A transmission belt is provided which has a first elastomeric material, a plurality of longitudinal inserts comprising a first material, a working surface covered by a covering including a second material, and an opposite surface to said working surface. At least one of the first material and the second material is a fibrous metallic material. Advantageously, the transmission belt is a toothed belt.

A load bearing tension member for an elevator system includes a plurality of tension elements arrayed across a tension member width. The tension elements are offset from a tension member central axis, the central axis bisecting a tension member thickness and extending across the tension member width. The tension elements include a plurality of fibers extending along a length of the tension element, and a matrix material in which the plurality of fibers are embedded. A jacket at least partially encapsulates the plurality of tension elements.

The present invention relates to a transmission belt providing a belt member, and at least one RFID tag attached to the belt member, the at least one RFID tag including an integrated circuit, and an antenna connected to the integrated circuit for transmitting a signal indicative of a state of the transmission belt. The signal indicative of the state of the transmission belt is determined on the basis of a current deflection of the antenna.

The present invention relates to a process for electroplating an adhesive composition onto at least one conductive element, in which the conductive element is placed in contact with the adhesive composition comprising: a phosphate salt and a resin based on: a compound A1, compound A1 being chosen from a compound A11 comprising at least two functions, one of these functions being a hydroxymethyl function and the other being an aldehyde function or a hydroxymethyl function, or a compound A12 comprising at least one aldehyde function, or a mixture of a compound A11 and of a compound A12; and a phenol A21. A potential difference is applied between the conductive element and the adhesive composition to coat the conductive element with an adhesive layer.

Compositions for material layers suitable for use in power transmission belts are described. The composition includes millable polyurethane, such as polyester-based millable polyurethane or polyether-based millable polyurethane, such that material layers formed from the composition are solid but pliable. The disclosed material layers can be used to form the main body portion of power transmission belts, such as synchronous belts, V-belts, and micro-V belts.

A belt for use as for example an elevator belt, flat belt, synchronous belt or toothed belt comprises steel strands held in parallel by a polymer jacket. The steel strands have a diameter ‘D’ and are separated by a pitch ‘p’. The ratio of diameter ‘D’ over pitch ‘p’ is larger than 0.55. Such belt arrangement prevents the cutting of the polymer jacket between strand and pulley and abates the noise generation during use. The belts are best built with a type of parallel lay strands particularly designed for use in a belt. These strands do not show core migration during use of the belt.

A belt for drive systems includes: an elastic and flame-retardant belt body made from a polymeric material and at least one flame retardant additive, the belt body having a cover layer as a belt back and a substructure which has a force transmission zone; and a tension member embedded in the belt body, wherein the belt body is partially or completely provided with a coating, which coating is single- or multi-layered.
