A type of electrolytic diaphragm cell for chlorine production, with graphite electrodes and a cylindrical shape.


Related Terms

PNEUMATIC CONTROL VALVE

A valve in which the force of compressed air against a diaphragm is opposed by the force of a spring to control the area of the opening for a fluid stream.

OPTICAL INDICATOR

An instrument which makes a plot of pressure in the cylinder of an engine as a function of piston (or volume) displacement, making use of magnification by optical systems and photographic recording; for example, the small motion of a pressure diaphragm may be transmitted to a mirror to deflect a beam of light.

NELSON DIAPHRAGM CELL

Obsolete carbon-electrode type of electrolytic diaphragm cell once widely used to produce chlorine and caustic soda from brine.

MAGNETIC MICROPHONE

[ENG ACOUS] A microphone consisting of a diaphragm acted upon by sound waves and connected to an armature which varies the reluctance in a magnetic field surrounded by a coil. Also known as reluctance microphone; variable-reluctance microphone.

HORIZONTAL PENDULUM

A pendulum that moves in a horizontal plane, such as a compass diaphragm and the air load.

HOOKER DIAPHRAGM CELL

A device used in industry for the electrolysis of brine (sodium chloride) to make chlorine and caustic soda (sodium hydroxide) or caustic potash (potassium hydroxide); saturated purified brine fed around the anode passes through the diaphragm to the cathode; chlorine is formed at the anode and hydrogen released at the cathode, leaving sodium hydroxide and residual sodium chloride in the cell liquor; the diaphragm prevents the products from mixing.

EXTERNAL EQUALIZER

Tube connected to low-pressure side of a thermostatic expansion valve diaphragm and to exit end of evaporator.

HORN

A sound signal which uses electricity or compressed air to vibrate a disc diaphragm.

TURBINE DIAPHRAGM

Partition between pressure stages in a turbine's casing. It holds the vane-shaped nozzles and seals between the stages. Usually labyrinth-type seals are used. One-half of the diaphragm is fitted into the top of the casing, the other half into the bottom.

KLAXON

A diaphragm horn similar to a nautophone, but smaller, and sometimes operated by hand
