Abstract: Interaction with various travel content sources is supported using any one of various known GDS cryptic code formats. Travel booking requests made in a selected GDS cryptic format are converted for communication with, e.g., a GDS content source, a direct connect content source, and/or a web-based content source and travel booking responses from such travel content sources is converted into a display format of the selected GDS. In this way, users familiar with one GDS cryptic format can continue to use that GDS cryptic format for interaction with GDS content sources of the same or different format, with direct connect content sources in their expected format, and with web-based content sources in their expected format.

Abstract: A method is disclosed for recycling industrial air. Air contaminated by particulates is removed from the area of machinery, transported to dust collectors, and filtered. A small portion of the filtered air is discharged to the outside atmosphere while a substantial portion is recycled to the area of the machinery. Significant savings of energy are realized while less particulates are exhausted with the air into the atmosphere as contaminants.
