Title: Electroslag melting for casting mfr - used to make large, one-piece stainless steel castings for energy applications
IPC: B22D23/10
Filed: 1973-08-24

Title: High molecular weight hydroxy-terminated polycarbonates - from thiodiglycol and phosphene or chlorocarbonate esters by interfacial reaction
IPC: C08G64/26
Filed: 1977-02-10
Abstract: Polycarbonates are prepd. by reacting divalent alcohols made up wholly or partly of thiodiglycol with COCl2 or chlorocarboric esters of divalent alcohols and/or phenols by phase interface reactor using conc. aqs. alkali soln. as HCl scavenger, in the presence of inert solvents.
