Title: Process for the production of plates for printing blocks
Inventor: HELL RUDOLF
IPC: B41M9/00
Filed: 1954-09-25
Abstract: 755,308. Local copying by scanning. PAUL, Ltd., K. S. Sept. 25, 1954, No. 27758/54. Drawings to Specification. Class 40 (3). In an arrangement for producing a plate to make a printing block in which an image is photo-electrically scanned to produce an electromechanically engraved image on one side of the plate which is scanned photo-electrically to derive an engraved image on the reverse side of the plate, the latter is subjected, prior to the first engraving operation, to a process in which it is formed with a thin surface layer of a colour different from that of the material of the plate and also of a different colour sensitivity so that the image engraved on the first side can be scanned by photo-electric means to produce the engraved image on the opposite side of the plate. For example, the plate may be formed of a white, or a white, yellow-tinted, thermoplastic material and provided with a blue surface layer so that a red-sensitive photo-electric means can be employed in the scanning of the first engraved surface to produce the image on the reverse surface. The blue layer may be obtained by immersing the plate in a bath solution of a dye, for example nigrosin blue in a liquid, such as acetone, which is also capable of acting as a solvent for the material of the plate.

Wireless tuning apparatus, adjustment devices for.-An indicating device for a wireless receiving apparatus has superimposed scale and index members, one being fixed and the other movable, the scale having spaced marking lines and the index member having an indicating line arranged to intersect some or all of the marking lines at an oblique angle. As shown in Fig. 1, the tuning- device is controlled by a rotary drum 2 carrying a cardboard strip or scale 4 which is marked with horizontal lines indicating frequency or wavelengths. Co-operating with this scale is a fixed celluloid or other transparent strip 6 having a triangular opening, the oblique lower edge of which serves as an indicating line. The point at which this edge intersects the corresponding line on the scale is marked for various frequencies and a calibration line marked on the scale. In a modification, the celluloid window is not provided with an aperture, but has an horizontal line marked with a short vertical cross line, their intersection serving as the indicating point. The lines on the scale are made oblique, if necessary, in order that each line may coincide with the indicating point at its own marked frequency.

Title: Improvements in dye mordanting processes for colouring photographic silver images
IPC: G03C5/48
Filed: 1934-09-29
Abstract: 449,679. Photographic dye toning processes. BREWSTER, P. D., 28, Gillespie Avenue, Fair Haven, New Jersey, U.S.A. Sept. 29, 1934, No. 27964. [Class 98 (ii)] A silver image in a gelatin layer is converted into a silver-iodide dye-mordant image by treating it first with a solution of an iodine compound or of a reagent including an iodine compound, preferably an iodine salt, which is absorbed by the gelatin ; and then with a gaseous or vaporous reagent which liberates, within the gelatin, iodine which converts the silver into a silver iodide dye mordant. The treating agents are preferably so chosen and proportioned that the iodine is continuously liberated at slow reaction velocity, to prevent spreading of the silver conversion product which would render the image unsharp. In a preferred form the layer is first impregnated with an alkaline iodide and an oxidizing agent (e.g. an alkaline iodate or nitrite), and is then treated with an acid gas or vapour (e.g. acetic acid) to liberate the iodine. Other examples of oxidizing agents and acid gases or vapours are specified. The bath containing the iodide and oxidizing agent may contain ammonia or other alkali to keep it free or nearly free of iodine. Iodine may be liberated in a layer impregnated with an iodine compound alone, e.g. an iodide, by the action of an acid oxidizing gas alone, such as chlorine, bromine, or an oxide of nitrogen. In. an example, the gelatin layer containing the silver image is first hardened with formaldehyde and then impregnated with a solution of potassium iodide, potassium iodate, and ammonia. After removing excess solution as by an air blast, the film is passed through an atmosphere containing an acid gas or vapour such as that of acetic acid until the image is bleached. The bleached laver is cleared of iodine with sodium bisulphite, washed, and dyed with a basic dye such as Malachite green or Rhodamine B. It may be necessary to dilute the gas as with air or other inert gas to prevent too rapid reaction. Reference is made to the Traube and Miller silver iodide dye-mordant toning processes.

Title: Potassium chloride extraction
Inventor: LANYON JOHN ARTHUR
IPC: C01D3/08
Filed: 1950-11-16
Abstract: Potassium chloride is extracted from underground deposits containing potassium and sodium chloride by introducing into the deposit an aqueous liquor which dissolves more potassium chloride than sodium chloride under the conditions existing in the deposit, withdrawing the resulting potassium chloride-enriched liquor and crystallizing potassium chloride therefrom.  The molten liquor resulting from the potassium chloride crystallization may be used to dissolve further salt after being heated, for example to 40-70 DEG C.  The liquor is preferably passed down the annulus between two concentric tubes, the enriched liquor passing up through the inner tubes.
