Stihl was founded in 1926 by Andreas Stihl, an innovator in early chainsaw production. Stihl says it is the world's best-selling brand of chainsaws and the only chainsaw manufacturer to make its own saw chains and guide bars. [4] Andreas Stihl AG is a privately held company owned by the descendants of Andreas Stihl.
A crosshead as part of a reciprocating piston and slider-crank linkage mechanism. Cylindrical trunk guide Hudswell Clarke Nunlow; crosshead and two slide bars. In mechanical engineering, a crosshead [1] is a mechanical joint used as part of the slider-crank linkages of long stroke reciprocating engines (either internal combustion or steam) and reciprocating compressors [2] to eliminate ...
In the 1980s, many U.S. production engine remanufacturers began reaming valve guides, rather than replacing them, as part of their remanufacturing process. They found that by reaming all the valve guides in a head to one standard size (typically 0.008 in. diametrically oversized), and installing remanufactured engine valves having stems that are also oversized, a typical engine head can be ...
A barring engine (also called barring motor) is a small engine that forms part of the installation of a large engine, and is used to turn the main engine to a favourable position from which it can be started.
Buildings are often heated with electric heaters where grid power is available. Electric stoves and ovens use Joule heating to cook food. Soldering irons generate heat to melt conductive solder and make electrical connections. Cartridge heaters are used in various manufacturing processes.
Depending upon the application, a higher temperature may open a contact (as in a heater control) or it may close a contact (as in a refrigerator or air conditioner). The electrical contacts may control the power directly (as in a household iron) or indirectly, switching electrical power through a relay or the supply of natural gas or fuel oil ...
3003 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It can be cold worked (but not, unlike some other types of aluminium alloys, heat-treated) to produce tempers with a higher strength but a lower ductility. Like most other aluminium-manganese alloys, 3003 is a general-purpose alloy with moderate ...
