also : a blank row in lieu of these people (2) : a unit inside the rhythmic construction of verse formed because of the grouping of several the smallest units of the rhythm (for example metrical toes) The poem consisted of 14 lines.
: a geometric element that's formed by a shifting level and that has length but no width or thickness Particularly : this sort of an element which is straight
Most units consist of a brake to prevent the wires from unravelling completely if a wire breaks or stress is shed. German programs ordinarily use an individual massive tensioning pulley (generally a ratchet mechanism) by using a toothed rim, mounted on an arm hinged for the mast. Normally the downward pull from the weights plus the reactive upward pull on the tensioned wires carry the pulley so its tooth are very well clear of a stop to the mast.
On overhead wires suitable for trolley poles, That is carried out by aquiring a neutral area between the wires, necessitating an insulator. The driver with the tram or trolleybus need to quickly decrease the ability draw ahead of the trolley pole passes by means of, to circumvent arc damage to the insulator.
Portals are sometimes employed on two observe railways about bridges and viaducts or where by floor conditions are bad. It is because portals inflict fewer rotational forces on their foundations.
e : any of the successive horizontal rows of photograph aspects within the screen of the cathode-ray tube (such as a tv display screen)
Where by weights are utilised, they slide up and down on a rod or tube connected towards the mast, to circumvent them from swaying. Not too long ago, spring tensioners have started for use. These devices consist of a torsional spring having a cam arrangement to be certain a constant used tension (in place of varying proportionally with extension). Some products also consist of mechanisms for altering the stiffness of the spring for simplicity of routine maintenance.
The mechanical here teleprinter was replaced by a "glass tty", a keyboard and screen emulating the teleprinter. "Smart" terminals permitted additional functions, such as cursor motion around your complete monitor, or area enhancing of information about the terminal for transmission to the computer. Because the microcomputer revolution replaced the normal �?minicomputer + terminals �?time sharing architecture, components terminals ended up replaced by terminal emulators �?Computer software program that interpreted terminal signals despatched throughout the Personal computer's serial ports.
Interactive command-line sessions: After start, a method may well give an operator with the independent means to enter instructions.
Two wire operates over two tracks supported and registered by a single mast positioned within the centre in the tracks with cantilever arms connected to reverse sides. Frequently utilized on tram and light-weight rail devices but can surface on heavy rail lines.
B&O's overhead third-rail process at Guilford Avenue in Baltimore, 1901, Portion of the Baltimore Belt Line. The central position on the overhead conductors was dictated by the many tunnels at stake: the �?shaped rails ended up Situated at the best stage during the roof to provide probably the most clearance.[nine] Offered minimal clearance like in tunnels, the overhead wire may well be replaced by a rigid overhead rail. An early illustration was within the tunnels with the Baltimore Belt Line, exactly where a Π part bar (fabricated from 3 strips of iron and mounted on Wooden) was employed, with the brass Get hold of operating Within the groove.
On curves, the "straight" wire in between the supports brings about the Call stage to cross in excess of the floor of your pantograph because the practice travels round the curve. The motion of the Make contact with wire over the head with the pantograph is known as the "sweep".
Below DOS, in which the default command-line solution character is usually improved from / to -, programs might query the SwitChar API so as to find out The present environment.
25 kV AC neutral zone in Romania Within the Pennsylvania Railroad, stage breaks have been indicated by a place mild signal encounter with all eight radial positions with lenses and no Centre light-weight. In the event the period split was Energetic (the catenary sections from phase), all lights were lit.
