Abstract
Abstract A device for animating a picture painted on a transparency. A light-intercepting sheet having a pattern of embossed motion lines overlies portions of the picture to be animated an the two are sandwiched between rotary and stationary polarized sheets. The picture becomes animated when the rotary polarizer is rotated and light is transmitted through the sheets in a manner to illuminate the picture.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
A light-intercepting sheet for animating selected portions of a picture designed to overlie the light-intercepting sheet, comprising a sheet of light transmitting material having lightintercepting patterns of closely spaced generally parallel motion lines embossed in areas on one face thereof for producing traveling shadows on said selected portions of the picture in cooperation with a stationary and a rotary polarizer, other areas of said one face which would produce a blinking effect when the light-intercepting sheet is positioned between said stationary and rotary polarizers and light passed through said areas being embossed with a no-motion pattern to minimize said blinking effect.
Claim 2
Dependent Claim
101 words
A light-intercepting sheet for animating selected portions of a picture designed to overlie the light-intercepting sheet, comprising a sheet of light transmitting material having lightintercepting patterns of closely spaced generally parallel motion lines embossed in areas on one face thereof for producing traveling shadows on said selected portions of the picture in cooperation with a stationary and a rotary polarizer, other areas of said one face which would produce a blinking effect when the light-intercepting sheet is positioned between said stationary and rotary polarizers and light passed through said areas being embossed with a no-motion pattern to minimize said blinking effect.
Claim 3
Dependent Claim
26 words
The invention as defined in claim 1 wherein said sheet is made of isotropic material and the embossed areas impart a birefringentlike character to said sheet.
Claim 4
Dependent Claim
19 words
The invention as defined in claim 2 wherein said sheet is a thin sheet of optically inactive plastic material.
Claim 5
Dependent Claim
24 words
The invention as defined in claim 3 wherein said no-motion pattern comprises a plurality of small closely spaced dotlike indentations in said one face.
Claim 6
Dependent Claim
17 words
The invention as defined in claim 4 wherein the thickness of said sheet is about 0.01 inches.
Claim 7
Dependent Claim
21 words
The invention as defined in claim 4 wherein the density of the indentations is about 900 or more per square inch.
Claim 8
Dependent Claim
36 words
The invention as defined in claim 6 wherein the area per square inch covered by said indentations is substantially equal to or less than the area per square inch covered by the spaces between the indentations.
Claim 9
Dependent Claim
45 words
The invention as defined in claim 1 including a light-transmitting picture overlying the other face of said sheet, portions of said picture to be animated overlying said patterns of motion lines, portions of said picture which are not to be animated overlying said no-motion pattern.
Claim 10
Dependent Claim
26 words
The invention as defined in claim 8 wherein said picture is formed on a separate light-transmitting sheet, bonded to said other face of said light-intercepting sheet.
Claim 11
Dependent Claim
79 words
The invention as defined in claim 8 including a stationary polarized sheet, a rotary polarized sheet, means for rotating the rotary polarized sheet, and means for supporting said sheets in a manner to enable light to be transmitted through one of said polarized sheets and then through said light-intercepting sheet and then through the other of said polarized sheets whereby said picture can be illuminated with said selected portions thereof animated when viewed through one of said polarized sheets.
