	Sluice - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-11-05)
		A sluice gate is traditionally a wooden or metal plate which slides in grooves in the sides of the channel.
		Sluice gates are commonly used to control water levels and flow rates in rivers and canals.
		needle sluice - a sluice formed by a number of thin needles held against a solid frame through water pressure as in a needle dam.

	SLUICE - Definition
		An artifical passage for water, fitted with a valve or gate, as in a mill stream, for stopping or regulating the flow; also, a water gate or flood gate.
		{Sluice gate}, the sliding gate of a sluice.
		To wash with, or in, a stream of water running through a sluice; as, to sluice eart or gold dust in mining.

	Intro to Power Sluicing
		Power Sluice machines can be used at the waters edge to process gravel from a stream bank, used as portable dredge, or taken to remote areas from the waters edge where gold often occurs in greater abundance.
		The sluice has a fl rubber ribbed material that is placed below the hopper to preserve the sluice from impact and for quick identification of the occurrence of gold and values.
		The sluice box often is lined with "miners moss" a material that holds the gold in the separation process for improved recovery.

	The Lock and Sluice and the fishing harbour
		The sluice is well hidden under the road leading across the channel, but the lock is highly visible thanks to the bascule bridge and the large blue harbour administration tower, Blåtårn.
		The dam with lock and sluice was built in 1928-31 and provided the basis for the development of the harbour and Hvide Sande township.
		The purpose of the sluice was thus to control water levels and salt content in the fjord.

	Sluice box classifier for gold mining dredge (US4472269)
		A sluice box classifier for a sluice box of a gold mining dredge includes a trough and a rim secured to an underside of the trough.
		The trough is formed of four walls and a bottom, and is at least as wide as a lower end portion of the sluice box from which collected overburden is received.
		The floor panels funnel overburden deposited into the trough from the sluice box to the center panel where a plurality of openings in the center panel allows the smaller pieces of overburden to pass through into the container.

	Sluicing Instructions
		If the sluice box is somewhat unstable in the current, position a few rocks around the outside of the trough to brace it.
		Each time a new load of gravel is dumped into a sluice box with overloaded riffles, any gold in that gravel will wash right over the material that is clogging your riffles and out the discharge end of the box.
		After dumping each load of gravel into the sluice box, check the riffle section for large waste rocks that may be lodged in the sluice.

		Jacob van Ruisdael, one of the great Dutch landscape painters of the 1600s, explored a wide range of landscape motifs in his work, including forest scenes, seascapes, beach scenes, and panoramic landscapes.
		In The Sluice, Ruisdael made an ordinary object monumental by making it larger than all the other elements in the painting, thereby calling attention to its use and placement in the countryside.
		A single figure populates the scene, but the sluice symbolizes the human presence in nature and human attempts to control it.

		The shorter the sluice the smaller the grade should be, as there is more danger or fine gold being lost in a short than in a long sluice.
		When the incline of a sluice is slight gold is easily caught, and much of it will be caught on the smooth floor of the sluice without the aid of riffle-bars.
		In California false bottoms are made of riffle-bars, which run lengthwise with the sluice about 5 feet long, 3 to 7 inches wide and 2 to 4 inches thick; 2 sets for each length of sluice.

		A portion of the mountain in the Sitio B'langas was cut almost in half due to sluice mining operations.
		Sluice mining is a method where miners move the soil for easier extraction of the gold particles.
		These sluice boxes have screens that are used to separate the fine gold particles from the ore. The miners then gather the accumulated gold particles, place them in a container and pan them using mercury.

		Water, the basic source of life for mankind since the very beginning, has become a precious commodity in modern society as well as in the developing nations of the world.
		The self-adjusting feature is obtained by a continuous compression cord that ensures a tight seal between the slide and the frame in both seating and unseating conditions.
		The continuous wedging action of the compression cord on the slide enables the SERIES 20 sluice gate to control flow by allowing water only through the open portion of the gate.

	Seaton Sluice Northumberlands Coal Export Docks - NORTH COUNTRY WEB
		With the increase in trade over the years at Seaton Sluice plans were drawn up in 1690 for a new harbour or dock when the old basin was becoming inadequate to cope with the trade of the port.
		The coal trade of Seaton Sluice was ruined by the appalling catastrophe at Hartley New Pit, on January 16, 1862, when 204 men and boys lost their lives when a support beam for a pumping engine cracked and fell down the shaft, imprisoning them in the mine without a hope of escape.
		New Hartley village lies a mile inland from Seaton Sluice, and about a mile to the north east of Seaton Delaval was originally part of the parish of Earsdon, which Charlie Steel explained elsewhere was a northern suburb of Monkseaton and Whitley Bay

	Pinched Sluice (Site not responding. Last check: 2007-11-05)
		If the pinched sluice has laminar flow, the layers become well defined, with virtually all the heavy minerals on the bottom.
		When such a sluice is narrowed or "pinched" at the downstream end, the depth of the flow is increased making the layers easier to separate into concentrate and tailings.
		The pinched sluice must be operated with an even, dense feed.

	Sluice Gates (Penstocks / Slide gates)
		Wall-mounted sluice gates (occasionally referred to as penstocks or slide gates) are used to close off an opening in a wall, often between adjacent tanks or chambers, as well as outlets in dam walls.
		The most common type of seals used on sluice gates are Neoprene "music note" or "J" seals, and as it is not possible to utilise these seals on circular gates, all our sluice gates have square or rectangular openings.
		Water pressure forces the bulb of the seal against the sealing surface on the frame of the penstock, and the higher the pressure, the greater the force.

	Sedgemoor District Council - Sluice Boost from new partnership (Site not responding. Last check: 2007-11-05)
		A partnership of organisations dedicated to developing and championing the proposal to build a tidal sluice on the River Parrett near Bridgwater to reduce the risk of flooding and pave the way for economic regeneration met in Bridgwater on Friday (May 7).
		Symonds told the meeting that the sluice would help safeguard the 11,000 properties which are at risk in Bridgwater and the surrounding villages from a one in 200 year tidal flood.
		It is estimated that it would cost between £20 and £40 million, but that compares favourably with the estimated cost of the main alternative option for flood defence, which would be to raise the flood banks on either side of the river.

		Indian Sluice is the channel between Sluice Point and Surette's Island over which was installed a bridge in 1909.
		The tides along the shores of Yarmouth County rise very high; when the rising water reaches the sluice, it rushes through it, towards the many inland bodies of water, with an enormous force of six or seven miles an hour.
		To avoid the sluice, people at times would make a detour, although the sluice could be easily crossed at high tide or low tide.

		If the dynamics and timing of the discharge from sluice gates controlling water in modified / compartmentalized floodplain are understood, then the regime of operation of gates for mutual benefits of fish and rice could be devised.
		But the information/ data on the dynamics of the discharge from sluice gates and the migration behaviour of fish are not available in the country.
		The goal and objective of the projects are to optimize the use of sluice gates through developing a protocol for the operation of sluice gates to give improved integration of water control for natural fish enhancement with rice farming in empoldered flood plain to benefit the poor fishing and farming community.

	Sluice Your Way to Success (Site not responding. Last check: 2007-11-05)
		"Sluicing"-a gold mining technique that's been around since about the sixteenth century-can greatly increase the amount of gravel a panner can work.
		You can construct or buy sluices of varying degrees of complexity, but the small, oldfashioned variety made of wood or metal-which lies in the stream and uses the natural flow of water-is quite effective...
		A wooden sluice, however, usually weighs at least 30 pounds when dry (and-of course-a lot more once it's waterlogged!).
