摘要： A new power tong for rotating tubular members for make-up (connection) and break-out (disconnection) operations. In one aspect such a tong has at least one movable jaw with a smooth surface gripping element thereon and pre-load apparatus for applying a pre-load force to a movable jaw so that the jaw does not slip on a tubular to be rotated and so it does not mark or damage the tubular. In one aspect the pre-load apparatus includes a first pre-load device at one end of a movable jaw for breakout operations and a second pre-load device at another end of the jaw for make-up operations. In one aspect a power tong which has unique smooth surfaced jaw inserts made, e.g., of aluminum. In one aspect a single pivotable pre-load cylinder, fixed to rotary, pivots for pivotable connection to one jaw or the other. This can be done manually or a powered smaller piston/cylinder may be used to pivot the pre-load cylinder. In one aspect a jaw unit which comprises a jaw holder and a jaw movable with respect to said jaw holder, characterized in that said jaw is slidably mounted on said jaw holder.

摘要： A welding shield includes a frusto-conical metal shield member, open at top and bottom, and including a wall opening for welding gun access. A lens is removably mounted in the top of the shield member, and a horizontal metal screen is removably mounted within the shield member between wall opening and lens. A circumferential base around the bottom is of a flexible and nonflammable material for effective closure around a weld work area. The work area is viewable, magnified, by the lens. The welding shield is lightweight for easy movement and placement by one available hand of the user.

摘要： A stringed musical instrument device that functions as a peripheral for a computer or computing device, whereby electronic transducers placed inside and/or outside the instrument convert the vibrations of the strings and/or the instrument body from an analog electrical signals to digital signals. The digital signals are then transmitted via Class Compliant USB and/or FireWire-IEEE 1394 and/or IEEE 802.11 wireless and/or Bluetooth® wireless protocols to any computer or computing device that accepts data via those protocols. This device requires no external power, amplification, analog-to-digital conversion, software or hardware. This device is an improvement over the prior art in that it accurately and immediately represents on a computer or computing device the signals that are being sent from the instrument and reduces the number of devices needed to accomplish the task of sending digital signals to a computer or computing device.
