Title: Improvements in or relating to photographic emulsions
IPC: G03C1/09
Filed: 1945-12-03
Abstract: 608,667. Photographic emulsions. ELLIOTT & SONS, Ltd., BARRETT, E. G. V., HOWE, D. J. T., and PARNELL, P. G. Dec. 3, 1945, No. 32616. [Class 98 (ii)] A small quantity of a water-insoluble gold compound in the form of a colloidal suspension is introduced to a gelatino-silver halide emulsion before or during final digestion to increase the sensitivity to light. The quantity is not intended to exceed the equivalent of 0.007 grams of metallic gold per litre of emulsion, and the silver halide concerned is principally silver bromide. A precipitating agent such as ammonia, pyridine, piperidine, triethanolamine, triethylamine, silver nitrate, thallous nitrate or lead acetate may be added to a gelatine sol containing sodium chloroaurate or potassium bromoaurate, or should the gold salt employed be a complex, cyanide, or thiocyanate, the precipitating agent may be an ammonium base or a salt of a metal which forms an insoluble cyanide or thiocyanate, and the resulting colloidal suspension of gold compound is set, shredded, washed to remove soluble salts, remelted and is then ready for addition to the emulsion. The emulsions should be made from normal gelatines containing sulphur compounds, otherwise, sulphur compounds' as described in Specification 539,355 should be added; and hardening agents, preservatives, stabilisers or optical sensitisers may be included. Six examples enumerate the improvement in speed, as compared with normal emulsions, which results. Specification 570,393 also is referred to.

Abstract: 1,107,450. Orienting closure caps. CONTINENTAL CAN CO. Inc. 20 July, 1966 [30 Sept., 1965], No. 32647/66. Heading B8S. Caps are thrown into hopper 12 (Fig. 2), are stirred by rotating plate 30, the caps entering the plate via holes 31 therein to fall on to rotating disc 25 provided with magnets 27 mounted therein. As the disc rotates the caps are attracted by the magnets and grip them flat against the disc in either of two orientations, open-face-againet or flat-face-against. As the caps travel upwards they are guided by flange 63 (Fig. 1), are directed into single line formation by and between guide bars 40, 45. Those caps which are positioned open-face-against are tipped by spring device 85 to enter shoot 100. Those caps which are positioned flat-face-against are carried past device 85, reversed, by curved walls 91, 92 and are carried upward once again by the disc 25 to be discharged into shoot 100. Assembly 120 (Fig. 1).-Caps are fed from shoot 100 past assembly 120 and finally discharged down shoot 15. However, if shoot 15 becomes full, excess caps are discharged back down shoot 114 to hopper 12 being directed thereto by shaped magnet 135, which normally carries them past the said shoot 114.

Abstract: 333,463. British Thomson-Houston Co., Ltd., (Assignees of Haughton, F. A.). Oct. 31, 1928, [Convention date]. Bending. - In making annular articles of semiplastic boards of fibrous material, the ends of a slab or plate of the material are first formed of varying cross section so that they can be given a uniform curvature in bending rolls, and the slab is then rolled into annular form. The maximum bending stress is midway between the lower rolls 10, 10<a>, so that by varying the cross-section of the ends of the blank the parts thereof are equally stressed by downward adjustment of the upper roll 11 so that the ends assume the same curvature as the rest of the blank and thus preliminary bending of the ends of the blank is rendered unnecessary. In order to avoid twisting during bending the ends of the blank, which are of varying crosssection for a length equal to half the distance between the lower rolls, are formed respectively with a V-shaped projection 15 and a V-shaped notch 13, each symmetrically arranged with respect to the longitudinal axes of the blank. The blank is first placed between the rolls and the roll 11 lowered to bend the end 15, Fig. 3. The rolls are then rotated and when the other end has reached the point of contact with the roll 10<a>, the roll 11 is further lowered to bend this end. The rolls are then rotated in the opposite direction to curve the blank still further. This cycle is repeated until the blank is formed into a complete circle with the ends engaging. The annular article is then rotated several times with a very slight adjustment of the roll 11.

The weld preparation groove may or may not include a workpiece gap. Parameters providing successful penetration beads are detailed with reference to Figs. 4a-4c, 5, 6j, 6k, 7m, 7n, and 8p (not shown). In such a process, the spacers 4 are of an organic substance having a non-hygroscopic property, and the burning of a fuse 8 positioned about 50 mm. ahead of each contact member 7 effects, through switching means 9, circuit breaking release of the contact member away from said assembly and energization of the following contact member to take up current feed. The flux may be a fused type, a sintered type or a mixture thereof. A grooved copper backing bar may be applied to the workpiece either directly or through glass tape.

Abstract: Polymers are obtained by reacting an anhydride or acid halide of an ethylenically unsaturated monocarboxylic acid having a chain of not more than six carbon atoms, with at least some of the phenolic hydroxy groups of a condensation product of a phenol and an aldehyde. The resulting ethylenic polymers may be cured by cross-linking, or may be copolymerized with ethylenically unsaturated monomeric material. The remaining phenolic hydroxy groups may be esterified or etherified with other materials.  In examples phenolformaldehyde condensates are esterified with acrylyl chloride, methacrylyl chloride, crotonyl chloride and acrylic anhydride, and in some examples the remaining hydroxyl groups are esterified with the reaction product of two moles of phenol with one mole of phosphorus oxychloride and with chlorinated benzoyl chloride; some of the polymers are cross-linked or co-polymerized with styrene, triallyl cyanurate and methyl methacrylate in the presence of a benzoyl peroxide catalyst.
