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.

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.

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.
