Abstract: 1366724 Colour image reproduction ITEK CORP 7 March 1972 [26 March 1971] 10502/72 Heading H4F [Also in Division B6] To assist an artist in the creation of an original painting of a colour image, e.g. a colour photograph, discrete areas of the surface to be painted are provided with designations, e.g. numbers, corresponding to the paint colour to be applied to those areas, i.e., a "paint-by-number" sursurface is produced. To further assist the artist an outline of distinguishable objects in the image may also be produced on the surface to be painted, a density gradient detector being employed. Reference is also made to the creation of ceramic mosaics, dyed rugs, and decorative stitching or needlework patterns. Initially boundaries of colour domains in a given colorimetric system are selected and given distinct designations, and a palette of paints corresponding to these colour domains is provided. The colour image to be copied is then analysed to establish the co-ordinate positions of the colours present in each portion thereof, and in response thereto the designation for the paint colour representing the colour domain that encompasses the colour co-ordinate position of the analysed colour is applied to the paint receiving surface in the geometrically corresponding portion of the image. The colour domains specifically comprise volumes in a three-dimensional colorimetric system, e.g. a tristimulus system or brightness, hue and saturation system. The diagrammed surface bearing the paint colour designations may be used as a guide to create coloured renderings on an auxiliary surface, e.g. by optical projection on to a glass window or wall, or by employing printing techniques.

Title: Improvements in or relating to the preparation of 2-sulfanilamidopyrazine
IPC: C07D241/22
Filed: 1945-04-30
Abstract: 2-Sulphanilamidopyrazine is prepared by reacting sulphanilamide, a halopyrazine and an acid-binding substance such as an alkali metal carbonate or bicarbonate.  Temperatures within the range 125 DEG  to 175 DEG  C. are preferred.  In an example, chloropyrazine, sulphanilamide and potassium carbonate are stirred and heated to 130 DEG  C. under reflux conditions until the mixture thickens and the temperature rises to 145-150 DEG  C.  Unreacted chloropyrazine is then recovered by steam distillation, and excess sulphanilamide crystallized out by acidifying to pH 8.0 to 9.5 and cooling to 10 DEG C.  The 2-sulphanilamidopyrazine is recovered from the solution by acidifying to pH 5, and purified by dissolving in alkali, treating with activated charcoal and reprecipitating with acid.  Halopyrazines may be prepared by the reaction of hydroxypyrazine with a mixture of phosphorus pentachloride and phosphorus oxychloride or by direct halogenation.
