Patent CA-2293690-A1 (CA)
Inventor: GAUDREAU JEAN ETIENNE
IPC: H04N5/04
Filed: 1998-05-05
Abstract: A decoding system (Fig. 4, 106) for extracting digital teletext and closed caption data from a video signal comprises a software implementation executed on a processor (Fig. 4, 408) which includes both a closed caption module (Fig. 5) and a teletext module (Fig. 8). The decoder system calls the closed caption module to detect a clock synchronization signal (Fig. 5, 502). Upon finding such signal, the closed caption module synchronizes to the signal (Fig. 5, 506), identifies a framing code (Fig. 5, 504), and extracts the closed caption data (Fig. 5, 506). Similarly, the decoder system may call the teletext module for the teletext lines, which also synchronizes using a teletext clock synchronization signal. When the clock synchronization signal is detected (Fig. 8, 802), the teletext module interpolates the incoming data to reconstruct the data signal (Fig. 8, 804). The data signal is then processed to normalize the amplitude (Fig. 8, 806) and reduce the "ghost" effects of signal echoes (Fig. 8, 808) prior to the slicing of the data signal (Fig. 8, 812). Hamming code error detection may be used to ensure the accuracy of the data (Fig. 8, 814).

Title: Process for coating and/or touching up coatings on metal surfaces
Inventor: LINDERT ANDREAS
IPC: C23C22/83
Filed: 1998-08-21
Abstract: Defects in an initial protective coating, particularly a conversion coating, on a metal substrate can be touched up so as to at least equal the original coating in corrosion protection by use of a dry-in-place aqueous acidic liquid comprising: fluorometallate anions; a component selected from the group consisting of phosphorus-containing inorganic oxyanions and phosphonate anions; and an oxidizing agent, preferably a mixture of hexavalent and trivalent chromium. Other preferred optional active ingredients include free fluoride ions, which stabilize the fluorometallate ions against the formation of precipitates, and a fluorinated surfactant. The same composition also forms an effective protective coating over previously uncoated metal, particularly aluminum. The compositions do not contain any substantial amount of silica, which has often been previously used in compositions for similar purposes.
