Patent GB-996396-A (GB)
Title: Treating glass
IPC: C03C1/00
Filed: 1963-07-04
Abstract: A glass melt with a low water content and which is free from carbon dioxide is formed by comminuting a devitrified glass or mixture of devitrified glasses, dehydrating and degasifying the comminuted mass under vacuum at a temperature below the melting point, and subsequently melting and homogenizing the mass in vacuo or in a protective dry gas atmosphere. The initial devitrification may be performed by melting the glass and subsequently heat-treating it. The comminution can be effected by introducing the glass melt or crystal cake into water with subsequent drying by heat.  The crystallized product is then finely ground.  During homogenization the melt may be stirred with dried gas, e.g. air or nitrogen.  The resulting glass has lower light absorption in a range above 2.80 m than untreated glass. Examples relate to (1) silicate glass, (2) calcium aluminate glass, (3) borate glass, with the following percentage compositions by weight: (1) 33.3 SiO2; 52.2 BaO; 14.2 TiO2; 0.3 As2O3.

Title: Improvements in cracking and hydrogenating hydrocarbons
IPC: C10G47/32
Filed: 1921-10-07
Abstract: In cracking and hydrogenating hydrocarbon oils by passing their vapours together with steam over heated carbon derived from shale, wood, peat or other vegetable or animal matter, the gases from the condenser are freed from sulphuretted hydrogen and preferably also from carbon dioxide and passed together with oil vapours and steam through the retort.  Carbon dioxide may be removed by passage through slaked lime, and sulphuretted hydrogen by means of hydrated oxide of iron.  Vapours from high-boiling oils and those from low-boiling oils are passed alternately through the retort so that carbon deposited from the high-boiling oils is used up during treatment of low-boiling oils.
