Patent GB-2056078-A (GB)
Title: Nuclear magnetic resonance systems
IPC: G01R33/561
Filed: 1980-07-07
Abstract: The invention is related to the so- called "echo-planar" method of NMR imaging. In that method a resonance is first excited in a slice and then two orthogonal gradients provided dispersion in the slice. One gradient is pulsed to space the frequencies of spins in adjacent strips allowing the other gradient to provide dispersion down the strips. It is now proposed to pulse the second gradient (Figure 3c) so that the dephasing down each strip is also in steps. The FID signals (Figure 3d) (including rephasing signals) for each distinct element so produced can then be put in an array and two- dimensionally Fourier transformed to yield the desired output for each element. <IMAGE>
Patent GB-2079480-A (GB)
Title: Heat-activated photographic and thermal recording processes employing precursor compounds
IPC: G03C1/42
Filed: 1980-07-08
Abstract: Various types of compounds needed in heat-activated photographic or thermal recording processes can be incorporated in sheet materials required for those processes as precursors of the general formula:   <IMAGE> wherein each of R<1> to R<4> is hydrogen or a substituent which allows the compound to decompose on heating to give products of the formulae:   <IMAGE> R<2> and R<3> possibly completing an unsubstituted or substituted heterocyclic nucleus containing the nitrogen atom to which they are attached and R<4> possibly including an unsubstituted or substituted fused-on ring, n is zero or unity, and X is =O or =S. Preferred compounds are those for which HNR<2>R<3> is a base, especially a secondary amine. These can be used in, for example, developer-incorporated silver halide materials. In processes involving dye formation by coupling, as in diazo type processes, compounds of Formula I can be prevented from coupling by blocking substituents. If R<4> is a hydroxyl, alkoxy or amino, group or an alkyl- or arylsulphonamido group para to the hydroxyl group shown, the compound of Formula I is a silver salt developing agent which on developing a silver salt to give a negative silver image releases a pattern of the compound of Formula III which corresponds to a direct positive image.
