Abstract
Abstract For use on an overhead projector to give an illusion of motion, a transparency sheet bearing art work in the form of a grid is superposed on a relatively movable transparency sheet or web bearing a second or control grid. The lines or groups of lines of the art work grid and the second grid are parallel and both are at an angle to the direction of relative motion. On either sheet the lines may be of any appropriate color and may be made up of rows of dots. Dots of differing color in rows at different angles may be used. On either sheet, but not both, the lines are desirably arcuate and drawn on like radii about centers successively offset on a line parallel to the direction of relative movement, such arcuate lines being tangent to a construction line at the desired 45* angle to the direction of motion. On both sheets, the width or apparent width of respective lines is substantially identical with the width or apparent width of intervening spaces between the lines.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
76 words
A combination of relatively movable transparencies for use in a projection system to give the projected image an illusion of motion, each of the said transparencies comprising a grid, one of said grids comprising an art grid and the other a control grid, and means for guiding one of said transparencies for movement in a predetermined direction with respect to the other, both grids having lines at an acute angle to the direction of relative motion.
Claim 2
Dependent Claim
76 words
A combination of relatively movable transparencies for use in a projection system to give the projected image an illusion of motion, each of the said transparencies comprising a grid, one of said grids comprising an art grid and the other a control grid, and means for guiding one of said transparencies for movement in a predetermined direction with respect to the other, both grids having lines at an acute angle to the direction of relative motion.
Claim 3
Dependent Claim
31 words
A combination according to claim 1 in which each grid comprises lines and intervening spaces, the width of the respective lines and the respective spaces being substantially uniform in both grids.
Claim 4
Dependent Claim
35 words
A combination according to claim 1 in which the lines of one of said grids are arcuate and the lines of the other of said grids are at an angle approximating 45* to said direction.
Claim 5
Dependent Claim
34 words
A combination according to claim 3 in which said arcuate lines are respectively tangent to lines which are angularly related to the direction of relative movement between the control grid and the art grid.
Claim 6
Dependent Claim
32 words
A combination according to claim 4 in which the lines of one of said grids are arcuate and substantially centered on tangential construction lines at approximately 45* to direction of relative motion.
Claim 7
Dependent Claim
145 words
A combination of relatively movable transparencies for use in a projection system to give the projected image an illusion of motion, each of the said transparencies comprising a grid, one of said grids comprising an art grid and the other a control grid, and means for guiding one of said transparencies for movement in a predetermined direction with respect to the other, both grids having lines at an acute angle to the direction of relative motion, said lines of at least one of said grids comprising rows of dots with intervening background color contrasting with said dots, one grid comprising rows of dots of one color, said rows being at a predetermined angle with respect to direction of relative movement between said grids, and means providing second rows of dots of different color and drawn at an angle to the first mentioned rows of dots.
Claim 8
Dependent Claim
145 words
A combination of relatively movable transparencies for use in a projection system to give the projected image an illusion of motion, each of the said transparencies comprising a grid, one of said grids comprising an art grid and the other a control grid, and means for guiding one of said transparencies for movement in a predetermined direction with respect to the other, both grids having lines at an acute angle to the direction of relative motion, said lines of at least one of said grids comprising rows of dots with intervening background color contrasting with said dots, one grid comprising rows of dots of one color, said rows being at a predetermined angle with respect to direction of relative movement between said grids, and means providing second rows of dots of different color and drawn at an angle to the first mentioned rows of dots.
Claim 9
Dependent Claim
83 words
The combination with a book of transparencies comprising leaves bearing art work for projection, the art work being comprised of groups of grid lines which are substantially parallel, the grid lines of each group being slightly offset laterally with respect to the grid lines of an adjacent group, and a control grid having a set of lines at the same angle as the grid lines on said leaves, the control grid being mounted for movement with respect to successive leaves respectively associated therewith.
Claim 10
Dependent Claim
83 words
The combination with a book of transparencies comprising leaves bearing art work for projection, the art work being comprised of groups of grid lines which are substantially parallel, the grid lines of each group being slightly offset laterally with respect to the grid lines of an adjacent group, and a control grid having a set of lines at the same angle as the grid lines on said leaves, the control grid being mounted for movement with respect to successive leaves respectively associated therewith.
Claim 11
Dependent Claim
17 words
A combination according to claim 7 in which the lines of one of said grids are arcuate.
Claim 12
Dependent Claim
28 words
A combination according to claim 7 in which the control grid comprises a web having means guiding it for movement beneath any leaf of said book superimposed thereon.
Claim 13
Dependent Claim
40 words
A combination according to claim 9 in further combination with means for slowly advancing the control grid web, said means being impositive in its action on said web whereby said web may be manually retracted from any position of advance.
Claim 14
Dependent Claim
126 words
A projector comprising in combination a stage, a projection lens, a light source, a transparency having means mounting it for movement in a predetermined direction across the stage and provided with groups of lines constituting a control grid, the lines of each group being disposed at an acute angle to said direction, a second transparency in superimposed relation to the first transparency and having a releasable means for holding it fixed with respect to the stage and provided with an art grid comprising groups of lines substantially parallel to each other and also at an acute angle to the said direction of movement of the first transparency respecting the stage, the lines of respective groups being of uniform width substantially identical to the spacing between lines.
Claim 15
Dependent Claim
126 words
A projector comprising in combination a stage, a projection lens, a light source, a transparency having means mounting it for movement in a predetermined direction across the stage and provided with groups of lines constituting a control grid, the lines of each group being disposed at an acute angle to said direction, a second transparency in superimposed relation to the first transparency and having a releasable means for holding it fixed with respect to the stage and provided with an art grid comprising groups of lines substantially parallel to each other and also at an acute angle to the said direction of movement of the first transparency respecting the stage, the lines of respective groups being of uniform width substantially identical to the spacing between lines.
Claim 16
Dependent Claim
51 words
A projector according to claim 11 in which the second transparency comprises a leaf of a book in which other like transparencies are bound and which are selectively movable to and from operative positions on said stage for coaction with the first mentioned transparency on which the control grid is provided.
