20120080409 | OUTPUT CONTROL FOR AUTO-RECONNECT WELDING/CUTTING EQUIPMENT - Apparatus and methods for automatically recalibrating an output current range of a user output current control encoder of an auto-reconnect welding/cutting device. When an input power type connected to an auto-reconnect device is changed, the calibrated range of the user output current control encoder (e.g., output control knob) is automatically transformed in response to the auto-reconnect device sensing at least one characteristic of the input power type. As a result, when a user adjusts the encoder to its maximum full-scale setting, too much current will not be drawn by the auto-reconnect device which would cause a circuit protection component (e.g., a circuit breaker or a fuse) associated with the input power type to trip. Instead, the current that is drawn when the encoder is set to the maximum full-scale setting is no more than about a rated current of the circuit protection component. | 04-05-2012 |

20130334175 | NEEDLE DISABLING DEVICE - 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. | 12-19-2013 |

At the cut-off position, two opposing contact blades pinch the needle, which electrically connects the positive and negative terminals of a battery. Current flows through the contact blades to shear the needle. The sheared portion of the needle then falls into a waste compartment in the bottom of the apparatus. When the syringe is removed from the needle carriage, the needle carriage rotates upwardly and returns to the loading position. | 06-19-2014 |
