    Abstract: An audio-visual educational apparatus employing a disc record having audio messages recorded in spaced relationship and film strips mounted on an image carrier. The movement of a tone arm is synchronized with the position of the image carrier so that the images are positively correlated with the audio messages. A response mechanism for registering choices to the questions and/or instructions presented includes a series of pins which are adapted to be selectively inserted through holes or slots in coded sections on the control card to either hold or allow controlled advancement of the card relative to a display station.

    Abstract: A turntable drive release mechanism for an audiovisual educational apparatus of the type disclosed in U.S. Pat. No. 3,483,633 is disclosed employing a continuously driven friction drive wheel which is moved out of engagement with a turntable in response to an indexing lever carried on and moving with the turntable. The lever engages a releasable stop shaft and pivots to bear against a bellcrank which, through a link, moves the drive wheel away from the turntable while maintaining its contact with the drive motor. Upon release by the stop shaft the drive is returned to engagement by a spring and rotates the turntable one revolution until the indexing lever again contacts the bellcrank and stop shaft, thus returning the turntable to the ''''home'''' position.

    Abstract: A controlled, variable displacement, wobble plate compressor includes a pivotable wobble plate driven through an improved drive and support linkage including a universal joint and having its pivot point offset from the axis of the drive shaft so that at the ''''no stroke'''' position the pistons are all disposed at their top-dead-center positions. The capacity of the compressor is controlled by an improved system for varying the position of the wobble plate.

    Abstract: A device for releasably clamping an image support in an audiovisual educational apparatus to hold images carried by the support in a single common plane for visual presentation despite intermittent movement of the image support relative to the apparatus, thereby avoiding the necessity for frequent adjustment of the visual presentation for sharpness. The device is operable to release the image support to permit the intermittent relative movement to be effected freely and rapidly.
