Timeline of United States inventions 1. A timeline of United States inventions 1. United States within a historical context, dating from the era of the Cold War, which have been achieved by inventors who are either native born or naturalized citizens of the United States. Copyright protection secures a persons right to his or her first to inventclaim 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 To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries. In 1. North America was issued to Samuel Winslow by the General Court of Massachusetts for a new method of making salt. On April 1. President George Washington signed the Patent Act of 1. Stat. 1. 09 into law which proclaimed 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 3. 5 January Mae Jemison, the first female AfricanAmerican astronaut, is selected to head the DARPA and NASAsponsored 100Year Starship project, which aims to conduct. This update will see the death of the old email program Outlook Express, as well as the depreciation of the popular Paint application. As Microsoft told Gizmodo back.

I have the all black, with the tritium front sight forget the model SD40, and most of the Sigma parts interchange just fine. Samuel Hopkins of Pittsford, Vermont became the first person in the United States to file and to be granted a patent for an improved method of Making Pot and Pearl Ashes. The Patent Act of 1. Ch. 3. 57, 5 Stat. United States patent law to the extent of establishing a patent office where patent applications are filed, processed, and granted, contingent upon the language and scope of the claimants invention, for a patent term of 1. However, the Uruguay Round Agreements Act of 1. URAA changed the patent term in the United States to a total of 2. June 8, 1. 99. 5, thus bringing United States patent law further into conformity with international patent law. The modern day provisions of the law applied to inventions are laid out in Title 3.

Space observatory. The Hubble Space Telescope. A space observatory is any instrument, such as a telescope, in outer space which is used for observation of distant planets, galaxies, and other outer space objects. In 1. 94. 6, American theoretical astrophysicist Lyman Spitzer was the first to conceive the idea of a telescope in outer space, a decade before the Soviet Union launched the first artificial satellite, Sputnik into orbit.

Space Shuttle Discovery STS 3. Blowout preventer annularAn annular blowout preventer is a large valve that uses a wedge to seal off a wellhead. It has a donut like rubber seal, known as an elastomeric packing unit, reinforced with steel ribs. During drilling or well interventions, the valve may be closed if overpressure from an underground zone causes formation fluids such as oil or natural gas to enter the wellbore and threaten the rig. The annular blowout preventer was invented by Granville Sloan Knox in 1. September 9, 1. 95. Tupperware. Tupperware is airtight plastic containers used for the preparation, storage, containment, and serving of perishable food in the kitchen and home. Tupperware was invented in 1. American chemist Earl Silas Tupper who devised a method of purifying black polyethylene slag, a waste product produced in oil refinement, into a molded substance that was flexible, tough, non porous, non greasy and translucent. Available in many colors, the plastic containers with burp seal did not become a commercial success until Brownie Wise, a Florida housewife, began throwing Tupperware parties in 1. Spoonplug. A spoonplug is a form of fishing lure. The spoonplug was invented by Elwood L. Buck Perry, then a physics and math teacher in Hickory, North Carolina. Elwood Perry combined science with a logical approach to fishing to create a total fishing system. He is credited as being the father of structure fishing and was later inducted into the National Freshwater Fishing Hall of Fame. Chipper teeth. An example of chipper teeth. A chipper teeth is a variant of a saw chain used on a chainsaw. Using a tooth that is curled over the top of the chain, there are alternate teeth which point left and right. In 1. 94. 6, American logger Joseph Buford Cox of Portland, Oregon invented chipper teeth, which is still widely used today and represents one of the biggest influences in the history of timber harvesting. Filament tape. Filament tape or strapping tape is a pressure sensitive tape used for several packaging functions such as closing corrugated fiberboard boxes, reinforcing packages, bundling items, pallet utilizing, etc. It consists of a pressure sensitive adhesive coated onto a backing material which is usually a polypropylene or polyester film and fiberglass filaments embedded to add high tensile strength. Filament tape was invented in 1. Cyrus Woodrow Bemmels. In 1. 94. 9, it was placed on the market and was an immediate success. Credit card. A credit card is part of a system of payments named after the small plastic card issued to users of the system. The issuer of the card grants a line of credit to the consumer from which the user can borrow money for payment to a merchant or as a cash advance to the user. In 1. 94. 6, American banker John C. Biggins of the Flatbush National Bank of Brooklyn invented the first bank issued credit card. Diaper waterproofA diaper or nappy is an absorbent garment for incontinent people. The dampless or waterproof diaper was invented in 1. Marion Donovan used a shower curtain from her bathroom to create the Boater, the first re usable and leak proof diaper that contained plastic lined cloth. Donovans other innovation was replacing safety pins with plastic snaps on the sides of diapers. First sold in 1. 94. Saks Fifth Avenues flagship store in New York City, patents were later issued in 1. Donovan who later sold the rights to the waterproof diaper for 1 million. Transistor. A replica of the first working transistor. In electronics, a transistor is a semiconductor device commonly used to amplify or switch electronic signals. Because the controlled output power can be much larger than the controlling input power, the transistor provides amplification of a signal. The transistor is the fundamental building block of all modern electronic devices, and is used in radio, telephone, computer, and other electronic systems. From November 1. 7, 1. December 2. 3, 1. John Bardeen and Walter Brattain at AT T Bell Labs, underwent experimentations and finally observed that when two gold point contacts were applied to a crystal of germanium, a signal was produced whereby the output power was larger than the input. The manager of the Bell Labs semiconductor research group, William Shockley, saw the potential in this and worked over the next few months greatly expanding the knowledge of semiconductors in order to construct the first point contact transistor.
