20100125964MOP WITH RECEPTACLE - Some aspects of the present invention are related to a mop and/or mop head that allows larger debris to pass over at least a portion of the mop head and into a receptacle of the mop head. In some embodiments, the mop head and the receptacle are integrally formed. The mop has debris collecting material coupled to the mop head to collect dust, dirt, and other relatively small debris as the mop moves over a floor. In one particular embodiment, the debris collecting material is a non-woven material. The debris collecting material of the mop can be connected to the mop many different ways. However, in some embodiments, the material is connected via several projections extending from a top surface of the mop head. The projections pass through apertures in the dust collecting material.05-27-2010

20080221349Preparation of Amides of Retinoic Acid Via Mixed Anhydride and Mixed Carbonate Intermediates - Processes for preparing amides of retinoic acid are disclosed. Intermediates useful in the preparation of amides of retinoic acid are also disclosed. In one version of the invention, fenretinide is produced via activation of retinoic acid (tretinoin) via its corresponding mixed anhydride or mixed carbonate followed by reaction of the activated intermediate with 4-aminophenol. Other amides of retinoic acid and isomers of retinoic acid, such as the 9-cis-form or 13-cis-form can also be made by this invention.09-11-2008

20080314885System and Method for Battery-Assisted, Engine-Driven Welding-Type Process - A welding-type system and method for providing supplemental output power in an engine-driven, welding-type system. The welding-type system includes a battery, an engine, and a generator coupled to the engine to be driven to generate a power. The system also includes a power conditioning circuit configured to convert the power generated by the generator to a primary welding-type power and an output configured to deliver the welding-type power to drive a welding-type process during a first state and a second state of the welding-type process. The system further includes a controller configured to monitor the welding-type process and selectively couple the battery to the output during the second state of the welding-type process to provide a supplemental welding-type power to drive the welding-type process during the second state of the welding-type process.12-25-2008
20090145889System and Method for Improved TIG Arc Starting - A system and method for performing a welding-type process includes a welding-type torch having a first electrode connected to receive a welding-type power to effectuate a welding-type process. The welding-type torch also includes a second electrode connected to receive a starting power to initiate the welding-type process and a nozzle surrounding at least a portion of the first electrode.06-11-2009
20100006552Method And Apparatus For Short Arc Welding - A short circuit arc welding system is disclosed. The control scheme uses a current command signal comprised of a long-term current command that sets the long-term current command level and a real-time or short-by-short current command to drive the output current. Feedback is used to determine if the desired arc length is present and to adjust the long-term command. The short-by-short current command is derived from real-time arc current feedback and is used to control the burn-off rate by adjustment of the current command. The short being about to clear is detected in real time. When the process is ending a very low current level is provided to avoid forming a ball. If a short is created, after the low current level, a burst of energy is provided to clear of burn off the short. After the short is cleared, very low current is again provided to avoid forming a large ball, until the wire stops and the process ends.01-14-2010

20080217313Method and Apparatus For Feeding Wire to a Welding Arc - A method and apparatus for feeding wire in a welding system include one or more motors disposed adjacent the wire to drive it. A wire feed motor is also disposed along the wire path, and is closer to the source of wire than the torch, and closer to the source than the one or more motors. The motors may be a pair motors disposed on opposite sides of the wire and move the wire to and away from an arc end of a torch. They preferably reversing the direction of the wire within one process cycle. The or more motors may be a stepper motor, a servo motor, a zero backlash motor, a gearless motor, a planetary drive motor, or a linear actuator (such as a piston), in various embodiments.09-11-2008

20090139971Method And Apparatus For Welding With Mechanical Arc Control - A method and apparatus for feeding wire from a source of wire to a weld includes one or more motors disposed adjacent the wire to drive the wire to the weld. A buffer is disposed between the source and an arc end of the torch. Another motor may be disposed near the wire source. A wire tension controller may be provided. The one or more motors advance and retract the wire, and wire is stored, or the path length altered, when the wire is retracted.06-04-2009
20100089889Method And Apparatus For Controlling A Welding System - A method and apparatus for welding includes one or more of a welding type power source, a feedback circuit, a wire feeder and a controller. The controller preferably has an eta control circuit responsive to the feedback.04-15-2010
20110114612Method and Apparatus For Welding - A method and apparatus for welding include initiating a pulse welding process includes initiating a welding arc by providing CC type welding power, maintaining the arc by providing CV type power. Then, pulse type welding power is provided. The method and system can be used to start short circuit, or other welding processes by providing short circuit power, or welding power of a given mode, instead of providing pulse power. Also, in one alternative, a method and system of initiating a pulse, short circuit, or given welding process includes initiating a welding arc by providing CC type welding power at least until a pseudo-equilibrium for the arc is established. Then, providing welding power in a pulse, short circuit, or the given mode.05-19-2011

20100224606SHORT CIRCUIT DETECTION SYSTEMS AND METHODS - A constant voltage (CV) welding process power supply is provided. The power supply includes a controller configured to detect a short circuit event in a CV welding process and increase a welding current based upon a periodically computed voltage error and a first gain to attempt to clear the short circuit event. The controller is further configured to detect whether the short circuit event has cleared after the first current increase. If the short circuit event has not cleared, the controller increases the welding current based upon the periodically computed voltage error and a second gain higher than the first gain.09-09-2010
