Abstract: A hand-held portable diagnostic assay system for conducting and recording luminescent reactions for generating and recording luminescent read-out signals generated by a testing assembly and recordable on an image recording medium. A carrier assembly receives the testing assembly and is operable between first and second conditions. An assembly prevents unintended insertion of the testing assembly into the carrier assembly when in the first condition, and a mechanism prevents unintended removal of the testing assembly from the carrier assembly when in the second condition.

Abstract: A self developing photographic apparatus comprising: a housing including a film exit slot; exposure means operable for effecting an exposure; a film assemblage of the self-developing type including at least one exposable area and a rupturable reservoir containing processing fluid being associated with a corresponding exposable area. The apparatus also includes pressure applying means operable for rupturing the reservoir to thereby dispense and spread the fluid over the exposable area so as to initiate development of latent images as the film is withdrawn from the housing. Also included is at least one film engaging assembly coupled to the housing and located exteriorly of the film exit slot. In another embodiment, the invention includes a method of processing a film assemblage such that the film spreading fluid is applied substantially uniform.

Abstract: The present disclosure relates to several embodiments in which different self-developing film formats are constructed in order to permit easy operator separation of the pod and trap from adjacent integral film units.
