TL;DR: In this article, the applicability of the temperature cross-correlation method to the measurement of liquid flow under steady and pulsating flow conditions is investigated and some further results to those published earlier are presented.
Abstract: The applicability of the temperature cross-correlation method to the measurement of liquid flow under steady and pulsating flow conditions is investigated and some further results to those published earlier are presented. The method is proved to be an accurate and reliable method of flow measurement in laminar flow of highly viscous liquids and turbulent flow of liquids under steady and pulsating flow conditions. In laminar flow, the measurement is dependent on the velocity profiles and hence sensitive to any disturbances which may distort the velocity profiles. In pulsating flow, the measurement is dependent on a parameter called the ‘Frequency parameter’ (KR). Only if KR <1 can the flow meter, calibrated for steady flow measurement, meter pulsating flow accurately. This condition is easily satisfied by highly viscous liquids. The measurement technique provides a linear output and an accuracy better than 3% can be achieved.

TL;DR: The results of a comparison of lightfastness testing using microscal equipment and normal light sources are discussed in this paper. But, despite some anomalous results obtained with other fibres, may be of great use as a cheap and easy means of light fastness testing.
Abstract: The results of a comparison of light-fastness testing using Microscal equipment and normal light sources are discussed. The new apparatus is satisfactory for determining the light fastness of dyes on wool and nylon and, despite some anomalous results obtained with other fibres, may be of great use as a cheap and easy means of light-fastness testing.

TL;DR: The fastness-to-water test, which is widely used on wool, has been examined and various factors involved have been assessed as mentioned in this paper, and the standard method must be strictly followed if reproducible results are to be obtained, and there is evidence that the pH at which the test is carried out should be specified.

Abstract: The education service of the United Kingdom is famous, or perhaps infamous, for its lack of national educational planning. For many years the further education service has been seeking a Further Education Council having the resources which the National Advisory Council on Education for Industry and Commerce has never had — namely to plan our future sensibly and professionally. The recent proposals of the Department of Education and Science (DES) regarding the setting up of the Technician Education Council (TEC) appear merely to play with the vast problems involved. It is seriously suggested that TEC should have a full‐time staff of one or perhaps two, and the that City and Guilds of London Institute (CGLI) can do the rest!

TL;DR: In this article, the authors show that low rates of rejection can be achieved in the dyeing of woollen fabrics by attention to factors such as fabric preparation, dye selection, dyeing method, machinery and supervision.
