Abstract: 172,074. Naef, E. E. Aug. 23, 1920. Sulphur: carbon. - Sulphuretted hydrogen either alone, or mixed with other gases and with or without the presence of ammonia, is partially oxidized by means of highly active carbon, so as to obtain sulphur. Air or oxygen is supplied when necessary. Ammonium sulphide may be similarly treated in aqueous solution. The deposited sulphur is removed from the carbon by solvents. Such carbons as those, known under the registered Trade Marks " Eponite " or " Norit " may be used. Suitable carbon for use in the process can also be obtained by carbonization at low temperatures of materials such as wood, cocoa-nut and other shells, or finely divided anthracite, activated by air or steam at low temperature.

Title: Aniline-formaldehyde condensation products
Inventor: POWERS EUGENE LEROY
IPC: C08G12/08
Filed: 1964-06-12
Abstract: In the manufacture of methylene dianilines by condensing aniline with formaldehyde (or a substance yielding it in a molar ratio of 1.4-4: 1 in the presence of water and a Lewis acid catalyst, the content of 2,41-isomer relative to that of 4,41-isomer in the reaction product is raised by using a reaction mixture containing aniline in at least 4 times the weight of the water unless the process is effected continuously, in which event the weight of aniline must at least equal that of the water.  If the product is then converted into isocyanates by reaction with phosgene, an isocyanate composition having a reduced tendency to crystallize is obtained.  Specified catalysts for the aniline-formaldehyde condensation are hydrochloric, sulphuric, perchloric and hydrobromic acids, boron trifluoride, tin tetrachloride, phosphorus trichloride and oxychloride, thionyl chloride, aluminium chloride, iodine, bromine, benzoyl chloride, benzyl chloride and phthalyl chloride. The reaction is preferably effected continuously with sufficient agitation to cause turbulent flow of the reaction mixture.  The phosgenation may be effected in two stages at successively increasing temperatures and with further addition of phosgene between the tages.  A number of organic solvents in which the phosgenation may be effected are specified. Examples of the aniline-formaldehyde condensation are given.

In a binary register, Fig. 6, the beam in a stable state, digit 0, on target 56 switches to stable state, digit 1, on target 55 on coincidence between negative digit pulse on plate 49 and positive gating pulse on plate 48. The beam on target 53 follows the first beam due to cross-connections between targets 55, 56 and plates 44, 45, common to both beams. The state of the register is read by read-out pulse on plate 47 shifting the beam, or not, from target 53 to target 54. In a binary counter.
