Method of making a cord and polymer jacket assembly having a flame retardant in the polymer jacket material

An illustrative method of making an elevator load bearing member having at least one elongated tension member at least partially covered by a jacket includes mixing a flame retardant with a polymer material. The flame retardant is selected from a group consisting of (i) a halogen-free melamine based intumescent comprising melamine cyanurate, melamine-phosphate, melamine pyrophosphate or melamine polyphosphate in an amount up to about 20% by weight of the thermoplastic polymer or (ii) a filled polymer having a nanoscale filler chemically bonded to a matrix phase. Applying the mixed flame retardant and polymer material to the tension member forms a jacket of a desired shape.

Thimble assembly for a cord

A thimble assembly that includes an arch portion connecting a first leg portion to a second leg portion. The thimble assembly may also include a peripheral groove extending substantially along an outer surface of the first and second leg portions and the arch portion. The thimble assembly may also include a plurality of connectors extending from a first lip of the peripheral groove and connecting to a second lip of the peripheral groove. The connectors may traverse the peripheral groove across the first and second leg portions and the arch portion. The thimble assembly may include a length of cord with a plurality of strands that traverses the peripheral groove. The strands may enclose the connectors such that the strands are woven around the connectors. In one embodiment, the thimble assembly may include a wireless tension detector connected to the thimble that includes a sensor that senses radial expansion and contraction of the cord under tension. The wireless tension detector may include an alert signal to indicate when expansion and contraction of the cord is not within a predetermined range.

HYBRID STRANDED CONDUCTOR

A hybrid strand includes a core and outer wires arranged around the core, wherein at least a part of the outer wires is compressed, wherein the compressed outer wires include a flattened cross-sectional shape, the outer wires are composed of steel, and the core is a fiber core. A corresponding production method produces such a hybrid strand.

FUSE ASSEMBLY HAVING INLINE TRIGGER FOR CONTROLLED FAILURE AND ROPE SYSTEMS CONTAINING THE SAME

A fuse assembly for rope systems. A catch is a rope segment having a certain failure strength. An accompanying trigger component has a predetermined failure point which can be less than the failure strength of the catch, acting as a sacrificial element to reveal the potential risk of rope recoil. In one embodiment, the catch includes connecting ends, and the trigger is remote from the catch. In other embodiments the trigger includes the connecting ends and the catch is separate from but works cooperatively with the trigger. Additional hold components can accompany the system, as well as first and second chafe protection layers.

A method for attaching an anchor to an end of a tensile member by inverting the assembly of anchor and tensile member and injecting pressurized potting compound. A length of filaments of the tensile member are placed within a cavity through the anchor. The anchor and filaments are placed in an inverted position, with the distal end of the anchor facing downward and the cable extending upward out of the anchor. If the anchor has an open distal end this is sealed. Liquid potting compound is injected into the anchor cavity and allowed to solidify. During the solidification process, a controlled translation (pulling) of the cable is preferably introduced.

A security device has a flexible strap (26) with a lock unit (28) attached at each end. The strap (26) comprises a plurality of longitudinally extending multi-filament cables or ropes (2) arranged in a substantially planar array embedded in an elastomeric material (4). The cables or ropes (2) have a coating of primer for creating a bond with the elastomeric material (4). The primer may be restricted to the external surface of the cables or ropes (2), or some of the surfaces of the filaments may be free of primer. This facilitates relative movement of the filaments during flexure or compression of the strap (26). Moreover, an extrusion process for manufacturing the strap (26) including a priming station (12) is disclosed.
