  • Patent number: 4515434
    Abstract: A fiber optic connector is disclosed for optically coupling a pair of fiber optic cables or a single fiber optic cable and a light source or detector. A terminal member includes a pair of identical matching halves defining a through hole extending axially therethrough. The through hole has a first portion extending through a mating end of the terminal member and sized to snugly receive a length of the fiber core stripped of the outer coating and properly positioning the core with respect to the mating end of the terminal member. The through hole has a second portion extending through a rear end of the terminal member and sized for receiving the outer coating of the fiber optic cable. Projections are formed in the second portion of the through hole for clamping the outer coating to prevent lengthwise movement of the fiber optic cable relative to the terminal member.

  • Patent number: 4072419
    Abstract: A frame count cuer for controlling the operation of a continuous photographic film printer either of the continuous motion or incremental motion type. As the "preprint" film and the overlaying "raw stock" are passed through the printer, a signal is generated corresponding to the quantity and direction of travel of the film drawn across the exposure aperture. A counter is incremented or decremented by the signal and provides an integral footage and frame count of the amount of film passing through the printer. The information from a punched scene length tape is used to set a storage unit to the desired scene length and the setting of the storage unit is compared with the counter by a coincidence detector. Upon coincidence, a cue signal is fed from the coincidence detector to the printer light valve control unit. The light valves are preset with the information obtained from a punched paper tape in accordance with the predetermined preferred light level and the hue for the scene to be printed.
