Exactly where weights are employed, they slide up and down on the rod or tube connected on the mast, to avoid them from swaying. Not long ago, spring tensioners have started off for use. These products consist of a torsional spring that has a cam arrangement to guarantee a relentless utilized pressure (as an alternative to various proportionally with extension). Some gadgets also contain mechanisms for modifying the stiffness from the spring for ease of routine maintenance.
The mechanical teleprinter was replaced by a "glass tty", a keyboard and monitor emulating the teleprinter.
