While “Industrie 4.0” had been a new and unknown term at the Hannover Fair in 2011, it has now, five years later, become one of the most widely used expressions in the context of production discussions in most industry branches. “What does Industrie 4.0 mean?” This question was asked quite frequently and, as a matter of fact, it could only be answered ambiguously in the past five years. But since every company has a different understanding of this buzz‐word, a general definition cannot be given at all.

The high temperature vacuum insulation system developed for the SNAP-21 10 watt Thermoelectric Power System has the dual purpose of supporting the 265pound biological shield while allowing minimum heat loss from the nuclear fuel. It is hermetically sealed and incorporates chemical getters to maintain a hard vacuum for five years. The biological radiation shield is supported by a thin walled neck tube at the generator end and three ball joint tension support rods at the other end. The insulation has demonstrated design ruggedness by withstanding vibration loadings of 3 'g' up to 50 Hz and 6 'g' shock loadings at 6 milliseconds duration (saw tooth peak) while at an operating temperature of 1285°F. A thermal heat loss for the insulation system of less than 50 watts has been achieved. f 2.0 10 10-ro Several small holes along near edge. No penetration Good cover pass-not much c rown but filled in.
