摘要： The monitor system consists of a voltage controlled oscillator for produc an acoustic wave whose frequency is proportional to the voltage being measured. An acoustic waveguide is used for transmitting the wave to an electrically isolated acoustic to electrical transducer. The output of the transducer is amplified and then displayed on an appropriate readout calibrated in volts.

摘要： A passive voltmeter that measures pulses of high voltage by periodically charging a condensor through a spark gap. The frequency at which the spark gap breaks down is a function of the voltage being measured and is detected and displayed in volts. Radioactive material within the chamber is used to insure a constant breakdown voltage by supplying the necessary free electrons. This insures constant breakdown time for the arc with minimum jitter.

摘要： A cable spool has a cylindrical drum about which a length of cable is wound. A pair of end flanges connected to opposite ends of the cylindrical drum hold the cable on the cylindrical drum. One of the end flanges has an outer flange and an inner flange extension formed integrally therewith. A serpentine cable channel is formed in the inner flange and grips an end of the cable to prevent the cable from unwinding. The serpentine cable channel holds the cable end available for electrical or optical testing while holding it away from a periphery of the outer flange where the cable might be damaged by unwanted contact with an abrasive surface.

摘要： Signal/data enters the IC in optic form via an optically-efficient method om either fiber optic or circuit-trace optic waveguides. The optic signal/data is transformed to electrical signal/data via the photo-sensing cells that are illuminated by each channel's photon beam. This electrical signal then is transmitted via a connection to an IC chip which performs the required processing. This IC chip is supplied with electric power by means of a photo-voltaic cell array mounted internal to the IC package. The illumination source of the photo-voltaic array is provided by an optic waveguide that transmits a high intensity photon beam of proper wavelength to yield efficient photon-to-electric current conversion. A portion of this high intensity photon beam is captured by an optic waveguide mounted internal to the IC This optic waveguide conducts the photons to a region where photo-intensity modular cells are located. Each of these modulator cells is connected electrically to the output terminals of the IC and seerves to convert the electrical signal/data to an equivalent optic form by means of modulating a portion of the supplied photons and directing the modulated beam toward the output channel optic waveguide. This optic waveguide then transmits the signal/data to other optic-coupled IC's or transducers, as required.

摘要： A method and tool for accessing optical fibers contained in a buffer tube is provided. The buffer tube is held in a hourglass shaped bore formed by the mating engagement of first and second members. The mating engagement of the first second members also causes the engagement of cutting blades with the buffer tube. As the tool is drawn along the buffer tube, a chord of protective covering is removed from the buffer tube, providing access to the optical fibers held within.

摘要： A filler rod for occupying space in a stranded optical fiber communications cable having at least one buffer tube containing at least one optical fiber is disclosed. The filler rod comprises an elongated rod extruded from a polypropylene homopolymer, a polypropylene-polyethylene copolymer (i-PP) resin material, or preferably, from a polypropylene-polyethylene copolymer having a nucleating agent disbursed therein. The resin material is foamed during extrusion so as to have a plurality of void spaces therein and a relative density which is less than 1 relative to the unfoamed resin material. As compared to rods made from high density polyethylene, the i-PP filler rods show a greater foaming efficiency, more efficient use of material, an improved combination of mechanical properties and density, reduced post-extrusion shrinkage and a substantial reduction in the sticking of the filler rods to the outer jacket that is experienced with high density polyethylene filler rods.
