) The development condensite was valuable contribution the Edison phonograph business and major chemical innovation. When Edison thought about . found that phenol resins could mixed with binding agents and moulded into hard heat-resistant shapes. (Condensite refers the condensation phenol and formaldehyde which produces the resin. There can be little doubt that the Edison company copied the Victrola; in 1911 Edison was designing cabinets for the new machine "like the Victrola, but far finer. The West Orange laboratory was charged with the initial design three disc machines— one them direct competitor the Victrola. The excellence the Edison disc records g was directly attributable Aylsworth's condensite surface." working around the important patents Eldridge Johnson, the lab worked closely with the legal department TAE Inc. Much the R&D work the disc was done circumvent the patents the swinging arm (that carried the reproducer), and enclosed horn design. The lab had come with design that could compete with the Victrola while not infringing on its strong patent position. Aylsworth improved the phenol resins first developed by Baekeland and produced material called condensite which was a purer resin with less by-products. The specifications and drawings of the disc machines were the contribution the new Engineering Department.IX- 8 from the laboratory, Leo Baekerland was experimenting with the same resins his efforts find substitute for shellac
