redeposition onto the members or garments. An odorizing agent or fragrance, and/or a deodorizing agent may be added to the cleaning fluid.

A thermoelectrochemical system in which a continuous electrical current is generated from a heat input below about 250. degree. C. A hydrogen ion reacting cathode is immersed in a chosen Bronsted acid and a hydrogen ion reacting anode is immersed in a chosen Bronsted base. Reactants consumed at the electrodes during the electrochemical reaction are directly regenerated thermally below about 250. degree. C. and recycled to the electrodes to provide continuous operation of the system.
