Title: Bitumen composition
IPC: C08L95/00
Filed: 1979-04-25
Abstract: A bitumen composition comprises from 50 to 70% by weight of petroleum bitumen; from 20 to 30% by weight of ash asphaltite; and from 10 to 20% by weight of a selectively purified petroleum oil fraction extract. This composition may be produced by heating the extract to a temperature of from 40 to 80 DEG C mixing this with the ash asphaltite and heating the product to a temperature of from 180 to 240 DEG C; and finally mixing this mixture with the petroleum bitumen. The final composition has rheological properties, such as softening and brittleness temperature, that make the composition useful in asphalt concretes. Such asphalt concretes have a long life and can withstand both high and low temperatures.

Patent GB-2050589-A (GB)
Title: Drying carbon black
IPC: F26B25/00
Filed: 1980-05-08
Abstract: Carbon black pellets (22) from a wet pelleter (14) are passed through a rotating drum (20) surrounded by a heating enclosure (32), through which heating gases are passed, and are discharged from the outlet end (24) of the drum through a discharge passage (26). Air for drying the pellets is drawn in through the discharge passage, and from thence through the drum in counter-flow to the pellets. The air is exhausted from the inlet end (15) of the drum, and can be taken to a filter (50) where carbon black particles are separated. Thus, the drying air is kept separate from the heating gases, and the exhaust gas is relatively uncontaminated and free from condensate other than steam. In addition, the drying air, being preheated by the discharged pellets, cools the pellets ready for banging. <IMAGE>

Patent GB-2069474-A (GB)
Title: Process for Producing Hydrogen Fluoride
IPC: C01B25/22
Filed: 1981-02-12
Abstract: A method for producing hydrogen fluoride from fluoride-bearing ores, such as fluorospar and fluorapatite, comprises contacting a fluoride and phosphate-bearing raw material with excess fluorosulfonic acid to release hydrogen fluoride and volatile phosphorous compounds, separating said hydrogen fluoride and volatile phosphorous compounds from the excess fluorosulfonic acid and residual matter, separating hydrogen fluoride from the volatile phosphorous compounds and recovering same. The reaction is preferably carried out with the ore as a slurry in fluorosulfonic acid. The slurry is heated by the exothermic heat of the reaction to vaporize volatile phosphorous compounds and substantial quantities of hydrogen fluoride. Another feature provides for addition of calcium fluoride to the slurry to react with the byproduct sulfuric acid in the residual solids to eliminate the sulfuric acid recovery step in the process. Additionally, at least a portion of the hydrogen fluoride may be reacted with sulfur trioxide to form fluorosulfonic acid for makeup in the process.
