Patent CA-2179209-A1 (CA)
Inventor: GRAHAM LIONELL
IPC: B29C48/94
Filed: 1996-06-17
Abstract: A simplex optical fiber cable of this invention includes an optical fiber, a buffer preferably of nylon, surrounding and in contact with the optical fiber, a yarn layer with strength fibers, preferably aramid fibers, disposed about the buffer and a sheath preferably formed of polyvinyl chloride (PVC) surrounding and in contact with the yarn layer. In cross-section, the simplex optical fiber cable has a diameter less than 2.0 millimeters (mm), and thus is much smaller in diameter than optical fiber cables presently available. Preferably, if the buffer is relatively thin providing limited protection to the optical fiber, a slick substance such as talc is applied to an outer surface of the buffer before the yarn layer is disposed thereon. The slick substance allows the buffer of the optical fiber to slide to a degree in contact with the yarn layer and thus reduces fatigue caused by axial movement of a ferrule of the connector terminating the optical fiber cable. On the other hand, if the buffer is relatively thick, a friction-reducing substance such as ModafloTM can be applied to the optical fiber to allow the buffer to be stripped relatively easily. A zip-cord duplex optical fiber cable of this invention includes essentially two simplex optical fiber cables with their respective sheaths joining at a middle portion along the axial length of the simplex optical fiber cables. Thus, in cross-section, the zip-cord duplex optical fiber cable has a figure-eight shape with a relatively thin portion in the middle which can be manually pulled apart to separate the zip-cord duplex optical fiber cable into separate simplex optical fiber cables. This feature of the invention allows the zip-cord duplex optical fiber cable to be split at its ends to allow connectors attached to respective ends of the optical fiber cables for connection to respective spaced connector receptacles. A second duplex optical fiber cable of this invention includes two simplex optical fiber cables arranged side-by-side with an oversheath extruded about and holding together the two simplex optical fiber cables. In cross-section, the two duplex optical fiber cables of this invention are less than 2.0 mm in height and 4.0 mm in width, and thus are much smaller than currently available duplex optical fiber cables. The invention also includes die assemblies and methods for making the simplex and duplex optical fiber cables.

IPC: B29C45/14
Filed: 1995-06-01
Abstract: A simple and inexpensive method and apparatus for molding a peripheral frame around a sheet or grid (30) of thermoplastic material to produce a framed panel. A peripheral frame, preferably of structural foam or the like, is injection molded about a thermoplastic sheet or grid of panel-forming material which has been previously drawn or stretched at a temperature which orients the molecules of the polymer, i.e. below the glass transition temperature of the polymer. Either during the frame molding process, or subsequent thereto, the panel-forming material is heated sufficiently to cause the material to shrink or revert toward its prestretched condition so as to tension the panel-forming material within the frame. Elastomeric sealing means (70) are disclosed for sealing the mold during injection of the frame-forming material and locating fingers (92) are provided to position a grid-like panel-forming material prior to initiation of the molding process. By the utilization of structural foam molding techniques, a panel of thermoplastic material may be integrally molded and tensioned within a rigid frame to produce a framed panel of any size for use as a barrier, a fence, a guard, a closure, a seat or bedding support, a filter member or other such applications.

Title: Transmission system with improved symbol processing
Inventor: PHILIPS NORBERT JEANNE LOUIS
IPC: H04L27/38
Filed: 1996-08-12
Abstract: In OFDM transmission use of an FFT is made for demodulating all carriers simultaneously. In order to prevent adverse influence of intersymbol interference due to multi path propagation, it is known to determine the impulse response of the transmission medium and to adapt the FFT window accordingly. According to the invention the centre of gravity of the impulse response is used rather than the first significant value of the impulse response. This has the advantage that the influence of deep fading has less influence on the selection of the FFT window, resulting in an improved performance.
