An auto-changer for optical discs. At least one carousel rotatable about a horizontal axis stores a large number of discs. A picker moves into the carousel to grasp a disc in a horizontal position in the carousel and then move the disc to a position outside of the carousel. A transfer arm grabs the disc from the picker and swings the disc in an arcuate path over to a disc player, where it is deposited for playing.

Biological reaction cell

Method and apparatus for use in the diagnostic analysis of a liquid specimen through binding assays. The apparatus includes a rigid body having an elongated, shallow well formed in it, with a plurality of elongated strips, preferably in the form of cotton threads, stretched across the well in spaced relationship and generally perpendicular to the well's longitudinal axis. Each thread is coated with a separate binding conjugate such as an antigen or allergen. A cover plate that includes a thin plastic layer and an overlaying thin metallic layer covers the well to form an enclosed chamber having a specific volume. The metallic layer includes a separate elongated aperture in alignment with each coated thread. A liquid specimen is introduced into the chamber through one of two ports, for incubation with the coated threads, after which the specimen is removed and the reaction that occurred on each thread is determined.

Binding assay system and method of making and using same

A portable photo chamber for photographically recording the extent of a chemical reaction such as in an immunological test, wherein a substrate emitting radiation such as gamma radiation is supported in facing contact with a film and with intensifying means, so that exposure time is reduced as a result of emission of further radiation such as a visible light from the intensifying means and its recording on the film. The photo chamber includes retaining means for supporting the substrate, which itself is preferably enclosed in a container such as a pipette, and translating means for moving the substrate into closely facing relationship to the film and also to a spaced-apart position within the chamber. In a preferred embodiment, the photo chamber utilizes an instant photographic system with film processing means attached to the chamber, so that the photo chamber is both portable and self-contained for use in remote locations.
