Inventor: NIELSEN RASMUS ANTON
Filed: 1900-05-28
Granted: 1901-05-04
Abstract: 9785. Nielsen, R. A. May 28. Incandescent gas and oil lamps.-Relates to improvements on the method of preparing mantles and incandescent media described in Specification No. 2672, A.D. 1900, in which the oxides used were drawn out by the electric arc into threads which were manufactured into mantles &c. In order to obviate the difficulties, such as the formation of carbides, which have arisen from the direct application of the electric arc, the substances under treatment are placed in crucibles before being introduced into the electric furnace. From the molten mass thus obtained, the threads for manufacturing the mantles &c. are produced by mechanical means. The invention is applicable to all the earths and substances employed in the manufacture of mantles. Mantles thus produced may be provided with a pulverulent coating of one or of a mixture of two or more incandescing substances by immersing the mantles in solutions of suitable salts, and incinerating.

Patent GB-190107064-A (GB)
Title: Improvements in Mechanism for Controlling and Regulating the Supply of Fuel and Water to Steam Generators
Inventor: HOLT HENRY PERCY
Filed: 1901-04-03
Granted: 1902-02-20
Abstract: 7064. Holt, H. P. April 3. Feedwater, controlling.-Relates to automatic appa- ratusforcontrolling the supplies of feedwater, liquid fuel, and air according to variations of pressure in the boiler, applicable more especially in connection with motor vehicles. Plungers of unequal area are arranged in opposition, the plunger of smaller area being constantly under boiler pressure, while the plunger of larger area is alternately under the pressure of the exhaust steam of the engine and that of the atmosphere or condenser. The result- ing motion is utilized to actuate the several feed- pumps. When the boiler pressure rises above a certain point in relation to the exhaust pressure, the plunder remains stationary at the end of its out-stroke, and the pumps are not actuated. In the arrangement shown in the Figure, the end of the plunger g is exposed to the boiler pressure, and the end of the plunger e alternately to the pressure of the exhaust steam and that of the atmosphere or condenser. These plungers carry, between them, the piston b of the blower cvlinder a, by which air is supplied to the furnace. The plunger g is hollow, and works over the fixed plunger i, thus serving as the feed-pump for supplying water to the boiler. The discharge branch for the feedwater communicates by the opening n with the space o at the end of the plunger g, which is thus constantly under boiler pressure. The liquid-fuel supply pumps v are actuated by means of the rocking levers s, u, and the tappet rod q from the blower piston b. The lever s also operates the slide valve z by which exhaust steam is distributed to actuate the plunger e. The pumps may, however, be actuated in any suitable manner. For instance, both the feed and liquid-fuel pumps may be operated directly from the piston b by rods attached thereto. In another arrangement, a differential trunk piston, exposed on opposite sides to the boiler and exhaust pres- sures, respectively, operates a rotary blower, and also the feed and liquid-fuel pumps. In the case of a compound engine, the intermediate exhaust is preferably employed to operate the plunger e or its equivalent. A pilot burner fed by an independent gravity or other supply, is preferably employed.

Title: Improvements in Semi-automatic Telephone Systems
Inventor: FALLER ERNEST AUGUST
Filed: 1903-08-31
Granted: 1904-03-17
Abstract: 18,754. Faller, E. A. Aug. 31. Telephone systems.-In the form of the apparatus described, each subscriber is designated by a number of four figures. The calling subscriber sets four rings on his sending-apparatus to show the number of the called subscriber. The sending - apparatus when wound up first sends a current to light the call lamp on the exchange section of the calling subscriber. The operator inserts the answering-plug in the jack indicated, and depresses a trunking- key so as to connect up the impulse receivers for the thousands and hundreds numbers. Electric impulses corresponding to these numbers are now transmitted, and the impulse receivers rotate two switches by corresponding amounts. These switches close a local circuit which indicates the trunk line of the called subscriber on the trunking-panel, which is now plugged by the operator, and thus connected to the jack of the calling subscriber. By pressing the ring back key, the operator starts the impulse transmitters and receivers for the tens and units of the number of the called subscriber. This lights a lamp on the exchange section of the called subscriber, and the jack indicated is now plugged by the operator. The impulse receivers are rewound by solenoids on pressing certain keys. Keys are depressed to ring up the calling and the called subscribers, and to notify them that the line is open. The arrangement of the system is shown diagrammatically in Fig. 21, which represents the circuits for transmitting the tens and units impulses. The wheels 13, 14 are first set to the required number of tens and units, and, when rotated by clockwork, they send electric impulses equal in number to these numbers along the two metallic lines. These impulses actuate two receivers 87, 88 which turn switches so as to close the circuit of an indicating-lamp on the exchange section of the called subscriber. The wheels 11, 12 transmit impulses for the numbers of thousands and hundreds to two receivers (not shown) on the trunk circuits between 99, 100. The various circuits are controlled by the operators by the trunking-key 102, the ringback key 103, and a battery key (not shown).
