Abstract: An automated low pressure fluid recovery system is disclosed. An eductor receives low pressure fluid from a source, for example vapors from a hydrocarbon tank. The eductor also receives high pressure fluid from another source, for example the output of a compressor or a well. By venturi principles the two fluid streams are mixed and a third intermediate fluid stream is formed, which is routed to a desired location. The low pressure fluids are thereby beneficially captured and sold or otherwise used. Various sensing devices, such as pressure and temperature sensors, emit signals to a programmable logic controller, which in turn automatically manipulates various control mechanisms to efficiently and safely control fluid flow through the system.

Abstract: The present invention concerns a system for converting printed receipts (PTR) into data files comprising an optical reader for acquiring a digital image of a printed receipt in the form of a printed list containing at least object identifiers having a predetermined format, an optical character recognition means for extracting from the digital image at least the object identifiers, a search means for collecting information about the objects in a database on the basis of said object identifiers, a generating means for generating a data file comprising at least said information collected in the database, and a supply means for supplying said data file.
