Abstract: A striking apparatus for all fighting art forms such as boxing to improve a user's fighting skills. The striking apparatus includes a timing ball having a link disposed thereon; an elongated adjustable rope; a swivel mounted to a swivel plate, the swivel plate being mounted to a backboard; the backboard being optionally attached to a frame; the link disposed on the timing ball being attached to the elongated adjustable rope, the rope being attached to the swivel; and the timing ball configured to be struck by the knuckles of a user's fist. Another embodiment of the invention includes a punching apparatus station for all fighting art forms which generally includes the same configuration as the striking apparatus referenced-above. Importantly, the striking apparatus advantageously is a cross between a speed bag, a double end bag, and a maze ball but is beneficially more effective than all three.

Abstract: A mixture comprised of about 60-85% of 2,4-toluenediamine (2,4-TDA) and about 15-40% of 2,6-toluenediamine (2,6-TDA) is melted, the temperature of the mixture is lowered to a 2,4-TDA nucleation temperature, and the temperature of the mixture is gradually reduced from the nucleation temperature to about 65 to about 70° C. The resultant mixture is in the form of a solids phase enriched in 2,4-TDA, and a novel and useful liquid phase enriched in 2,6-TDA. These phases are separated. Preferably the solids are further purified by “sweating” them and removing the sweated liquid impurities. The sweated liquid can be recycled together with another charge of a mixture comprised of 2,4-TDA and 2,6-TDA. 2,4-TDA can be produced with a purity of 96-99%.
