Title: Preprogrammable recording system with automatic warning of time limit
IPC: G11B23/42
Filed: 1979-08-30
Abstract: A recording system for recording signals on a magnetic tape uses a recording apparatus and cassettes, each cassette containing a specific length of magnetic tape, and has a timer for setting time-preprogrammed automatic recordings. A detection unit determines the maximum time available for recording on a cassette placed in the apparatus and a comparator compares an output signal of the detection unit with a reference quantity which is a measure of the total time required for the preprogrammed automatic recording(s). When this required time exceeds the maximum time available for recording with this cassette, an alarm signal is produced. The cassette has marks which are sensed by the detection unit and which indicate the length of the magnetic tape in the cassette.

This allows the seed meter (10) to be removed in a direction transverse to the shaft axis regardless of the rotational position of the lugs. The driven lugs (66, 68) are spring biased to project axially. The spring may provide over-centre action so that the lugs are also stable when folded right down away from the driving lugs (56, 58), in a modified embodiment, the driving lugs (56, 58) also are pivotally mounted in the same way.
