Abstract: A method and apparatus for delivery of medicaments to oral tissues is provided. The apparatus operates on the principle of a vacuum pump such that medicaments are essentially sucked into spaces within the dental tissue upon reversal of pressure from negative to positive pressure. The apparatus comprises a resilient plastic material forming a frontal buccal shield, and dental trays for upper and lower dental arches. The device is operated by moving the jaw in a chewing motion after placing medicaments in the upper and lower trays.

Abstract: A hybrid engine is disclosed which utilizes the heat from the exhausted combustion gases of an internal combustion engine to generate steam externally of the cylinders of the engine. The steam is used to power turbines which may be effectively connected to augment the power supplied by the internal combustion engine or to act as a power transfer medium. The device includes a modified exhaust manifold which incorporates one way valves and water injection ports to enable steam pressurization within the manifold. Steam spent in the turbines is condensed and returned to the system with exhaust gases being vented to atmosphere subsequent to the utilization of their previously wasted heat energy for power production.
