Title: Improvements in or relating to colloid silver halide photographic emulsions
IPC: G03C1/10
Filed: 1946-01-23
Abstract: 607,005. Photographic emulsions. DU PONT DE NEMOURS & CO., E. I. Jan. 23, 1946, No. 2238. Convention date, Jan. 25, 1945. [Class 98 (ii)] A colloid silver-halide photographic emulsion contains a condensation product of an aliphatic aldehyde with ammonia or a primary amine. An overall increase in speed is thereby given. Products of formaldehyde, acetaldehyde, n-propionaldehyde, butyraldehyde, secondary butyraldehyde or crotonaldehyde with ammonia, methylamine, ethylamine, n-butylamine, aniline, o-, m- or p-toluidine, alpha- and #-naphthylamine or p-phenylenediamine may be used, and they may be added at any stage in the preparation of the emulsion, or even associated therewith by impregnation after formation of layers. Preferably, they are added before digestion, since ageing increases the beneficial results. The condensation products may be used in conjunction with known sensitizers, fog inhibitors, emulsion stabilizers and sensitizing dyes in gelatin or other binding agents, and many of these various ingredients are specified. Ten examples indicate methods of production of the condensation products, the incorporation of them into emulsions, and the relative speed increase which results. Specifications 263,517, 263,853 and 265,931, [all in Class 2 (iii)], are referred to.

Title: Manufacture of chromiferous dyestuffs
IPC: C09B45/01
Filed: 1934-01-24
Abstract: Azo dyes, chromium compounds of; acid wool dyes, dyeing with.--Chromiferous azo dyestuffs are obtained by treating, in presence of a soluble salt of an organic acid, an azo dyestuff of the general formula HO--R1--N = N--R2, wherein R1 is a sulphonated naphthalene residue, R2 is a naphthol residue and the hydroxyl group of the residue R1 is in o-position to the azo bridge, with an agent yielding chromium used in such proportion that there is less than one atomic proportion of chromium for each chromable group in the dyestuff molecule.  The products give fast level blue to black shades on animal fibres, e.g. wool or silk.  The treatment may be effected in an open vessel or under pressure and with or without further additions such as an inorganic salt or organic or inorganic acid, in neutral or acid medium.  Specified agents yielding chromium are the chloride, fluoride, sulphate, sulphite, acetate, formate, oxalate and benzenesulphonate or mixtures thereof.  Specified soluble salts of organic acids are sodium, potassium or ammonium formate, acetate, propionate, oxalate, succinate, malonate, hexahydrobenzoate, hexahydrophthalate, o -benzylsulphonate, N-o -methylsulphonates and the corresponding salts of amino-, oxy- and aminooxy-acids, halogenated or nitrated acids, oxamino - acids, aminosulphonic acids of the benzene, naphthalene or anthracene series aminonaphtholsulphonic acids, benzoic and phthalic acids, oxybenzoic sulphosalicylic, sulphoaminosalicylic and sulphophthalic acids.  The following examples are specified: (1) 46,1 parts by weight of the azo dyestuff from nitrated 1 : 2-diazonaphthol-4-sulphonic acid and 2-naphthol are boiled for 5 hours under reflux with a solution containing caustic soda, sodium formate and chromium fluoride corresponding to 5,32 parts of Cr2O3 and the solution is evaporated in vacuo; the product dyes wool fast black tints from a bath containing an organic acid and sulphuric acid.  (2) 4,16 Parts of the azo dyestuff 2 : 1-aminonaphthol - 4 - sulphonic acid --> 2 - naphthol is boiled under reflux with a solution containing caustic soda, chromium formate corresponding to 0,42 part of Cr2O3, and the disodium salt of 1 - oxy - 4 - sulphobenzene - 2 - carboxylic acid, and the solution is filtered and concentrated and the dyestuff salted out; the product dyes wool fast marine blue tints.

