Abstract: An assembly for curing a linear work product which is passed through a curing oven at high speed along a first path the assembly having a first path altering member, such as a sheave, re-directing the work product through the oven along at least a second path spaced from the first path. A plurality of such sheaves in a first embodiment redirect the work product through the entrance end of the oven for travel along a second path in the same direction as in the first path. In a second embodiment, the path altering members re-direct the work product into the exit end of the oven for travel in a second path in the opposite direction to the first path. Additional curing may be realized by passing the work product through the curing oven in the same or in opposite directions, as desired or as necessary.

Abstract: An electrical connector housing assembly is provided having a plug assembly and cap assembly matable with one another to form a wire to wire, wire to board or wire to device connection. The plug assembly is formed with a latching member thereon, while the cap assembly is formed with a connector position assurance device (CPA) thereon. The overall envelope of the connector housing assembly is reduced by dividing the latch member and CPA between the plug and cap housings. Keying features are formed integrally with plug and cap terminal position assurance devices (TPAs) to ensure proper orientation between the plug and cap and to further assure that each plug is connected to the corresponding cap. The overall envelope is further reduced by forming the keying features internal to the housings upon the TPAs.

Abstract: The invention provides a polynuclear compound comprising two or more metal-hapto-3-capped nidocarborane groups. Also provided is the use of such a compound as a catalyst in a chemical reaction such as a hydrogenation or oxidation reaction.

Abstract: The present invention provides an apparatus for cleaning an optical fiber ribbon without splitting the ribbon. The apparatus comprises a first element that has a channel formed therein, which preferably has a width that is substantially equal to the width of an optical fiber ribbon. A ribbon is cleaned by disposing it in the channel and by pulling it through the channel while applying a force to the top surface of the ribbon. The force may be applied, for example, by a user who applies a cleaning cloth to the top surface of the ribbon as it is pulled through the channel. The contact between the channel, the cleaning device and the exterior surface of the ribbon effectuates removal of foreign material from the exterior surface of the ribbon. In accordance with the preferred embodiment, the apparatus further comprises a second element. The second element includes a bottom surface that is disposed over the channel when the first and second elements are placed in their operative positions.

Abstract: A buffer encasement has a longitudinally extending interior surface that extends around and defines a longitudinally extending passage containing a stack of optical fiber ribbons. The interior surface closely bounds the stack, and the buffer encasement is easily removable from the stack. The buffer encasement can be is easily removable from the stack because the buffer encasement is thin and is constructed of a material that is capable of being easily torn. The buffer encasement can be is easily removable from the stack because the buffer encasement defines a longitudinally extending weakened portion that is capable of being more easily torn than the remainder of the buffer encasement. The weakened portion is operative so that when the weakened portion is torn the buffer encasement defines longitudinally extending edges on the opposite sides of the tear. The edges can be separated from one another to define an opening therebetween through which the stack of optical fiber ribbons can be accessed.

Abstract: An optical module includes a stack of optical fiber ribbons that are within a buffer encasement, such as a thin sheath, that closely bounds the periphery of the stack. The optical modules can be rectangular, so that the optical modules can be readily stacked in a manner that results in a very space efficient fiber optic cable. The optical modules can be tested prior to being incorporated into the fiber optic cable so as to maximize the probability of the fiber optic cable being fully operable. The sheath cushions all of the sides of the stack. In some optical modules, the stack is movable relative to the sheath and the optical fiber ribbons are movable relative to one another.

Abstract: A fiber optic cable includes multiple differently sized stacks of optical fiber ribbons. The stacks include a central stack that is approximately centrally located in a jacket passage and peripheral stacks positioned radially around the central stack. A difference exists between the dimensions of the central stack and the dimensions of one or more of the peripheral stacks. Another fiber optic cable has multiple longitudinally extending stacks of optical fiber ribbons that are within a jacket passage. The stacks include a central stack that is approximately centrally located in the jacket passage, and peripheral stacks positioned radially around the central stack. Buffer encasements that respectively contain the peripheral stacks are longitudinally stranded around the central stack.

Abstract: A stack of optical fiber ribbons is enclosed in a buffer encasement having a relatively soft inner portion and an relatively hard outer portion. The inner portion has an interior surface extends around and defines a longitudinally extending passage that contains the stack, and the interior surface closely bounds the stack. The outer portion extends around, closely bounds and contacts the inner portion, and has a modulus of elasticity that is greater than the modulus of elasticity of the inner portion. In accordance with one example of the invention, the inner portion has an exterior surface that extends around and is spaced apart from the passage, and the outer portion has an interior surface that extends around, closely bounds, and engages the exterior surface of the inner portion, whereby the buffer encasement has multiple plies. In contrast, in accordance with another example of the invention, a surface is not defined between the inner portion and the outer portion.

Abstract: An optical fiber ribbon capable of being divided into two or more robust sub-units along predetermined dividing lines has a plurality of optical fibers in a substantially flat array which have a first, low, matrix-to-fiber coating, which may be a coloring ink, adhesion for facilitating mid-array or mid-span fibers access. The two fibers on either side of each of the dividing lines and adjacent thereto and to each other, have an enhanced or high matrix-to-fiber coating adhesion whereby the sub-units created by the division are sufficiently robust to retain the fibers within the matrix.

Abstract: An optical fiber ribbon in which a plurality of optical fibers are held in an array has a matrix material for bonding to the fibers to form the ribbon. The matrix material has certain characteristics which serve to enhance fiber access, among which are an elastic modulus from 600 to 1200 MPa at room temperature, from 100 to 280 MPa at 100.degree. C., and from 15 to 45 MPa at temperatures greater than 170.degree. C. The matrix material swells in ethanol more than 15% by volume within 20 minutes, and is virtually immune to the action of cleaning solvents. The matrix material has a surface tension of 20-35 mJ/m.sup.2 as do the color coding inks which identify the fibers.
