The winding knob is on the side of the spool. Most reels are laid out for holding in the left hand and winding with the right. The knob is usually attached by a bolt which allows it to rotate, giving a more secure grip to the winding hand. [4] The line guide is a slotted attachment which guides the line onto the spool.
The uni knot is widely used for attaching hooks, rings and swivels to the end of the line [7] and it is also used for joining two fishing lines together. [8] The bend form of the uni knot (for joining two lines) is not a noose; rather it is akin to a multiple fisherman's knot with the two opposing knotted parts arranged in the manner of uni knots.
A reel is a tool used to store elongated and flexible objects (e.g. yarns/cords, ribbons, cables, hoses, etc.) by wrapping the material around a cylindrical core known as a spool. Many reels also have flanges (known as the rims ) around the ends of the spool to help retain the wrapped material and prevent unwanted slippage off the ends.
A magnetic flow meter (mag meter, electromagnetic flow meter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines.
Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...
A spoolbase is a shore-based facility used to facilitate continuous pipe laying for offshore oil and gas production. [1] The facility allows the welding of single or double joints (40' or 80') of steel pipe of 4" to 18" diameter, into predetermined lengths for spooling onto a reel lay vessel.
Backing is the rearmost section of the fishing line and typically used only to "pad up" the spool of the fishing reel, in order to prevent unwanted slippage between the mainline and the (usually metallic and well polished) spool surface, increase the effective radius of the spooled line and hence the retrieval speed (i.e. inches per turn), and ...
SPFM – single-phase flow meter; SPH – SPH log [clarification needed] SPHL – self-propelled hyperbaric lifeboats; SPM – side pocket mandrel; SPM – strokes per minute (of a positive-displacement pump [citation needed]) spm – shots per meter (perforation density [citation needed]) SPMT – self-propelled modular transporter
