Abstract
Abstract Disclosed is apparatus for use in evaluating dialogues in a teacher-pupil or panel-class situation. An observer-operated keyboard activates different ones of various parallel-connected tank circuits of an oscillator means, to generate signals of different frequency, dependent upon the keys depressed. The frequency signals are recorded, as on magnetic tape. The output portion of apparatus comprises an analyzer composed of a plurality of filters tuned to individual ones of the different frequencies recorded, along with appropriate display or print-out equipment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
Apparatus for use in evaluating a dialogue comprising, in combination: keyboard means comprising a plurality of individual keys each bearing indicia, said keys being actuable to produce discrete electrical pulse signals each of which is indicative of an event occurring in a dialogue and the person engaged in the dialogue to which the event is ascribable, at least some of said signals identifying the nature of spoken words by persons engaged in the dialogue, means for storing said electrical signals in the sequence in which they occur, means for counting the number of times that said discrete electrical pulse signals occur during a dialogue and hence the number of times that the events corresponding to those signals occur during the dialogue, and means coupled to said counting means for displaying the number of times that selected ones of said stored signals representing events have occurred during a dialogue and the persons to which such events are ascribable to enable a determination of the characteristics of said dialogue.
Claim 2
Dependent Claim
167 words
Apparatus for use in evaluating a dialogue comprising, in combination: keyboard means comprising a plurality of individual keys each bearing indicia, said keys being actuable to produce discrete electrical pulse signals each of which is indicative of an event occurring in a dialogue and the person engaged in the dialogue to which the event is ascribable, at least some of said signals identifying the nature of spoken words by persons engaged in the dialogue, means for storing said electrical signals in the sequence in which they occur, means for counting the number of times that said discrete electrical pulse signals occur during a dialogue and hence the number of times that the events corresponding to those signals occur during the dialogue, and means coupled to said counting means for displaying the number of times that selected ones of said stored signals representing events have occurred during a dialogue and the persons to which such events are ascribable to enable a determination of the characteristics of said dialogue.
Claim 3
Dependent Claim
21 words
Apparatus as defined in claim 1, characterized in that said display means includes a tape-punch means and a computer-controlled electric typewriter.
Claim 4
Dependent Claim
43 words
Apparatus as defined in claim 1, characterized in that said display means includes an array of counters each of which is responsive to a selected one of said discrete electrical signals for indicating the number of times that said discrete electrical signal occurs.
Claim 5
Dependent Claim
76 words
Apparatus as defined in claim 3, characterized in that said array of counters comprises a plurality of odometers arranged on a panel, and including a plurality of view plates each of which is adapted to be placed over said panel and is provided with selected cut-out portions which expose only selected ones of said odometers whereby the number of times that only selected ones of said electrical signals occur will be viewed through said view plate.
Claim 6
Dependent Claim
45 words
Apparatus as defined in claim 1 including means coupled to said keys for producing discrete pulsed signals each having a frequency identifying an event in a dialogue, filter means for thereafter separating said discrete signals, and means connecting said filter means to said counting means.
