Abstract: The present invention relates in general to portable first aid kits and, in particular, to a low profile first aid kit that is adaptable for a quick release from a carrier and can be easily stored and carried by a person. The design of the disclosed release system allows for the first aid kit to be released with one hand from a carrier with mounting capabilities. Additionally, the medical kit includes a dual purpose carrier strap that can either be wound around the first aid kit and operable to torque the kit for storage purposes when in the closed position, or used to carry the kit in the open position until it can be secured and subsequently stored.

Abstract: A balance for a horological movement, including rigid parts constituted by a hub defining the pivot axis of the balance, at least one felloe sector, at least one arm connecting the at least one felloe sector to said hub, and including a slot for receiving and gripping in position an inertia-block, the slot opening into a housing delimited on the one hand by a rigid part of the balance, and on the other hand an elastic arm including a first end integral with a rigid part of the balance, and a second free distal end. The elastic arm can have a body of a non-constant section, a part of the body having a greater thickness than the rest of the elastic arm so as to have a larger volume of material under stress and store a maximum of elastic energy.
