Excerpt from The Register of Arts, and Journal of Patent Inventions, 1831, Vol. 5 As the water evaporates, the salt is deposited on the bottom of the evaporating vessel, and is removed therefrom by scrapers in the usual manner. The principle advantage of this arrangement, is the entire removal from the fire of the surface on which the salt is deposited and consequently, the formation of pan-crust or scratch-salt is completely prevented for as no evaporation takes place in the boiler no salt can be deposited there. There are a set of covers for diminishing at pleasure the evaporating surface, by which the fineness of the crystals of salt can be regulated with the greatest facility.

Excerpt from The Register of Arts, and Journal of Patent Inventions, 1828, Vol. 2 IN our address at the conclusion of the previous volume, we stated confidently, that our resources would enable us to continue progressively improving the work, ininterest, variety, and originality; a review of _our subsequent labours, will, we are assured, attest the honesty of our motives in making that statement; and establish the fact, of the improvement being considerable.

Excerpt from book: the other, so that each can be acted npon only by the pinion to which it belongs. The motion produced by this reciprocating machinery will be uniform throughout each stroke, which is not the case by a reciprocating motion produced through the medium of a crank, and this would be an advantage in many cases connected with the cotton and woollen manufactures; but the uniformity of motion throughout the stroke would decidedly be disadvantageous, when applied to pumps, the only instance of application mentioned by the patentees, for in them the gradual increase and decrease of motion produced by the crank at the beginning and end of each stroke becomes absolutely necessary, when the pistons, piston rods, and other reciprocating parts of the apparatus are heavy. Table-forks And Knife-suarpexers.?George Rogers, cutler, J. C. Hobson, merchant, and J. Brownill, cutler, all of Sheffield, Yorkshire, have patented an improvement in table-forks, by which they can be applied to sharpen table-knives. This improvement, though principally applicable to carving-forks, may be applied with advantage to other forks. It consists in attaching to the stem between the handle and the root of the prongs three or more projecting pieces of steel fixed to it by a screw pivot, passing through their centres. The edges of these steels, which are slightly fluted, to produce a filing action on the knives, are curved so as to form the same angle with each other, whether their roots or points are brought in contact to act on the knives. These projecting steels, when applied to carving-forks form a guard, and they are not much larger than the usual guard, and hence they become very convenient in use, as they are always at hand when required. This is certainly the best of the numerous knife-sharpeners on the same p...
