Claim 3

Means to reproduce and project audiovisual information according to claim 1, wherein said rail means is a hollow member in fluid communication with hydraulic pump means.

Claim 4

Means to reproduce and project audiovisual information according to claim 1, wherein said moving means include hydraulic means actuating a flexible member cooperable with said rail means.

Claim 5

Means to reproduce and project audiovisual information according to claim 1, wherein said moving means include a flexible member forming an endless loop following said rail means and also winding itself around a wheel.

Claim 6

Means to reproduce and project audiovisual information according to claim 1, wherein said rail means is a hollow depression formed in a plate member.

Claim 7

Means to simultaneously reproduce and project audiovisual information comprising: a. support means for fixedly holding an audiovisual record having a projectable image and an information track, b. optical projection means directed onto said image, c. an annular member rotatably mounted adjacent said support means for rotation about its center of rotation, d. a transducer secured to said annular member and cooperable with said track, e. a flexible member wrapped about a circular path on said annular member, one end of said flexible member secured to spring means, the other end of said flexible member being secured to moving means, said moving means moving said flexible member against the force of said spring means thereby smoothly rotating said annular member and carrying said transducer progressively along and in an information-scanning relation to said track.

Claim 8

Means to simultaneously reproduce and project audiovisual information comprising: a. support means for fixedly holding an audiovisual record having a projectable image and an information track, b. optical projection means directed onto said image, c. an annular member rotatably mounted adjacent said support means for rotation about its center of rotation, d. a transducer secured to said annular member and cooperable with said track, e. a flexible member wrapped about a circular path on said annular member, one end of said flexible member secured to spring means, the other end of said flexible member being secured to moving means, said moving means moving said flexible member against the force of said spring means thereby smoothly rotating said annular member and carrying said transducer progressively along and in an information-scanning relation to said track.

Claim 9

In combination, an audiovisual apparatus accepting an audiovisual slide-mount; said slide-mount comprising a base member having on one side a hole coaxially surrounded by an information track, a light-reflecting layer on the other side, and a frame member framing and holding a projectable transparency in an overlaying relation to said layer; said apparatus having: a. seat means for fixedly holding said slide-mount, b. a rotating transducer scanning said information track, c. shaft means supporting said transducer for rotation, said shaft means entering and engaging said hole thus aligning said rotating transducer with said track, d. a radiation beam passing through said transparency and reflected by said layer back through said transparency to retrieve the imaging information contained therein.

Claim 10

In combination, an audiovisual apparatus accepting an audiovisual slide-mount; said slide-mount comprising a base member having on one side a hole coaxially surrounded by an information track, a light-reflecting layer on the other side, and a frame member framing and holding a projectable transparency in an overlaying relation to said layer; said apparatus having: a. seat means for fixedly holding said slide-mount, b. a rotating transducer scanning said information track, c. shaft means supporting said transducer for rotation, said shaft means entering and engaging said hole thus aligning said rotating transducer with said track, d. a radiation beam passing through said transparency and reflected by said layer back through said transparency to retrieve the imaging information contained therein.

Claim 11

In an audiovisual apparatus accepting for reproduction an audiovisual record having an image and an information track: a. support means for fixedly holding said record, b. hollow tube means having a fluid therein, c. plunger means moving in said tube means in piston-like fashion, d. a carriage slidably disposed on said tube means and magnetically coupled to said plunger means, e. a transducer mounted on said carriage, said transducer being cooperable with said track, f. fluid-moving means connected to said tube means to move said fluid in said tube means and thereby said plunger means and thereby said carriage, and thus carry said transDucer progressively along and in an information scanning relation to said track.

Claim 12

In an audiovisual apparatus accepting for reproduction an audiovisual record having an image and an information track: a. support means for fixedly holding said record, b. hollow tube means having a fluid therein, c. plunger means moving in said tube means in piston-like fashion, d. a carriage slidably disposed on said tube means and magnetically coupled to said plunger means, e. a transducer mounted on said carriage, said transducer being cooperable with said track, f. fluid-moving means connected to said tube means to move said fluid in said tube means and thereby said plunger means and thereby said carriage, and thus carry said transDucer progressively along and in an information scanning relation to said track.

Claim 13
