“Darwin among the Machines‚” 46 years before Forster (whose story‚ “The Machine Stops‚” was published 107 years ago). It is hard to believe that two stories with a similar tone could have been written so long ago. What is even more incredible is that they both seem to relate to present day society. How could two people (both from a time when technology was in its infancy) could write stories that could have been written about our time or even in our near future? The concept that machines will surpass

modern carding machines have using the auto leveler still there can be some unevenness along the slivers. These two issues will affect the quality of the yarn. The draw frame machine is the last machine which can improve the yarn quality in the yarn manufacturing process. The tasks drafting and doubling are the objectives of the draw frame machine in order to improve the fiber orientation and sliver uniformity respectively. Removal of hooks and dust also can be carried out by the machine‚ at a significant

30 CHAPTER 5 TURBINES 5.1 Introduction Hydraulic turbines are the machines which use the energy of water and convert it to mechanical energy. The mechanical energy developed by a turbine is used in running an electric generator which is directly coupled to the shaft of the turbine. The electric generator thus develops electric power‚ which is known as hydro-electric power. 5.2 Elements of Hydraulic Power Plants Fig.5.1 General Layout of a Hydraulic Power Plant 31

Jocasta – one woman‚ two characters ‘The Infernal machine’ by Jean Cocteau is based on the Greek tragedy ‘Oedipus the King’ by Sophocles. This play is a modern adaptation‚ almost in the form of a farce‚ of the Greek tragedy.

The character of Jocasta‚ who was the wife and mother of Oedipus‚ is the most prominent
