Reproducing. Producing again; copying; bringing forward or exhibiting again. .
Reproduction. (Fum.) A term referring to reproduced furniture, usually of the historic periods.
Reptile calf. (Leather.) A lizard grain produced on calfskin. It is mostly used for ladies purses, wallets, bill folds, etc.
Repulsion. (Elec.) The action of a force by which two similarly charged bodies tend to repel each other.
Repurcussion. The state of being driven back by a resisting body.
Replace. To provide a substitute or equivalent in the place of
Replenish. To make full or complete again.
Replica. Any close or exact copy or reproduction
Requistite. Required or necessary for a particular purpose.
Requisition. A formal request, as for supplies.
Research. Systematic inquiry into a subject in order to discover or revise facts, theories, etc.
Research chemical engineer. One whose work is along the line of examination and original investigation generally under the direction of the chief engineer.
Research engineer. One who engages in the investigation of mat~rials to increase the efficiency of the product. He also may investigate market conditions for the sales department or manufacturing conditions.
Reseat. (Auto.) To refinish a valve seat by means of a special reamer, by lapping process, or by specially mounted abrasive stones.
Residual magnetism. (Elec.) The small amount of magnetism left in a piece of iron afte.r the magnetizing force has been removed.
Residue. (Auto.) A sediment or deposit. That which remains after burning or pouring.
Resilience. . The act or power of springing back; capability of a
strained body to recover its size . and shape after deformation.
Resin. Any of various oily gummy substances obtained from certain trees, soluble in alcohol, ether, etc., but not in water.
Resinoid. (Plastics) A general term applied to synthetic-resinous substances as distinguished from natural resins.
Resistal. (Metal.) A very high grade of stainless steel. It is nonmagnetic and resists acid and rust.
Resistance. (Elec.) That property of a substance that opposes the flow
of an electric current through it. .
Resistancs box to Resonance radiation
Resistance box. (Elee.) A box containing known resistances, the amount of which can be varied by means of plugs or dials.
Resistance brazing. An electric brazing process wherein the heat is obtained from the resistance to the flow of an electric current.
Resistance butt welding. A group of resistance-welding processes wherein the fusion occurs over the entire cross-sectional area.
Resistance unit. (Auto.) A small coil of wire made of a metal highly resistant to the flow of electrons, or a small bat 'of carbon. (Both
. types are used interchangeably.) These units are introduced in certain aut~ electrical circuits to reduce the flow of electric current through the circuit.
Resistance welder. A resistance welding machine. (The term "welder" has sometimes been used to denote an operator of welding equipment for which the term "welding operator" is greatly to be preferred. )
Resistance welding. A pressure welding process wherein the heat is obtained from the resistance to the flow of an electirc current.
Resistance wire. (Elee.) Nickel-chromium electrical resistance wire sold under a number of trade names.
Resisting moment. (Engin.) The resistance to rotation by the moment of tensile and compressive stresses in that section which act as an internal couple.
Resisting shear. (Engin.) The internal opposing forces equal to the vertical shear of a section.
Resist printing. (Textile) A dyeing process in which portions of'the fabric are covered with dye-resistant paste.
Resolution. (TeL) Picture fidelity (better than 16 mm.).
Resolution of forces. (Phys.) The operation of finding two or more forces whose combined effect is equivalent to that of a given force.
Resolve. To separate and make visible the individual parts of an image.
Resonance. The state of a system in which an abnormally large vibration is produced in response to an external stimulus, occurring when the frequency of the stimulus is the same, or nearly the same, as a natural vibration frequency; the condition of a circuit with respect to a given frequency or the like in which the net reactance is a minimum and the current flow a maximum.
Resonance radiation. Radiation emitted by an atom or molecule, having the same frequency as that of an incident particle, as a photon, and involving a transition to
