Strona 323 - ... powerful effects ; for upon being brought into contact, a change was produced, at the distance of five feet, in the direction of compass needles. Steel bars enclosed in glass cylinders, with wire wound spirally round them, were rendered magnetic, and several of them suspended together. The electric intensity of the apparatus is very slight. A paper was read at the same meeting, on the condensation of several gases into liquids ; by Mr. Faraday, Chemical Assistant in the Royal Institution. In...
Strona 175 - I do hereby declare this to be my specification of the same, and that I do verily believe this my said specification doth comply in all...
Strona 221 - Boil one pound of good flour, a quarter of a pound of brown sugar, and a little salt, in two gallons of water for...
Strona 257 - ... to which the valve has been adjusted, but is superior to it, by which it is enabled to overpower the resistance of the weight t, and it carries the valve up with it, and closes the orifice r. This is no sooner done than the water is constrained to become stationary again, by which the momentum is lost, and the valve and weight once more become superior, and fall...
Strona 33 - Persons claiming any Right Title or Interest in Law or Equity of in or to the said Lease...
Strona 256 - The water-ram, or btller hydraulique, as it was called by its inventor, M. Montgolfier, of Paris, is a highly useful and simple machine, for the purpose of raising water, without the expenditure or aid of any other force than that which is produced by the momentum or moving force of a part of the water that is to be raised ; and is one of the most simple and truly philosophical machines that hydraulics can boast. The...
Strona 189 - Derbyshire, iron master; for an improved method of manufacturing cannon shot, by which a superior shot is produced in the solidity and smoothness of its external surface.
Strona 39 - ... express our admiration of the ingenuity and simplicity with which every part of the apparatus is constructed and arranged. We shall in our next describe the specification of this invention, and hope to be favoured with the practical remarks of the patentee.
Strona 48 - Howison is of a whitish colour, approaching to that of silver, and is very sonorous. When held in one hand, and struck with the fingers of the other, the sound is distinctly heard at the distance of an English mile. It is also highly polished, and does not seem to be easily tarnished. The piece that was sent me I found was malleable at a natural temperature, and at a red heat ; but when heated to whiteness, it was quite brittle...
Strona 258 - ... to move again ; and as the pressure of the water and the weight of the valve each become alternately superior, the valve is kept in a constant state of vibration, or of opening and shutting, without any external aid whatever. Such is the principle upon which the motion of the water in the pipe qq is produced ; but the momentum generated cannot be instantly annihilated, and it is not only of sufficient power to raise the valve s, but likewise to burst open the lower end of the pipe qq, unless...
