Abstract: Ink jet apparatus of the impulse type employs one or more peristaltic pumps. The pumps comprise a flexible tube extending between the ink reservoir and the jet. One tube is constricted so as to advance ink from the reservoir to the jet. Another tube is constricted so as to create a vacuum and return ink from the jet to the reservoir.

Abstract: An ultraviolet lamp is disclosed wherein the light source is a rapid pulse unconfined xenon arc tube containing more than three atmospheres of xenon gas pressure, and providing an output limited to wavelengths greater than 320 nanometers. Associated circuitry for operating the tube and associated light transmitting means for utilizing the output of the tube are also disclosed.

Abstract: A solid-liquid waste incinerator is disclosed which provides a novel thermodynamic interaction between a liquid catalyst, which is employed for cleansing the exhaust gases from the incinerator, and a combustion stage in which the solid-liquid wastes are burned, thereby reducing their volume by about ninety percent. Generally, solid-liquid wastes are introduced into a combustion chamber, and are initially heated by indirectly contacting molten salts or other hot liquid catalysts. A burner disposed directly above the wastes also heats the wastes to produce combustion of the wastes into exhaust gases and a greatly reduced volume of ash residue. During the combustion process, the burner, together with the heat produced from the combustion of the wastes, act to reheat the liquid catalyst.
