Timeline Of United States Inventions (before 1890)
The United States provided many inventions in the time from the Colonial Period to the Gilded Age, which were achieved by inventors who were either native-born or naturalized citizens of the United States. Copyright protection secures a person's right to his or her first-to-invent claim of the ''original'' invention in question, highlighted in Article I, Section 8, Clause 8 of the United States Constitution, which gives the following enumerated power to the United States Congress: In 1641, the first patent in North America was issued to Samuel Winslow by the General Court of Massachusetts for a new method of making salt. On April 10, 1790, President George Washington signed the Patent Act of 1790 (1 Stat. 109) into law proclaiming that patents were to be authorized for "any useful art, manufacture, engine, machine, or device, or any improvement therein not before known or used". On July 31, 1790, Samuel Hopkins of Pittsford, Vermont became the first person in the Unit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent Act Of 1836
The Patent Act of 1836 () established a number of important changes in the United States patent system. These include: * The examination of patent applications prior to issuing a patent. This was the second time this was done anywhere in the world. The previous occasion was in the United States from 1790 to 1793 under the Patent Act of 1790. Previously, patents were issued on all applications, even if they were direct copies of earlier patents.Waltersheid, Edward C. (1998) ''To Promote the Progress of Useful Arts, American Patent Law and Administration'' Littleton: Rothman pp 3. It was left to the courts to decide validity in the event of a lawsuit. * The option of extending an existing patent's term for an additional seven years, making the maximum term of patent 21 years. (This was abolished in 1861 and replaced with a single 17-year term.) *The hiring of professional patent examiners. Initially only one examiner was hired, but soon a second one was hired to handle the increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reflecting Instrument
Reflecting instruments are those that use mirrors to enhance their ability to make measurements. In particular, the use of mirrors permits one to observe two objects simultaneously while measuring the angular distance between the objects. While reflecting instruments are used in many professions, they are primarily associated with celestial navigation as the need to solve navigation problems, in particular the problem of the longitude, was the primary motivation in their development. Objectives of the instruments The purpose of reflecting instruments is to allow an observer to measure the altitude of a celestial object or the angular distance between two objects. The driving force behind the developments discussed here was the solution to the problem of finding one's longitude at sea. The solution to this problem was seen to require an accurate means of measuring angles and the accuracy was seen to rely on the observer's ability to measure this angle by simultaneously observing ...

Quadrant (instrument)
A quadrant is an instrument used to measure angles up to 90°. Different versions of this instrument could be used to calculate various readings, such as longitude, latitude, and time of day. It was first proposed by Ptolemy as a better kind of astrolabe. Several different variations of the instrument were later produced by medieval Muslim astronomers. Mural quadrants were important astronomical instruments in 18th-century European observatories, establishing a use for positional astronomy. Etymology The term ''quadrant'', meaning one fourth, refers to the fact that early versions of the instrument were derived from astrolabes. The quadrant condensed the workings of the astrolabe into an area one fourth the size of the astrolabe face; it was essentially a quarter of an astrolabe. History During Rigvedic times in ancient India, quadrants called 'Tureeyam's were used to measure the extent of a great solar eclipse. The use of a Tureeyam for observing a solar eclipse by Ri ...

Octant (instrument)
The octant, also called a reflecting quadrant (instrument), quadrant, is a reflecting instrument used in navigation. Etymology The name ''octant'' derives from the Latin ''octans'' meaning ''eighth part of a circle'', because the instrument's arc is Circular sector, one eighth of a circle. ''Reflecting quadrant'' derives from the instrument using mirrors to reflect the path of light to the observer and, in doing so, doubles the angle measured. This allows the instrument to use a one-eighth of a Turn (geometry), turn to measure a quarter-Turn (geometry), turn or Circular sector, quadrant. Origin of the octant Newton's reflecting quadrant Isaac Newton's reflecting quadrant was invented around 1699. A detailed description of the instrument was given to Edmond Halley, but the description was not published until after Halley's death in 1742. It is not known why Halley did not publish the information during his life, as this prevented Newton from getting the credit for the inven ...

International Swimming Hall Of Fame
The International Swimming Hall of Fame and Museum (ISHOF) is a history museum and hall of fame, located at One Hall of Fame Drive, Fort Lauderdale, Florida, United States, operated by private interests and serving as the central point for the study of the history of swimming in the United States and world. ISHOF exhibits include ancient art and both reproductions and original art depicting famous moments in swimming history from ancient times to modern, swimwear, civil rights, memorabilia, and artifacts belonging to persons who have promoted or excelled in aquatics. It is recognized by FINA (''Fédération Internationale de Natation'') as the official hall for the aquatics sports. History 20th century In 1965, Johnny Weissmuller became the president of the International Swimming Hall of Fame, that with this charge in 1970 was present at the Commonwealth Games in Jamaica and was introduced to Queen Elizabeth. ISHOF was incorporated in Florida as a non-profit educational corpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swim Fins
Swimfins, swim fins, diving fins, or flippers are finlike accessories worn on the feet, legs or hands and made from rubber, plastic, carbon fiber or combinations of these materials, to aid movement through the water in water sports activities such as swimming, bodyboarding, bodysurfing, float-tube fishing, kneeboarding, riverboarding, scuba diving, snorkeling, spearfishing, underwater hockey, underwater rugby and various other types of underwater diving. Swimfins help the wearer to move through water more efficiently, as human feet are too small and inappropriately shaped to provide much thrust, especially when the wearer is carrying equipment that increases hydrodynamic drag. Very long fins and monofins used by freedivers as a means of underwater propulsion do not require high-frequency leg movement. This improves efficiency and helps to minimize oxygen consumption. Short, stiff-bladed fins are effective for short bursts of acceleration and maneuvering, and are useful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
