Abstract: A hybrid air engine includes an engine block, a head with at least one precombustion chamber (head), at least one intake injector, at least one exhaust valve, a routing manifold, and an engine control module. The at least one intake injector, and the at least one exhaust valve are retained by the head. The precombustion chamber formed in the head includes a spark plug and a precombustion injector. A source of compressed air and a source for fuel is supplied to the routing manifold. The routing manifold directs the flow of the compressed air and fuel to the at least one intake injector and at least one precombustion injector. The engine control module controls the operation of the at least one intake injector, at least one exhaust valve, and other engine components.

Abstract: An insect-proof and tamper-evident cover is disclosed for a disposable, one-time use beverage container. A lid, non-rotatably secured to the upper end of the beverage container, includes an initially sealed lid opening, an arcuate groove housing a projection used to break the sealed lid opening, and a plurality of bearing surfaces. A rotatable cover is secured to said lid in a fluid-tight arrangement. The cover includes a fluid opening having parallel bars there-across, a plurality of finger engaging members, and a tamper evident indicator.

Abstract: An insect-proof and tamper-evident cover is disclosed for a disposable, metal, one-time use beverage container. A lid, non-rotatably secured to the upper end of the beverage container, includes an opening with bars formed there-across, and with a plurality of cover-supporting bumps and a position-controlling groove. A rotatable cover is secured to said lid in a fluid-tight arrangement. The cover includes an opening with bars there-across, at least one finger-engaging member, a tamper-evident indicator, and a projection arranged to travel in the position-controlling groove of the lid.
