Abstract
Abstract Each time the operator is projecting the start or end of what is to become an audio scene, he presses a store switch, commanding storage of the current frame count, thereby defining all the audio scenes on the film one after the other, for subsequent recording work. Thereafter, during recording work, the projector is referenced to the start and end frame counts of one scene at a time, one scene after another, as the operator controls semiautomatic recording work on successive scenes. A green, red and yellow indicator lamp are arranged in left-to-right order. When the film is ahead of the start of the referenced scene only the green lamp is bright, when past the end of the scene only the yellow, when in the middle of the scene only the red, when at the exact start of the scene both the green and red, when at the exact end of the scene both the red and the yellow.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
In a sound motion-picture film projector including a forwards-backwards frame counter operative for ascertaining frame count during both forwards and reverse transport operations and means activatable by the operator for commanding the automatic storage of frame counts which are to define the starts and ends of scenes to be worked on, an indicator arrangement for indicating position relative to stored frame counts, the indicator arrangement comprising two indicators, one operative for indicating that the frame count is lower than a predetermined stored frame count and the other operative for indicating that the frame count is higher than the predetermined stored frame count.
Claim 2
Dependent Claim
102 words
In a sound motion-picture film projector including a forwards-backwards frame counter operative for ascertaining frame count during both forwards and reverse transport operations and means activatable by the operator for commanding the automatic storage of frame counts which are to define the starts and ends of scenes to be worked on, an indicator arrangement for indicating position relative to stored frame counts, the indicator arrangement comprising two indicators, one operative for indicating that the frame count is lower than a predetermined stored frame count and the other operative for indicating that the frame count is higher than the predetermined stored frame count.
Claim 3
Dependent Claim
59 words
In a projector as defined in claim 1, said predetermined stored frame count being a first frame count, the indicator arrangement furthermore including a third indicator operative for indicating that the frame count is higher than a second predetermined stored frame count, the second stored frame count being the stored frame count next-higher than the first stored frame count.
Claim 4
Dependent Claim
28 words
In a projector as defined in claim 1, the two indicators being jointly operative for indicating that the frame count is equal to the predetermined stored frame count.
Claim 5
Dependent Claim
64 words
In a projector as defined in claim 2, the three indicators being a first, a second and a third indicator, the first and second indicators being jointly operative for indicating that the frame count is equal to the first stored frame count, the second and third indicators being jointly operative for indicating that the frame count is equal to the second stored frame count.
Claim 6
Dependent Claim
16 words
In a projector as defined in claim 1, the indicators being illuminatable indicators illuminated when operative.
Claim 7
Dependent Claim
51 words
In a projector as defined in claim 1, the two indicators being arranged on a horizontal line, the left one of the two indicators indicating frame counts lower than the predetermined stored frame count, the right one of the two indicators indicating frame counts higher than the predetermined stored frame count.
Claim 8
Dependent Claim
37 words
In a projector as defined in claim 4, the first, second and third indicators being arranged on a horizontal line, the first being at the left, the third at the right and the second in the middle.
Claim 9
Dependent Claim
26 words
In a projector as defined in claim 1, the two indicators being distinguishable from each other with respect to the color of the indications they provide.
Claim 10
Dependent Claim
26 words
In a projector as defined in claim 4, the three indicators being distinguishable from one another with respect to the color of the indications they provide.
