摘要： An electronic security scheme and security system for a communications network facilitates the preventing of unauthorized access to an internal resource of an entity's internal computer system. A server includes a first set of ports for communication between an external communications network and the server. The server has a second set of ports for communications between an internal communications network and the server. A first firewall is interposed between the server and the external communications network. The first firewall is coupled to the first set of ports to provide at least one interconnection between the first set of ports and the external communications network. A second firewall is interposed between the server and the internal communications network. In one embodiment, the second firewall is coupled to the second set of ports to provide in a nonnegative integer number of interconnections between the second of set ports and the internal communications network.

摘要： Disclosed is a stud for a boiler or other high temperature application, such as a furnace. The stud is made of an iron aluminum alloy which comprises about 81 to 91 wt. % iron, about 8 to 13 wt. % aluminum, about 0.01 to 0.3 wt. % carbon, and zero to about 3 wt. % of a refractory metal and/or zero to about 1.5 wt. % zirconium. The studs are welded to a surface of a component of the boiler or furnace by arc or resistance welding. The aluminum of the iron aluminum alloy imparts good oxidation and sulfidation resistance to the studs. The alloy also has a good electrical resistance which makes the alloy especially useful for arc or resistance welding. The aluminum content acts as a getter to eliminate gas porosity in the resulting welds. The present invention is particularly useful for making boiler heat exchange surfaces or refractory covered surfaces wherein the studs function as refractory anchors.

摘要： The present invention resides in a method for making an internal combustion engine intake valve. An iron aluminum alloy, in the form of a coil or bar stock, is provided. The alloy comprises 76.05 to 90.15 weight percent iron, 9 to 13.3 weight percent aluminum, 0.05 to 0.35 weight percent carbon, and 0.5 to 3 weight percent of a refractory metal, and/or 0.3 to 1.5 weight percent of titanium in combination with, or in place of, the refractory metal. The coil or bar stock is extruded to a poppet valve preform configuration at a heading temperature in the range of 800.degree. to 2,000.degree. F. and a true strain of about 0.5 to 2.2. The preform configuration is then headed to a pre-machined configuration while maintaining the head of such preform at an effective heading temperature up to 2,200.degree. F., said heading being carried out at a true strain of about 1.4 to 2.3. The headed preform is then machined, to its machined configuration, without intermediate heat treatment, and then is coated by either nitriding or chrome plating. If desired, a hardenable steel tip can be welded to the valve stem, and then heat hardened.
