Page 30 - The practical construction put upon a contract by the parties to it Is sometimes almost conclusive as to its meaning.
Page 112 - Fig. 22, but in many cases sufficiently accurate results can be obtained by cutting a beveled hole in the side of a tank. To give reliable results the orifice should be located a distance from the nearest side or the bottom of the tank not less than three times the width of the orifice. The tank or channel should also have a cross-section much larger than that of the orifice so Fig. 22. that the velocity of the water as it approaches the orifice will be small, otherwise the discharge will be affected...
Page 103 - a way to make, with one man and without fire, by means of machines, sheets of paper of very large size, even 12 feet wide and 50 feet long," and a patent was granted in 1800.
Page 113 - The term standard orifice is here used to signify that the opening is so arranged that the water in flowing from it touches only a line, as would be the case in a plate of no thickness. To secure this result the inner edge of the opening has a square corner, which alone is touched by the water. In precise experiments the orifice may be in a metallic plate whose thickness is really small, as at A in Fig.
Page 121 - Emerson, p. 101, also states that " The discharge of a turbine in proportion to its openings depends upon its construction. " With those of a central discharge it is the least; with such wheels of fair efficiency it is likely to range between 40 and 50 per cent; with outward discharge, 60 per cent and upwards; while with those discharging the water downward, it averages about 55 per cent. " The chutes of a curb are made much larger at their outer...
Page 31 - When the parties to a contract of doubtful meaning, guided by self-interest, enforce it for a long time by a consistent and uniform course of conduct, so as to give it a practical meaning, the courts will treat it as having that meaning, even if as an original proposition they might have given it a different one'
