Method For Inhibiting Stains On Aluminum Product Surfaces
Gary Nitowski - Leechburg PA, Raymond Colbert - Oakmont PA, Karl Wefers - Apollo PA, Daniel Roup - Bettendorf IA, Larry Wieserman - Apollo PA, Paul Ziman - Delmont PA,
A method for inhibiting the formation of stains, especailly water stains, on the exterior surface of aluminum alloy products. The method entails contacting the exterior surfaces of these products, particularly sheet or plate products, extrusions and/or forgings made from 5000 or 6000 Series aluminum alloys, with an organophosphonic or organophosphinic acid-derived material. Preferably, liquid forms of this material are added to an alcohol or water-based carrier solution, then sprayed, dipped, painted or rolled onto the surfaces of flat sheet or plate products to enhance their brightness. Other more complex shapes may be dipped into material baths.
Lubricant For Improved Surface Quality Of Cast Aluminum And Method
In an oxidation inhibiting lubricant composition suitable for use in the manufacture of aluminum alloys comprising lubricant base selected from the group consisting of solid lubricants, liquid lubricants, grease lubricants, emulsion lubricants, and dispersion lubricants, the improvement wherein the lubricant composition further comprises: an effective amount of a fluorine-containing passivating compound.
Method And Apparatus For Selective Presence Notification
Douglas Varney - Naperville IL, Raymond Colbert - Naperville IL,
A method and apparatus for reducing network resources from presence notification traffic. This invention assumes a standard presence architecture of presentities, watchers, and a presence server involved in pushing (notifying) watchers when a presentity's state changes. In addition, there exists a source of past communication data (or other data providing a means of prioritization) for a subscriber. The presence server determines, based upon the past communication data (or other prioritization data) of a subscriber, whether to notify about the presentity's state change immediately or to wait on notifying the watcher until either additional notify messages also need to be sent (and can be bundled in one message) or a guard timer expires. In this fashion, the presence information that the subscriber cares about is delivered in real time while the information that is less important to the subscriber consumes less network resources.
Combined Integrated Voice Data Terminal And Standalone Keyboard
This invention relates to methods for making a credit/debit card purchase without revealing the card number to the vendor of services or goods. The card holder is connected to a data base and provides the card number, plus holder identity verification, to the data base. The data base then verifies whether the card holder is authorized to incur the expense of the purchase, and, if so, provides an authorization indication or code to the vendor; the card number cannot be derived from the authorization information, thus helping to preserve the secrecy of the card number.
Separating Solid Particles From Used Lubricant Compositions

A process for separating oil from a lubricant composition containing solid particles. The contaminated lubricant composition is mixed with liquid or supercritical CO. sub. 2 before the lubricant composition and CO. sub. 2 mixture is filtered through a filter medium. The CO. sub. 2 is then evaporated, leaving an oil residue. Mixing the lubricant composition with CO. sub. 2 before filtration prevents the filter medium from being blinded by solid particles.
