An electric arc welder for performing a pulse welding process by a current between an advancing electrode and workpiece where the welder comprises a short detecting circuit for creating a short signal upon occurrence of a short circuit between the advancing electrode and the workpiece and a boost circuit to create a plasma boost pulse after the short circuit is cleared during the time period when the welder is not outputting the peak pulse current.
摘要:
A clamp assembly for bone fixation elements including first and second clamp structures configured to engage first and second bone fixation elements, respectively. The first clamp structure may have a first spherically contoured bearing surface. The second clamp structure may have a second spherically contoured bearing surface seated in sliding contact with the first bearing surface. A spring-loaded mechanism may apply a spring force urging the bearing surfaces together to resist pivotal movement of the clamp structures relative to each other. The clamp assembly may be used with an assembly of fixation elements to create an external fixation frame.

The disclosed cranial flap clamp includes first and second clamping members and an extension member. A portion of the first member is positionable against inferior surfaces of a bone flap and skull and a portion of the second member is positionable against superior surfaces of the flap and skull. The extension member extends from the first member through the second member and fits between the flap and skull. Movement of either of the clamping members urges the inner surface of the first member against the inferior surfaces of the flap and skull and urges the inner surface of the second member against the superior surfaces of the flap and skull. The securing instrument includes features useful in cutting or crimping the extension member. The tension limiting assembly provides variable designs and combinations for limiting the tension placed on, and exerted by, the securing instrument during use.
摘要:
The invention described herein generally pertains to a system and method for welder system that relates to creating a welding sequence for a welding environment in which the welding sequence is based upon non-real time data collected from a welding procedure. Welding procedure information is collected and utilized to create a welding sequence to perform two or more welds in which at least one parameter is based on the collected welding procedure information (e.g., non-real world welding procedure).
摘要:
The invention described herein generally pertains to a system and method for collecting one or more welding parameters in real time during creation of one or more welds using a welding sequence. The one or more welding parameters can be associated with a particular welding sequence. Moreover, based on the one or more welding parameters collected, a modeled welding parameter can be generated to increase quality, efficiency, and the like. A collection component collects real time welding parameter data from which a quality manager component creates a modeled welding parameter. The modeled welding parameter can be employed for the welding sequence to monitor or track the welding parameter during a subsequent weld.

A sternum fixation device for securing parts of a sternum includes first and second removably associated plates. The first plate has an upper surface and a sternum-contacting surface, and at least one hole passing through both of these surfaces for receiving a fastener head. The second plate has at least one attachment member for fixation to the sternum. A release member holds the first and second plates together, and is movably associated with at least one of the first and second plates such that it may be moved to allow separation of the two parts of the sternum.
