Abstract: A method receives an electronic image and uses the image as an input to a neural network. Based on a determination that the image represents a document, the method uses the image as an input to another neural network to identify a portion of the document containing an identifier. The method extracts the identifier by performing character recognition on the identified portion and determines whether the identifier is valid by using a validation API to determine whether the identifier is associated with a valid account at an institution. Based on a determination that the identifier is associated with a valid account, the method authorizes a transaction associated with the identifier. Based on a determination that the identifier is not associated with a valid account, the method denies the transaction. The first neural network classifies the electronic image into one of multiple valid document types and an invalid document type.

Abstract: A dissolving cell for the continuous processing of a sample, having a dissolving chamber enclosed by the sample, a seal and the body of the cell in combination with an anode. The cell includes a cathode and a D.C. power source for effecting the dissolution of the sample through an electrolyte conveyed to the chamber by an inlet terminal in open communication therewith. The dissolving cell includes a degasing shaft positioned between the dissolving chamber and outlet pipe. A first outlet pipe at the top of the degaser vents gases to a drain and a second outlet pipe communicating with the bottom of the degasser conveys electrolyte with sample to additional processing equipment.
