George Rae, Hawick, Great Britain
Assignee: Emetelle UK Limited, Hawick, Great Britain
A fiber optic cable (500, 700) comprises retractable fibre units (502)
extending in parallel with one another within an extruded polymer tube
(504). The fiber units are free to slide in the tube such that a selected
fiber unit (702a) can be accessed and re-directed by forming an opening
in a wall of the tube (504) and withdrawing the selected fiber unit
through the opening (710). Each fibre unit comprises two or more
optical fibers (506) embedded in a solid resin material (520) to form a
coated fibre bundle and an extruded polymer sheath (524). The fiber
optic cable is manufactured by feeding the fiber units through an
extrusion head (602) by which the extruded tube (504) is formed. The
sheath (524) of each fiber unit is primarily polyethylene. A lining (510) of
the extruded polymer tube is formed by polymer other than
polyethylene, for example polypropylene.

frequency and/or high speed signal transmissions by providing reliable
transmission paths between hardware components. An example cable
includes parallel conductors and a dielectric core that secures the
parallel conductors along the length using parallel channels in opposite
sides of the dielectric core. An alignment structure is also formed in the
dielectric core, which has a shape along the length of the cable. A cable
jacket surrounds the parallel conductors and the dielectric core. The
cable jacket is contoured to follow the shape of the alignment structure.
The dielectric core can be formed to maintain consistent separation
between the parallel channels along the length of the cable to match
impedance of the parallel conductors along the length of the cable,
whether the cable lays flat or bends around corners.

Steel Wire Rope, Coated Steel Wire Rope and Belt Comprising Steel Wire Rope
US Patent 11993894
Published May 28, 2024
Inventors: Eline De Roose, Torhout, Belgium; and Andreas Klust,
Heverlee, Belgium
Assignee: Bekaert Advanced Cords Aalter NV, Aalter, Belgium
A steel wire rope is presented for use in elevators and lifting
applications. The steel wire rope contains a core surrounded by multiple
strands. The outer filaments of the core and the outer filaments of the
strands are likely to contact one another during use. The outer steel
filaments of the core have an average Vickers hardness that is at least
50 Vickers hardness numbers lower than that of the outer filaments of
the strands. As the hardness of the outer filaments of the core is
substantially lower than that of the outer filaments of the strands, those
softer filaments will preferentially abrade away during use. In this way
the core is sacrificed while preserving the integrity of the outer
filaments of the strands. The use of this ‘sacrificial core’ results in a
higher residual breaking load after use.
