Abstract

1311047 Educational appliances COMPAGNIE INDUSTRIELLE RADIOELECTRIQUE 19 April 1971 [17 April 1970] 9846/71 Heading G5G [Also in Division H1] A language laboratory installation has a non-magnetic panel 1 covering magnetically actuatable contact units behind respective zones 3 marked on the visible side of the panel. The panel forms part of a teacher's desk and has two zones 3 for each pupil work station and the contact units of each can be operated by a permanent magnet in a separate tubular pencil-like member (not shown) which the teacher can use as a pointer. Operation of the left-hand zone contact unit of any pair enables the teacher to listen in to the pupil at the work station whilst operation of the right-hand zone contact unit enables the teacher to speak to the pupil and control operations at the work station. Contact units under zones 4, 5, 6, 7, 8 and 9 influence the recording, stop, playback, rapid rewinding, forward winding and communication circuits respectively. The contact unit under zone 10 permits resetting of other contact units.
