    摘要: A method and apparatus (200) for converting an analog voice channel signal and a 4-wire digital signal into a single 2-wire digital signal which can be transferred over a single twisted pair line (205). In one aspect, the method comprises the steps of converting the analog voice channel signal into a first binary signal, converting the 4-wire digital signal into a second binary signal, combining the first binary signal and the second binary signal into a higher rate binary signal, and converting the higher rate binary signal into a 2-wire digital signal which can be transmitted to another location over a single twisted pair line. In another aspect, the method comprises the steps of converting a 2-wire digital signal to a higher rate binary signal, separating a first binary signal and a second binary signal from the higher rate binary signal and converting the first binary signal into an analog voice channel signal, and converting the second binary signal into a 4-wire digital signal. The apparatus (200) includes an easily installed voice plus digital data remote terminal (203) and voice plus digital data central office terminal (201). The apparatus can provide a 3-to-1 pair gain by multiplexing signals representing the analog voice telephone signals and 4-wire digital data signals.

    摘要: A coaxial locking cable connector is described which when used in conjunction with a port adaptor precludes the use of a standard connector and provides increased security for signals emanating from a cable tap port or drop. A connector optionally includes redundant environmental sealing. An additional embodiment of the invention is an adaptor to adapt a standard cable spice or tap port to accept the connector and preclude acceptable standard coaxial connectors.

    摘要: A liquid crystal light composite in which discrete volumes of a liquid crystal material are dispersed in a matrix material is produced by a process in which a reactive additive formulation is added and photopolymerized. The reactive additive formulation includes mono- and multifunctional compounds in specified proportions and a photoinitiator. The reactive additive formulation reduces the operating field and may also improve other electro-optical properties.

    摘要: A re-enterable seal (25) for sealing an elongate object (16) passing through a barrier (24) between two environments (53, 54) includes an invertible enclosing member (30) containing a sealant (40). The sealant (40) is adhered to the inside surface (31) of the enclosing member (30). During insertion of the elongate member (16), the enclosing member (30) is inverted inside-out, with the sealant remaining on the inside surface (31) (now positioned outside the enclosing member). The elongate member (16) is then pulled back, causing the enclosing member (30) to re-invert, and bringing the sealant (40) into sealing compression against the elongate member (16).

    摘要: A coaxial cable connector is provided for installation and use with a prepared end of a coaxial cable. The connector comprises a body and a nut threadably tightenable to the body. The body includes a center pin chuck for engaging the center conductor of the cable when the nut assembly is tightened to the body. The nut defines an interior space including a mandrel assembly which is freely rotatable within the interior space until the nut is tightened to the body. The mandrel assembly includes an insulator cone for guiding the center conductor; it includes a clamping arrangement for engaging and clamping the center pin chuck as the nut is tightened to the body. The assembly further includes a mandrel which is slideably mounted under the cable outer metal jacket in a space provided after removal of a portion of the dielectric core incident to preparation of the cable end. A ferrule is slidably mounted over the outer jacket and the ferrule includes collet fingers disposed over a portion of the mandrel. The mandrel includes a ferrule collet closure for closing the collet fingers of the ferrule to cause them to compress the outer metal jacket against the portion of the mandrel as the nut is tightened to the body of the connector during installation of the connector to the prepared cable end.

    摘要: A telecommunications gas tube apparatus (40) which is suitable for connection to a gas discharge tube (12) and which comprises an electrically non-linear resistive element (45) prepared from an electrically non-linear composition which comprises a polymeric component and a particulate filler. The composition has an initial resistivity ςi at 25 °C of at least 109 ohm-cm, and is such that a standard device containing the composition has an initial breakdown voltage V¿Si?, and after the standard device has been exposed to a standard impulse breakdown test, the device has a final breakdown voltage VSf which is from 0.7VSi to 1.3VSi. In addition, the composition in the device has a final resistivity ςf at 25 °C of at least 10?9¿ ohm-cm. Such compositions are useful in providing both vent-safe and fail-safe protection to a gas discharge tube (12).
