Abstract: Methods and compositions for detecting free radicals, the compositions being spin trapping compounds comprising a nitrone having a detecting moiety and optionally having a targeting moiety for targeting the nitrone to an organ, a cell, an organelle or a molecule of interest for directly detecting free radicals, especially free radicals in biological samples.

Abstract: A gaming machine (10) is provided having a plurality of modules. The gaming machine (10) may be used to provide a flexible architecture gaming machine. The plurality of modules include a play module (12) containing a display device (14) and a computational device (100) for controlling the operation of the gaming machine (10), and a base module (24) shaped and dimensioned to either directly or indirectly support the play module (12). The play module (12) includes a communication interface device (104) operable to communicate with a transaction handler that may be a transaction handling module (16). Also described and claimed is a method of supplying and a method of manufacturing a flexible architecture gaming machine.

Abstract: An air separation apparatus and method for producing a gaseous oxygen product at a delivery pressure. A, filtered, compressed and purified air stream is formed and preferably divided into first and second air streams. The air contained within the first air stream is separated by a low temperature rectification process operating in accordance with a Claude cycle to produce liquid oxygen in a lower pressure column with a double column air separation unit. A Claude expander expands at least a major portion of the air contained within the first air stream into the high pressure column. The second air stream is compressed and partially cooled and is then expanded with the performance of work which is in turn applied to the work of compression of the second air stream. Liquid oxygen is pumped from the lower pressure column to substantially the delivery pressure and is vaporized within a mixing column against the second air stream which is also introduced into the mixing column.

Abstract: An air separation apparatus and method in which a high pressure gaseous product is produced as a liquid, pumped to a delivery pressure and then vaporized prior to its discharge as product. In order to accomplish the requisite vaporization, a subsidiary stream of incoming air is compressed by a booster compressor and then passed into indirect heat exchange with the pumped liquid in a falling film evaporator. The falling film evaporator maintains an essentially constant temperature difference between the air and falling film, formed of the pumped liquid. As a result, a very small temperature differences can be maintained as compared with the conventional use of a thermosyphon reboiler. As a result, less booster compression is required for the subsidiary air stream over a prior art plant.
