Fundamentals of the two-line method of emulsion calibration, in which the characteristic curve is derived from densities of two spectrum lines of constant relative intensity, photographed at different densitiy levels, are discussed. It has been found, that the principles of this method can be applied to the presentation of data obtained by any...

In a previous paper evidence was given that a step sector yields the same calibration curve for a photographic emulsion with either an intermittent light source or a continuous one, provided the emulsion has a negligible intermittency effect under the prevailing conditions. The data of that paper are now presented in a new way, based on that of...

The computation of efficiency differences of spectrum lines in step-sector spectra may be carried out by means of a special calculator according to Breckpot. The employment of this calculator is based on the assumption that the sector curves are linear and parallel. Curvature of sector curves, which is very common, introduces a systematic error,...

Nauwkeurige meting van de mechanische eigenschappen van de vrije verffilm maakt het in de eerste plaats mogelijk een voorspelling te doen over de duurzaamheid van het materiaal tegen barstvorming en glansverlies en opent in de tweede plaats perspectieven voor een beter inzicht in de werking van harsen en andere componenten, die gebruikt worden...

De experimentele methoden, die in beginsel bruikbaar zijn voor een bepaling van de mechanische eigenschappen van visco-elastische materialen, worden opgesomd en van deze worden een tweetal, namelijk de kruipproef en de gedempte trilling, uitvoeriger behandeld. Na een theoretische beschouwing van de principes van het kruipexperiment, waarbij in...

A description is given of a new one-bath method for continuous vat dyeing, which can be used in both pad—steam installations and Pad—Roll machines. Although at present the full details concerning the best procedure are not available, it is expected that the method developed for the continuous vat dyeing of relatively short lengths of cloth will...

The degradation of a series of synthetic‐fibre yarns was studied during a period of two years' exposure in the open. Yarns of the same type were exposed in the Xenotest under a variety of conditions and the fading of the SDC blue standards was similarly studied. Air temperature, black‐panel temperature, and humidity content were measured for...
