TL;DR: A semi-automatic torque transmitting gearbox for a vehicle consisting of an input member, first and second shafts co-axial with that member, a layshaft, gearing interposed between the input member and the layhaft and including freewheel means for permitting the layshft to rotate faster than it can be driven by a member through that gearing as discussed by the authors.
Abstract: A semi-automatic torque transmitting gearbox for a vehicle comprises an input member, first and second shafts co-axial with that member, a layshaft, gearing interposed between the input member and the layshaft and including freewheel means for permitting the layshaft to rotate faster than it can be driven by the input member through that gearing, gearing interposed between the first co-axial shaft and the layshaft which is of lower ratio than the first mentioned gearing, gearing interposed between the second co-axial shaft and the layshaft and including a disengagable clutch for positively connecting those shafts together via that gearing, a disengagable clutch for positively connecting together the first and second co-axial shafts, freewheel means for permitting the input member to rotate faster than the first co-axial shaft, and a disengagable clutch for positively connecting together the input member and the first coaxial shaft.

TL;DR: In this article, an investigation on the carbonisation of wool is presented, and arguments in favour of carbonising at different points in the processing sequence are considered in detail, and form the basis of the work reported in Part II.
Abstract: Investigations on the carbonising of wool are reviewed. Anomalous results have been obtained by a number of workers. The moisture content of wool material as it enters the dryer after the acid treatment can greatly affect the extent of damage. There are arguments in favour of carbonising at different points in the processing sequence. These are considered in detail, and form the basis of the work reported in Part II.

TL;DR: In this article, simultaneous differential thermal analysis (D.T.A.) and thermogravimetric analysis (T.G.A) for gels of wheat starch were used to measure the integral heat of dehydration, and it was shown that the energy required to disrupt the structure of the starch granules during gelation is greater than the energy released by increased starch hydration.
Abstract: Integral heats of dehydration have been measured by simultaneous differential thermal analysis (D.T.A.) and thermogravimetric analysis (T.G.A.) for gels of wheat starch. The results are interpreted on the basis that removal of water involves three structural changes: (a) Breakdown of starch-water interaction (endothermic); (b) Breakdown of water-water interaction (endothermic); (c) Increase in starch-starch interaction (exothermic). On balance, the overall process is endothermic.
It has also been shown qualitatively that the formation of gels from starch and water is an endothermic process. It is suggested that the energy required to disrupt the structure of the starch granules during gelation is greater than the energy released by increased starch hydration.
