Abstract: A method is described that enhances the atmosphere of romance that surrounds the purchase and delivery of a gift of jewelry. Broadly, the present invention establishes a romantic “theme” for a particular item of jewelry. This theme is first presented either through promotional advertising or in-store advertising, in connection with a particular item of jewelry. The theme is continued at the time of delivery of the item of jewelry, and is further continued even after the delivery. Preferably, this theme is in the form of a fabled love story, such as the stories of Romeo and Juliet, Orpheus and Eurydice, Tristan and Isolde, Anthony and Cleopatra, as well as countless others. It should be appreciated that such a novel method for selling an item of jewelry effectively enhances the atmosphere of romance that surrounds the gift, thereby enhancing the demand for jewelry items sold in this fashion.

Abstract: This invention relates to an improvement in equipment for the adjustment of blades, particularly propeller blades of fans, turbines, and the like, and especially for propulsion plants on aircraft, adapted to be selectively shut-off in a low-resistance position, the improvement comprising means whereby said blades are selectively foldable out of the operating position thereof about pivot axes transversely to their longitudinal axes, whereby said axes being tangential with respect to a common base circle are inclined with respect to the axis of rotation of said propeller blades in dependence upon the degree of twist of the blades, so that the blades in the folded-in position thereof are positioned next to each other jointly as parts of an imaginary cylindrical or conical envelope surface having a helical path with respect to the longitudinal envelope surface axis.

Abstract: A TIG pipe welding method which employs two sets of machine guide surfaces on the pipe ends. First radially inner guide surfaces cooperate with a sensor coupled to the welding torch to continuously monitor the arc gap between the welding electrode and the weld puddle as the welding electrode moves around the circumference of the pipe. The second set of radially outer surfaces cooperate with a welding carriage to guide the carriage and welding modules around the pipe joint. The carriage is constructed to provide a sealed welding chamber surrounding the electrode. An additional flow of shielding gas is provided around the torch electrode of a TIG or hot wire TIG welding module to augment the normal gas shield.
