No. 15689.—3rd May, 1902.—GUGLIELMO MARCONI and MARCONI’S WIRELESS TELEGRAPH COMPANY, LIMITED, both of 18, Finch Lane, in the City of London, England. Improvements in receivers suitable for wireless telegraphy.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claims.—(1.) In receivers for wireless telegraphy, the combination of a core or rod of magnetic material and a varying or moving magnetic field. (2.) In receivers suitable for wireless telegraphy, the combination of a core or rod of magnetic material in a varying or moving magnetic field, and a coil surrounding the rod or core through which the received oscillations are caused to pass. (3.) In receivers suitable for wireless telegraphy, the combination of a core or rod of magnetic material in a varying or moving magnetic field, a coil surrounding the rod or core through which the received oscillations are caused to pass, and a second coil likewise surrounding the rod or core, and having its ends connected to a telephone or other suitable receiving-instrument. (4.) In receivers suitable for wireless telegraphy, the combination of a stationary magnet, a travelling metallic band in the magnetic field, and a coil in proximity to the band, substantially as described. (5.) Receivers suitable for wireless telegraphy, substantially as described, and illustrated in the drawings.

No. 15690.—27th November, 1902.—HEINRICH SEVERIN, of Achern, Grand Duchy of Baden, Germany, Director of a Company. Improvements in the manufacture of hollow glass articles, and in the machines therefor.

Claims.—(1.) The process of mechanically producing glass articles (bottles) characterized by the fact that the receiving-mould is at once opened after the introduction of the molten glass and the forming of the mouth, to prevent the glass from cooling excessively, whereupon the mouth-die is withdrawn and the erect glass lump supported freely by the mouth-mould and, blown by the admission of air, is turned through an angle of 90°, then whirled and rounded on a marver, afterwards turned downward and extended to the required length by swinging and supporting, and finally, after closing the finishing-mould, is finished by the further admission of air, it being at the same time revolved if necessary, while the mould parts, having previously been in contact with the molten glass, are cooled by the expansion of compressed air or gas, substantially as set forth. (2.) A machine for carrying out the process referred to in claim 1, characterized by a mouth-mould 38 mounted to revolve around a horizontal axis and around an axis at right angles thereto, and so arranged between a receiving-mould 6 and a finishing-mould 8, both consisting of two opening and closing halves, as to form the bottom part of the receiving-mould when turned upward, and to form the upper closing part of the finishing-mould when turned downward, substantially as set forth. (3.) In a machine of the kind referred to in claim 2, the arrangement of the mouth-mould 38 in a frame 7 revolving on trunnions 39 and actuated by a hand-wheel 10 and provided with bevel wheels 20, 21, actuated by a hand-crank 22 for the purpose of revolving the mouth-mould around its horizontal axis, and around its other axis at right angles thereto, substantially as set forth. (4.) In a machine of the kind referred to in claims 2 and 3, the use and application of a marver 16 guided horizontally toward the mouth-mould 38 and backward on rods 18, substantially as set forth. (5.) In a machine of the kind referred to in claims 2-4, the arrangement of a bottom die 14 beneath the finishing-mould 8 for supporting the pendent and lengthening glass bulb, substantially as set forth. (6.) A modified form of the machine referred to in claim 2, characterized by the fact that the mould and other parts (i.e., receiving-mould 6 and mouth-die 12) coming into contact with the molten glass are provided with hollow spaces or chambers and connections (26-29) for the admission of compressed air or gas, and also with fine perforations for the latter, for the purpose of cooling these parts by the expansion of the air or gas, substantially as set forth.
