IT has long been the opinion of many Scientific Men, Inventors and Manufacturers, that it would be of the greatest utility to establish in some central part of Europe, a Consulting Agency Office, directed by an experienced Engineer, who might assist Inventors by his experience and advice, to procure Patents (Brevets) and prepare the requisite papers, and to promote generally the interests of his clients. Influenced by this prevailing feeling on the subject, M. JOB DIXON, consulting Engineer, Knight of the Netherlands Lion, &c., has, at the solicitation of numerous scientific friends in England and the Continent, opened a Patent Agency Office at Brussels. Rue d'Artifice, 84, bis, Boulevard de Waterloo, Where orders will be received for the Procuration of Patents of Invention for the various States of Europe, and the United States of America; and where Mr. DIXON may be personally advised with on all matters relating to the Securing of Patents for Inventions or to the working of the same. Persons favouring Mr. DIXON with their commands, may rely on the most judicious care, confidence, and dispatch. N.B. All letters or packages to be addressed post-paid. OMPANY. Wharf Road, City Road, London. IT cannot now be doubted even by the most sceptical, but that GUTTA PERCHA must henceforward be regarded as one of the blessings of a gracious Providence, inasmuch as it affords a sure and certain protection from cold and damp feet, and thus tends to protect the body from disease and premature death. Gutta Percha Soles keep the feet WARM IN COLD, AND DRY IN WET WEATHER. They are much more durable than leather and also cheaper. These soles may be steeped for MONTHS TOGETHER in cold water, and when taken out will be found as firm and dry as when first put in. Gutta Percha Tubing, Being so extraordinary a conductor of sound, is used as speaking tubes in mines, manufactories, hotels, warehouses, &c. This tubing may also be applied in Churches and Chapels, for the purpose of enabling deaf persons to listen to the sermon, &c. For conveying messages from one room to another, or from the mast-head to the deck of a vessel, it is invaluable. For greater distances the newly-invented ElectricTelegraph Wire covered with Gutta Percha is strongly recommended. Mill Bands. The increasing demand for the Gutta Percha strapping for driving bands, lathe-straps, &c., fully justifies the strong recommendations they have everywhere received. Gutta Percha Pump Buckets, Clacks, &c. Few applications of Gutta Percha appear likely to be of such extensive use to manufacturers, engineers, &c., as the substitution of it for leather in pump buckets, valves, &c. These buckets can be had of any size or thickness WITHOUT SEAM or JOINT, and as cold water will never soften them, they seldom need any repair. Gutta Percha Picture Frames. The Gutta Percha Company having supplied HER MAJESTY THE QUEEN with several elaborate Gutta Percha Picture Frames for Buckingham Palace, which have been highly approved by the Royal Family, fully anticipate a great demand for frames from the nobility throughout the country. In order that the picture-frame makers may not be injured, the Company will supply the trade with the mouldings, corner and centre pieces, &c., and allow them to MAKE UP the frames. Pattern books for the trade are now ready. Gutta Percha soles, solution, inkstands, card-trays, medallions, picture-frames, brackets, mouldings, window-blind cord, soap-dishes, tap-ferrules, cornices, vases, fire-buckets, bowls, pen-trays, stethoscopes, thin lining, thread, flower-pots, ear-trumpets, &c., &c., manufactured at the Company's Works, Wharfroad, City-road, London; and sold by their Wholesale dealers in town or country.

BESSEMER'S FURTHER IMPROVEMENTS IN THE MANUFACTURE OF GLASS. THE manufacture of glass makes slower progress in this country, than was anticipated from the repeal of the duties, by which it was so long fettered and obstructed. We ought to be able to make anything in glass which is made in metal; so strong, indeed, is this impression among the glass-makers themselves that they are in the habit of calling glass itself a metal; but we are still very far from having arrived at such a consummation. There are a great many articles still made in silver, brass, iron, &c., as well as other substances, for which glass would be much preferable. We might fill columns with instances of this, but we refrain from doing so, lest we should forestall the labours of any inventor whose ingenuity may be applying itself in this direction. Another circumstance worthy of note is, that such improvements as have been made since the repeal of the duties, have emanated chiefly from amateurs or persons not practically engaged in the manufacture of glass. The workers in glass themselves have done but little. Among these amateurs none has so distinguished himself as Mr. Bessemer, of whose previous successful labours in this department of art, the reader will find some account in our xxxvii. vol., p. 98. Mr. Bessemer's present patent has reference chiefly to plate glass, and is prefaced by an exposition of defects in the existing system of manufacture, which is quite startling for the amount of vulgar error and ignorant practice which it displays. Whereas the ordinary casting table consists generally of a large plate of cast iron, from 12 to 15 feet in length, 5 to 7 feet in width, and from 4 to 6 inches in thickness, more or less, which is placed either on a bed of masonry or on a frame with wheels, and is planed to a true level on the upper or casting surface; and whereas, in order to cast plates of glass perfectly flat and of one uniform thickness, it is necessary that the table should maintain throughout the operation of successive castings, the same true plane as at first; but this is prevented by the unequal expansion of the iron; for as soon as the liquid glass is poured upon it, the upper surface of the thick table absorbs heat therefrom, and becomes expanded more than the under surface, producing thereby a slight curvature of the table, which curvature becomes greater and greater with the addition of each successive potful of glass. Again; the ordinary casting table is placed in a horizontal position, and the plate of cast or rolled glass has to be removed from it while in a soft state, and the force required to slide it off the table renders it necessary, that the end of the plate should be folded up, and a sort of peel or pusher placed within the folded portion, by which means the soft plate is made to move in the required direction, the folded portion going foremost. Although this causes a waste of the folded part, it is rendered necessary, by reason of the weight of the plate being too great to be pushed from behind edgewise on a horizontal plane, without putting it out of shape. Moreover, in the ordinary mode of casting on a table, the large roller which is passed over the glass to form it into a plate, is either allowed to fall down on a trestle when it arrives at the end of the table, or is removed on a frame with wheels; in either of which cases an interval is left between the end of the casting table and the mouth of the annealing kiln, equal to the diameter of the roller, which interval has to be filled up by a boarded or other surface, over which the soft glass is pushed into the oven; or the plate of glass is put upon a wooden truck, and wheeled by the workmen to the mouth of the annealing kiln. And whereas also kilns have for a long time been in use for annealing plate or cast glass, having the bottom, or floor, formed with fire-tiles laid on sand, and it is frequently necessary to employ a workman to get into the kilns to re-adjust the tiles; nevertheless the general surface they present is neither flat nor uniform, and as the soft sheet of glass takes an impress of the irregular surface on which it is laid, it thereby requires much more grinding before it can be reduced to a true plane; besides which, it has to be made much thicker than is ultimately required, in order to compensate for the loss in grinding. Again; the arched roof or crown of such kilns is generally very thick, and covered over with sand or other bad conductor of heat: the consequence of which is that they cool very slowly, that several days are ordinarily occupied in the annealing process, and thus a great many more kilns are necessary than would be required if the kilns were cooled down more quickly. In the ordinary kilns, too, the heat is derived from one or more furnaces in immediate connection therewith, |
