    摘要: A manual welding safety disconnect to provide the welder the ability to stop current flow to a TIG (GTAW) torch or a stick (SMAW) welding lead where it attaches to the supply cable which would allow the operator to prevent further current flow by causing a misalignment of the enclosed electrical contacts. Misalignment of the electrical contacts by a rotation around the inert gas tube permits the operator to immediately shut off the welding current while still allowing the gas flow in the TIG version. This configuration also is more convenient for the welder since he would not have to leave his work area. This safety device would reduce the risk of electric shock, accidental arc strike, and arc flash. This device can isolate any one lead or torch to produce a safe zero energy mode even if operating from a multibank power supply.

    摘要: An elastomeric load bearing surface with different load support characteristics in different directions. In one embodiment, the surface includes an elastomeric membrane that is oriented in only a single direction, for example, by compression or stretching. In another embodiment, the surface includes mechanical structures, such as connectors, variations in thickness and apertures, that vary the load support characteristics in different directions. In another aspect, the present invention provides a multilayer load bearing surface in which the layers cooperate to provide a controlled force/deflection profile that is variable in different regions of the surface. In one embodiment, the upper layer includes a plurality of loosely connected nodes and a lower layer having a plurality of resilient elements that separately support each node.
