Invention Promotion Firms"Some invention promotion firms may claim to know or have special access to manufacturers who are likely to be interested in licensing your invention. In addition, some firms may claim to represent manufacturers on the look-out for new product ideas.

From 3D Printing

Any tridimensional object can be sliced into several thin slices such that when they are put together again they make the original body. This is exactly what the 3D-printing technology does.

From Money

The $1 legal tender note was issued by the United States during the Civil War. Pyramids, eagles, goddesses, and frogs —even Santa Claus. These are just a few of the images that have appeared on American currency over the past three centuries. The pyramid is composed of 13 rows of building blocks, on the first of which are the Roman numerals representing 1776. The Latin inscription Novus Ordo Seclorum translates to 'A New Order of the Ages.' Some of these symbols are no longer used, but many of them can still be found on present-day U.S. notes and coins.
