    摘要: A process and apparatus for controlling the feed of an optical fiber or a plurality of optical fibers into a tube while the tube is being formed is disclosed. The process comprises the steps of propelling one or several fibers into a tube with a sufficient force to move the fibers at a speed faster than the speed at which the tube is formed, and of regulating the excess length of fiber by restraining the feed of fiber into the tube at a predetermined ratio with respect to the speed at which the tube is being formed.

    摘要: A process for producing thin walled coatings on elongated substrates by the electrostatic application of two superimposed layers of powder material is disclosed. The process comprises the steps of applying electrostatically a first layer of fusible powder material to an elongated substrate, at least partially fusing such first layer of powder material to provide a uniform coating on the elongated substrate, holding the at least partially fused coating at an elevated temperature below the full fusion temperature of the powder material to be applied as the second layer immediately prior to the application of such second layer, applying electrostatically a second layer of fusible powder material to the first layer, and fusing the total applied coating to achieve the desired coating thickness.

    摘要: A reel holder and clamping arrangement for a strander cradle is disclosed. The reel holder and clamping arrangement comprises two pintle assemblies each incuding a bearing housing, a pintle rotatably mounted in the bearing housing and means for mounting each bearing housing in axial alignment one on each side frame member. First cam means are associated with at least one of the pintle assemblies for moving its associated pintle along the axis of the reel for clamping a reel between the pintles. A reel holder engages the flanges of the reel when the reel is received within the cradle for positioning the core of the reel in alignment with the pintles of the pintle assemblies. Second cam means are associated with at least one of the pintle assemblies for moving the reel holder out of engagement with the flanges of the reel when the reel is clamped between the pintles. Means are provided for simultaneous actuation of the first and second cam means to clamp the reel between the pintles and free the flanges of the reel from the reel holder.

    摘要: A cable assembly for detecting the ingress of water inside a cable is disclosed. The cable assembly comprises a moisture detecting tape constructed of two parallel bare conductors laminated to an insulating substrate. The tape thus constructed is applied in an open helix around the conductor core of a cable. A suitable plastic jacket is extruded over the cable core and the moisture detecting tape. A shielding tape may also be applied over the cable core and the moisture detecting tape prior to extrusion of the overall plastic jacket. The cable thus constructed with the integral moisture detecting tape is adapted for connection to a suitable sensing apparatus at one end, and should moisture enter the cable as a result of damage to same, the electrical characteristics of the detecting tape would change and such change will result in a measurable conductance between the conductors of the moisture detecting tape. The ingressing water is thus sensed prior to penetrating and compromising the cable core. Standard bridge techniques are employed to determine the distance of the fault from the ends of the cable.
