By the second century BC, the Chinese employed thin strips of mulberry bark as crude packaging material. Cardboard box packaging was used as far back as 1817, but it wasn't until the turn of the century that corrugated boxes came online. As the result of an accident, Robert Gair invented prefabricated paperboard in Brooklyn New York. While printing an order of seed bags, the metal ruler that was used to crease the bags slipped and cut them. Thus by cutting and creasing in one operation, Gair discovered he could create prefabricated paperboard boxes. The popularity of flaked cereals and “the best to you each morning,” skyrocketed the use of cardboard boxes as cereal cartons.
KMC Systems Inc, a designer of precision automated medical instruments, was having trouble with a pulley-to-shaft connection within an automated analyzer. Positional accuracy is extremely important in this application, but loosening set screws and other connection methjods proved unreliable, and constant rework and repairs were difficult and costly.
After deciding that a better connection system was needed, the designers discovered the Concentric Maxi Torque system. By integrating the Concentric Maxi Torque connection system, they were able to improve concentricity, which in turn, improved positional accuracy. The Concentric Maxi Torque system also eliminated the need for flats on the mating shaft, providing a more cost effective and reliable solution.
