Title: Improvements in or relating to photographic emulsions
IPC: G03C1/10
Filed: 1951-08-14
Abstract: 691,715. Photographic emulsions. DU PONT DE NEMOURS & CO., E. I. Aug. 14, 1951 [Sept. 6, 1950], No. 19181/51. Class 98 (ii). A photographic colloid silver halide emulsion has an enhanced light-sensitivity due to the presence of 0.097 to 0.91 per cent by weight based on the weight of silver of tetracarboxymethylethylenediamine or of an alkali metal, ammonium, or substituted ammonium salt thereof, e.g. a salt derived from diethylamine, trimethylamine, cyclohexylamine, tetraethyl- or tetramethyl - ammonium hydroxide, guanidine, diphenylguanidine, or biguanidine. The compound may be added during the initial precipitation of the silver halide, at the beginning, during, or end of ripening, or at some other point prior to the end of final digestion. The emulsion may also contain sensitizing cyanine or styryl dyes. In example 1, the sodium salt of tetracarboxymethylethylenediamine is added at the start of the digestion of a washed gelatino silver iodobromide emulsion. An orthochromatic sensitizing dye, chrome alum, potassium bromide, and saponin may be added, and the emulsion coated on a cellulose acetate support. Example 3 is similar, and in example 2, the emulsion is a silver chlorobromide emulsion, and the dye a panchromatic sensitizer, and the potassium bromide is replaced by potassium chloride. In the examples, comparisons are drawn between the speed, gamma, and fog values with and without the sodium salt of tetracarboxymethylethylenediamine, and in example 3 it is shown that addition of such salt after digestion is ineffective. The emulsion may contain a sulphur sensitizer, e.g. allylthiourea, a thiocyanate, sodium thiosulphate, or sodium hyposulphite. The emulsion binder may be gelatine, agar-agar, a polyglycuronic acid, zein, collodion, a substantially hydrolysed cellulose acetate, a cellulose glycollate or lactate, an alkali metal salt of a cellulose phthalate, polyvinyl alcohol, partially hydrolysed polyvinyl acetate (including vinyl acetatestyrene and vinyl acetate-maleic acid interpolymers), or a water-soluble polyvinyl acetal.

Abstract: 1461288 Fuel elements COMMISSARIAT A L'ENERGIE ATOMIQUE 3 May 1974 [4 May 1973] 19576/74 Heading G6C A fuel assembly comprises within a polygonal outer can 3 a cluster of fuel pins 4 retained parallel to one another at the junctions of a regular network with a bracing or support wire wound as a coarse helix between the two end plugs 5, 6 of each fuel pin 4. At least the non- peripheral fuel pins 4, i.e. those not in contact with the outer cam 3, belong to one of two types 1 and 2, one of the types (e.g. type 1 as in the Figure 5 embodiment) having a bracing or support wire 9 of diameter d 1  equal to the maximum spacing which exists between two adjacent fuel pins when in operation and the other type (e.g. type 2) having a bracing or support wire 11  of diameter d 2  less than the diameter d 1 . The cross-sections of the wires 9, 11 are indicated in Fig. 5 by 10, 12, respectively. The fuel pins 4 are clad in stainless steel sheaths, the end plugs 5, 6, wires 9, 11 and the outer can 3 also being of stainless steel. The above arrangement of two types of fuel pin with support wires of different diameter obviates some of the contact points otherwise occurring between adjacent fuel pins so as to facilitate longitudinal bending of the pins resulting from distortion and swelling of the pins during irradiation while making it impossible for adjacent pins to contact one another other than via support wires. As regards the peripheral fuel pins, either only those having a d 1 -diameter wire are placed at the periphery or, alternatively, both type fuel pins are placed peripherally in an arrangement similar to the fuel pins inside the cluster. Those fuel pins having a d 2 -diameter wire can then be arranged to bear on the can 3 only at the top plug 5, e.g. by using a large diameter plug, or the d 2 - diameter wires can be sheathed by tubular pieces of outside diameter d 1  at regular intervals so as to maintain a spacing d 1  between the outer can 3 and the peripheral fuel pins. Alternatively, each peripheral fuel pin has a d 2 -diameter wire with regular sheathing of the wire of some of the peripheral fuel pins by means of d 1 - diameter tubular members disposed opposite adjacent fuel pins so as to achieve a similar patterning to that specified for the inner fuel pins of the cluster. The cam 3 may be formed with longitudinal thickenings and/or longitudinal recesses on its inside surface.
