Abstract: A speed changer is used to control derailleurs using cables from a single rotating handle, the deraileurs being connected respectively to an elastic return element. The speed changer includes at least two cable-maneuvering mechanisms. The mechanism for maneuvering the cable of the rear derailleur, which rotates integrally with the handle, can cause the rear cable to loosen or tighten when the handle is rotated in one direction. The speed changer is characterized in that the rotating assembly, formed by at least one mechanism for maneuvering the rear cable and the handle, can be connected to rotate intermittently with the mechanism for maneuvering the front cable of the front derailleur which, depending on the direction in which the handle is rotated, can cause the front cable of the front derailleur to tighten or loosen.

Abstract: A novel method of producing an odor-controlling textile is disclosed. More specifically, a textile structure is disclosed that contains thin breathable film layer having an activatable antimicrobial odor controlling material. Most specifically, the present invention relates to a textile composite that is composed of a flexible breathable film layer with a measurable gas or vapor transmission rate, that contains metallic silver, zinc and/or copper metallic ions, and is combined with fabric and/or foam layers to form an antimicrobial, odor and infection control laminated structure.
