A new freezing process for sinking shafts
Brief description of a process invented by Louis Koch. Gaseous carbonic acid, ammonia, or a mixture of dioxide of sulphur, is circulated in specially constructed tubes whereby a degree of cold of from 40 to 60 degrees Cent. is generated and communicated to the ground. (700 w.)
