Abstract
Abstract In an x-ray cassette into which a flat light-emitting unit can be inserted through a slot to expose identifying markings on film, improved guiding means are provided for locating the marking unit correctly within the cassette. The guiding means include a track with an entry lip for directing the marking unit, a resilient pad supporting the track and being compressible until a stop on the track engages an inner surface of the cassette, and means in the slot which permit entry of the unit but prevent passage of light into the cassette.

Total Claims: 10
Claim 1
Independent Claim
152 words
In an x-ray cassette including a shallow body adapted to enclose film and a slot into which a flat flexible light-emitting unit can be inserted to expose identifying markings on the film; improved guiding means for locating the unit inside the cassette with respect to the film comprising a. a rigid track within the cassette against which the unit is slideable as it is inserted through the slot, i. said track facing the enclosed film and lying in a plane parallel thereto, and ii. said track including an entry lip at one end for directing the unit between the track and the film b. a resilient pad supporting the track within the cassette for resiliently urging the track against the unit to hold the latter flat against the enclosed film, and c. means located in the slot to permit entry of the unit but to prevent passage of light into the cassette.

Claim 3
Dependent Claim
14 words
The combination according to claim 1 wherein the track includes a central longitudinal indentation.
Claim 4
Dependent Claim
17 words
The combination according to claim 1 wherein the pad is formed with a central longitudinal cut-out portion.
Claim 5
Dependent Claim
40 words
The combination according to claim 1 wherein the cassette includes a lid hinged to one edge portion of the body, the slot being defined by the edge portion of the body and a cutout in the edge of the lid.
Claim 6
Dependent Claim
209 words
In an x-ray cassette including a shallow body adapted to enclose film and a slot into which a flat flexible light-emitting unit can be inserted to expose identifying markings on the film; improved guiding means for locating the unit inside the cassette with respect to the film comprising: a. a rigid track within the cassette against which the unit is slideable as it is inserted through the slot, i. said track facing the enclosed film and lying in a plane parallel thereto, ii. said track including an entry lip at one end for directing the unit between the track and the film, iii. a central longitudinal indentation, and iv. a stop projection at the end opposite the entry lip; b. a resilient pad supporting the track within the cassette for resiliently urging the track against the unit to hold the latter flat against the enclosed film independently of any pressure means for holding the film in place in the cassette, i. said pad being compressible until the stop projection engages an inner surface of the cassette, ii. said pad being formed with a central cutout portion; and c. a brush located in the slot to permit entry of the unit but to prevent passage of light into the cassette.
Claim 7
Dependent Claim
209 words
In an x-ray cassette including a shallow body adapted to enclose film and a slot into which a flat flexible light-emitting unit can be inserted to expose identifying markings on the film; improved guiding means for locating the unit inside the cassette with respect to the film comprising: a. a rigid track within the cassette against which the unit is slideable as it is inserted through the slot, i. said track facing the enclosed film and lying in a plane parallel thereto, ii. said track including an entry lip at one end for directing the unit between the track and the film, iii. a central longitudinal indentation, and iv. a stop projection at the end opposite the entry lip; b. a resilient pad supporting the track within the cassette for resiliently urging the track against the unit to hold the latter flat against the enclosed film independently of any pressure means for holding the film in place in the cassette, i. said pad being compressible until the stop projection engages an inner surface of the cassette, ii. said pad being formed with a central cutout portion; and c. a brush located in the slot to permit entry of the unit but to prevent passage of light into the cassette.
Claim 8
Dependent Claim
209 words
In an x-ray cassette including a shallow body adapted to enclose film, a lid hinged to one edge portion of the body and a slot in the cassette into which a flat flexible phosphorescent light-emitting unit can be inserted to expose identifying markings on the film; improved guiding means for locating the unit inside the cassette with respect to the film comprising a. a metal track within the cassette against which the unit slides as it is inserted through the slot, said track including i. an entry lip at one end which directs the unit between the track and the film, ii. a central longitudinal indentation, and iii. a stop projection at the end opposite the entry lip; b. a foam pad supporting the tract within the cassette and urging it resiliently toward the film, i. said pad being compressible until the stop projection engages an inner surface of the cassette, ii. said pad being formed with a central cut-out portion; and c. a brush located in the slot to permit entry of the unit while preventing passage of light into the cassette; d. said slot being defined between an edge portion of the body and part of that edge of the lid which is hinged to the body.
