Title: Improvements in the production of photographic silver images in blue-black tones using a methylol nitromethane
IPC: G03C1/35
Filed: 1942-07-06
Abstract: 560,253. Photographic silver images in blue - black tones. DU PONT DE NEMOURS & CO., E. I. July 6, 1942, No. 14752/43. Convention date, June 13, 1941. Divided out of 560,173. [Class 98 (ii)] Photographic silver images in blue-black tones are produced by developing' a photographic material containing a reducible silver salt image in the presence of a methylol nitromethane. The compound may be present in the material prior to exposure and development, e.g. in the emulsion, support (including the paper pulp or a size for the paper), substratum, antistatic, antiabrasion, baryta, backing, or protective layer, or may be incorporated in the developer. The compound may also be incorporated by bathing the material in a solution thereof prior to development. After incorporation of the compound, the material may be aged at from 65 to 140‹ F. with high humidity. The tone obtained varies with the halide ratio of the emulsion, the degree of hardness of the emulsion, the developer, the particular compound, and the sensitizing dye. Lesser quantities are needed if the material is aged. Compounds specified are monomethylol nitromethane, dimethylol nitromethane, and trimethylol nitromethane. In example 1, trimethylol nitromethane is added to a gelatino silver chlorobromide emulsion and the emulsion is coated on paper and kept at 130‹ F. for 8 hours. In example 2, trimethylol nitromethane is added to a gelatino silver halide emulsion, which is coated on a base, dried, and maintained at 120‹ F. for 14 hours.. In example 3, trimethylol nitromethane is added to a substratum solution, which is coated on a film support, followed by a fine-grain silver halide emulsion. The film is aged for 1 week at slightly elevated temperatures. Other emulsion binders, e.g. cellulose derivatives, regenerated cellulose, synthetic resins, agar-agar, albumens, and gums, may be used. The sensitizing dyes employed may be cyanine, carbocyanine, pseudocyanine, kryptocyanine, neocyanine, merocyanine, styryl, cyazine, or rhodanine dyes, including both salts and bases. Desensitizing agents, fog inhibitors, emulsion stabilizers, hardeners, and wetting agents (e.g. sodium higher alkyl sulphonates and sulphates, and saponine) may also be incorporated. The compounds are useful with kinematographic, lithographic, radiographic, camera, and stripping films and printing papers. The Specification as open to inspection under Sect. 91 refers also to the use of substituted monomethylol and dimethylol nitromethanes. This subject-matter does not appear in the Specification as accepted.

Filed: 1949-06-07
Abstract: 661,073. Centrifugal casting-machines. WUETIG, F. H., June 7, 1949, No. 15170/49. Class 83 (i). Extracting castings.-A strip of metal is made by casting molten metal into a centrifugal mould 1 provided with a spiral groove 2 and then removing the casting by giving the mould a spiral movement relative to a fixed stripper. The metal is poured by means of a trough 36 .arranged within the mould and tilted by gearing 40 and a motor 42, slag being retained by a roller 60, Fig. 2, mounted eccentrically at 62 and secured in adjusted position by screws 64. The groove 2 may have any desired form and the ends of the mould 1 have closing rings 32, 33 of which 33 is removed after casting. For centrifuging the mould is rotated by a belt 15 and motor 17 and for stripping by a gear 19 moved axially to engage a toothed ring 18, on the mould, and 28, on a nut engaging a fixed screw 29. When the ring 33 has been removed and the gear 19 moved to the right, the end of the strip is bent away from the mould and then the motor 27 is started, thus causing the mould to move to the right and rotate so that the stripper 46 follows the groove 2 and the strip passes along a guide 47, over a tongue 49 and into rolls 48 which feed it to a furnace for equalizing or reheating or for any further operation desired. To ensure that the stripper is aligned with the groove during this operation the mould may be indexed, before the gear 19 is moved to the right, by a projection 54, Fig. 6, on the ring 32 and retractable stops 55, 59. Cooling means for the mould may be provided.

Title: Electrolytic protection system
IPC: C23F13/04
Filed: 1959-05-05
Abstract: 910,460. Automatic control systems for cathodic protection arrangements. SABINS, R. C. May 5, 1959 [May 9, 1958; June 2, 1958], No. 15338/59. Class 38 (4). In a system for the cathodic protection of a ship's hull in which current from an external source is passed between an anode and the hull, and the current is regulated in accordance with the output of a silver/silver chloride half cell mounted near the hull, the half cell is intermittently or continuously depolarized by current from another external source. In one embodiment, a rectifier 81 supplies direct current between an anode 14 and the hull 16. The output of the rectifier 81 is controlled by a saturable reactor 64 in turn controlled by the output of a photo-cell 37 via a self-saturating magnetic amplifier 39. The photo-cell 37 may be illuminated by a lamp 34 through a hole in the face of a millivoltmeter 26 connected between a selected silver/silver chloride half cell 21 and the hull. The meter 26 is adjusted by an external resistance (not shown) so that at the required potential between half cell and hull, the meter pointer obscures the photo-cell 37. Movement above this value is prevented by a stop. If the potential falls, the cell is illuminated and passes a greater current, which after amplification causes the full output of the rectifier 81 to be applied between anode 14 and hull. Four half cells 21 are provided and these are sequentially connected by a motordriven switch 23 to the control system meter 26, to an auxiliary depolarizing source 92, to an idle rest position, and to a potential recorder 103. In a modification, Fig. 3 (not shown), only one cell is provided and it is permanently connected to both the meter and, through a high resistance, to the depolarizing source. Specification 868,819 is referred to.

Title: Improvements in or relating to the preparation of chlor-substituted ethylene derivatives
IPC: C07C17/00
Filed: 1950-06-23
Abstract: Trichloro- and tetrachloro-ethylene are made by providing a gaseous stream containing chlorine and either ethylene dichloride or ethylene, the molar ratio of chlorine to the other reactant falling substantially within the range of 1.5 to 4, percolating the stream through a fluidized mass of finely divided surface-catalyst particles in a reaction zone at 300-500 DEG  C., the mass of particles being supported in the zone by the force of the motion of the stream and reaction products, and removing and separating the reaction products. Higher and lower boiling chlorinated ethylene by-products may be recycled.  Preferred molar proportions for the gas stream are 1.5-3, or more suitably 2.5 to 3, moles of chlorine per mole of ethylene dichloride or 3 to 4, or most suitably 3.5 to 3.8, moles of chlorine per mole of ethylene. Conventional surface-catalysts are listed.  The velocity of reactants is preferably 0.25-0.6 ft./sec. based on the volume of the reactor, the catalyst being preferably ground so that 75 per cent passes 100-200 mesh (U.S.A. units) with substantially not more than 5-10 per cent above or below this range.  In examples, in which a 6 ft. nickel tube of diameter 2 3/4 inches is the reactor (1) 0.26 lbs. of ethylene and 2.19 lbs. of chlorine are passed per hour through three litres of activated charcoal at 390-407 DEG  C., and (2) 1.1 lbs. of ethylene dichloride and 2 lbs. of chlorine are passed per hour through 1-3 litres of Fuller's earth at 411-418 DEG  C., products being isolated in both cases by fractional distillation and di-, tetra- and penta-chloroethane recycled with additional chlorine. A small quantity of hexachloroethane is formed in (1), but none in (2). Specification 513,947 is referred to.
