Abstract: A novel, improved plant support device universally adaptable for holding one or more upright plant-supporting masts substantially vertical in conjunction with a flower pot or other planter receptacle without penetrating the soil or disturbing plant root growth. The support mast can be readily mounted directly to or indirectly in conjunction with the rim portion of the receptacle by means of a pair of generally horizontal cross-disposed mast-traversing-and-supporting rods, each rod separately intersecting the lower base portion of the mast on closely vertically spaced levels, with the ends of the respective horizontal rods slipped through correspondingly provided holes or slots in the upper rim portion of the plant receptacle. Various rim hole and slot arrangements are disclosed to provide for a variety of differing dispositions of one or more of the masts relative to the receptacle's center and/or rim to readily accommodate varying plant stalk/stem locations therein.

Abstract: The Airborne Infrared Transmissometer measures the infrared transmission between a test target aircraft and a detection system. A transmitter is attached to an aircraft and emits a calibrated infrared beam. A ground-based, shipborne, or airborne receiver measures the transmitted signals in the exact same path between the target aircraft and the detection system. Data recording equipment can be attached to both the transmitter and receiver to measure the associated outputs.
