Claims.—(1.) Process for receiving and at intervals storing messages, signals, or the like, characterized by the fact that a magnetizable solid body is influenced permanently and magnetically from a suitable transmitter in accordance with the messages or signals issuing from said transmitter, said magnetic influence being of such nature that the said body is inversely able at the desired time to repeat the messages or signals substantially as described. (2.) For carrying out the process specified in claim 1, an apparatus characterized by the fact that a microphonic, telephonic, or electric signalling-line is connected electrically with an electro-magnet which magnetizes a magnetizable body situated in its immediate vicinity, during the relative movement between the said magnet and the said body, at different places corresponding to the messages or signals sent at the time, and which body can then, with the help of a telephone or the like, give forth again what it has received, and will also be ready, after having been demagnetized, to receive a fresh message, constructed and arranged substantially as described. (3.) For carrying out the process specified in claim 1, an apparatus characterized by a pulley or a cylinder with steel wire coiled spirally round it, which is placed in contact, during the reception of a message or signal, with an electro-magnet which is moved around the same, and whose magnetism is dependent on a microphonic or telephonic current circuit included in the same line, constructed and arranged substantially as described. (4.) A form of construction of the apparatus specified in claim 3 characterized by the fact that the electro-magnet core is lifted by a spring 1 off the wire spiral g until, in setting the apparatus into operation and rotating the electro-magnet around the cylinder d, the lever k is shifted by centrifugal force and by this means presses the electro-magnet core i against wire spiral g, constructed and arranged substantially as described. (5.) A further modification of the apparatus specified in claim 3, characterized by the fact that, instead of the wire spiral, there is employed a steel strip which is moved past the electro-magnet core, constructed and arranged substantially as described. (6.) A modification of the apparatus specified in claim 5, characterized by the fact that the line current causes a clockwork to be thrown out of operation, which has the function of closing a local-current circuit for a period corresponding to the duration of the conversation, for the purpose of moving the steel strip past the electro-magnet during the duration of the conversation, constructed and arranged substantially as described.

No. 12306.—13th January, 1900.—WILHELM SCHMIDT, of Wilhelmshohe, near Cassel, Germany, Engineer. Improvements in compound engines.

Claims.—In a compound engine with differential pistons, the combination with an intermediate chamber u' constantly being in connection with the upper side of the large piston F', the ring-surface of said piston alternatively being in communication with the intermediate chamber and the exhaustor—first, for attaining a double-acting machine, and, second, for attaining an effective initial heating of cylinder and piston, for the purpose as described.

No. 12328.—4th April, 1899.—ROBERT SKELTON, of 40 and 41, Aungier Street, Dublin, Ireland, Tailor and Outfitter. Improvements in or relating to ladies' cycling-skirts.
[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.) Providing a lady’s cycling- and promenade-skirt with double- and single-holed rings at the front and rear inner parts respectively, as specified, the rings having a runner-cord in such position that the rear lower part of the skirt can be drawn close towards the legs, and the upper front down for the lap portion to lie upon the knees and the lower front to fall freely, as described, and substantially as shown. (2.) A cycling- and walking-dress skirt having the cord guide ring D secured at the rear, directly below the bustle portion; the cord guide-ring A secured to the centre of the front; the cord-hole F at one side, near the waistband,
and the continuous single cord C secured at one end to the front ring, passing back loosely through the rear ring, thence passing forward through the front ring, and thence ascending to and through said cord-hole, all as shown, whereby the central rear part of the skirt is drawn forward, and a central front part below the abdomen is drawn rearward, by pulling said cord.

No. 12380.—15th February, 1900.—EDWIN TOMS, of Wellington, New Zealand, Inventor. An improved cowl for chimneys and ventilators.

Claims.—(1.) A cowl for the purposes set forth, comprising in combination a pipe, loops attached to the pipe, and crossed over one another so as to have openings for the emission of smoke or air, substantially as set forth. (2.) A cowl for the purposes set forth, comprising in combination a pipe, loops attached to the pipe and crossed over one another so as to leave openings for the emission of smoke or air, and wire netting across the said openings, substantially as set forth. (3.) The improved cowl for chimneys and ventilators consisting of parts constructed and arranged substantially as set forth.

No. 12381.—15th February, 1900.—HURRY AND SEAMAN’S PATENTS, LIMITED, of 2, Queen Anne’s Gate, Westminster, London, England (assignees of Edward Henry Hurry, of Bethlehem, Pennsylvania, United States of America, Engineer, and Harry John Seaman, of Catasauqua, Pennsylvania aforesaid, Chemist). New or improved process for the manufacture of Portland and other similar cement.

Claims.—(1.) The described process for cooling hot cement clinker which consists in reducing the hot clinker to a broken condition, wetting the hot clinker, and subjecting the wet and broken material to a cooling atmosphere. (2.) The described process for cooling hot cement clinker which consists in breaking and wetting the hot clinker, and then rapidly evaporating the moisture from the broken material. (3.) The described process for cooling hot cement clinker which consists in breaking and wetting the hot clinker, tossing the broken material, and rapidly evaporating the moisture therefrom. (4.)