Classes 17(1) and 17(2) A shoe upper which has been subjected at least to a preliminary tensioning over its last for example by being pulled over in conventional manner is slit at the lasting margin at a curved end portion of the shoe at a plurality of places spaced round it and an unwanted marginal portion of at least one of the layers of the upper materials is simultaneously trimmed away as the slitting progresses round the shoe end portion. A machine is provided generally similar in its construction and mode of operation to that described in Specification 680,933 having' an intermittently acting slitting knife (not shown), operated in time relation to feed rolls 1, 3 but having also a stationary but adjustable knife 5 having a cutting edge 15 formed on a curved portion 17 received in a peripheral groove 19 in the feed roll 3 to cut through the lining material without cutting into the outer layer of upper materials. The upper feed roll 1 also is recessed at 21 to provide clearance for the knife 5 when the rolles 1, 3 move together when there is no work present in the machine. The shoe is positioned in the machine relatively to the slitting knife by engaging its bottom with a plate 11 to determine the extent of the slits inward of the edge of the upper.

The cage 4 comprises an oval ring 13 secured to the edge of the diaphragm 14 and supporting a transparent tubular member 15 and perforated metal member 17 topped by an elliptical plate 11, the ring 13 sealing against a rubber ring 5 and the lower part of the diaphragm 14 bearing against a conical support 19 for the last 22; pleat guides (19a, 21a Fig. 2, not shown) for the diaphragm 14 prevent pleat formation near the upper 25. In use operation of valves 43 activates cylinder(s) 9 to close the cage 4 against ring 5, a low-vacuum in the chamber 45 tensioning the diaphragm 14; when the diaphragm 14 begins to cover the last 22 chamber 45 is pressurized to greater than atmospheric; when the cage 4 seals against ring 5. The region (50) Fig. 4, not shown below the membrane 14 is evacuated causing the lasting edge to fold over the insole, and a cylinder 26 locks the cage 4 to a plate 3. After a pre-determined time switching produces a low vacuum in chamber 45, relieves the vacuum below membrane 14, releases the lock cylinder 26 and activates cylinder(s) 9 to remove cage 4.

[Also in Division B7] In an aircraft launching and arresting apparatus (see Division B7), the reels 22A, 22B from which nylon tapes 20A, 20B are unwound during arresting, have each a brake 23L, 23R normally applied, prior to the aircraft landing, by static pressure from reservoir 13 pressurized by air pump 15, the fluid moving shuttle valve 19 to connect pipes 17 and 21L, 21R. On engagement of an aircraft with pendant 12 the reels are rotated to operate a pump 26 the pressure fluid from which moves shuttle valve 19 to connect pipes 43 and 21L, 21R, the braking pressure being dependent therefore on the velocity of the aircraft. A gear-box 49 driven from the reel shaft 27 turns a cam 51 once during an arrestment to operate valve 39 to either maintain a given pressure or to control the rate of decline of pressure in the system during landing. After completion of the landing, valves 55, 57 release the pressure fluid in the system and a motor 61 rewinds the tapes. In Figs. 7, 8, not shown, each reel brake is applied by fluid from separate pumps, one pump output being adjusted by a device 60 in accordance with changes in the tape tension due to changes in coefficient of friction of the disctype brake. In Fig. 12 a fluid friction brake has a vaned rotor 85 and vaned stators 77, liquid being supplied by a static tank and controlled by a cam 51 operating a valve as described above.

The terminals of the heating coil are connected to plug pins n surrounded by a sleeve v, pressed outwardly by a spring y, so that the razor must be held against the wall-socket the whole time during heating and cannot be inadvertently left therein. A disc o prevents the pins entering into their sockets to such an extent that they are retained therein, and the sleeve v may be closed at its outer end. In a modification of this plug, the spring-pressed sleeve v is replaced by a spring-pressed plunger arranged between short contact-pins. This subject-matter does not appear in the Specification as accepted.
