PLATE CONVEYOR

A conveyor with a series of steel plates as the carrying medium; each plate is a short trough, all slightly overlapped to form an articulated band, and attached to one center chain or to two side chains; the chains join rollers running on an angle-iron framework and transmit the drive from the driveheads, installed at intermediate points and sometimes also at the head or tail ends.

PLATEN

1.A flat plate against which something rests or is pressed. 2. The rubber-covered roller of a typewriter against which paper is pressed when struck by the typebars. 2. A flat surface for exchanging heat in a boiler or heat exchanger which may have extended heat transfer surfaces.

PLATE GIRDER BRIDGE

A fixed bridge consisting, in its simplest form, of two flange plates welded to a web plate in the overall shape of an I.

PLATE GIRDER

A riveted or welded steel girder having a deep vertical web plate with a pair of angles along each edge to act as compression and tension flanges.

PLATE EFFICIENCY

The equilibrium produced by an actual plate of a distillation column or countercurrent tower extractor compared with that of a perfect plate, expressed as a ratio.

PLATE

1. A shoe or base member, such as of a partition or other kind of frame. 2. The top horizontal member of a row of studs used in a frame wall. 3. A rolled, flat piece of metal of some arbitrary minimum thickness and width depending on the type of metal. 4. One of the conducting surfaces in a capacitor. 5. One of the electrodes in a storage battery.

PERFORATED-PLATE DISTRIBUTOR

1. A perforated plate or screen used to even out liquid-flow fluctuations through flow channels. 2. A perforated plate as used in a distillation column or liquid-liquid extraction column.

PENDULUM ANEMOMETER

A pressure-plate anemometer consisting of a plate which is free to swing about a horizontal axis in its own plane above its center of gravity; the angular deflection of the plate is a function of the wind speed; this instrument is not used for station measurements because of the false reading which results when the frequency of the wind gusts and the natural frequency of the swinging plate coincide.

PARALLELS

1. Spacers located between steam plate and press platen of the mold to prevent bending of the middle section. 2. Spacers or pressure pods located between steam plates of a mold to regulate height and prevent crushing of mold parts.

OUTPUT-METER ADAPTER

Device that can be slipped over the plate prong of the output tube 385 output-meter adapter output power of a radio receiver to provide a conventional terminal to which an output meter can be connected during alignment.
