Abstract: A bifunctional antenna of a primary/secondary radar system comprises a reflector having a concave front surface formed with a row of slots along a horizontal generatrix, the slots lying in front of respective cavities excitable to radiate interrogation signals in a directive sum pattern and supplemental radiation in a differential control pattern designed to blank minor lobes of the interrogation pattern. Some of the cavities and slots are symmetrically duplicated on a dielectric cap covering the convex rear surface of the reflector. The reflector and its cap form a closed shell of dielectric material, specifically a glass mat impregnated with epoxy resin, overlain at the front by a fiber-glass fabric incorporating orthogonally intersecting insulated copper wires. The fabric also lines the inner walls of each cavity which is filled with dielectric material; its radiating slot is spanned only by horizontal wires paralleling the plane of polarization of target-seeking radiation from a source illuminating the reflector.

Abstract: The circuit arrangement monitors operating conditions of a group of direct current devices. The operating conditions are represented by different potentials occurring at a sampling connector of each direct current device. A first and a second selector unit, each having parallel signal inputs, are arranged symmetrically with respect to commonly connected outputs. Signal inputs of the first selector are connected to corresponding sampling connectors of the DC devices. A control unit for generating a control signal train has an output which is commonly connected to control inputs of both selector units. Commonly grounded filter capacitors are connected to the signal inputs of the second selector unit. A comparator is connected by a first input to a reference voltage source and by a second input to the outputs of both selector units. At the output of the comparator there is delivered a rated output signal evaluating the potential at the presently selected sampling connector with respect to said reference voltage.

These compounds are curable in the same manner as standard polysulfide polymers to form firmer polymers. The partially arylamine-terminated polymers may also be chain extended using isocyanate-terminated urethane prepolymers. These block copolymers may be cured by standard SH-terminated polysulfide polymer curing methods to prepare sealants of exceptional resiliency and weather resistance.
