Title: Method of obtaining a smoking agent
IPC: A23L27/27
Filed: 1975-02-21
Abstract: An aromatising agent having smoke flavour is produced from tar or a smoke condensate, which were obtained by distillation of cellulose and/or lignin raw materials. However, phenols can also be used as starting materials which were extracted from the smoke condensate and have a molecular weight greater than 140. In this case, the tar or the condensate is extracted with an aqueous acid, such as sulphuric acid or phosphoric acid, in order to neutralise the nitrogen-containing bases. The product obtained is then distilled in two stages under reduced pressure in an inert gas atmosphere. The distillate of the second stage contains the aromatising agent. However, the distillation can be carried out first and only then after this the extraction with acid. Preferably, the aromatising agent obtained is additionally purified by adsorption. The said agent is suitable for imparting smoke aroma to foods.

Filed: 1924-03-24
Abstract: 213,289. Mairesse, G. G. U. M. March 24, 1923, [Convention date]. Embossing; bronzing and the like; stencils and stencilling ; transfers.-Relates to processes for embossing or marking textiles, leather, and other materials in colours, and consists in interposing between the material and a heated embossing roller or plate, a sheet of paper coated with a thin layer of paraffin wax or other fatty body mixed with suitable colouring-matter, the coated face being placed against the material. In addition, a fabric of loose texture may be arranged between the material to be marked and the coated sheet. The waxed paper f is attached to rolls g, i and the material c to be marked to rolls d, e, and the two webs pass between a pressure roller b and an embossing-roller a heated to 50-60‹ C. The wax melts at the places where it is subjected to pressure from the relief parts of the roller a and, together with the colour it contains, soaks into the material at these places, causing the threads of the material to adhere at the embossed parts and remain in such position When a fabric of loose texture such as tulle &c. is interposed, it absorbs the colour and gives to the design on the cloth an appearance similar to its texture. An ordinary stamping-machine can be adapted for carrying out the process by providing arms to carry the roller upon which the waxed paper is placed. The waxed paper f can afterwards be used to print the reverse pattern on a material by passing between two smoothfaced rollers. Specifications 23053/07, 9270/10, and 9271/10 are referred to.
