Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
A device for creating a continuously moving and changing visual image comprising a support having a wall comprised of a translucent screen, a stationary light source on said support, a plurality of reflectors arranged on said support in laterally spaced relation to reflect light from the source onto the screen, said reflectors each comprising a disc having thereon a reflective surface comprised of deformed metallized plastic material of different colors and having randomly oriented reflective surfaces, the light source being positioned generally intermediate the reflectors and having means to direct cones of light in different directions upon each reflector, and being out of the optical path from the reflectors to the screen, and means for rotating said reflectors.
Claim 2
Independent Claim
118 words
A device for creating a continuously moving and changing visual image comprising a support having a wall comprised of a translucent screen, a stationary light source on said support, a plurality of reflectors arranged on said support in laterally spaced relation to reflect light from the source onto the screen, said reflectors each comprising a disc having thereon a reflective surface comprised of deformed metallized plastic material of different colors and having randomly oriented reflective surfaces, the light source being positioned generally intermediate the reflectors and having means to direct cones of light in different directions upon each reflector, and being out of the optical path from the reflectors to the screen, and means for rotating said reflectors.
Claim 3
Dependent Claim
25 words
The combination claimed in claim 1, said reflectors light source and screen being arranged so that the reflections at least partly overlap on the screen.
Claim 4
Independent Claim
75 words
A device for projecting a continuously moving and changing visual image onto a screen comprising, a stationary light source, a reflector arranged to reflect light from the source onto the screen, said reflector comprising an inflatable support having thereon randomly oriented refLecting deformable metallized plastic material, means for rotating said support, and means for varying the degree of inflation of said support whereby to cause variations in the area and deformity of the reflecting material.
Claim 5
Independent Claim
75 words
A device for projecting a continuously moving and changing visual image onto a screen comprising, a stationary light source, a reflector arranged to reflect light from the source onto the screen, said reflector comprising an inflatable support having thereon randomly oriented refLecting deformable metallized plastic material, means for rotating said support, and means for varying the degree of inflation of said support whereby to cause variations in the area and deformity of the reflecting material.
