In February 2008, American Standard Americas merged with two other plumbing fixture companies, Crane Plumbing and Eljer to create American Standard Brands. [10] The Crane Plumbing unit includes the former Universal-Rundle product line which Crane acquired in 1995 and continues to support with repair parts. [ 11 ]
An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. [1] An actuator translates such an input signal into the required form of mechanical energy.
The Rolls-Royce Trent 7000 is a high-bypass turbofan engine produced by Rolls-Royce, an iteration of the Trent family exclusively powering the Airbus A330neo. Announced on 14 July 2014, [ 2 ] and first run on 27 November 2015. [ 1 ]
By connecting linkages to the nut, the motion can be converted to usable linear displacement. Most current actuators are built for high speed, high force, or a compromise between the two. When considering an actuator for a particular application, the most important specifications are typically travel, speed, force, accuracy, and lifetime.
Electro-hydraulic actuators (EHAs), replace hydraulic systems with self-contained actuators operated solely by electrical power. EHAs eliminate the need for separate hydraulic pumps and tubing, because they include their own pump, [1] simplifying system architectures and improving safety and reliability. This technology originally was developed ...
Kursk was a Project 949A Antey (Oscar II-class) submarine, twice the length of a 747 jumbo jet, and one of the largest submarines in the Russian Navy.. On the morning of 12 August 2000, Kursk was in the Barents Sea, participating in the "Summer-X" exercise, the first large-scale naval exercise planned by the Russian Navy in more than a decade, and also its first since the dissolution of the ...
A plasma actuator induces a local flow speed perturbation, which will be developed downstream to a vortex sheet. As a result, plasma actuators can behave as vortex generators. The difference between this and traditional vortex generation is that there are no mechanical moving parts or any drilling holes on aerodynamic surfaces, demonstrating an ...
Reorganized and redesigned 15 February 1957 as Headquarters and Headquarter Company, 141 Signal Battalion (organic elements constituted 11 February 1957 and activated 15 February 1957 at Fort Polk, Louisiana) Inactivated 23 December 1957 at Fort Polk, Louisiana (Company A activated 24 September 1960 at Fort Hood, Texas)
