Vocabulary : Manograph to Manqueller
Manograph : An optical device for making an indicator diagram for high-speed engines. It consists of a light-tight box or camera having at one end a small convex mirror which reflects a beam of light on to the ground glass or photographic plate at the other end. The mirror is pivoted so that it can be moved in one direction by a small plunger operated by an elastic metal diaphragm which closes a tube connected with the engine cylinder. It is also moved at right angles to this direction by a reducing motion, called a reproducer, so as to copy accurately on a smaller scale the motion of the engine piston. The resultant of these two movements imparts to the reflected beam of light a motion similar to that of the pencil of the ordinary indicator, and this can be traced on the sheet of ground glass, or photographed.Manometer : An instrument for measuring the tension or elastic force of gases, steam, etc., constructed usually on the principle of allowing the gas to exert its elastic force in raising a column of mercury in an open tube, or in compressing a portion of air or other gas in a closed tube with mercury or other liquid intervening, or in bending a metallic or other spring so as to set in motion an index; a pressure gauge. See Pressure, and Illust. of Air pump.
Manometric : Alt. of Manometrical
Manometrical : Of or pertaining to the manometer; made by the manometer.
Manor : The land belonging to a lord or nobleman, or so much land as a lord or great personage kept in his own hands, for the use and subsistence of his family. ;; A tract of land occupied by tenants who pay a free-farm rent to the proprietor, sometimes in kind, and sometimes by performing certain stipulated services.
