Patent number: 11429739Abstract: A method and system that enables a data owner to write data in an encrypted manner to an immutable ledger, and yet still be able to grant read access to specific data elements, as they were written at particular moments in time, to a requesting party. Examples therefore provide a process for encryption of data onto an immutable ledger in a time indexed manner, together with a process by which a third party can request access to the data stored in the immutable ledger from the data owner, and the data owner can provide them with certain decryption keys that allow the third party to read the data directly from the immutable ledger, again based on time-indexed queries. The data the third party can read is restricted to specific elements only of the data written, and further restricted to within a time range or to a specific point in time.Type: GrantFiled: May 19, 2020Date of Patent: August 30, 2022Assignee: Ordnance Survey LimitedInventor: David Charles Alexander Stow

Patent number: 8727127Abstract: A screening apparatus includes beams and screen panels forming a broad screening surface. Each panel is mounted to a pair of beams along opposite side edges to bridge between two adjacent beams. The panels are mounted to an upwardly facing edge of the beams by elongate fixing members extending in the longitudinal direction of the beams. The fixing members engage opposite side edges of the panels and include a pair of projections that extend into openings provided in the edge of the beams. Each projection is engaged by a locking clip to prevent release from the openings. The openings into which the projections extend are of greater diameter than the outside diameter of the projections providing a loose fit within the openings, to allow movement of the fixing rails and the screen panels before the projections are engaged by a locking clip.Type: GrantFiled: August 10, 2012Date of Patent: May 20, 2014Assignee: Lettela Pty LimitedInventors: Raymond Maxwell Woodgate, Marc Raymond Woodgate, David Charles Alexander James Waller
