Abstract: A method is used to fabricate a hot-rolled steel having a yield strength greater than 550 MPa and an impact toughness of at least 27 J at a temperature of -40° F. In one embodiment, the yield strength is greater than 690 MPa. The method includes melting steel to create melted steel. The melted steel is poured into a mold. The metal steel is continuously cast into a steel slab. The steel slab is heated to maintain a predetermined temperature. The steel slab is rolled to reduce the thickness to a predetermined thickness to create a hot-rolled steel sheet.

Abstract: The present invention provides a system and method which allows a primary instrument holder to allow limited and secure use of a payment instrument by a third party. The primary instrument holder is not required to communicate with the third party during a transaction and is not required to carry any specialized hardware to be notified of a transaction, authorize a transaction or deny authorization for a transaction. Pre-established business rules are used to determine the conditions under which the primary account holder is notified of a particular transaction. According to an illustrative embodiment of the present invention, a virtual payment instrument is provided to an authorized third party. The virtual payment instrument acts as a proxy to a primary payment instrument held by the primary instrument holder. The virtual payment instrument may be used by the third-party instead of the primary payment instrument that is held by the primary instrument holder.

Abstract: The present invention relates to a method of treating a glazing panel from an inside location. Moreover, the present invention relates to a method of treating glazing panels used in windows and patio doors. Initially, an orifice is formed on both the inside and outside panes on windows and on the side and outside frames of patio doors. Then, particulate matter such as dirt, dust, and mineral deposits are purged from the enclosed volume of the glazing panel by applying a cleaning solution via the orifice. Next, a valve is attached to the outside pane/frame to cover the orifice whereby the valve is designed to reduce the amount of precipitation or matter from entering while allowing air to exit the glazing panel. Finally, a seal is used to cover the orifice on the inside pane or side frame to ensure that the building air does not enter the interior of the glazing panel. The method can also be used to treat windows for high altitude transport, or to prevent explosion in the presence of intense heat.
