Patent CA-2460409-C (CA)
Title: Filtering apparatus
Inventor: BUCKETT JONATHAN
IPC: B01D33/073
Filed: 2002-09-10
Granted: 2011-11-29
Abstract: A liquid filtering apparatus for mounting in a housing defining an inlet and a drain. The liquid filtering apparatus is positioned in use to filter liquid flowing from the inlet (23) to the drain. The apparatus comprises a permeable screen (19) rotatable about a substantially horizontal axis and forming a barrier between the inlet and the drain. A rotatable wheel is disposed within the screen and coupled to the screen so that rotation of the wheel causes rotation of the screen. The wheel is defined by vanes (5-12) extending towards the screen so as to divide a space around which the screen is arranged into sections which are substantially isolated from each other except via the drain. A stationary baffle (13) is arranged adjacent a portion of the screen to prevent liquid from flowing into the wheel through that portion of the screen. The baffle is positioned such that water flows more readily into sections of the wheel on one side of a vertical plane through the rotation axis than the other sections. Thus the wheel is unbalanced by water retained in sections of the wheel so as to cause the wheel to rotate.

Title: Improvements in or relating to the copy protection of optical discs
Inventor: BASILE CARMEN LAURA
IPC: G11B20/00
Filed: 2005-05-19
Granted: 2011-08-16
Abstract: Subversive data has been incorporated in the content of an optical disc, such as a DVD, to prevent copying of the disc. To defeat such copy protection, devices to copy optical discs are now being controlled to only copy data referred to by selected program paths. Accordingly, it is proposed to provide copy protection for optical discs by introducing errors into redundant control data to frustrate access to content on the disc. For example, the errors may be inconsistencies in a Video Manager Information Table (VMGI) or in a Video Title Set Information Table (VTSI).
