Abstract: 1,269,900. X-ray diaphragms. A. E. ATOVMIAN, V. I. GORDON, I. A. DAVYDOVA, A. B. LITVAN and B. P. MAZANKO. 16 July, 1970, No. 34444/70. Heading H5R. Aidiaphragm structure for the production of a radiation beam of adjustable dimensions from the shielded ionizing radiation source 3 includes pairs of shielding blocks 4, 5, ..., 14, 15 mounted one pair below another and movable towards one another to obturate the beam, and away from one another by amounts which increase with distance from the source 3 to provide a pyramidal exit passage for the radiation, together with an optical, simulator formed by a pair of lamps 34 mirror. 35, and adjustableopaque plates 36, ..., 39, permitting the production on a target of an illuminated area adjustable in size to correspond to that: over which irradiation is required, the adjustment of the simulator automatically adjusting the distance apart through which the blocks 4, ..., 15 may subsequently be moved, to ensure that the irradiated area corresponds to the illuminated area. Blocks 6, 7, 10, 11, 14 and 15 all have their ends chamfered at 45; degrees to the guide 16 along which they are displaceable, 6, 10 and 14 in. one direction, and 7, 11, and 15 in the opposite direction, by rotation of the hollow roller 18, the other blocks having their ends chamfered at 90 degrees to the chamfer of the above blocks, and being similarly displaceable in two sets by rotation of the hollow roller 19. Considering roller 18: pins 26, supported in arms 20, 21 and 22 secured to the roller, move in slots in members 27, 28 and 29 which are rigidly secured to blocks 6, 10 and 14-respectively, and displace the latter when the roller rotates, increasing distances of successive pins. from the roller axis ensuring corresponding increasing block displacements along line II, II. Blocks 7, 11 and 15 are displaced by pins 53, 54 and 55 respectively, which are mounted on a member 52, Figs. 2 and 3, pivotally secured by trunnions 50 and 51 to arms 48 and 49 mounted on the roller 18. In use, the plates 36, 37, 38 and 39 of the optical simulator are adjusted with the passage from source- 3' closed, by rotation of cylinders 40 and- 41 mounted within the rollers 18 and 19. Rotation of cylinders 40 and 41 also adjusts mechanical stop members or electric limit switches (not shown) to prevent movement apart of blocks 4, 5, ..., 15 beyond the positions corresponding to the desired irradiation area on the target. Movement of the rollers 59 and 60 over the curved surface of member 61 produces movement of blocks, 7, 11 and 15 equal and opposite to that of blocks 6, 10 and 14. The linear surface portionof member 61 ensures that when the blocks are closed to shut off the beam, as in Fig. 3, their abutting surfaces are displaced from the geometrical axisof the beam, to improve the shielding, by the rotation of member 52 about trunnions 50 and 51.

The weight coefficient generating circuit, Fig. 5, is fed with the output of the transversal equalizer at 21 and includes a multi-level detecting circuit 22 which compares the input amplitude with the nominal amplitude levels, i.e. Œ1, Œ2, Œ3, Œ4 and produces an output 1 or 0 depending on the input level being above or below the nearest nominal level. In addition the input amplitude at 21 is fed to a polarity detector 24 which produces a 1 or 0 according as the polarity of the input signal is positive or negative. The two outputs are correlated by Exclusive OR gate OR 0  to increment gain adjuster G 0  and are also fed to shift registers SR1 and SR2 to feed further Exclusive OR gates to be cross-correlated at various different delays to increment the gain adjusters G -n  to G xn .

Abstract: 1315385 Photographic silver dye-bleach process CIBA GEIGY A G 17 July 1970 [25 July 1969] 34765/70 Heading G2C A photographic silver dye-bleach process, comprises exposing imagewize a photographic material comprising a support, at least one silver halide emulsion layer containing a diffusion resistant bleachable image dyestuff and adjacent to this layer on the side remote from the support silver halide emulsion layer free of image dyestuff, the sensitivity of which latter layer is at least as high as that of the layer containing dyestuff, and processing in the presence of a dyebleaching catalyst to give a colour image, the colour image being produced exclusively through image dyestuffs present in the material prior to the exposure. The sensitivities of the layers are measured in the absorbing regions of the dyestuff in the dyestuff containing layer. The sensitivities of the silver halide emulsion layers may be chosen so as to improve the linearity of the correspondihg colour gradation curve. The layer containing the image dyestuff and (or the adjacent layer which is free of image dyestuff may be optically sensitized. These layers may be optically sensitized with the same sensitizer. The layer which is free of image dyestuff may contain 10- 100% the amount of silver halide in the layer containing the image dyestuff. The dye-bleaching catalyst may be pyrazine, quinoxaline or phenazine and may be in a layer of the material, the dye-bleach bath or a pre-dye-bleach bath. The material may comprise at least two separate pairs of layers each comprising a layer containing the image dyestuff and an adjacent layer free of the image dyestuff on the side of the former layer remote from the support. The pairs of layers may be separated by an intermediate layer which may contain one or more filter dyestuffs, UV absorbers and/or oxidizing agents. Since the colourless silver halide emulsion layer lies on the side of the dyestuff containing layer remote from the support (i.e. on exposure, the side facing the light source), the colourless layer does not suffer optical desensitization by the image dyestuff layer.
