    摘要： A thermopile radiation detector is provided consisting of a series of differential thermocouples with all junctions spaced and thermally insulated from their support, thus making all junctions active. By providing spaced rows of thermopiles with junctions at different intervals, each forming a separate digital channel, a variety of codes can be produced. If a beam of uniform radiance is projected onto the array of detectors, a different signal is generated for each given position of the radiation edge in the field of view of the thermopile. This is useful for edge detecting applications.

    摘要： A device for delivering anhydrous ammonia to the soil so as to provide substantially uniform treatment of the soil which comprises a conduit or delivery pipe connected to a supply of anhydrous liquid ammonia through a valve which is opened for a set pre-determined period of time by a time switch. Means are provided for actuating the time switch at times spaced in proportion to the rate of movement of the apparatus over the soil.

    摘要： An improved liquid-bath-type reference cavity is provided, in which the cavity is formed by a closed-end metallic bellows. The walls of the bellows are fabricated from good thermal conducting materials with very thin wall thickness, which increases the effective surface area in contact with the liquid and provides a rapid stabilization of the cavity to the temperature of the liquid bath in which it is immersed.

    摘要： A passive intrusion detector is described with two stationary detectors or detector elements arranged side by side and stationary optics which image a target onto the plane of the detector. The output of the two detectors or detector elements, which are in opposition, is processed in electronic circuits involving differentiation so that there will be no final output unless the image of the target moves onto and off a detector or, in one modification, from one detector to the other. The electronics can also indicate the direction of the movement. The detector is aimed at an area where an intruder may enter, for example, a path through the jungle, and signals by the infrared radiation of the target that moves into the area or across it actuate an alarm.

    摘要： A horizon sensor of the radiation balance type is described with an earth tangency mask so that the horizon sensor detectors are illuminated only by a narrow band of radiation at the horizon of the earth''s disc when the horizon sensor is positioned for correct vehicle attitude.
