Title: An improved method for the production of pure phenols from lignite tar, shale tar and low temperature tars
IPC: C07C37/00
Filed: 1934-12-14
Abstract: Pure phenols are obtained from lignite tar, shale tar or low temperature tar by heating the tar oil to at least 300 DEG  C. during or prior to fractionation so as to effect a mild cracking, treating the oils with soda lye, oxidizing the lye solution and then passing steam through it while the temperature of the liquid is increased to about 105--120 DEG  C., so as to remove impurities, and finally recovering the pure phenols by acidifying the liquid. The oxidation may be effected by air or by sodium hypochlorite, and resinous byeproducts may be recovered.  In examples, tar oil derived from low temperature tars is fractionated, the distillate treated with sulphuric acid, and a solution of the product in aqueous caustic soda is oxidized, steamed, and then acidified to yield pure cresols and an asphaltic residue.  Specifications 355,445 and 363,330 are referred to.

Abstract: 722,749. Colour filters. PHILCO CORPORATION. July 1, 1952 [July 25, 1951], No. 16555/52. Drawings to Specification. Class '97 (1). [Also in Group XL (a)] An interference layer of varying thickness has at least one surface arranged partly to reflect and partly to transmit light, as by the application of a partly reflecting film. Both surfaces of the filter layer may have such films. In one form a partially transmitting layer of metal, e.g. silver or aluminium, is evaporated on to a glass support. A filter layer of magnesium fluoride or zinc sulphide is then applied by evaporation. By successive masking and evaporation a stepped surface is produced with three different thicknesses in different areas. Alternatively the support surface may be grooved, e.g. with grooves of V-shape each having unequal inclinations on the two sides so that when a filter layer of uniform thickness, as measured normally to the support surface at any point, is applied, its effective thickness, in the direction of transmission, is different in different areas. The filter layer is covered by a further metal layer. The filter layer may, alternatively, be of glass or plastic.
