Indicator :: Indicator (n.) An instrument which draws a diagram showing the varying pressure in the cylinder of an engine or pump at every point of the stroke. It consists of a small cylinder communicating with the engine cylinder and fitted with a piston which the varying pressure drives upward more or less against the resistance of a spring. A lever imparts motion to a pencil which traces the diagram on a card wrapped around a vertical drum which is turned back and forth by a string connected with the pist

Tasimer :: Tasimer (n.) An instrument for detecting or measuring minute extension or movements of solid bodies. It consists essentially of a small rod, disk, or button of carbon, forming part of an electrical circuit, the resistance of which, being varied by the changes of pressure produced by the movements of the object to be measured, causes variations in the strength of the current, which variations are indicated by a sensitive galvanometer. It is also used for measuring minute changes of temperature..

Embrace :: Embrace (n.) Intimate or close encircling with the arms; pressure to the bosom; clasp; hug.

Portative :: Portative (a.) Capable of holding up or carrying; as, the portative force of a magnet, of atmospheric pressure, or of capillarity..
