An irradiation chamber, located below the preheat chamber and thermally coupled to the preheat chamber such that heat generated in the irradiation chamber creates heat convection currents in the preheat chamber, receives a preheated whole waste tire from the preheat chamber. A microwave energy supply supplies microwave energy to the irradiation chamber to provide destructive distillation of a tire received in that chamber. A cooling chamber, located below the irradiation chamber, receives by-products of the destructive distillation therefrom and provides delivery of the by-products from the housing.

Abstract: A torque limiting nut comprising a nut cap and a nut base with axially aligned bores to receive a fastener such as a bolt. The base and the cap are constructed so that the two engage one another in such manner that opposed and serrated surfaces on one or both of the base and the cap cause the two to rotate together about a threaded bolt or stud until a predetermined torquing force is reached. Thereafter, one of the cap or base will slip relative to the other allowing for rotation of one relative to the other. In this way, a required torque level can be applied to the nut to cause a rotation thereof on a threaded shank of a bolt or other fastener until that predetermined torque force has been reached.
