Abstract: PCT No. PCT/GB92/00143 Sec. 371 Date Sep. 17, 1992 Sec. 102(e) Date Sep. 17, 1992 PCT Filed Jan. 24, 1992 PCT Pub. No. WO92/13425 PCT Pub. Date Aug. 6, 1992.An assembler and splitter of a Weston PAL (W-PAL) video signal has filter functions F1, F2 at the assembler for the luminance and chrominance components and corresponding functions F3, F4 at the splitter. The transfer functions are defined as F1=(L2+L1)/2+(L2-L1)z-1/2, F2=-(H1-H2)/2+(H1+H2)z-1/2, F3=(L2-L1)/2+(L2+L1)z-1/2, F4=(H1+H2)/2-(H1-H2)z-1/2 and wherein H1 (f)=L2 (2fsc-f) and H2 (f)=L1 (2fsc-f). Thus the filters are non-sharp cut and are compatible with normal PAL.

Abstract: An apparatus for highly efficiently encoding digital signals by converting input digital signals into signals on a frequency axis in a blocked form, and encoding the input digital signals with a suitable number of assignment bits for each of said blocks to transmit them, wherein the input digital signals are subjected to the orthogonal conversion and are divided by a critical band, encoded with a suitable number of assignment bits based on an allowable noise level, and are subjected to the floating processing. When the floating processing is to be carried out by a plurality of small blocks of a band narrower than the critical band, information of word length of a small block is transmitted out of the small blocks in the critical bands, in order to reduce the bit number for the word length and to compress the bits. Moreover, when the floating processing is to be carried out by small blocks of bands narrower than the critical bands, allowable noise level and information of word length of a small block are transmitted for each of the critical bands instead of transmitting the floating coefficient for each of the critical bands, in order to decrease the number of transmission bits and to highly compress the bits. When the floating processing is to be carried out by small blocks of bands narrower than the critical bands, furthermore, information of a word length corresponding to the number of assignment bits is transmitted, and information related to allowable noise level whose designated range is deviated toward the lower side from the signal level range within the critical band by a predetermined amount of level, is obtained through a quantization table and is transmitted instead of transmitting the floating coefficient, in order to more highly compress the bits. <IMAGE>

Abstract: The present invention relates to the conjugate of a titanium dioxide nanomaterial and nanoparticulate (1-100 nm) herbal and/or fruit extracts, synthesized by means of impregnation, using titanium dioxide as support, to which are adsorbed organic functional groups, inorganic radicals and plant extracts that confer thereon the property of being an anti-microbial agent with a high disinfectant and antiseptic power, removing bacteria, fungi, mycobacteria, spores, mycobacteria, protozoa and viruses. This invention is a solid nanomaterial in liquid suspension. Said material is prepared by means of impregnation to disperse the functional groups and the extract particles, with control of the temperature to stabilize the interactions within the network of the support. The virucidal, bactericidal, fungicidal, mycobactericidal, mycoplasmicidal, antiprotozoal and sporicidal activity of the nanoparticulate biomaterial depends on the particle size of the support oxide, the functionalization and the
