APCI is a mode of ionization that is similar to ESI [electrospray ionization] in that ionization takes place at atmospheric pressure, entails nebulization and desolvation, and incorporates an interface design, which is similar to that of ESI. A key difference between APCI and ESI is that ESI is based on ions that are formed in solution, whereas APCI uses ions that are formed in the gas phase. In APCI, instead of high voltage being applied to the inlet capillary, mobile phase from the separation device is evaporated within a heater, and the vapor passes a needle with an applied current, which generates a corona discharge for the formation of stable reaction ions.  3, record 1, English, - atmospheric%20pressure%20chemical%20ionization

L'ionisation par APCI [...] se fait grâce à une décharge couronne. Ce type de décharge se forme lorsqu'on applique une haute tension sur une aiguille. Le champ électrique à la pointe de l'aiguille devient alors suffisamment intense qu'il se produit une décharge dans l'air, ionisant ses composantes. Ces ions peuvent ensuite réagir avec les molécules neutres de l'air pour former d'autres ions et même ioniser un analyte gazeux introduit près de la décharge couronne.  2, record 1, French, - ionisation%20chimique%20%C3%A0%20pression%20atmosph%C3%A9rique

Gas-fired water heaters have a gas burner located below the tank, a thermostatic switch, a gas valve and a pilot light. The thermostat will open the gas valve when it senses the water temperature at the bottom of the tank has dropped below the present limit. Gas flows to the burner and is ignited by the pilot light, heating the tank from below. In addition, the hot exhaust gases are vented through a hollow core in the center of the tank to help heat the water. The exhaust is then passed into the draft hood and to the vent connector where it is discharged to a chimney flue.  3, record 4, English, - gas%20water%20heater

The accumulator is intended for heating fuel components in the rocket and space engines and can be used in space engineering, aircraft and other branches of industry. The task of increasing gas heating efficiency, reducing mass of the construction, diminution of dimensions and lowering thermal and hydraulic losses of heated gas is solved by making a heat accumulating element as a mono-unit in the form of cylinder. The covers with branch pipes are recessed in the ends of the mono-unit. The covers are butt joined to mono-unit on conical surfaces through pressurizing end seals at forming the collectors for gas feed and discharge. Plate electric heater and channels or annular slot for flowing gas are located along the longitudinal axis. The axis of channels or annular slot location divides the mass of heat accumulating element into two equal parts. In so doing, porous insert or a set of badly stream-lined bodies is in the channels or annular slot.
