Seite 54 - Blasco de Garay, a sea cap. tain, exhibited to the emperor and king Charles V., in the year 1543, an engine by which ships and vessels of the largest size could be propelled, even in a calm, without the aid of oars or sails. Notwithstanding the opposition which this project encountered, the emperor resolved that an experiment should be made, as in fact it was, with success, in the harbor of Barcelona, on the 17th of June, 1543. Garay never publicly exposed the construction of his engine, but it was...
Seite 60 - Middlesex, merchant, in consequence of a communication made to him by a certain foreigner residing abroad...
Seite 10 - Prints, shall have the sole Right and Liberty of printing and reprinting the same for the Term of Fourteen Years, to commence from the Day of the first publishing thereof, which shall be truly engraved with the Name of the Proprietor on each Plate, and printed on every such Print or Prints...
Seite 171 - Mr Dalton's permanent reputation will rest upon his having discovered a simple principle universally applicable to the facts of chemistry, in fixing the proportions in which bodies combine, and thus laying the foundation for future labours respecting the sublime and transcendental parts of the science of corpuscular motion. His merits in this respect resemble those of Kepler in astronomy.
Seite 60 - London, merchant, in consequence of a communication made to him by a certain foreigner residing abroad, for an invention of " certain improvements in boilers for generating steam.
Seite 55 - Colibre to discharge a cargo of wheat at Barcelona; it was called the Trinity, and the captain's name was Peter de Scarza.
Seite 41 - Where the moulds are not used soon after being made, treacle should be previously mixed with the glue (as employed by printers), to prevent it becoming hard. The description thus given is with reference to moulding those bodies which cannot be so done by any other than an elastic mould : but glue moulds will be found greatly to facilitate casting in many departments, as a mould may frequently be taken by this method in two or three pieces, which would on any other principle require many. DOUGLAS...
Seite 104 - THE usual mode of ornamenting ivory in black, is to engrave the pattern or design, and then to fill up the cavities thus produced with hard black varnish. The demand for engraved ivory in ornamental inlaying, and for other purposes, is considerable, although the price paid for it is not such as to encourage artists of much ability to devote themselves to this work, which consequently is trivial in design and coarse in execution. Mr Cathery's improvement consists in covering the ivory with...
Seite 152 - ... range. If the engine should be worked by a connecting rod, as is sometimes the case in steam-boats, say only one diameter of the path of the crank, the variation at each end of the stroke would amount to a practical defect, since the piston would move with nearly three times the velocity at the lowest quarter of the stroke that 'it would at the first quarter. Thus circumstanced, the crank must be above the cylinder. As the law of expansion seems not yet to be settled, an arithmetical expansion...
Seite 55 - Notwithstanding the difficulties and opposition thrown in the way by Ravago, the invention was approved, and if the expedition, in which Charles the Fifth was then engaged, had not failed, it would undoubtedly have been favored by him. As it was, he raised Garay to a higher station, gave him a sum of money (200,000 maravedies) as a present, ordered all the expenses of the experiment to be paid out of the general treasury, and conferred upon him other rewards.
