Mechanical Definitions
|
Electrolytic grinding : A combined grinding and machining
operation in which the abrasive, cathodic grinding wheel is
in contact with the anodic workpiece beneath the surface of
an electrolyte. |
Electromachining : It is an application of electric or
ultrasonic energy to a workpiece to effect the removal of material.
|
Electromagnetic clutch : A clutch which is based on magnetic
coupling between conductors, such as a magnetic fluid and power
clutch, an eddy-current clutch, or a hysteresis clutch. It is
angaged and disengaged by an electromagnetic actuator. |
Electromechanical : Pertaining to a mechanical device, system or process which is electrostatically or electromagnetically actuated or controlled.
|
Electromechanics : The technology of mechanical devices,
systems or processes which are electrostatically or electromagnetically
actuated or controlled. Electromechanics combines the sciences
of electromagnetism of electrical engineering and mechanics. |
Electronic flame safeguard : It is an electrode which
is used in a burner system that detects the main burner flame
and interrupts fuel flow if the flame is not detected. |
Electronic humidistat : A humidistat in which a change in the relative humidity causes a change in the electrical resistance between two sets of alternate metal conductors mounted on a small flat plate with plastic coating, and this change in resistance is measured by a relay amplifier.
|
Electronic thermometer : In electronic thermometer a
sensor (usually a thermistor) is placed near or on the object
being measured. |
Electrostatic separator : It is a device for separating
particles by mass in a low energy charged beam. In this finely
pulverized mixture falls through a powerful electric field between
two electrodes; material shaving different specific inductive
capacitances are deflected by varying amounts and fall into
different sorting chutes. |
Elevator dredge : It is a dredge which has a chain of
buckets, usually flattened across the front and mounted on a
nearly vertical ladder. It is used principally for excavation
of sand and gravel beds under bodies of water. |
Elliptic gear : It is a change gear made of two elliptically
shaped gears, each rotating about one of its focal points. |
