Abstract: Methods and apparatus are provided for delivery of telecommunications data over fiber. In one exemplary embodiment, there is provided a fiber distribution hub including a distribution panel mounts, and the distribution panel mounts are configured to receive distribution panels, while the distribution panels are configured for establishing a connection between a feeder cable and a distribution cable, and at least one of the distribution panel mounts is not attached to a distribution panel.

Abstract: A fiber optic connector may include a first cover with an integral restraining mechanism and a second cover with a reciprocal restraining mechanism. A fiber optic cable having a ferrule at a terminating end may be placed within the fiber optic connector. A dust cap may be placed on the terminating end of the fiber optic cable. The integral restraining mechanism and the reciprocal restraining mechanism may detachably mate and enclose the terminating end of the fiber optic cable within the fiber optic connector. The fiber optic connector may include one or more gaskets to assist in sealing the connector.

Abstract: A fiber optic drop ribbon is described that can be attached to structures, such as the walls of multi-dwelling units (MDUs), for connecting subscribers to a fiber optic communications network. A number of coated optical fibers are supported by a backing strip of the article having a first and second surface. The first surface is attached to the structure, and the optical fibers are attached to the second surface. A cover strip attaches to the second surface of the backing strip to cover the optical fibers. The cover strip may be removable to provide access to the optical fibers and may reattach to the backing strip following removal. Associated systems and methods are also provided that may include additional components, such as furcation sections, furcation splints, and fiber trays, to facilitate the installation of the article and the connection of subscribers to the fiber optic network.

Abstract: A multiple dwelling unit (MDU) optical fiber splitting unit (FBU). One or more fiber strands enters the FBU at the MDU. Each strand may be connected to a variable attenuator. Each strand is subject to a one to four split. Each of the four split fibers is connected to an optical connection interface such as an SC/ACP connector. Each optical output is connected to an MDU-ONT that supplies an optical interface to copper and cable infrastructure, enabling fiber-based services to be provided to units in an MDU with reduced installation costs and utilization of existing twisted pair and coaxial distribution lines.

Abstract: In the process for recovery of Group VIII noble metal carbonylation catalyst from a process stream which also contains tar produced during a carbonylation process for carboxylic acid anhydride production, the process stream is diluted with alkyl halide and then extracted with a water, carboxylic acid, iodide salt alkyl halide solution, the iodide salt being a co-promoter derived from the carbonylation process. The recovered noble metal may be recycled to the carbonylation process with iodide salt co-promoter.

Abstract: A process controller with power outage analysis capability uses a real time clock generator powered by an uninterruptible power source for providing a real time reference which is used to measure the actual duration of a process controller disabling power outage. A non-volatile memory is also powered by the uninterruptible power source and is used to store the maximum allowable outage time limit for a particular process being controlled. The clock generator is initialized at the start of the power outage by a power outage detector which provides an early warning of an imminent power outage.

Abstract: Dyestuffs having the general formula: ##STR1## wherein Z.sup.1 and Z.sup.2 each independently represent oxygen or ##STR2## in which Y is hydrogen, an optionally substituted hydrocarbon radical or an acyl radical,R.sup.1 and R.sup.2 each independently represent a substituted or unsubstituted aryl radical, preferably phenyl, andX.sup.1 and X.sup.2 each independently represent hydrogen, halogen, cyano, alkyl, alkoxy, nitro, amino, substituted amino, carboxylic acid, carboxylic acid ester, optionally substituted carbamoyl, alkylthio, arylthio, alkylsulphonyl, arylsulphonyl, acyl, acyloxy, hydroxy, sulphonic acid or sulphonic acid ester, orX.sup.1 and X.sup.2 together form a 5- or 6-membered, carbocyclic or heterocyclic, saturated or unsaturated, including aromatic, ring which may carry further substituents; processes for the manufacture of these dyestuffs and their use for coloring aromatic polyester textile materials.
