Abstract: Response contrast of photoelectric processes is enhanced by selecting photoelectric systems having different rise times for different light input intensities, and by exposing the photoelectric systems during periods of time which are shorter than the rise time for a lower light intensity or which are at least as short as the rise time for a higher light intensity. Bright spot detection systems and magnetic imaging or recording systems employing these rise time phenomena are also disclosed.

Abstract: In a sealed-off neutron generator containing tritium, for the production of neutrons by the D-T reaction, helium-3 gas accumulates owing to radioactive decay of the tritium and interferes with the proper operation of the generator. In the present generator a sputter-ion pump is sealed to the generator to remove the helium-3 from the envelope prior to admitting hydrogen isotope gas from the usual replenisher before use. The pump is adapted to remove only the unwanted helium-3 and not the wanted D and T, by having its sputterable cathodes made of, or coated with, a metal which has a low chemical affinity for hydrogen but is readily sputtered by helium, such as copper.

Abstract: The luminescent screen collecting the photo-electrons of an imaging device is provided with a cover layer that decelerates the electrons so that luminescence occurs only if the photoelectrons have been accelerated to at least a quarter and preferably at least one half of the value of the nominal operating voltage thereby increasing the control range of the permissible intensity variations within the acceptable image definition limits of the device.

Abstract: The instant invention involves a system for generating high current density charged particle beams. The system includes a plurality of high intensity ion sources in combination with two charge exchange cells aligned linearly with one another. The ions are converted from one type of charge to an opposite charge in two stages. In the first stage, several beams of positive ions, for example, derived from a plurality of positive ion sources are beamed into a charge exchange cell and converted into neutrals. The several beams of neutrals from the first cell are then directed into a second charge exchange cell where the neutrals are converted into negative ions.

Abstract: Subterranean sandy and silty sedimentary formations are examined to determine that mineral crystals, known to grow most favorably in alkaline, saline conditions that typify a marine depositional environment, are authigenic, i.e. formed in place, in the sedimentary formation. This indication of the nature of the depositional environment is useful for further exploration by geologists in seeking the presence of petroleum deposits.

Abstract: An infrared detection system for discriminating between point sources and extended sources of infrared radiation is disclosed wherein a pair of detectors are provided with control electrodes which are energized with quadraturely phased driving voltages to provide information on the coordinate position of any radiant energy image falling on the detectors. In front of each detector is a stationary reticle having a checkerboard pattern of areas opaque and transparent to infrared radiation. One checkerboard is the reverse of the other. The outputs of the detectors are combined in a differential amplifier. When an image from an extended radiation source is focused on the reticles, it covers several of the individual squares of the checkerboard design and similar signals are produced which cancel out in the amplifier. A point source target, in contradistinction, passes through only one of the reticles and, consequently, its signal does not cancel in the amplifier.
