Abstract: A method and apparatus for Flow Injection Analysis (FIA) into Atmospheric Pressure Ion sources (API) including Electrospray (ES) and Atmospheric Pressure Chemical Ionization (APCI) sources whereby the sampling and spray needles are one and the same. The sampling and spray needle configured with an autoinjector apparatus or used in manual injection is introduced directly into a mating ES or APCI probe configured in an API source. Such a sampling and spray needle eliminates the need for injector valves, transfer lines or additional fluid delivery systems in FIA into API sources interfaced to mass spectrometers or other chemical analyzers. The use of a sampling and spray needle configuration reduces component costs, liquid dead volume, sample dilution effects, and minimizes cross contamination effects, solvent consumption and waste while increasing sample throughput.

Abstract: A low light level system is described wherein electrons, created by images directed to a photocathode, directly bombard active pixel sensors. Both the active pixel sensors and the output end of the photocathode are positioned in a vacuum envelop. The electron released from the photocathode are directed to and at the active pixel sensors. The output of the active pixel sensor detector may be stored, viewed or displayed at a remote location. Various applications are described including a novel camera.

Abstract: In a beverage vendor, a cup capping mechanism in which a cap is removed from a remote location to a stationary cup station, placed on the cup and then pressed down onto the rim of the cup by a sliding motion over the upper surface of the cup beginning at one side and progressing to the other. A locking mechanism is provided which prevents opening of the cup station delivery door during the capping operation.

Abstract: A cover for a cup dispenser includes an indicating device which provides a warning when the dispenser is nearly empty. A weight at the end of a spring controlled wire reel mounted in the cover is placed in the uppermost cup and moves down as cups are dispensed. At a predetermined distance of travel of the wire and weight, a microswitch is actuated which connects a battery to turn on a light bulb or other warning or indicator device on the cover. When a new supply of cups is inserted, the weight is lifted and the spring rewinds the wire and opens the switch connecting the light and battery.
