Title: Improvements in or relating to photographic printing methods and apparatus
IPC: G03B27/16
Filed: 1958-12-04
Abstract: 906,150. Applications of luminescence. UNITED STATES RADIUM CORPORATION, EUROPE. Dec. 4, 1958 [Oct. 10, 1958], No. 39153/58. Class 39 (1). [Also in Group XX] Apparatus for dodging photographic positive or negative prints comprises a U.V. source 16, a fluorescent layer 15 producing actinic light on excitation by U.V. light, a filter 19 for stopping U.V. light, a photographic negative 12, a lightsensitive emulsion 13 insensitive to I.R. light, a filter 18 passing only I.R. light, and an I.R. light source 17. For producing negative prints the order of the negative 12 and emulsion 13 is reversed. The I.R. light passing through the negative 12 produces a patterned quenching action on the light produced on the fluorescent layer 15 by the U.V. source 16 and thereby regulates the light passing from the layer 15 through the negative 12 to the emulsion 13. The fluorescent layer 15 and the negative 12 can be separated by a distance between a little more than zero, and approximately half an inch, e.g. about one-sixteenth of an inch. The fluorescent layer 15 is formed of material producing strong emission in the range of 4200-4400 Š, e.g. activated zinc sulphide. An exposure timer 20, Fig. 2, having a photo-cell 21 exposed to the output luminescence of the layer 15, is coupled both to the U.V. source 16 and the I.R. source 17. In order that the rays from the fluorescent layer 15 and the I.R. source 17 towards the negative 12 and emulsion 13 should be strictly parallel. A Fresnel lens system or parabolic reflectors can be used.

Title: Process for the regeneration of degraded solutions from a hydrogen peroxide synthesizing process
IPC: C01B15/023
Filed: 1958-12-05
Abstract: A degraded working solution of a quinone and/or quinol in a solvent, which has become degraded during the production of hydrogen peroxide involving the successive reduction, oxidation, and water extraction of a quinone in a cyclic process, is regenerated by heating the solution to at least 50 DEG C. in the presence of a hydrated amorphous sodium aluminium silicate having a composition corresponding to the formula Na2O .yAlO3 zSiO2, where y is from 0,56 to 3 and z is from 0,5 to 10.  Preferred temperatures in excess of 50 DEG C. are from 100 DEG C. to 200 DEG C., the use of higher temperatures by utilization of superatmospheric pressure being also referred to.  The working solution may comprise a quinone, examples being 2-ethyl-, 2-isopropyl-, 2-secondary butyl-, 2-tert. butyl, 2 secondary allyl-, and 1:2, 1:3, 1:4 or 2:7 dimethylanthraquinone, dissolved in such solvents as (i) 1-methylnaphthalene, benzene or trimethyl benzene and/or (ii) ketones, esters or alcohols, such as diisobutylcarbinol or methylcyclohexylacetate.  In operation, the working solution, and from which some of the solvent may be removed or, if a solvent mixture has been employed, from which one or more of the solvent constituents has been completely removed is taken from the process preferably immediately after extraction of the hydrogen peroxide, is subjected to regeneration and subsequently returned to the process.  Alternatively, a small portion, e.g. 1-10% of the total volume of working solution is continuously removed from the cycle, regenerated, and returned to the cycle.  A further aspect of the invention consists in adding sodium aluminium silicate in a concentration say 1-40% wt. of the circulating working solution and effecting regeneration, by subsequently heating to at least 50 DEG C., of solution from any stage of the process.
