The multilayer wire rope spooling system has undergone continuous refinement over the years and adapted for any application where long lengths of steel wire ropes must be wrapped in multiple layers quickly and smoothly. Examples include: Cranes for construction sites, offshore oil rigs, ports or on board ships; Deep mining
The steep hill along Queen Anne Avenue has grades of up to 19 percent between Mercer and Comstock. [1] [a] The initial cable car service to the top of the hill that was completed in 1891 used a route north via Second Avenue from the existing cable car powerhouse at Denny Way and 2nd, west via Aloha Street to Queen Anne Avenue, then north via Queen Anne to the terminus at Highland Drive.

The three ropes are so tightly wound counter to the weave of the constituent ropes that the fibers are compressed and the individual weaves stressed, sealing out the water and resulting in a length of about 180 metres (100 fathoms), the UK traditional definition of cable length. Using a cable, the raising of the anchor, or any activity ...
For oilfield work, the wireline resides on the surface, wound around a large (3 to 10 feet in diameter) spool. Operators may use a portable spool (on the back of a special truck) or a permanent part of the drilling rig. A motor and drive train turn the spool and raise and lower the equipment into and out of the well – the winch.
A cable in this usage cable is a thick rope or by transference a chain cable. [1] The OED gives quotations from c. 1400 onwards. A cable's length (often "cable length" or just "cable") is simply the standard length in which cables came, which by 1555 had settled to around 100 fathoms (600 ft; 180 m) or 1 ⁄ 10 nautical mile (0.19 km; 0.12 mi). [1]
If the cable comes off the spool the same way it goes on, the internal 'lay' is preserved, and the cable isn't damaged or twisted internally. If a cable is straight coiled and then pulled from the coil, it has the effect as coiling cable on a spool and then pulling the cable off the top of the spool, imparting a twist in the cable with every ...
As in the Geiger counter, a particle leaves a trace of ions and electrons, which drift toward the case or the nearest wire, respectively. By marking off the wires which had a pulse of current, one can see the particle's path. The chamber has a very good relative time resolution, good positional accuracy, and self-triggered operation (Ferbel ...
Cable length or link length: Crosstalk creates interference between the parallel lines, and the effect worsens with the length of the communication link. This places an upper limit on the length of a parallel data connection that is usually shorter than a serial connection.
