Abstract: A dual-filament light bulb with associated adapter apparatus which uses photovoltaic cells mounted within the light bulb to charge a battery which powers one of the filaments. The adapter apparatus is designed to mount in an ordinary light socket which provides external current to the other filament. The adapter apparatus includes circuitry which alternately switches from the filament powered by the battery to the filament powered by external current in a manner which reduces the amount of electricity needed to produce a given amount of light.

Abstract: A portable electronic timepiece and radiation monitor assembly formed by a timekeeping section so linked to a radiation monitoring section that the user is provided not only with a time display but also with a reading of the existing level of penetrating radiation to which he is exposed. The timekeeping section includes a stable, high-frequency time base from which is derived low-frequency timing pulses that serve to actuate an analog or digital time display. The radiation monitoring section includes electronic means such as a microprocessor coupled to a radiation detector yielding signal currents or pulses at a rate depending on the existing intensity of radiation. These electronic means are responsive to clock pulses from the timekeeping section to determine the number of radiation pulses yielded within a fixed time interval to provide a radiation intensity value whose magnitude is indicated on a radiation intensity display.

Abstract: A container having an articulated closure for an opening in the lid in which one end of the closure is mounted on the lid adjacent the inner end of the opening, a closure element is hinged to the mounted end and overlies the opening to seal the contents and a lift element is integrally formed on the closure element opposite the mounted end to lift the closure element pivotally relative to the mounted end to provide access to the opening for the discharge of the contents of the container.

Abstract: A container having a slide closure accommodated in a guideway recessed beneath the upper surface of the lid in which the guideway is defined between a pair of parallel walls depending from the upper surface of the lid connected by a recessed portion of the lid and in which the slidable closure moves within the guideway from a position closing an opening in the recessed portion of the lid to an open position.

Abstract: A container having an articulated closure for an opening in the lid in which one end of the closure is mounted on the lid adjacent the inner end of the opening, a closure element is hinged to the mounted end and overlies the opening to seal the contents and a lift element is hinged to the closure element to pivotally lift the closure element and fold it back to provide access to the opening for the discharge of the contents of the container.

Abstract: A rigid container having an opening in a rigid lid thereof, a slidable cap recessed beneath the upper end of the container movable into position over said opening in the lid, and a seal on the lid and cap to provide an easy-to-open sealed closure which cannot be removed from the lid or dropped into the container.

Abstract: Solar radiant energy and high-intensity light are converted to electrical energy to supply electrical power for propelling vehicles in a safe, economical and efficient manner.The radiant energy can be beamed from outer space by the use of satellites with collecting surfaces which can produce and store electrical power and which can distribute the electrical power to earth stations for redistribution to high-intensity light sources. High-intensity light-receiving cells or panels are fixed to the surface of a vehicle to collect the high-intensity light and to convert the light into useful electric power to operate the vehicle. Energy can be stored in batteries for subsequent use.A vehicle can also be powered by hybrid means including solar cells and gas turbines.
