This paper reports the results of a study of water-vapour-sorption kinetics and the accompanying length changes observed in single wool fibres with the improved sorption vibroscope described in Part I of this series. Among the more interesting observ

Using a torsion pendulum, measurements have been made of the dynamic modulus of rigidity of wool fibers during the process of sorbing or desorbing water (from the vapor phase). Anomalous behavior is observed, with low values of rigidity which cannot

This paper describes tests of an approach procedure in which aircraft approach the airport on a radial track, circle the airport on an orbit and finally approach to land on another radial track in line with the runway. Ninety-six approaches were made

The method described provides glide-paths for climbing and descending aircraft by combining in a single instrument information from the barometric altimeter and radar distance measuring equipment. Preliminary flight tests have shown that the method p

The air-flow technique for the measurement of wool-fibre fineness has advantages over other methods because of its speed and convenience of testing. However, if the wool being tested is in the form of washed corings from greasy bales or corings from

The increasing volume of yield-testing of greasy wool indicates the need for equipment that has a greater rate of handling samples and is more automatic than that employed in methods in current use. New washer equipment has been developed in which sa
