A device for locating and distending the external jugular vein is provided by a wish-bone shaped apparatus designed to engage the neck of a patent and apply sufficient pressure on the neck that the external jugular vein becomes distended due to pressure placed on the patient's neck. The device includes two distally placed flat portions that resiliently engage the patient's neck without causing choking or hindrance in breathing.

Apparatus and method for providing IV access to the external jugular vein

A blade tip cap of a turbine blade is repaired by restoring the tip rail and attaching a strengthening rib across the blade tip cap connecting the concave wall to the convex wall of the tip rail.

Method of repairing a turbine blade tip

A maskant is provided for use during laser welding or drilling comprising a paste of metallic powder and silica.

Maskant for use during laser welding or drilling

A method for repairing a turbine blade (,) wherein the tip (,) of the blade is removed (,) and a replacement cap is attached by welding (,). The cap may consist of a plate (,) attached by welding and a squealer (,) formed by depositing weld material (,), as illustrated in FIG. 3. The plate and/or squealer may be formed from a material different from the material of the airfoil portion (,) of the blade in order to optimize the performance of the blade.

A process is provided for welding a nickel or cobalt based superalloy article to minimize cracking by preheating the entire weld area to a maximum ductility temperature range, maintaining such temperature during welding and solidification of the weld, raising the temperature for stress relief of the superalloy, then cooling at a rate effective to minimize gamma prime precipitation.

Welding superalloy articles

A process is provided for laser welding a nickel or cobalt based superalloy article to minimize cracking by preheating the entire weld area to a ductile temperature, maintaining such temperature during welding and solidification of the weld, with the welding utilizing a powder alloy feed and the speed of the laser controlled to less than 10 inches per minute.

Laser welding superalloy articles

A protective gas shroud for welding is provided by: positioning an article into a chamber having an opening at the top to permit welding of the article; introducing argon into the body of the chamber to act as a protective gas shroud for the article during welding; introducing helium into the open top of the chamber to assist in maintaining a protective gas shroud around the article during welding; and welding the article within the protective gas shroud.
