Abstract: An animal watering system includes a storage device, that has a bottom, a top, a mouth located within the top, and a plurality of sides, and a drinking device that is designed to dispense a liquid and to receive the bottom of the storage device. The storage device includes a selectively openable and closable port system and a sealing mechanism for sealing the mouth of the storage device. A method of using an animal watering system is also provided. The method includes the steps of placing a first cap on an orifice in the storage device, filling the storage device with a liquid through a top of the storage device, sealing the top of the storage device, placing the storage device within the drinking device, and removing the first cap from the orifice.

Abstract: Metallated graphite filament-wound structures are prepared by coating a continuous multi-filament carbon yarn with a metal carbide, impregnating the carbide coated yarn with a polymerizable carbon precursor, winding the resulting filament about a mandrel, partially curing the impregnation in air, subjecting the wound composite to heat and pressure to cure the carbon precursor, and thereafter heating the composite in a sizing die at a pressure loading of at least 1000 psi for graphitizing the carbonaceous material in the composite. The carbide in the composite coalesces into rod-like shapes which are disposed in an end-to-end relationship parallel with the filaments to provide resistance to erosion in abrasive laden atmospheres.

Abstract: Graphite is joined to graphite by employing both fine molybdenum powder as the brazing material and an annealing step that together produce a virtually metal-free joint exhibiting properties similar to those found in the parent graphite. Molybdenum powder is placed between the faying surfaces of two graphite parts and melted to form molybdenum carbide. The joint area is thereafter subjected to an annealing operation which diffuses the carbide away from the joint and into the graphite parts. Graphite dissolved by the dispersed molybdenum carbide precipitates into the joint area, replacing the molybdenum carbide to provide a joint of virtually graphite.
