Abstract: A computerized system for augmenting data from a source database with data from a reference database to generate an augmented database that can be used for predictive modeling is disclosed. The present invention includes a method for using the Internet to obtain information, including, reading a data record stored in a field of data, searching a database for information describing the data record, condensing the information describing the data record into a value description, associating the value description with the data record, and augmenting the field of data with the value description associated with the data. The present invention also includes a computerized system for augmenting data from a source database with data from a reference database to generate an augmented database that can be used for predictive modeling and data mining to conduct searches of data in the augmented database.

Abstract: An improved stainless alloy has application in handling concentrated sulfuric acid. The alloy of the invention preferably comprises 23 to 33% chromium, more than 20% nickel, 6% or more of silicon, 0.2% to 0.4% nitrogen and minor amounts of molybdenum, copper, and tungsten with the balance iron. The alloy offers superior corrosion resistance by comparison with the standard stainless steels over the range from 90% sulfuric acid into the oleum range. The alloy is readily weldable and may be used in either cast or wrought form. After heat treating the alloy acquires a duplex structure which has a mixture of austenite and ferrite phases. The heat-treated alloy is ductile.

Abstract: A method and apparatus in a communications system for providing post call information to a caller using a data processing system within the communications system. The processes of the present invention are implemented in a data processing system within the communications system. A connection of the caller to the communications system is detected in which the caller is initiating a call for which post call charge information is desired. The post call charge information for the call is automatically identified in response to termination of the call by the caller. The post call charge information is automatically presented to the caller.

Abstract: A highly collimated light source is directed at a reflective surface such as a diffraction grating, the grating being moveable with time. Light reflected from the grating is projected onto a display surface such as a scone of a lamp or onto a wall or a display plate. The plate may be transparent so that the light display is transmitted through it to a display surface of frosted glass positioned on the other side thereof.

Abstract: A combination door handle and security locking system in which the conventional door latch is actuated by turning the five-sided head of an operating shaft with a special socket wrench. A hinge plate having a slot for a padlock bail and a flat index tab on its inner surface is rotated to cover the operating shaft head. The tab must fit against one side of the operating shaft head to allow the hinge plate to be fully closed so that a padlock can be inserted in the bail. The latching mechanism is designed so that this tab will fit against one side of the operating head when the door is fully latched, to thus prevent rotation of the latching mechanism. The free end of the hinge plate has an offset portion which serves both as a sleet hood for the padlock and as a handle for opening the door.
