Abstract: 663,020. Photographic emulsions. KODAK, Ltd. Nov. 18, 1949 [Nov. 18, 1948], No. 29567/49. Class 98 (ii). The speed of a light-sensitive silver halide emulsion is increased by the incorporation of a water-soluble formaldehyde sulphoxylate salt. The emulsion may also contain a sulphur sensitizer incorporated before, simultaneously with, or after the salt, a gold salt, and an optical sensitizing dye. The salt may be added during digestion of the emulsion, so that further digestion occurs after the addition. At least one emulsion layer of a colour photographic multilayer material may be so prepared. Examples are given illustrating, in conjunction with a table, the fog, gamma, and speed values obtained with emulsions peptized with a gelatine derivative as described in Specification 649,545 and formed with gelatine and polyvinyl alcohol binders, and containing no addition, sodium formaldehyde sulphoxylate, allyl thiourea, and sodium formaldehyde sulphoxylate plus allyl thiourea, and (using a gelatine binder) allyl thiourea plus potassium auric chloride and allyl thiourea plus both sodium formaldehyde sulphoxylate and potassium auric chloride. The increase in speed obtained with a sulphoxylate sensitizer plus a sulphur sensitizer is considerably greater than would be expected from the speed increases obtained by the use of the individual sensitizers. The emulsion binder may also be a copolymer of polyvinyl alcohol or a partially hydrolysed cellulose ester. Specification 235,211, [Class 98 (ii)], is referred to.

Title: Improvements relating to the manufacture of carbon black
Inventor: LOVING WILLIAM L
IPC: C09C1/50
Filed: 1950-12-06
Abstract: <PICT:0703360/III/1> In a process and apparatus for making carbon black as described in Specification 633,945, a fine spray or jet of atomized or vaporized hydrocarbon oil of a divergent conical formation is injected into the air-gas mixture substantially centrally with respect to the pattern of gas jets, and carbon black is collected from the combustion products.  Air passes from duct 20 to casing 13 through perforated baffle plate 21 and a nest of rectangular cell-like passages 23, and thence, between oval burner pipes 14 as separate parallel sheets.  Pipes 14 are supplied with hydrocarbon gas from header 16, which may be preheated to 800-1000 DEG F., and have orifices 15, so that the multiplicity of small jets of gas produced are arranged in rows between the air sheets and are directed and flow thereinto at such higher velocity than the air, e.g. at least twice that of the air, that a localized turbulent mixture of air and gas is produced under conditions of incomplete combustion.  The resultant air-gas mixture at say 2300-2500 DEG F. passes into refractory lined rectangular chamber 10, while oil, which may be preheated to 600-750 DEG F. is atomized by say air hydrocarbon gas, or steam from mixing nozzle 25 and passes through pipe 29 and tip 30 into the air-gas mixture.  The air may also be preheated to 900-1400 DEG F.  The cell-like passages 23 are each associated with orifices 15 so that equal volumes of air are directed to each orifice, and the air passing between the burner pipes 14 ensures that the air sheets are of substantially equal volume.  The hydrocarbon gas supplied to the burner pipes may be enriched with vaporised oil and various combinations of preheated or unpreheated hydrocarbon gas, enriched or not with hydrocarbon oil vapour, with preheated or unheated atomized or vaporized oil are exemplified.  More than one atomizing nozzle may be used replacing the central burner pipe (5 pipes).  Specification 654,822, [Group XI], also is referred to.
