Abstract: A family of ultra high-energy gun propellant systems based upon a nitrocellulose binder matrix, and containing a variety of azide components to provide a formulation having reduced isochoric flame temperatures and ultra-high mass impetus.

Abstract: Elongated straight cylindrical metal rods are threaded along opposite end portions, and the cylindrical outer surface of the center portion of each rod is marked to form a visual indicator of the longitudinal center of the rod. The straight rods are successively inserted into a rod bending machine having a mandrel with a mark indicating the center plane of the bending operation. The mid-point mark on each rod is aligned with the center plane mark on the machine, and the rod is bent to form a precision U-bolt. Preferably, the mark identifying the center of each rod extends circumferentially around the metal rod and is formed by a stripe of color contrasting ink directly on the rod or on a label attached to the rod to provide a permanent mark which does not require rotating the rod to find the mark.

Abstract: An impeller is positioned within the flow of a fluid to be used to irrigate an area. The impeller drives a generator, which operates to charge and sustain a storage battery. The battery powers a receiver having an identification code by which the receiver may be addressed to receive commands, such as, for example, to open or close a valve, thereby providing fluid to irrigate an area. By opening the valve, the fluid flow is increased, and more power is generated and stored in the battery. In this way, power is generated automatically for the receiver, which, in turn, controls the fluid flow for irrigation.

The straight rods are successively inserted into a rod bearing machine having a mandrel with a mark indicating the center plane of the bending operation. The mid-point mark on each rod is aligned with the center plane mark on the machine, and the rod is bent to form a precision U-bolt.
