Marine Engine
An inboard motor is a marine propulsion system for boats. As opposed to an outboard motor where an engine is mounted outside the hull of the craft, an ''inboard motor'' is an engine enclosed within the hull Hull may refer to: Structures * Chassis, of an armored fighting vehicle * Fuselage, of an aircraft * Hull (botany), the outer covering of seeds * Hull (watercraft), the body or frame of a ship * Submarine hull Mathematics * Affine hull, in affi ... of the boat, usually connected to a propulsion propeller, screw by a driveshaft. In international shipping the marine diesel engines are the largest most powerful engines ever produced. History The first marine craft to utilize inboard motors were steam engines going back to 1805 and the North River Steamboat, ''Clermont'' and the ''Charlotte Dundas''. Harbour tugs, and small steam launches had inboard steam engines. In the 1880s the naphtha engine made its appearance and a few boat engines appeared. Such engines had ...

Beam Engine
A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall. The efficiency of the engines was improved by engineers including James Watt, who added a separate condenser; Jonathan Hornblower and Arthur Woolf, who compounded the cylinders; and William McNaught, who devised a method of compounding an existing engine. Beam engines were first used to pump water out of mines or into canals but could be used to pump water to supplement the flow for a waterwheel powering a mill. The rotative beam engine is a later design of beam engine where the connecting rod drives a flywheel by means of a crank (or, historically, by means of a sun and planet gear). These beam engines could be used to directly power the line-shafting in a mill. They also c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Maudslay
Henry Maudslay ( pronunciation and spelling) (22 August 1771 – 14 February 1831) was an English machine tool innovator, tool and die maker, and inventor. He is considered a founding father of machine tool technology. His inventions were an important foundation for the Industrial Revolution. Maudslay's invention of a metal lathe to cut metal, circa 1800, enabled the manufacture of standard screw thread sizes. Standard screw thread sizes allowed interchangeable parts and the development of mass production. Early life Maudslay was the fifth of seven children of Henry Maudslay, a wheelwright in the Royal Engineers, and Margaret (''nee'' Whitaker), the young widow of Joseph Laundy. His father was wounded in action and so in 1756 became an 'artificer' at the Royal Arsenal, Woolwich (then in Kent), where he remained until 1776 and died in 1780. The family lived in an alley that no longer exists, off Beresford Square, between Powis Street and Beresford Street. Career Maudslay be ...

David Van Nostrand
David Van Nostrand (December 5, 1811 – June 14, 1886) was a New York City publisher. Biography David Van Nostrand was born in New York City on December 5, 1811. He was educated at Union Hall, Jamaica, New York, and in 1826 entered the publishing house of John P. Haven, who gave him an interest in the firm when he became of age. In 1834 he formed a partnership with William Dwight, but the financial crisis of 1837 led to its dissolution. Van Nostrand then accepted an appointment as clerk of accounts and disbursements under Captain John G. Barnard, at that time in charge of the defensive works of Louisiana and Texas, with headquarters at New Orleans. While so engaged he devoted attention to the study of scientific and military affairs, and on his return to New York City he began the importation of military books for officers of the U.S. Army, afterward receiving orders from private individuals and from academic institutions for foreign books of science. His place of business was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Benjamin Prescott
Albert Benjamin Prescott (December 12, 1832, Hastings, New York – February 25, 1905) was an American chemist. He graduated in medicine at the University of Michigan in 1864, and was made assistant professor of organic and applied chemistry, dean of the school of pharmacy, and director of the chemical laboratory over the years. Professor Prescott served as president of the American Chemical Society in 1886, president of the American Association for the Advancement of Science in 1891, and president of the American Pharmacists Association in 1900. During his tenure as Dean at the University of Michigan College of Pharmacy, Prescott encouraged the foundation of what is now the Phi Delta Chi professional pharmacy fraternity. He is buried with his wife and children at Forest Hill Cemetery, adjacent to the University of Michigan Central Campus. Early life Professor Prescott was born on December 12, 1832, in Hasting, New York. He was the youngest of four children in Benjamin Presco ...

Air And Water Pump Indicator Diagram, 1869
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention ( greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Practical Definition Of An Indicator Diagram, 1869
Pragmatism is a philosophical tradition that considers words and thought as tools and instruments for prediction, problem solving, and action, and rejects the idea that the function of thought is to describe, represent, or mirror reality. Pragmatists contend that most philosophical topics—such as the nature of knowledge, language, concepts, meaning, belief, and science—are all best viewed in terms of their practical uses and successes. Pragmatism began in the United States in the 1870s. Its origins are often attributed to the philosophers Charles Sanders Peirce, William James, and John Dewey. In 1878, Peirce described it in his pragmatic maxim: "Consider the practical effects of the objects of your conception. Then, your conception of those effects is the whole of your conception of the object."Peirce, C.S. (1878), "How to Make Our Ideas Clear", ''Popular Science Monthly'', v. 12, 286–302. Reprinted often, including ''Collected Papers'' v. 5, paragraphs 388–410 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
