Granted: 2013-11-19
Abstract: An integrated database and information server are provided that efficiently share information and tasks between various stored value programs. A server is configured to provide reusable objects and data structures that are suitably shared between various stored value products. A database at the server allows data to be shared between various programs so that each consumer associates with only one database record even though that consumer may use multiple shared value products. An exemplary common record for a consumer includes information relating to mailing addresses, preferred language, and the like.  By integrating modules and avoiding duplicate records, the record communicates with all stored value programs, so the information does not need to be repeatedly entered into the database. Moreover, new stored value products are quickly and easily created through selection and arrangement of various shared objects preferably maintained within the database.

Abstract: Disclosed is an improved conveyor. The invention provides an apparatus for conveying material having an elongated tube with an input end and a discharge end, an intake hopper having a front end secured to the input end of the tube and an endless belt for conveying material from the intake hopper to the discharge end of the tube. Mounted within the intake hopper is at least two augers positioned above the endless belt and external to the input end of the tube. The endless belt and the augers are driven with appropriate drive means. Rotation of the augers conveys granular material in the hopper toward the input end of the tube so as to flood feed the input end of the tube. The granular material is then carried to the discharge end of the tube by the belt. In addition, the invention provides for the mounting of the augers to permit adjustment of the location of the augers within the intake hopper as well as facilitating easy removal and replacement of the augers.      Further, the speed at which the augers are to be driven is also adjustable. The foregoing provides great flexibility with respect to different applications which the conveyor will be used for. The invention also provides for additional feed augers located toward the rear of the hopper and adapted for moving material from the sides of the hopper towards the center where it will be transported by the belt and augers to the input end of the tube.
