A spring applies force to close the door, which the dashpot offsets by forcing fluid to flow through an orifice, often adjustable, between reservoirs, which slows the motion of the door. Consumer electronics often use dashpots where it is undesirable for a media access door or control panel to suddenly pop open when the door latch is released ...
The backward motion of the escape wheel during part of the cycle, called recoil, is one of the disadvantages of the anchor escapement.It results in a temporary reversal of the entire wheel train back to the driving weight with each tick of the clock, causing extra wear in the wheel train, excessive wear to the gear teeth, and inaccuracy.
Honeywell Gent, formerly Gents' of Leicester, is a British manufacturer of life safety equipment based in Leicester, England.Established by John Thomas Gent, the company is thought to have started in 1872 however it could have been trading as early as the 1860s. [1]
The Beverly Clock as it now stands in the Physics Department at the University of Otago The inner mechanism of the Beverly clock showing chain, sprockets and torsional pendulum. The Beverly Clock [1] is a clock in the 3rd-floor lift foyer of the Department of Physics at the University of Otago, Dunedin, New Zealand.
[32] [33] The most accurate mechanical clock to date is probably the electromechanical Littlemore Clock, built by noted archaeologist E. T. Hall in the 1990s. In Hall's paper, [ 34 ] he reports an uncertainty of 3 parts in 10 9 measured over 100 days (an uncertainty of about 0.02 seconds over that period).
A schematic of a simple spring–mass–damper system used to demonstrate the tuned mass damper system. Tuned mass dampers stabilize against violent motion caused by harmonic vibration. They use a comparatively lightweight component to reduce the vibration of a system so that its worst-case vibrations are less intense.
This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to ...
Fire-Lite was the first company to introduce a compact, inexpensive addressable fire alarm control panel. [2] Some of their recognizable products include the Fire-Lite BG-10 pull station, introduced in 1983, and the newer BG-12 pull station, introduced in 1999. Fire-Lite is part of the Honeywell Life Safety Group, along with Notifier.
