摘要： A method can be performed by adjusting a temperature of a gas sensor to a first temperature value for a first period of time and a second temperature value for a second period of time. The gas sensor signal may be measured during the first period of time to determine a first signal value and during the second period of time to determine a second value. Then, concentration information for at least one gas is calculated according to the first signal value and the second signal value. While the gas sensor signal may include information about a presence of a first gas and a second gas, the concentration information for the at least one gas may not substantially include concentration information for the second gas.

摘要： The open ended wrench includes a manually graspable handle and a nut-seizing jaw formation connected to the handle. The jaw formation has a nut-receiving opening therein defined between an upper jaw member, a lower jaw member spaced a fixed distance from the upper jaw member and a jaw back portion extending between the upper and lower jaw members. A slot communicates with the opening and extends through the jaw back portion. A plurality of substantially equal length shims are longitudinally slidable through the slot from a location outside of the opening to a location inside of the opening to provide a variable dimension for the nut-receiving opening. Each of the shims has an interlock formation for preventing any shim from being located inside of the opening unless there is supportive contact with the jaw. In one embodiment, each shim has one end thereof formed with an offset end portion including an inclined section extending angularly from the plane of the shim and an end section extending from the inclined section. The offset end portion defines the interlock formation. In another embodiment, some of the shims are from a first group of shims which are rolled from stock having a first thickness dimension and some of the shims are from a second group of shims having a second thickness dimension slightly larger than the first thickness dimension. Each group of shims has essentially the same tolerance range, whereby nesting and stacking of said two groups of shims having different basic thickness dimensions is facilitated. Also, the wrench includes a manually manipulatable releasable locking assembly for releasably locking the shims in a desired position against the upper jaw member.

摘要： Apparatus for the detection of a vapor of a selected chemical substance includes a sensor whose impedance changes upon exposure to such a vapor. The sensor comprises a polymer whose physical structure is altered by the vapor, e.g., through expansion or disintegration, and electrically conductive elements that are interspersed with or separated by the polymer. The interspersed elements may consist of a fine powder of carbon or of a metal in a matrix of silicone or other vapor-sensitive polymer. The electrical contacts between the powder particles are weakened when the polymer swells or disintegrates, which results in increased resistance. Alternatively, the capacitance between two conductive layers separated by a polymer layer decreases, and hence the impedance increases, when the polymer swells upon exposure to the vapor. In yet another embodiment, the polymer exerts a stress on a piezoresistive element and the stress is increased when the polymer swells, which causes a further increase in resistance. The changes are measured by an impedance-measuring circuit, such as a Wheatstone bridge.

摘要： An optical waveguide sensor for the detection of acid vapors comprises a chemically sensitive reagent coating of bromothymol blue or thymol blue indicator suspended in a Nafion polymer film. The sensor uses a 562-nm light-emitting diode source and a phototransistor detector. The response to HCl and H.sub.2 S vapors is both rapid and reversible, with an estimated detection limit for H.sub.2 S of less than 15 ppmv (parts per million by volume). The sensor exhibits generalized response to protonic acid vapors, but does not produce an indicator response to CO.sub.2, even at large concentrations (60 volume-%) in the presence of water vapor. The sensor exhibits a systematic interference from water vapor which may be corrected by a differential approach, either using a reference sensor (Nafion without an indicator) or by monitoring the sensor responses at two wavelengths.
