摘要： An aircraft instrument landing system is disclosed wherein elevation angle measurements of an aircraft are derived by providing, in such system, a means for inhibiting an elevation swept beam of radiation from sweeping through ''''low'''' angles where significant multipath transmission is expected. Means are provided to vary the power in the transmitted beam of radiation in a predetermined manner as the beam is inhibited from sweeping. As a result the radiation received by the low flying aircraft is shaped in a way related to the shape of the received radiation expected without multipath transmission. Such arrangement enables the same aircraft receiver and processor to determine the elevation angles of both ''''high'''' and low flying aircraft without appreciable error.

摘要： A blender having two nested grindstones which meet along a frusto-conical surface and rotate with respect to each other about their common axis. The grindstones are of rough textured ceramic having perforations as large as 1/4 inch at the surface of each grindstone. Abrasion of the sewage material against the stones introduces new perforations and cutting edges. The design of the grindstones inhibits the clogging of the stones by metallic, ceramic, or plastic objects found in sewage and also inhibits jamming of the blender by long fibrous materials.

摘要： A dielectric body which is permeable to electromagnetic wave energy of a material selected from the group consisting of alumina and beryllia ceramics is provided with a coating of a semiconducting oxide to substantially suppress electron multipactoring. The exemplary materials include semiconducting oxides of silicon and transition metals including copper, cobalt, chromium, iron, manganese and nickel. Thicknesses averaging 1,000 Angstrom units have resulted in substantial increases in the power handling ability of electromagnetic devices employing such dielectric bodies.

摘要： An extended radiating aperture for X-rays is provided by means of a stationary target of a heavy metal positioned for uniform illumination by high speed electrons emanating from a cathode and accelerating through a difference of potential between the cathode and the target. The target is in the form of a relatively thin film which can be deposited on a substrate transparent to Xradiation. A layer of fluorescent material is placed adjacent the substrate on the opposite side thereof from the target so that Xrays generated within the target material pass through the target material and impinge on the fluorescent layer. The fluorescent material enhances the monochromaticity of the X-ray spectrum by emitting fluorescent X-radiation while substantially absorbing incident X-radiation having energies above the fluorescent radiation spectrum. A zone plate is positioned adjacent the fluorescent layer to spatially modulate the radiation of the radiating aperture to provide this radiation with a spatial frequency spectrum suitable for obtaining high resolution roentgenograms. The zone plate provides a coding on the roentgenogram which is then decoded by an optical processor to form a visible image of an object being X-rayed. Alternative embodiments of the invention include the use of an inclined transmissive target, a transmissive target having serrations, and the use of a moire pattern mask between the target and the fluorescent material to augment fluorescent radiation from the target and to inhibit the passage of X-radiation normal to the layer of fluorescent material.

摘要： A system of radiating elements arranged for forming one or more beams of radiation having radiation patterns such as a monopole, dipole, quadrupole, other multipoles or combination thereof. The individual radiating elements of the array are interconnected by circuitry providing for the summing and differencing of signals provided by adjacent radiating elements in response to incident radiation. In one embodiment the signal of one radiating element is delayed relative to the signal of an adjacent radiating element. The differencing of the signals provides for the deep nulls found in radiation patterns such as the dipole and quadrupole radiation patterns, while the delay between signals of adjacent radiating elements is adjusted for varying the shape of the directivity pattern. The system provides for varying the direction and shape of beams of the radiation pattern to provide for the detection, classification and/or tracking of a distant source of radiation as well as for illuminating a distant object. The system is responsive to the intensity of radiation received along one or more beams of the radiation pattern, and in response thereto, varies the delay between the signals of adjacent radiating elements and also provides for the selective coupling of specific radiating elements of the system.
