    • A current path for a mig welding gun assures a reliable and stable interface between a welding gun and a weld wire. In one embodiment, the current path is through a conductive insert that fits in the welding gun diffuser. Fingers of the insert resiliently contact the weld wire and thereby provide stable paths for welding power from the gun to the weld wire. In another embodiment, a contact tip assembly comprises a contact tip having resilient fingers in electrical contact with a body. An inner frusto-conical surface of a sleeve is urged against concentric frusto-conical outer surfaces of the fingers to bias the fingers radially inwardly against the weld wire. An insulative liner in the contact tip guides the weld wire between the fingers. A shield surrounds the contact tip and the sleeve. In a further embodiment, a single finger is pivotally connected to the contact tip. A spring biases a finger end against the weld wire. In an alternate embodiment, the finger is wedge shaped and is held in an angled slot in the contact tip.
    • 电焊枪的电流路径确保焊枪和焊丝之间的可靠和稳定的界面。 在一个实施例中,电流路径穿过配合在焊枪扩散器中的导电插入件。 插入件的手指弹性地接触焊丝,从而提供用于焊接从焊枪到焊丝的动力的稳定路径。 在另一个实施例中,接触尖端组件包括具有与身体电接触的弹性指状物的接触尖端。 套筒的内截头圆锥形表面被推压到指状物的同心的截头圆锥形外表面,以将指状物径向向内偏压抵靠焊丝。 接触尖端的绝缘衬垫引导手指之间的焊丝。 护罩围绕接触尖端和套筒。 在另一个实施例中,单个手指枢转地连接到接触尖端。 弹簧将手指端偏压在焊丝上。 在替代实施例中,手指是楔形的并且保持在接触尖端中的成角度的槽中。

    • Apparatus for sensing temperature and/or strain in an object includes a broadband light source (1), connector means (2) in the form of an optical circulator or an optical coupler to which at least two substantially identical optical fiber Bragg gratings (4, 5) are connected. Grating (4) receives the broadband light from the connector means (2) and functions as a sensor of temperature and/or strain in an object. Light is reflected back from the grating (4) to the connector means (2) and then passed to the grating (5) which acts as a reference grating through which a light output signal is transmitted to a detector (8) which is conveniently a photodetector. Means are provided for chirping the two gratings (4, 5) at the same bandwidth and the detector (8) measures the intensity of the received light output signal, with the intensity being monotonically related to the change in temperature and/or strain sensed by the grating (4) in the object.
