Patent number: 10858291Abstract: Ceramic tiles may be prepared employing a process characterized by the addition to the ceramic raw materials of an aqueous slurry comprising a swellable clay of the smectite family, a binder and a water-soluble salt of a monovalent cation. The ceramic raw materials mixed and then subjected to wet grinding to produce a slip. The thus obtained slip is then subjected to spray drying.Type: GrantFiled: April 2, 2015Date of Patent: December 8, 2020Assignee: Lamberti SPAInventors: Stefano Crespi, Davide Ricco', Paolo Prampolini, Giovanni Floridi, Giuseppe Li Bassi

Patent number: 9973770Abstract: A near-real time encoding of a signal comprising at least a video signal is disclosed. The encoding comprises acquiring the video signal included in a linear stream, the linear stream comprising at least two contents without a logical distinction between them, dividing the video signal into at least a first segment and a second segment of respective preset durations, at least one of the segments being capable of containing at least a part of said two contents and comprising recomposing information, executing a first encoding of said first segment using an off-line encoding to obtain a first encoded segment, executing a second encoding of said second segment using an off-line encoding to obtain a second encoded segment, said second encoding being executed at least partially in parallel with the first encoding, recomposing, using said recomposing information, said first and second encoded segments to obtain a continuous encoded signal.Type: GrantFiled: May 12, 2014Date of Patent: May 15, 2018Assignee: Sky Italia S.R.L.Inventors: Massimo Bertolotti, Stefano Crespi
