    Abstract: A battery charger 10 includes a capacitor 20 which establishes a level of current sufficient to fast charge in one-hour a battery 18 having from one to twenty cells. An SCR 16 is controlled by a timer 42 to initially delay the supply of current while determining whether the battery 18 is hot or cool. If battery 18 is cool, charger 10 proceeds to fast charge the battery. After battery 18 is fully charged, the battery heats to a temperature where a NTC thermistor 58 responds to trigger a second timer 52 which controls SCR 16 to stop the fast charging operation. Charger 10 is then controlled to prevent the charger from thereafter re-entering a fast charge mode.If battery 18 is initially hot, charger 10 is controlled to further delay the initiation of a fast charge operation until the battery cools to or below the charge-start temperature.A second NTC thermistor 90 is provided to compensate for the potential effect on the operation of thermistor 58 in response to temperature levels emanating from any environment other than from battery 18.

    Abstract: Ion-selective compositions which comprise an ion carrier, a compound capable of solvating the ion carrier, and a supporting matrix are disclosed. The ion carrier according to the invention is a lipophilic hemispherand compound. These compositions are particularly useful in ion-selective electrodes. Such an electrode is capable of selectively transporting a first ion in preference to a second ion. Particularly useful hemispherands have a .DELTA.G of complexation with the first ion which is at least 0.3 Kcal/mole greater than the .DELTA.G of complexation with the second ion. Dry-operative electrodes using these ion-selective compositions as membranes are also disclosed.

    Abstract: A particular class of triarylmethane leuco dyes are useful in analytical compositions, elements and methods. These leuco dyes are triarylmethane compounds having an aromatic heterocyclic moiety attached to the central methane carbon and which, upon interaction with hydrogen peroxide, provide dyes having a maximum absorption at a wavelength equal to or greater than about 600 nm. Particularly useful leuco dyes have the structure: ##STR1## wherein R is a 5- to 15-membered aromatic heterocyclic moiety; and R' and R" are independently open chain or cyclic amines. These compounds are useful for providing detectable dyes in compositions and elements useful for detection of hydrogen peroxide or other analytes which react to produce hydrogen peroxide in aqueous liquids, e.g. biological fluids.
