    摘要: A low-mass pointer element for a pressure measuring mechanism is made from a lightweight plastic paper material and includes a center hub having a through aperture which is sized to accommodate a rotatable shaft end of the pressure measuring mechanism. An indicating end of the pointer element is sloped downwardly toward a dial face relative to the center hub to prevent parallax along with a counterbalancing portion. The indicating end is inwardly tapered to a flattened distal end to provide equivalent stiffness, but with considerably less mass so as to significantly reduce stress loads on a corresponding movement mechanism.

    摘要: A fluid insensitive system for braking the displacement cables in an endoscopic insertion tube wherein at least one control wheel is mounted on the outside of the insertion tube control housing. A brake disc is mounted adjacent the control wheel and is moved in and out of engagement with the wheel by an actuator. A plurality of spring loaded detent pins are slidably carried within the control wheel for engaging a series of depressions in the brake disk to form a restraining ratchet mechanism.

    摘要: Two or three fiber optic cables, each adapted for a particular purpose is provided in the insertion tube of an endoscope/borescope for illuminating an object to be viewed. The proximal end of the insertion tube is positioned adjacent a source of light. A device is provided for rotating the proximal end of the insertion tube to position one or more of the fiber optic bundles in optical alignment with the source of light to illuminate the object to be viewed with the desired light. Alternatively, an individual bundle can be illuminated by insertion in a proper receptacle in an interconnecting module positioned in optical alignment with a light source.
