Universal Numbering System
The Universal Numbering System, sometimes called the "American System", is a dental notation system commonly used in the United States. Most of the rest of the world uses the FDI World Dental Federation notation, accepted as an international standard by the International Standards Organization as ISO 3950. However, dentists in the United Kingdom commonly still use the older Palmer notation despite the difficulty in representing its graphical components in computerized (non-handwritten) records. Left and right Dental charts are normally arranged from the viewpoint of a dental practitioner facing a patient. The patient's right side appears on the left side of the chart, and the patient's left side appears on the right side of the chart. The labels "right" and "left" on the charts in this article correspond to the patient's right and left, respectively. Universal numbering system Although it is named the "universal numbering system", it is also called the "American system" as ...

American System Of Manufacturing
The American system of manufacturing was a set of manufacturing methods that evolved in the 19th century. The two notable features were the extensive use of interchangeable parts and mechanization for production, which resulted in more efficient use of labor compared to hand methods. The system was also known as armory practice because it was first fully developed in armories, namely, the United States Armories at Springfield in Massachusetts and Harpers Ferry in Virginia (later West Virginia), inside contractors to supply the United States Armed Forces, and various private armories. The name "American system" came not from any aspect of the system that is unique to the American national character, but simply from the fact that for a time in the 19th century it was strongly associated with the American companies who first successfully implemented it, and how their methods contrasted (at that time) with those of British and continental European companies. In the 1850s, the " ...

Open Coach
An open coach is a railway passenger coach that does not have compartments or other divisions within it and in which the seats are arranged in one or more open plan areas with a centre aisle. The first open coaches appeared in the first half of the 19th century in the United States. The prototype for their design were the passenger cabins in the river steamers which were then widespread in America. As a result of their origin they were originally known in Europe as American system passenger coaches or American coaches (''Personenwagen amerikanischen Systems'' or ''Amerikanerwagen'') and the idea soon caught on in European railway companies. Initially they were mainly used for rural regional services, whilst urban local trains and local-distance services were dominated by compartment coaches. Several European railways such as the Royal Württemberg State Railways and the Swiss Northeastern Railway (''Schweizerische Nordostbahn''), however, preferred open coaches from the start for a ...
