Patent FR-2768582-A1 (FR)
Title: Transmission and reception process for broadcast digital information system
Inventor: REIBEL JEAN MICHEL
IPC: H04W88/02
Filed: 1997-09-17
Abstract: Packets are regrouped prior to transmission with the insertion of additional information packets. Successive frames are constructed by regrouping the data packets, and inserting, at the start of each packet, a frame packet row identification block.  Network signaling blocks are inserted in successive frames, with time spacing and short maximum duration which is less than that of a packet transmission. Each receiver tests (700,701) the presence or absence of a network signaling block corresponding to its relevant network.  It then synchronizes itself (71) on the successive occurrences of packet identification blocks corresponding to its group.

Inventor: PIET GERARD
IPC: C10G9/16
Filed: 1998-10-09
Abstract: Anti-coking coating deposition on a refractory alloy surface, involves oxygen and/or nitrogen plasma treatment and silicon oxide, nitride or oxynitride plasma assisted chemical vapor deposition (PACVD) in the same low frequency reactor. Coke deposition on a refractory alloy surface, in contact with hydrocarbon fluids, is prevented by a continuous two-stage surface treatment comprising low frequency oxygen and/or nitrogen gas plasma treatment and then low frequency PACVD (plasma-assisted CVD) of a silicon oxide, nitride or oxynitride layer from an organosilicon compound and oxygen or nitrogen. An Independent claim is also included for a refractory alloy component having a silicon oxynitride coating of formula SiOxNy,  x = greater than 1 to 3; y/x = 0.02 to 0.2. Preferred Features: Both stages employ a frequency of 2-450 kHz and a plasma of oxygen or nitrogen, together with organosilicon compound in the second stage. The process involves an initial stage of ion etching with an argon plasma and an optional final stage of coating oxidation or nitrogen plasma treatment. The second stage duration is sufficient to form a 0.1-100  mu m thick coating.
