US Patent:

39596575, May 25, 1976

Filed:

Apr 7, 1975

Appl. No.:

5/565583

Inventors:

Seymour Katz - Glen Cove NY
Victor R. Brown - West Hempstead NY

Assignee:

IPCO Hospital Supply Corporation - White Plains NY

International Classification:

G03B 4116

US Classification:

250476

Abstract:

Apparatus for placing identifying indicia on x-ray film within a cassette, in which an electroluminescent panel is provided with a resiliently biased slide element movably mounted on a cassette supporting member. As the cassette is positioned on the supporting member, a portion of the panel protrudes into a slot-shaped opening in one edge of the cassette, and the cassette edge simultaneously urges the slide element away from the protruding portion such that only the protruding portion and an indicia bearing card extend into the opening. When the cassette reaches its proper position on the support member, an electrical circuit automatically closes for a predetermined period of time to illuminate the panel and thereby expose the film with the information on the card.

International Classification:

G03B 4116

US Classification:

250476

Abstract:

Apparatus for exposing film, such as X-ray film, in a cassette with light of predetermined intensity from a light density scale, and a method of using such apparatus and the developed film. The apparatus is provided with an energizable luminescent element which cooperates with an indicia bearing member provided with predetermined indicia and adapted to be inserted into imaging relation with respect to the luminescent element. A light density scale preferably formed of plural areas or strips of different densities is provided either on the luminescent element or on the indicia bearing member. When for example an X-ray film cassette is properly loaded onto the apparatus, the luminescent element is energized so as to expose the X-ray film simultaneously to the predetermined indicia and to light of different predetermined intensities as transmitted through the light density scale. Prior to or subsequent to this light imaging operation, the X-ray film in the cassette is exposed to an X-ray image of a subject. Then, the exposed X-ray film is developed to form a viewable image of the subject, the predetermined indicia and the light density scale.

Abstract:

Apparatus for placing identifying indicia on x-ray film within a cassette, in which an electroluminescent panel is provided with a resiliently biased slide element movably mounted on a cassette supporting member. A printing unit applies time and data information to an indicia bearing card and simultaneously activates a control circuit for a predetermined time interval to condition the circuit for the energization of the panel only during this interval. The thus imprinted card is then placed on the panel, and as the cassette is positioned on the supporting member a portion of the panel protrudes into a slot-shaped opening in one edge of the cassette. When the cassette reaches its proper position on the support member, the control circuit is effective to illuminate the panel and thereby expose the film with the information on the card.
