  • Publication number: 20090223403
    Abstract: A warhead delivery system (25) including a multi-hydrogen bomb warhead (5) preferably having a plurality of bombs (3) located behind a door (2) of a nose cone (1) of the warhead (5). A plurality of decoys (4) may be used in conjunction with the bombs (3). The bombs (3) and decoys (4) are spring-ejected from the nose cone (1) through the doors (2). However, the bomb (3) may be transported via missile or via alternative delivery systems (23), such as aircraft (19), the back of a pick-up truck (6) or via flat-bed trailer (21).

  • Patent number: 5544610
    Abstract: A cargo submarine has a cargo section (2) between tapered peripheral buoyancy sections (2-5) and an on-board cargo-handling components (32-49) capable of rapid loading and unloading of large volumes of cargo. A hydrodynamic tower (14) conveys fresh air in and exhaust gasses out while traveling submerged sufficiently deep to avoid wave undulation. Dual electronic controls (51-57) in a tower bridge (27) and in a main bridge (50) are provided for large vessels. A crane (32) with automatically-adjustable weight balancing and electronic controls is telescoped from within the vessel. A shore ramp (47) and a ship ramp (44) are provided for fast and convenient motorized or manual handling of commercial or military cargo at beaches and shores without docks. Special hydrodynamic configuration and contouring result in less drag-per-length coefficient of marine vessels, resulting in less ton-mile propulsion costs than for optimized displacement-hull ships.

  • Patent number: 5072346
    Abstract: A light-condensing reflector positioned at the opposite side or end of a light source from a primary paraboloidal reflector in opposed reflector-to-reflector relationship to amplify light. The light-condensing reflector is selectively smaller in diameter than the primary reflector such that an annular or ring-like light orifice is formed between the outside periphery of a base of the light-condensing reflector and the inside periphery of a base of the primary reflector. Light amplified and condensed by the two opposed reflectors is collimated in an annular light beam through the annular light orifice. When applied to flashlights, spotlights and vehicle headlights, this invention increases the light intensity substantially.
