Classified abstracts 86--98 37 : 39 : 41 86. Laboratory vacuum furnace with programmed control for growing silicon carbide crystals. (USSR) The control circuit ensures maintenance of temperature within 2 - 5 ° C of any set value in the range of 2350-2550°C. This is achieved by a comparison of the light emitted by the wall of the heater with that from a standard source (S.I-8 radiator). The power required to operate the furnace is 25 k W and the residual gas pressure is less than 10 5 tort. (USSR) I G Pichugin et al, PlantLab, (10), 1964, 1276-1278. 37 : 33 87.

A small v a c u u m chamber has been designed to enable investigations on structural changes taking place during creep of materials at high temperature and reduced ambient pressure. The chamber forms an accessory to the mechanical test installation 1P-4 M. By means of an oil vapour diffusion p u m p working in conjunction with a fore v a c u u m pump, a pressure of 10 3 torr is maintained in the chamber in which the material is undergoing creep at temperatures ranging from 300-1000°C.
