Romanization of Greek Greek numerals which employed the entire alphabet, including the nonstandard letters digamma, stigma, or sigma-tau (placed between epsilon and zeta), koppa (placed between pi and rho), and sampi (placed after omega). As revised in 2001, ELOT 743 provides for the uncommon characters to be given (in Greek) as $ for stigma, + for koppa, and / for sampi. These symbols are not given lower-case equivalents. When used as numbers, the letters are used in combination with the upper "keraia" numeral sign ⟨ʹ⟩ to denote numbers from 1 to 900 and in combination with the lower "keraia" ⟨͵⟩ to denote multiples
Torque limiter the reel will turn and allow more line to unwind before the line breaks under the pull of a fish. A magnetic particle clutch can be used effectively as a torque limiter. The torque setting fairly approximates a linear relationship with the current passing through the windings, which can be statically or dynamically set depending on needs. This type is non-synchronous in normal operation, so there is always some slippage. Torque limiter A torque limiter is an automatic device that protects mechanical equipment, or its work, from damage by mechanical overload. A torque limiter may limit the torque by slipping
