Seite 498 - ... or it may perhaps extend also to a new process, to be carried on by known implements or elements, acting upon known substances, and ultimately producing some other known substance ; but producing it in a cheaper or more expeditious manner, or of a better and more useful kind. But no merely philosophical, or abstract principle, can answer to the word
Seite 497 - The declaration was hi the usual form, and the defendants pleaded thereto, first, that they were not guilty ; secondly, that the plaintiff was not the first and true inventor of the said...
Seite 499 - I will show you how the judges have heretofore allowed of monopoly patents, which is, that where any man by his own charge and industry or by his own wit or invention doth bring any new trade into the realm, or any engine tending to the furtherance of a trade that never was used before — and that for the good of the realm...
Seite 498 - There are numerous instances of patents which have been granted, where the invention consisted in no more than in the use of things already known, and acting with them in a manner already known, and producing effects already known ; but producing those effects so as to be more economically or beneficially enjoyed by the public.
Seite 13 - ... lie scattered for several hundred miles along the coast. The live oak is generally forty or fifty feet in height, and from one to two feet in diameter ; but it is sometimes much larger, and its trunk is often undivided for eighteen or twenty feet. There can be little doubt, from its great density and durability, that this is one of the finest species of oak that exists, surpassing even that for which Great Britain is so famous. Its cultivation has...
Seite 499 - ... blast and the bituminous coal ? and was the combination, described in the specification, new as to the public use thereof in England ? And, upon the first point, upon looking at the evidence in the cause, we think there is no doubt, that the result of the combination of the...
Seite 32 - Invention of Archimedes. — The Architonnerre is a machine of fine copper, which throws balls with a loud report and great force. It ii used in the following manner : — One-third of this instrument contains a large quantity of charcoal fire. When the water is well heated, a screw at the top of the vessel, which contains the water, mus.t be made quite tight. On closing the screw above, all the water will escape below, will descend into the heated portion of the instrument, and be immediately converted...
Seite 499 - ... the manufacture of the iron should be obtained at less expense. It was objected, in the course of the argument, that the quality or degree of invention was so small that it could not become the subject-matter of a patent; that a person who could procure a license to use the hot-air blast under Neilson's patent had a full right to apply that blast to coal of any nature whatever, whether bituminous or stone coal. But we think, if it were necessary to consider the...
Seite 499 - As to the first issue, namely, whether the defendants had infringed the patent, we think it clearly appears on the evidence, that the defendants had used, either in part or in whole, the combination described in the specification of the plaintiff's patent ; the plaintiff's evidence goes fully to show certain infringements, and that is not met by any explanation on the part of the defendants. Indeed, the defendants...
Seite 234 - The summary of their opinion is thus given: "1. That we consider the principle of Atmospheric propulsion to be established, and that the economy of working increases with the length and diameter of the tube. 2. That the expense of the formation of the line in cuttings, embankments, bridges, tunnels, and rails, will be very little less than for equal lengths of a Railway to be worked by locomotive engines ; but that the total cost of the...
