Problem: Background: 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.
Context: 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.
Question: What did Watt and Boulton end up doing about this?
Answer: Watt adamantly opposed this and they circumvented the patent by their sun and planet gear in 1781.

Background: Hippolytus of Rome (170 - 235 AD) was one of the most important 3rd-century theologians in the Christian Church in Rome, where he was probably born. Photios I of Constantinople describes him in his Bibliotheca (cod. 121) as a disciple of Irenaeus, who was said to be a disciple of Polycarp, and from the context of this passage it is supposed that he suggested that Hippolytus so styled himself. However, this assertion is doubtful.
Context: As a presbyter of the church at Rome under Pope Zephyrinus (199 - 217 AD), Hippolytus was distinguished for his learning and eloquence. It was at this time that Origen of Alexandria, then a young man, heard him preach. He accused Pope Zephyrinus of modalism, the heresy which held that the names Father and Son are simply different names for the same subject. Hippolytus championed the Logos doctrine of the Greek apologists, most notably Justin Martyr, which distinguished the Father from the Logos ("Word"). An ethical conservative, he was scandalized when Pope Callixtus I (217 - 222 AD) extended absolution to Christians who had committed grave sins, such as adultery. Hippolytus himself advocated an excessive rigorism. At this time, he seems to have allowed himself to be elected as a rival Bishop of Rome, and continued to attack Pope Urban I (222 - 230 AD) and Pope Pontian ( 230 - 235 AD). G. Salmon suggests that Hippolytus was the leader of the Greek-speaking Christians of Rome. Allen Brent sees the development of Roman house-churches into something akin to Greek philosophical schools gathered around a compelling teacher. Under the persecution at the time of Emperor Maximinus Thrax, Hippolytus and Pontian were exiled together in 235 AD to Sardinia, likely dying in the mines. It is quite probable that, before his death there, he was reconciled to the other party at Rome, for, under Pope Fabian (236-250), his body and that of Pontian were brought to Rome. The so-called chronography of the year 354 (more precisely, the Catalogus Liberianus, or Liberian Catalogue) reports that on August 13, probably in 236 AD, the two bodies were interred in Rome, that of Hippolytus in a cemetery on the Via Tiburtina, his funeral being conducted by Justin the Confessor. This document indicates that, by about 255 AD, Hippolytus was considered a martyr and gives him the rank of a priest, not of a bishop, an indication that before his death the schismatic was received again into the Church.
