Abstract
Abstract Apparatus for the detection and analysis of particulate material carried in a fluid stream comprising a sampling device through which the fluid stream may be passed, said sampling device incorporating means for arresting and carrying an accumulation of particles restrained from flow in the fluid stream, means for directing ultra-violet radiation onto the sampling device at a location where the accumulation of particles results, and means whereby optical radiation analysis may be performed of the radiation emitted by the accumulation of particles consequent upon their excitation by the ultra-violet radiation means.

Claim 1
Independent Claim
102 words
An apparatus for the detection analysis of particulate material carried in a fluid cooling stream of a dynamo-electric machine, comprising: an at least partially transparent sampling means through which the fluid cooling stream may be passed; said sampling means incorporating removable filter means for arresting an accumulation of particles restrained from flow in the fluid stream; means for directing ultra-violet radiation onto said removable filter means at a location where the accumulation of particles results; and spectrometer means whereby optical radiation analysis may be performed on radiation emitted by the accumulation of particles cconsequent upon their excitation by the ultra-violet radiation means.
