* Open circuit demand scuba exhausts exhaled air to the environment, and requires each breath to be delivered to the diver on demand by a diving regulator, which reduces the pressure from the storage cylinder and supplies it through the demand valve when the diver reduces the pressure in the demand valve slightly during inhalation.

Open circuit demand scuba exhausts exhaled air to the environment, and requires each breath to be delivered to the diver on demand by a diving regulator, which reduces the pressure from the storage cylinder and supplies it through the demand valve when the diver reduces the pressure in the demand valve slightly during inhalation.

The regulator also greatly reduces the ripple and noise in the output direct current.

A diving regulator is a pressure regulator used in scuba or surface supplied diving equipment that reduces pressurized breathing gas to ambient pressure and delivers it to the diver.

A gas pressure regulator has one or more valves in series, which reduces pressure from the source in a controlled manner, lowering pressure at each stage.

The terms " regulator " and " demand valve " are often used interchangeably, but a demand valve is the part of a regulator that delivers gas only while the diver is breathing in and reduces the gas pressure to ambient.

The high frequency allows the transformer to be small, which reduces its losses ; and the switching regulator can be much more efficient than a linear regulator.

To ensure that the amount of capital outstanding doesn't fall sharply once a Lower Tier 2 issue matures and, for example, not be replaced, the regulator demands that the amount that is qualifiable as Tier 2 capital amortises ( i. e. reduces ) on a straight line basis from maturity minus 5 years ( e. g. a 1bn issue would only count as worth 800m in capital 4years before maturity ).

The argon flow from commercial bottles was regulated by a pressure regulator and measured with a gas flow rator.

* a regulator mechanism to control gas flow and pressure, ( two may be used for redundancy ),

This type of set consists of one or more diving cylinders containing breathing gas at high pressure, typically, connected to a diving regulator.

The regulator supplies the diver with as much of the gas as needed, at a pressure suitable for breathing at the depth of the diver.

On the high pressure side of the compressor a regulator is used to reduce pressure of a sample flow and the trimix is analyzed ( preferably for both helium and oxygen ) so that the fine adjustment to the intake gas flows can be made.

A back-pressure regulator is a variation of a valve in which flow is controlled to maintain a certain upstream pressure, if possible.

A pressure cooker: the regulator is a weight on a nozzle next to the handle on the lid

* Steam vent with a pressure regulator on top ( either a weight or spring device ) which maintains the pressure level in the pan

This is typically done by having different regulator weights or different pressure settings.

In other models, the pressure regulator weight begins levitating above its nozzle, allowing excess steam to escape.

For first generation pressure cookers with a weighted valve or " jiggler ", the primary safety valve or regulator is usually a weighted stopper, commonly called " the rocker " or " vent weight ".

It delivered air at constant pressure without a demand regulator.

The demand-valve, or regulator, was designed for regulating gas in gas-generator engines, but was found to be excellent for regulating air-supply under varied pressure conditions.

Like modern open-circuit scuba with single-hose regulators, they consisted of one or more high pressure diving cylinders and a diving regulator ( the Aqua-Lung ) that supplied the diver with breathing gas at ambient pressure via a demand valve.

The response regulator Protein-glutamate methylesterase | CheB takes the phosphoryl group from CheA.

Hayek claimed that " the past instability of the market economy is the consequence of the exclusion of the most important regulator of the market mechanism, money, from itself being regulated by the market process.

Regulation: The National Communications Authority ( NCA ), an independent regulator, was created in 1997, deriving its statutory framework from the NCA Act 1996.

The export-orientated approach has encouraged liberalisation supported by strong state involvement as a facilitator ( of the enabling environment for the private sector ); as operator ( to encourage competition ); and as regulator ( to protect the economy as well as vulnerable groups and sectors from shocks ).

Lambertsen's invention ( patented by himself several times from 1940 to 1989 ) was a rebreather and is different from the open circuit diving regulator and diving cylinder assemblies also commonly referred to as scuba.

The Rouquayrol-Denayrouze apparatus was the first regulator to be Mass production | mass produced ( from 1865 to 1965 ).

After having travelled to England and discovered William James ' invention, the French physician Manuel Théodore Guillaumet, from Argentan ( Normandy ), patented in 1838 the oldest known regulator mechanism.

