摘要： A conveyor roller assembly comprising a supporting bracket through which the roller assembly can be fixed in use, a hollow, generally cylindrical roller shell supported for rotation about its longitudinal axis on the bracket, an electrical generator housed within the roller shell and driven thereby by rotation of the shell to produce an electrical output, a brake within the roller shell and operable to brake rotation of the shell relative to the bracket, a speed sensor within the shell for sensing the speed of rotation of the shell relative to the bracket, and, an actuator powered by the electrical output of the generator when the speed sensor detects that the speed of rotation of the shell relative to the bracket exceeds a predetermined value, to effect operation of the brake to brake rotation of the shell.

摘要： An angle servo preamplifier for use in the tracking antenna servo drive sem of a precision tracking radar system. The angle servo preamplifier processes tracking error signals indicative of tracking antenna pointing errors with respect to a target. The preamplifier is comprised of an input differential amplifier stage, a phase control stage, a sample and hold stage and a power amplifier stage. In addition, interfacing circuitry is included for coupling the preamplifier to the azimuth/secant correction system of the tracking radar system. The sample and hold stage includes "deglitching" circuitry for suppressing sampling/switching transients. And, to accommodate a bipolar tracking error signal while utilizing a single voltage supply, the power amplifier stage performs d.c. level translation.

摘要： A direct coupled linear amplifier which employs negative feedback to prov accurate and stable gain to AC as well as DC input signals. It also performs the function of a DC level shifter and can therefore be interfaced with a variety of signal sources. A constant current source added to the summing junction of the negative feedback amplifier enables the adjustment of the DC level of the output and the AC gain of the amplifier, completely independently of one another.

摘要： A device for electronically correcting detected traverse error data from aracking radar antenna and receiver so that the azimuth error signal used to drive the positioning devices for the radar antenna are proportional to the true azimuth angular error. The traverse error signal produced by the radar is adjusted for various elevations by a correction factor which is generated from the detected elevation angle and proportional to the secant of that angle.
