Abstract: An improved composition for use as a liquid vehicle in ink systems and for printing on diverse substrates. The functional constituents of the compostiion are unsaturated fatty acid esters, difunctional or multifunctional acrylate esters and optionally mixed esters of unsaturated fatty acid and difunctional or multifunctional acrylates and other alpha, beta unsaturated carboxylates. Lithographing ink vehicle formulations of these improved components exhibit exceptional performance. In application, the improved compositions permit a substantial reduction or elimination of solvents and certain drying agents that otherwise form toxic and environmentally sensitive byproducts.

Abstract: The addition of an organophosphato-titanate and an organophosphato-zirconate to printing ink improves the adhesivity of the ink to a variety of substrates. A concentrate of the two organo-metallic components may be added to a conventional ink or added to the ink formulation during the ink's initial preparation. In addition to improving adhesivity, the additives reduce drying time, permit more rapid processing, and minimize the need for solvent diluents.

Abstract: Apparatus is disclosed for achieving improved dental anesthesia utilizing electronic stimulation applied through electrodes positioned inside the mouth of a patient. Each electrode includes an insulating base of foam material with an adhesive at one side thereof to retain one end of an electrical lead in contact with an electrically conductive elastomer, which elastomer has a surrounding outer layer of adhesive for maintaining the elastomer positioned inside the mouth of a patient. A transcutaneous nerve stimulator is utilized to generate the stimulating output signal, which signal may be a pulsed DC signal, an AC signal, a pulsed DC signal followed by an AC signal, or various other combinations of such signals, and the pulsed DC signal is offset to a fixed quiescent DC level above a zero voltage reference when applied to the patient.

Abstract: A trailer adapted to be towed by a prime mover supports at least one batting platform adapted to be stood upon by baseball players, one in each of a plurality of batting areas. A plurality of pitching machine, supported by the prime mover positioned a distance from the batting areas, the prime mover being positioned to project a plurality of baseballs into the batting areas to permit hitting of the baseballs by the players. A structure including poles and cables supports a flexible material around at least the batting areas to provide an enclosure for restraining to a limited area the baseballs pitched by the machine and hit by the players. The batting areas can be transversely aligned at one end of the trailer in which case the pitching machine is positioned in proximity to the other end of the trailer. The batting areas can also be aligned along the length of the trailer in which case the pitching machine is positioned laterally of the trailer.
