ance of' cracks, which could be visuaily detected. The test results are tabu-
lated and show that the scale resistance of the blades is affected by a number
of structural and Lechiiical factors, in particular, by the surface condition.
Sand-blown blades withstand about 20 to 4o more cycles than blades that were
manually ground on a coarse emery stone. However, the sand-blown blades are

of' a deformable alloy are uy one order more scale-resistant. than cast biades.
It was established that the structural factors, determinii~6 the rigidity alid
temperature differences, exert a greater effect than defects of the scab type,
since in all cases the breakdown occurred not In the scabs but was located in
blade sections, determined by its design. The exceptionai effect of the surface
treatment upon scale re*istance was confirmed by tests made with flat specimens
whose surfaces were machined in different ways. There are 4 figures and 2
tables.

TEXT: The suitability of sheet materials for the manufacture of combustion
chambers was tested on a machine designed by the authors (Authorts Certificate
no. 898119). Thn machine makes it possible to check and Inspect the sheet materi-
aL as If under operational conditions. The specimen i:s heated by passing elec-
tric current and cooled by an air ';et. The thermal cycles are automatically con-
trolled and their number is registered by a special electric counter. The whole
heatIng-cooling cycle lasts from 30 sec to 2 minutes and more, and depends' on
the given conditions. One- and two- beveled specimens were tested at temperatures
ranging from 1100 to 900 0C. The specimens were made of alloys X20 H80 T 3

TEM Compacts which are the sum of a denumerable family of closed finite-
dimensional:submets, are denoted as,weakly denumerable-dimensional.
Theorem 1: In order that a compact X be weakly denumerable-dimensional, it
is necessary and sufficient that it in representable an inverse limit of a

The proof follows essentially the scheme of (Ref. I).
