A hoisting device rope has a width larger than a thickness thereof in a transverse direction of the rope. The rope includes a load-bearing part made of a composite material, the composite material including non-metallic reinforcing fibers, which include carbon fiber or glass fiber, in a polymer matrix. An elevator includes a drive sheave, an elevator car and a rope system for moving the elevator car by means of the drive sheave. The rope system includes at least one rope that has a width that is larger than a thickness thereof in a transverse direction of the rope. The rope includes a load-bearing part made of a composite material. The composite material includes reinforcing fibers in a polymer matrix.

A forming device for forming links in the shape of a Möbius strip includes a rotation module with an inner path. The forming device has a widening for 180° rotation of a strip introduced into the rotation module. The rotation module has an inlet suitable for one end of a strip, an outlet suitable for the strip and the inner path extends from the inlet to the outlet. The widening is adapted for rotation of the end of the strip 180° about its longitudinal axis. The device also includes a gas injector positioned at the inlet of the rotation module intended to drive the strip through the inner path of the rotation module.

The invention can be used in the production of prestressed reinforcement. The problem of interest consists in developing a reinforcing cable having an increased degree of bonding, said cable having guaranteed structural stability and providing an increased degree of bonding with concrete, durability, and stress relaxation resistance. In a reinforcing cable, a central wire (1) is disposed along the axis of the cable, and is configured with spiral grooves (2) having a pitch that is equal to the pitch of the lay of the cable. Strand wires of an inner layer are disposed within the grooves, each of said wires being in contact with the central wire and with two adjacent wires of the inner layer. Strand wires are helically arranged at equal intervals from one another in an outer layer, each of said wires being disposed in a groove between the strand wires of the inner layer, and being in contact with the latter.

A process and a splitter for splitting a tape of a uniaxially oriented material. The tape is passed in a process direction over a static splitting profile having a row of teeth, e.g., with a cutting edge extending in the process direction. The tape is split to form a material comprising a plurality of parallel strips interconnected by fibrils. The split material can for example be used for the production of high tensile ropes or laminates.

The present invention is directed to a cold cutting polypectomy snare. The cold cutting polypectomy snare has a cross section optimized for polypectomy. In some embodiments, the snare may have a uniform cross section along a length of the snare. In other embodiments, the snare may include a first side and a second side, wherein the first and second sides each have a unique cross section. Further, the cross-sections of the first side and the second side can be configured to couple together when a diameter of the snare is decreased to affect a cutting of a polyp.
