lly, porous infusorial earth, used as an absorbent of nitroglycerin in the manufacture of dynamite.

See Dynamics.

Any one of several species of cuckoos of the genus Eudynamys, found in India, the East Indies, and Australia. They deposit their eggs in the nests of other birds.

he action of magnets; as, magneto-electric induction. Magneto-electric machine, a form of dynamo-electric machine in which the field is maintained by permanent steel magnets instead of electro-magnets.

One of successive or homodynamous parts in animals and plants; one of a series of similar parts that follow one another in a vertebrate or articulate animal, as in an earthworm; a segment; a somite. See Illust. of Loeven's larva.

A suffix denoting that by which anything is measured; as, barometer, chronometer, dynamometer.

s of humanity, established by the will of A. B. Nobel (1833- 96), the Swedish inventor of dynamite, who left his entire estate for this purpose. They are awarded yearly for what is regarded as the most important work during the year in physics, chemistry, medicine or physiology, idealistic literature, and service in th…

A dynamometer for measuring the force required to draw wheel carriages on roads of different constructions. G. Francis.

A small incandescent telltale lamp on a dynamo or battery circuit to show approximately by its brightness the voltage of the current.

A dynamometer for ascertaining the power required to draw carriages over roads.

cess of high milling for grinding flour. See under Milling. -- Reversible process (Thermodynamics), any process consisting of a cycle of operations such that the different operations of the cycle can be performed in reverse order with a reversal of their effects.

Specifically, the reaction or rebounding of a firearm when discharged. Recoil dynamometer (Gunnery), an instrument for measuring the force of the recoil of a firearm. -- Recoil escapement See the Note under Escapement.

A kind of dynamite used in blasting. [U.S.]

An armature for a dynamo or motor having the conductors wound on a ring.

r of gamopetalous plants (Scrophulariaceæ, or Scrophularineæ), usually having irregular didynamous flowers and a two-celled pod. The order includes the mullein, foxglove, snapdragon, figwort, painted cup, yellow rattle, and some exotic trees, as the Paulownia.

To energize or excite (the field magnets of a dynamo) by induction from the residual magnetism of its cores, leading all or a part of the current thus produced through the field-magnet coils.

To join, as the electrodes of a battery or dynamo or any two points of a circuit, by a conductor of low resistance.

nducting circuit joining two points in a conductor, or the terminals of a galvanometer or dynamo, so as to form a parallel or derived circuit through which a portion of the current may pass, for the purpose of regulating the amount passing in the main circuit.

An electrodynamic spiral having the conjuctive wire turned back along its axis, so as to neutralize that component of the effect of the current which is due to the length of the spiral, and reduce the whole effect to that of a series of equal and parallel circular currents. When traversed by a current the solenoid exhi…