A more successful and safer regulator was mass produced in France from 1865 to 1965 ( although production was twice interrupted during that period ): invented by Benoît Rouquayrol in 1860 for survival in flooded mines it was adapted to diving in 1864 with the help of French Navy officer Auguste Denayrouze.

From 1934 to 1944 the Commeinhes family ( René and his son Georges ) from Alsace invented and successfully tested a demand regulator, but the main inventor, Georges, was killed in 1944 during the liberation of Strasbourg and Cousteau's regulator had no competitors immediately after the war.

After World War II, military frogmen of all countries continued to use rebreathers ( since they do not make bubbles and thus are not visible from the surface ) and Air Liquide started selling commercially the Cousteau-Gagnan regulator as of 1946 under the name of scaphandre Cousteau-Gagnan or CG45 (" C " for Cousteau, " G " for Gagnan and 45 for a new 1945 patent ).

An extra feed from the first-stage regulator lets the lifejacket be controlled as a buoyancy aid.

Eventually, the federal regulator enacted the Prime Time Access Rule, which restricted the amount of time that the networks could air programs ; officials hoped the rules would foster the development of quality local programs, but in practice, most local stations did not want to bear the burden of producing many of their own programs, and instead chose to purchase programs from independent producers.

This set was stated to be made from " off-the-shelf " items, which shows that MSA had that regulator design before ; also, that regulator looks like the result of development and not a prototype ; it may have arisen around 1943.

On 11 December 2009 Egypt's regulator approved an offer from a unit of France Telecom ( Orange ) to buy Mobinil.

First conceived as a device to help assist in escaping from flooded mines, the Rouquayrol regulator was adapted to diving in 1864, when Rouquayrol met the lieutenant de vaisseau Auguste Denayrouze.

Modern single-hose regulators derive from the design of Australian Ted Eldred, who developed the " Porpoise " regulator in Melbourne in 1949.

Baritone: A, G, F #, D. Bass: C, B, A, G. The tenor and baritone regulators fit into the front face of the stock, on top of the drones ; the bass regulator is attached to the side of the stock ( furthest from the piper ), and is of complex construction.

This is when a regulator is absent from the binding site.

The first diving equipment that combined a high-pressure cylinder and a breathing device ( although not a demand regulator as was the Rouquayrol-Denayrouze apparatus ) was invented separately by the Japanese Ohgushi in 1918 and the Frenchmen Maurice Fernez and Yves le Prieur in 1926.

Fernez had previously invented the noseclip, a mouthpiece ( equipped with a one-way valve for exhalation ) and diving goggles, and Yves le Prieur just joined to those three Fernez elements a hand-controlled regulator and a compressed-air cylinder.

Technical drawing of a Mistral ( regulator ) | Mistral Cousteau-type regulator ( model of 1955 ) mounted on a diving cylinder.

The rear of the regulator is connected to the high-pressure valve of the cylinder. 1.

Both men met in Paris in December 1942 and adapted Gagnan's regulator to a diving cylinder.

In this type of set, the two ( or occasionally one or three ) stages of the regulator are in a large circular valve assembly mounted on top of the cylinder pack.

There have been many incorrect depictions in comics of two-cylinder twin-hose aqualungs, showing one wide breathing tube coming directly out of each cylinder top with no regulator: see Diving regulator # Twin-hose without visible regulator valve ( fictional ).

A single-hose regulator with 2nd stage, gauges, BC attachment, and dry suit hose mounted on a cylinder

Modern recreational rigs most often have two regulators connected to a single cylinder, in case the primary regulator fails or another diver runs out of air.

Some divers instead connect their backup regulator to a smaller " pony cylinder " for extra safety, and there are also emergency systems which mount a simple regulator directly to the top of a small cylinder.

Both men meet then in Paris in December 1942 and adapt Gagnan's regulator to a diving cylinder.

MSA provided a small open-circuit breathing set with a small ( 5 to 7 liters ) air cylinder, a circular demand regulator with a two-lever system similar to Cousteau's design ( connected to the cylinder by a nut and cone nipple connection ), and one corrugated wide breathing tube connected to a mouthpiece.

When the regulator valve V was opened, steam was let out of the boiler filling the space in the cylinder beneath the piston.

The regulator valve was then closed and the water injection valve V ' briefly snapped open and shut sending a spray of cold water into the cylinder.
