| 20110033664 | METHOD FOR PRODUCING AN OPTICALLY VARIABLE IMAGE CARRYING SHIM - The present invention relates to a method for producing a duplicated shim and the duplicated shim obtainable by the method. The duplicated (UV-cured) shim, independent of any carrying device (like a cylinder or belt), can be applied directly to the surface of the transfer roller (and impart the surface OVD structure into a clear lacquer) in a similar way to conventional nickel shims. | 02-10-2011 |

| 20100051142 | Directional solidification mould - A mould for use in directionally solidifying a component has a casting cavity including a single crystal selector spiral which is a helical passage having not less than 1¼ and not more than 1½ turns. | 03-04-2010 |
| 20100053596 | Crystallographic orientation measurement - A method is disclosed for measuring the crystallographic orientation of a component cast by a directional solidification process. The method comprises the steps of: illuminating at least a region of the component surface with substantially coherent light, measuring the mean angle and intensity of the light reflected from the component surface, and correlating said mean angle and intensity to the crystallographic orientation of the component. The method has been found to lend itself particularly well to automation. | 03-04-2010 |

| 20100207256 | SECURITY CHIP - A security chip is disclosed. The security chip includes: a substrate; an integrated circuit disposed on the substrate, the integrated circuit including circuit elements, circuit interconnect layers connecting the circuit elements together, and interlayer contacts supporting the circuit interconnect layers; a shield to at least partially shield the integrated circuit; and at least one lightwell in the shield and the integrated circuit, wherein each lightwell has a closed shape formed from parts of the circuit interconnect layers and interlayer contacts, wherein no exploitable voltage can be measured on the parts of the circuit interconnect layers and interlayer contacts, and wherein each lightwell forms a path for light to penetrate to the substrate preventing the light from reaching the circuit elements. Related apparatus and methods are also disclosed. | 08-19-2010 |
