Abstract
Abstract Apparatus for processing signals which are transmitted by the transducers of photoelectric cells scanning discrete marginal fields of square or rectangular film frames on a web of photographic film has relay-actuated switches which can connect the transducers of selected cells to each other and with the foreground and background inputs of a signal receiving circuit which is connected to the exposure controls of a copying machine or to a data carrier. The frames are examined by an attendant who energizes selected relays or several relays at a time to thereby cause the switches to transmit to the two inputs appropriate signals denoting the density and/or other characteristics of corresponding groups of neighboring marginal fields, depending upon whether the frame which is being inspected by attendant has been exposed in normal orientation, at right angles to normal orientation or upside down.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
Apparatus for processing signals which are produced subsequent to visual inspection of discrete portions of information on an elongated web-like carrier, particularly of the frames of an exposed and developed photographic film, at an inspecting station, comprising discrete scanning means for each of at least four marginal fields of a portion of information at said station, each of said scanning means including means for transmitting signals denoting a characteristic of the respective field of a portion of information at said station; and manually operable means for combining the signals transmitted by the signal transmitting means of different groups of scanning means based on visual determination of the orientation of information borne by the portion which is located at said station.
Claim 2
Dependent Claim
120 words
Apparatus for processing signals which are produced subsequent to visual inspection of discrete portions of information on an elongated web-like carrier, particularly of the frames of an exposed and developed photographic film, at an inspecting station, comprising discrete scanning means for each of at least four marginal fields of a portion of information at said station, each of said scanning means including means for transmitting signals denoting a characteristic of the respective field of a portion of information at said station; and manually operable means for combining the signals transmitted by the signal transmitting means of different groups of scanning means based on visual determination of the orientation of information borne by the portion which is located at said station.
Claim 3
Dependent Claim
32 words
Apparatus as defined in claim 1, further comprising signal receiving means having several inputs, said signal combining means including means for applying to said inputs signals from different groups of scanning means.
Claim 4
Dependent Claim
69 words
Apparatus as defined in claim 2, wherein each of said portions of information is a film frame and the information on at least the majority of said frames includes a foreground and a background each embracing at least two of said fields, one of said groups including the fields which are embraced by the foreground and another of said groups including the fields which are embraced by the background.
Claim 5
Dependent Claim
80 words
Apparatus as defined in claim 2, wherein said signal combining means comprises a discrete relay for each of said groups, switch means associated with each of said relays, one of said switch means being connected with said signal transmitting means and another of said switch means being connected with said one switch means and said inputs, and manually operable means for energizing said relays at the will of the person performing visual examination of portions of information at said station.
Claim 6
Dependent Claim
103 words
Apparatus as defined in claim 2, wherein each of said portions of information is of square or rectangular outline and said fields include a discrete field in the region of each corner of the respective portion of information, said signal combining means comprising a switch having terminals connected with the signal transmitting means of scanning means for each of said discrete fields and contact means movable between a plurality of positions in each of which the signal transmitting means of scanning means for a different pair of neighboring discrete fields are connected to each other, and means for moving said movable contact means.
Claim 7
Dependent Claim
54 words
Apparatus as defined in claim 5, further comprising second switch means connected between said first mentioned switch means and said inputs, and means for actuating said second switch means to thereby apply signals transmitted by signal transmitting means of scanning means for different pairs of neighboring fields to selected inputs of said receiving means.
Claim 8
Dependent Claim
39 words
Apparatus as defined in claim 6, wherein said moving means comprises a first relay and manually operated means for energizing said first relay, said actuating means including a second relay and manually operated means for energizing said second relay.
Claim 9
Dependent Claim
19 words
Apparatus as defined in claim 7, further comprising manually operated means for simultaneously energizing said first and second relays.
Claim 10
Dependent Claim
24 words
Apparatus as defined in claim 6, further comprising data carrier means connected with said receiving means and arranged to store signals in encoded form.
Claim 11
Dependent Claim
28 words
Apparatus as defined in claim 6, further comprising a copying machine for said portions of information, said machine including exposure control means connected with said signal receiving means.
