Abstract
Abstract An apparatus for processing film that injects fluid into a selfsealing package containing a photosensitive film, measures the distension of the package, terminates the flow of fluid into the package when the package has reached a predetermined size and agitates the package to cause the injected fluid to flow uniformly upon the film emulsion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
An apparatus for processing a photosensitive film contained in a hermetically sealed packet comprising: a pair of jaws for engaging opposite sides of such packet to locate said packet in a predetermined position for injecting processing fluid therein; means operatively associated with said pair of jaws for generating a signal upon detecting the presence of a packet in said position; piercing means including a hollow tubular member for piercing the packet and for conducting such fluid into the packet; control means responsive to said signal from said generating means for initiating the flow of such fluid through said piercing means; means engageable with said packet for producing a signal upon sensing a predetermined distension of the packet; terminating means responsive to said signal from said producing means for terminating the flow of such fluid into the packet; whereby a designated amount of such fluid is injected into said packet for processing the film contained therein.
Claim 2
Independent Claim
155 words
An apparatus for processing a photosensitive film contained in a hermetically sealed packet comprising: a pair of jaws for engaging opposite sides of such packet to locate said packet in a predetermined position for injecting processing fluid therein; means operatively associated with said pair of jaws for generating a signal upon detecting the presence of a packet in said position; piercing means including a hollow tubular member for piercing the packet and for conducting such fluid into the packet; control means responsive to said signal from said generating means for initiating the flow of such fluid through said piercing means; means engageable with said packet for producing a signal upon sensing a predetermined distension of the packet; terminating means responsive to said signal from said producing means for terminating the flow of such fluid into the packet; whereby a designated amount of such fluid is injected into said packet for processing the film contained therein.
Claim 3
Dependent Claim
33 words
The invention according to claim 1 and further comprising an alarm responsive to said signal from said producing means for indicating that the desired volume of fluid has been injected into the packet.
Claim 4
Dependent Claim
68 words
The invention according to claim 1 further including means for agitating the fluid injected into the packet to facilitate complete distribution of said fluid on said film comprising: means for holding said packet on opposite ends during agitation; and means associated with said packet holding means for alternately pressing opposite ends of the packet to cause the fluid contained therein to move back and forth on the film.
Claim 5
Dependent Claim
21 words
The invention according to claim 3 wherein said agitating means is actuated in response to said signal from said producing means.
Claim 6
Dependent Claim
85 words
The invention according to claim 3 wherein said holding means comprises: packet engaging pads mounted at opposite ends of a rectangular frame for contacting the opposite ends of the packet; wall means spaced from the frame mounted pads for receiving a packet therebetween; and means pivotally mounting said frame for oscillatory movement about an axis intermediate the pads such that when a packet is placed between the packet engaging pads and said wall means, said packet is alternately pressed at opposite ends by the pads.
