Le fouet à chaîne sert à démonter des cassettes montées sur corps de roue libre intégré au moyeu. Il permet aussi de démonter les couronnes des roues libres de type plus ancien. +
The fusion splicer is a tool which delivers fast and reliable fibre splicing under even harsh environmental conditions. It combines portability and ease of use in a ruggedized body. +
Isopropyl alcohol is a colorless, flammable chemical compound with a strong odor. It dissolves a wide range of non-polar compounds. Thus, it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils. +
A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a force perpendicular to the axis of spin (outward) that can be very strong. The centrifuge works using the sedimentation principle, where the centrifugal acceleration causes denser substances and particles to move outward in the radial direction. At the same time, objects that are less dense are displaced and move to the center. In a laboratory centrifuge that uses sample tubes, the radial acceleration causes denser particles to settle to the bottom of the tube, while low-density substances rise to the top. +
Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the material or the laser beam generated. A typical commercial laser for cutting materials involved a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas,[1] leaving an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials. +
A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power.[1] The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons). Industrial jacks can be rated for many tons of load. +
