    摘要： A folding work station includes a work surface and a frame supporting the work surface. The frame includes at least one rolling support and is selectively expandable to an open configuration, in which the frame supports the work surface in a working orientation, and foldable to a substantially flat closed configuration having a vertical orientation, in which the frame supports the work surface juxtaposed on the frame. In addition, the work station is movably supported on the rolling support(s).

    摘要： A shelving system includes a shelf mat and a support structure for supporting the shelf mat. The shelf mat includes an object carrying portion for supporting objects and a projection connected to and projecting from the object support portion. The support structure includes a pair of vertical corner posts each having two vertical rods spaced by a distance sufficient to permit the insertion of the projection therebetween but to prevent substantial horizontal movement of the projection when the projection is so inserted. The support structure also includes a horizontal support, connected between the two vertical corner posts, and adapted to support at least a portion of said shelf when inserted between the two vertical rods. Methods of manufacturing the shelf mat and support structure using continuous mat-forming steps are also described.

    摘要： A dual mode plasma arc torch is provided that preferably comprises a start cartridge disposed between an electrode and a tip. In one form, the start cartridge comprises an initiator that is in electrical contact with the electrode and that is resiliently biased into contact with the tip, such that when the plasma arc torch is in a contact start mode, the initiator is movable against the resilient bias to separate from the tip and establish a pilot arc between the initiator and the tip. Further, when the plasma arc torch is in a high frequency start mode, the start cartridge spaces the tip from the electrode such that a pilot arc is established between the electrode and the tip. In other forms, a contact start torch is provided that is operable under high frequency, and conversely, a high frequency start torch is provided that is operable under low voltage.

    摘要： A tip gas distributor is provided that preferably comprises a plurality of swirl holes and a plurality of secondary gas holes, wherein the swirl holes direct a plasma gas to generate a plasma stream, and the secondary gas holes direct a secondary gas to stabilize the plasma stream. Additionally, a tip gas distributor is provided that comprises swirl passages and secondary gas passages formed between the tip gas distributor and an adjacent component to generate and stabilize the plasma stream. Further, methods of generating and stabilizing the plasma stream are provided through the use of the swirl holes and passages, along with the secondary gas holes and passages.

    摘要： A contact start plasma arc torch is provided that comprises an electrode, a tip, and an initiator that is resiliently biased into contact with the tip, the initiator being movable against the resilient bias to separate from the tip and establish a pilot arc between the initiator and the tip. The initiator is disposed within a start cartridge, which preferably comprises a coil spring that biases the initiator into contact with the tip. The plasma arc torch further comprises a plurality of head vent holes to vent gas from within the start cartridge during operation of the torch. Additionally, the tip defines a plurality of swirl holes and secondary gas holes to generate and control a plasma stream that is subsequently blown from a central exit orifice in the tip.
