The present invention provides a stainless steel wire for a carcass of a tire and a process for making such a wire. The wire comprises at least 0.02% and at most 0.2% carbon, at least 3% and at most 20% nickel, at least 12% and at most 28% chromium, the sum of the nickel and chromium being at least equal to 20% and at most 35% (% in weight). The structure of the steel comprises at least 20% in volume of martensite and it is devoid of austenite or it comprises less than 80% of it in volume.

A wire rope is formed by twisting two different metal wires which vary from each other by at least 50% in their loss factors. The two different metal wires are combined in two embodiments: first, wires of steel material and wires of titanium containing material, or secondly, wires of a steel material and wires of chromium stainless steel material. In a preferred embodiment, a wire rope is formed by twisting a plurality of strands around a center core and two different metal wires as described above are employed to form the strands.

A two-layer multistrand metal cord includes an inner cord layer and an outer cord layer. The inner cord layer is formed of K>1 inner strands, which are wound in a helix. The outer cord layer is unsaturated and formed of L>1 outer strands, which are wound in a helix around the inner cord layer. Each strand of the inner cord layer and the outer cord layer includes an inner strand layer and an outer strand layer. The inner strand layer is formed of two inner wires. The outer strand layer is formed of N outer wires, which are wound in a helix around the inner strand layer.

Process for treating a body of steel to promote its adherence to a composition which includes at least a rubber, containing the following points: a body at least the surface of which is of stainless steel is used, this steel containing at least 0.02% and at most 0.2% carbon, at least 3% and at most 20% nickel, at least 12% and at most 28% chromium, the sum of the nickel and the chromium being at least equal to 20% and at most equal to 35%, all of these percentage values being by weight; the structure of the steel includes at least 20% by volume of martensite and is without austenite or it comprises less than 80% thereof by volume; the surface of the body is activated and then treated with at least one starting silane so that it is covered with a film constituted only, or substantially only, of one or more silanes, in such a manner that this surface treated in this way can be placed directly in contact with the composition. Articles comprising a rubber composition and a metal body which has been treated in accordance with the process of the invention, such articles being for instance tires.

A patient lifting device includes an infection control lift strap with an inner core and an outer plastic layer that can be easily and effectively cleaned with standard disinfectant. The lift strap includes a waterproof sealed belt clamp assembly. A winch assembly includes a motor and high-efficiency gear assembly that lifts and lowers the strap with a spool assembly including an eccentric cylindrical spool. The eccentric cylindrical spool eliminates inconsistent performance of the lifting device as the strap drapes and coils onto the spool without raised attachment points. The strap includes top and bottom layers with different coefficients of friction to prevent slipping and self-tightening of the strap on the spool. The lifting device includes a thickness roller, a strap guard, and an electro-mechanical brake that locks the motor and prevents back driving. The gear assembly provides back driving when power is removed and the brake is released.

A load bearing assembly (100) for use in elevator system wherein the load bearing assembly (100) comprises at least one steel rope (102) and a jacket (110) surrounding this at least one steel rope (102). The jacket (110) comprises at least one layer of a thermoplastic elastomer comprising polymer particles (112). The polymer particles (112) have a molecular weight higher than 0.5*106 g/mol. The jacket (110) provides a coefficient of friction allowing sufficient traction between the load bearing assembly (100) and other components of the elevator system, such as the sheaves. Also disclosed is a corresponding method of making a load bearing member.
