Abstract: A used needle is inserted in a housing of a needle apparatus disabling device. As the needle is pushed downwards sealing a collar opening and bears against a stationary cutter blade. The needle is pushed further into the device where it contacts upper and lower electrodes. An electric current passes through the needle, which causes it to become heated resistively to destruction. A voltage drop between the electrodes is detected by a processor activating a motor driven movable cutter blade which then severs a remaining stub or remnant of the needle portion and simultaneously urges the severed stub downwardly onto the electrodes to ensure its complete destruction. During this process any sparks or airborne contaminants, or combustion gases are prevented from escaping through the opening by the sealing action of the apparatus.

Abstract: The invention is a method to regulate gas pressure by controlling the expansion of a gas through an air motor that is attached to an electric generator. There are four components. The first is a sensor that measures the pressure of the gas coming into the air motor. The second is an air motor that changes the pressure of the gas into mechanical energy. The third is a generator that takes the mechanical energy from the air motor and changes it into the electrical energy. The forth is a control unite. The control unit reads the pressure of the gas from the sensor and varies the electric load on the generator. The varying of the electrical load on the generator varies the torque on the air motor which changes the pressure of the gas passing through the air motor.
