Abstract: A torch ignition apparatus and method, the apparatus including a secondary, torch ignition piston interconnected to the primary piston and operable to produce through compression ignition of a carbureted fuel/air mixture a jet of hot gases capable of igniting a fuel and air mixture compressed in a primary combustion chamber by the primary piston. The apparatus also includes a secondary fuel system for supplementing a low ratio fuel/air mixture in the combustion chamber and a novel hoop valve and exhaust port system for providing a unique, highly efficient flow-through system for exchanging gases in the combustion chamber.

Abstract: Improvements are set forth in connection with analgesic and antifebritic or antipyretic compositions, tablets with solid medicaments, and methods of preparing such compositions and tablets. Medicament particles, such as aspirin particles, for instance, and pectin or gum particles are included as main constituents in mixtures in which the pectin or gum serves to prevent undesirable side effects and in which coated and uncoated or exposed surfaces of medicament, or specifically aspirin, particles can be proportionately varied to vary or extend periods of medicinal activity of the medicament, or aspirin. In the methods of preparation, water can be included with or without water carriers and proportioned in a mix to soften the pectin or gum while maintaining the mix in a pourable state. On compression, a mix can be readily formed into tablets.
