Abstract: 1,162,234. Camera shutter actuating mechanism. EASTMAN KODAK CO. Nov.3, 1966 [Nov.5, 1965], No.49318/66. Heading G2A. A photographic camera having an automatic film advancement mechanism comprises a movable element associated with film in the camera for the positioning thereof, and a release, mounted on the camera body, having a first means thereon for preventing the movement of a shutter actuating mechanism when the release is in its first position and to permit the shutter actuating mechanism to move, under a biasing means, to the shutter actuating position when the release is in its second position, and said release having a second means to prevent movement of the movable element when the release is in its second position, there being a further means to return the shutter actuating means to its initial position when the release returns to its first position. As shown, on depression of the release 1, a drive gear 5, slidably mounted on a keyway on shaft 3 connected to the film take-up spool, is depressed against the bias of a spring 6. An abutment 16 on the release 1 is simultaneously moved into the path of a ratchet 7 rigidly mounted on the shaft 3, thereby stopping its rotation under a motor bias now activated. An abutment 17 on the release 1 now releases a shutter actuating lever 13, which turns under a spring bias 14, and carries levers 11 and 12 and a gear segment 10 with it. As the shutter is actuated by lever 13, the levers 11 and 12 are advanced a little were by a toggle spring 18 mounted on the gear segment 10 which comes to rest above the drive gear 5. On allowing the release 1 to return, the drive gear 5. engages with the segment 10, the ratchet 7 is released and the drive gear 5 rotates, turning the segment 10 also. The levers 11 and 12 turn with the segment 10 until an abutment 19 on the lever 12 contacts the lever 13 which then turns with the levers 11 and 12. At the end of the stroke, the lever 13 slides over the abutment 15, and the lever 12 follows it but is lifted on to the top thereof by means of an extension on it sliding on the abutment 15.

Title: Cuvettes
IPC: B01L3/00
Filed: 1976-12-17
Abstract: A multichamber cuvette for maintaining in independent and separate condition at least two reactants, one of which may be a sample, until such time that it is desired to mix them for reaction with each other for photometric analysis in the cuvette. At least one of the chambers has a pair of optical quality windows aligned with one another for analysis of the then liquid contents extending between the windows. The cuvette body is of upright construction, defining at least two such chambers laterally of one another, open at the top for filling separately or simultaneously, and interconnected adjacent their lower extremities by a passageway of inverted U shape. The passageway is of an effective height exceeding the highest filling level of each chamber by a distance at least as great as any capillary rise in the passageway beyond such level of the particular liquid in that chamber. Accidental mixing of the chamber contents is prevented by entrapment of air in the passageway by the respective liquids in the chambers and partially filling the legs of the passageway. Mixing through the passageway is effected by the forced flow of fluids therethrough from one chamber to the other while one of the chambers is vented to the atmosphere at the top. The passageway is so configured and also dimensioned in cross section as to allow for the free flow of liquid between the chambers.
