Radiographs are generated in an apparatus comprising a fine mesh screen coated with an X-ray sensitive photoconductor by exposing said screen to an X-ray image while said coated screen is in physical contact with an insulating charge-supporting member and while an electrical potential is applied between the screen and an electrically conducting plate located on the side of the insulating member which is opposite the side the coated screen is on, and thereafter electrostatically toning the latent...

A process for gasifying waste material and producing energy which comprises contacting a solid organic waste material containing at least 10 weight percent oxygen with steam in the presence of an alkali metal carbonate catalyst at an elevated temperature to obtain a gas, combusting at least a portion of said gas to obtain combusted gases, and expanding the combusted gases through a turbine to rotate the turbine. Preferably, the energy of the rotating turbine is used to drive an electricity gener...

Unsolvated aluminum hydride is decomposed by a controlled heating method to yield pure hydrogen useful in chemical lasers and as an energy source.

In order to automatically add measured amounts of a catalyst or other substance to a chemical reaction as needed, a signal representing a specific reaction condition is utilized to generate a pulse which has a width representative of the magnitude of said signal. An integrator then adds the pulses and after a predetermined total pulse time triggers an actuating mechanism which performs the operations necessary to add a substance to the chemical reaction.

A method of controlling the rate of generating steam by direct heat exchange is provided in which a spray of hot oil drops contacts a spray of water drops. Large water drops are prevented from entering the effluent oil stream during upsets in operating conditions by providing suitable disengaging means such as heated sloped baffles below the contacting zone.

A tank contains water heated by a heat pump having a heat exchanger part in a waste-water reservoir or in a waste air conduit and a further heat exchanger part in the water of the tank, heat being picked up in the reservoir or conduit and delivered to the water in the tank. The latter is a closed tank and the space above the water is connected to the inlet of a motor-driven centrifugal turbine. The lower pressure thus formed above the level of the water by the turbine inlet causes evaporation of...

A collection device for energy from water with wave motion has working fluids, a number of pumping units and accumulators interconnected together, and valves to regulate the fluid flow. Each pumping unit has a chamber with an intake port connected to an accumulator, an exhaust port connected to another accumulator, and an outlet to the water. The working fluid in the chamber is in contact with the water, or is partitioned from the water by a flexible membrance or a piston. The pressure from the ...

A vector generator includes a linear charge pump in the form of a DAC with a constant but variable current output that can charge a capacitor connected between the output and one of the input terminals of an operational amplifier. A second constant current generator having an output current one-half that of the maximum output current of the DAC and of opposite polarity also is provided for charging the capacitor, the constant current generators being so connected to the capacitor that it can be ...
