A computer implemented system for collating and presenting multi-format information in a user- desired format is envisaged. The system stores information related to clients along with additional their personal information in a transient repository. These stored items of information are usually in different formats which are then converted by the system into a format desired by the user of the system or into a pre-defined format. An input module present in the system accepts form a user, a desired output information format type and a client identifier corresponding to the client whose information needs to be collated. Based on the client identifier, the system converts the stored client related information in the desired format and then collates and displays the converted information for further processing.

The present invention provides a method for recovering waste hard alloy. According to the method, the waste hard alloy is used as an anode to directly perform electrolysis in a fused salt. The method comprises the following steps: 1) carrying out vacuum dehydration by using a fused salt dielectric; 2) by using the waste hard alloy as the anode and an inert electrode as the cathode, electrolyzing in the molten fused salt dielectric at 350-1000 ℃; and 3) separating and collecting the metal powder and fused salt dielectric after electrolysis. According to the technical solution of the present invention, tungsten and cobalt ions can directly dissolve out of the anode material-waste hard alloy to enter the fused salt dielectric, and deposit on the cathode plate under the driving action of the electrolysis voltage, thereby the metal powder granules are obtained. The tungsten, cobalt and other product materials obtained by electrolysis can be used as hard alloy materials, high-temperature structure materials, weapon materials, photocatalytic materials and the like, and are applicable to the fields of production processing, aerospace, war industry, environmental energy sources and the like. The method has the advantages of short technical process, no discharge of solid/liquid/gas waste and environmental friendliness.
