Operation. The solvent is heated to reflux. The solvent vapour travels up a distillation arm, and floods into the chamber housing the thimble of solid. The condenser ensures that any solvent vapour cools, and drips back down into the chamber housing the solid material.

It works like this: You clamp the pocket hole jig onto your workpiece and drill angled holes with the special stepped drill bit. Then you simply align the two pieces to be joined and drive a pocket screw at an angle into the pocket to connect your pieces.

How An XLR Cable Works. When two balanced devices are connected, the XLR cable delivers a positive audio signal, a negative audio signal and a ground signal. ... However, the noise that was on the audio signal has now been inverted. When the inverted noise is combined with the original noise, they cancel each other out.

Smoke and Spatter are reduced when pipe joints are welded by means of the Surface Tension Transfer (STT®) process. In open root pass pipe welding, the STT process controls the wave form of the welidng current for excellent penetration control, fusion, and back bead.

On some racing wheels, they use two valve stems so you can inflate/deflate the tire while a pressure gauge is connected to the second valve stem. So it could be for that.

['Next, the wet cornmeal loads into an extruding machine that forms the shape of the collette (corn puff).', 'An auger pushes the mixture through a die as it is exposed to high pressure.']

How a VSI Crusher Works. Feed material drops through the feed tube onto the impeller table or enclosed rotor which, through centrifugal force, throws the material against stationary anvils made up of composite metal alloys. ... This method of crushing is simple and economical to operate.

How does an electronic handbrake work? The traditional handbrake lever tensions a cable when it's pulled up. That cable squeezes the car's rear brake pads or shoes onto the brake discs – or drums – holding the car firmly in place. ... Press or pull the button and motors on the rear brakes press the pads onto the discs.

So the engineers at the pivot companies figured out how to bring the power up into a device called a collector ring. The power from the pivot point is distributed to a series of stationary circular plates and then connections are made to the wires that travel down the pivot's pipe spans. Keeping the pipes from rusting.

Soxhlet extraction. Definition: The process of transferring the partially soluble components of a solid to the liquid phase using a Soxhlet extractor. ... The solvent (heated to reflux) travels into the main chamber and the partially soluble components are slowly tranferred to the solvent.

How does the swivel mechanism on an office chair work? ... If the chair is too low, a lever releases the friction clamp, letting the piston come up, raising the chair against the chair's weight. If a person is sitting in the chair at that time, the gas pressure against the piston is not enough, and the chair goes down.

It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent.

Pump jacks operate on the same basic principle of some hand pumped water wells that some people are familiar with. ... As the system moves up and rod, the sucker rod pump works somewhat like a piston - increasing pressure within the well - and lifts the oil from the reservoir to the surface.

A Soxhlet extractor has three main sections: a percolator (boiler and reflux) which circulates the solvent, a thimble (usually made of thick filter paper) which retains the solid to be extracted, and a siphon mechanism, which periodically empties the thimble.

the ball joint is design to spin freely with out load....that is how the press them into the knuckle assem. the trick to get them to not to spin is to apply a load on them.... this mean you jack up the suspension alittle bit until they no longer spin. warning don't jack on the ball joint stud, you will damage it.

It works in a network form. The body directs pressurized transmission fluid to a network of valves that put together appropriate clutch packs for smooth gear functioning. Further, the valves use the pressure of hydraulic signals, determining the gear set, also known as servo.

In a string pinsetter there is a string attached to the top of the pin. The string is said to have no interference with the pins when the ball hits them. At the end of each throw, the machine pulls the pins back into a rack and resets the pins that weren't knocked down.
