Patent IE-20060788-A1 (IE)
Title: An article comprising a PVC resin
Inventor: TOBIN JAMES
IPC: B29C47/02
Filed: 2006-10-26
Abstract: An article, for example, a fascia board is produced of PVC material by a co-extrusion process in which a substrate of sxpanded PVC is co-extruded with an external coloured PVC layer.  the external layer is produced from a composition of PVC resin, a stabiliser low in fatty acid soap content, for example, a tin based stabiliser, pigments low or devoid of carbon black, lubricant oils, as well as fillers and other minor ingredients. By avoiding or using a pigment low in carbon black content in the composition, the heat absorption by the article is significantly reduced over prior art PVC articles, and thus, the temperature to which the article is raided as a result of heat absorption is reduced, thereby minimising the effect of weathering on the article and thus enhancing its colour stability, dimensional stability and integrity against weathering, as well as avoiding white bloom.
Patent IE-20100614-A1 (IE)
Title: A flash memory device and control method
Inventor: RYAN CONOR MAURICE
IPC: G06F12/00
Filed: 2010-09-23
Abstract: The present invention is directed to a method for increasing the operational lifetime of a flash memory device, wherein, the method comprises varying the operating parameters of the flash memory device over the lifetime of the flash memory device over thr lifetime of the flash memory device. The advantage of providing a method which varies the operating parameters of a flash memory device is that the operational lifetime of the flash memory device will be increased. Relatively low voltages and relatively short voltage periods may be used initially to write to, read from and erase the flash cells in the flash memory device. As time passes, the flash cells in the flash memory device will begin to degrade and it will be necessary to increase the viltage and the period of the viltage applied to the flash memory device in order to ensure that the correct write, read and/or erase commands are carried out. The invention is also directed towards a flash memory device.  <Figure 1>
