Abstract: An apparatus and method for tracking use of an electrical device, such as a tattoo machine, by an operator in the tattoo industry. A power switch is coupled to a power source and a computer system. The computer system executes software which in response to user input activates the power switch, enabling current to flow from the power source to the electrical device coupled to the power switch. The software tracks a time elapsed during which the power switch is activated. The software can generate billing and audit information based on the time during which the power switch is activated.

Abstract: A stable, pourable clear or translucent fabric conditioning composition comprising one or more cationic fabric softening materials having an iodine value of from 5 to 140, one or more oils and/or low molecular weight solvents, and one or more hydrophobic fluorescers.

Abstract: Data processing systems and methods for managing transactions in auction-based trading of specialized items such as fixed income instruments are presented. The data processing system provides a highly structured trading protocol implemented through a sequence of trading paradigms. The system employs a distributed computer processing network linking together a plurality of commonly configured program-controlled workstations. The protocol and its program-controlling logic improves trading efficiency, rewards market Makers, and fairly distributes market opportunity to system users.

Abstract: The present invention is systems and methods for trading. In accordance with these systems and methods, a plurality of trader work stations that are connected to a central server may be provided. Through the work stations and central server, the systems and methods may perform participant qualification, instrument creation, bid/offer entry and response, when hit and take, workup, price retention, price improvement, request for market, bid/off restoration, price generation, position conversion, marking to market, and delivery functions.

Abstract: The efficiency of mixing vapor in a countercurrent column (1) is improved by use of one or more vapor risers (6) each incorporating a mixing device (7). The method is suitable for use in countercurrent columns operating at high pressures or under vacuum. For high pressure operation a single riser is preferred positioned in the center of the distributor tray (5).
