Abstract: A method and system for conducting electronic auctions is described. A mic lot closing extension feature avoids collisions in closing times of multiple lots by dynamically extending the closing time of a subsequent lot if a preceding lot's closing time is extended to be too close to the subsequent lot's then-currently can be extended with a flexible overtime feature, in which the properties of the event triggering the extension and the of the overtime period(s) can be tailored to a particular auction, particular lots of products within an auction, and to the particular time within an auction process. t can be set to a “pending” status after the nominal closing time for submission of bids to allow bidders to alert the auction coordinator of technical problems in submission of bids. This allows the possibility for a lot to be return to bidding by all bidders.

Abstract: A method and system for conducting electronic auctions is described. A dynamic lot closing extension feature avoids collisions in closing times of multiple lots by dynamically extending the closing time of a subsequent lot if a preceding lot's closing time is extended to be too close to the subsequent lot's then-currently scheduled closing time. Scheduled closing times can be extended with a flexible overtime feature, in which the properties of the event triggering the extension and the duration of the overtime period(s) can be tailored to a particular auction, particular lots of products within an auction, and to the particular time within an auction process. The bidding status of a lot can be set to a “pending” status after the nominal closing time for submission of bids to allow bidders to alert the auction coordinator of technical problems in submission of bids. This allows the possibility for a lot to be return to open status for further bidding by all bidders.

Abstract: There is disclosed an apparatus and process for detecting changes in the density of a gas wherein the gas to be measured is introduced into a closed casing at the rotary axis of a hollow disc wheel rotating within the casing. The disc wheel is provided with a plurality of radial vanes and the gas is centrifuged by the rotating disc. A Pitot tube positioned at the periphery of the disc measures the force exerted by the centrifuged gas to ascertain its mass which is then compared with a reference pressure.
