Abstract: A semi-automatic brazing apparatus having a brazing wire feeding apparatus containing a brazing wire feed mechanism, a controller, and a user input device. The brazing wire from a brazing wire source is continuously drawn from the source through the apparatus via the feeding mechanism and is directed towards a brazing gun for a semi-automatic brazing operation.

Abstract: A lockable leveling structure has a vertical stand with a base at one end. The stand has legs pivotally attached and can be locked in a stable manner by a slide collar and thumb screw. The slide collar is movable about the vertical stand and makes a solid contact against the end of the legs causing the outer end of the legs to move up or down respective to one another to compensate for an unlevel support surface. This provides a solid motionless structure that can carry a load bearing fixture in desired degree of levelness in a safe, stable, novel manner without the use of shims, or altering the surface while on unlevel surfaces. The slide collar is unlocked and raised up the stand member allowing the bottom of the legs to rotate up toward the vertical stand member causing the structure to be in a compact package for storage or transport.

Abstract: An improved sawhorse has a horizontal central member supported at each end thereof by a special support assembly. Each of the support assemblies have a hinge formed at an upper end thereof by which it is hinged to the marginal end of the horizontal member. Each support assembly is foldable towards one another from a rigid, load bearing configuration into a storage configuration to present a small compact package for storage. Each of the support assemblies comprises a bracket at the upper end thereof which is attached to opposed marginal ends of the horizontal member; and an extension member is pivotally attached to the bracket. A latch device is included for latching and unlatching the extension member to the bracket. The support assembly terminates in a base at the lower end thereof, and includes a pair of diverging legs.

Abstract: A low temperature, lead-free, cadmium-free solder for joining metals, primarily copper tube or brass pipe and fittings. The solder composition, being free of lead and other known toxic metals, has a composition range of 0.5-4.0% antimony, 0.5-4.0% zinc, 0.1-3.0% silver, 0.1-2.0% copper and 86.8-98.8% tin, is especially adaptable for plumbing applications where solder joints are exposed to potable water.
