Abstract: An aerial navigation system comprises four anchor points mounted on top of four upright members respectively at substantially same height from a ground, a carrier device coupled to a first set of four electric motors mounted at the four anchor points through a set of first wires. The set of first wires, the four upright members and the ground effectively define a volume. The carrier device is moveable in a bounded horizontal plane defined by the four anchor points. A robotic device is suspended from the carrier device using a second wire and moves vertically relative to the carrier device through activation of a fifth electric motor. A control unit is coupled to the first set of four electric motors and the fifth electric motor for controlling the three-dimensional movement of the robotic device to permit navigation from a current location to a target location inside the defined volume.

Abstract: A microwave distillation apparatus provides destructive distillation of whole waste tires. The apparatus includes a housing including a plurality of vertically arranged chambers. A preheat chamber provides preheating of a whole waste tire received therein. 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.

Abstract: A lighting control system for discharge lamps which comprises a ballast for supplying energy from a power source to a lamp. First and second capacitors and a first control relay and contact set control the supply of energy from the ballast to the lamp to switch the lamp between dimmed and normal wattage operational modes. A second control relay and contact set connects a single output control wire to neutral when a predetermined condition is sensed or a switch is thrown. The first control relay, which is connected at one end to the lamp ballast, is energized when the other end thereof is connected to neutral via the second control relay. The first control relay in turn closes the normally open contact set, which is connected to one of the capacitors, to increase the energy provided to the lamp. In accordance with one embodiment the first capacitor and the contact set of the first control relay are connected in series, and together are connected parallel to the second capacitor.
