| 20090009285 | Authentication of Re-Presentable Items - A system for authenticating re-presentable items, such as currency notes and passports, comprises applying to each item a unique code, reading the code on presentation, and checking the code against a database, characterised in that at each check, the code is altered. | 01-08-2009 |
| 20090051485 | Methods and Apparatus for Product Authentication - A method for product authentication, comprising applying to the genuine products code on a label, the code being generated by an algorithm, which code is unique to a small sub-set of articles, preferably for a single such article, so that it can be assumed that any product on the market which either does not have a label or has a wrong label, or for which the label is otherwise accounted for, is counterfeit, the label being machine readable, such as a writeable RFID tag characterised in that the label comprises a machine-readable microcircuit to which a code can be written, and from which the written code can be read remotely. | 02-26-2009 |

| 20090146108 | Methods and Formulations for Producing Low Density Products - A method of preparing a low-density material and precursor for forming a low-density material is provided. An aqueous mixture of inorganic primary component and a blowing agent is formed, the mixture is dried and optionally ground to form an expandable precursor. Such a precursor is then fired with activation of the blowing agent being controlled such that it is activated within a predetermined optimal temperature range. Control of the blowing agent can be accomplished via a variety of means including appropriate distribution throughout the precursor, addition of a control agent into the precursor, or modification of the firing conditions such as oxygen deficient or fuel rich environment, plasma heating etc. | 06-11-2009 |
| 20090156385 | Manufacture and use of engineered carbide and nitride composites - Carbides and nitrides are provided containing a controlled amount of pre-determined diluents and methods for their manufacture and use are disclosed. The pre-determined diluents include at least one of the silica, silicon metal, carbon, alumina, boron oxide, alkaline earth oxides such as calcium oxide, magnesium oxide, alkali oxides such as sodium oxide, potassium oxide, iron oxide, titanium oxide, and other components typically present in glass, ceramics, or metals. The carbides and nitrides with pre-determined diluents are formed by optionally pyrolyzing a precursor material to form a carboneous mixture and heat treating the carboneous mixture for a pre-determined time and at an elevated temperature during which carbon and/or nitrogen reacts with silica in the mixture to form carbides and/or nitrides and controlled amounts of pre-determined diluents. The carbides and nitrides disclosed herein may be used as blowing agents in a glass, ceramic, or metal forming processes or for promoting dispersion of the carbides and nitrides throughout a glass, ceramic, or metal composite. | 06-18-2009 |
