Composite material reinforcement materials. Another important factor is the gross quantity of material to be produced. Large quantities can be used to justify high capital expenditures for rapid and automated manufacturing technology. Small production quantities are accommodated with lower capital expenditures but higher labour and tooling costs at a correspondingly slower rate. Many commercially produced composites use a polymer matrix material often called a resin solution. There are many different polymers available depending upon the starting raw ingredients. There are several broad categories, each with numerous variations. The most common are known as polyester, vinyl ester, epoxy, phenolic, polyimide, polyamide, polypropylene, PEEK,
Berliner Gramophone Berliner Gramophone Berliner Gramophone – its discs identified with an etched-in "E. Berliner's Gramophone" as the logo – was the first (and for nearly ten years the only) disc record label in the world. Its records were played on Emile Berliner's invention, the Gramophone, which competed with the wax cylinder–playing phonographs that were more common in the 1890s. Emile Berliner received U.S. patents 372,786 and 382,790 on the Gramophone on November 8, 1887, and May 15, 1888, respectively. This was before the organization of the North American Phonograph Company, which first produced cylinder recordings for public use, and thus Berliner's
