Patent GB-368433-A (GB)
Title: Process for printing vat dyestuffs on the animal fibre
Filed: 1930-12-19
Abstract: Animal fibres are printed with pastes containing vat dyes obtained by condensing arylido-o-aminoarylmercaptans with arylquinones, as described in Specification 265,641, [Class 2 (iii), Dyes &c.], together with triethanolamine and a reducing agent, and the prints are developed by a short steaming process followed by a treatment in an oxidizing bath.  Ammonia or an organic derivative thereof, and glucose, are advantageously added to the printing pastes.  Instead of the vat dyes themselves, their leuco compounds may be employed.  The process may also be used for producing coloured discharges.  In examples, (1) wool, silk, or weighted silk is printed with a paste containing the dye made by condensing 5-m-chlorphenylamino-3-methyl-2 : 1-aminothiophenol with chloranil, glycerine, or ethylenethiodiglycol, British gum, triethanolamine, sodium phosphate, glucose, sodium hydrosulphite and ammonia, and the prints are dried, steamed and developed in a solution containing hydrogen peroxide and ammonia or acetic acid, or sodium perborate; the dye specified may be replaced by the dyes made by condensing 5 - p - tolylamino - 3 - methyl - 2 : 1-aminothiophenol, 5-p-tolylamino-3-methoxy-6-methyl-2 : 1-aminothiophenol, or 5-p-acetaminophenylamino-3-methyl - 2 : 1 - aminothiophenol, with chloranil, and (2) wool or silk dyed with Diamine scarlet B is printed with a paste made up as in example (1), with the further addition of sodium formaldehyde-sulphoxylate and zinc oxide, dried and further treated as in example (1); blue prints on a red ground are obtained.  Specifications 285,041, 302,252, and 320,978, [all in Class 15 (ii), Dyeing, Processes &c. for], also are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) is not restricted to the use of the dyes described in Specification 265,641, or to the use of triethanolamine, but covers generally a process of printing animal fibres with easily reducible vat dyes, the leuco compounds of which remain substantially unchanged in the printing colour and are comparatively slowly reoxidized, the process being carried out with less than the usual quantities of alkali or alkaline agents and reducing agents and the prints being developed by drying, steaming and subsequent treatment in an oxidizing bath.  In an additional example the following dyes are used, without the addition of triethanolamine to the printing pastes--the dyes obtained by condensing bromo-1-chloro-2 : 3-naphthisatin-a -chloride with 4-methoxy-1-naphthol, 3 : 2-naphthocarbazolequinone, the dye obtained by condensing 6-chlor-3-oxythionaphthene with 4-methyl-6-chlor-2 : 3-dihydro - 3 - ketothionaphthene-2 - (p - dimethylamino)-anil, Thioindigo red B, Brilliant indigo, and the dye obtained by condensing isatin-a -anilide with 1 : 2-pheno-5-oxynaphthocarbazole in the presence of acetic anhydride.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,109,327. Cameras. NIPPON KOGAKU K. K. Aug. 26, 1966 [Oct. 7, 1965], No. 38406/66. Heading G2A. In a camera 1, the film F is located against guide pins 6 by means of a lever 7 pivoted at 8. The lever is biased by a spring 9 so that a lug 7a at one end bears against the edge of film F. The other end 7b of the lever is visible from outside the camera, as for example by projecting into the field of the viewfinder system 4, 5. When no film is present, the lever is pivoted anticlockwise by spring 9, so that end 7b moves out of the field of view. By providing a notch T in the film Fig. 5 (not shown) the same result is achieved, thus giving a visible indication that the end of the film is approaching. When a door 2 is opened, to reload the camera, a plate 10 slides to the right under the action of a spring 12. This engages with lever 7 to pivot it out of contact with the film, so facilitating reloading. When the door 2 is closed again, plate 10 is pushed back out of engagement with lever 7, which accordingly can re-engage the film edge once more.

Abstract: 931,901. Sampling apparatus. BIRMINGHAM SMALL ARMS CO. Ltd. Feb. 9, 1962 [Nov. 9, 1960], No. 38410/60. Class 58. [Also in Group XXX] A device for taking a sample from bulk material on a moving conveyer belt comprises a sample collector 12 supported by means 14, 16 above the belt, and moans 17 for moving the collector at substantially uniform speed along a path inclined to the direction of movement of the belt, the arrangement being such that the angle of inclination and speed of the collector are so determined in relation to each other and to the speed of the belt that the movement of the collector relative to the material-carrying surface of the belt is at right angles to the direction of movement of the belt. As shown in Figs. 1 and 2, the collector, which has an open end forming cutting edges 13, and an open bottom, is attached to a pair of chains 14 passing over sprockets 15, 16, the chains being guided by a curved track 20 so that the collector follows the shape of the belt when it is loaded; the track is spring-loaded downwardly to maintain the collector in contact with the belt. The sample collected is deposited in a shoot 22. In the modification shown in Fig. 3, the collector is attached to one end of the pivoted lever 31, the other end of the lever being connected to the piston 37 of a ram 38 which may be actuated by fluid pressure or electrical or mechanical means. A roller 40 is mounted on the lever 31 and is urged into contact with a curved cam-surface 41 by a spring 35 so that, as the collector moves across the belt,.it is constrained to follow the curve of the belt. In order to ensure that the collector clears the material on the belt during its return stroke, the roller is forced, by the spring 35, to ride over a pivoted cam 43.
