Title: Improvements in Apparatus for Searching for Submerged Objects.
Inventor: SCHOULTZ MAX VON
Filed: 1899-05-17
Granted: 1900-05-05
Abstract: 10,441. Schoultz, M. von. May 17. Submarine explorations, apparatus for making.- Relates to electromagnetic apparatus for searching for submerged objects, and consists of a finder A which is dragged through the water and is in electrical communication with a signalling-device C carried in one of the searching-vessels. The finder consists of a strong permanent magnet or electromagnet N', S', in the magnetic field of which lies a bobbin D of insulated wire connected to the signalling-device. Any change in the magnetic field of the magnet N<1>, S<1>, such as would be caused by the close presence of an anchor, ship, torpedo, or the like, would make a current in the bobbin D which would operate the signalling-device. The finders may be protected, and a number of them may be arranged on one cable B, or the finders may be carried by cables fastened to a transverse beam or to a transverse cable connected to two ships, and provided with floats. The signalling.device preferably consists of a telephone, in the circuit of which is a commutator or an interruptor of high frequency, as in the Hughes' induction balance, whereby a current in the bobbins D is indicated by a picking in the telephone. In a modification, the signalling- device may be placed in a secondary circuit which is operated by the current in the bobbin D. A switch of great sensitiveness, or a relay of two bobbins of insulated wire connected in series and placed at a slight inclination so as to have a common diameter, are then employed. Means for making a permanent record of the positions of the ship when the finder passes the object searched for may be provided. The telephone may be replaced by an electric bell, or an indicating-board giving the number of the finder operated, or an alarm gun or means for throwing a buoy.

Title: A New or Improved Process for Reproducing Designs,Drawings, or Pictures upon Metal or other Surfaces.
Inventor: HADDAN HERBERT JOHN
Filed: 1900-04-17
Granted: 1900-12-01
Abstract: 7123. Haddan, H. J., [Daniel Process Co.]. April 17. Copying documents, drawings, and the like; photomechanical printing; developing. -Relates to a process for reproducing a copy of a design, drawing, or picture, upon a metal or other plate intended to be engraved. A photographic negative, of the original design &c. is prepared upon a glass plate 5, Fig. 6, and the raised parts 1 are coated with wax, Burgundy pitch, tallow, or other similar substance, so as to obtain a layer 10, which is pressed by means of a celluloid or other flexible sheet 11. This sheet is next carefully stripped off, so as to leave one portion 12 of the wax &c. coating adhering to the negative, while the other part 13 is stripped off with the sheet 11. The wax-coated sheet 11 is laid upon the metal &c. plate 3, Fig. 8, which is to be engraved, and, after having been pressed, is stripped off so as to leave a portion 16 of the wax coating on the plate. The wax coating 16 may be dusted over with finely-powdered resin and dragon's blood, and the exposed parts 17 of the plate subjected to the action of a mordant, such as nitric or other acid. Finally, the plate is washed with alcohol, turpentine, coal oil, or the like, to remove the wax and leave upon the plate a copy of the original design, drawing, or picture, in discoloured or stained lines. The plate, thus prepared, is ready for engraving. The photographic negative used in the preparation of the plate may be obtained in a variety of ways. The following is the method preferably employed :-An albumenized glass plate has its surface treated with collodion, which may be prepared from alcohol, ether, gun-cotton, ammonium iodide, and cadmium bromide. The plate is next placed in a very acid silver nitrate bath, and afterwards exposed so as to obtain a negative of the design. After exposure, the plate is developed, preferably by means of a solution containing ferrous sulphate, acetic acid, and water. If desired, the elevated parts of the film 1 may be thickened, preferably by treating the film with a solution containing Nelson's gelatine, water, ferric sulphate, iron perchloride, and tartaric acid ; the negative is then dried, exposed to the action of sunlight, and finally developed by means of a solution containing gallic acid, alcohol, and water. The plate 5, Fig. 6, may be made of flexible material, if desired, and the wax-coated negative may, in this case, be applied directly to the plate 3, without the necessity of using the flexible sheet 11. According to another modification, the use of wax &c. is dispensed with, and a mordant, such as sulphur, is applied to the elevated parts of the negative, or the intaglio parts may be filled with the mordant ; in this case, the negative is directly applied to the plate 3.
