| 20100282715 | METHOD AND APPARATUS FOR CONVERTING A MIG WELDER INTO A CARBON-ARC CUTTER - Apparatus and methods convert a MIG welder into an effective cutting machine. A hand-held unit and a feeder supply a wire through the hand-held unit, the wire including a carbon-containing core. A source of electrical energy is connected to the wire being fed and the metal to be cut such that an arc is created with sufficient energy to melt the metal in a localized region, and further apparatus is included for directing a gas to blow away the molten metal. The gas may be air or oxygen. A feedstock for metal cutting operations according to the invention contains a roll of wire having a mild steel jacket and a carbon-containing core. The carbon in the core of the wire may be provided in the form of natural or synthetic graphite powder, and may further include an additive to accelerate delivery force or enhance molten metal flow. | 11-11-2010 |

The ridge portion is operable to mate with a workpiece to form a trench on the workpiece. A plurality of electrodes extend from the ridge portion and are oriented to form a plurality of cooling holes within the trench on the workpiece. | 08-04-2011 |
| 20110247998 | Welding or cutting device - A welding or cutting device for welding or cutting electrically conductive work pieces has a pipe that accommodates feed lines, a nozzle for exit of a welding or cutting jet, such as a flame, for example, disposed at an end of the pipe, forming a device tip with its free end, and an inductive sensor device for measuring the distance between the device tip and the work piece. The sensor device has at least one magnetic coil, the windings of which run about a longitudinal device axis. The sensor device is a separate module, which is pushed onto the pipe and/or the nozzle, and releasably connected with the pipe and/or the nozzle. | 10-13-2011 |
| 20110253678 | METHOD FOR FABRICATION OF A QUADRUPOLE MASS FILTER OR QUADRUPOLE ION TRAP - The present invention relates to a method for fabricating a quadrupole mass filter (QMF) or a quadrupole ion trap (QIT). | 10-20-2011 |
| 20120145676 | Metal Ablation in Supersonic Expansion Gas Coupled to an Ion Mass Filter - A novel combined rectilinear ion trap mass spectrometer (RIT-MS)-coupled to expansion nozzle instrument and its application to preparative materials to create novel materials and material surfaces is described herein. | 06-14-2012 |
| 20120187091 | METHOD AND APPARATUS FOR TRIMMING A SAMPLE FROM A COILED METAL WEB - Sample extraction or trimming from an end strip of an elongated formed metal that is coiled in layers within a tensioned metal coil resting on driven rollers. A cut channel is formed across the material width. In some embodiments the cut channel is formed between the rollers and by cutting at an angle relative to the coil outer surface. Coil weight and/or a coil tensioner mechanism inhibits coil relaxation along the cut channel by maintaining tension on wrapped layers against each other when the coil is unbanded for sample extraction. The coil is rotated so that the cut channel clears the rollers laterally. Material downstream the cut is then separated from the coil. After trimming and/or sample extraction the coil maintains rolled tautness for ease of rebanding. | 07-26-2012 |

| 20130126482 | POWER SUPPLY DEVICE AND ARC MACHINING POWER SUPPLY DEVICE - A power supply device that is applicable to both 200 V and 400 V series input power by switching the operation of an auxiliary switching circuit with a switching switch. When a relatively large output is requested, PWM control is performed to adjust the on pulse width of a control pulse signal provided to switching elements of an inverter circuit and an auxiliary switching circuit, which is operated in cooperation with the inverter circuit. When a relatively small output is requested, PSM control is performed to adjusting a phase difference of two control pulse signals provided to the same set of switching elements in the inverter circuit. | 05-23-2013 |
| 20130264313 | FIBER END SURFACE MACHINING DEVICE AND FIBER POSITION STRUCTURE THEREOF - A fiber end surface machining device includes a base seat, a pair of electrodes, and a fiber position structure. The fiber position structure includes a resisting unit and a driving member. The resisting unit is movably assembled on the base seat and is located between the pair of electrodes. The driving member is rotatably assembled on the base seat adjacent to the resisting unit. The driving member includes a cam portion resisting the resisting unit. When the cam portion rotates to drive the resisting unit to move towards an optical fiber connector, the resisting unit drives an optical fiber of the optical fiber connector to move relative to an optical fiber ferrule of the optical fiber connector, and a length of the optical fiber protruding out of the optical fiber ferrule is adjusted. | 10-10-2013 |
