Timeline Of United States Inventions (1890–1945)
A timeline of United States inventions (1890–1945) encompasses the ingenuity and innovative advancements of the United States within a historical context, dating from the Progressive Era to the end of World War II, which have been achieved by inventors who are 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 which proclaimed that patents were to be authorized for "any useful art, manufacture, engine, machine, or device, or any improvement there ...

Progressive Era
The Progressive Era (late 1890s – late 1910s) was a period of widespread social activism and political reform across the United States focused on defeating corruption, monopoly, waste and inefficiency. The main themes ended during American involvement in World War I (1917–1918) while the waste and efficiency elements continued into the 1920s. Progressives sought to address the problems caused by rapid industrialization, urbanization, immigration, and political corruption; and by the enormous concentration of industrial ownership in monopolies. They were alarmed by the spread of slums, poverty, and what they perceived as the "exploitation" of labor. Multiple overlapping progressive movements fought perceived social, political and economic ills by advancing democracy, scientific methods, professionalism and efficiency; regulating businesses, protecting the natural environment, and improving working conditions in factories and living conditions of the urban poor.

Term Of Patent In The United States
In the United States, under current patent law, the term of patent, provided that maintenance fees are paid on time, is 20 years from the filing date of the earliest U.S. or international ( PCT) application to which priority is claimed (excluding provisional applications). The patent term in the United States was changed in 1995 to bring U.S. patent law into conformity with the World Trade Organization's Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs) as negotiated in the Uruguay Round. As a side effect, it is no longer possible to maintain submarine patents in the U.S., since the patent term now depends on the priority date, not the issue date. Design patents have a shorter term than utility patents. Design patents filed on or after May 13, 2015 have a term of 15 years from issuance. Design patents filed prior to May 13, 2015 have a term of 14 years from issuance. History The original patent term under the 1790 Patent Act was decided individually for ...

Herman Hollerith
Herman Hollerith (February 29, 1860 – November 17, 1929) was a German-American statistician, inventor, and businessman who developed an electromechanical tabulating machine The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. Later models w ... for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in 1884, marks the beginning of the era of mechanized binary code and semiautomatic data processing systems, and his concept dominated that landscape for nearly a century. Hollerith founded a company that was amalgamated in 1911 with several other companies to form the Computing-Tabulating-Recording Company. In 1924, the company was renamed "International Business Machines" (IBM) and became one of the largest and mos ...

Tabulating Machine
The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. Later models were widely used for business applications such as accounting and inventory control. It spawned a class of machines, known as unit record equipment, and the data processing industry. The term "Super Computing" was used by the ''New York World'' newspaper in 1931 to refer to a large custom-built tabulator that IBM made for Columbia University. 1890 census The 1880 census had taken eight years to process. Since the U.S. Constitution mandates a census every ten years to apportion both congressional representatives and direct taxes among the states, a combination of larger staff and faster-recording systems was required. In the late 1880s Herman Hollerith, inspired by conductors using holes punched in different positions on a railway ...

William Phelps Eno
William Phelps Eno (June 3, 1858 – December 3, 1945) was an American businessman responsible for many of the earliest innovations in road safety and traffic control. He is sometimes known as the "Father of traffic safety", despite never having learned to drive a car himself. Among the innovations credited to Eno are traffic regulations, the stop sign, the pedestrian crosswalk, the traffic circle, the one-way street, the taxi stand, and pedestrian safety islands. His rotary traffic plan was put into effect at Columbus Circle, New York City, in 1905, at the Arc de Triomphe in Paris, 1907, Piccadilly Circus in 1926, and the Rond Point on the Champs-Élysées in 1927.

Stop Sign
A stop sign is a traffic sign designed to notify drivers that they must come to a complete stop and make sure the intersection is safely clear of vehicles and pedestrians before continuing past the sign. In many countries, the sign is a red octagon with the word ''STOP'', in either English or the national language of that particular country, displayed in white or yellow. The Vienna Convention on Road Signs and Signals also allows an alternative version: a red circle with a red inverted triangle with either a white or yellow background, and a black or dark blue ''STOP''. Some countries may also use other types, such as Japan's inverted red triangle stop sign. Particular regulations regarding appearance, installation, and compliance with the signs vary by some jurisdiction. Design and configuration The 1968 Vienna Convention on Road Signs and Signals allows for two types of stop sign as well as several acceptable variants. Sign B2a is a red octagon with a white legend.
