Some context: James Watt  (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.
In 1776, the first engines were installed and working in commercial enterprises. These first engines were used to power pumps and produced only reciprocating motion to move the pump rods at the bottom of the shaft. The design was commercially successful, and for the next five years Watt was very busy installing more engines, mostly in Cornwall for pumping water out of mines.  These early engines were not manufactured by Boulton and Watt, but were made by others according to drawings made by Watt, who served in the role of consulting engineer. The erection of the engine and its shakedown was supervised by Watt, at first, and then by men in the firm's employ. These were large machines. The first, for example, had a cylinder with a diameter of some 50 inches and an overall height of about 24 feet, and required the construction of a dedicated building to house it. Boulton and Watt charged an annual payment, equal to one third of the value of the coal saved in comparison to a Newcomen engine performing the same work.  The field of application for the invention was greatly widened when Boulton urged Watt to convert the reciprocating motion of the piston to produce rotational power for grinding, weaving and milling. Although a crank seemed the obvious solution to the conversion Watt and Boulton were stymied by a patent for this, whose holder, James Pickard, and associates proposed to cross-license the external condenser. Watt adamantly opposed this and they circumvented the patent by their sun and planet gear in 1781.  Over the next six years, he made a number of other improvements and modifications to the steam engine. A double acting engine, in which the steam acted alternately on the two sides of the piston was one. He described methods for working the steam "expansively" (i.e., using steam at pressures well above atmospheric). A compound engine, which connected two or more engines was described. Two more patents were granted for these in 1781 and 1782. Numerous other improvements that made for easier manufacture and installation were continually implemented. One of these included the use of the steam indicator which produced an informative plot of the pressure in the cylinder against its volume, which he kept as a trade secret. Another important invention, one which Watt was most proud of, was the parallel motion which was essential in double-acting engines as it produced the straight line motion required for the cylinder rod and pump, from the connected rocking beam, whose end moves in a circular arc. This was patented in 1784. A throttle valve to control the power of the engine, and a centrifugal governor, patented in 1788, to keep it from "running away" were very important. These improvements taken together produced an engine which was up to five times as efficient in its use of fuel as the Newcomen engine.  Because of the danger of exploding boilers, which were in a very primitive stage of development, and the ongoing issues with leaks, Watt restricted his use of high pressure steam - all of his engines used steam at near atmospheric pressure.
What modifications were made?

Some context: Sutcliffe was born in Bingley in the West Riding of Yorkshire to a working-class family. He was given a Catholic upbringing by his parents, John William Sutcliffe and his wife Kathleen Frances (nee Coonan). Reportedly a loner, he left school aged fifteen and had a series of menial jobs, including two stints as a gravedigger in the 1960s. Between November 1971 and April 1973, Sutcliffe worked at the Baird Television factory on a packaging line.
An application by Sutcliffe for a minimum term to be set, offering the possibility of parole after that date if it is thought safe to release him, was heard by the High Court of Justice on 16 July 2010. The High Court decided that Sutcliffe will never be released. Mr Justice Mitting stated:  This was a campaign of murder which terrorised the population of a large part of Yorkshire for several years. The only explanation for it, on the jury's verdict, was anger, hatred and obsession. Apart from a terrorist outrage, it is difficult to conceive of circumstances in which one man could account for so many victims.  Psychological reports describing his mental state were taken into consideration, as was the severity of his crimes. Barring judicial decisions to the contrary, Sutcliffe will spend the rest of his life in Broadmoor Hospital. On 4 August 2010, a spokeswoman for the Judicial Communications Office confirmed that Sutcliffe had initiated an appeal against the decision.  The hearing for Sutcliffe's appeal against the ruling began on 30 November 2010 at the Court of Appeal. It was rejected on 14 January 2011. On 9 March 2011, the Court of Appeal rejected Sutcliffe's application for leave to appeal to the Supreme Court.  In December 2015 Sutcliffe was assessed as being "no longer mentally ill". In August 2016, a medical tribunal ruled that he no longer required clinical treatment for his mental condition, and could be returned to prison. Sutcliffe is reported to have been transferred from Broadmoor to Frankland Prison in Durham in August 2016.
