Abstract
Abstract A visual education system for making and viewing a multi-image film strip. The system includes a camera movable lengthwise and widthwise by a programming apparatus to expose on a film strip a plurality of discrete images; a viewing apparatus for projecting the discrete images on the film strip onto a viewing screen and a slide mount having adjacent rows of apertures therein for receiving the multi-image film strip. The slide mount includes a guide channel that cooperates with an aperture member of the viewing apparatus for projecting the discrete images on the film strip onto the viewing screen.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
A multi-image slide mount comprising a plate-like body having at least two adjacent rows of opposed apertures therein; said plate-like body being adopted to receive and secure a film strip having images thereon in alignment with said apertures; guide means on a face of said body extending sequentially about said apertures for providing a guide channel, said guide means comprising a raised elongated guide rib adjacent each side of said rows of apertures and a raised transverse rib adjacent each end of said rows of apertures; said elongated ribs alternately extending transversely from one of said transverse ribs and the other of said transverse ribs and terminating in a free end at a point spaced from one or the other of said transverse ribs to provide said guide channel between said ribs and between opposed apertures at one end of said adjacent rows of apertures.
Claim 2
Dependent Claim
145 words
A multi-image slide mount comprising a plate-like body having at least two adjacent rows of opposed apertures therein; said plate-like body being adopted to receive and secure a film strip having images thereon in alignment with said apertures; guide means on a face of said body extending sequentially about said apertures for providing a guide channel, said guide means comprising a raised elongated guide rib adjacent each side of said rows of apertures and a raised transverse rib adjacent each end of said rows of apertures; said elongated ribs alternately extending transversely from one of said transverse ribs and the other of said transverse ribs and terminating in a free end at a point spaced from one or the other of said transverse ribs to provide said guide channel between said ribs and between opposed apertures at one end of said adjacent rows of apertures.
Claim 3
Dependent Claim
33 words
A multi-image slide mount as claimed in claim 1, wherein the spacing between said elongated guide ribs and between said free ends of said elongated ribs and said transverse ribs is substantially equal.
Claim 4
Dependent Claim
42 words
A multi-image slide mount as claimed in claim 1, wherein said plate-like body is formed of two juxtaposed plate-like members each having a plurality of corresponding apertures therein, and including interlocking means in each said plate-like members for locking said members together.
Claim 5
Dependent Claim
27 words
A multi-image slide mount as claimed in claim 3, wherein one of said plate-like members is provided with a rectangular depression for receiving a film strip therein.
Claim 6
Dependent Claim
46 words
A multi-image slide mount as claimed in claim 1, wherein said plate-like body is substantially rectangular and said rows of apertures extend transversely to the longitudinal axis of said body and include an elongated ridge on each side of said body parallel to said longitudinal axis.
Claim 7
Dependent Claim
31 words
A multi-image slide mount as claimed in claim 1, wherein there is further provided at least one aligning groove in a face of said body for guiding of said slide mount.
