Abstract

Abstract A film cassette includes a rigid base having a cylindrical film supporting surface and a resiliently curved cover which closes over the cylindrical surface in mating relationship therewith to enclose the film and define flat, rectangular external cassette surfaces. The cassette is provided with an exposure window through which the film can be exposed to patient identification information by photographic projection and a color-coded indicator to give a visual signal when the film has been patient identified. An observation opening may also be provided for positive inspection to ensure the presence of film in the cassette.

Dependent Claim 16 words
its first position when the cassette is loaded with film which has not been identified, and
Claim 3
Dependent Claim 5 words
first and second extending legs,
Claim 4
Dependent Claim 5 words
first and second extending legs,
Claim 5
Dependent Claim 14 words
a window defined by and passing through one of said base and cover, and
Claim 6
Dependent Claim 14 words
a window defined by and passing through one of said base and cover, and
Claim 7
Dependent Claim 88 words
A light opaque and X-ray transparent film cassette adapted to receive a sheet of X-ray film which may be exposed with identification data, said cassette comprising: a. a base having a recess for receiving said sheet of X-ray film; b. a cover adapted to close upon and cooperate with said base for holding said X-ray film in the recess; c. means for enabling a portion of said sheet of X-ray film to be exposed with said identification data for identifying said X-ray film, said exposure enabling means including
Claim 8
Dependent Claim 88 words
A light opaque and X-ray transparent film cassette adapted to receive a sheet of X-ray film which may be exposed with identification data, said cassette comprising: a. a base having a recess for receiving said sheet of X-ray film; b. a cover adapted to close upon and cooperate with said base for holding said X-ray film in the recess; c. means for enabling a portion of said sheet of X-ray film to be exposed with said identification data for identifying said X-ray film, said exposure enabling means including
Claim 9
Dependent Claim 212 words
A light opaque and X-ray transparent film cassette adapted to receive a sheet of X-ray film which may be exposed with identification data, said cassette comprising: a. a base having a recess for receiving said sheet of X-ray film; b. a cover adapted to close upon and cooperate with said base for holding said X-ray film in the recess; c. means for enabling a portion of said sheet of X-ray film to be exposed with said identification data for identifying said X-ray film, said exposure enabling means including 1. a window defined by and passing through one of said base and cover, and 2. means for selectively preventing light from passing through said window; d. an indicator within said cassette and at least partially visible from outside said cassette when said cover is closed upon said base, said indicator being movable to a first position when said sheet of film is received in said recess and to a second position when said sheet of film is so identified, whereby the operator can readily determine whether said sheet of film has been identified by visually checking the position of said indicator; and e. window means adjacent said indicator whereby the position of the indicator may be checked by viewing through said window means.
Claim 10
Dependent Claim 212 words
A light opaque and X-ray transparent film cassette adapted to receive a sheet of X-ray film which may be exposed with identification data, said cassette comprising: a. a base having a recess for receiving said sheet of X-ray film; b. a cover adapted to close upon and cooperate with said base for holding said X-ray film in the recess; c. means for enabling a portion of said sheet of X-ray film to be exposed with said identification data for identifying said X-ray film, said exposure enabling means including 1. a window defined by and passing through one of said base and cover, and 2. means for selectively preventing light from passing through said window; d. an indicator within said cassette and at least partially visible from outside said cassette when said cover is closed upon said base, said indicator being movable to a first position when said sheet of film is received in said recess and to a second position when said sheet of film is so identified, whereby the operator can readily determine whether said sheet of film has been identified by visually checking the position of said indicator; and e. window means adjacent said indicator whereby the position of the indicator may be checked by viewing through said window means.
Claim 11
Dependent Claim 18 words
A film cassette as defined in claim 1 wherein: a. said indicator comprises a pivotally mounted toggle having
Claim 12
Dependent Claim 108 words
means for selectively preventing light from passing through said window; d. an indicator within said cassette and at least partially visible from outside said cassette when said cover is closed upon said base, said indicator being movable to a first position when said sheet of film is received in said recess and to a second position when said sheet of film is so identified, whereby the operator can readily determine whether said sheet of film has been identified by visually checking the position of said indicator; and e. window means adjacent said indicator whereby the position of the indicator may be checked by viewing through said window means.
Claim 13
Dependent Claim 108 words
means for selectively preventing light from passing through said window; d. an indicator within said cassette and at least partially visible from outside said cassette when said cover is closed upon said base, said indicator being movable to a first position when said sheet of film is received in said recess and to a second position when said sheet of film is so identified, whereby the operator can readily determine whether said sheet of film has been identified by visually checking the position of said indicator; and e. window means adjacent said indicator whereby the position of the indicator may be checked by viewing through said window means.
Claim 14
Dependent Claim 8 words
its second position when said film is identified.
Claim 15
Dependent Claim 8 words
its second position when said film is identified.
Claim 16
Dependent Claim 21 words
a first position in which said first leg closely underlies and said second leg is spaced from said window means, and
Claim 17
Dependent Claim 21 words
a first position in which said first leg closely underlies and said second leg is spaced from said window means, and
Claim 18
Dependent Claim 40 words
A film cassette as defined in claim 2 wherein said first and second extending legs are different colors whereby the operator can visually determine whether the film has been patient identified by observing the color appearing in said window means.
Claim 19
Dependent Claim 27 words
a second position in which said first leg is spaced from and said second leg closely underlies said window means; and b. said toggle is rotated to
