Denis Papin
Denis Papin FRS (; 22 August 1647 – 26 August 1713) was a French physicist, mathematician and inventor, best known for his pioneering invention of the steam digester, the forerunner of the pressure cooker, the steam engine, the centrifugal pump, submersible and possibly the paddlesteamer (1707). Early life and education Born in Chitenay (Loir-et-Cher, Centre-Val de Loire Région), Papin attended a Jesuit school there. In 1661, he attended the University of Angers, from which he graduated with a medical degree in 1669. Career In 1673, Papin worked with Christiaan Huygens and Gottfried Leibniz in Paris, and became interested in using a vacuum to generate motive power. In 1675, he first visited London, where he worked with Robert Boyle from 1676 to 1679, publishing an account of his work in ''Continuation of New Experiments'' (1680). During this period, Papin invented the '' steam digester,'' a type of pressure cooker with a safety valve. He first addressed the Roya ...

Siebe Gorman
Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe, a Germany, German-born British engineer chiefly known for his contributions to diving equipment. Siebe plc started in the 1970s as a continuation of Siebe Gorman when Siebe Gorman started to take over other firms, to mean the new conglomerate to distinguish it from Siebe Gorman's original breathing apparatus and diving gear core business. Siebe plc was once one of the United Kingdom's largest engineering businesses. It was a constituent of the FTSE 100 Index but in 1999 it merged with BTR plc to form Invensys. Invensys was taken over by the French multinational Schneider Electric for £3.4 billion in January 2014.

Diving Bell
A diving bell is a rigid chamber used to transport divers from the surface to depth and back in open water, usually for the purpose of performing underwater work. The most common types are the open-bottomed wet bell and the closed bell, which can maintain an internal pressure greater than the external ambient. Diving bells are usually suspended by a cable, and lifted and lowered by a winch from a surface support platform. Unlike a submersible, the diving bell is not designed to move under the control of its occupants, or to operate independently of its launch and recovery system. The wet bell is a structure with an airtight chamber which is open to the water at the bottom, that is lowered underwater to operate as a base or a means of transport for a small number of divers. Air is trapped inside the bell by Hydrostatic pressure, pressure of the water at the interface. These were the first type of diving chamber, and are still in use in modified form. The closed bell is a pressur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edict Of Nantes
The Edict of Nantes () was an edict signed in April 1598 by Henry IV of France, King Henry IV and granted the minority Calvinism, Calvinist Protestants of France, also known as Huguenots, substantial rights in the nation, which was predominantly Catholic Church, Catholic. While upholding Catholicism as the State_religion, established religion, and requiring the re-establishment of Catholic worship in places it had lapsed, it granted certain religious toleration to the Protestant Huguenots, who had been waging a long and bloody struggle for their rights in France. The Edict of Nantes helped to end the Wars of Religion in France, which had been raging for decades. It also ensured that the Protestant minority in France would have a measure of religious and political freedom, and helped to establish France as a more tolerant and pluralistic society. However, the Edict was eventually revoked by King Louis XIV in 1685, leading to a mass exodus of Huguenots from France and a loss of t ...

Louis XIV Of France
LouisXIV (Louis-Dieudonné; 5 September 16381 September 1715), also known as Louis the Great () or the Sun King (), was King of France from 1643 until his death in 1715. His verified reign of 72 years and 110 days is the List of longest-reigning monarchs, longest of any monarch in history. An emblem of the Absolutism (European history), age of absolutism in Europe, Louis XIV's legacy includes French colonial empire, French colonial expansion, the conclusion of the Thirty Years' War involving the Habsburgs, and a controlling influence on the Académie royale de peinture et de sculpture, style of fine arts and architecture in France, including the transformation of the Palace of Versailles into a center of royal power and politics. Louis XIV's pageantry and opulence helped define the French Baroque architecture, French Baroque style of art and architecture and promoted his image as absolute ruler of France in the early modern period. Louis XIV began his personal rule of France ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huguenot
The Huguenots ( , ; ) are a Religious denomination, religious group of French people, French Protestants who held to the Reformed (Calvinist) tradition of Protestantism. The term, which may be derived from the name of a Swiss political leader, the Genevan burgomaster Besançon Hugues, was in common use by the mid-16th century. ''Huguenot'' was frequently used in reference to those of the Reformed Church of France from the time of the Protestant Reformation. By contrast, the Protestant populations of eastern France, in Alsace, Moselle (department), Moselle, and Montbéliard, were mainly Lutheranism, Lutherans. In his ''Encyclopedia of Protestantism'', Hans Hillerbrand wrote that on the eve of the St. Bartholomew's Day massacre in 1572, the Huguenot community made up as much as 10% of the French population. By 1600, it had declined to 7–8%, and was reduced further late in the century after the return of persecution under Louis XIV, who instituted the ''dragonnades'' to forcibly ...

Safety Valve
A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would be a rupture disk. Safety valves were first developed for use on steam boilers during the Industrial Revolution. Early boilers operating without them were prone to explosion unless carefully operated. Vacuum safety valves (or combined pressure/vacuum safety valves) are used to prevent a tank from collapsing while it is being emptied, or when cold rinse water is used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures. When sizing a vacuum safety valve, the calculation method is not defined in any norm, particularly in the hot CIP / cold water scenario, but some ma ...

Pressure Cooker
A pressure cooker is a sealed vessel for cooking food with the use of high pressure steam and water or a water-based liquid, a process called pressure cooking. The high pressure limits boiling and creates higher temperatures not possible at lower pressures, allowing food to be cooked faster than at normal pressure. The prototype of the modern pressure cooker was the steam digester invented in the seventeenth century by the physicist Denis Papin. It works by expelling air from the vessel and trapping steam produced from the boiling liquid. This is used to raise the internal pressure up to one atmosphere above ambient and gives higher cooking temperatures between . Together with high thermal heat transfer from steam it permits cooking in between a half and a quarter the time of conventional boiling as well as saving considerable energy. Almost any food that can be cooked in steam or water-based liquids can be cooked in a pressure cooker. Modern pressure cookers have many safety f ...

Robert Boyle
Robert Boyle (; 25 January 1627 – 31 December 1691) was an Anglo-Irish natural philosopher, chemist, physicist, Alchemy, alchemist and inventor. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. He is best known for Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, ''The Sceptical Chymist'' is seen as a cornerstone book in the field of chemistry. He was a devout and pious Anglican and is noted for his works in theology. Biography Early years Boyle was born at Lismore Castle in County Waterford, in the far south of Ireland, the seventh son and fourteenth child of Richard Boyle, 1st Earl of Cork, the 1st Earl of Cork ("the Great Earl of Cork") and Catherine Fenton Boyle, Catherine Fenton.
