A method of producing decabromodiphenyl alkanes includes the steps of charging a reaction vessel with bromine and a bromination catalyst and introducing a diphenyl alkane into the vessel at a location above the level of the charge bromine and catalyst. Two or more distributing belts are coupled to the distributing pulley and two or more collecting belts are coupled to the collecting pulley from mutually opposite radial directions. The heating resistors are supplied with energy, and a difference is set between a manner of supplying energy to one heating resistor and a manner of supplying energy to the other heating resistor. An alternate embodiment provides a connector system and method of stamping and shaping a tool head integrally formed with a receiver.
