Title: Nitriles polymn using mixed nitrogen radical donors - to perform stepwise opening of the triple bond and polymn
Inventor: BEHNCKE HERMANN DR
IPC: C08G73/00
Filed: 1973-08-06
Abstract: Polymerisation of nitriles by opening the triple bond of the -C=N group, to a double bond -C=N- and consequent chain polymerisation, is achieved by use of a mixt. of catalysts consisting of N cpds. which liberate free N radicals at different initiating temps. These free radicals cause a stepwise bond-opening and chain formation to occur with cyanamides, e.g. dicyandiamide and its homologues. Even metal cyanides are susceptible to polymerisation of this kind. Since the permutations of conditions allow some cross-linking to occur, this can be esp. valuable in some cases, e.g. when polymerising as a surface coating on iron or steel. Polymerisations are carried out at temperatures ranging 100 degrees-1000 degrees C. with mixtures of nitrogen-radical donors in equivalent proportions and totalling 6-8% of the starting nitrile.

Title: Waste heat utilization combined with effluent distillation - and power generation by steam accumulators and steam engine exhaust condensation
Inventor: BORST ADOLF H
IPC: F01K3/18
Filed: 1975-04-12
Abstract: Waste heat from nuclear power stations, internal combustion engines or refuse incinerators is utilized for the treatment of industrial wastes and for the generation of power. The waste heat is introduced into a pressure vessel which is kept pressurized by a fluid tank at a higher level. Two steam accumulators feed a steam engine, the exhaust of which is passed through a coil in a tank feeding the pressure vessel, where it condenses. This eliminates waste of energy and complaints arising from discharging waste heat into rivers or the atmosphere. It can be used to supply drinking water and/or kinetic energy. It would help the oil producing countries where flare gases are burned as waste at present.
