Page 142 - The unit of quantity shall be what is known as the international coulomb, which is the quantity of electricity transferred by a current of one international ampere in one second. Fifth. The unit of capacity shall be what is known as the international farad, which is the capacity of a condenser charged to a potential of one international volt by one international coulomb of electricity.
Page 60 - The law does not require that a discoverer or inventor in order to get a patent for a process must have succeeded in bringing his art to the highest degree of perfection. It is enough if he describes his method with suflkieut clearness and precision to enable those skilled in the matter to understand what the process is, and if he points out some practicable way of putting it into operation.
Page 48 - We think it proper to reiterate our disapprobation of these ingenious attempts to expand a simple invention of a distinct device into an all-embracing claim, calculated by its wide generalizations and ambiguous language to discourage further invention in the same department of industry and to cover antecedent inventions.
Page 46 - The method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sounds.
Page 142 - As a unit of current, the international ampere, which is onetenth of the unit of current of the cgs system of electromagnetic units, and which is represented sufficiently well for practical use by the unvarying current which, when passed through a solution of nitrate of silver in water, and in accordance with accompanying specifications, deposits silver at the rate of 0.001118 of a gramme per second.
Page 142 - As a unit of electromotive force, the international volt, which is the electromotive force that, steadily applied to a conductor whose resistance is one international ohm, will produce a current of one international ampere, and which is represented sufficiently well for practical use by ^2.
Page 372 - ... volume that, owing to the conductive properties of the earth, it will be conveyed upon the grounds of his neighbor with such force and to such an extent as to break up his business or impair the value of his property, and not be held responsible for the resulting injury.
Page 142 - As a unit of resistance, the international ohm, which is based upon the ohm equal to 10" units of resistance of the CGS system of electromagnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice, 14.4521 grams in mass, of a constant cross-sectional area and of the length of 106.3 centimetres.
Page 142 - As a unit of work, the joule, which is equal to 107 units of work in the CGS system, and which is represented sufficiently well for practical use by the energy expended in one second by an international ampere in an international ohm. As a unit of power, the watt, which is equal to 10...
Page 372 - ... but such authority carries with it no lawful right to do an act which would be a trespass, if done by a private person conducting a like business. If either collects for pleasure or profit the subtle and imperceptible electric fluid, there would seem to be no great hardship in imposing upon it, or him, the same duty which is exacted of the owner of the accumulated water power; that of providing an artificial conduit for the artificial product, if necessary to prevent injury to others.
