Abstract: A tube assembly for medicament and the like wherein the contents can be discharged by squeezing the tube. The tube assembly includes a nozzle having a discharge port and an axial central bore with a diaphragm extending across the bore at the inner end of the discharge port. A piercer unit mounted in the nozzle portion is mounted for axial movement in the central bore from a first readily position, axially inwardly of the thin wall, to a second discharge position puncturing the diaphragm. The assembly further includes a cap having a support plug sized in the discharge port for abutment against the diaphragm and to prevent inadvertent puncture thereof. The piercer unit includes a hollow needlelike member adapted for movement axially in the central bore and a piston for mounting the hollow needlelike member slidably in the nozzle portion for actuating the needlelike member from the first position to the second position upon application of external pressure, such as squeezing pressure applied to the tube.

Abstract: An automatic focusing mechanism for adjusting the focus setting of the objective lens of an optical instrument such as a photographic camera. The adjustable focusing cell of the objective lens is coupled to a pivotal reception means so that the focus setting of the objective lens is maintained coincident with the distance between the camera and an object to be photographed when the longitudinal axis of the reception means is in alignment with a reflected light beam image transmitted from the camera to the object from an emission means spaced from the reception means. A rangefinder circuit controls the pivotal motion of the reception means so as to maintain its longitudinal axis in alignment with the reflected light beam image through variations in camera-to-object distance.

Abstract: A photographic apparatus having a lens movable along an axis for automatically focusing an object to be photographed is disclosed. The apparatus includes a rotatable sleeve controlled by electrical signals produced by photoreceptor means adapted to receive light emitted by the apparatus and reflected from the object. The sleeve effectuates the movement of the lens along an axis to bring the object into focus. The apparatus further includes assembly means, carrying the photoreceptor means, pivotably secured to the sleeve for adjusting the light received by the photoreceptor means by an amount corresponding to the rotation of the sleeve, thereby changing the electrical signals to maintain the object in focus.
