Abstract | An adjustment device for aligning a group of cyclically switched transmitters or receivers with a single receiver or transmitter of the kind in which a series of spatially spaced beams pass between the transmitters and the receiver, or alternatively between the transmitter and the receivers. In a preferred form the adjustment device is used to ensure alignment of a row of infra-red transmitters which direct beams of light to a photoelectric converter arranged at the focus of a concave mirror. The adjustment device features a coincidence circuit the outputs from which indicate that signals transmitted from the end transmitters of the row are received at the photoelectric converter. The outputs are used to energize respective adjustment indicating lamps. In a particularly preferred arrangement threshold circuitry is used to produce winking of the lamps when approximate adjustment has been achieved; continuous lighting of the lamps shows that accurate adjustment is present. The lamps can conveniently be placed adjacent their associated transmitters. |
